Abstract: A catalytic composite and its use in the fluidized catalytic cracking of hydrocarbons in the absence of added hydrogen. The composite comprises a binder material, a crystalline aluminosilicate, preferably a Y-type zeolite, and diatomaceous earth. Optional ingredients are kaolin, barium titanate and discrete particles of porous alumina. Absent from the composite is a supported catalytically active metal or metal oxide. The catalytic composite of the invention achieves higher gasoline production with lower coke production as compared to FCC catalysts with no diatomaceous earth content.

Abstract: An improved method of using polymer compositions to produce foamed plastics, wherein a major, auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates. The dialkyl dicarbonates can be decomposed over temperatures ranging from about 10.degree. C. to about 45.degree. C. when used in combination with particular tertiary amine decomposition catalysts. Enhanced production of carbon dioxide is obtained by the addition of water.

Abstract: An assault weapon for penetrating enclosed targets includes means for fastening the weapon to the surface of the target while it is penetrated by non-explosive penetration means such as a thermal lance. Once the target is penetrated, offensive agents can be introduced. In one embodiment, the fastening means and penetration means can be combined in the form of a hollow bayonet which penetrates the surface of unarmored targets on impact.

Abstract: A liquid coating composition is provided which comprises, as a binder, a compound containing at least two pendant activated unsaturated groups and, as a crosslinking agent for the activated unsaturated groups, a particular unblocked monoprimary amine compound. The liquid coating compositions of the present invention provide the particular advantage of surprisingly good potlife without blocking the crosslinking agent, with the resulting coating compositions displaying good properties such as, for example, solvent resistance.

Abstract: The present invention pertains to a crosslinkable binder resin comprising an acrylate copolymer backbone having as pendant groups water soluble half esters of dicarboxylic acid and crosslinkable olefinic groups which contain an activated ethylenic unsaturation, such as (meth)acryloyl groups. The (meth)acryloyl groups can be crosslinked by polyfunctional crosslinking agents such as amino or blocked amino crosslinkers. The water-soluble half esters preferably are formed by the reaction of pendant hydroxy groups with unsaturated cyclic anhydrides (the unsaturation providing an additional crosslinking site). The (meth)acryloyl groups preferably are formed by the reaction of pendant epoxy groups with (meth)acrylic acid or derivatives thereof.

Abstract: A binder system is provided which is suitable for use as a waterborne coating, particularly as a topcoat over hydro-basecoats. The binder in accordance with the present invention comprises a water-soluble acrylic resin which has been modified using a monoisocyanate functional compound. The waterborne coating comprises this binder system in an aqueous base. The resulting waterborne coating exhibits high gloss, high solids content with low cosolvent content, good application characteristics, and good stone-chip and weathering resistance. The present waterborne coating also finds use, for example, as an electrocoat, primer/surfacer and/or solid color topcoat.

These compositions display good stability, extended potlife, and a good balance of physical and mechanical properties making them suitable for a wide variety of coating, impregnating, sealing and bonding application.

Abstract: The present invention pertains to a dispersion in an organic liquid of an acrylate-based and/or methacylate-based addition polymer stabilized by a graft copolymer of a polybutadiene with particular monomer components grafted thereon. The present invention also pertains to coating compositions based upon such a dispersion and to a process of coating a substrate with the coating composition. Finally, the present invention relates to a process for the preparation of the stabilizer for the dispersion.
