Title: Thiolation of polymers
IPC: A61K8/64
Filed: 1961-02-09
Abstract: A process for the thiolation of a polymer containing at least one free amino group, particularly a protein or enzyme, comprises treating the polymer with a thiolactone dissolved or dispersed in a polar reaction medium, particularly water, at a pH maintained by a tertiary amine above the pK value of the amino group or groups in the polymer.  The polymer may be gelatin, casein, papain, yeast ribonucleic acid, deoxyribonucleic acid or animal glue.  The thiolactic may be N-acetyl homocystein thiolactone, beta, gamma or delta thiovalero- or thiocapryl lactone, or beta or gamma thiobutyrolactone.  The tertiary amine may be trimethylamine, triethylamine, diethylethanolamine, N-methyl piperidine or N-methyl morpholine.  The thiolated polymers may be cross-linked by oxidation conversion of the thiol groups to disulphide bonds.

Title: Improved compositions comprising asphalt emulsions and products made therefrom
IPC: C08L95/00
Filed: 1932-02-18
Abstract: Viscous compositions are obtained by mixing together an asphalt emulsion and a dispersion of vulcanized or unvulcanized rubber, guttapercha, or balata, the minimum degree of concentration of each constituent being 40 per cent.  Preferably the rubber dispersion has a concentration of 60-70 per cent and the asphalt emulsion contains 65 per cent of asphalt.  If weaker emulsions of asphalt are used it is desirable to add viscosity-increasing ingredients such as bentonite, casein, leico gum, and water-glass. Protective colloids, vulcanizing agents, &c. may be added to the rubber dispersion.  The compositions may contain 5-40 per cent of rubber calculated on the asphalt content.  They may be used for impregnating or coating, or mixed with aggregates or fillers for covering roads or moulding into slabs &c.ALSO:Viscous compositions are obtained by mixing together an asphalt emulsion and a dispersion of vulcanized or unvulcanized rubber, guttapercha, or balata, the minimum degree of concentration of each constituent being 40 per cent.

Patent GB-719647-A (GB)
Title: Shaving creams
IPC: C11D17/00
Filed: 1952-02-28
Abstract: A shaving cream suitable for packaging under pressure in an aerosol dispenser comprises a detergent consisting of water-soluble fatty acid soaps of sodium, potassium and at least one nitrogen-containing base, the fatty acids from which these soaps are derived having 12-20 carbon atoms in the molecule, a liquefied normally gaseous low molecular weight halogenated hydrocarbon propellant, and an aqueous solvent medium in which the detergent is at least partly dissolved, the propellant and any undissolved detergent being dispersed in the solvent medium.  The nitrogen-containing base may be ammonia or triethanolamine.  The concentration of detergent in the cream is usually 5-15 and preferably 5-10 per cent. by weight.  The ratio of the nitrogen-containing soap to the sum of the alkali metal soaps should preferably be within the range 1.2 : 1 to 2.5:1.  The alkali metal soap component should contain at least 3.5 times as much potassium soap as sodium soap.  The aqueous solvent medium may be plain water or water containing a small proportion of methanol, ethanol or normal or isopropanol and may constitute 70-90 and preferably about 80 per cent. by weight of the cream. The propellant may be mono-chloro-difluoro-methane or -ethane, dichloro-monofluoroethane, dichlorodifluoro- or trichloromonofluoro-methane, or dichloro-tetrafluoro- or difluoro-ethane or may be a mixture of two or more such compounds. The cream may contain 5-15, preferably 7-10, per cent. by weight of propellant.  In an example about 3.5 parts by weight of triethanolamine stearate, about 1 . 1 parts of potassium stearate and about 0 . 3 parts of sodium stearate are dissolved at about 130 DEG F. in about 90 parts of deionized water, and the solution is cooled about 90 DEG F. and introduced into the pressure container of an aerosol dispenser.  The contents are cooled to -5 DEG F. and about 5.5 parts of a cooled and liquefied propellant comprising about 60 per cent. dichloro-tetrafluoroethane and 40 per cent. dichloro-fluoromethane are added, and the container is sealed and shaken to disperse the propellant in the mixture.  In other examples shaving creams are similarly prepared and packaged using soaps of palmitic acids, of palmitic and stearic acids and of stearic acid and coconut oil fatty acids respectively.  In one example lauryl diethanolamide is added as a lather stabilizer, and in others lanolin and lecithin, glycerine, borax and sodium silicate, or isopropanol, glycerine and stearyl diethanolamide respectively are used as adjuvants.  Those silicates, phosphates, nitrites, benzoates or borates known to act as corrosion inhibitors may be incorporated in the cream.

Title: Improvements in and relating to the dyeing of alginate fibres
IPC: D06P3/00
Filed: 1943-04-02
Abstract: The dyeing properties of alginate fibres, e.g. of calcium, chromium or beryllium alginate fibres, are improved, especially in respect of their dyeing with direct cotton, acid and mordant dyes, by treatment, prior to the dyeing operation, with a solution in acid of the product obtained by interaction of cyanamide with formaldehyde. Advantageously, such treatment is effected in conjunction with a treatment with a solution of a copper salt to enhance the fastness of the dyeings to light.  In examples: (1) calcium alginate fibres are treated for 20 minutes with an aqueous solution at 60 DEG  C. containing acetic acid and a condensation product obtained by adding aqueous formaldehyde to an aqueous solution of cyanamide, making slightly alkaline with caustic soda and filtering off, washing and drying the precipitate, whereupon the treated fibres are rinsed and dyed with Chlorazol fast red K from an aqueous bath at 90 DEG  C. containing common salt; (2) calcium alginate fibres are similarly treated with an addition of copper acetate to the treatment liquor, rinsed and similarly dyed with Chlorazol sky blue FF; beryllium alginate fibres are treated as in (1) and similarly dyed with Pyrazol orange G; (4) chromium alginate fibres are treated as in (1) and similarly dyed with Chlorantine fast blue GLN; (5) calcium alginate fibres are treated as in (1) and dyed with Coomassie navy blue 2RNS from an acetic acid bath; (6) beryllium alginate fibres are treated as in (1) and dyed with Elite fast red R from an acetic acid bath; (7) chromium alginate fibres are treated as in (1) and dyed as in (5); (8) calcium alginate fibres are treated as in (1), mordanted with an aqueous solution containing sodium bichromate and formic acid, washed and dyed with Alizarine red S from an acetic acid bath; (9) beryllium alginate fibres are treated as in (1) and dyed with Neolan blue 2G from a bath containing formic and tannic acids; (10) chromium alginate fibres are treated as in (1) and dyed with Alizarine red S from an acetic acid bath, with or without a preliminary mordanting as in (8).
