Patent number: 6869662Abstract: The present invention relates to a non-blocking roll of roofing membrane employing a combination of silicone rubber sealant, non-woven fiberglass scrim and pressure sensitive adhesive. The method utilizes a process by which silicone rubber sealant is applied to the top surface of the non-woven fiberglass scrim and made to penetrate {fraction (1/10)} to {fraction (9/10)} of the way into the thickness of the scrim, thus no silicone rubber sealant reaches the bottom or underside surface of the scrim. To the remaining {fraction (9/10)} to {fraction (1/10)} of the scrim's thickness and to the bottom surface of the scrim is applied pressure sensitive adhesive. This construction results into a self-adherent roofing membrane that can be packaged and transferred in roll form without the need to include an additional release liner sheet or non-blocking material such as talc, mica, or clay powder.Type: GrantFiled: February 14, 2002Date of Patent: March 22, 2005Inventor: James John Barton

The top layer (1) is produced from a powder (1.1) of first particles (1.2) that are light in color and made of electrically insulating rubber, as well as second particles (1.3) embedded in it, which are made of electrically conductive, at least partially vulcanized rubber. The second particles (1.3) have a diameter D, determined by screen analysis, that is at least as great as the thickness D1 of the top layer and, for practical purposes, not greater than the total of the thicknesses of the top layer and the bottom layer D2. The first (1.2) and the second (1.3) particles are pressed together and to the bottom layer (2), without pores, and bonded by vulcanization.Type: GrantFiled: March 12, 2002Date of Patent: November 9, 2004Assignee: Carl Freudenberg KGInventors: Gerhard Graab, Klaus Heckel

Patent number: 6805925Abstract: A transmittable light-scattering sheet (a transmitting type light-scattering sheet) of the present invention comprises a plurality of layers, each having a bicontinuous structure composed of a plurality of polymers. The layers differ from each other in average period size of the bicontinuous structure. The sheet may comprise, for example, a first layer having a bicontinuous structure (e.g., the average period size of the bicontinuous structure of 1.5 to 4 &mgr;m) and a second layer each having a bicontinuous structure (e.g., the larger average period size of the bicontinuous structure than that of the first layer by 0.5 to 8 &mgr;m). In the sheet, the first layer may be next to the second layer. The ratio of the period size of the first layer to that of the second layer may be the first layer/the second layer=1.3/1 to 4/1. Such a sheet can impart a directionality to a reflected light.Type: GrantFiled: July 24, 2001Date of Patent: October 19, 2004Assignees: Daicel Chemical Industries, Ltd.Inventors: Tatsuo Uchida, Hiroyuki Takemoto

Patent number: 6803110Abstract: A decorative laminate assembly having a decorative laminate top layer assembly. This top layer assembly includes, in descending superimposed relationship, a decorative layer and a core layer that includes PETG. Preferably, the top layer assembly also includes a wear resistant overlay layer on top of the decorative layer, and the core layer's PETG is in a sheet form. The top layer assembly is attached to a water resistant substrate through the use of a water resistant adhesive. The decorative laminate assembly of the present invention can be used for a variety of purposes, including flooring applications. When the present invention is used for flooring applications, it is preferred that the overlay layer include wear resistant qualities and that the water resistant substrate comprise PVC or cement fiberboard.Type: GrantFiled: January 22, 2001Date of Patent: October 12, 2004Assignee: Formica CorporationInventors: Terry Paul Drees, Kenneth John Laurence, Kevin Francis O'Brien

Patent number: 6800384Abstract: A synthetic resin leather comprising a substrate at least one surface of which is arranged with a synthetic resin layer, wherein said synthetic resin layer contains 1 to 70 weight parts of bridged polyalkylene oxide to 100 weight parts of synthetic resin. As the synthetic resin, polyvinyl chloride resin, acrylic soft resin, mixed resin composed of 50-95 wt. % of thermoplastic polyurethane and 50-5 wt. % of acrylic soft resin, copolymer of polyester resin or polyolefin resin can be used. A surface coating layer containing powder of natural organic substance can be arranged over the surface of synthetic resin layer of said synthetic resin leather. As the powder of natural organic substance, collagen can be desirably used. Further, on the surface of the synthetic resin leather, it is desirable to mark a pattern and to make the height of convex part of the pattern higher than 0.05 mm.Type: GrantFiled: April 8, 2002Date of Patent: October 5, 2004Assignee: Okamoto Industries, Inc.Inventors: Masao Suzuki, Masao Sasaki

Patent number: 6800339Abstract: A synthetic turf comprises a backing with a plurality of pile filaments secured to the backing and extending upwardly therefrom and filled with particulate fill material. The fill material comprises a lower ballast layer of gravel residing on the backing and an upper layer of resilient particles above the lower layer. The lower layer of gravel provides weight and stability to hold down the synthetic turf without migrating to the surface. The upper layer provides cushioning and uniform resilience for the synthetic turf while the pile filaments create a grass-like appearance for the playing surface.Type: GrantFiled: August 5, 2003Date of Patent: October 5, 2004Assignee: Coevin Licensing, LLCInventors: Joseph E. Motz, Mark A. Heinlein, Stephen L. Linville

Patent number: 6790512Abstract: In one embodiment the present invention provides a coated substrate comprising a substrate, a radiation-cured coating or a thermally-cured on at least a portion of the substrate, wherein the coating comprises an inherent macroscopic texture. In another embodiment, the present invention provides a pre-cured coating mixture comprising a radiation-curable resin and an initiator, or a thermally-curable resin and thermal initiator, wherein the radiation- or thermally-curable resin and the respective initiator form a pre-cured coating mixture capable of forming a macroscopic texture upon application of the mixture on a substrate. In another embodiment the present invention provides a pre-cured coating mixture comprising a radiation- or thermally-curable resin, an initiator, and texture-producing particles having an effective size to provide a macroscopic texture upon application of the mixture on a substrate.Type: GrantFiled: September 26, 2002Date of Patent: September 14, 2004Assignee: Congoleum CorporationInventors: Richard C.
