Abstract: Methods for making compositions for making thermoplastic aliphatic urethane/urea elastomers, which are in turn used to make molding compositions used in forming molded articles, particularly, shells for automotive applications. The molding compositions comprise an aliphatic thermoplastic urethane/urea elastomer and a polyolefin-based modifier. These compositions may be used to form a powder, pellets, microspheres or minibeads which may then be cast to form air bag door and instrument panel cover skins which may meet automotive deployment and weathering requirements.

Abstract: A packaged concrete additive includes ground, expanded perlite with a volume weighted mean particle size of approximately 10-100 ?m. The perlite optionally includes at least one additional component to improve workability and compensate for the natural tendency of expanded perlite to absorb water from the concrete mix. The additional component can include: water; a superplasticizer such as polycarboxylates, naphthalene sulfonate, and melamine sulfonate; or a hydrophobic compound, such as salts of fatty acids, fatty acids, silanes, and siloxanes. The additive is a flowable powder and for convenience of use it is packaged in a bag that can be directly added to the concrete batch and disappears on mixing. Concrete containing this additive displays superior properties to conventional concrete. Expanded perlite is a readily available raw material and the finished concrete is suitable where high strength structural concrete must withstand high temperatures.

Abstract: A concrete additive includes expanded perlite with a volume weighted mean particle size of approximately 10-100 ?m. The perlite further includes at least one additional component to improve workability and compensate for the natural tendency of expanded perlite to absorb water from the concrete mix. The additional component can include: water; a superplasticizer such as polycarboxylates, naphthalene sulfonate, and melamine sulfonate; or a hydrophobic compound such as salts of fatty acids, fatty acids, silanes, and siloxanes. The additive can be made in the form of a flowable powder or a flowable slurry. Concrete containing this additive displays superior properties to conventional concrete, including extremely high thermal resistance and high strength, low chloride ion permeability, and good early strength. The expanded perlite is a readily available raw material and the finished concrete is extremely cost effective for applications where a high strength structural concrete must withstand high temperatures.

Abstract: A durable concrete composition includes a cementitious material comprising cement and ground expanded perlite, coarse aggregate, fine aggregate, and sufficient water for adequate workability. The resulting concrete displays a number of superior properties to conventional concrete, including extremely high thermal resistance coupled with high strength, low chloride ion permeability, and good early strength. The ground expanded perlite is a readily available material and the finished concrete is extremely cost effective for applications where a high strength structural concrete must withstand high temperatures. The mixture can be handled and placed by conventional methods and is compatible with existing conventional concrete additives.

Abstract: A troughing side idler for use with a belt conveyor having upstanding first and second side walls. A first troughing side idler is secured to the first side wall and a second troughing side idler is secured to the second side wall. A horizontally extending medial roller extends between the first and second side walls for cooperation with the side idlers to shape the conveyor belt into a trough. Each of the side idlers includes an idler roller having a shaft which extends upwardly and outwardly through inner and outer bearings which are secured to a bearing bracket housing which is operatively secured to the associated side wall. The upper outer end of the shaft has an annular groove formed therein. A set screw extends through the inner ring of the outer bearing and extends into the annular groove in the shaft. A set screw extends through the inner ring of the inner bearing for frictional engagement with the shaft. A fender washer is secured to the outer end of the shaft.

Abstract: A cooling bushing flange having a reduced amount of precious metal is provided for a glass fiber production apparatus. The flange includes a first portion formed of a precious metal or a precious metal alloy extending outwardly from a bushing and a second portion formed of a non-precious metal. The non-precious metal portion of the flange may be affixed to the precious metal portion by known metal bonding methods. A cooling tube is positioned on the non-precious metal portion to create a thermal seal and prevent molten glass from leaking from the interface of the bushing block and bushing. The precious metal portion of the inventive flange is a fraction of the size of precious metal present in conventional bushing flanges. By reducing the amount of precious metal incorporated in the flange, a significant reduction in the overall cost of the bushing and in the manufacture of glass fibers can be obtained.

Abstract: Oxime blocked polyisocyanate cross-linking agents for use with amine epoxy resin adducts in cathodic electrodeposition processes. The oxime blocking agents are the reaction products of acyclic aliphatic carbonyl-containing compounds having at least 7 carbon atoms and hydroxylamine. The oxime blocked polyisocyanates produce cathodic electrodeposited coatings which are smoother than coatings produced by oxime blocked polyisocyanates known in the art.

Abstract: Cathodic electrodepositable resin compositions particularly adapted for use as film forming compositions in cathodic electrodeposition processes. The resin is the reaction product of a modified epoxy formed by reacting a polyepoxide with a water soluble or water miscible polyol, an excess of polyamine, and a fatty acid. The resin, when combined with a cross-linking agent and solubilized in an aqueous electrodeposition bath, is capable of depositing high build coatings in a short period of time with a low cross-linking temperature in a cathodic electrodeposition process. The resin compositions are salted with an acid and used as components of aqueous cathodic electrodeposition baths.

The resin is the reaction product of a modified epoxy formed by reacting a polyepoxide with a water soluble or water miscible polyol, an excess of polyamine, and an aliphatic monoepoxide. The resin, when combined with a cross-linking agent and solubilized in an aqueous electrodeposition bath, is capable of depositing high build coatings in a short period of time with a low cross-linking temperature in a cathodic electrodeposition process. The resin compositions are salted with an acid and used as components of aqueous cathodic electrodeposition baths.
