Abstract: 399,786. Colour photography and kinematography. COOPER, E. D. and DAVIES, J., 468, Hawthorne Road, Bootle, Lancashire. Feb. 10, 1932, No. 3923. [Classes 97 (i) and 98 (ii).] In a process of projecting pictures in colour in a kinematograph or like apparatus, a group of component colour record images prepared from negatives taken through two or more complementary colour filters is projected in superimposition on to a screen, all the images or certain only of them being projected through a filter coloured by treatment in a solution of aesculine or of #-naphthol-disulphonic acid and certain through a different filter. In the case of a film, the component colour records are in recurring series each comprising all the records corresponding to one colour and all the series or certain only are projected through the aesculine filter. The filter may comprise rose bengal and patent blue in addition to the aesculine or #-naphtholdisulphonic acid. The whole film may be treated by bathing it in a solution of the filter dyes or in the case of a two-colour film, only the green component images may be so treated, the red component images being treated with a dye absorbing all the colours from 6250 mÁ to the violet end of the spectrum. Other pairs of complementary colours may be used similarly. In place of dyeing the film a separate filter may be used.

IPC: C07C69/24
Filed: 1960-02-06
Abstract: <PICT:0968083/C1/1> <PICT:0968083/C1/2> A continuous esterification process comprises reacting a carboxylic acid, a carboxylic acid anhydride or a partially esterified dicarboxylic acid which is less volatile than water with an excess of an alcohol which is more volatile than water and the ester produced and which does not form a water azeotrope, by heating in a reactor to which the reactants are fed separately in counter-current flow, removing from the reactor 2 (see Fig. 1) a vapour mixture of the alcohol and water, introducing this mixture to a distillation column 8, passing alcohol vapour from the head of the column to a heat exchanger 4 wherein heat from condensing alcohol vapour is transferred to dry alcohol passed through the heat exchanger to the reactor via valve 12 and line 5, returning condensed alcohol vapour to the column via line 11, withdrawing water from the base of the column via line 14, withdrawing a liquid mixture of alcohol and ester from the reactor via line 16 and separating the ester from the alcohol, the latter being returned to the column 8 via line 24. Specified acids are phthalic, sebacic, maleic, adipic stearic, isophthalic, terephthalic, isosebacic, specified anhydrides are phthalic and maleic and methanol is the specified alcohol. An esterification catalyst e.g. sulphuric acid or p-toluene sulphonic acid, may be used and is withdrawn from the reactor 2 with the ester and alcohol via line 16 and neutralised in vessel 17 with soda ash and discharged through line 19.  In a modification, alcohol vapour leaving the exchanger 4 is passed separately to the reactor 2 via line 25 (see Fig. 2) and the compressors 6 and 26 are so adjusted that the alcohol in the exchanger 4 from column 8 is kept at a pressure higher than that of the alcohol passed into the exchanger 4 via line 3. All water present in the wet alcohol is removed in column 8 by passing a sufficient quantity of alcohol back to the column via line 11.

Title: The separation of sulphur from solutions used in the removal of hydrogen sulphide from gases
Inventor: MILLS JOHN ERIC
IPC: C10K1/16
Filed: 1956-02-10
Abstract: <PICT:0827152/III/1> In a cyclic process for removing hydrogen sulphide from gases by alternate washing with a solution of an organic compound which will yield a readily oxidizable reduction product with H2S, and contacting the resulting solution with air or O2 to regenerate the original compound, the solution is passed through a cooled bed of S crystals at least at one point in the cycle.  Coal gas containing H2S1 enters an absorber via pipe 10 and flows counter-current to a stream of solution entering at 11.  The solution, consisting of a dye, e.g. methylene blue in a solvent, e.g. aniline, with a catalyst, e.g. pyridine or quinoline, after absorbing H2S, passes through a water-cooled bed of S crystals 14 where S from the solution is deposited.  The solution then passes to the oxidizer where it flows countercurrent to a stream of air or O2 entering at 15.  The regenerated solution is returned to the absorber via pipe 11 which may also or alternatively contain the sulphur bed as indicated. Specifications 827,151 and 827,154, [both in Group XII], are referred to.
