Abstract: An improved method for the fabrication of a reinforced composite. The method includes assembling rigid rods into a geometric structure such that all interstitial voids are interconnected, infiltrating the geometric structure with particles, impregnating the infiltrated geometric structure with an appropriate liquid matrix binder or precursor, and treating the impregnated geometric structure such that the binder solidifies to form the reinforced composite.

Abstract: Sintered glass pellets which generally decrease in particle size as they increase in specific gravity provide a unique filter medium which varies from larger pellets at its inlet (upstream) upper portion to smaller pellets at its outlet (downstream) lower portion. In view of the variation in specific gravity, particles forming the filter medium generally resume substantially their initial respective positions after the medium is back-flushed for cleaning. Although pellets throughout the medium differ in specific gravity, they are made of the same ingredients. The individual pellets are formed by granulating finely-ground glass with a suitable binder and sintering the resulting granules.

Abstract: A natural stone panel is constructed from rectangular sheets, slabs or blocks of natural stone, particularly marble or onyx and constructed by placing an array of rectangular stone blocks on a work surface, placing a fiberglass backing on the upper surface of the array, applying an adhesive, which can have a stone dust filler, to the joints between adjacent blocks, on the blocks and on the fiberglass backing, which is rolled into contact with the blocks. After hardening or curing of the adhesive, the exposed stone block surfaces can be polished, an overlay of clear plastic applied to the surface of the stone blocks, and the panel edges trimmed with a suitable cutting tool. The panels formed can be wall mounted by a suitable adhesive bonding the fiberglass backing to the wall surface, or alternatively, the panels can be adhesive bonded to a floor surface.

Abstract: A photocathode for electroradiographic and electrofluoroscopic apparatus which contains a stack arrangement of perforated foils of a material with a high atomic number, in particular, double layer perforated foils with two electrically conducting outer layers and an insulating layer arranged in between which obtains relatively high sensitivity and high resolution permitting its use in medical diagnostic apparatus is described along with method of manufacturing the photocathode.

Abstract: A method for producing a fishing rod made of a glass fiber-reinforced synthetic resin which comprises impregnating a glass cloth with a thermosetting synthetic resin to form a prepreg, wrapping the prepreg about a tapered mandrel, curing it under heat, and then pulling out the mandrel, wherein the glass cloth has letters, geometrical figures or other decorative designs applied to the whole or a part of its surface by printing or coating, and the thermosetting synthetic resin is the one which can give a transparent cured product.

Abstract: Texturing the surface wood comprising moving randomly positioned, rigidly mounted shredding points along the surface of the wood, orienting the direction of movement of the shredding points generally in the direction of the grain but slightly at variance with the grain, bearing down to engage the shredding points into the grain of the wood, ripping and shredding fragments of the grain as the shredding points cross the grain in the direction slightly at variance with the grain while leaving the shredded fragments still attached to the wood surface at one end, lifting and randomly orienting the shredded fragments of grain still attached to the wood surface as the shredding points move along the surface thereby imparting a rough appearance of randomly oriented grain fragment separations covering the surface.

Abstract: Cork-resin ablative insulation material is prepared in a form suitable for application to complex curved surfaces by mixing finely divided cork with a B-stage curable thermosetting resin, forming the resulting mixture into a block, B-stage curing the resin-containing block and slicing the block into sheets. The B-stage cured sheet is shaped to conform to the surface being insulated, and further curing is then performed. Curing of the resin only to B-stage before shaping enables application of sheet material to complex curved surfaces and avoids limitations and disadvantages presented in handling of fully cured sheet material.

Abstract: Printed wood paneling having a reduced flame spread rating is provided by embossing the wood surface to be finished to depress in a relatively uniform pattern of depressed portions at least about 20% up to about 70% of the surface area of the wood to a depth of at least about 0.01 inch, and these depressed portions are then filled with an intumescent fire retardant filler and the excess filler is substantially removed from the undepressed portions of the wood surface. The embossed panel with the depressed portions thereof filled with intumescent fire retardant filler is then finished in conventional fashion by applying a filler, sanding, base coating, printing, and usually embossing. A clear topcoat is then applied to protect the finish.

Abstract: A process for making a microscope side having a specimen hermetically sealed on a transparent slide plate by a transparent coating of a plastic material in solid form. Preferably, the plastic material is applied to a slide plate with a specimen thereon in liquid form and converted to a solid coating of transparent plastic material.

Abstract: A multilayer steel-reinforced concrete panel assembly comprises a steel-reinforced concrete outer plate, a steel-reinforced concrete inner plate and a layer of insulation sandwiched between these plates. The outer plate and the inner plate are interconnected by flat anchors traversing the intermediate insulation layer and the anchors are distributed along an imaginary circle whose diameter is greater than the length of the small side of the rectangular panels. At least three such flat anchors are provided, two of which are capable of absorbing all of the stresses while all of the flat anchors are disposed symmetrically with respect to the longitudinal plan axis of the panel. The flat anchors take up all of the stresses to which the panel may be subject and thus eliminate the need for an additional anchor at the centroid of the panel, i.e. the center of stress forces and the like.

Abstract: An epoxy adhesive sealant composition comprised of an uncured epoxy resin composition and a composition capable of curing the epoxy resin composition, one of said compositions containing a coloring agent effective to impart latently transient color to said composition unlike the color of the non-colored composition. Substantially equal amounts of each of said compositions are combined to form a substantially uniformly colored composition which becomes essentially colorless with curing of the epoxy resin composition.

Conductive strips are sewn or otherwise secured to the edges of the glass fiber mat and the protecting layers can either be flexible plastic material or alternatively can be rigid panels such as plywood, plasterboard or the like.
