20130219968 | GLASS FINING METHOD USING PHYSICAL BUBBLER - A method for fining a glass melt comprises providing a glass melt in a melting vessel, moving the glass melt to a fining vessel via a first channel, and physically introducing gas bubbles to the glass melt in the fining vessel to form a fined glass, wherein the melting vessel and the fining vessel are in a horizontal orientation with respect to each other. | 08-29-2013 |
20140013806 | APPARATUS FOR USE IN DIRECT RESISTANCE HEATING OF PLATINUM-CONTAINING VESSELS - An apparatus for use in controlling a temperature of an oblong-shaped molten glass-carrying vessel, such as a conduit for transporting the molten glass from one location to another location, by flowing a current through the vessel. The apparatus comprises a metal flange comprising a plurality of electrically-conductive rings that include an inner ring joined to the vessel's exterior wall and an outer ring surrounding the inner ring. The inner ring, for example, may include an outer perimeter that is substantially oblong. In some embodiments the inner ring comprises a notch that aids in making current density more uniform. In some examples the width of the inner ring, excluding the notch, does not substantially vary as a function of angular position relative to the vessel. | 01-16-2014 |
20140117017 | STIR CHAMBERS FOR STIRRING MOLTEN GLASS AND HIGH-TEMPERATURE SEALING ARTICLES FOR THE SAME - Stir chambers for stirring molten glass are disclosed. The stir chambers include a support frame, a sealing article, and a removable cover panel. The stir chambers also include a gland coupled to one of the support frame or the removable cover panel, and into which the sealing article is inserted. The stir chambers further include a seal land coupled to one of the support frame or the removable cover panel. The sealing article includes a plurality of ceramic filaments bundled together to form a core portion and a jacket portion that includes a plurality of ceramic filaments woven together. The removable cover panel is coupled to the support frame such that at least a portion of the seal land is positioned inside the gland to compress the sealing article. | 05-01-2014 |
