Patent number: 9076901Abstract: The invention relates to a process for producing a glass sheet 10, 21 coated with a semiconductor material, which comprises the steps (a) production of a glass strip in a float bath 3 containing liquid tin; (b) discharge of the glass strip from the float bath 3 and optionally coating of the glass strip with a transparent, electrically conductive intermediate layer; (c) transfer of the uncoated or coated glass strip into a deposition chamber 5 for the physical deposition of the semiconductor material from the gas phase; and (d) coating of the coated or uncoated glass strip from step (c) with the semiconductor material by physical deposition of the semiconductor material from the gas phase at a gas pressure of at least 0.1 bar. The invention additionally relates to an apparatus for producing a glass strip coated with a semiconductor material, a process for producing a solar cell or a solar module and also a solar cell or a solar module which can be obtained by this process.Type: GrantFiled: April 20, 2011Date of Patent: July 7, 2015Assignee: Calyxo GMBHInventors: Frank Becker, John Bohland, Hubert Joachim Frenck, Michael Bauer, Robert Fischer, Kenneth R. Kormanyos, Norman W. Johnston

Patent number: 4951927Abstract: An encapsulated multiple glazed structure is formed by positioning at least two spaced apart substantially coextensive sheets of glazing material wherein the sheets are maintained in aligned spaced relation by a suitable spacer element adjacent the peripheral portions of the facing surfaces of the glazing sheets. The above assemblage is then typically placed within a mold cavity of a suitable molding apparatus and a charge of an elastomeric gasket forming material is injected therein to form an encapsulating gasket around the peripheral edge portions of the assemblage to produce a multiple glazed structure.Type: GrantFiled: February 15, 1989Date of Patent: August 28, 1990Assignee: Libbey-Owens-Ford Co.Inventors: Norman W. Johnston, Edward W. Curtze

Patent number: 4813198Abstract: A variable solar control window assembly includes a pair of spaced parallel planar transparent sheets mounted in a frame. An induced transmission filter sheet is selectively movable between the transparent sheets for varying the solar transmission through the window assembly. The filter sheet includes a carrier layer and one or more coating layers, each coating layer formed as a layer of reflective metal material between two layers of dielectric material. The filter sheet can have bearing/protective layers or strips adhered thereto to seal against the frame and to assist in the sliding movement of the filter sheet with respect to the frame. One or both of the transparent sheets can include an anti-lacerative material layer.Type: GrantFiled: November 23, 1987Date of Patent: March 21, 1989Assignee: Libbey-Owens-Ford Co.Inventors: Norman W. Johnston, Darryl J. Costin

Patent number: 4712287Abstract: A method of assembling a vehicle includes the steps of forming a plurality of different modular window assemblies each having at least one sheet of transparent material upon which a gasket has been formed. A windshield module can include a peripheral gasket, integral leaf screen and a hinged sun roof. A door module can include a peripheral gasket and bracket attached to a window installed in a door. A rear window module can include hinged side windows and a roof panel. After the modules have been formed, they are then assembled to a vehicle body.Type: GrantFiled: May 23, 1986Date of Patent: December 15, 1987Assignee: Libbey-Owens-Ford Co.Inventor: Norman W.
