Abstract: A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on a liquid mixed isopropylphenyl/phenyl phosphate ester and contains small amounts of an amine selected from the group consisting of phenyl-.alpha.-napthyl-amine, phenyl-.beta.-naphthylamine, and diphenylamine; benzotriazole, and a corrosion inhibitor selected from the group consisting of oleylsarcosine, epoxidized soybean oil, and a mixed mono- and dialkyl phosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms.

Abstract: Polyurethane polymers characterized by a molecular weight above 6,000 and having lactone groups and hydroxyl groups in the polymer backbone are prepared by reacting a mixture of polyglycols proportioned so as to provide the desired polymer properties, a polyfunctional lactone and a polyfunctional isocyanate. The product is soluble in alkaline solutions and may be used for light sensitive photographic layers on films, paper or glass; in drug delivery systems, as burn dressings, in body implants such as vascular prosthesis, and in the manufacture of catheters. The novel polymers also find use in the manufacture of artificial finger nails, finger cots, adhesives, and in protective and hydrostatic drag resistant coatings. The water absorptivity of the polyurethane lactone polymers is above 10%, preferably above 20%, and these polymers may range to completely gel-like high water absorptive polymers.

Abstract: Polyurethane polymers characterized by a molecular weight above 6,000 and having lactone groups and hydroxyl groups in the polymer backbone are prepared by reacting a mixture of polyols, a polyfunctional lactone and a polyfunctional isocyanate proportioned so as to provide the desired polymer properties. The product is soluble in alkaline solutions and may be used for light sensitive photographic layers on films, paper or glass; in drug delivery systems, as burn dressings, in body implants such as vascular prosthesis, in molding compositions, and in the manufacture of catheters. The novel polymers also find use in the manufacture of artificial finger nails, finger cots, adhesives, and in protective and hdyrostatic drag resistant coatings. The water absorptivity of the polyurethane lactone polymers is above 10%, preferably in the range of about 20% to 60%, and these polymers may range in their physical properties from rigid solids to completely gel-like high water absorptive polymers.

Abstract: A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on a liquid mixed isopropylphenyl/phenyl phosphate ester and contains small amounts of bis[4-(dimethylamino) phenyl]methane, benzotriazole and a mixed mono- and dialkylphosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms.

Abstract: A high sodium oxide composition suitable for use in the manufacture of glass and fiber glass is prepared by heating a sodium carbonate ore with a silicate or other source of glass making oxides such as clay or oil shale. The product obtained is rich in sodium, calcium and magnesium oxides and contains less than 35 weight percent SiO.sub.2. It may be substituted for soda ash in a glass batch and will reduce the fuel required in glass manufacturing.

Abstract: An electrode that is specific for the isocyanurate ion, and capable of rapid determination of the free isocyanurate ion activity directly in solution uses as its sensing element a platinum wire covered with a polyvinyl chloride membrane. The membrane is plasticized with a solution of a quaternary ammonium salt of isocyanuric acid. When this electrode and a commercial reference electrode are immersed in a solution containing the isocyanurate ion, a differential voltage proportional to the isocyanurate ion concentration is generated which is detected by a pH meter.

Abstract: A stable viscous liquid bleach that may be safely applied directly to stubborn stains is prepared by adding certain anionic or nonionic surfactants to aqueous solutions containing up to 30% by weight hydrogen peroxide. The viscosity of the aqueous hydrogen peroxide solution is adjusted to be within the range of about 60 cps - 6,000 cps by addition of a water dispersible copolymer of an alpha-beta monoolefinically unsaturated lower aliphatic carboxylic acid crosslinked with a polyether of a polyol selected from the class consisting of oligo saccharides, reduced derivatives thereof in which the carbonyl group is converted to an alcohol group and pentaerythritol, the hydroxy groups of said polyol which are modified being etherified with allyl groups, said polyol having at least two allyl groups per polyol molecule.

Abstract: Aqueous waste streams from the production of chlorinated isocyanurates are oxidized with sodium hypochlorite to remove therefrom dissolved cyanurate compounds.
