DGF/r4,VKJ1VEEC/68 15th July, 1966 QUARTULY ?DORT APRIL - JO.?, 1966 INTRODUCTION During the quarter, a three-day conference was held at R. & D.E., at which members of the staff discussed the directions in which future research and development work could proceed. This was attended throughout by Dr. S.J. Green and other visitors from Millbank participated in sessions relevant to their own interests. The six sessions covered the major fields in the programme, e.g., Smoke Studies and Bioassay, Aerosol Physics and Filtration, Smoking Evalua~ion, Primary and Secondary Processing and BATEX, Application of Computers etc. Me experiment was very successful in acquatnting research staff of the lines of work pursued by the development engineers and vice-versa. At the end of June,- Mr. A.H. Wright retired from the service of the Company. During his service in R. & D.E., Mr. Wright established himself as an expert on primary process research and his experience and sound advice will be greatly missed by his colleagues. Members of the Intermediate Management Course at Chelwood paid a visit to R. & D.E. on the completion of the course. Special demonstrations Illustra- ting the work of the Establishment, were provided and the course members seemed to have found the visit very worthwhile. It is, perhaps, a matter for future consideration whether the visit would be even more useful, if It could be arranged during the IN Course. Membe rs of R. & D.E. staff have also greatly enjoyed and benefitted from ON BATCo document for Province of BritiSh Columbia I I November 1999 -2- ViSitS this quarter from colleagues in Research and Development Departments from Tcuisville and Sydney and Mr. Yallup visited Montreal. C-D NJ BATCO document for Province of BritiSh Columbia 11 November 1999 -3- PROJECT 1000 GENERAL RESEARCH AND DEVELOPMENT 1100 Analytical (Miss C.W. Ayers) (21) Work has now started on the development of an automated method for the determination of hydrogen sulphide in smoke. Results so far obtained'agree reasonably well with those obtained using the'manual method. The automation of the manual method has not necessitated any changes in the experimental procedure. (24) A report has been issued describing the automated method for measuring the nicotine alkaloids content of smoke and tobacco. The distillation and spectrometer cell units appear to be novel developments and aticempts are being made to obtain patent protection. (26) Work on methods for the colorimetric determination of calcium and magnesium in tobacco is still delwfed. (27) A near-infra-red water analyser has been constructed by Servomex, Ltd., and is now being evaluated. (S.R. Evelyn) (28) Two colorimetric methods, one based on o-aminobenz- aldehyde and the other based on 3-methylbenzothiazol-2- one-hydrazone, are being compared as to their relative merits for the determination of aliphatic aldehydes in cigarette smoke. By and large, the latter reagent . gives a higher result when used with whole smoke and vapour phase. 1200 Tobacco (Miss C.W. Ayers) (4) 'Ihe analysis of the tobaccos from various cigars BATCo document for Province of BritlSh Columbia 11 November 1999 -4- continues. niis work is going slowly because of the requirements of other commitments. (J.W.H. Segar) (5) All of the information made available to R.' & D.E. (F. Haslam) on infestation control is now belng reviewed for-incor- poration into a report. 1300 Cigarettes (P.J. Nicholl) (1) &all batches of'Ariel cigarettes of various* designs (R.G. Hook) were prepared for consideration by the U.S. Patent (I.W. Hughes) Authority. Further batches are nearing completion and will be sent to Millbank for assessment. (R.G. Hook) (2) A preproject appraisal of human smoking behaviour (F.F. Cinkotai) has been made. During this appraisal, the B. & W. ~7eport on smoking behaviour was received. Because of the con- siderable amount of work already done in Louisville, the R. & D.E. proposals for work have been re-appraised P-nd will be restated In the near future. (Miss C.W. Ayers) (3) The analysis of the tobacco and smoke from samples (J.D. Backhurst) C, and C6 has been completed and the results communicated to T.R.C. 1400 Process Research & Development (N.E. Willis) (2) There Is nothing further to report on the studies of noise abatement in factories. PROJSCT 2000 TOBACCO: RELATION OF CONSTITUENTS AND PROPERTIES OF TOBACCO T TO THE QUALITIES OF LEAF AND SMOKE TO THE AGRICULTURAL AND CURING PROCESS 2000 General (A.R. Cousins) (4) Further materials have been tested for their suitability ON BATCO document for Province of BritiSh Columbia 11 November 1999 -5- in the column fractionation of nitrogenous constituents extracted from tobacco. It is hoped to develop a scheme of fractionation which will replace the one devised by Frankenburg; this method should field fractions repre4en- ting distinct chemical entities. (5) The characterisation of the supposed amino-acid-N- deoxyfructoses has continued. A number have been prepared and their behaviour compared with that of the substances naturally present in flue-cured tobacco. (6) A report has been Issued describing the technique for determInIng the separate amounts of glucose, fructose and sucrose in tobacco. (7) The technique (2006) Is being applied to a range of different tobaccos. First results suggest that the standard Somogyi method somewhat over-estimates the reducing sugar content of many tobaccos. 2010 Waterloo (D.G. Felton) (1), (2) and (_3) Nothing to report. 2070 Colour (D-T. Wood) (3) An appraisal has been made of the present knowledge concerning the effect of moisture and temperature on colour changes. in tobacco. PROJECT 3000 CIGARETIE DESIGN: FACTORS AFFECTING THE FORMATION OF &VOYM-2 3000 Smoke Research - General (Miss C.W. Ayers) 4) The evaluation has continued of samples submitted for (C.I. Ayres) Project CONqUEROR throughout the Quarter. BATCO document for Province of Brifth Columbia 11 November 1999 -6- (MISS C.W. Ayers) (5) As Indicated in the last Quarterly Report, two (J.D. Backhurst) lines of approach, aimed at improving the smoking quality (I.W. Hughes) of GOLDCHARK cigarettes, are under investigation.. So far, changes In tobacco blend have prdu.ed little improvement. The addition of a number of additives has, however, shown promise and is being pursued. 3110 Characterisation of Tobacco as a Smoke Producer (R.E. Thornton) (16) The smoke from cigarettes made from a number of tobaccos - flue, Birley and fermented tobaccos respectively have been examined for the presence of dime thy lni tros amine. If this compound Is present in the smoke it is there in amounts less than I microgram per cigarette. (Miss C.W. Ayers) (17) The development of a G.L.C. method for the deter- (S.R. Evelyn) mination of acrolein in smoke Is still delayed pending the completion of work under 3150/21 and 22. (Miss C.W. Ayers) (18) A report has been issued on the modification of the existing method for the determination of phenols In smoke. (C. Valentine) (19) Work has been commenced on the factors controlling the production of gas phase and, more specifically, carbon monoxide In cigarette smoke. 7he variation in the monoxide levels during a puff has been measured for puff durations of.'2, 4. 6 and 8 seconds. The results sug,kest that diffusion and temperature play the major role in the delivery of carbon monoxide. (R.E. 11hornton) (20) The possible presence of 3-methvlchol&nthrene in the polycyolic fraction of cigarette smoke is of BATCO document for Province of British Columbia I I November 1999 -7- considerable Interest because of its carcinogenicity and the fact that the sterol compounds in tobacco might be precursors. Experiments are being carried out-to deter- mine whether the compound Ils present in smoke, and to establish an upper level of concentration. 3120 Tobacco Composition and Smoke Chemistry (D.J. Wood) (2) The tobacco produced in the 1965 greenhouse experi- (Miss C.W. Ayers) menta has been manufactured into cigarettes. Chemical analysis of the tobacco and smoke Is now being undertaken. (H.F.D. Dymond) (6) 7he work has beeA completed on the capillax-i (poly- (Kiss C.W. Ayers) propylene glycol) column analysis of the smoke from flue-cured, air-cured, and fermented tobaccos. The smoke (from the fermented and flue-cured tobaccos), after passage through a Bondex filter, has also been examined. The analysis of results has been badly delayed because of poor service from r.B.M. on the computer processing of the chromatograms. (Miss C.W. Ayers) (8) The analyses of Project AF samples 07 -.11 has (A.R. Cousins) been completed and the results are being evaluated. (A.W. Cronshaw) (R. Comber) (J.D. Backhurst) (9) The initial results from the experiments with a chamber as an "artificial mouth* have indicated that the total amount of nicotine retained is not very sensitive to eitherthe pH of the buffer solution which -lines the chamber or to the pH of the smoke presented to It. TKis BATCO document for province of BritiSh Columbia 11 November 1999 .8- work is continuing. (Miss C.W. Ayers) (10) A report has been issued describing the results of (R.E. Thornton) the analyses on the Mexican tobacco samples. (Miss C.W. Ayers) (11) Cigarettes produced i~ Belgi,. by a simulated "French (D.J. Wood) Process" have been compared with those produd ed' in the (J. D. Backhurs t) normal course of manufacture. 