Filed:

Oct 16, 2007

Appl. No.:

11/974873

Inventors:

Steven R Burdette - Big Flats NY, US
Raymond E Fraley - Waverly NY, US
Steven R Wagner - Danville KY, US

Assignee:

Corning Incorporated - Corning NY

International Classification:

C03B 5/18

US Classification:

651352, 651353, 65346, 65178

Abstract:

The present invention is directed toward a method of reducing contamination of a glass melt by oxide particulates, such as particulates of platinum oxide, which may condense on the inside surfaces of a stir chamber, particularly the stir shaft, and fall back into the glass melt. The method includes causing a flow of gas through an annular space between the shaft and the chamber cover. In one embodiment, the flow of gas through the annular space is caused by drawing a vacuum in the chamber. An apparatus for practicing the method is also provided.

International Classification:

C03B 5/20
C03B 5/18

US Classification:

651351, 651341

Abstract:

An oblong conduit () for conditioning molten glass is disclosed. The wall () of the conduit is composed of a precious metal, e. g. , a platinum-rhodium alloy, and can be equipped with precious metal tabs () for supporting the upper surface () of the wall so as to reduce sag of that surface at such times as the conduit is at an elevated temperature and is not filled with glass. The precious metal tabs () can be received in channels () formed in a refractory support structure (). The refractory support structure () can be a laminate of two layers (), where one of the layers () has a smaller grain structure than the other layer (), the layers being held together by an adhesive ().

International Classification:

C03B 5/00
C03B 5/16

US Classification:

065134100, 065134400

Abstract:

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).

International Classification:

C03B 13/00
C03B 5/26

US Classification:

65 90, 65324

Abstract:

The present invention provides an improved apparatus for forming sheet glass, wherein the apparatus includes a reservoir from which to provide molten glass, an inlet plate in fluid communication with the reservoir to receive the molten glass from the reservoir in a flow direction, the inlet pipe having a cross-sectional area orthogonal to the fluid direction, and a trough in fluid communication with the inlet pipe to receive the molten glass and that is operably coupled to a wedge-shaped sheet forming structure to form the molten glass into a glass sheet. The improvement comprises a bowl that provides fluid communication between the inlet pipe and the trough, the bowl having a cross-sectional area orthogonal to a fluid direction at the molten through the bowl that is equal to or less than the cross-sectional area of the inlet pipe, thereby preventing stagnation of the molten glass within the bowl. Another embodiment of the present invention is a method that utilizes the inventive apparatus to form glass sheet.

US Classification:

651356, 651341, 651364, 65347

Abstract:

A glass making process comprising a step of fining the molten glass in a fining vessel comprising a top wall portion not in direct contact with the molten glass, and a side wall portion in direct contact with the molten glass, wherein the top wall portion has a temperature T(top), the side wall portion has a temperature T(side), and T(top)−T(side)≦10 C., and a glass fining system. The invention is particularly useful for glass fining systems comprising a metal fining vessel made of precious metals such as Pt and/or Pt—Rh alloys.
