Patent GB-343577-A (GB)
Title: Improvements in or relating to the manufacture of amidines
Filed: 1929-11-22
Abstract: Hydroxy-aralkylamidines are made by causing a hydroxy-aralkylcyanide to react with alcohol and hydrochloric acid gas to form the corresponding iminoetherhydrochloride and treating the resultant product with ammonia or a primary or secondary amine.  In the example, p-hydroxybenzylcyanide and absolute ethyl alcohol are dissolved in dry benzene and then saturated with dry hydrochloric acid gas.  After standing in the cold, crystals of p-hydroxyphenylacetiminoether hydrochloride separate out and these are then treated with dry alcoholic ammonia when the p-hydroxyphenylacetamidine hydrochloride gradually crystallizes out. The amidines possess therapeutic properties.

Patent GB-1508255-A (GB)
Title: Timepiece movement
IPC: G04C3/14
Filed: 1976-08-31
Abstract: A small sized electric timepiece movement has a radius which is less than the diameter of the battery which powers the movement. Hence, the battery extends from one side of the movement to a point beyond the centerline of the timepiece. Advantage is taken of the fact that the battery is dome-shaped so as to accommodate a portion of the base plate which rotatably supports the cannon pinion and hour wheel of the timepiece movement which are located centrally of the timepiece. Hence, the axis of the cannon pinion and hour wheel, if projected, would intersect the battery. The invention enables the construction of an electronic timepiece which is smaller than would otherwise be possible. With a battery having a diameter of 7.9 mm and a thickness of 3.5 mm, it is possible to make a timepiece having a diameter of 14.8 mm and a thickness of about 4 mm.

Title: An improved method of producing coloured photographic materials
IPC: B01D53/26
Filed: 1933-12-28
Abstract: 430,991. Colour photography; colour filters. GASPAR, B., 38, Innsbrucker Strasse, Schoneberg, Berlin. Dec. 28, 1933, No. 36491. Convention date, Dec. 29, 1932. [Classes 97 (i) and 98 (ii)] Coloured photographic images or layers are produced by incorporating hydrazo substances or their derivatives in the photographic or image - bearing layer and subsequently converting them to dyestuff. The hydrazo compounds may be incorporated in the emulsions or in the layer after exposure, by bathing, or in the emulsion before application to the support. A finished silver image may be immersed in a solution of a hydrazo compound which is then converted diffusely into an azo dyestuff, the dyestuff being subsequently destroyed locally at the image or non-image positions, e.g. as described in Specifications 395,718, 397,159, 397,188, and 397,192. Alternatively, the dyestuff may be produced locally by converting the silver image into an oxidant, e.g. lead chromate ; or the hydrazo compound may be locally destroyed at the image points with slightly acidified thiocarbamide, the remaining hydrazo compound being subsequently converted to dyestuff. Multicolour photographs may be produced by combining particles of emulsion of different colour-sensitiveness with different hydrazo compounds in the manner of multicolour screen images, with or without filter dyestuffs ; or by the use of multi-layer material containing appropriate hydrazo compounds in the different layers. Specified hydrazo compounds are benzene hydrazo-alpha-naphthol, hydrazobiphenyl and hydrazoines. Insoluble salts of hydrazo compounds, e.g. hydrazo aryl, sulphonic acids with salts of nitrogenous organic bases may also be employed. Suitable oxidizing agents are ferric chloride and nitrous acid. Colour filters may be produced by treating the layer to form a diffuse silver image and converting this into a diffuse dyestuff deposit.
Patent GB-643852-A (GB)
Title: Improvements in or relating to the production of soap
IPC: C11D13/02
Filed: 1946-12-11
Abstract: Millable soap is produced directly by the saponification, by means of alkali, of soap-forming fatty acid esters of such alcohols as have a boiling point below 100 DEG  C. at normal atmospheric pressure, the saponification being carried out, in the presence of a liquid diluent for the soap, at a temperature at which the charge is from semi-liquid to liquid and above the boiling point of the alcohol liberated from the esters but not exceeding 125 DEG  C.  The diluent, consisting of water and/or an alcohol normally boiling below 100 DEG C., is volatile at the pressure and temperature prevailing during the saponification and has a boiling point above that of the alcohol liberated from the esters.  The latter alcohol and part or all of the diluent are distilled off, the resultant vapours fractionated so as to separate the ester alcohol from the diluent and the latter is returned as a reflux continuously to the soap mass.  The amount of diluent originally present in the saponification mixture is so adjusted that the proportion of diluent remaining after saponification is such that the soap mass on cooling is directly millable.  The diluent, when consisting of water, may be added in such proportions that the residual moisture content after saponification is 10-30 per cent and preferably 10-20 per cent. The saponification may be carried out in a still provided with agitating means and with a fractionating column designed to return the reflux comprising the diluent continuously to the still. Free fatty acids may be added towards the end of the saponification process for the purpose of neutralizing any excess of alkali.  In the event of a small proportion of the diluent being distilled off with the alcohol liberated from the ester as may occur if the soap is completely freed from such alcohols, this loss may be made good by the addition of a corresponding amount of water to the mass towards the end of the saponification process. The caustic alkali used for the saponification may be added either at once at the beginning or in stages during the process.  The alkali may be added in solid form or as a concentrated aqueous solution, the water content of which is allowed for in adjusting the total amount of diluent required.  The saponification may be carried out at atmospheric or at higher or lower pressure.  In the example, 1000 kg. of methyl esters of mixed palm oil fatty acids are heated and stirred with 152 kg. caustic soda and about 100-200 kg water at 120-125 DEG  C.  The methanol liberated from the p  ester is distilled off through a fractionating column while the water is returned as reflux to the saponification vessel. Specification 571,145 and U.S.A.  Specification 2,084,446 are referred to.

Title: Production of detergent alkylate
Inventor: HABESHAW JOHN
IPC: C07C1/36
Filed: 1961-10-13
Abstract: Detergent alkylate is produced by alkylating benzene in the presence of aluminium chloride or hydrogen fluoride with olefins obtained by oxidizing paraffins in the C10-C17 range containing at least 95% normal paraffins in the presence of boric acid to obtain borate esters of secondary alcohols and thermally decomposing the esters to olefins.  Oxidation is effected at 100-300 DEG C. in the liquid phase restricting the conversion to below 40%.  The esters are decomposed at 200-450 DEG  C. and prior or subsequent to this step unreacted paraffins are separated by distillation, purified of oxygen compounds by treatment with sulphuric acid and recycled.  Alkylation is conventional and the product is distilled to separate benzene for recycle, detergent alkylate and heavy alkylate.