7he main findings were that the "French Process", when applied to the tobacco of a dark air-cured blend, led to an increase in the smoke pH and an increase in the delivery of "extractable 3140 O.R. Evelyn) (J.D. Backhurst) nicotine" sufficient to be detected by a smoking panel. When applied to the tobacco of a U.S. type blended cigarette, the "French Process" had no such effect. The Effect of Additives (6) A report has been issued on the transfer to main- stream smoke of glycerol, propylene glycol and di-ethylene glycol. (7) The initial experimental survey of the effect on smoke chemistry of treating tobacco with a variety of gases and vapours has been completed. (P.J. Nicholl) (8) The preliminary examination has been completed of the effects on the smoke composition of adding chlorides of cobalt, nickel and chromium to cigarette tobacco. (9) The effects of a wide range of additives on cigarettes made from CH102 blend have been examined to compare with earlier work on a single grade of tobacco. The results are being evaluated in combination with those from 3148. BATCo document for Province of British Columbia 11 November 1999 -9- (S.R. Evelyn) (10) The measurement of the extent of degradation of the glycols (3146) to acrolein Is still delayed pending the development of a reliable method for the determination of acrolein (3110/17)- -3150 Transfer and Pyrolysis Processes (J.D. Backhurst) (17) The experimental results from the work on the transfer of hydrocarbons -and eaters to smoke have been evaluated, and as a result it appears that the experimental procedures used were not satisfactory. Consequently the work will have to be repeated and as a result of this the report will be delayed for some time. (S.R. ~Velyn) (18) A report has now been issued on the application of the furnace technique to the production of aliphatic aldehydes. Because of the discrepancies in the results of the colorimetric assay as applied to whole smoke, work has been started to compare alternative colorimetric methods (1100/28). (21) 7he transfer of 6-methyleoumaLrin during pipe smoking has been found to be similar to that for coumarin. The transfer of dihydrocoumarin could not be measured. How- ever, with neither is there any evidence of degradation to coumarin itself. A report on this work has been Issued. (22) Experiments are under way to determine the levels of ethylene glycol and diethylene glycol in PEG 200, 400 and 600. Attempts are also being made to study the transfer of PEG 200 to mainstream smoke during pipe smoking. BATCo document for Province of British Columbia I I November 1999 CD Q-n 4 ~- -10- ,316o Development of Smoking Machines (N.E. Willis) (2) The report on the 12-port smoking engine Is delayed (Miss C.W. Ayers) because of other work. PROJECT 32M CIGAR= DESIGN: MODIFICAION OF SMOKE A FOWATION 3200 General (R.G. Hook) (1) The first set of theoretical experiments on the coagulation of cigarette smoke has been completed. 3200 Classification of Smoke Particles (R.B. Richardson) (6) The installation of the Conifuge has now been (F. Russell) completed. (R.B. Richardson) (7) The calibration of the Conifuge has been started. 3 i% Structure of Particles (R.B. Richardson) (3) She first series of results of the experiments investigating the deposition of smoke on standard surfaces are being assessed. (F.F. Cinkotai) (5) Although it has been possible to producir changes in the contact angle and woric of adhesion of smoke on glass surfaces, the expected correlation with the filtration efficiencies of beds of glass beads has not been observed. (R.B. Richardson) (6)' A report has been Issued on the effects of conc en- tration on.the physical properties of solutions of smoke condensate in aqueous acetone. Although concentration has little effect on the surface tension, the viscosity Increases quite rapidly at high concentrations. (7) As the result of a suggestion by Dr. Scurlock, the feasibility of detecting structures in smoke pairtIcles by C:> C::) N) 7 = BATCO document for Province of British Columbia 11 November 1999 X-ray diffraction is being investigated. 