Abstract: A composite article including a hollow form filled with a mixture of thermoplastic, a thermoset including ground whole tire waste and a processing aid. Also disclosed is a process for extruding a mixture of thermoplastic, thermoset including ground whole tire waste and a processing aid, in which the mixture is extruded through a die into a hollow form to form a filled article.

Abstract: A process for extruding a mixture of thermoplastic and ground whole tire waste, in which the mixture is extruded through a die to form an extrudate, with the extrudate subsequently cooled by directing a cooling gas toward the extrudate top, bottom and sides from a multiplicity of gas jets positioned around the periphery of the extrudate. In addition to an extruder, the apparatus includes a multiplicity of gas jets adjacent the extruder, positioned to direct a cooling gas toward the extrudate top, bottom and sides.

Abstract: Disclosed as one embodiment is a method of producing useful articles from ground whole tire waste, which includes the steps of continuously extruding a heated mixture of ground whole tire waste and thermoplastic binder material into a continuously cooled, open-ended casting chamber. The apparatus for practicing this embodiment includes an extruder, a transition nozzle having an outlet with a cross-section corresponding to the desired cross-section of the useful article, and a casting chamber being constructed and arranged to remove thermal energy from an inner surface of the casting chamber.

Abstract: A multi-purpose grooming and shedding tool suitable for removing dirt and shedding hair and simultaneously grooming animals, such as horses, is made in the form of an oval-shaped, molded plastic body member having depending grooming teeth formed in a portion of the outer periphery of the tool. A second row of grooming teeth extend downwardly from the body portion and are spaced inwardly from the outer periphery. A separate shedding blade is attached to another portion of the outer periphery of the tool and has more closely spaced teeth in it than the grooming teeth molded into the main body portion of the tool.
