Publication number: 20100192633Abstract: 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).Type: ApplicationFiled: October 23, 2009Publication date: August 5, 2010Inventors: Gilbert DeAngelis, Raymond E.

Publication number: 20090217708Abstract: A substantially-isolated/controlled, limited-volume, gas-filled space (e.g., 113b) is formed over at least one free (open) surface of flowing molten glass in a manufacturing line used to produce glass sheets (137), e.g., a manufacturing line employing the fusion process to produce glass sheets suitable for use as substrates for liquid crystal displays. At least a portion of the space comprises a platinum-group metal, e.g., a platinum-rhodium alloy, which can serve as a source of platinum-group condensate defects. The use of the substantially-isolated/controlled, limited-volume, gas-filled space substantially reduces the level of such platinum-group condensate defects in the glass sheets, e.g., by more than 50%.Type: ApplicationFiled: November 6, 2008Publication date: September 3, 2009Inventors: Gilbert DeAngelis, Aaron J.

Patent number: 6993936Abstract: A system and method for suppressing the formation of gaseous inclusions in glass sheets and the resulting glass sheets are described herein. The system includes a melting, fining, delivery, mixing or forming vessel that has a refractory metal component (e.g., platinum component) which has an inner wall that contacts molten glass and an outer wall coated with an oxygen ion transportable material (e.g., zirconia) which is coated with a conductive electrode. The system also includes a DC power source that supplies DC power across the oxygen ion transportable material which causes oxygen ions to migrate from the refractory metal component to the conductive electrode and enables one to control the partial pressure of oxygen around an exterior of the vessel which helps one to effectively prevent hydrogen permeation from the molten glass in order to suppress the formation of undesirable gaseous inclusions and surface blisters within the glass sheet.Type: GrantFiled: September 4, 2003Date of Patent: February 7, 2006Assignee: Corning IncorporatedInventors: Paul R.
