The repositionable heater assembly includes a support frame, a first sled and a second sled each coupled to the support frame with bearing members that allow the first sled and... Agent: Corning Incorporated

20140238078 - Machining of fusion-drawn glass laminate structures containing a photomachinable layer: Methods for machining glass structures may be performed on fusion-drawn glass laminates having a core layer interposed between a first cladding layer and a second cladding layer. The core layer may be formed from a core glass composition having a core photosensitivity, the first cladding layer may be formed from... Agent: Corning Incorporated

20140238079 - Glass forming apparatus and method: A glass forming apparatus and method include a weir on at least a first side of a molten core glass reservoir. The weir includes an inclined surface that, in the intended direction of molten glass flow, slopes downward in the vertical direction while extending away from the molten core glass... Agent: Corning Incorporated

20140238080 - Systems and techniques for fabricating optical fiber gratings: A resistive heating element is used to fabricate a long-period grating mode converter. The resistive heating element creates a localized heating zone for creating an asymmetric perturbation at a periodic series of axial locations along the length of a segment of optical fiber that supports the propagation of both a...

20140230490 - Methods for reducing zirconia defects in glass sheets: Methods are disclosed for treating zircon-containing forming structures, e.g., zircon isopipes, with one or more treatment glass compositions in which defect-causing reactions between the zircon of the forming structure and molten glass are suppressed at the delivery temperature of the treatment glass. The treatment compositions can be used during start-up... Agent: Corning Incorporated

20140230491 - High volume production of display quality glass sheets having low zirconia levels: Methods and apparatus for producing display quality glass sheets are provided in which the batch materials for making the sheets are melted in a furnace whose glass-engaging surfaces comprise zirconia (ZrO2). By using molybdenum electrodes, instead of the conventional tin electrodes, to electrically heat the molten glass, the wear rate... Agent: Corning Incorporated

20140230492 - Tempered glass and glass: A tempered glass of the present invention includes, as a glass composition, in terms of mass %, 45 to 75% of SiO2, 0 to 30% of Al2O3, and 0 to 30% of Li2O+Na2O+K2O and has a β—OH value of 0.3 to 1/mm.... Agent: Nippon Electric Glass Co., Ltd.

20140230493 - Method for cambering glass sheets by suction: A method and device for bending superposed sheets of glass. The sheets are picked up by a top form furnished with a suction creating an upward airflow blowing over the rim of the sheets, the suction being sufficient to lift and hold the superposed sheets against the top form, then... Agent: Saint-gobain Glass France

20140230494 - Production method of quartz glass: A method of manufacturing quartz glass includes depositing soot generated by flame hydrolysis of a raw material gas to a starting member, while the starting member is raised and rotated, to form a soot deposition member that includes an effective portion having a substantially constant outer diameter, the effective portion... Agent: Shin-etsu Chemical Co., Ltd.

20140230495 - Method for manufacturing a primary preform for optical fibres: A method for manufacturing a primary preform for optical fibres including surrounding at least part of a hollow substrate tube with a furnace set at a temperature T0, supplying doped or undoped gases to the inside of the tube, creating a reaction zone to promote deposition, and moving the zone... Agent: Draka Comteq B.v.
