Research & Development 'Natablishuft, VISIT TO T.T.Co.. ME0011 DZPARTM, TT. BMW. Xth -T-1v- 19,56 The primary object vas the collection of 0.5 g. Boretall and this vas accomplished. Advantage ins taken during the visit to deal vith several other matters. W Settim, uo of Ovtical System for Fl-remoonce - The procedure to be adopted for the success= aligutnut of the various components used was demonstrated to me by Mr. Norseman. During the demonstration, it became apparent that the Ions umber (n08.4) %biah we had been given arlier by I.T.Oo., was incorrect. They had confuoed their lenses and : upport stands. The lens employed by then is probably a Hilger Ions F1172 - or perhaps F957. It has a focal length of 8-9 em. and to made in glass. As at present ve have only ordered a quartz condenser Ions, this can be rectified without difficulty. The concave mirror (from the Bramber Handset) vbich they use is mounted in its original mount and this makes for easy adjustment. We have only obtained the unmounted mirror and thin will need modification. (ii) &H.T. Unit - I.T.Co. had supplied a opera Z.H,T# Unit for the Autormol-or to repInce the defective one orl.ginal2y received. When this arrived at Southampton it was damaged, due to poor packing. kt I!r. Bootitroyd's req-iests I d1scussel the i3atter with the Physics Department, and left a note of what was wrong (crackad anode meal of rectifier velvej fractured Litz wire from displaced Z.H.T. transformer). Mr. Iles was awayp but big deputy undertook to deal with the matter. He thought they could ripply a replacement at once, but later found this uas impossible. They will ensure it vill arrive safely next time. They also supplied a further 18 smoke collection tubes for the Autommoker. We now have 2* dozen tubes, which is domen more than the original ardor. (iii) Smoke Trans Dr* Bentley lent me am* of the traps 1which th~7 use for smoke collection for qualitative snalynio of smoke. This in the type which Dr. Hughes will require for hie work. It will enable us to copy the I.I.Co. Platinum wire cage fitted at the end of the tube. (iT) Tavour Phase Cb-amat-m-hv - I.T.Go. have temporarily discontinued work on their apparatus, pending the construction of a Martin Gas Density Balance. They have borrowed from British Fetrckm Ressarah Laboratories a model of this In Perspex, which they have copied for uss, am a jig for the coostruction of one in copper block. This will operate at temperatures up to 300-35000 and should prove extremely sonsitiTes When this is finished, us shall be able to borrov the Perspex model, should we vish to construct a Gas Density Balance. A commercial model, made by Camalla, will be on sale for EMO shortly. (y) Basic Yraction of Smoke - Mr. Burgan, who is %arking on this agpeab of smoke, is developing the use of paper chromatographl to the isolation of components from this fraction. He uses p-aminobonsoia said, b7 cyanogen bromide as d t ti followed e ec , ng agent and his paper strips show the presence of at least six componento. Identification of the compounds thus revealed requires the preparation of likely degradation products of nicotine and the comparison of their behavior an paper chromatograme. To this and, he has been preparing mgmemins by the pyrolysis at 5700 of C-1) nicotine. Myonains will be m. source of g2E-nicotins and nicotyrins, also.
