Abstract: Abstract This invention provides a process for the production of surface covering materials having a textured effect which comprises (a) applying a layer of a first foamable resinous composition on to a substrate; (b) applying a second foamable resinous composition on to selected areas of the surface of the said first foamable resinous composition; (c) applying at least one essentially non-foaming layer over the said first and second foamable resinous compositions; and (d) heating to effect foaming of the first and second foamable resinous compositions whereby a surface covering material having a textured effect is produced; the said first and second foamable resinous compositions being selected whereby upon heating substantial foaming of the said second foamable resinous compositions occurs before any substantial foaming of the said first foamable resinous composition.   The invention further provides a surface covering material having a textured effect which comprises a substrate or backing layer, a layer of a first foamed resinous composition on the substrate or backing layer, a second foamed resinous composition on selected areas of the said first foamed resinous composition and a layer of an essentially non-foamed resinous composition over the said first and second foamed resinous compositions; the surface of the said material being at a higher level in areas with both first and second foamed resinous composition applied than in other areas of the surface covering material; and the said second foamed resinous composition having a structure characteristic of a resinous composition which has foamed to a significant extent whilst supported by a non-foaming substrate.

Abstract: METHOD FOR HYDRATING SILICATE GLASSES   Abstract of the Disclosure The present invention is concerned with a single-step process for hydrating alkali metal-containing silicate glasses starting with such fine-dimensioned forms as powders, granules, flakes, fibers, and thin sheets.  The process permits the precise control of the quantity of water taken into the glass structure and, where the water content in the glass is held within about 1-25% by weight, the hydrated product of the above-cited powders, gran-ules, etc., can be thermoplastically formed into sound bulk articles.  A layer of the anhydrous powders can be applied to a substrate and then hydrated in situ to form glassy paints and coatings.

Abstract: Abstract of the Disclosure:          A continuously wound strip of toweling, either solid wound or wound about a hollow central core, forms the roll with radial end surfaces.   A pair of diametrically aligned, axial pin openings are formed in one of the roll end surfaces equally radially spaced from the central longitudinal axis with radially inner extremities radially outwardly of any roll core.   If the roll is solid wound, a central axial opening is formed in the other roll end surface preferably semi-spherical in shape or if the roll is hollow core wound, the core forms the central axial opening at the other roll end surface.  In either case, with dispenser pin support and central support at the opposite e roll ends, dispensing unwinding of the strip of toweling to the pin hole radially inner extremities releases the roll for endwise pivoting about the other roll end automatically dismounting the same.   In addition to the central opening at the other roll end surface, a circumferential groove may be formed therein radially outwardly of the central opening to adapt the roll for versatile use with known dispenser dismounting structures.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention involves a method for the hoe isostatic compaction of particulate material into an article of intricate configuration.  It comprises providing a removable pattern in the appropriate precom-paction configuration of the article to be produced, coating the pattern with a first layer of conductive material and a second layer of metallic material, the two layers cooperating to provide a self-supporting and gas-impervious shell around the pattern and removing the pattern from the shell to provide a self-supporting and gas-impervious container having an internal configuration corresponding to the precompaction shape of the article to be produced.  The container is then filled with particulate material, evacuated ant sealed, and iso-statically compacted in a pressure vessel at elevated temperature until the particulate material is compacted into a dense article of complex shape. The container is thereafter removed to obtain the compacted article.          Dense articles of complex shape, such as gas turbine engine components including blades, discs and the like, are readily produced by the method of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE The invented artificial heart consists of two ventricles and two atria and is designed for inclusion in a blood circulation system via valves to operate in the same manner as a live heart.  The heart is made in the form of a rigid housing containing in its top part two inlet ports and two outlet ports. An elastic ventricle and elastic atrium constitute a symmetrical half of the heart.  The bottom part of the housing is shaped in the form of two parallel cylinders capped tightly and slidably with buckets having convex bottoms these bottoms forming pistons.  An elastic movable diaphragm is located above each piston, this diaphragm being circumferentially attached to the inside of the cylinder and to the elastic ventricle.  Physiological liquid is contained between the ventricle and the diaphragm.  The top part of the housing is connected with a branched shank designed for attaching to the human skeleton, and the buckets are attached to the branched elastic, membranaceous and pedate bearer designed to rest against respiratory muscles and their bony lining.  The volume of ventricles and of atria in the artificial heart is about four times larger in comparison with that of a live heart.  The heart is act-uated by the-motion of respiratory muscles which exert a pressure on the buckets via the bearer, the operation of the heart being similar to that of a hydraulic diaphragm-piston pump.
