Abstract: A toy in the shape of a collapsible and expandable box is made of cardboard and has a stiff, square top and bottom and four side walls which can be folded to the outside along central folding lines by pressure onto the top. Each side wall is provided with an inwardly extending tongue, and each two tongues on opposite side walls are connected by elastic bands or springs which pull the walls back from their folded position into planar state, as soon as the pressure on the top is released. In this position the toy forms a cube, which may be decorated with pictures, maps, symbols or the like.
Abstract: A flooding compound for a waterproof communications cable is formed from a heated mixture of 92-94% by weight of a microcrystalline wax, 3-5% polyethylene and 2-4% of a rubber. The heated mixture is extruded between the plastic jacket and core sheath of a cable. The compound exhibits the adhesive and slip characteristics of, and is a replacement for, atactic polypropylene.

Abstract: An engine or lubricating oil containing 0.03 to 0.3% by weight of a succinic anhydride promoter reaction product for a overbased magnesium sulfonate, based on the presence of 0.5% by weight of Mg metal in the oil, and wherein the weight of the reaction product is commensurately proportional to the weight of Mg metal in the oil, and which oil is a free of post sulfonate formation water-tolerance additives, nevertheless passes the rigorous Cummins water tolerance test. Copromoters such as a naphthenic acid and/or a salicylic acid may be employed.
Abstract: Method of making a stable aqueous dispersion of polymeric material comprising:(A) producing an NCO-terminated polyurethane prepolymer in the presence of inert liquid polymerizable ethylenically unsaturated monomer material,(B) dispersing the product from A in water,(C) chain-extending the prepolymer in the resulting aqueous dispersion, and(D) subjecting the aqueous dispersion from C to vinyl addition polymerization conditions to polymerize said monomer material in situ, the weight ratio of chain extended polyurethane to said monomer material being about 9:1 to about 1:9., the resulting aqueous dispersions, and their use for making films, sheets and other products.
Abstract: A process for the preparation of overbased oil soluble magnesium sulfonates comprises contacting an acidic gas at a temperature between about 50.degree. F. up to the reflux temperature of the mixture, with a mixture consisting essentially of a sulfonic acid or salt thereof, a volatile aliphatic or aromatic or chlorinated hydrocarbon solvent, a non-volatile diluent oil, a light magnesium oxide, water, methanol and combination of promoters, wherein the first promoter is one selected from an oil soluble naphthenic acid and an oil soluble carboxylic acid or salt thereof; and a second promoter being one selected from: ##STR1## wherein X is one of H, OH, NH.sub.2, CO.sub.2 H, OCOCH.sub.3 and SH, and Y is one of H, CH.sub.3 and CH.sub.2 CH.sub.3, wherein the second promoter is less oil soluble than the first promoter; and (b) a water soluble C.sub.1 -C.sub.6 carboxylic acid.
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.

Abstract: A liquid flame retardant composition consisting essentially of:A. A polybrominated diphenyloxide containing about 4 to 9 nuclearly substituted bromine atoms and;B. 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: 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.

Abstract: A simple, direct, and safe process for preparing an organic solvent solution of a lower trialkyltin hydride of high purity and in high yield by reacting a lower trialkyltin chloride with an alkali metal bis(2-alkoxyethoxy)aluminum dihydride in a hydrocarbon solvent boiling in the 50.degree. to 200.degree. C. range.
Abstract: A trialkyltin chloride in which the alkyl groups have from about one to six carbon atoms is prepared, without detectable tetraalkyltin, from the corresponding dialkyltin dichloride in one step and in high yield using a catalyst mixture comprising a trihydrocarbylamine or trihydrocarbylphosphine and stannic chloride.
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: A rigid shrink stable polyurethane foam having a K factor value below 0.22 and having substantially all closed cells is prepared from a reaction product of an arylene polyisocyanate and an addition product of an alkylene oxide having at least three carbon atoms and a polyol having at least four hydroxy groups using a chlorofluoro-lower alkane blowing agent.
