Publication number: 20030148134Abstract: A dope is prepared by quickly and completely dissolving a polymer in a solvent. The solvent is supplied from a solvent tank to a solution tank. A measuring apparatus measures 15 to 20% by weight of a polymer with respect to the solvent and feeds the polymer to the solution tank. 5 to 15% by weight of a plasticizer with respect to the polymer is fed from a plasticizer tank to the solution tank. Stirring is carried out at 80 rpm for 30 minutes using a stirring blade in the solution tank so as to obtain a roughly dissolved solution. The roughly dissolved solution is heated at 85° C. for 10 minutes with a heater, so that all components necessary for a dope are dissolved, and only impurities are filtrated with a filtration filter. This filtrate is supplied to a dope tank, and it is used as a dope which is used in production of a film by solution film processing. A film produced from the dope has a retardation of 40 nm, and the film has little optical anisotropy and excellent optical performances.Type: ApplicationFiled: January 31, 2003Publication date: August 7, 2003Inventors: Seiichi Ono, Tsuneo Kawase

Patent number: 6596416Abstract: A decorative laminate is provided which includes one or more cellulosic core sheets, one or more decor sheets and optional overlay sheets. In one embodiment, one or more of the overlay sheets and/or decor sheets are impregnated prior to lamination with a mixture of a transparent resin and a photoluminescent material. As a result, the entire upper surface of the laminate visibly luminesces in the presence of exciting radiation. In another embodiment, an image or pattern is printed on one or more of the decor sheets with a ink including an organic photoluminescent material to provide an visibly luminescent image or pattern therein. It is envisioned that the invention could be used to provide a unique and appealing appearance when used as the surfacing for a wide variety of applications, including bowling lanes, game tables, counter-tops, dance floors, and signs such as “exit” signs.Type: GrantFiled: March 4, 2002Date of Patent: July 22, 2003Assignee: Pioneer Plastics CorporationInventors: Daniel C. Nelson, Robert A. Dumond

Patent number: 6573203Abstract: The present invention may provide a towel desirably including first and second layers having cellulosic fibers and a repellant agent. The first and second layers may substantially sandwich a third layer having cellulosic fibers with higher absorbency than the first and second layers. All three layers may form a single ply.Type: GrantFiled: July 15, 1998Date of Patent: June 3, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Wesley James McConnell, Jay Chiehlung Hsu, Joseph Mitchell

Patent number: 6544649Abstract: A hog fuel board is made by placing a hog fuel mat including an ammonium chloride catalyst with flexible non-sticking layers on outside surfaces between screens in a preheated platen press and pressing the mat to preset stops and for a predetermined time and pressure to cause adhesives naturally present in the hog fuel to disperse throughout the board. The presence of ammonium chloride as a catalyst uniformly distributed through the hog fuel mat significantly lowers the temperature required at the heating press platens to form a board which also has improved properties. There is also described a hog fuel veneer board with a hog fuel mat sandwiched between veneer sheets and a lumber product with a hog fuel coating thereon. These additional products are both formed using the ammonium chloride catalyst to reduce press temperatures and create a product with improved properties, particularly, internal bond strength.Type: GrantFiled: June 13, 2001Date of Patent: April 8, 2003Assignee: Forintek Canada CorporationInventor: Gary Ellis Troughton

Publication number: 20020164495Abstract: An ablatable, direct write imaging medium includes a polymeric matrix having a carbon pigment and an ultraviolet absorbing dye therein. The carbon pigment functions to absorb relatively long wavelengths of light to cause ablation of the medium. The ultraviolet absorbing dye gives the ablation-imaged medium high optical density in ultraviolet portions of the spectrum.Type: ApplicationFiled: April 11, 2002Publication date: November 7, 2002Inventors: Norman Sweet, Scott Zavada
