| 20080202167 | Thermal edge finishing - A thermal edge finishing process includes preheating at least one cut edge of a glass sheet, laser finishing the edge to a single full continuous radius from a position orthogonal to the edge and in-plane with the glass sheet while continuing to heat the glass, and localized annealing of the edge to reduce residual stress from the laser/thermal treatment of the edge. By the present process, edge stress is reduced considerably, such as to less than 3000 psi, and more preferably to less than 2500 psi, and to as low as 1000 psi in the first 1 mm along the treated edge. | 08-28-2008 |
| 20090041982 | Opaque chrome coating suitable for etching - A substrate includes an opaque chrome coating on a surface of the substrate dry-etched to form an aperture, wherein chrome in the aperture is below detectable limit. | 02-12-2009 |
| 20090294419 | Scoring of non-flat materials - Disclosed are systems for scoring non-flat materials including non-flat glass sheets ( | 12-03-2009 |
| 20100000259 | METHOD OF MAKING SHAPED GLASS ARTICLES - In a method of making shaped glass articles, a glass sheet is placed on a mold having a shaping surface with a desired surface profile of a shaped glass article. The glass sheet is preferentially and rapidly heated by radiation while in the vicinity of the mold so that the mold remains substantially cooler than the glass sheet during the heating. The glass sheet is sagged onto the shaping surface of the mold so that at least a portion of the sagged sheet assumes the desired surface profile of the shaped glass article. After sagging and shaping, the sagged and shaped glass sheet is removed from the mold. | 01-07-2010 |
| 20100055395 | Method of Making Shaped Glass Articles - A method of making a shaped glass article includes applying a compression load to a surface of a glass sheet such that the compression load is distributed along a non-quality area of the glass sheet, wherein said non-quality area of the glass sheet circumscribes and adjoins one or more quality areas of the glass sheet. The method further includes holding the compression load against the surface of the glass sheet for a predetermined time during which a thickness of the glass sheet beneath the non-quality area decreases and the quality area protrudes outwardly relative to the surface of the glass sheet to form the shaped glass article. | 03-04-2010 |
| 20100313877 | SOLAR HEAT COLLECTION ELEMENT WITH GLASS-CERAMIC CENTRAL TUBE - A solar heat collection element includes: a central tube ( | 12-16-2010 |
| 20110126588 | METHOD AND APPARATUS FOR MAKING A SHAPED GLASS ARTICLE - A flat glass sheet and a mold having a mold cavity defined by a shaping surface are provided. The shaping surface has a surface profile of a shaped glass article. At least one edge alignment pin is provided on the mold at an edge of the shaping surface. The glass sheet is leaned against the edge of the shaping surface such that an edge of the glass sheet abuts the edge alignment pin. The glass sheet is then heated. The glass sheet is sagged onto the shaping surface of the mold so that the glass assumes the surface profile of the shaped glass article and thereby form the shaped glass article. The edge alignment pin aligns the edge of the glass sheet with the mold cavity as the glass sheet sags onto the shaping of the mold. The shaped glass article is removed from the mold. | 06-02-2011 |
| 20110129650 | METHOD FOR IMPROVING THE EDGE STRENGTH OF TEMPERED GLASS SHEET ARTICLES - A tempered glass sheet article includes a glass sheet having a thickness t, at least one edge, and at least one surface. The at least one edge is connected to the at least one surface by an edge-to-surface corner. The edge-to-surface corner is rounded with a radius r and has a surface compression that is at least 78% of a surface compression measured at or near a center of the at least one surface. | 06-02-2011 |
