Patent number: 8398225Abstract: A foamed liquid coating apparatus prevents curling or warping of a sheet caused by coating irregularities when coated with a preprocessing solution using a coating roller or a liquid discharge head. The foamed liquid coating apparatus includes a container holding a liquid that can be foamed. A first foamed liquid producing/transporting unit produces a foamed liquid having a foam size greater than a required foam size from the liquid supplied from the container. A second foamed liquid producing/transporting unit produces a foamed liquid having the required foam size from the foamed liquid produced by the first foamed liquid producing/transporting unit. The foamed liquid produced by the second foamed liquid producing/transporting unit is applied onto a first coating roller. The foamed liquid is further supplied from the first coating roller to a second coating roller that coats a sheet with the foamed liquid.Type: GrantFiled: July 4, 2008Date of Patent: March 19, 2013Assignee: Ricoh Company, Ltd.Inventors: Minori Ichimura, Kazuyoshi Matsumoto, Manabu Izumikawa, Takeshi Takemoto, Yasuhisa Kato, Yasuo Katano

Patent number: 8398794Abstract: A method for manufacturing a polishing pad, which may be laminated, with a small number of manufacturing steps, high productivity and no peeling between a polishing layer and a cushion layer includes preparing a cell-dispersed urethane composition by a mechanical foaming method; continuously discharging the cell-dispersed urethane composition onto a face material, while feeding the face material; laminating another face material on the cell-dispersed urethane composition; curing the cell-dispersed urethane composition, while controlling its thickness to be uniform, so that a polishing layer including a polyurethane foam is formed; cutting the polishing layer parallel to the face into two pieces so that two long polishing layers each including the polishing layer and the face material are simultaneously formed; and cutting the long polishing layers to produce the polishing pad.Type: GrantFiled: November 11, 2011Date of Patent: March 19, 2013Assignee: Toyo Tire & Rubber Co., Ltd.Inventors: Takeshi Fukuda, Tsuguo Watanabe, Junji Hirose, Kenji Nakamura, Masato Doura

Patent number: 8328971Abstract: Laminated metallic sheets which comprise an interior layer of a viscoelastic polymeric compound sandwiched between outer layers of metallic sheet may exhibit enhanced properties through modification of the viscoelastic phase. In a first embodiment the elastic modulus of the viscoelastic polymeric compound may be reduced by incorporating voids, bubbles or pores within the compound. These voids which may be introduced by introduction of polymeric microspheres are effective in reducing the internal stresses induced in the laminate by temperature changes. In a second embodiment, coating the microspheres with an electrically-conductive layer may be effective in enabling resistance spot welding of such laminated materials.Type: GrantFiled: April 29, 2010Date of Patent: December 11, 2012Assignee: GM Global Technology Operations LLCInventors: Hamid G. Kia, Mark W. Verbrugge, Douglas L. Faulkner

Patent number: 8283017Abstract: The present invention pertains to carpet and method of making it. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched linear ethylene polymer. The method includes extrusion coating at least one homogeneously branched linear ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations.Type: GrantFiled: May 4, 2004Date of Patent: October 9, 2012Assignee: Columbia Insurance CompanyInventors: John O.

Publication number: 20120241079Abstract: The present invention provides a foamed member capable of inhibiting or preventing foam breakage at the time when the foam member is peeled from a carrier tape, even when the foamed member has a high expansion ratio. The foamed member has a thermoplastic resin foam layer containing a thermoplastic resin foam formed through a step of impregnating a high-pressure inert gas into a thermoplastic resin and subsequently reducing pressure, and at least one of a thermoplastic polyester-based resin layer and a thermoplastic elastomer resin layer disposed on at least one side of the thermoplastic resin foam layer.Type: ApplicationFiled: June 7, 2012Publication date: September 27, 2012Applicant: NITTO DENKO CORPORATIONInventors: Makoto SAITOU, Yasuyuki Tokunaga, Hideki Nagatsu

Publication number: 20120189838Abstract: A layered insulation panel including a rigid polyisocyanurate foam layer and, adhered to at least one surface thereof, a facing material. The two materials are adhered by a two-component polyisocyanurate adhesive, and both the polyisocyanurate adhesive and the polyisocyanurate foam layer undergo polymerization concurrently and in place. The result is that the tensile bond strength between the polyisocyanurate foam layer and the facing surface is improved, due to interaction between the polymerization occurring at the surface of the foam layer and the polymerization of the polyisocyanurate adhesive.Type: ApplicationFiled: September 15, 2010Publication date: July 26, 2012Applicant: Dow Global Technologies LLCInventors: Luigi Pellacani, Robert M.

Publication number: 20120141724Abstract: A reinforcement including at least two separate members that are secured to each other. The reinforcement may further include a bonding material that is disposed on at least one of the members and confined within an outer perimeter of the carrier. The bonding material may be configured to secure the carrier to the structure. The two members are secured to each other to permit at least one of translational and rotational relative movement therebetween such that one of the members engages the bonding material, thereby forcing the bonding material beyond the outer perimeter of the carrier.Type: ApplicationFiled: December 7, 2011Publication date: June 7, 2012Applicant: SIKA TECHNOLOGY AGInventors: Vincent BELPAIRE, François Godillon
