QUARTERLY REPORT January March 1962 PROJECT 1000 GENERAL RESEARCH DEVELOPMENT 1100 Analytical (Miss C.W. Ayers) (1) The method for the estimation of glycerol is being (6) extended to cover total polyols (I.e. ethylene and propylene glycols) in collaboration with S.C.L. (Liverpool). When the draft of the modified method is satisfactory to both Southampton and Liverpoolv the check test on tobacco samples prepared at Liverpool will commence. (4) A method has been developed for the quantitative estimation of the Individual sugars In Tobacco. Basically It depends on a paper chromatographic separation (developer butanols pyridinet water - 100:3) of an aqueous extract of tobacco which has been clarified with carbon. The eluted sugar concentration is determined by the Somogyi titrimetric method. The method is now being used to determine sugars in various tobaccos and in smoke. (5) The method of estimating chlorogenic acid and rutin has been used to analyse (a) various commercial tobaccos (b) experimental samples from Rajamundry (c) smoke samples (d) lamina, GRS and PCL samples A report is in preparation. (7) A reference catalogue of Infra-red and ultra-violet spectra Is being prepared. To date, spectra of fifty C six compounds have been determined and classified. Cr BATCO document for Province of British ColUrnbia I i Novernber 1999 (8) Preliminary experiments using a modified steam distillation procedure, developed by I.T. Co. (Canada), for separating other bases from nicotinet have shown considerable promise. Work is continuing and various 1200 (Miss M.G. Ivinson) tobacco and smoke samples are being examined. (9) Preliminary experiments have been started In an effort to develop a method for the qualitative and quantitative estimation of organic acids in tobacco and smoke. (10) As a result of a query regarding a corrosion problem in Kuala Lumpur, a sample of condensate has recently arrived at R. & D.E. Analysis of the condensate has been undertaken. ROUTINE ANALYTICAL SERVICE This involves a full time service for Karl Fischer estimations, metals, ash, silica, nicotine, sugars, uronic acids, tar, etc., and is reported under the individual projects concerned. Samples supplied for the collaborative test for potassium and chloride estimations organised by the Analytical Methods Committee of the Tobacco Chemists' Conference have been analysed. The results have been sent to Dr.C.L. Ogg (Chairman of the Committee). Tobacco (1) Blend Analvsis - The necessary apparatus has been purchased and trial Identification experiments startedg mainly along the lines of separating various lamina types. C:) BATCo document for Province of BritiSh Columbia 11 November 1999 (Miss C.W. Ayers) (2) Boxer tobacco - Samples of this tobacco plus a suitable control have been received from South Africa. Work has commenced attempting to find the casing/flavouring materials which may have been added to the Boxer tobacco. 1300 Ciqarettes (Miss M.G. Ivinson) (1) No work has been done, as a supply of E60 and Celanese process filter rods are not available. (2) Two further samples of filter rods for Australia were evaluated and the results reported to Purchasing Department. No further work is planned. (C.I. Ayres) (3) The effects of changes In atmospheric pressure on smoke yield have been examined and reported (L.47-F). No further work is planned along these lines. 1400 Process Research & Development (A.W. Cronshaw) The work for L.W.J. Milton on the B-A.T. Interpretation of the Factories (Ionising Radiations) Regulations was completed. As part of an examination of experimental procedure for measuring pressure drop the pressure drop of 200 filter rods was measured and the results reported internally. Laboratory Report No. L.42-F "Examination of Low Density Australian Cigarettes" was issued. PROJECT 2000 TOBACCO: RELATION OF CONSTITUENTS AND PROPERTIES OF TOBACCO TO THE QUALITIES OF LEAF AND SMOKE AND TO AGRICULTURAL AND AIRING PROCESSES 2010 Waterloo - Part IV. (D.G. Felton) The analytical investigations of the samples continues. (M.G. Ivinson) The programme was badly delayed owing to the late arrival of the representative samples of Rhodesian flue-cured leaf. L7 _9 t:1 U% BATCo document for Province of BritiSh Columbia 11 November 1999 - 4 - Samples of cigarettes for taste evaluation were distributed to Louisville, Montreal, Sydney and Johannesburg, as well as within R. & D.E. ' An attempt is to be made to correlate chemical analyses of tobaccos and their smokes with descriptions of physiological effect and taste of the smokes, and results from the different centres are now beginning to be received. 2020 Grev Tobacco (D.J. Wood) (1) A report on samples of leaf from field trials in India (R. Comber) Miss C.W. Ayers) has been drafted and will shortly be issued. Application of sodium chloride and potassium chloride to the soil increased the chlorine content of the leaf and induced a certain amount of greyness. (2) The report on the first greenhouse crop grown in 1961 has been issued. (3) Analysis of leaf samples from the second greenhouse crop, 1961, has continued. Storage at controlled humidity still awaits the arrival of equipment; as yet the leaf shows none of the characteristics associated with grey tobacco in spite of its very high chlorine content. (4) The work on pigment formation in tobacco is In abeyance. (5) Examination of grey tobacco samples from Pakistan has commenced. These differ in several important respects from any previous samples of grey tobacco examined at the R. and D.E. In particular they are comparatively low in chlorine but very high In aluminium and iron. Ur CYN 1 ~0 Ulj BATCo document for Province of BritiSh Columbia 11 November 1999 - 5 - (6) Seed for the first greenhouse crop, 1962, has germinated and the seedlings will be planted out shortly. The effect of a high iron level in the'nutrient solution combined with a high sodium chloride content will be Investigated. 