Publication number: 20040175559Abstract: A technique and device for rehabilitating or repairing waste water system components or the like, comprising a spray-applied, multi-layer liner which seals the components and imparts structural integrity. The liner comprises a primer layer, a first moisture barrier layer, a foam layer and a second moisture barrier layer. The first and second moisture barrier layers are preferably made of the same material and form a skin on both sides of the internal foam layer. The combination of the foam layer and the two moisture barrier layers imparts structural strength and rigidity to the cured liner.Type: ApplicationFiled: March 11, 2004Publication date: September 9, 2004Inventor: James M. Hume

Patent number: 6733888Abstract: Disclosed is a floor-covering material, in which a phenol composite resin comprising phenol resin of resorcinol-formaline and polyurethane resin is incorporated with paper and dried, to form a prepreg, which is then thermally compressed to the upper side of a PVC base or a waterproof plywood layer, yielding a transparent protective layer and a shaping layer. In the flooring material, the transparent layer and the shaping layer are made of phenol composite resin, and thus low in heat- and moisture-distortion, with no curling. Further, since a surface layer of the floor-covering material is hardly distorted by heat, a balance layer for the suppression of such distortion is not additionally required.Type: GrantFiled: October 2, 2002Date of Patent: May 11, 2004Assignee: Woojin CorporationInventors: Je-suk Woo, Chang-guen Lee, Hyeong-keor Yoo, Sung-il Kim

Patent number: 6733877Abstract: In order to create a full grain napa cowhide which exhibits the characteristics with respect to grain pipeyness and water vapor permeability that are required by the automotive and upholstery industries, a finish is applied to the grain side of the full grain leather. The finish includes a pigmented layer with a thickness of between 0.015 mm and 0.04 mm and is formed of a stabilized polyurethane and/or polyacrylate dispersion. The dispersion contains microspheres with a diameter of less than 45 &mgr;m, which form primarily closed cells, and at least 10% open cells by volume. The top side of the layer is provided with a napa embossing. A second layer, placed on the first layer, is formed from a cross-linked polyurethane-based varnish application containing a dulling agent. The leather undergoes a milling treatment.Type: GrantFiled: October 4, 2002Date of Patent: May 11, 2004Inventor: Philipp Schaefer

Patent number: 6726971Abstract: Flame retardant, clear pressure-sensitive adhesive tape comprises clear polyether-based polyurethane backing film and clear, polyether-based polyurethane pressure sensitive adhesive coated on one side of the backing film. Flame retardant is incorporated into the polyurethane backing film and the polyurethane adhesive to render the tape substantially flame retardant without causing a loss of the substantial transparency of the tape. The tape meets the following flame retardancy requirements: maximum average burn extinguishing time of 15 seconds, maximum average burn length of 8 inches and maximum average drip extinguishing time of 5 seconds, measured in accordance with defined test methods.Type: GrantFiled: December 13, 1999Date of Patent: April 27, 2004Assignee: Tyco Adhesives LPInventor: Wilkey Wong
