A method for reducing alkali vapor corrosion of glass furnace refractory structures includes providing a gas inlet proximate to the oxy-fuel combustion region; introducing a volume of gas from the inlet into the region, displacing a volume of gas having a partial pressure of alkali vapor from the region; and, optionally providing a gas outlet adapted to provide an exit for a volume of furnace atmosphere.Type: GrantFiled: January 24, 2007Date of Patent: March 2, 2010Assignee: Linde LLCInventors: Neil George Simpson, John R. LeBlanc, Gregory Floyd Prusia

Patent number: 7647791Abstract: A composite mold includes a mold base, a protective film provided on the mold base, and a water-cooling heat dissipation system disposed within the mold base. Wherein, the protective film is comprised of with a plurality of RexIry layers and a plurality of SiC layers, the RexIry layers and the SiC layers are alternatively stacked one on another, x is in the range from 0.25 to 0.55, and y is in the range from 0.45 to 0.75. Alternatively, the protective film is comprised of an RexIry layer, a catalyst layer and a carbon nanotube layer in that order, x is in the range from 0.25 to 0.55, and y is in the range from 0.45 to 0.75.Type: GrantFiled: December 5, 2005Date of Patent: January 19, 2010Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Charles Leu

Publication number: 20090277226Abstract: A method and system that uses a cold wall furnace for melting the materials that are feed into the furnace. In one aspect, at least a portion of the exterior surface of the cold wall furnace is surrounded by at least one jacket configured to transfer heat away from the metal liner of the furnace. This cooling causes the molten glass to solidify on the metal surface of the metal liner of the cold wall furnace, which acts to protect the metal liner of the furnace from oxidation during molten glass evacuation and subsequent exposure to atmosphere.Type: ApplicationFiled: October 16, 2008Publication date: November 12, 2009Inventors: Salvatore R. Santangelo, Steven D. Hummel

Publication number: 20090235695Abstract: A furnace for melting batch materials, including, upstream in the direction of flow of the molten materials, a zone for introducing solid batch materials, and including a submerged burner and an overhead surface burner providing a flame that touches the surface of the glass at the point where the bubble from the submerged burner emerges. This association of an overhead, especially roof-mounted, burner and a submerged burner reduces the quantity of batch stones that may be sent toward the downstream end of the furnace.Type: ApplicationFiled: April 4, 2007Publication date: September 24, 2009Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Laurent Pierrot, Frederic Lopepe, Biagio Palmieri, Laurent Joubaud, Philippe Pedeboscq, Philippe Meunier

Publication number: 20090214998Abstract: A burner for fabricating an optical fiber preform, which can suppress the adhesion and deposition of glass particles to the front end of the burner without enlarging the burner diameter, is provided. The burner has a first tube, a second tube and a third tube coaxially arranged and define a glass raw material gas port, a sealing gas port, and a burnable gas port by the front end portions thereof, and a plurality of small diameter nozzles arranged between the second tube and the third tube, each of the nozzles arranged on a concentric circle relative to the glass raw material gas port and defines a combustion assisting gas port by the front end portion thereof, the front end portion of the second tube protrudes ahead of that of the first tube, and the front end portion of the third tube protrudes ahead of those of the second tube and each of the nozzles.Type: ApplicationFiled: February 27, 2009Publication date: August 27, 2009Applicant: SHIN-ETSU CHEMICAL CO., LTD.Inventor: Makoto YOSHIDA

Publication number: 20090176639Abstract: The invention relates to a furnace for continuously melting a silica-containing compound comprising at least two series-arranged baths each of which is provided with at least one burner submerged into molten material. Said invention also relates to a method for producing silica-containing compounds, the silica and the melt thereof being loaded into the first bath. The invention is intentionally adapted for the high performance production of frits for re-enameling ceramic products (sandstone, faience and burnt clay) at low temperatures and a fast transition time.Type: ApplicationFiled: July 26, 2005Publication date: July 9, 2009Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Remi Jacques, Jerome Lalande, Laurent Teyssedre

Patent number: 7322215Abstract: Methods for press molding a glass body, especially for optical applications, without additional grinding and polishing steps are described. One method is performed with a press mold having an upper mold part, a lower mold part and, if necessary or desired, a ring. In order to improve the quality of the products, especially glass bodies of larger diameters, a voltage is applied across the upper mold part and the lower mold part when the glass body is within the press mold and a pressing force is applied to the glass body when the temperature of the glass body matches the temperature of the press mold. Alternatively, in another method the press mold is cooled after it reaches a predetermined temperature and the pressing force is applied to the glass body in the mold after exceeding the sticking temperature (T0).Type: GrantFiled: July 23, 2003Date of Patent: January 29, 2008Assignee: Schott AGInventors: Ulrike Stoehr, Ralf Biertuempfel, Wolfgang Semar

Patent number: 7313931Abstract: After carrying an LCD substrate in a reaction container of a heat treatment unit, blowing a previously heated helium gas from a gas supply part, which opposes to the surface of the LCD substrate, over the entire surface of the LCD substrate. The temperature of the LCD substrate is raised by radiation heat of a heater and heat exchange with the helium gas. After performing CVD or annealing in the reaction container, cooling the LCD substrate by blowing a gas for heat exchange having a temperature about a room temperature from the gas supply part over the entire surface of the LCD substrate. Return the cooled LCD substrate to a carrier in the carrier chamber via a conveyance chamber.Type: GrantFiled: August 26, 2005Date of Patent: January 1, 2008Assignee: Tokyo Electron LimitedInventor: Takaaki Matsuoka
