摘要： Recompoundable polyvinyl chloride suitable to be recompounded for reuse, for example, in cable and wire production is recovered from a scrap material which includes plasticized polyvinyl chloride. A charge of plasticized polyvinyl chloride scrap material is treated with a solvent such as methyl ethyl ketone, tetrahydrofuran, cyclohexanone or dimethyl formamide to form a solvent mixture with one component thereof being a solvent solution of dissolved vinyl chloride polymer and plasticizers. The mixture is heated and agitated and scrap metal and other gross solids, if present, are removed. Then the solvent mixture is treated with an acid which advantageously causes a flocculation of suspended insolubles such as pigments and fillers. Except when using cyclohexanone as the solvent, the treatment with the acid must be accomplished, unexpectedly, in the presence of an additional flocculating agent such as a cellulose acetate which is soluble in the solution and which is insolubilized by the acid on refluxing. Recompoundable polyvinyl chloride is precipitated out by a non-solvent for the polyvinyl chloride which is miscible with the solvent in substantially all proportions, which will dissolve the plasticizer. The solvent and the non-solvent are removed from the plasticizer and are recovered separately by fractional distillation, for example.

摘要： Disclosed is a multi-cell battery pack system that includes a plurality of cylindrical cells; a cradle with an interior surface that defines a channel extending through the length of the cradle and an exterior surface that mechanically positions each of the cells radially around and parallel to the channel and exchanges heat with the cells by extending around of the circumference of the cylindrical cell and substantially extending between the two opposing end surfaces of the cell; a heat conductor that resides at least partially within the channel and exchanges heat with the interior surface of the cradle; and a heat exchanger that exchanges heat with the heat conductor, wherein the cradle, the heat conductor, and the heat exchanger cooperate to exchange heat between the cells and the heat exchanger.
