Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, uniformity properties and sparkle properties, as defined herein. A method of making the glass article includes, for example, slot coating a suspension of particles on at least one surface of the article to provide a particulated mask covering from about 40 to 92% of the coated surface area; contacting the at least one surface of the article having the particulated mask and an etchant to form the anti-glare surface, and optionally continuously polishing the suspension of particles just prior to slot coating. A display system that incorporates the glass article, as defined herein, is also disclosed.

Abstract: A method of forming an extrusion die comprises depositing at least one layer of a sinterable material, such as binder-free sinterable material, in a plane creating a layer of unsintered material, applying irradiation to the at least one layer of unsintered material along a pattern creating a layer of centered material, and forming the extrusion die as a single, integrally-formed piece by repeating the depositing and irradiating steps in a coordinate direction that is substantially orthogonal to the plane, wherein a new layer is superposed upon a previously sintered layer. The extrusion die formed via this method includes an inlet section having a die inlet face and a plurality of feed channels extending from the inlet face toward a honeycomb-forming section that is spaced from the inlet face and terminates in a die outlet face that includes an array of discharge channels formed from pins.

Abstract: A radial cell ceramic honeycomb structure is provided that is particularly adapted for use as a catalytic carrier or a particulate filter in an automotive or diesel exhaust system. The honeycomb structure includes a network of interconnected webs having a central axis. The network of webs includes radial webs of varying lengths, only some of which substantially extend the entire radial length of the network, and tangential webs that intersect to define rings of gas-conducting radial cells, and a rounded outer skin that surrounds the cells formed by the interconnected webs. The radial webs extending to the periphery of the network join an inner edge of the outer skin in a substantially orthogonal orientation to reduce thermally generated stresses and to increase strength of the resulting structure. The number of radial webs in the network changes along the radial length at transition zones that are defined by one of the tangential webs such that a desired cell density is achieved across the network.