3250 Capture Probability (R.B. Richardson) (1) Since it has been established that the capture probability of smoke particles orr very fine platinum wires can, in some circumstances, be less than unity, an inves- tigation of the effects of wire diameter and flow velocity is being undertaken. PROJECT 3300 ME MAIN FACTORS =r UENCING TASTE AND FLAVOUR 3310 Analysis of Smoke with Respect to Flavour Compounds (K.D. Kilburn) (6) The data logger has been successfully installed and (A.E. Yallup) is operational. The G.L.C. programme was completed and tested using the data' logger; after some modifications it is now working satisfactorily. The programme In its present form is expensive and ways of reducing the cost are being studied. (C. Valentine) (9) The panel testing of some compounds isolated from smoke condensate is nearing completion. In the last Quarterly Report, doubts were expressed on the validity o~ testing compounds using good quality tobacco as a vehicle for those compounds. In this context, both good arA poor quality tobaccos were tested; the results were Inconclusive. (K.D. Kilburn) (10) Work has started on the development of a computer programme which will enable comparisons of smoke chroma- tograms to be made automatically. 3330 To Establish a Chemical Basis for Sensory Testing (K.D. Kilburn) (1) 1he testing of individual members of the panel and C__ BATCo document for Province of British Columbia I I November 1999 -12- (K.D. Kilburn) (H.F.D.

The results are now being analysea. (2) No work has been started on the applicazion of a digital computer to panel test results. (3) Two nitriles, found in cigarette smoke; 1dave been shown to give acceptable panel response in R. & D.E. Larger quantities are being prepared and puriffed for further testing by panels external to R. & D_7 In order -to obtain suitable patent protection (filed jure,, 1966),, a number of homologues are also being prepared for panel test. To Establish a Technioue for Assessing the Taste and Flavour of Whole Smoke (12) When testing cigarettes made by the "French Process" 0120/11) the performance of the duplicate Wor~=4ng Party compared favourably with that of the original i;orking Party. Further comparisons between the two a-re planned. (13) Because of discrepancies between some of -.:-.e analytical figures for nicotine delivery, the report on the relation between "extractable" nicotine and panel response will be delayed.

Thornton) (27) The filtration of benzpyrene by paper and ace--ate filter plugs was found, as expected, to be very si-flar to that of tar. She examination of the effects of a charcoal filter is in hand. (Miss- C.W. Ayers) (28) It has been suggested that acetate filters gf-,re rise (S.R. Evelyn) to formaldehyde when pyrolysed. Samples of Filtroza filters from Finland were received in R. & D.E. for exami- nation. At present, the determination of formaldehyde cannot be carried out in the presence of other materials arising from the pyrolysis of the acetate. However, attempts were made to determine whether formaldehyde was present when the filters were heated below decomposition, and none was found. (Miss C.W. Ayers) (29) A report has been issued on a Meerschaum caz-.ridge filter. (H.G. Horsewell) (30) Filters designed to provide "restricted" smok~_-g (F. Haslam) have been made. The pressure drops of the units axe still too high and the designs are being modified in an azz~empt to overcome this. No laboratory measurements have 7et been made. (H.G. Horsewell) (31) Filters made from polythene net supplied.by Saith (F. Haslam) and Nephew were originally found to be of little use as selective filters. 7his material, however, is now-being re-examined with a view to producing nelectrostatiem filters along the lines of the PLIOTRON filter which has CZ) 00 BATCO document for Province of BritiSh Columbia I I NOVGrnber 1999 -14- been designed to remove tobacco smoke from the atmosphe:,e in aircraft. The PLIOTRON filter material and information was made available to R. & D.E. by the Research Departmenz (I.T. Co. Bristol). .3410 Filter Additives (T.W. Tolman) (9) and (10) The synthesis of poly(vinylamine) has been comoleted and tested as a possible filter additive. 