Abstract:
Surface nucleated glass ceramics for television cover glass applications. The glass ceramic may include lithium alumina silicate compositions. The glass ceramics may be ion-exchanged or chemically strengthened.
Abstract:
A method is disclosed for plugging selected cells of a honeycomb monolith so as to form a fluidic reactor, the method comprising contacting selected cells of a honeycomb monolith with a melted or softened plug material, the material comprising at least one sinterable particulate and a binder, the binder comprising at least one thermo-setting component and at least one UV-radiation curable polymer, the contacting performed such that a portion of the material remains in contact with the selected cells and plugs the selected cells; cooling the melted or softened plug material such that the thermo-setting component sets; after cooling, irradiating the portion of the material so as to at least partially cure the radiation curable polymer; and after irradiating, debinding or debinding and sintering the portion of the material so as to remove the binder or s as to debind and sinter the at least one sinterable particulate, wherein the step of debinding or debinding and sintereing is performed with the cells of the monolith in a vertical orientation resting on a flat surface with a compatible ceramic or other refractory material felt covering the openings below and above and with a weight resting on the upper face, with optional shims defining the distance between the felt and the end faces.
Abstract:
Video display screens for "video off" illumination comprise an imaging display panel, a cover glass sheet for the display panel, and a light source for injecting light into the cover glass sheet, wherein at least a portion of the cover glass sheet is provided with at least one light-scattering bulk or surface element effective to scatter a portion of the light at an angle normal to plane of the cover glass sheet, for front surface illumination, or to scatter a portion of the light into the plane of the sheet, for sheet border or edge illumination.
