Filed:

Jan 25, 2001

Appl. No.:

09/769907

Inventors:

Suresh T. Gulati - Elmira NY
David I. Wilcox - Mansfield PA

Assignee:

Corning Incorporated - Corning NY

International Classification:

B05B 114

US Classification:

239553, 239548, 2395535, 2395533, 239552

Abstract:

A burner nozzle having a hot face, side surfaces, and a plurality of internal gas flow passages and comprising a plurality of slits oriented in at least two different directions, wherein a selected number of the slits are formed in the hot face and/or side surfaces. The optimized location and depth of the slits relieve stresses that arise from temperature differences within the burner nozzle, caused by operation in high temperature furnaces, thereby extending the life (time to failure by fracture) of the burner nozzle.

Corning Incorporated - Corning NY

International Classification:

B32B 15/00

US Classification:

428191, 428410, 428426

Abstract:

A tempered glass sheet article includes a glass sheet having a thickness t, at least one edge, and at least one surface. The at least one edge is connected to the at least one surface by an edge-to-surface corner. The edge-to-surface corner is rounded with a radius r and has a surface compression that is at least 78% of a surface compression measured at or near a center of the at least one surface.

International Classification:

C03C 15/00

Abstract:

Strengthened glass substrates and methods of reducing warp in strengthened glass substrates having 3D and 2.5D shapes are disclosed. In one embodiment, a strengthened glass-based article includes a first surface, a second surface opposite the first surface, and an edge between the first surface and the second surface. The edge is asymmetric with respect to a plane that is located at an average depth of the strengthened glass-based article and is parallel to the first surface and the second surface. The strengthened glass-based article has an expected warp Wbased at least in part on a shape of the asymmetric edge of the strengthened glass-based article. An actual warp Wof the strengthened glass-based article is less than 85% of the expected warp metric Wof the strengthened glass-based article. The actual warp Wof the strengthened glass-based article is measured with a concave surface facing up.
