Abstract:

Methods and apparatus for controlling glass flow in, for example, a downdraw glass manufacturing process (e. g. , the fusion downdraw process) are provided. In certain aspects, the mass, thickness, and/or the temperature distribution of molten glass () on the surface of forming apparatus () is managed by: (A) constructing a stream-tube mapping between (i) regions (; FIG. A) of a cross-section of a conduit () that supplies molten glass () to the forming apparatus () and (ii) regions (; FIG. B) on the exterior surface of the forming apparatus (); (B) using the stream-tube mapping to select a temperature distribution for the cross-section that results in a desired mass, thickness, and/or temperature distribution of molten glass () on the surface of the forming apparatus (); and (C) heating and/or insulating the conduit () so as to produce a temperature distribution for the cross-section which equals or at least approximates the distribution selected in step (B).

US Patent:

20080202165, Aug 28, 2008
Filed:

Feb 8, 2008
Appl. No.:

12/069333
Inventors:

Steven F. Hoysan - , US
Steven Michael Milillo - State College PA, US
William Robert Powell - Horseheads NY, US
International Classification:

C03B 17/06
US Classification:

65 90
Abstract:

Methods for reducing stress on an isopipe during manufacture of a drawn glass sheet are disclosed including a method comprising providing an isopipe having a root, heating the isopipe to a predetermined temperature, maintaining the isopipe at the predetermined temperature for a period of time sufficient to relieve at least a portion of a tensile stress on the isopipe root, coupling the isopipe to a down-corner, and then providing glass to the isopipe. Also disclosed is a method comprising heating an isopipe such that the temperature difference between the weir and the root of the isopipe, after heating and prior to coupling, is less than about 100 C. A method comprising application of a compressive force to the ends of an isopipe root during heating is also disclosed.

US Patent:

20120103019, May 3, 2012
Filed:

Oct 24, 2011
Appl. No.:

13/279847
Inventors:

Steven Michael Milillo - State College PA, US
Randy Lee Rhoads - Horseheads NY, US
International Classification:

C03B 17/06
US Classification:

65 53, 65195
Abstract:

An apparatus for making a glass sheet using overflow fusion down-draw process comprising an inlet assembly having an elliptic cylindrical section coupled to a transition section which is, in turn, coupled to an open end of an open channel of an isopipe, and an overflow fusion down-draw process for making glass sheet. The glass melt flow has a high surface velocity profile conducive to the formation of a glass ribbon over the surface of the weirs and the wedge side surfaces with the desired mass distribution.

US Patent:

20120180528, Jul 19, 2012
Filed:

Jul 11, 2011
Appl. No.:

13/180052
Inventors:

Thomas D. Ketcham - Horseheads NY, US
Joseph J. McIntosh - Painted Post NY, US
Steven M. Milillo - State College PA, US
Eunyoung Park - Elmira NY, US
International Classification:

C03B 17/06

B24B 1/00
US Classification:

65 53, 6537413, 428220, 451 41, 501127, 501 32
Abstract:

Isopipes () for making a glass or a glass-ceramic using a fusion process are provided. The isopipes are made from an alumina material which has a higher static fatigue than existing alumina materials intended for use as isopipes. In particular, the alumina materials have times-to-failure (static fatigues) of greater than one hour at 1200 C. at an applied stress of 10,000 psi. These high levels of static fatigue allow alumina isopipes to replace zircon isopipes in the manufacture of high performance glass sheets by the fusion process, including glass sheets which are incompatible with zircon isopipes but compatible with alumina isopipes, e.g., chip and scratch resistant glass sheets which have high alkali contents.

Each weir has a reinforcing portion extending upward from the base towards the tops of the weirs. A width of the base of the trough at a may be less than a top width of the trough. One or more of the top width, width of the base, or angle between an inner surface of the first or second weir and a vertical plane may be constant along a trough length of the trough.

US Patent:

20180370836, Dec 27, 2018
Filed:

Nov 18, 2016
Appl. No.:

15/776512
Inventors:

- CORNING NY, US
Robert Delia - Horseheads NY, US
Bulent Kocatulum - Horseheads NY, US
Shawn Rachelle Markham - Harrodsburg KY, US
Steven Michael Milillo - State College PA, US
International Classification:

C03B 17/06
Abstract:

Glass manufacturing apparatuses with cooling devices and methods for using the same are disclosed. In one embodiment, an apparatus for forming a glass web from molten glass includes an enclosure and pulling rolls that cooperate to draw a glass web in a draw direction rotatably positioned in an interior of the enclosure. A cooling device for extracting heat from the glass web is in fluid communication with a cooling fluid source and includes an actively cooled flapper disposed in the interior of the enclosure that is movable to facilitate varying the heat extraction. The actively cooled flapper serves as a heat sink in the interior of the enclosure and the cooling fluid extracts heat from the actively cooled flapper to remove heat from the glass web and the enclosure.

International Classification:

C03B 17/06
Abstract:

A system includes an overflow distributor and a support member. The overflow distributor includes a first sidewall, a second sidewall opposite the first sidewall, and a floor extending between the opposing first and second sidewalls. Interior surfaces of the first sidewall, the second sidewall, and the floor cooperatively define a trough configured to receive molten glass. Exterior surfaces of the first sidewall and the second sidewall are configured to direct molten glass that overflows the trough. The support member is disposed between the opposing first and second sidewalls of the overflow distributor and abutting an exterior surface of the floor of the overflow distributor.
