Patent number: 6210779Abstract: Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through an amorphous binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles. A lower layer of the photocatalytic layer is embedded in the binder layer such that an intermediate layer is formed between the binder layer and the photocatalytic layer, the intermediate layer including components of the binder and photocatalytic layers in varying concentrations therethrough.Type: GrantFiled: October 7, 1998Date of Patent: April 3, 2001Assignee: Toto Ltd.Inventors: Toshiya Watanabe, Eiichi Kojima, Keiichiro Norimoto, Tamon Kimura, Mitsuyoshi Machida, Makoto Hayakawa, Atsushi Kitamura, Makoto Chikuni, Yoshimitsu Saeki, Tatsuhiko Kuga, Yasushi Nakashima

Patent number: 6207244Abstract: A wall or structural element, preferably for the body or parts of the body of motor vehicles, is formed for dissipating impact forces and introducing them into the load-bearing parts of the body of the motor vehicle. The wall or structural element is a composite element formed of a thin-section wall part and a molding which is bonded to the latter over its full surface area. The molding being composed of reinforcing elements fixed in a foamed binder. The reinforcing elements are derived from renewable raw materials in cut or uncut form, preferably monocotyledons or dicotyledons. Two or more composite elements, in each case having wall parts and moldings, may be bonded to one another to form a joint component, for example a motor vehicle door.Type: GrantFiled: September 10, 1998Date of Patent: March 27, 2001Assignee: Moeller Plast GmbHInventor: Rolf Hesch

Patent number: 6196708Abstract: An article, such as a filter or film, has a treated laminate with an expanded PTFE membrane and a porous support scrim. The treated laminate is formed by contacting a laminate having an expanded PTFE membrane and a porous support scrim with an oleophobic treatment agent dissolved in an organic solvent. The oleophobic treatment agent is deposited onto the expanded PTFE membrane and porous support scrim as the organic solvent is removed. The oleophobic treatment agent is typically a fluoropolymer. The article can be used, for example, as a filter over a port in a housing of an electronics or other device.Type: GrantFiled: May 14, 1998Date of Patent: March 6, 2001Assignee: Donaldson Company, Inc.Inventor: Robert M.

Patent number: 6194064Abstract: The present invention is a pressure sensitive adhesive for use on a wallcovering to cover a surface such that the wallcovering is repositionable and removable without damage to the surface. The pressure sensitive adhesive is made by combining a plurality of water based acrylic emulsions and a plurality of hollow glass bubbles having a density and size to be present at the surface of the pressure sensitive adhesive and reduce initial tack to allow movement of the wallcovering on the wall surface. The hollow glass bubbles halve a density within the range of 0.05 to 0.10 g/cc and a size within the range 40 to 177 microns in diameter. Additives can be added to the pressure sensitive adhesive of the present invention such as surfactants, defoamers, thickeners, and tacking resins. The pressure sensitive adhesive is applied to a wallcovering and dried to evaporate the water content.Type: GrantFiled: December 3, 1997Date of Patent: February 27, 2001Assignee: Dyna-Tech Adhesive, Inc.Inventors: David R. Keely, Richard C. Oldack
