Patent number: 4910088Abstract: A vehicle window 100 comprises a glass sheet 101 bearing a coating 102. The coating 102 is a tin oxide coating located on an external face of the vehicle window, and has been polished after deposition.Such a coating can confer increased abrasion resistance, and facilitates removal of frozen condensation. The coating may be electrically conductive so that it reduces the emissivity of the coated face in respect of infra-red radiation having wavelengths greater than 3 micrometers.A method of manufacturing a transparent vehicle window is disclosed which comprises depositing a coating on a face of a piece of glass in sheet or ribbon form, the coating deposited being a tin oxide coating. After deposition the coating is subjected to a polishing treatment.Type: GrantFiled: October 16, 1987Date of Patent: March 20, 1990Assignee: GlaverbelInventors: Pol Baudin, Jean F. Thomas

Patent number: 4842664Abstract: A process of imparting a predetermined curvature to a sheet of thermoplastics material in which a thermoplastics sheet is bent by placing it against a face of a bending form. The form having a moulding surface area of the required curvature. The process includes heating the thermoplastics sheet and causing or allowing it to conform to the moulding surface area. The thermoplastics sheet is formed oversized and is bent by placing it against a bending form having a moulding surface area portion of the required dimensions and curvature which is surrounded by a bending form surround. Next, the thermoplastics sheet is heated and caused or allowed to conform to the moulding surface area portion while its oversized margins are supported by the bending form surround. Thereafter, the thermoplastics sheet is cooled at a rate slow enough to maintain such conformity, and then the thermoplastics sheet is trimmed to size.Type: GrantFiled: August 10, 1987Date of Patent: June 27, 1989Assignee: GlaverbelInventor: Pol Baudin

Patent number: 4249958Abstract: In order to reduce or prevent absorption of water in the adhesive of a panel comprising at least one photovoltaic cell located between a transparent sheet and a second sheet bonded together using an adhesive material, the invention provides that another material is applied at least in part between the sheets to form a moisture barrier which surrounds the cell(s) and the adhesive.The preferred adhesive material is polyvinyl butyral, and the preferred barrier forming material is selected from neoprene based adhesives, polysulphide adhesives and polyvinylidene chloride. When the latter is used a second barrier forming material such as polysulphide adhesive is preferably interposed between the adhesive and the polyvinylidene chloride.Type: GrantFiled: June 7, 1979Date of Patent: February 10, 1981Assignee: BFG GlassgroupInventors: Pol Baudin, Lucien Leger, Pierre Collignon

Patent number: 3930452Abstract: An impact resistant panel composed of a group of at least three sheets of vitreous material bonded together via intervening layers of plastic material. According to one form of construction, the group includes a set of consecutive vitreous sheets of at least three different thicknesses which are arranged in order of thickness, and at least the first sheet, taken in the direction from the highest sheet thickness end of the set, is tempered. According to a second form of construction, the group includes a set of consecutive sheets of at least two different thicknesses arranged in order of thickness and at least two of the plastic layers are of different thicknesses and are arranged so that one of the layers having the smallest thickness is nearer the first sheet, taken in the direction from the thickest sheet, than is any other layer.Type: GrantFiled: September 19, 1973Date of Patent: January 6, 1976Assignee: Glaverbel-Mecaniver S.A.Inventors: Robert Van Laethem, Pol Baudin, Marcel De Boel