2030 Preservatives for Raq Tobacco (I.W. Hughes) This project is now closed. In summary, the A246 was effective at 0.07%9 but the cost of the material has prohibited Its use. 2040 Nature of Water Bondinq (R.G. Hook) (1) Some progress has been made using the multiple re-drying technique, but the nature of the experiments tends to make the progress slow. (2) Differential Thermal Analysis apparatus Is being made. (3) Using the thermogravimetric balance, attempts are being made to obtain information concerning the activation energy required for release of water from tobacco. (4) Calorimetric measurements have been made on CNIOO lamina and CRS at different moisture levels. The results suggest that the method is not very promising for measuring the energies of binding of water in tobacco. It should, however, be possible to calculate these energies from observations of the vapour pressureAemperature relations of tobaccos at different moisture content. (5) Deuterium oxide exchange is being considered as another possible technique for answering the problem of water binding. It is intended to write a report recommending possible experimental approaches. C:> r-n -C~Ab CN BATCo document for Province of BritiSh Columbia 11 November 1999 - 6 2050 Gas Interchanae (I.W. Hughes) (1) An apparatus to enable tobaccos to be treated under pressure with gases and vapours has been constructed. Some trial runs with oxygen have not proved very successful as a means of changing the burn characteristics of the tobacco. Using various organic vapourst e.g. alcohols, the taste of the smoke from cigarettes containing the treated tobacco appeared to have altered somewhat. (R. Comber) (2) A report on oxygen absorption by, and carbon dioxide release from, tobacco is in course of preparation. Both absorption and release can be demonstrated at all stages of primary manufactureq the rates increasing with temperature, moisture content and air movement. More gas is exchanged when tobacco is cut than when whole. 2060 Fermentation of Tobacco (D.J. Wood) (1) The survey of published literature on tobacco fermentation (Miss A.M. Delamore) has been completed and a report issued. PROJECT 3100 CIGARETTE DESIGN: FACTORS AFFECTING THE FORMATION OF SMOKE 3100 Characterisation of Tobacco as a Smoke Producer %-.I. Ayres) (1/3) The study of the contribution of laminag stem and PCL, (H.G. Horsewell) and of repyrolysis has been divided into two parts: (i) tar and nicotine (11) 3.4 benzpyrene. ' Part 1 has been completed and reported (RD.lBg-R). The work for Part II is continuing. (M.G. Ivinson) (2) The report (RD.177-R) on the effects of strand width (A.W. Cronshaw) of lamina has been issued. c::> C71- BATCo document for Province of BritiSh Columbia 11 November 1999 (M.G. Ivinson) (4) The study of the influence of strand width of CRS on (A.W. Cronshaw) smoke production is progressing satisfactorily. Difficulties arose when attempts were madd to cut CRS at approximately 40 c.p.l., nevertheless sufficient samples were available. The firmness of these cigarettes was measured on the firmness profile integrating tester. (M.G. Ivinson) (5) The study of the effect of cigarette circumference on smoke production has been started; cigarettes have been made covering a circumference range of 23-27 mm. I.G. Ivinson) (6) The study of the effect of puff parameters has been started; the variables being employed are puff velocity from 8 to 20 ml./sec. and puff duration from one to three seconds. (C.I. Ayres) (7) "Operation Nightingale" - The experimental work is in the early stages and as yet no conclusions can be drawn. 3120 Studv of Pipes. Ciqars and Ciqarettes (C.I. Ayres) (1) The experimental work is virtually completed and a (H.S. Horsewell) report is in preparation. Briefly, It can be concluded that the benzpyreneAar ratios for cigar and pipe tobaccos In the cigarette form agree with the cigarette tobacco cigarettes. This supports the earlier conclusion that the mechanics of pipe smoking, rather than the tobacco itself, controls the higher benzpyrene production. (2) No work has been started on the effect of shapes and types of pipes on smoke yield. C) L71 -C:. 011 110 01-~ BATCo document for Province of BritiSh Columbia 11 November 1999 - 8 - (3) No further work has been done on the effect of non- porous combustible and non-combustible wrappers. Supplies of different porosity papers (from 0-350 B-A.T. units of porosity) have been requested. (4) Work has not yet started on the smoke production from tobacco treated by different leaf processes. 3130 The Characteristics of the Combustion Processes (R.G. Hook) (1) (5) A report has been drafted on the single thermocouple measurements of temperature profile. This has allowed the construction of a crude profile of the various heat zones which account for the composition of smoke. The purchase of the U.V. recorder (rapid response 0.01 secs.) has enabled a time-temperature graph at three points in a cigarette to be made simultaneously. This, It is believed, will give a more accurate distance - temperature profile within a cigarette. From the crude thermal profile the effects of heat on tobacco under inert and oxidising conditions are also being examined using the thermobalance, to aid the definition of the smoke producing zones. (Miss M.G. Ivinson) (2) The analysis of results obtained from carbon monoxide/ dioxide measurements is still incomplete. No further experimental work has yet been undertaken. (J.D. Backhurst) (3) Following the completion of the smoulder rate experiments (RD.172-F) the efforts were transferred to an assessment of 01% BATCo document for Province of BritiSh Columbia 11 November 1999 - 9 - side and mainstream smoke. The initial emphasis has been on obtaining a nicotine balance, and results so far obtained show that for total'smoulder, approximately 56% is recovered in the side stream smoke, whereas under a puffing regime (2 puffs per minute) the recovery (both main and side stream smoke) is increased to 75%. These results, together with some preliminary "tar" measurements, are indicating the respective efficiencies of the burning processes during puffing and smouldering. 