摘要： 546,387. Refractory substances. TITANIUM ALLOY MANUFACTURING CO. Jan. 9,1941, No. 336. Convention date, Jan. 25, 1940. [Class 22] A mouldable composition for forming refractory articles is obtained by milling zircon with water, neutralizing, drying, mixing with not more than 17 c.c. of water per 100 grams of zircon and converting water-soluble calcium and aluminium salts in the mixture into insoluble crystalline precipitates having a water solubility not greater than 0.01 gram per 100 c.c. of water. Oxalic acid, tartaric acid, tetrasodium pyrophosphate, hexasodium metaphosphate may be used ; if oxalic acid is used, a small amount of gelatine or boric acid is added to prevent oxalic acid drying on the surface. Small amounts of aluminium silicates or magnesium silicates, such as clays, kaolins, mullites, sillimanites, bentonites, talc, calcium zirconium silicate, sodium fluosilicate and Portland cement may be added to the composition.

摘要： 544,628. Refractory substances. TITANIUM ALLOY MANUFACTURING CO. March 28, 1941, No. 4233. Convention date, April 18, 1940. [Class 22] Zirconium dioxide is prepared in plastic form suitable for slip casting by mixing the ground material with 0.01 to 0.2 per cent. of a pyrophosphate of a formula falling between M 4 P 2 O 7 and M 6 P 4 O 13 where M is an alkali metal, or with a mixture of pyrophosphate and a low melting-point glass. A small addition of bentonite, sodium silicofluoride, silicate or alginate, plaster of Paris, gelatine, a watersoluble gum such as gum arabic, gum tragacanth or dextrin, boric acid or borates may be made. The compositions are moulded, dried and fired at 2400-2600‹ F.

摘要： 536,857. Denture and like moulds. TITANIUM ALLOY MANUFACTURING CO. March 27, 1940, No. 5541. Convention date, March 31, 1939. [Class 22] Refractory moulds for casting metal articles such as dentures contain a material which will expand at high temperature as the result of oxidation such as carbon or nitrogen containing compounds of zirconium, titanium, thorium, cerium, hafnium and silicon. Examples of compounds are the carbide, nitride, oxycarbide or cyanonitride of zirconium, the carbide, nitride or cyanonitride of titanium, the carbide of silicon, thorium, cerium or hafnium or the nitride of thorium or hafnium. The amount of the expanding material added is regulated by the amount of expansion desired. A small amount of an oxidizing agent such as red lead or lead peroxide may be added. Impurities such as carbon, carbides of the alkali or alkaline earth metals and iron compounds should be removed by acid leaching. The refractory material used may be zircon, aluminium oxide. silica, quartz, rutile. fused zirconium dioxide, mullite, sillimanite, olivine, forsterite, chromite, refractory clay, kaolin, beryl, spinel, kyanite, thorium oxide, thorite, ceria, feldspar, andalusite, talc, baddeleyite, or porcelain and a bonding agent such as magnesium zirconate, phosphoric acid or water may be used.

摘要： 536,740. Cellulose-derivative and syntheticresin compositions ; films. TITANIUM ALLOY MANUFACTURING CO. Dec. 28, 1939, No. 33003. Convention date, Jan. 21. [Classes 2 (ii) and 2 (iii)] [Also in Groups III and XI] A composition capable of being formed into a sheet or film having the property of reflecting yellow light and transmitting blue light, is made by dispersing in a transparent or translucent base material (consisting of a synthetic plastic) a percentage, which is inversely proportional to the thickness of the sheet or film to be formed and is between 0.03 and 0.4 per cent. by volume for a sheet or film 1 mm. in thickness, of a white pigment in the form of particles of a substantially uniform size between 0.4 and 0.6 micron and of isomettic, tetragonal, orthorhombic or hexagonal crystal form and having a refractive index substantially different from that of the base material. Specified plastic base materials are synthetic resins of a phenolic, acrylic, styrene, poly-styrene or urea-formaldehyde base and cellulose nitrate, acetate and xanthate, and specified pigments are cerium dioxide, tin oxide, zirconium dioxide, titanium dioxide, thorium dioxide, antimony oxide, columbium oxide, tantalum oxide, and mixtures or combinations of these oxides with barium sulphate, calcium sulphate, zinc oxide, lithopone and fluorspar. A pigment in suitable form may be prepared by reacting a mixture of zirconium dioxide and soda ash at a temperature between 1660‹ and 1700‹F. until the zirconia grains peptise to form, as nuclei, uniform particles of less than 0.2 micron in size, which are then allowed to grow to the required size, as determined by periodic microscopic examination, the calcine being then cooled, treated with hydrochloric acid, digested with water, washed and dried.

摘要： 535,011. Vitreous enamels. TRIGGS, W. W. (Titanium Alloy Manufacturing Co.). June 19, 1939, No. 17824. Drawings to Specification. [Class 56] [Also in Group III] Zirconium oxide produced, as described in Group III, may be mixed with a small amount of an alkali metal compound, and roasted at 800-950‹C. to form a crystalline zirconium oxide, pure white in colour, having particle sizes chiefly between 0.40 and 3 microns, such a product having good opaquing effects when used in enamels and glazes. Examples are given.