11he material appears to have no useful advantages over P.E.I. These results are now available to allow completion for patent application. (H.G. Horsewell) (11) and (12) A report has been issued detailing the (Miss A.G. Ivinson) effectiveness of zinc, bismuth, iron and titanium compourds as additives to filters for the removal of hydrogen sulp'nide from cigarette smoke. The data are being' used to complete the patent specification. (H.G. Horsewell) (13) The study of the factors affecting the performance of filters impregnated with F.E.I. has been completed. The results are being assessed. (14) A report has been issued on the Inorganic s< BONDEX filters. (H.G. Horsewell) (15) A sample of C14 labelled P.E.I. was received from (R.E. Thornton) B.A.S.F. Filters are being impregnated with this material, and the extent of transfer to mainstream smoke being measured. This work is being carried out to determine whether F.E.I. added to filters will transfer*to the mainstream smoke under normal smoking conditions. 0" cc BATCo document for Province of British Columbia I I November 1999 -15- (H.G. Horsewell) (16) As the second part of-the work being done for (R.E. Thornton 3410/15, attempts are also being made to determine how much radioactivity is carried over to the mainstream smoke when the burning coal of the tobaeco actually smoulders the filter. 3420 (H.G. Horsewell) (Mrs. S.L. Vekris) (H.G. Horsewell) 34,30 (R.G. Hook) Filter Materials (4) Samples of carbonised viscose fibres have been prepared at Salford C.A.T. which are similar in appearance to those made by Le Carbone, but which are less active and somewhat inhomogeneous. The work Is continuing in order to produce a material which corresponds more closely to that from Le Carbone. (5) 7he batch of viscose sent to Le Carbone for carboni- sation has not yet been returned. (6) Samples of the carbons, before and after purification, have now been received from Louisville. These will be compared with the carbon samples in R. & D.E. Mechanism of Selective Filtration (11) Differential equations for the simultaneous sorption or desorption of two components on a fixed bed of sorbent have been developed and solved analytically in a favourable case. A computer programme is being written to solve the equations in the more general case. (H.G. Horsewell) (12) The study of displacement of smoke constituents from carbon has continued. It has been shown that it is only possible to displace significant quantities of phenols QD G BATCO document for Province of British Columbia I I November 1999 -16- when the loading on the filter is very high. Initial results with hydrogen sulphide suggest that when this compound is adsorbed onto a carbon filter it is converted to other compounds, possibly sufphur dioxide.. (Mrs. S.L. Vekris) (13) Experiments on the effects of tobacco .type on-the distribution of aldehydes and pyridine between the two phases of smoke as separated by a Cambridge filter has been completed and the results are being evaluated. (14) Although attemptz to measure the vapour-particulate distribution in fresh smoke have been rather inconclusive, there are indications that the measured ratio of the con- centrations; in the two phases may change by as much as a factor of two according to the method of separation of the phases. PROJECT 3500 BIO-ASSAY STUDIES 3510 Project CONQUEROR (C.I. Ayres) (,3) A report has been issued on the initial results from the Goblet Cell Test. The results were encouraging and further work has been planned. 3520 Project JANUS (C.I. Ayres) (1) The results from the short-term hyperplasia, test indicate that a dose-response relationship exists. (2) The preparation of the cigarettes (BO) for the first long-term skin-painting experiment is in hand. 3530 R. & D.E. Studies (R. Comber) (3) Further pieces of 11-day embr7onic lung tissue from CX_1 ~Lpl BATCo document for Province of BrltlSh Columbia 11 November 1999 -17. hen's eggs have been treated with smoke condensate and with benzpyrene, in tissue culture. Neither of these agents induced hyperplasia. Both had clear, but. different, deleterious effects on str,:.ture, when the levels were high enough. An attempt is being made to deVe lop a quantitative method for measuring this deletelrious effect of smoke. (4) A report has been issued on the second method of measuring the toxicity of smoke to Paramecium. This method is being used in an attempt to discover the nature of the toxicity. (5) Some exploratory work has been carried out with the object of investigating the effect of smoke and smoke constituents on cells. Mie cells used have included isolated chick embryo cells, a large species of Paramecium and root-tip cells.