'iss M.G. Ivinsony (4) No work has been done on the effects of puff profile, (K.D. Kilburn) mainly due to the demands on job 3314. 3140 The Effects of Additives (Miss M.G. Ivinson) The first report on the addition of such materials as chalk and charcoal is now completed. Of the materials examined, charcoal provides the most efficient quantitative reduction of tar (using the microtar technique). It Is now planned to study various particle sizes and degrees of activation. 3150 Transfer and Pvrolytic Processes .R. Evelyn) (1) A preliminary study of the release of nicotine from paper cigarettes is being carried out. It was first necessary to slow the combustibility of the paper cigarette and this was achieved by the addition of sugar and salt mixtures. By this means, the number of puffs required to burn a given length has been increa sed from 2-3 to 10-11. Various nicotine salts have been loaded on to the model cigarettes which c0 BATCo document for Province of British Columbia 11 November 1999 - 10 - were smoked. It would appear that the quantity of nicotine released is dependent upon the efficiency of loading the cigarettes evenly, and therefore makes interpretation of the results difficult. (2) The release of nicotine by dry distillation has been studied over an increased temperature range (to 3560c) using a furnace, which has been designed to eliminate tar formation for a variety of tobaccos and nicotine salts. While the release from nicotine chlorogenate is very similar to that from flue-cured tobacco, there is no apparent correlation between the dry distillation release and the chlorogenic acid content of the tobacco. (3) Work has been delayed on the rate studies of release and decomposition of nicotine until the construction of a vitreosil apparatus and modification of the gas chromatographic equipment has been completed. (H.G. Horsewell) (4) A method for the determination of scopoletin in tobacco and smoke has been developed. This method is now being applied to main and side stream smoke to determine whether or not the transfer efficiency differs from that of nicotine. 3160 Develooment of Smokinq Enq1ne (N.E. Willis) (1) and (2) No further development of the smoking engine has taken place other than the work on free and restricted smoking. (N.E. Willis) (3) The special solenoids and Cambridge Filter holders are now (C.I. Ayres) complete and special six channel face cam for timing their operation is being made. The apparatus when complete will permit a further study of the effects of "free" and restricted smoking. N-C BATCo document for Province of BritiSh Columbia 11 November 1999 - 11 - 3170 Weiqht of material burnt in a puff (A.W. Cronshaw) (1) The beta ray equipment was tested in its standard condition and was used for some studies of the performance of cigarette making machines. (I.W. Hughes) (2) The use of X-rays for measuring the weight of tobacco burnt in a puff is being investigated in Professor Mayneord's Laboratories in Surrey. PROJECT 3200 CIGARETTE DESIGN: MODIFICATION OF SMOKE AFTER FORMATION 3210 Goetz Investioation (J.D. Backhurst) (1/8) The investigation has been changed somewhat, in that the Goetz is at present being used to examine the smoke from pipes. Preliminary results show that the smoke particle size distribution is very similar to that from cigarettes. A study of the aging of smoke has also been commencect, and the experiments so far carried out suggest that the mean Stokes diameter of smoke increases from 0.44 to 0.6~L - 0.7~L after a standing period of 5 minutes. Other applications of the Goetz apparatus have been delayed somewhat due to structural alterations in the laboratory. 3220 Mechanical Filtration (Miss M.G.Ivinson) (1) The investigation of new surfaces has been temporarily suspended. (2) The calibration of various tobaccos as a filter media has been completed and reported (L.43-F) (3) No progress can be reported on the modification of filter surfaces mainly owing to non-availability of sufficiently interesting materials such as P.V.O.M. U_- 4!~. c0 BATCo document for Province of BritiSh Columbia 11 November 1999 - 12 - (4) The first part of the examination of the retention of water by filters has been completed. Briefly, the results show firstly that the coefficient of retention (CT) for water of both cellulose acetate and paper filters is higher than that for tar and nicotine and, secondly, that as would be expected paper is a more efficient remover of water than Is cellulose acetate. It is now planned to continue the study which is being broadened to include water release during the smoking of a cigarette. (5) There is nothing to report on the study of the re-evaporation of smoke condensate. 3230 Selective Removal of Vapours (1-:3) (Miss M.G.1vinson) The Initial troubles obtained with valves designed to sample smoke before and after the filter have been corrected. It is now planned to start work on the evaluation of various materials as vapour removers. 3240 Effects of Temperature on Smoke R.G. Hook) (1) All preliminary experiments on the effects of temperature on the particulate phase have been completed. The results are being combined with those from project 3131 in a report which is being drafted., (K.D. Kilburn) (2) Using capillary chromatography for compounds boiling up to 1180C, it has been shown that heating smoke up to 5700C does not alter qualitatively the vapour phase composition. 