Patent number: 6787214Abstract: Fire-retardant sheet element can be composed of several fire protection glass plates (2, 3). Lateral edges (9, 10) of adjacent glass plates (2, 3) therein abut one another. Into the interspace (26) between lateral edges (9, 10) a sealing configuration (7) is installed. This comprises an addition element (22) and elastic sealing elements (23, 24). The glass plates (2, 3) comprise several glass panes (16) and interspaced fire protection layers (18). These fire protection layers (18) do not extend up to the edges (9, 10) and are sealed in the regions of the lateral edges with a barrier material (20). No additional frame elements for covering the interspace (26) and for sealing are necessary.Type: GrantFiled: December 18, 2001Date of Patent: September 7, 2004Assignee: Vetrotech Saint-Gobain (International) AGInventors: Horst Seidel, Jan Strejcek, Simon Frommelt, Klaus Wildenhain

Patent number: 6770375Abstract: The fire-resistant glazing includes one or more glass pane, at least one of which consists of glass containing nucleating agents so that the glass pane is at least partially ceramicized when subjected to high thermal stress sufficient to cause ceramicizing, for example during a fire. The glass may be tempered and contains, in percent by weight based on oxide content SiO2, 55 to 69; Al2O3, 19 to 25 and Li2O, 3.2 to 5.0. This glass pane combines the advantages of the strength of tempered glass at low temperature with the stability and long-term resistance to thermal stress of glass-ceramic material at high temperature. The fire-resistant glazing can also include at least one other glass pane made of a conventional glass and at least one plastic layer of PVB film.Type: GrantFiled: January 13, 2003Date of Patent: August 3, 2004Assignee: Schott GlasInventors: Thomas Karschti, Roland Leroux

Patent number: 6764971Abstract: The present invention is directed to a durable and imaged flame-retardant nonwoven fabric that can be used for flame-retardant apparel and other related applications. The fabric is formed by providing a precursor web consisting of a blend of melamine fibers and aramid fibers. The precursor web is hydroentangled on a three-dimensional image transfer device for formation of the fabric. The resultant fabric provides desirable air permeability and Thermal Protective Properties.Type: GrantFiled: March 2, 2001Date of Patent: July 20, 2004Assignee: Polymer Group, Inc.Inventors: Karl Dewayne Kelly, Thomas A. Hill, Francois Lapierre, Spiro De Luca, Sergio Diaz de Leon

Patent number: 6764759Abstract: A thermal interface material (A) transfers heat from a heat source (12), such as a microprocessor, to a heat sink (14) for maintaining the microprocessor at a safe operating temperature. The interface material includes thermally conductive filler particles dispersed in a phase change material. The phase change material softens and flows at the operating temperature of the heat source, thereby providing good thermal contact with uneven surfaces of the heat source and heat sink, without excessive exudation and loss of the interface material. The phase change material includes a polymer component, such as an elastomer, and a melting point component, which adjusts the softening temperature of the phase change material to the operating temperature of the heat source.Type: GrantFiled: April 16, 2002Date of Patent: July 20, 2004Assignee: Saint-Gobain Performance Plastics CorporationInventors: James H. Duvall, Steve Bergerson, Charles Balian, Arthur H. Rogove

Publication number: 20040128770Abstract: A fabric having a unique combination of stain resistance, fluid barrier properties, aesthetic characteristics and drape ability is described, and a method of making such fabrics. The fabric includes a fabric substrate that has been treated with a low surface energy stain resist compound on at least one of its surfaces, and one or more layers secured to the other of its surfaces, with the layers providing the fabric with the unique combination of characteristics. In addition, the fabric is desirably provided with flame resisting and ultraviolet resisting characteristics, to enable it to be used as a seating material for transportation vehicles. Methods for making the fabric are also described.Type: ApplicationFiled: January 7, 2003Publication date: July 8, 2004Inventors: Todd Copeland, Roy P. DeMott, Thomas E.
