| 20120186302 | GLASS LATHE - Provided is a glass lathe that processes a glass member by heating the glass member with a burner, wherein a reflector that reflects electromagnetic waves is arranged around a portion of the glass member to be heated. The reflector preferably has a spherical surface with a portion removed therefrom, and may be formed of a mirror surface finishing agent for SUS, aluminum, or an aluminum alloy. An inner surface of the reflector is preferably covered by gold, platinum, or rhodium, and an outer surface of the reflector is preferably processed to improve thermal emittance, by applying an infrared light emitting coating thereto. | 07-26-2012 |

| 20160145142 | METHOD FOR REDRAWING OF GLASS - A drawing method for glass is described. The method provides glass components that have a strongly increased ratio of width to thickness when compared to the preform, which makes the manufacturing of flat glass components more economical. The method purposefully controls the temperature distribution within the preform. | 05-26-2016 |

| 20080209947 | APPARATUS FOR BENDING A GLASS SHEET - A glass sheet is heated to a forming temperature in a heating furnace, the heated glass sheet is conveyed along a conveying plane defined by a plurality of rollers of a roller conveyer, and is moved up and down on the rollers according to the position of the glass sheet to curve a part of the conveying plane with respect to the glass sheet conveying direction to bend the glass sheet to have a desired curvature by its own weight. The rollers are curved rollers. | 09-04-2008 |
| 20130125592 | METHODS AND APPARATUS FOR LOCALIZED HEATING AND DEFORMATION OF GLASS SHEETS - Methods and apparatus provide for: an electrically conductive heating element having a length extending in a lateral direction between first and second ends, and one or more output surfaces operating to direct heat therefrom in a direction transverse to the lateral direction; and a carrying structure operable to support a glass sheet such that a major surface of the glass sheet is oriented towards the heat emanating from the one or more output surfaces of the heating element, where the electrically conductive heating element includes at least one heat flux variation feature operating to produce differing magnitudes of heat to emanate from at least two of the output surfaces of the heating element. | 05-23-2013 |
| 20130160495 | HEAT-REGULATING GLASS BENDING APPARATUS AND METHOD - A sag-bending system is disclosed. The sag-bending system comprises a sag-bending glass support mold and a perimeter thermal manager. The support mold comprises a plurality of rib members extending in a first direction, each of the plurality of rib members having a curved upper surface shaped to form the collective upper surface having a position and shape to support a quadrilateral-shaped sag-bent glass sheet into a desired contour, each of the rib members further having a lower surface, and a plurality of support members extending in a second direction between at least two of the plurality of rib members, the second direction traverse to the first direction. The perimeter thermal manager is sized and positioned to surround, to extend at least partially over, and to extend at least partially under the periphery of the support mold. | 06-27-2013 |
| 20140352360 | THERMO-MECHANICAL REFORMING METHOD AND SYSTEM AND MECHANICAL REFORMING TOOL - A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area. | 12-04-2014 |
