Abstract: A railway car truck includes two pairs of brake support guide assemblies connected to the side frames between the front and rear sets of wheels of the car. The support assemblies support and guide the nub ends of two brake units. The support assemblies include main support members adapted to be permanently mounted to the side frames. Additional plates with guide elements are readily attachable to the main support members to make the truck adaptable to receive different size wheel sets.

Abstract: Radiation curable compounds are disclosed comprising an amide moiety, a urethane moiety and an ethylenically unsaturated functional group, typically an acrylate functional group. This class of amide urethane acrylate compounds is characterized in having an amide moiety formed by the condensation reaction between a compound containing one or more carboxylic acid groups and an isocyanato-containing compound. Coating compositions containing one or more of these amide urethane acrylate compounds radiation polymerize at relatively high rates to provide protective and decorative films having improved wear resistance and flexibility.

Abstract: Radiation curable compounds are disclosed which are derived from the reaction of siloxy-containing carbinol, a polyisocyanate and a polyfunctional compound having hydroxy and acrylic functional groups. The compounds have high cure rates, are compatible with other components of radiation curable, film forming compositions and impart good slip and other properties to cured film coatings.