11 C LA~ cc BATCo document for Province of BritiSh Columbia 11 November 1999 - 13 - This may mean that the unpleasant smell and taste which occur when smoke is re-evaporated is due to changes in the higher boiling vapours or changes in the particulate phase producing unpleasant higher boiling vapours. (C.I. Ayres) (3) The Investigation of changes in filter efficiency with temperature is showing some interesting results, e.g. a 15 mm. Myria filter heated to 150 0C removes approximately 40% of tar, but only 6% of the nicotine from the smoke. This observation Is being pursued vigorously. 3250 Effects of Ions on Smoke (J.D. Backhurst) (1) This work has been completed, and has shown that smoking in an ionised atmosphere does not alter the tar and nicotine yield. This is understandable when it is realised that the cigarette produces its own Ionic field during burning. PROJECT 3300 THE MAIN FACTORS INFLUENCING TASTE & FLAVOUR A considerable portion of the work projected under 3300 has been delayed due to Compound A analyses. 3310 Analysis of Smoke with respect to Flavour Compounds (K.D. Kilburn) (1) Some preliminary separation of the carbonyl compounds (H. Dymond) in smoke was carried out and the infra-red spectra measured. It has been possible to identify 99% by weight of the C4, fraction. (2) Several chromatographic systems were tested for the separation of the base fraction of cigarette smoke. None was completely satisfactory. (3) There is nothing to report on the isolation of pure samples of tobacco aroma compounds. C: f,_T 41- 01 cc BATCo document for Province of British Columbia 11 November 1999 - 14 - (4) A series of analyses has been carried out on various samples of Compound A. In summary the work has shown that samples contained a number of impurities and that the main compound represents approximately 60 - 70% of the sample. Report L.44-R has been issued; and the final report on the stability of compound A is in preparation. 3320 Mechanism of the Release of Volatile Flavour Components (K.D. Kilburn) (1) The work on heating tobacco in gas streams has been (H. Dymond) delayed, because of projects 3314 and 3324. (2) The contribution of repyrolysis to flavour has been examined in two ways. (a) Using a cigarette as a filter, a number of cigarettes were smoked through it. The loaded cigarette thus obtained was then itself smoked and the vapour phase examined. Qualitatively there is little difference between the vapour phases from normal and smoke-loaded cigarettes. (b) Tar was collected on a n1chrome wire and then burnt. Analysis of the vapour phase composition showed that it changed depending upon the temperature used to burn the tar. (3) Studies on the correlation of yield of volatile materials to the burning of the tobacco in a cigarette are continuing. So far it has been shown that the vapour concentration increases with puff number and that contributions due to filtration and re-evaporation may be negligible factors. From a consideration of these factors, a rough product efficiency value has been calculated for the vapour generation by a lamina (MF2E) cigarette. 00 BATCo document for Province of BritiSh Columbia I I November 1999 11) ( j ~4 - I- k4 ,A - Z, Let - /~ " ~~~ ,.,F 'I *&--l -zr-xU VO C_- (_r -M ON %~c LN 00 4 t2l. BATCo document for Province of British Columbia 11 November 1999 - 15 - (4) Preliminary work has been started for the collaborative experiments with Louisville on the Reynolds additives. A column for the separation Of C3 - C8 aliphatic monocarboxylic acids has been prepared. 3330 To establish a Chemical basis for sensory tests (K.D. Kilburn) (1) The first series of smoking tests has been completed on the effects of additions of compounds present in smoke to cigarettes. A report is in preparation which indicates that some of the additives are detectable and that the threshhold level of detection varies with the type of additive. Generallys however, the threshhold level is more than ten times the ordinary concentration of the compound in smoke. (2) For the compounds tested, it has not been possible to develop a scale of acceptability, since in general they have not been considered pleasant. 3340 To establish a techniaue for assessina the taste and flavour of whole smoke. (D.E. Conway) (1) The strength tests on various commercial and single (A M. Delamore) et al grade cigarettes have been completed. The results were of sufficient interest to warrant a repeat series of tests. These have also been completed and are being analysed. The working party is now attempting a description of cigarette flavour, using American blended cigarettes. PROJECT 4100 PROCESS RESEARCH & DEVELOPMENT: PRIMARY 4100 Primary Process Research (S.J. dreen) (1) A collection of some Production Cost data has been made (A.J.0. Thomson) (F. Haslam) and this is awaiting more detailed study and classification. C=) fl-n -Ity. 0 N 110 LJ-j co L.rt BATCo document for Province of British Columbia 11 November 1999 16 (2),(3)& (4) (J.W.H. Segar) Further tests have been carried out in connection with (A.W. Cronshaw) (E.B. Wilkes) the Green Threshing experiments using Leaf and Lamina from Canadian and U.S.A. origin. * The Canadian series comprising a comparative test from each of the grades CE&CH available were processed with par dried C.R.S. added back to the cut rag prior to drying. These operations were followed with three comparative tests carried out on each of the U.S.A. (Western) Grades EB:X.2 and BF in which two tests from each grade had C.R.S. added back while in the third no C.R.S. was incorporated. Sample cigarettes have been made from each test for careful assessment and a composite report will be issued in due course covering the complete range of Rhodesiany Canadian and U.S.A. tobaccos used