Abstract: 535,824. Typewriters &c. NATIONAL CASH REGISTER CO. Oct. 19, 1939, No. 28213. Convention date, Nov. 19, 1938. [Class 100 (iv)] Paper-feeding arrangements.-To ensure uniform and straight feed of the paper by means of platen and co-operating feed-rollers, the feedrollers are driven through frictional connections at a greater surface speed than the platen. The feed-rollers 21, Fig. 1, are mounted on a shaft 15 and are frictionally coupled thereto by means of springs 22 which abut on adjustable collars 23. The shaft is mounted in spring-urged arms 16, 17 and is provided with a pinion 14 which meshes with a pinion 13 on the platen 10, the pinions causing the feed-rollers to have a slightly greater surface speed than the platen. The arrangement is particularly applicable for feeding a tally-strip 26.

Title: A process for the manufacture of waxes
IPC: C07C69/26
Filed: 1934-10-03
Abstract: In the catalytic reduction with hydrogen of fatty acids containing at least eight carbon atoms, esters are obtained as the principal products by adding to the catalyst, which may be any of the known hydrogenation or methanol-forming catalysts, a regulator consisting of a non-metallic compound containing a non-metal or metalloid of the fourth, fifth or sixth periodic group which is capable of exercising a higher valency; specified regulators are non-metallic compounds of di- or tetra-valent sulphur, non-metallic cyanogen compounds, carbon monoxide, and non-metallic compounds of trivalent arsenic and phosphorus.  When unsaturated fatty acids are treated, unsaturated esters are produced from which unsaturated alcohols are obtainable by saponification.  In the examples: (1) oleic acid is hydrogenated at 280 DEG  C. and above 200 atm. in the presence of a catalyst and a regulator both prepared as described below, this yielding a product of acid value 58,3, iodine value 5,6, hydroxyl value 0, and ester value 83,4; it is stated that, if the regulator is omitted, the product obtained under otherwise identical conditions has an acid value 4,2, iodine value 0,6, hydroxyl value 123,4, and ester value 33,3; (2) oleic acid is treated as in example 1 but in the presence of a higher proportion of regulator; the product has an acid value 42,7, iodine value 70,1, hydroxyl value 0, and ester value 76,9.  The regulator used in the examples is prepared by boiling sulphur in quinoline, whereby hydrogen sulphide is evolved, and diluting the product with xylene.  The catalyst used in the examples is prepared by precipitating copper carbonate from a solution of copper sulphate, boiling the washed precipitate in aqueous suspension with ammonium bichromate, and calcining the precipitate at 400 DEG  C. after rewashing and drying. Catalysts containing platinum, palladium, cobalt or nickel may also be used.ALSO:In the catalytic reduction with hydrogen of fatty acids containing at least eight carbon atoms, esters are obtained as the principal products by adding to the catalyst, which may be any of the known hydrogenation or methanol-forming catalysts, a regulator consisting of a non-metallic compound containing a non-metal or metalloid of the fourth, fifth or sixth periodic group which is capable of exercising a higher valency; specified regulators are non-metallic compounds of di- or tetra-valent sulphur, non-metallic cyanogen compounds, carbon monoxide, and non-metallic compounds of trivalent arsenic and phosphorus.

Patent GB-1072698-A (GB)
Title: Recovery of epoxy-alcohols
IPC: C07D301/06
Filed: 1964-07-10
Abstract: Substantially colourless epoxy alcohols are recovered from a crude oxidate by distilling said oxidate in a first column to recover unreacted olefin present as an overhead fraction, distilling the base product from the first column in a second column to recover a second overhead fraction comprising only monooxygenated compounds and epoxyalcohols and subsequently fractionating said second overhead fraction in at least one further column to recover the epoxy alcohols.  The crude oxidate is defined as that obtained by (1) liquid phase oxidation of monoolefins with molecular oxygen in the presence of a catalyst selected from the metals of Groups IVA, VA and VIA or their compounds, excluding Cr, or by (2) liquidphase autoxidation of monoolefins in a first stage, followed by re-arrangement of the hydroperoxides so formed in a second stage by treatment with a catlyst of the type used in method (1).  Both these methods give rise to coloured impurities comprising heavy, or high-boiling material and these impurities remain as a base product in the second column in the present process.  An example relates to the recovery of 3,4 - epoxy - 4 - methylpentanol - 2 and 3,4-epoxy-2 -methylpentanol-2.
Patent GB-957102-A (GB)
Title: Improvements relating to processes for the production of urea
IPC: C07C273/02
Filed: 1961-08-08
Abstract: Carbonyl sulphide for use in the production of urea (see Division C2) is obtained by reading carbon monoxide or a gas containing it with sulphur vapour at 300-700 DEG  C. for 1-20 seconds. The reaction may be carried out in a reactor filled with ceramic material, which may be coated with a heavy metal sulphide, such as molybdenum or tungsten sulphide, as catalyst, at 550-700 DEG C. for 5-20 seconds. The reaction is preferably carried out with more than a 25% excess of sulphur.  The small amount of CS2 in the reaction gas can be removed by washing it out with a suitable solvent or adsorbing it on activated carbon; or it may be removed by passage through a tower containing sulphur, sulphur for the reaction being taken from this tower and vaporized, addition of CO2 then converting the CS2 into COS.  The mixture of reactants can also be obtained by passing pre-heated CO-containing gas through liquid sulphur.ALSO:Urea is obtained by reacting carbon monoxide or a carbon monoxide-containing gas with sulphur vapour at 300-700 DEG C. for 1-20 seconds to obtain carbonyl sulphide COS, cooling, adding ammonia and passing the mixture at 60-100 DEG C. over activated carbon.  The first step may be carried out or reactor filled with ceramic material, which may be coated with a heavy metal sulphide catalyst, at 550-700 DEG C. for 5-20 seconds. The activated carbon in the second step may be stationary in one or more vertical towers, or may be moved countercurrent to the reactants. The urea deposited on the activated carbon may be dissolved in water and the solution concentrated to crystallise the urea.

Patent GB-288213-A (GB)
Abstract: 288,213. Consortium f³r Elektrochemische Industrie Ges. April 4, 1927, [Convention date]. Acetaldehyde; acetic propionic, butyric, and other acids; crotoraldehyde; adol; aldehyderesins.-Acetaldhyde is produced by decomposing a vinyl ester, for example, vinyl acetate, propionat,e, or butyrate with water, with the addition if desired of a substance having acid reaction to act as a catalyst, and a solvent or any emulsifying agent. The acid substances mentioned are phosphoric and sulphuric acids, and acid salts such as sodium dihydrogen phosphate and sodium bisulphate. The solvent may be the corresponding carboxylic acid, and the emulsifying agent may be used even in so small a proportion that homogenizing occurs only at boiling-point. It is preferred to remove the aldehyde as quickly as possible after its production to avoid undesired reactions, and an excess of water is employed to avoid the production of ethylidene ester which resinifies easily. The reaction may be effected in a column still or the like so that the reagents are continuously supplied, the acetaldehyde being continuously distilled off while the acid produced is continuously withdrawn. In the examples, vinyl acetate is treated with acetic acid and water and with phosphoric or sulphuric acid in various proportions. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of alkaline agents and of organic sulphonic acids or catalysts for the reaction, and the production of aldol, crotonaldehyde, or aldehyde resin when alkaline agents are employed. This subject-matter does not appear in the Specification as accepted.
