Abstract: Apparatus (20) for delivering a newly formed floating glass sheet from a molten metal bath container (22) including a linear induction motor (24) that permits horizontal delivery without bath overflow is disclosed as including a gas support (34) and a drive roll (42) that cooperate with each other. The gas support (34) supports the horizontally delivered glass sheet strip by upwardly directed pressurized gas delivered between lateral edge portions (38) of the strip at a location immediately adjacent the bath container (22). The drive roll (42) is located downstream from the molten metal bath (24) and has spaced drive portions (44) that rotatively drive the lateral edge portions (38) of the glass sheet strip without the drive roll engaging the strip between the spaced drive portions. Gas support (34) preferably includes a first manifold (46) that supplies an upwardly directed inert gas and also preferably includes a second manifold (50) that supplies products of combustion from a gas burner.

Abstract: Apparatus (38) and a method for forming a flat glass sheet is disclosed as utilizing a heating conveyor (42) that transfers a heated flat glass sheet to a downwardly facing surface (46) of a topside transfer device (44), a lower mold (48) having an upwardly facing full surface (50) at least a portion of which has an upwardly convex shape that receives the heated flat glass sheet from the topside transfer device, and an upper ring mold (52) that forms and seals the periphery of the heated glass sheet against the vacuum mold surface (50) at which a vacuum is supplied within the sealed periphery of the glass sheet to form the entire extent of the glass sheet to the vacuum mold surface. A vacuum is then provided within a vacuum chamber (122) of the upper ring mold (52) to receive the formed glass sheet from the lower vacuum mold for support by the upper ring mold. A cooling mold (132) which may either be an annealing ring (132a) or a quench ring (132b) is also preferably provided to receive the formed glass sheet from the upper ring mold (52) for cooling in order to provide either annealing or tempering of the formed glass sheet.

Abstract: Provided is a support assembly for mounting an array of photovoltaic panels to a support surface such as the ground. According to the invention, there is provided a plurality of front and rear support posts, each post having an anchor portion to be driven into the support surface and a leg portion which is nested therein and longitudinally adjustable to raise or lower corresponding front and rear horizontal supports. Photovoltaic panels are mounted lengthwise across the horizontal supports in a predetermined position to minimize the stress thereon caused by wind load. The horizontal supports further comprise wiring raceways to support wiring harnesses originating from the photovoltaic panels and terminating at the end of each row of photovoltaic panels in the array.

Abstract: A glass sheet tempering method and resultant glass sheet are disclosed as being provided by modulated quenching that initially cools oppositely facing surfaces of a conveyed glass sheet (G) at a first cooling station (14) with a first rate of heat transfer for a finite time to cool the surfaces from tempering temperature to below the strain point without cooling the center of the glass sheet below the strain point. Thereafter the oppositely facing surfaces of the conveyed glass sheet are cooled within a second cooling station (15) at a second rate of heat transfer less than the first rate to initially cool the center of the glass sheet below the strain point without corresponding surface cooling, and thereafter to cool the center and the surface. The modulated quenching provides a relatively large ratio of surface compression to center tension without excessive magnitudes of stress.

Abstract: A glass sheet gas support (20) is disclosed as having a set of elongated gas supply openings (26) for supplying pressurized gas to support a glass sheet and as also including a set of elongated gas exhaust openings (28) for exhausting the gas and constructed to include progressively increasing gas flow areas in opposite directions from ends (36) of each exhaust opening to a central portion (38) thereof in order to prevent gas pressure buildup between an upwardly facing surface (24) of the manifold and the supported glass sheet at a central location. In one embodiment, the manifold (22) defines each gas exhaust opening (28) with progressively increasing widths from its ends (36) toward the central portion (38) thereof and is preferably constructed as a cast refractory platen (42) which cooperates with a manifold member (58) that mounts gas jet pumps (60) fed products of combustion from a gas burner (62) to provide recirculating flow of gas to and from the supply exhaust openings.
