Patent GB-652766-A (GB)
Title: Surface coatings
IPC: C04B28/26
Filed: 1948-04-13
Abstract: Surface finishes of high reflectivity are given to articles and structures by applying an undercoating comprising a water-soluble silicate and a water-insoluble metal oxide, hydroxide or salt, drying the undercoating and then applying a coating comprising an aqueous solution containing calcium chloride.  The water-soluble silicate is preferably an alkali metal silicate such as sodium silicate and the metal compound may be an oxide, hydroxide, carbonate or phosphate of barium, calcium, magnesium, zinc, or lead or titanium dioxide, zinc sulphide or barium sulphate.  There may also be present in the undercoating a liquid synthetic resin and/or a metal salt of a higher fatty acid such as aluminium stearate, fillers, e.g. talc, an oil e.g. spindle oil, and a wetting agent, e.g. "Teepol" (Registered Trade Mark).  There may also be present in the second coating phosphoric acid, zinc chloride, magnesium chloride, aluminium sulphate, an alkyd resin containing abietic acid, magnesium and/or zinc fluosilicate, a silicon alcohol, a silicon ester and a resin, a partly hydrolysed silicon ester and a filler such as talc.  A third coating of a silicon ester with or without resin, a silicon alcohol or a partly hydrolysed silicon ester may be applied where the second coating does not contain one of these.  Both the undercoating and the second coating may be applied in one or more layers.  Particles of a water-insoluble reflecting crystalline solid with or without pigments may be incorporated in the undercoating and the surface abraded either before the second coating is applied or after it is dried to render the crystalline particles visible.

Title: Improvements in or relating to propellants and method of making the same
IPC: C06B21/00
Filed: 1954-04-08
Abstract: 756,771. Propellants. OLIN MATHIESON CHEMICAL CORPORATION. April 8, 1954 [June 9, 1953], No. 10345/54. Class 9(2) A propellant for cartridges larger than 0-30 in. is prepared by forming smokeless powder base into grains having a surface area 10-74 sq. cms. per gram, and web 0.015-0.070 in., and treating the grains with a non-migratory deterrent having a negative heat of explosion constant greater than -200 calories per grain, only in the region thereof which extends from each surface not more than 1/6th of the web of the grain. Deterrents, which may be present in amount 3-15 per cent, preferably 6-10 per cent or 9 per cent for 90 mm. propellant, may be dibutyl-, diamyl-, or diphenyl-phthalate, diethyl, methyl ethyl-, or dimethyl diphenyl urea, tricresyl or triphenyl phosphate, butyl stearate, butyl ricinoleate, or glycerol sebacate. The grains should be non-porous, i.e. have a specific gravity 1.5, and may be impregnated with 10-20 per cent liquid nitric ester of a polyhydric alcohol, e.g. nitroglycerin, befor deterrent treatment. In an example, nitrocellulose (13.2 per cent N 2 ) is suspended in water and agitated at 70‹C., after addition of ethyl acetate containing diphenylamine, until the nitrocellulose has dissolved. Agitation is continued while gum arabic dissolved in water, and then sodium sulphate dissolved in water are added, and finally solvent is removed by raising the temperature to 99 ‹C. The hardened globules are separated and suspended in water; an emulsion of nitroglycerine in ethyl acetate and water is added and the whole agitated, heated to 70‹C. and ethyl acetate removed by passing in air. An emulsion of dibutyl phthalate and gum arabic in water is added to the agitated slurry, and the grains are separated, compressed, and tumbled in a sweetie barrel with potassium nitrate, diphenyl phthalate, and dinitrotoluene, and finally with graphite. Alternatively, colloided nitrocellulose may be extruded and cut into grains. For U.5 in. cartridges the grains have surface 55-72 sq. cms./grm. and web 0.016-0.023 in. for 0.6 in. 45.60 sq. cms./grm. and 0.022-0.028 in., for 20 mm. 35-55 sq. cms./grm. and 0.025-0.032 in., and for 90mm. 32 sq. cms./grm. and 0.034 in.

Title: Manufacture of basic chromium sulphate free from iron and solutions thereof
IPC: C01G37/08
Filed: 1935-04-04
Abstract: In the removal of iron from solutions containing ferrous sulphate and chromium sulphate, a solution in which the basicity of the chromium sulphate is about 10 per cent and which contains 14,5 to 16 per cent of Cr2O3 is first obtained, e.g. from ferrochrome with adjustment of the basicity if necessary by addition of chromium hydroxide, a large proportion of the ferrous sulphate is crystallized out, and from the filtrate remaining iron is precipitated by means of b -naphthalene sulphonic acid. Prior to or following the precipitation step, chromium hydroxide may be added to increase the basicity of the solution to 33 per cent.
