Publication number: 20040224589Abstract: A method is disclosed for using discarded carpet segments or other recycled textiles to make wood-like material in sheets that are comparable to plywood. The carpet segments or other recycled materials are shredded, then layered across a slow-moving conveyor to form a thick, low-density belt of fibers.

Patent number: 6451429Abstract: The present invention is directed to a novel process of making N-isopropyl acrylamide (NiPAm) polymers based upon the reaction of poly(acrylic acid) and N-isopropylamine. The disclosed method of the present invention uses polyacrylic acid as a starting material to synthesize NiPAm polymers. In one embodiment, the present invention discloses a condensation reaction of an intermediate salt to form homopolymers, copolymers and terpolymers of N-isopropyl acrylamide (NiPAm) with acrylic acid and/or alkyl acrylates in a molten state, which is adaptable to a continuous reactive extrusion process. Binder compositions, water-dispersible products and thermoformable articles containing the NiPAm polymers are also disclosed.Type: GrantFiled: May 18, 2001Date of Patent: September 17, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Pavneet Singh Mumick, Yihua Chang, James Hongxue Wang

Patent number: 6416854Abstract: A uniformly applied monolithic roofing surface membrane at appropriate thickness and pitch is field applied upon a surface. The surface membrane may be field applied from a spray applicator foam dispenser moving between two parallel tracks. The uniform application of foam at each pass is assured, by accelerating the speed of the foam dispenser at the end of each pass, by providing continuous movement of the spray applicator upon the tracks. The monolithic roofing surface monolithic thus formed includes a spontaneously curable polymer, such as low rise polyurethane adhesive or polyurethane foam, having a mesh such as of fabric or fiberglass therein, with a silicone coating thereon.Type: GrantFiled: February 22, 1999Date of Patent: July 9, 2002Inventor: John P. Hunter, Jr.

Publication number: 20020029860Abstract: A moisture barrier paper is comprised of a fiber mat and a unique moisture barrier coating. The moisture barrier coating coats substantially every fiber throughout the fiber mat. The moisture barrier paper is created in a wet-end, on-machine process where a liquid, moisture barrier coating is sprayed onto a forming fiber mat and is drawn through the fibers with vacuum. The moisture barrier paper has top and bottom surfaces that are substantially free of wax and polymeric water repellants. The moisture barrier paper is completely repulpable.Type: ApplicationFiled: May 7, 2001Publication date: March 14, 2002Applicant: Liberty Diversified IndustriesInventor: Rodney D. Hamar
