| 20110126595 | FOREHEARTH OR WORKING-END FOR GLASS FURNACE AND PROCEDURE FOR THE EXTRACTION OF FUMES FROM THE FOREHEARTH - A forehearth ( | 06-02-2011 |
| 20120017643 | MELTING DEVICE FOR PRODUCING A GLASS MELT - A glass melting oven for producing a glass melt in a row arrangement, having a loading opening for raw glass materials, a melting region, a refining region, a constriction, a conditioning region and an overflow into a processing unit. To remove flaws from the melt that remain visible in the end product, a method includes the steps of a) arranging a refining bench between the melting region and the beginning of the refining region; b) arranging side burners and extraction openings for flue gases between the loading opening and the refining bench; c) delimiting the constriction at both ends by end walls that leave narrow flow cross-sections above the glass melt for flue gases; and d) cooling the glass melt inside the constriction. The glass melting oven is particularly suited for producing flat glass and panels for solar elements. The oxidants for the fuels may also be preheated. | 01-26-2012 |
| 20130031936 | METHOD FOR RE-ESTABLISHING THE SYMMETRICAL TEMPERATURE PROFILE AT THE EXIT FROM A BEND IN A FEEDER, AND FEEDER FOR IMPLEMENTING THE METHOD - A method for re-establishing or tending to re-establish symmetrical distribution of temperatures between right-hand and left-hand sides of a cross section of a flow of molten glass that has been routed in a feeder including at least one bend area, thermal asymmetry having been induced by flowing round a bend. The feeder includes a flow channel, formed from refractory and insulative material elements and including a horizontal sole plate and two lateral walls, and a vault capping the channel, formed of a refractory roof and lateral parts including burners. In an area of each bend, the flow channel is modified by choosing a corresponding inclined sole plate portion, the inclination being chosen so that the flow channel is deeper in an outside region of the bend than in its inside region, heights of the two lateral walls of the channel being modified accordingly. | 02-07-2013 |
| 20130133372 | GLASS FLOW MANAGEMENT BY THERMAL CONDITIONING - This disclosure relates to methods and apparatus for controlling glass flow in, for example, a downdraw glass manufacturing process (e.g., the fusion downdraw process). The methods and apparatus are particularly well-suited for use in the manufacture of glass sheets such as the glass sheets used as substrates in display devices, e.g., liquid crystal displays (LCDs). | 05-30-2013 |
| 20130283861 | SUBMERGED COMBUSTION MELTER COMPRISING A MELT EXIT STRUCTURE DESIGNED TO MINIMIZE IMPACT OF MECHANICAL ENERGY, AND METHODS OF MAKING MOLTEN GLASS - A melter apparatus includes a floor, a ceiling, and a wall connecting the floor and ceiling at a perimeter of the floor and ceiling, a melting zone being defined by the floor, ceiling and wall, the melting zone having a feed inlet and a molten glass outlet positioned at opposing ends of the melting zone. Melter apparatus include an exit end having a melter exit structure for discharging turbulent molten glass formed by one or more submerged combustion burners, the melter exit structure fluidly and mechanically connecting the melter vessel to a molten glass conditioning channel. The melter exit structure includes a fluid-cooled transition channel configured to form a frozen glass layer or highly viscous glass layer, or combination thereof, on inner surfaces of the fluid-cooled transition channel and thus protect the melter exit structure from mechanical energy imparted from the melter vessel to the melter exit structure. | 10-31-2013 |
| 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 |
| 20140123710 | APPARATUS AND METHOD FOR MINIMIZING PLATINUM GROUP METAL PARTICULATE INCLUSION IN MOLTEN GLASS - An apparatus used in the production of glass, and a process for minimizing the inclusion of platinum group metal particulate into molten glass during glass production are provided, the apparatus comprising a first conduit formed of a platinum group metal, the first conduit comprising a top wall portion, a side wall portion, an outer surface, and a length, and a heat sink formed of a platinum group metal and affixed continuosly to the outer surface and extending longitudinally along at least part of the length of the first conduit proximate the top wall portion for the dissipation of heat therefrom, wherein the inner volume has a maximum temperature, T(max inside top wall), and the inner surface proximate the heat sink has a lower temperature, T(min inside top wall), and wherein platinum group metal particulate formed during the production process will deposit on the inner surface area of the top wall portion not in contact with the molten glass. | 05-08-2014 |
| 20150107306 | APPARATUS AND METHODS FOR PRODUCING GLASS RIBBON - An apparatus for producing glass ribbon comprises a melting vessel configured to melt a batch of material into a quantity of molten glass. The apparatus includes a cooling conduit with a peripheral wall comprising platinum and defining an interior pathway configured to provide a travel path for the quantity of molten glass traveling from the first conditioning station to the second conditioning station. The peripheral wall includes an outer surface defining a plurality of elongated radial peaks spaced apart by a plurality of elongated radial valleys. The elongated radial peaks and elongated radial valleys are helically wound along an elongated axis of the cooling conduit. In further examples, methods are provided with the step of passing molten glass through the interior pathway of the cooling conduit to pass the molten glass from the first conditioning station to the second conditioning station. | 04-23-2015 |
