Publication number: 20050023264Abstract: A laminate, e.g. a heatable windshield has a pair of glass sheets laminated together about a member responsive to electrical stimuli, e.g. changes transmission or is heated as current passes through the member. A pair of spaced bus bars is in surface contact with the conductive member, and a lead assembly associated with each of the bus bars has a lead in contact with its respective bus bar and extends beyond the periphery of the sheets. The lead assembly further includes first and second air barriers to prevent air from moving between the sheets after the edge sealing procedure and during autoclaving of the laminate subassembly. The first air barrier is an adhesive between surfaces of the lead and inner surfaces of an electric and mechanical protective sleeve positioned over portions of its respective lead.Type: ApplicationFiled: September 1, 2004Publication date: February 3, 2005Inventors: Bruce Bartrug, Allen Hawk, Robert Pinchok, James Schwartz

Patent number: 6025025Abstract: The present invention relates to a method of improving the durability of water-repellent films deposited on the surface of a substrate and to a coated article having a water-repellent film of improved durability deposited on the substrate surface. The method includes the steps of simultaneously abrasively and chemically preparing the surface to expose an increased number of bonding sites on the substrate surface by applying a dispersion including an acid solution and an abrasive material to the surface. The dispersion is then removed and the water-repellent film is formed over the prepared surface. The bonding sites react with the water-repellent film to more effectively bond the film to the substrate and thereby improve the durability of the water-repellent film.Type: GrantFiled: June 10, 1998Date of Patent: February 15, 2000Assignee: PPG Industries Ohio, Inc.Inventors: Bruce A. Bartrug, George B. Goodwin, Chia-Cheng Lin

Patent number: 5698053Abstract: A plastic ply having at least one thermoplastic layer is positioned on a major surface of a glass ply to form a preliminary assembly, with the thermoplastic layer contacting selected portions of the major surface of the glass ply. A rigid press plate is placed on the plastic ply with the plate contacting a substantial portion of the plastic ply. Air is then removed from between the plastic and glass plies. After de-airing, the press plate is removed from the preliminary assembly and the preliminary assembly is subjected to elevated temperatures and pressures sufficient to intimately secure the plastic ply to the glass ply and form a laminate. If desired, the preliminary assembly and press plate may be heated to a temperature sufficient to soften the thermoplastic layer of the plastic ply while removing air from between the plastic and glass plies.Type: GrantFiled: June 16, 1995Date of Patent: December 16, 1997Assignee: PPG Industries, Inc.Inventors: Wendy R. Carroll, Bruce A. Bartrug

Patent number: 5543601Abstract: A multiple terminal assembly includes a plurality of connectors secured within a housing in close proximity to and electrically insulated from each other. The terminals include an electroconductive strip extending outwardly from one side of the housing and an electroconductive tab extending outwardly from an opposite side of the housing. The terminals are spaced apart a fixed, predetermined distance along the housing so that when the assembly is used to supply electrical power to a structure having current carrying members extending to a connection area along an edge portion of the structure, each of the terminal strips is aligned with one of the current carrying members at the connection area and each of the tabs is aligned with a corresponding connector of a multiple connector harness assembly.Type: GrantFiled: May 3, 1993Date of Patent: August 6, 1996Assignee: PPG Industries Inc.Inventors: Bruce A. Bartrug, Harry S. Koontz, John A. Winter

Patent number: 5089687Abstract: A dual lead electrically heatable windshield is provided with an internal jumper arrangement that allows the bus bar having the dual lead to be powered by a single external connection to one of the dual leads. A jumper arrangement may also be used in combination with a crack detector for the dual lead heatable windshield.Type: GrantFiled: October 2, 1990Date of Patent: February 18, 1992Assignee: PPG Industries, Inc.Inventors: Bruce A. Bartrug, Harry S. Koontz, John A. Winter

Patent number: 4557776Abstract: A method of preliminarily pressing a bent assembly comprising a pair of bent glass sheets and a flexible interlayer comprising a first heating step performed without vacuum, a biasing step, an unbiasing step and followed by a second heating step performed simultaneously with an application of vacuum. When the assembly so prepressed is further laminated under heat and pressure, it develops fewer bubbles after a heat stability test involving exposure to high temperature for an extended period than assemblies further laminated under such heat and pressure conditions after a prepressing step that includes passing the assembly between rollers prior to the further lamination step.Type: GrantFiled: January 29, 1985Date of Patent: December 10, 1985Assignee: PPG Industries, Inc.Inventors: Joseph Chabal, Bruce A.
