Abstract:
A high-silica glass sheet has an average thickness of less than 150 microns and an average surface roughness over one or both of its two major surfaces of less than 1 nm. The glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet may comprise a plurality of substantially parallel surface protrusions, which are visible only when a major surface of the glass sheet is viewed at an angle sufficiently removed from normal incidence.
Abstract:
Honeycomb extrudate of improved quality is extruded from plasticized ceramic-forming mixtures (30) utilizing an extruder (12) joined to a honeycomb extrusion die (14) through a connecting enclosure (16) provided with a friction-reducing inner surface, that surface (24) being effective to improve the peripheral flow of the mixture (30) to the die.
Abstract:
The application is directed to a product or material or article made of glass where the edge of the glass is protected by the application of a solid pre-formed polymer material that is contained within the thickness of the glass. The protected glass articles have a Figure of Merit in the range of 0.4 to 20, and the edge)s) of the articles have been found to withstand impact velocities of up to 500 mm/sec. The solid pre-formed polymer material that is contained within the thickness of the glass is thus applied to the edge, and it is applied such that it does not protrude into the top and bottom viewable planes, surfaces or faces (the large surface areas) of glass. The solid pre-formed polymer material, the protective material that is contained within the thickness of the glass, may be called herein a "bumper."

Abstract:
Honeycomb extrudate is made by extruding a plasticized ceramic-forming batch material to form a length of wet honeycomb extrudate, transferring the extrudate to a support tray, and transferring the tray and extrudate to a dryer, the tray being capable of contactingly supporting greater than one-third of the circumferential surface of the wet extrudate. The extrudate is subject to reduced handling damage, e.g. from forces of gravitational and/or lateral acceleration arising during transfer.
