20090126405 | SYSTEM AND METHOD FOR CONTROLLING THE ENVIRONMENT AROUND ONE OR MORE VESSELS IN A GLASS MANUFACTURING SYSTEM - A system and method are described herein that control the environment (e.g., oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s). | 05-21-2009 |
20090142608 | Method for bonding refractory ceramic and metal - A method is disclosed for mechanically bonding a metal component to a ceramic material, comprising providing a metal component comprising an anchor material attached to at least a first portion of one surface of the metal component; providing a ceramic material having a first surface and a second surface, wherein the ceramic material defines at least one conduit extending from the first surface to the second surface, wherein the at least one conduit has a first open end defined by the first surface, a second open end defined by the second surface, a continuous sidewall and a cross sectional area; positioning the ceramic material such that at least a portion of the at least one conduit is in overlying registration with at least a portion of the anchor material; and applying a bonding agent into at least a portion of the at least one conduit. | 06-04-2009 |

20120275483 | ELECTRODE HOLDER FOR ELECTRIC GLASS MELTING - An electrode holder for use in a furnace for melting a batch material to form molten glass is disclosed comprising a refractory coated nose member presented to and in contact with a molten glass material contained within the furnace. The refractory coating is preferably a flame- or plasma-sprayed ceramic such as alumina or zirconia. That protects the nose member from corrosion from the hot molten glass. | 11-01-2012 |
20130025323 | FIBER-BASED GASKET, GLASS MANUFACTURING SYSTEM, AND METHOD FOR REDUCING THERMAL CELL INDUCED BLISTERS - A fiber-based gasket, a glass manufacturing system, and a method are described herein for reducing thermal cell induced blisters. In one embodiment, the fiber-based gasket is placed in a connection between a first glass manufacturing device (e.g., capsule surrounding a downcomer) and a second glass manufacturing device (e.g., fusion draw machine surrounding an inlet). The fiber-based gasket has a density and compression which results in a gas permeation rate per unit surface area that is less than 22.5 ml/min/cm | 01-31-2013 |
20130025379 | GLASS SAMPLING APPARATUS AND METHOD FOR USING SAME TO OBTAIN A GLASS SAMPLE FROM A GLASS MELTING VESSEL - A glass sampling apparatus and a method for using the glass sampling apparatus to obtain a glass sample from molten glass within a glass melting vessel are described herein. In one embodiment, the glass sampling apparatus includes: (a) a sampling tube having a first end and a second end, where the second end is used to obtain the glass sample from the molten glass in the glass melting vessel; (b) a first valve; (c) a vacuum device; and (d) a tube network that couples the first end of the sampling tube to both the first valve and the vacuum device. | 01-31-2013 |
