Abstract:
A method of a drawing a glass ribbon from molten glass sheet via a downdraw process by creating a temperature drop across a thickness of the molten glass flowing over forming surfaces of a forming wedge. The forming wedge includes an electrically conductive material for heating the glass above the root.
Abstract:
A glass manufacturing system (100, 100', 100'') and method are described herein for forming a high quality thin glass sheet (110). In one embodiment, the glass manufacturing system and method use at least one of a compensated rolling roll (108a), a temperature controlled environment (120) and edge rolls (122, 124) to form a high quality thin glass sheet that has a thickness less than about 2mm and more preferably less than about 100 μm.
Abstract:
Disclosed are systems and methods for forming glass sheets. Methods and systems are provided that comprise a refractory body configured to receive glass-based material and means for transmitting energy to selectively heat at least a portion of the refractory body through the glass-based material. In one aspect, the energy transmitted is of a selected frequency that is not fully absorbed by the glass-based material and is at least partially absorbed by the refractory body. The energy can be transmitted by a laser beam array, a scanning laser beam, a microwave generator, a radio frequency generator, or other means.
Abstract:
Disclosed are mono- or multi-component glass-ceramic articles (10; 20; 30; 40; 50; 60; 70; 80; 90) having at least one weld joint (100), as well as a method of manufacturing such articles (10; 20; 30; 40; 50; 60; 70; 80; 90), which includes the implementation of at least one welding. The present invention is based upon mastery of the welding of glass-ceramic precursor glasses.
Abstract:
A glass forming system (200) and a method are described herein for forming a glass sheet (230). In one example, the glass forming system and method can use a glass composition with a liquidus viscosity less than 1000 poises to continuously form a glass sheet.
Abstract:
An apparatus for stabilizing a flow of a viscous material, such as a molten glass or glass ceramic material in a tube or rod forming process is disclosed. The apparatus comprises a stabilization member through which the molten glass is passed after leaving the nozzle of a forming vessel. The stabilization member is positioned a finite distance below the nozzle. The column of viscous material is supported by a wall of the stabilization member, or by a gaseous film disposed between the column and the stabilization member. A method of stabilizing the flow of viscous material after it leaves the nozzle during a drawing process is also disclosed.
Abstract:
A glass manufacturing system (100) and method are described herein that use a fusion draw process and a vertical roll apparatus (102) to manufacture a textured glass sheet (105). In one embodiment, the textured glass sheet (105) has a thickness in the range of about 0.5-3.0 mm.
