Abstract: A method for preparing a coated abrasive article wherein the a plurality of abrasive grains are applied to a make coat such that the abrasive grains are substantially a mono-layer. The make coat precursor is a pressure-sensitive adhesive-like or pressure-sensitive adhesive. The make coat precursor is partially cured to approximate a pressure-sensitive adhesive-like layer or when fully cured is a pressure-sensitive adhesive. The make coat precursor has sufficient "tack" to hold the abrasive grains during the application and curing of the size coat, resulting in a substantially monolayer of abrasive grains.

Abstract: Manifolds of a solid oxide fuel cell are integrally formed with the fuel cell's core. The fuel cell includes repetitively stacked anode, electrolyte, cathode interconnect gasket elements. The gasket elements space apart the interconnect and electrolyte elements and bound the anode and cathode elements. The interconnect, electrolyte, and gasket elements are provided with cutouts that define manifold passageways for the fuel and oxidant. The gasket elements further prevent the fuel from contacting the cathode elements and the oxidant from contacting the anode elements.

Abstract: A process using predetermined magnetic lines of flux to position, orient, and retain abrasive particles having a magnetic conductive coating thereon to a substrate surface for bonding to the surface by suitable electro-plating or other plating processes. The process allows use of high aspect ratio abrasive particles to produce desirable cutting, grinding, and sanding characteristics in a wide variety of tools such as saws, knives, abrasive drums, lapidary disks, and sandpaper, which are also part of the invention. Since the positioning of the abrasive particles can be controlled, various desirable patterns thereof can be produced on substrates of various shapes and sizes especially when the substrate is non-magnetic.

Abstract: Abrasive products comprising abrasive grains bonded together or bonded to a backing by means of a binder compressing an oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit. The oligomeric aminoplast resins polymerize via free radical polymerization at the site of the .alpha.,.beta.-unsaturation. Polymerization is initiated by a source of free radicals. The source of free radicals can be generated by electron beam radiation or by an appropriate curing agent or initiator upon exposure to heat or radiation energy. The coated abrasive of this invention demonstrates improved grinding performance under severe conditions as compared with coated abrasives comprising radiation curable resins heretofore known.
