Patent number: 7976028Abstract: By improving a metal gasket having a corrugated portion which is advantageous in sealing property, a non-asbestos gasket in which the sealing property is further improved is provided. A non-asbestos gasket has a three-layer structured sealing portion S configured by: a core layer 1A which is made of a plate of a metal, and which is formed into a concentric circle-like corrugated shape; and surface layers 2, 3 which are made of expanded graphite, and which are stacked on the front and back faces of the core layer, respectively. In an outer circumferential end of the sealing portion S, the core layer 1A is protruded from the front and back surface layers 2, 3 toward an outer diameter side. In an inner circumferential end of the sealing portion S, the front and back surface layers 2, 3 are protruded from the core layer 1A toward an inner diameter side, thereby covering the core layer 1A.Type: GrantFiled: August 6, 2007Date of Patent: July 12, 2011Assignee: Nippon Pillar Packing Co., Ltd.Inventors: Takeshi Miyoshi, Hiroki Hayashi, Masao Konaka, Yoshinari Kobuchi, Hiroyuki Sasakura

Publication number: 20110156352Abstract: A gasket for sealing two mating surfaces is described. The gasket has: a) an outer portion comprising a core interposed between sealing layers, the outer portion defining a first aperture, the core and/or the sealing layers defining an inner edge of the outer portion, the said inner edge immediately surrounding the first aperture; b) an inner portion comprising deformable material defining a second aperture therein, the inner portion having an inner edge defining the second aperture and an outer region designed to be secured to the outer portion so that the inner portion is held securely by the outer portion, the thickness of the inner portion being greater than the thickness of the outer portion so that in use the inner portion deforms to a greater extent than the outer portion. In some embodiments, the deformable inner portion includes a chemical treatment agent. The invention extends to methods of using the gaskets, uses for sealing corroded joints and methods of production of the gasket.Type: ApplicationFiled: December 22, 2010Publication date: June 30, 2011Inventors: Stephen Peter Bond, Anthony Russell Currie, Stephen Woolfenden, Dean John Kirby

Publication number: 20110123319Abstract: A seal assembly for a turbo machine, such as a turbo jet, includes a housing having a retainer secured relative to the housing. A seal is arranged between the housing and the retainer. The seal provides an opening configured to receive a penetrating element. The seal comprises a composite material. In one example, an anti-rotation feature prevents the seal from rotating relative to the housing. The anti-rotation feature includes a rivet received in a hole in the seal that cooperates with at least one of the housing and the retainer to maintain the seal in a desired angular position.Type: ApplicationFiled: November 25, 2009Publication date: May 26, 2011Inventors: Jonathan Jeffery Eastwood, Judith F.
