Abstract: A new dry phosphoric acid product and the process for making it are disclosed. The product is a dry finely divided, brown or black, charcoal-like, extremely hygroscopic powder having an effective phosphoric acid content of up to about 122.4% by weight (based on a 75% aqueous solution) a phosphorus content of up to about 29% by weight; and a moisture content usually less than 10% by weight, typically 3 to 8%. The product is useful as a source of phosphoric acid, and in combination, it produces a new animal feed ingredient material, a new drilling mud additive, and other novel products. The process comprises first mixing a phosphoric acid solution, such as 75 or 85% by weight phosphoric acid solutions of commercial grade, with a dry, relatively fine absorbent material, preferably an organic absorbent material such as peanut hulls, rice hulls, beet pulp or other inexpensive organic by-products, and then drying the mixture in conventional drying equipment, preferably at temperatures from 150.degree. to 200.

Abstract: A process for imparting a positive electrical charge to a gaseous stream comprises contacting the stream with an aqueous solution comprising about 500-3000 ppm of a composition consisting essentially of borax and a surfactant. In the composition, borax and the surfactant are present in a weight ratio of borax to surfactant of about 1.2:1 to about 15:1. The process and composition are useful in the control of static electricity.

Abstract: Gel-like composition useful for separating and partitioning whole blood into serum and clot portions. The composition has a specific gravity between that of the serum and clot portions such that, when centrifuged in the presence of whole blood, the composition forms a chemical and physical barrier between the serum and clot portions. The composition comprises, in combination, a silicone fluid, an inert siliceous filler dispersed therein, and a network former consisting of a polysiloxane-polyoxyalkyl copolymer which stabilizes the composition by minimizing and/or avoiding "wet out" of the siliceous filler with time. The composition has a viscosity within the range of about 200,000 to about 600,000 centistokes, preferably within the range of about 350,000 to about 450,000 centistokes.

Abstract: The reaction product of a hydroxy ether and a pentavalent phosphorous compound with a short chain and/or long chain alcohol can be employed to reduce friction loss of organic liquids flowing through a confining conduit by mixing the reaction product with the organic liquid in the presence of a basic multivalent metal salt activator.

Abstract: A method for achieving acetylene gas mixtures which can be stored safely in increased quantities in closed containers, with undiminished safety, is provided.

Abstract: Methods of preparing fluid mixtures in a chamber under close temperature and pressure controls in which liquid water is introduced into the chamber along with gases selected from the group consisting of oxidizing and reducing gases for providing in the liquid water a mixture of carbon dioxide, hydrogen and carbon monoxide, and of oxidizing and carburizing gases for providing in the liquid water a mixture of carbon dioxide, methane, hydrogen and carbon monoxide under reaction conditions. The liquid water in the chamber is maintained under close temperature control of from about 32.degree. F. to about 160.degree. F. and gases in the chamber are maintained under control pressures from ambient atmospheric up to 218.5 atmospheres so that a saturated fluid mixture is generated having predetermined properties as determined by the controlled temperatures and pressures.

Abstract: An azeotropic composition made up of about 82.5 mol percent fluorotrichloromethane and about 17.5 mol percent 1,1,1,3,3,3-hexafluoroisopropyl trifluoroacetate, said composition boiling at about 22.degree. C at about atmospheric pressure. This composition can be fractionally distilled from a crude mixture so as to separate the components from the mixture.

Abstract: An immersion oil for microscopy is produced by blending 10 to 90 parts by weight of chain hydrocarbon having 200 to 5,000 of molecular weight and 10 to 90 parts by weight of specific diphenylmethane derivatives or bis(.alpha.-alkylbenzyl) alkylbenzene derivatives or 2,4-diphenyl-4-dimethylphenylbutane derivatives.The product obtained has excellent values in the various properties such as light dispersion, refractive index, viscosity and the like. Furthermore, it has an excellent advantage that the properties such as Abbe's number and the like are easily adjustable.

Abstract: This invention relates to the retardation of evaporation of ammonia and amines from essentially aqueous solutions by admixture thereto of an alkyl ether having the formula:R -- (0[CH.sub.2 ].sub.y).sub.n --R', wherein R is an alkyl group containing from 8 to 30 carbon atoms, and R' is an --OH or --NH.sub.2 group, y is an integer of 2 to 4, and n is an integer of 1 to 10.

Abstract: In the pack diffusion coating of chromium into the surface of a superalloy, the formation of undesirable oxide inclusion is reduced when the diffusion coating pack contains at least about 3% Ni.sub.3 Al. Also the formation of alpha-chromium is reduced when the pack diffusion is carried out in a retort effectively not over five inches in height. Pack aluminizing in the presence of chromium makes a very effective aluminum-and chromium-containing top coating over platinum plated or platinum coated nickel-base superalloys. Aluminized nickel can also have its aluminum attacked and at least partially removed with aqueous caustic to leave a very highly active catalytic surface. Pack diffusion can also be arranged to simultaneously provide different coatings in different locations by using different pack compositions in those locations. An aluminizing pack containing a large amount of chromium provides a thinner aluminized case than an aluminizing pack containing less chromium, or less chromium and some silicon.

Abstract: Disintegration of tablets is improved by the incorporation therein of a plurality of small tubules. The tubules can be prepared by subdivision of hollow fibers such as cellulose or cellulose acetate hollow fibers having inside diameters on the order of 50-300 microns into segments 100-1000 microns in length. Tablets and methods for their preparation are disclosed.