in the experiments. (Miss CA. Ayres) The nitrogen nicotine and sugar contents of all the green threshed tobacco (Rhodesian, Canadian and U.S.) and corresponding grades of tied leaf have also been analysed. Smoke analysis (tar and nicotine) has also been carried out. Sensory difference smoking tests are also being carried out. A considerable proportion of R. & D.E. effort has been taken up by this work in the past quarter and some projected work has been held up for several months. (P.J. Nicholl) (5) A study is being carried out of the various stages in (I.W. Hughes) primary Manufacture at which loss from tobacco may occur. It is planned to produce a programme of work for consideration. CO c7 N BATCo document for Province of BritiSh Columbia I I November 1999 - 17 - 4110 Tobacco Flow Problems (D.S. Goodfellow) (2) A preliminary report has been issued which describes and discusses a proposed modified form of making machine feed, the basic features of which are aimed to be simplicity and ability to handle a variety of blends. Experimental work has been carried out on two forms of conveyor. . (a) A fluldisation system. (b) A Fishlow-Hapman conveyor. The results of these tests are in course of analysis. (F. Haslam) (3) Experimental work on the Merchen Weighing Conveyor has been completed satisfactorily and a report is in course of preparation. (N.E. Willis) (4) The South African Load Cell Weighing Conveyor has been completed but testing will be delayed by the long delivery of the pneumatic control equipment. (A.H. Wright) 05) A Modified Pin Feeder is being designed and a series of (C.W. Ayers) experiments is being carried out to determine whether the C.R.S. distribution in cut tobacco can be assessed by means of nicotine analyses. 4120 Primary Process Devel6oment (ad hoc) (S.A. Grew) (2) Chromium (13%) stainless steel sprayed stem rolls are (A.J.0. Thomson) now being installed In the Southampton Branch Factory. This will facilitate a triple comparison test between these rolls and rolls with 18/8 stainless steel RTD cladding also in Southampton and rolls "Metallised" with 18/8 stainless steel in Liverpool. Weight loss measurements In connection with Beryllium-Copper scrapers are also in hand. 01 Oc BATCo document for Province of British Columbia 11 November 1999 - is - (D.S. Goodfellow) (3) It was decided at a meeting held in R. & D. with Southampton Branch representatives that the Microcell Limited proposals for the Southampton Branch Automatic Skip Filler were the most attractive. Final technical details of this unit have been ironed out and an amended quotation to accommodate a higher throughput and some further modific ations has been obtained. A final specification is awaited but this is not holding up the general progress. 4130 Basic Study of Tobacco Cuttinq 'N.E. Willis) (1) & (2) Following the completion of experimental work on (F. Haslam) the Molins Mark 1 and Mark 3 cutting machines it has been agreed to modify an existing Mark I machine to meet the demand of this work. Design work is now well In hand with the aim of providing the machine with independently variable cutting head r.p.m. and cheese velocity and hydraulically adjusted cheese pressure, and fabrication will follow. (F. Haslam) (3) Further investigations have been carried out into the differences between Molins Mark 1 and Mark 3 cutting machines in terms of the filling power of the cut tobacco. These have been reported in report No. RD.194 aind support the earlier findings. 4140 Stem Processino (J.V. O'Brien) (1) A report has been written covering the preliminary testing of the Eirich Mill for the shredding of stem. The main difficulties arising in this process are (a) the resinous deposit on the grinding plates and (b) rather high losses in the form of winnowings and dust. The filling power of the product appeared co c0 BATCo document for Province of British Columbia 11 November 1999 ~k t*p -C- cr- 1.0 LpJ cc 1 ~0 BATCo document for Province of British Columbia 11 November 1999 - 19 - to be considerably higher than conventional C.R.S. but this effect was not found when blended with rag. (A.H. Wright) (3) A single experiment has'so far been carried out in which undried C.R.S. ex cutters and lamina were Jointly fed to the air drying plant. Drying appeared to be quite satisfactory and there was no increase in spotting observed in cigarettes made from the tobacco. This work will be continued. (J.V. O'Brien) (4) The winnowings recovery planto the Eirich Mill (Model SF.9) and Its associated pipe feed and collection system, have been shipped to Geneva for factory trials on Geneva and Vautier winnowings. During these trials it was found that by removing rag from the winnowings in the air classifying section of a Formator, a considerably Improved performance was obtained from the Mill. The product was similar to C.R.S. but slightly shorter; it was considered suitable for blending with rag for cigarettes. One test was carried out on winnowings from Vautier Freres, Grandson. These were not cleared of rag and the result was poor. More tests should be done to determine whether this process can be applied to the Vautier winnowings. Report No. RD.195-R covers thE complete process. (A.J.0. Thomson) (5) Chilean stems can be darkened by passing them through a pipe feeder Into which steam is Injected. Possibly a water spray will be needed prior to the pipe. In the pipe the stems are raised to 200OF and on exit they are collected for four hours bulking. After this they are raised to rolling moisture and processed in the normal fashion. C71% BATCo document for Province of British Columbia I I November 1999 - 20 - (D.J. Wood) Optimum conditions for darkening stem are also being examined in the laboratoryp using the same technique as in the kinetic study of darkening In the manufacture of