Abstract: A method of disposing of medical waste is disclosed wherein medical waste generated at a facility such as a hospital, clinic, and/or a doctor's office, after being bagged and sterilized, usually by a stem autoclave, is delivered to a mobile carrier having a shredder or similar device, for finely-dividing the sterilized waste which is then compacted and transferred to a storage area on the carrier where it can be commingled with sterilized shredded medical waste obtained from other facilities having been processed in like manner, before being transported to a sanitary disposal site.

Abstract: A process for the manufacture of bis-methylene spiro-orthocarbonate (BMSOC) wherein methyallyl chloride is subjected to the action of chlorine gas to form a mixture of 1,1-dichloromethyl ethylene and other chlorinated hydrocarbons which need not be and are not separated. The mixture is merely treated wich an alkali metal acetate such as sodium acetate to yield an easily separable second mixture by fractional distillation. The desired 1,1-diacetoxymethyl ethylene is thus recovered in high yield. It is then converted by transesterification in over 90% yield to the bismethylene spiroorthocarbonate (BMSOC). BMSOC is useful as a component for coatings composites, adhesive formulations and the like, which have the unique ability to (a) cure by free radical initiation and (b) expand during cure. BMSOC may be used as a component for dental composites, i.e. filling materials, because it reduces the possibility of leakage at the margin, i.e. at the composite-enamel interface and as a component in bone cements.

Abstract: Certain substituted thioglycolates and thiopropionates were found useful as secondary stabilizers for polymers, particularly polyvinyl chloride, when used in conjunction with metal octanoates, such as zinc octanoate, as the primary stabilizer. The specific thioglycolates and thiopropionates are those formed by thio adducts to the double bond of a monomer, such as the product of reacting isooctyl thioglycolate with glycidyl acrylate, to provide isooctyl S-2(glycidyloxycarbonyl)ethyl thioglycolate, as an example.

Abstract: The machine processing character as well as the stress-strain properties of polyester polyurethane foam are improved by the use of a cross-linking polyol, a viscosity increasing dicarboxylic acid or anhydride such as phthalic anhydride, and by the use of specific minor amounts of poly(oxyethylene) glycol, in the esterification formula of foam grade polyester resins. A nonhydrophillic flexible polyester based polyurethane foam is produced.

A C.sub.10-24 aliphatic hydrocarbon polybrominated and polychlorinated to contain about 10 to 50 weight percent of bromine and about 5 to 60 weight percent of chlorine; the weight ratio of A to B ranging from about 5:1 to 1:5, optionally combined with a flame-retardant synergist such as antimony oxide.

Abstract: Synthetic detergent bars containing alkyl sulfosuccinate, surfactant, waxy extender and water, and process for preparing same.

Abstract: A stable aqueous dispersion latex of a room temperature curing polyurethane forming films resistant to water and organic solvents is disclosed, the polyurethane containing units derived from melamine, in addition to units derived from diisocyanate and difunctional reactants, in the polymer chain, pendant water-dispersing carboxylic salt groups, and room temperature curable and cross-linking N-methylol hydrazide termini, and methods for making such dispersion.

Abstract: Sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an ethoxylated or propoxylated non-tertiary monoamine, for instance, a C.sub.8 -C.sub.18 fatty amine, ethoxylated with 3 or 4 moles of ethylene oxide, to form a hydroxyl-containing tertiary amine, and in which the other carboxyl group of the sulfosuccinate is esterified with an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-monoepoxides, and method of preparation of such sulfosuccinate diesters. The said sulfosuccinate diesters have utility as surfactants, such as detergents and emulsifiers.

C. range.

Abstract: A process for making a mixed product of dimethyltin dichloride and methyltin trichloride by reacting dimethyltin dichloride with stannic chloride without catalyst. The mixed product is useful as an intermediate, without further purification, in the preparation of corresponding mercaptide stabilizer for vinyl chloride polymers.

Abstract: A urethane foam gun is disclosed in which polyisocyanate and polyol feed streams are mixed with air under pressure within the gun with vigorous intermixing in the outlet nozzle to a condition ready for application. Once applied the foam polymerizes in place. The gun is formed with an integral block design in which dual plug valves are mounted for control of the streams. Actuation is achieved by a trigger valve mounted on the gun, and a second gun-mounted valve controls a solvent flush for cleaning to avoid polymerization within the gun itself. The gun is useful for foam-in-place applications, such as protective packaging.

Abstract: Clarified slurry oil feedstock is heated at temperatures above 340.degree. C. and preferably between 390.degree. C. and 410.degree. C. for periods exceeding a minimum of about 2 hours, under reflux conditions and in the absence of air, so as to maximize the polymerization of light ends in the formation of petroleum pitch. An increased yield of petroleum pitch is obtained from the clarified slurry oil feedstock.

Abstract: A waste stream of nonvolatiles is recovered (NVR) as a by-product from the oxidation of cyclohexane to cyclohexanone and cyclohexanol in the process for making adipic acid.

A particularly useful end-product is a rigid polyurethane foam having good cell structure and a density of at least 2.0 lb./cu. ft.
