Abstract: Methods of finishing an edge of a glass sheet comprise the step of machining the edge of the glass sheet into a predetermined cross-sectional profile along a plane taken transverse to the edge of the glass sheet with an initial average edge strength ESi. The methods also include the step of finishing the edge with at least one finishing member, such as an endless belt, without substantially changing a shape of the predetermined cross-sectional profile. In one example, a wet slurry including an abrasive can be applied to at least one of a finishing member and the edge of the glass sheet. After finishing the edge, example finished average edge strengths ESf can be at least about 250 MPa. In addition or alternatively, in another example, the ratio ESf/ESi can be within a range of from about 1.6 to about 5.6.

Abstract: The present invention is directed to a substrate product for use in the manufacture of active matrix liquid crystal display panels. The product includes a display substrate suitable for use as a display panel. The display substrate has a thickness less than or equal to 0.4 mm, a composition that is substantially alkali free, and a surface smoothness that allows the direct formation of thin-film transistors thereon without a prior processing step of polishing and/or grinding. The product also includes at least one support substrate removably attached to the display substrate.

Abstract: Described herein are methods for protecting glass.

Abstract: Described herein are methods for protecting glass. The methods include applying to at least one surface of the glass a coating composition, wherein the coating composition comprises a base soluble polymer, a volatile base, a surfactant and water. Polymer beads may be included in the coating to prevent blocking of adjacent glass articles, typically glass sheets. Advantageously, the beads may also prevent abrasion of the glass sheets.

Abstract: Packages (11) of glass substrates (13) are provided in which the surfaces of the substrates are coated with a water-removable protective coating and then sealed in an air-sealing container (19), e.g., a polymer bag or a polymer wrapping, having an internal volume which is vacuumed, filled with an inert atmosphere, or filled with humidity-controlled air prior to sealing. In this way, the substrates can be stored for at least 6 months in an ambient environment having a relative humidity of 90 percent at 50° C. without substantial degradation of the protective coating.

Abstract: A cathode ray tube with an improved tubular glass neck member having a softening point in the range of 640-650° C., an annealing temperature in the range of 460-472° C., a strain point in the range of 420-425° C., a coefficient of thermal expansion in the range of 94-97×10−7/° C., and a linear x-ray absorption value of at least 100 cm−1 and a composition, as calculated in weight % on an oxide basis, consisting essentially of 46.5-49.5% SiO2, 1.5-2% Al2O3, 0.5-1.5% Na2O, 10-12% K2O, 2-3% SrO, 1-1.8% BaO, 32-34% PbO, 1-1.5% ZnO and a fining agent.

Abstract: These color television (CTV) panel tint glasses involve using base CTV panel glass compositions with enhanced levels of Ni and Co colorants. The approach uses non-lead CTV panel glass compositions with high levels of Ni and Co oxide as colorant glasses for tinting clear CTV non-lead panel glass. Nickel oxide was varied from 2 to 18%, while cobalt oxide was varied from 0.2 to 2%. A preferred range of compositions with cobalt oxide levels below 1% and nickel oxide levels below 10% was found to be very acceptable for CTV panel colorants.