PCL. The work is nearing completion. PROJECT 4200 PROCESS RESEARCH & DEVELOPMENT - SECONDARY AND PACKING 4210 Ciaarette Makinq (A.W. Cronshaw) Report No. RD.173-F "Examination of the Cyclone Dust in the Mark 8 M.C.M." has been issued. (A.W. Cronshaw) (1) Diaries on the High Speed Mark 8 M.C.M. 0M.18258 are being .J.W.H. Segar) ~N.E. Willis) Issued at intervals. These diaries report the mechanical and operating performance of the machine. The testing (of the prototype High Speed Mark 8 M.C.M.) has continued. Some modifications have been fitted at Molins' request and their effect upon performance examined. To facilitate these modification trials a new system of proposal and reporting has been introduced. This should enable a more systematic assessment of the machine modifications to be made and facilitate the reporting on them to Molins Machine Co.Ltd. A report (RD. No. 199-R) on the comparative operating costs of the Mark 5 and Mark 8 Cigarette Machines has been written. (N.E. Willis) (3) The introduction of instrumentation of the cigarette making machine has been started. Apparatus for the first group of measurements is on order or under construction. (A.W. Cronshaw) (4) An examination was made of the firmness of cigarettes produced on the High Speed Mark 8 at 19000 c.p.m. and 2,000 c.p.m. No difference was found, so that the consistent improved firmne L71 -Ch. o,% %-0 L-*j BATCo document for Province of BritiSh Columbia 11 November 1999 - 21 - of the cigarettes produced by this.machine compared to the original Mark 8 is not simply due to the speed increase. Experimental work on Mark 8 degradation has been completed and a report issued. (N.E. Willis) (5) The Molins 585 Cigarette Making Machine has been delivered (J.W.H. Segar) (A.W. Cronshaw) to R. & D.E. and its installation Is complete. A programme of tests is being drawn up and a preliminary report should be available within 6-8 weeks. (A.W. Cronshaw) (6) An examination was made of the firmness of cigarettes made on the Mark 8s in Southampton Branch. An interim internal report was Issued and indicated possible large variations. This work is in abeyance because of pressure of other work. 4230 Modified Ciqarettes (D.S. Goodfellow) (2) In connection with the production of hollow mouthpiece cigarettes, trials have been conducted with a hot melt glue extruder on loan from National Adhesives, Slough. These were partially successful and the extruder nozzle is being redesigned. The main effortv however, Is being concentrated on the use of heat sealing papers by S. Jones and polythene coated papers by Telcon Plastics. These form the backing paper and outside cover. Greaseproof paper is used for the corrugated Insert for its stiffness and rapid heat transfer properties. Acceptable plugs have been made at a rate of 200 per minute - a target of 600 per minute is aimed at. Work Is at present restricted awaiting further supplies of coated paper. Deliveries of these are generally good. The first R. & D. progress report will be issued and it is expected that sample batches of cigarettes will be hand shortly.

Haslam) (1) A complete patent specification for the pneumatic conveying system for cigarettes has been prepared and submitted. 4250 Packaqinq (S.J. Green) (1) Since the measurement of water vapour permeabilities (S.A. Higgs) of packing materials will be important, a series of humidity vessels has been devised. The range of humidity Is provided by saturated salt solutions. An improved form of vapometer has also been designed which will facilitate permeability measurement. A survey of the literature on this subject is also in hand which will be of value in programming future research. PROJECT 4400 QUALITY CONTROL DEVELOPMENT 4410 Particle Size Analvs1s (A.W. Cronshaw) (1) The Assessment of the Canadian sieves was held up by shortage of staff but Is now in progress. (N.E. Willis) (2) The Wiggins Teape visual counter has been delayed owing to late delivery of components. It is now complete and testing can start Immediately. (J.D. Backhurst) (3) The usefulness of the Flying Spot Particle Resolvert made by Rank Cintel Ltd.r has been examined and one will be purchased by R. & D.E. (J.V. O'Brien) (4) An elutriator has been built to see if it is possible to obtain a separation of rag and winnowings. Some modifications In the design have held up the practical work. 4420 Ends Test Equipment (A.W. Cronshaw) (1) The I.T. Co.

Cronshaw) (1) The results obtained with the Molins Analyser on the Branch Cigarette Making Mac~ines were reported at intervals. As a result of the variations found between machines Molins arranged for their Engineers to improve the performance of the Branch machines. (A.W. Cronshaw) (2) The Solartron computor was returned to the suppliers and was completely rebuilt by them because of its unsatisfactory condition. The computor has been returned to us and we are awaiting the handing over after re-Installation. 4440 Development of Laboratory Tests (A.W. Cronshaw) (1) A report has yet to be written on the A.M. & F. Cigarette Comparator. (A.W. Cronshaw) (2) A.M. & F. supplied an electronic cigarette weigher for test and this was given a very thorough test during the sorting of cigarettes for another project. (A.W. Cronshaw) (3) Some work has been done on the building of suitable equipment to measure the pressure drop of a column of tobacco. (N.E. Willis) (4) Two standards for the F.P.I.T. have been produced and the initial checking carried out. The results to date are encouraging and at present they are being used for a daily calibration of the F.P.I.T. units used at R. & D.E. Six further standards are under construction. (N.E. Willis) (5) An experimental Hydrostatic Firmness Tester is almost completeg and it is expected that tests on the unit will be started within the next few weeks.

