Title: Improvements in treating fabrics, or other materials
IPC: D06P1/44
Filed: 1952-08-18
Abstract: Fabrics, fibres and yarns are coated with an aqueous resin emulsion comprising a latex of an organophilic thermoplastic resin, e.g. polymethyl methacrylate or a copolymer of butadiene - acrylonitrile, styrene - butadiene, vinyl chloride - vinylidene chloride or vinylidene chloride-acrylonitrile, stabilized by a minor proportion of a water-soluble soap, e.g. sodium oleate or other sodium, potassium or ammonium soap of a fatty acid as a suspension agent, and the coating is set by exposure to acid vapours.  The vapours, which may be hydrochloric or sulphuric acid but are preferably acetic acid or a mixture of formic and acetic acids, react with the soap, and the coating may then be heat-cured.  The fabrics may include fibres of a vinyl chloride-acrylonitrile copolymer or other acrylic copolymer or of cotton, rayon or acetate rayon.  Additional components of the emulsion may be salts of copolymers of styrene with an acid ester of a polymerizable polycarboxylic acid, e.g. the partial butyl ester of maleic, itaconic, or fumaric acid, pigments, e.g. phthalocyanine blue or green or carbon black; thermosetting resins, e.g. butylated melamine, triazine, and urea-formaldehyde resins, unalkylated urea-formaldehyde resin, sulphonated phenol-formaldehyde resin or an alkyd resin.  Examples show the preparation of emulsions and their application.  Specification 735,051 is referred to.ALSO:An aqueous resin emulsion comprising a latex of an organophilic thermoplastic resin, e.g. polymethyl methacrylate, and butadiene-acrylonitrile, styrene-butadiene, vinyl chloride-vinylidene chloride and vinylidene chloride-acrylonitrile copolymers, stabilized by a minor proportion of a water-soluble soap, e.g. sodium oleate or other sodium, potassium or ammonium soap of a fatty acid, as a suspension agent, is coated on a fabric and set by exposure to acid vapours.

Title: Improvements in methods of influencing the combustion of ignition compositions, explosives and the like
IPC: C06B43/00
Filed: 1929-07-11
Abstract: 333,364. Stephens, A. J., (Asociacion de Productores de Yodo de Chile). July 11, 1929. Matches; striking-surfaces.-Iodine or an iodine compound, especially cuprous or plumbous iodide, is added to igniting compositions containing oxidizable substances such as chlorates, nitrates,and peroxides; or the iodine or iodine compound is added to the rubbing surface used for igniting compositions. This improves ignition or combustion. One example of igniting composition contains 50.52 per cent of potassium chlorate, 3-4 per cent of potassium bichromate, 5 per cent of sulphur or minium (Pb3O4), 10 per cent of iron oxide, 10 per cent of manganese peroxide, 10-12 per cent of quartz or glass powder, and 10-12 per cent of glue, to which 1-2 per cent of cuprous iodide is added. One example of rubbing surface relates to a mixture of 50 per cent of red phosphorus, 10 per cent of antimony sulphide, 17 per cent of kieselguhr, 5 per cent of whiting, and 18 per cent of gum arabic, in which the 50 per cent of red phosphorus is replaced by 10 per cent of red phosphorus with 5 per cent of cuprous iodide, the proportions of the other ingredients being proportionately increased. A similar effect is obtained by the addition of 1-2 per cent of cuprous iodide to potassium chlorate or perchlorate, such addition causing these salts to give up the whole of their oxygen content uniformly when heated below 300‹ C. instead of the 400‹ C. required when no such addition is made.
