Abstract: A handle substrate of a composite substrate for a semiconductor is provided. The handle substrate is composed of polycrystalline alumina. The handle substrate includes an outer peripheral edge part with an average grain size of 20 to 55 ?m and a central part with an average grain size of 10 to 50 ?m. The average grain size of the outer peripheral edge part is 1.1 times or more and 3.0 times or less of that of the central part of the handle substrate.
Abstract: A fibrous structure including filaments wherein the filaments comprise one or more filament-forming materials and one or more active agents that are releasable from the filament when exposed to conditions of intended use, the fibrous structure further having at least three regions. Methods of treating fabrics with a fibrous structure are also provided herein.

Abstract: A wall insulation system includes a thermoplastic polymer foam board, ribs of melt barrier material extending horizontally across the width of the thermoplastic polymer foam board and a metallic facing bonded to the outside surface of the thermoplastic polymer foam board and covering the outside primary surface of the thermoplastic polymer foam board and any ribs exposed along the outside primary surface of the thermoplastic polymer foam board. A rib of melt barrier material extends across the width of the thermoplastic polymer foam board in any 50 centimeter distance along the height of the foam board.
Abstract: Nonwoven double layer industrial textiles comprising a plurality of interconnected selectively slit and profiled folded panels formed from suitable sheet or film materials. Each panel includes two fold regions having an array of slots and seaming loops. The folded panel is formed by folding each fold region toward the panel body, thereby providing seam loops and seam loop receiving openings, which are used to connect adjacent folded panels in a given layer of the textile. Two such layers are bonded together in overlapping relation such that outside free edges of any of the fold regions are returned and sealed interior to the double layer. Further panels composed of heat or wear resistant material can be connected to lateral outside edges of panels forming the textile.
Abstract: Non-woven double layer industrial textiles comprising a plurality of interconnected selectively slit and profiled panels formed from suitable sheet or film materials. Each panel includes two fold regions at each end. Each fold region has an array of slots and strips which form hem loops and hem loop-receiving openings by folding each region beneath and toward the panel body. The panel further includes two seam regions at a central portion of the panel, which when folded, provide seam loops and seam loop receiving openings. Outside free edges of the end fold regions are returned and sealed interior to the double layer so as to avoid fraying of free ends. Each seam region of the folded panel is interconnectable with the corresponding seam region of adjacent similar folded panels by means of a seam connecting member. Additional panels composed of heat- or wear-resistant material can be connected to lateral outside edges of panels forming the textile.
Abstract: A method for reworking a ceramic structure. A portion of a first facesheet is removed from the ceramic structure to form a first aperture. The first facesheet comprises a number of layers of a first ceramic material. A portion of an inner section of the ceramic structure is removed to form a second aperture. The second aperture extends from the first aperture into the inner section. The inner section comprises a second ceramic material bonded to the first facesheet and has a lower density than the first facesheet. A ceramic replacement material is placed in the second aperture. A number of replacement ceramic layers are placed in the first aperture. Ceramic particles are placed between the first facesheet and the number of replacement ceramic layers. The ceramic particles are sintered to bond the number of replacement ceramic layers to the first facesheet.

Abstract: An industrial mat that has a core construction that provides strength and rigidity to the mat, with the core construction being formed of a support structure that includes one or more elongated components or a plurality of elongated members of wood, engineered wood, a thermosetting plastic material or a metal. The mat includes an encapsulation of a durable skin that includes crumb rubber particles embedded in a polyurethane matrix that surrounds and encapsulates the entire core construction. The skin has a thickness sufficient to provide environmental resistance to the core construction to which it is applied while also providing abrasion resistance to the mat.
