Patent number: 5704104Abstract: A method and machine are disclosed for using a cold dry abrasion step for separating segments of discarded carpet into pile material (usually nylon) and backing layers (usually polypropylene) for recycling. A preferred method of abrasion uses dry ice pellets (made of frozen carbon dioxide) which are ejected at high speed from a set of nozzles that shoot the pellets directly into an abrasion zone, as a segment of discarded carpet on a conveyor system is being stripped apart and disassembled. The dry ice pellets "freeze" the binder material (usually latex) by lowering it to a temperature that makes the binder brittle and easy to break apart. The pellets also serve as abrasive agents, in a manner comparable to sand-blasting; however, unlike sandblasting or liquid (steam or chemical) systems, the dry ice pellets evaporate (sublimate) directly into gas without going through a liquid phase, and without leaving any liquid or gritty residue.Type: GrantFiled: December 27, 1995Date of Patent: January 6, 1998Inventors: Forrest C. Bacon, Wendell R. Holland, Lial H. Holland

Patent number: 5589254Abstract: A method for increasing the energy absorption of a fabric constructed of high tenacity fiber. This method modifies the ballistic stress-deflection curve of the fabric by effectively toughening the fabric by controlling the peak stresses generated in the fabric layer. These stresses are controlled by perforating the fabric into relatively narrow portions or cutting the fabric into relatively narrow strips, preferably along the bias. This unexpected property is counter-intuitive to known expertise in this area in that the weakening of the fabric by cutting or perforating actually improves the ballistic performance.Type: GrantFiled: May 15, 1995Date of Patent: December 31, 1996Assignee: Milliken Research CorporationInventor: Louis Dischler

Patent number: 4948549Abstract: A process is described for producing filter elements which contain a cross-wound yarn as the filter material, wherein twisted yarn of fine individual fibers is roughened to enhance its filtering action. The yarn may be heat-resistant and the filter element may be used as a soot filter in the exhaust gas stream of an internal combustion engine. Before the yarn is wound up, fiber tufts are broken up by pulling the yarn under tension over a moving roughening surface, the direction of movement of the roughening surface differing by an angle alpha from the direction of movement of the yarn in the area of contact between the yarn and the roughening surface, and the angle alpha being selected in relation to the twist of the yarn, particularly so that the threads of the yarn in contact with the roughening surface are oriented transversely to the direction of movement of the roughening surface. The process produces a roughened yarn which provides the required high filter performance for a soot filter.Type: GrantFiled: August 23, 1988Date of Patent: August 14, 1990Assignee: Filterwerk Mann & Hummel GmbHInventors: Hans Erdmannsdorfer, Helmuth Fischer, Helmut Rocker, Hartmut Wolff, Fritz Zundel
