Abstract: Bucking bar devices, and methods of assembling bucking bars devices, for use in riveting parts together are described. In one example embodiment, the bucking bar device includes a bucking bar and a sleeve positioned so that the bucking bar extends within the sleeve. One end of the sleeve is configured to be positioned adjacent to at least one of the parts.

Abstract: A low dosage radiation polymerizable protective and decorative coating composition or paint, coated articles bearing such a protective coating and processess for preparing such articles. The radiation polymerizable coating composition comprises an organic resin/monomer mixture of:(A) between about 97 and about 3 weight percent alpha-beta olefinically unsaturated organic resin containing between about 0.5 and about 5 vinyl unsaturation units per 1000 molecular weight of said resin, and(B) between about 3 and about 97 weight percent vinyl monomers polymerizable with said resin upon exposure to radiation, characterized in that said vinyl monomers include N-vinyl-2-pyrrolidone in an amount of from about 3 and up to about 10 weight percent based on the total weight of (A) and (B).The flexible coating exhibits excellent physical qualtities and good adhesion to a variety of substrates being particularly suitable for use on vinyl chloride fabric, wherein it is discoloration resistant after heat aging.

Abstract: Free-radical curable amino vinyl ester resin binder compositions for fiber reinforced composite materials with improved interlaminar shear strength and accelerated cure rate. The composition comprises about 80 to about 20 weight percent of amino vinyl prepolymer and about 20 to about 80 weight percent of a crosslinkable diluent, wherein the prepolymer consists essentially of the reaction product of epoxy-amino alcohol adduct and unsaturated monomer having a terminal vinyl group and a hydroxy reactive functionality capable of reacting with the hydroxyl groups of the adduct. The polyepoxide and amino alcohol, preferably a diethanol amine, are reacted in a ratio of about 1:1-1.2 equivalents of epoxide to amine groups, so as to react essentially all of the epoxide groups. Subsequently, between about 0.3-1.0 of the hydroxyl groups of the adduct are reacted with the vinyl monomer.

Abstract: A low dosage electron beam radiation polymerizable protective and decorative coating composition or paint with improved weatherability, coated articles bearing such a protective coating and processes for preparing such articles. The radiation polymerizable coating composition comprises an organic resin/monomer mixture of:(A) between about 97 and about 3 weight percent alpha-beta olefinically unsaturated organic resin containing between about 0.5 and about 5 vinyl unsaturation units per 1000 molecular weight of said resin; and(B) between about 3 and about 97 weight percent vinyl monomers polymerizable with said resin upon exposure to radiation, characterized in that said vinyl monomers include N-vinyl-2-pyrrolidone in an amount of between about 3 and about 20 weight percent based on the total weight of (A) and (B); and(C) about 0.5 to about 5.