Yallup) (5) The development of the continuous pipe feeder/moisture meter Is continuing with the redesign of the electrode system. 4520 Samole Testinq Moisture Meters (A.E. Yallup) (1) A redesigned Kappa moisture meter has been demonstrated at R. & D.E. The manufacturers have promised a unit for test as soon as they are satisfied on a number of points. (A.E. Yallup) (2) Laboratory test to establish the tobacco temperature sensitivity of the Kappa 55 moisture meter is in progress and will be reported when complete. (A.E. Yallup) (3) The universal curves for the Kappa 55 have been rechecked and the extension of the curves for the Marconi Moisture Meter is almost complete. BATCo document for Province of BritiSh Columbia 11 November 1999 - 25 - (A.E. Yallup) (4) The design and construction of the Plessey Small Sample Moisture Meter is virtually complete and preliminary tests will commence when injection moulded sample cells are received. (A.E. Yallup) (5) The six Plessey Whole Leaf Moisture Meters are on order and delivery is due in 6-8 weeks. 4550 RaDid Filter Evaluation (N.E. Willis) (1) - (4) Two filter meters have been made In R. & D.E. and (A.E. Yallup) (A.R. Cousins) are now complete. One of these units will be sent to B. & W. Louisville for assessment. A Report and Operating Instructions Manual have been written. A further two units are to be constructed. PROJECT 5000 P.C.L. 5000 Basic Research (D.J. Wood) (1) Work has continued on the Identification of the chemical reactions which lead to darkening during the manufacture of PCL and a report will shortly be issued. (D.J. Wood) (2) Further kinetic studies of the darkening reaction are in progress. (R. Comber) (3) Microscopic examination of PCL bleached by sodium hypochlorite using transmitted polarlsed light reveals something of its structure, in particular the size and orientation of the anisotropic stem and vein particles. Thin transverse sections of PCL have also revealed something of the structure, but good sectioning has not proved possible. C71% BATCo document for Province of British Columbia 11 November 1999 - 216 - (W.B. Fordyce) (4) The identification of constituent sugars In tobacco polysaccharides has been completed, and report RD.187-R issued in respect of the work*done. Electrophoretic methods have since become available, and Indicate the presence of small quantities of mannan polysaccharides in the sample studied. (W.B. Fordyce) (5) The study of molecular weight methods for polysaccharides (A.R. Cousins) has continued. The application of the viscosity method to samples of tobacco celluloseq pectin and xylan, has shown promise. Tobacco cellulose has a molecular weight typical of plant celluloses (72000 x 162) and the pectin result is also in line with others published for similar plant material (125,000), Osmometry has been applied to a few polysaccharlde derivatives to give number-average degrees of polymerisation in line with the viscosity-averages obtained. Preliminary trial of an ebulliometer is in progresso (W.B. Fordyce) (6) Cellulose and pectin can be isolated with a high degree of purity. The resolution of mixtures of the less abundant polysaccharides is proving characteristically difficult, but progress has been made In the case of xylan and galactan. The structure of the various polysaccharides isolated is being studied by conventional carbohydrate techniques (end-group determination, periodate oxidation and methylation). (7) Physical testing of films, sheet, etc., was suspended from the programme to conform with changes In direction of the main PCL programme. C_r -tb. C71. BATCo document for Province of British Columbia 11 November 1999 - 27- (P.J. Nicholl) (9) Further work on Reynold's PCL has been completed and et al the results are being collated in a report to be issued. (W.B. Fordyce) (10) Analyses of the cell-wall carbohydrates of a number of different tobaccos and PCL continue. Five samples of American PCL and three samples of flue cured American tobacco have been analysed and the work is being extended to a number of different tobacco types. (D.E. Conway) (12) No more work has been carried out on the large scale application of ion exchange to the treatment of the liquors from the VS/PCL process. Initial laboratory experiments indic2ted that, by cation exchange, it was possible to improve the colour of VS/PCL for Australia. However preliminary large scale experiments were unsuccessful. (W.B. Fordyce) (13) Pectin appears to be the most abundant single polysaccharide in tobacco, in at least a few cases - greater (in quantity) than the cellulose "back-bone". This suggests that pectin fraction is the one most deserving of attention, since its many chemical features (ability to form gels, insoluble salts, esters, etc.) will have an important effect on the properties of tobacco and PCL. Consequently, an examination of pectins in tobacco has commenced. 5100 Castinq Processest Technical Development (P.J. Nicholl) (1) The proposed work with the Aylesford paper beater, in order to circumvent the Philip Morris patent (B.P.871,952) still awaits delivery of the new stainless steel rotor and stator. When these are received it is hoped to obtain information for a patent application. %10 CO BATCo document for Province of BritiSh Columbia 11 November 1999 CCL V 'Ili U- 4 ~A~ OIN 1-10 1110 %10 BATCo document for Province of British Columbia 11 November 1999 - 28 - (N.E.

