Abstract: A syntactic structural foam product in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres and dry resin powder, of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. The dry resin powder in an other embodiment of the invention includes unexpanded expandable powder which will expand into microballoons in the confined spaces in which they reside and effect a bonding relation with surrounding particles upon supply of heat to the mixture.

Abstract: A mineral wool article including a mineral wool layer, at least a region of which extends from at least one surface of the mineral wool layer into the mineral wool layer to an impregnation depth t. The region of the mineral wool layer includes individual fibers and is impregnated with an impregnating substance which adheres to the fibers and encloses the fibers without sealing gaps defined between the fibers so as to permit the surface of the mineral wool layer to retain an open surface structure. The gaps between the fibers in the region include bridge formations of the impregnating substance, which bridge formations are configured to permit air to penetrate through the mineral wool layer without essentially being impeded and to trap solid particles and thereby prevent emergence of the particles from the surface of the mineral wool layer. The impregnating substance provides the article with a soft and warm touch.

Abstract: A thick column is formed by masking and etching a substrate, and the column is thinned to a very small diameter (e.g., .ltoreq.5 nm) by oxidizing the column and removing the oxide layer. A metal layer is deposited on the surface of the substrate, and the column and substrate are etched to form a pit. The backside of the substrate is etched to form an aperture surrounded by the metal layer. Alternatively, the metal layer is removed and a dopant layer is implanted into the substrate, followed by the etching of the backside, leaving an aperture surrounded by the dopant layer. In a second alternative, the oxidized column is broken from the substrate, and the backside is etched, leaving an aperture surrounded by an oxide layer. These processes can be used to fabricate apertures of very small and reproducible dimensions for such instruments as near field scanning optical microscopes and scanning ion conductance microscopes.

Abstract: An adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac consisting essentially of 35-75% by weight of novolac, less than 25% by weight of water, and 10-40% by weight of an aliphatic divalent, trivalent or tetravalent alcohol. The adhesive composition may also contain up to 20% by weight of filler, based on the amount of novolac, water and alcohol. In a method for preparing the adhesive composition based on resorcinol novolac or resorcinol-phenolic novolac, the novolac is produced by conventional condensation, whereupon an aliphatic divalent, trivalent or tetravalent alcohol is added and water in the novolac is distilled off, resulting in an adhesive composition as defined above. Alternatively, the amount of water can be reduced in the condensation of the novolac to be replaced with an aliphatic divalent, trivalant or tetravalent alcohol.