(28) Initial tests with simple rails appeared very promising. Further tests have been delayed by 3522. (29) Because of the poor performance of the 1964 A. 8 at 2,500 c.p.m.., a considerable amount of effort has been applied to finding the cause, and some improvement has been achieved. However, a further comparison with other type Mk. 8 machines indicates that the 1964 series is inferior.

Profile, ends penetration and interiorscope tests show no variation btweeh this garniture and a standard garniture, or between the calibrated garniture on machine OM.18258 and other machines. A few modifica- tions have been introduced to give better operating con- ditions and a more consistent initial setting-up procedure. It is intended to manufacture four more garnitures for appraisal on production machines in Southampton Branch. (A.W.

It has been established that a hIgh speed rotary, atomIser Can b.e used for the spraying of undiluted Folymin P. 4250 Packaging (D.E. Conway) (2) and (12) A report has been Issued detailing the further work on the transmission of water vapour through thin films. The results are used to calculate the rate of change of tobacco moisture content within a pack of cigarettes. Comparison of these figures with experimental results gives an estimate of the overwrap efficiency. Results are also quoted for measurements of film dimen- sional Instability and the effect on water vapour transmission. (N. Foster) (6) An Initial evaluation of the Molina-Stabilag hot melt unit has been made. The effect of thermostat setting variations has been examined and a recommended running procedure suggested. Three adhesives were examined in the unit and one of these, Swifts B.9918, has been recommended for further trials under production conditions. The unit has now been passed on to production for a further assessment. (D. E. Conway) M Two methods of studying the rate of flavour transmission have been developed and applied to a. system CD 0" 77 :77: BATCO document for Province of British Col Urnbia I I November 1999 -22- involving simple esters and- polypropylene film. (N. ?oster) (13) A performance study of the Molina WMH.2 overwrapper (D.-T Conway) has been carried out. The study included a comparison of the running properties of viscofe and polypropylene over- wrapping films; the running efficiency of the heaters was al so examined. As a result of this work, the WMH.2 machine has been modified in an attempt to overwrap and to heat tighten a polypropylene overwrap in one operation. (N. ?oster) (14) 7he general study of carton board creasing properties is continuing. An experimental creasing plan has been submitted to Chambon for costing purposes. Chambon have also agreed to provide a variety of production samples to enable a study of their standard production to be carried out. (D.E. Conway) (15) 7he selection and testing of materials for unit (N. Foster) cigarette packing is continuing. (N. Fcster) (16) Coatings have been assessed and approved, and (D.E. Conway) arrangements are in hand to produce cut and creased X.S. hinge lid blanks in a variety of slightly differing sizes. (N. Fbater) (17) 7he problem of removing the tightened overwrap from the 200's box is being investigated. It has been shown that the problem can be overcome by rendering the real along the back of the box strippable either by the application of a seal modifier, or by using a specially prepared overwrap film. The possibilities of patent protection for this idea are being Investigated. CD CZ) r\.) BATCO document for Province of BritiSh Columbia I I NOVOrnber 1999 -23- UNPROGRAY-,=- (D.E. Corway) In response to a request from Millbank a number of samples of soft cup packings were made up to represent.the possibilities available fo; increasing the rigidity of a 100 mm long soft cup pack. 7his work will be followed up at a later stage. 426c Filters (N.E. wi--is) (9) and (11) Following a visit to R. & D.E. of a (F. Russell) representative from Jensen & Son to see the Rultipass (Miss M.;. Ivinson) Filter Machine, it wasagreed that two patent applications should be made, one covering the manufacture of the continuous shaped rod required for insertion into the filter and the other covering the assembly of the final filter. The former application has been filed and the latter Is being processed. (F. Has!