    摘要： An assembly for cleaning a conveyor belt system is disclosed. The cleaning assembly is for a conveyor belt system with the type having first and second endless belts which each traverse a separate belt travel path and together define a generally upright article transport path between opposed top faces of the belts. The cleaning assembly includes a belt wiping blade assembly for moving liquids and debris from a belt, an absorbent material downstream from the blade assembly for wiping excess liquid from the belt, and belt edge seals disposed between the opposed top faces of the belts along the article transport path.

    摘要： A method for microencapsulating quaternary ammonium salts by interfacial polymerization. The polar component comprises a quaternary ammonium salt, glycerine, triethyleneglycol diamine, a C 4-10 straight or branched aliphatic compound having two primary amine functionalities, and a C 4-10 straight or branched aliphatic compound having at least three primary amine functionalities. The glycerine-immiscible oil component comprises mineral oil, an aliphatic polyisocyanate and a surfactant. The mole equivalent ratios of primary amine to isocyanate in this reaction is about 0.01-3:1. Microcapsules made by this method are unique and provide surprising benefits in durability, elasticity and barrier properties in resistance to leaching of the microcapsule fill material.
