Abstract:
An aluminum-silicon alloy comprising aluminum as the principal metal, with silicon, magnesium and copper in substantial amounts and iron, titanium, magnesium and zinc in lesser amounts.
Abstract:
HETEROGENEOUS COMPOSITIONS, STABLE AGAINST SEDIMENTATION, ARE MADE BY SUSPENDING AN INSOLUBLE SOLID COMPONENT IN A LIQUID MIXTURE OF TWO COMPONENTS, ONE MORE AND THE OTHER LESS DENSE THAN THE SOLID COMPONENT, IN SUCH PROPORTIONS THAT THE DENSITY OF THE LIQUID MIXTURE APPROXIMATES CLOSELY THAT OF THE SOLID COMPONENT. EXEMPLARY COMPOSITIONS ARE SUSPENSIONS OF BERYLLIUM HYDRIDE IN (1) 82 VOLUME PERCENT PENTABORANE, 18 VOLUME PERCENT TRIMETHYLALUMINUM, AND (2) 93 VOLUME PERCENT PENTABORANE, 7 VOLUME PERCENT DECABORANE.
Abstract:
A process is disclosed for desulfurization of coal which comprises: digesting, in a digestion zone, coal and a Group IA or IIA metal oxide or mixtures thereof in the presence of a fused metal chloride salt medium, which medium is capable of dissolving sulfur-containing organic compounds present in the coal and which has a melting point below the digestion temperature; passing anhydrous hydrogen chloride into the digestion zone and removing from the digestion zone desulfurized coal. Subsequent refining of the desulfurized coal is also disclosed.
Abstract:
A method of improving the quality of the bones and/or increasing the bone strength of animals, including humans, cattle, sheep, goats, swine and poultry without deleterious effects on the animals or products of the animals by adding a small effective amount of zeolite to the feed of the animals or directly to the animals in the form of a capsule or tablet for example.
Abstract:
Titanium oxide containing concentrates are recovered from sand composed in the particle size range of 100 mesh and smaller of titanium oxides, heavy metal silicates, and silica. A plural stage flotation process is used. In the first stage the sand in the above size range is subjected to flotation using air and an anionic collector to yield a heavy mineral concentrate. The second stage flotation involves treating this heavy mineral concentrate with nitrogen and an anionic collector to float off the heavy metal silicates, the titanium oxide concentrate remaining in the tailings.
Abstract:
ZEOLITES IN POULTRY NUTRITION A method of improving the quality of egg shells of laying poultry or laying hens without deleterious effects on the contents of the poultry egg shells by adding a small amount of zeolite A to the feed of the poultry.
Abstract:
PROCESS FOR PREPARATION OF ORGANIC ACID HALIDE A process for the preparation of organic acid halide such as acetyl chloride by reacting an organic acid anhydride with a silicon halide, such as silicon tetrachloride, under conditions such that the organic acid halide is produced along with silica which is easily separated and disposed of. A Lewis Acid metal halide catalyst is used and superior yields are obtained. The reaction is desirably carried out in the presence of a chlorohydrocarbon solvent in which the metal halide catalyst chosen and the reactants and products are soluble.
Abstract:
ZEOLITES IN POULTRY NUTRITION Interior egg quality, usually expressed in Haugh Units, is prolonged by feeding the laying poultry a diet containing zeolite A. If the feed contains a reduced chloride content, egg shell quality, egg shell thickness or egg specific gravity may be also improved, and/or the number of shell-less eggs may be reduced.
Abstract:
ZEOLITES IN POULTRY FEEDING A method of improving the lean/fat ratio in broiler poultry by adding a small effective amount of zeolite A up to four weight percent of the feed, to the feed of the broiler pultry and regularly feeding the broiler poultry the feed containing the zeolite A.
Abstract:
IMPROVED PROCESS FOR PRODUCING MAGNESIUM UTILIZING ALUMINUM METAL REDUCTANT Magnesium metal is produced by the reaction of aluminum metal with a calcium magnesium aluminate slag or with magnesium oxide in the presence of such slag, wherein the silicon dioxide content of the slag is maintained at five weight percent or less. An excess of aluminum metal relative to the amount of magnesium oxide is employed thereby obtaining a high conversion of the magnesium oxide to magnesium metal.