=) (10) and (12) Further samples of the prototype filters (Miss M.5. Ivinson) for restricted smoking have been prepared. A provisional patent application has been filed, and further experimental data Is being obtained for patent completion. 42 BO Cigars (J.K. MI:ner) (1) Two filter inserters have been constructed in R. & D.E. and one has been attached to a plug cutting unit from a Molins P.T.C. machine. An automatic mouthpiece feeder has been devised and fitted. The assembly showed a promising performance with the mouthpieces obtainable at present but final testing awaits the supply of mouthpieces with a 0- BATCo document for Province of British Columbia I I November 1999 -24- slightly different shape. BettiX Limited are having a new tool made that will produce mouthpieces which should be more comfortable for the smoker and which bill have an Internal chamfer to help the :ftisertion of the filter plug. The operating efficiency of the cigarlet assembler has been improved to a reasonable level by the fitting of a third roller. One thousand samples were produced for transmission to interested territories. A report has been issued in order to explain the cigarlet production method to interested territories. An automatic mouthpiece feeder Is being devised for the assembler. M-,ree assemblers, one each for Switzerland, Honduras and R. & D.E. 'are being made by Cannings, Ltd. Delivery is expected at intervals during June and July. Motors, guards, suction pumps and Automatic mouthpiece equipment will be fitted by R. & D.E. The prototype equipment has been demonstrated to represen- tatives of Vautier, Switzerland, who are to receive the first production set. (N.E. Willis) (2) In order to obtain further information on the use of (D.B. Naylor) the electrically heated die, a further series of tests (Miss M.G. Ivinson) were performed using 70 = lengths of both Perspex and Nylon tubes. 7he results showed that a satisfactory moulding could only be obtained If a slow and even pressure was applied to the die at an optimum temperature for each material. Any attempt to speed up the "pressing" phase when the material was softened resulted in buckling of the BATCO document for Province of British Columbia 11 November 1999 -25- tube wall. It is unlikely that this process is suitable for high speed manufacture due to the long moulding time required. In view of these difficulties, the patent application has been abandoed.

AND WASTE TOBACCO UTILISATION 5100 Waste Utilisation - General (F.j. Nicholl) (2) As a result of Mr, Gupta's visit to R. & D.E., further calculations on the economic feasibility of BATEX in India have been carried out. These allowed for devaluation of the Rupee and changes in the blend costs due to increased Tobacco Excise Duty and increased leaf costs. (5) The completion of the general survey of waste utilisation economics has been delayed awaiting information from Germany and East Africa. (8) The analysis of waste tobacco samples from East Africa has been completed, but further information is required before the economic appraisal of the BATEX process can be completed. (10) 1000.Kg of Izmir Scrap Tobacco has been received and arrangements are being made to evaluate the BAM product incorporated in the Virginia and Birley portiQn of RALEIGH cigarette blend.

Molyneux) (24) With the exception of the Allis-Chalmers Mill, for which a sound-proof box is being made, the design of a package plant for the production of BATEX has been com- pleted. A report on its design and operation is being prepared. (R.W. Hedge) (26) The feeder for metering cigarette rippings was not entirely suitable for BATEX. A simplified version of a Mk- 5 feed hopper has been built and will be tested shortly. (D.J. Molyneux) (27) 7he manufacture of BATEX from Singapore waste materia.1s, haz been completed and will be reported in conjunction with 5400/24. ?IzDJECT 6ooo 6 ooo General (A.H. Wright) (1) Comparisons between gas roasting and air dr7'ing of C.R.S. under normal factory conditions have confirmed the results of smaller scale experiments already reported. The trials have shown that the air drier designed for cut tobacco requires only minor modification for regular use with C.R.S. Uniformity of C.R.S. moisture content is comparable to that obtained with cut tobacco. Experiments BATCo document for Province of BritiSh Columbia I I November 1999 6500 (N-7. Willis) 66 co (J.K. Milner) (R. Smurthwalte) (Miss M.G.