(3) Work on the Plessey film moisture meter has been abandoned since the operating principle was found to be unsatisfactory. (P.J. Nicholl) (4) In the last quarterly Report It was stated that the work on the calendering of VS/PCL had been completed. Tests, carried out on cigarettes incorporating calendered and uncalendered PCL, were inconclusive. Further runs have been completed and the results are being examined. (8) No further patent applications have been filed during the last three months to consolidate the VS/PCL patent structure. An extensive patent survey was made to substantiate the inventiveness of the MK.II process and recommendations made that this process is both novel and patentable. D.E. Conway) (9, 10) The preliminary report on the elimination of P.J. Nicholl) ~ homogenization from the VS/PCL pro'cess, which was referred to in the last Quarterly Reportq was in fact, not issued. Plant trials followed quickly on the earlier results and all this work will be incorporated in a single report to be issued shortly. 5200 VS/PCL Introduction of process to other territories. (P.J. Nicholl) (3) The manufacturing guide for MK.II VS/PCL for South Africa (D.E. Conway) has been issued (RD.191-R). A batch of PCL made by the recommended method has been sent to U.T.Cos. (South), for evaluation in their own cigarette blends since it was not possible U-1 BATCo document for Province of British Columbia I I November 1999 - 29 - to simulate suitable blends in R. & D.E. (J.V. O'Brien) (5) A cost analysis, to establish the general conditions for the smallest economical Plant, has been completed (Report No. RD.182-R). This report has been considered with respect to particular territories but no new possibilities for the introductions of the MK.II VS/PCL process have been revealed. (P.J. Nicholl) (6) The experimental investigation into the utilization of Belgian shag waste, has been completed and reported (Report No. RD.197-R). (7) Work on the manufacture of a cigarette wrapper from VS/PCL and short length fibres has been started. (J.V. O'Brien) (8) A visit has been paid to the Simon-Carves Monsanto (P.J. Nicholl) Effluent Advisory Service to discuss the problem of the treatment of effluent from the VS/PCL process. This Is of particular interest in the case of South Africa. 5300 Paper processes (1) The plant at Vautier Freres~ Grandson, has been refurbished but the decision whether to carry out development work on this plant has still to be made. This depends not only on the outcome of the winnowings shredding work being carried out at Geneva but also on the wider issue of whether to develop any form of paper process for PCL manufacture. (P.J. Nicholl) (2) A report, on the economics of the paper process for PCL manufacture, has been written (Report No. RD.190-R). As a basis a Fourdrinier machine, such as used by I.T. Co. at Bristol, was considered. This would produce 70 lb./hr. of dry uncoat, base sheet from tobacco stems. This could be coated with st BATCo document for Province of British Columbia 11 November 1999 - 30 - extract and ground tobacco. (4) The formulation of a practical programme for the study of paper type processes requires the answers first put to a number of questions. (J.V. O'Brien) (5) Small scale experiments have been carried out on the (P.J. Nicholl) coating of paper with stem extract and tobacco flour. These indicate the possibility of loading with up to 5 parts of tobacco flour to each part of stem extract and base sheet. Development work will continue on the 90' band and the variation in filling power with loading studied along the lines indicated in Report No. RD.185-R. 5400 New processes. (1) Work on the extrusion of filaments of tobacco has continued. Indications are that a satisfactory product may by obtained using ground tobacco, water and glycerol only. (D.E. Conway) (2) The evaluation Is in hand of filters composed of filaments (Miss.M.G. Ivinson) of low molecular weight polythene, made by a novel spinning process. This work will become part of Process Research in the future. (3) No work has been done on the puff drying of PCL. 5500 T.S.U. process (P.J. Nicholl) (1, 2) No work has been carried out on the T.S.U. process for Belgium and South Africa awaiting information which will allow the profitability to be determined. (N.E.

(2)0 (3) A study of the effects of.an ethyl alcohol spray on small quantities of cured tobacco has shown that commercially attractive filling power improvements can be obtained. (A.W. Cronshaw) (4) The experiment on the effect of width of cut on the firmness of cigarettes made from lamina was repeated and reported internally. This showed that the cutting machine had a large effect on the firmness and density of the cigarettes. (F. Haslam) (5) A report has been prepared covering both the improvement of (See also filling power using dielectric heating and the rapid continuous, 4240) differential drying of cigarettes. On the basis of this report it is proposed to modify a making machine to incorporate rapid cigarette drying. (6) The study of the additivity of various filling power improvement techniques has continued as conditions have allowed. The results of these tests have, as yet, shown up no new information but have tended to substantiate earlier observation. 6100 Development of CONCYL and CONAIR (F. Haslam) (1) A short gravity pipe feeder for use with steam injection has been designed, developed and tested. It requires a headroom of just over 7-ft. and being an 8" round pipe can cope with a throughput of 2,000 lb./hour.

(3) A higher troughput short oval CONCYL/CONAIR gravity feed pipe has been designed, constructed and tested. To date a maximum throughput of about 4,500 lb./hour has been attained, but this is expected to be Improved upon. (A.H. Wright) (5) As an alternative to rotary locks as air seals In pneumatic equipment, a satisfactory method of using the gravity feed pipe has been devised with the tobacco bed providing a seal. (7) The build-up on the walls of an air dryer appears to be a very small proportion of the total quantity of material processed and analysis has shown high ash and silica contents for the material (40% ash in a residue from Amsterdam). (A.H. Wright) (8) The problem of steam distribution in the gravity pipe (A.J.0. Thomson) feeder is being analysed and practical tests are being planned. (9) A 4" bore gravity feed pipe with steam injection for the treatment of C.R.S. has been constructed and is now ready for testing. (F.
