Patent number: 5026414Abstract: A plurality of glass plates are positioned under upper units capable of bending and/or transferring those plates, the pick up and release of each plate being independent of each other. The plates are bent either on the upper station, or on a lower unit onto which they are released from the upper station. The plates are subsequently subjected to tempering. Mass production of tempered glass plates at both high quality and high output levels is thus achieved.Type: GrantFiled: January 16, 1990Date of Patent: June 25, 1991Assignee: Saint-Gobain VitrageInventors: Denis Mathivat, Daniel Colmon, Daniel Philibert

Patent number: 5006146Abstract: Apparatus for bending glass plates provides a conveyor of serverable sections, each of which feeds glass plates to separate stations for bending the glass plates, the glass plates having first passed through a reheating furnace. The stations for bending or transfer employ a common upper unit, which is provided with a plurality of means for retaining the glass by aspiration under a vacuum. Each means for retaining the glass plate, and vacuum means associated therewith, is operable independently, such that the glass plates can be aspirated and released at each station independently of the actions of the remaining stations. After having been bent or shaped either on the upper retaining means, or lower bending units provided thereunder, the glass plates may be subjected to temper. Mass production of bent or shaped, and tempered, glass plates, with high, reproducible quality, and varying requirements, is made possible through such a system.Type: GrantFiled: November 6, 1987Date of Patent: April 9, 1991Assignee: Saint-Gobain VitrageInventors: Denis Mathivat, Daniel Colmon, Daniel Philibert

Patent number: 4936890Abstract: The invention concerns the use of a convexing/tempering installation for the manufacture of flat sheet glass or, in general, of glass not bent into convex shape on said installation. It proposes passing glass plates are passed through a conventional convexing/tempering installation, omitting the convexing operation, providing additional heating in the space initially set aside for convexing and/or modifying the tempering conditions initially provided for glass bent into convex shape in said installation. It makes it possible to take advantage of a given convexing/tempering installation for manufacturing tempered flat sheet glass or for heating glass plates with a view to having them bent into convex shape in another installation.Type: GrantFiled: November 6, 1987Date of Patent: June 26, 1990Assignee: Saint-Gobain VitrageInventors: Daniel Colmon, Bernard Parnet, Alain Mercier, Claude Bourelier

Patent number: 4773926Abstract: The invention relates to air tempering of glass in flat tempering installations. It proposes blowing air, particularly at sonic speed, with nozzles, preferably tubular, slightly distant from the glass, exhibiting the maximum loss of pressure at their free end close to the glass. It makes possible the tempering, under economically advantageous conditions, of glass sheets having thicknesses less than 2 mm and all the more so, glass sheets having greater thicknesses, which can be used as glasses, particularly windshields, for motor vehicles.Type: GrantFiled: July 30, 1986Date of Patent: September 27, 1988Assignee: Saint-Gobain VitrageInventors: Bernard Letemps, Daniel Colmon

Patent number: 4749401Abstract: In glass tempering using a cooling gas, the impact of gas jets on glass is modified through the use of perturbations to which said jets are subject. The perturbations may be introduced laterally with respect to the tempering jets, and spaced from the opening providing said tempering jets. The characteristics of the perturbations vary cyclically. The invention makes it possible to obtain homogeneous tempering, even for highly bulged glass sheets.Type: GrantFiled: August 27, 1987Date of Patent: June 7, 1988Assignee: Saint-Gobain Vitrage "Les Miroirs"Inventors: Daniel Colmon, Bernard Letemps
