Patent GB-747609-A (GB)
Title: Process for condensing aromatic sulphonic acids with aldehydes and other substances
IPC: C07G99/00
Filed: 1952-08-27
Abstract: Synthetic tanning agents are obtained by condensing an incompletely etherified ureathiourea- or melamine-aldehyde condensation product with an aromatic sulphonic acid.  The etherifying alcohol may be butanol, octanol, glycol, a polyglycol, glycerol or a monohydric poly-ether alcohol from the condensation of ethylene oxide with an alcohol.  Aldehydes specified are formaldehyde and acetaldehyde. Specified sulphonic acids are naphthalene sulphonic acid, phenol, cresol and naphthol sulphonic acids, sulphonated phenol-aldehyde condensation products, lignin sulphonic acids and alkylnaphthalene sulphonic acids.  Other unsulphonated condensable substances may be included in the condensation such as phenols, urea, thiourea, phenolaldehyde condensation products and o- or p-hydroxybenzoic acid. In an example a urea-formaldehyde condensate is partly etherified with glycerol and the product condensed at 90-95 DEG  C. for four hours with the product obtained by sulphonating naphthalene at 95-100 DEG  C. for 2 hours with concentrated sulphuric acid.  The final product is neutralized with ammonia and acidified with formic acid. The tanning agent may also be buffered or modified by addition of chromium or aluminium hydroxides.
Patent GB-731447-A (GB)
Title: Improvements in or relating to the production of modified alkyd resins
IPC: C08G63/48
Filed: 1952-08-27
Abstract: A modified alkyd resin is made by mixing and if desired heating together (1) a low molecular weight polymer or copolymer of a monohydric alcohol ester of acrylic acid and/or its alpha-substitution products; and (2) a mono- or diester of a fatty oil acid and a polyhydric alcohol, adding while the mixture is still unhomogenous (3) one or more polycarboxylic acids or anhydrides, and heating the resultant mixture.  The polymers (1) must have a specific viscosity divided by concentration in grms./litre measured in chloroform at 20 DEG  C. of below 0.02.  The polyhydric alcohol used in making reactant (2) is one containing three or more hydroxy groups (e.g. glycerol, 1,2,4-butanetriol or trimethylol propane) or a mixture of a dihydric alcohol (e.g. glycol) with one containing more than three hydroxy groups.  The resins are soluble in aromatics (e.g. xylene or benzol), esters of mono- and poly-hydric alcohols (e.g. ethyl acetate) and ketones, are compatible with basic pigments (e.g. zinc white) and with nitro-cellulose, and may be emulsified, used for surface coating, or as embedding material for reflecting substances in the production of reflection coatings.  In examples (1) polymethyl-methacrylate is mixed with linseed oil monoglyceride. To the unhomogeneous mixture, immediately or after heating to 220 DEG C. and cooling to 120 DEG  C., is added phthalic anhydride and lead oxide and the mixture heated for 10 hours up to 270 DEG  C.  (2) Polymethyl-methacrylate, a butanetriol partial ester of linseed fatty acids and maleic anhydride are reacted in presence of calcium linoleate as in (1).  (3) Polybutyl-methacrylate, the monoglyceride of dehydrated castor oil, phthalic anhydride and maleic anhydride are reacted as in (1).  The product may be used for embedding glass pearls.  (4) Polyethylacrylate is heated with the monoglyceride of linseed stand oil for 2 hours in presence of lead oxide.  Then phthalic anhydride is added and the mixture heated for 10 hours up to 270 DEG  C.  A solution of the product in ethyl acetate may be emulsified.  (5) A copolymer of the methyl ester of methacrylic acid and the ethyl ester of acrylic acid is heated with the diglyceride of dehydrated castor oil and the monolinoleate of trimethylol propane for 2 hours at 140 DEG  C.  Then phthalic anhydride is added and the mixture heated in presence of lead oxide.

Title: Method for setting keratin fibers in the form of yarn, fabric and garments
IPC: D06M11/05
Filed: 1964-05-27
Abstract: Wool fibres in the form of yarns, fabrics or garments in a desired shape e.g. stretched and/or flattened and/or on a former, beam or bobbin, pleated or folded, are permanently set (40 - 100%) without use of chemical setting and/or swelling agents. The fibres, in such shape and having a moisture content of 10-30% (calculated on the dry weight of the fibres) are maintained in an enclosed space e.g. an autoclave, under steam pressure at a temperature of 101 - 180 DEG C for a minimum period of time, varying inversely with the temperature, of from twenty minutes to two seconds.  Partial water vapour pressure is maintained in the space in equilibrium with partial water vapour pressure in the interior of the fibres so that the latter is maintained constant during the heat treatment.  A fabric may be maintained stretched in a direction at right angles to a desired direction of stretchability during the setting heat treatment. Stretch yarn is produced by twisting a single or plied yarn, setting the twist by the heat treatment and back-twisting.

Abstract: 479,861. Oil engines. BOXAN, W. Aug. 12, 1936, No. 22259. Convention date, Aug. 12, 1935. [Class 7 (iii)] Part of the air forced from the cylinder space into a precombustion chamber 2 enters with an axial movement through a central passage 6 and the remainder is given a rotating movement as it enters through helical passages 7 at the periphery of the chamber. An injector 12 delivers fuel jets 14 which penetrate both the axial and rotating parts of the air. and may deliver a jet 16 towards the passage 6. To reduce the throttling effect of the passage 6 during the inflow into the chamber, its end 9 is rounded off; the throttling effect of the passages 6 during the outflow is similarly reduced by rounding the ends 8 of the passages 7. In a modification, the passages 6, 7 are formed in projecting ribs 19, 18, Fig. 4, in an insertion which forms the bottom, of the precombustion chamber. In another modification, the bottom of the precombustion chamber is arched towards the injection nozzle and the jet 16 is delivered through the central passage into a cavity in the piston.

Abstract: Vat dyes, dyeing with; cellulose esters or ethers, dyeing.--Textile materials in package form, made of or containing cellulose esters or ethers, are dyed with vat dyes by passing through the packages an aqueous liquid containing a free leuco compound of the vat dye (cf. Specification 341,408) or a salt thereof and containing a water-soluble non-alkaline organic liquid and thereafter oxidizing the leuco compound on the materials. The non-alkalineorganic liquid is preferably one of a boiling point below 150 DEG  C., specified liquids being methyl, ethyl, propyl and isopropyl alcohols, acetone and methyl ethyl ketone.  The usual caustic alkali used to form a salt of the leuco compound and to provide the alkalinity of the vat may be replaced, wholly or in part, by weaker alkali, such as ammonia, methylamine, ethanolamines, propanolamines, benzylamine, cyclohexylamine, dimethylcyclohexylamine, pyridine, alkylpyridines or alkali salts of phenols (cf. Specification 262,506, [Class 15 (ii)]) or alkalinity of the vat due to caustic alkali may be reduced by addition of either salts of weak bases such as ammonia or an amine or weakly acid or salt-forming substances such as phenols, sugars or amino-acids, e.g. protein degradation products.  In examples cellulose acetate yarn in the form of wound bobbins is dyed by circulating through it (a) an aqueous liquor at 50 DEG  C. containing Ciba blue 2B, isopropyl alcohol, caustic soda, sodium hydrosulphite, turkey red oil and ammonia, with or without an addition of gelatine, or (b) a similar liquor in which the dyestuff is Caledon jade green G, or (c) a similar liquor in which cyclohexylamine is used in place of caustic soda, and thereafter circulating through it an aqueous solution containing soap, hydrogen peroxide and ammonia, washing and drying.
