Abstract: A technique for the manufacture of synthetic sheet material having a textured surface and suited for use as floor or wall covering. The technique in accordance with the invention includes the printing of a decoration on a support member and the applying of a transparent plastisol in the form of a discontinuous layer over and in accordance with the decoration. The invention also contemplates the application of a continuous wear layer which, in the final product, will either be disposed between the discontinuous transparent plastisol and the decoration or will cover the discontinuously applied plastisol which provides the textured effect.

Abstract: A colorless liquid ink is provided which yields a distinctive marking color on exposure to normal environmental conditions of temperature and pressure as when used for writing on a sheet of plain paper. This ink may be encapsulated to give pressure-rupturable microcapsules. Autogenous, pressure-sensitive record materials are provided by incorporation of such microcapsules in or on sheets of paper for use singly or in manifold duplicating systems which respond to printing-pressures applied by un-inked printing members.

Abstract: This invention relates to a metal plated polymeric article, and method for the preparation thereof. The polymeric material used to form the article comprises a polyblend of a styrene polymer blended with a grafted chloroprene rubber and an inorganic compound. The grafted chloroprene provides the styrene polymer with high impact strength and serves as a source of labile halogen for flame retardancy. The inorganic compound catalyzes the evolution of halogen providing fire retardant properties to the metal plated polymeric polyblend article.

Abstract: A cooking utensil formed from a high temperature aluminum base alloy component exhibiting favorable formability, said aluminum base alloy component comprising from about 0.1-0.7% zirconium, 0.1-0.4% chromium, 0.3-1.5% manganese, and the balance essentially aluminum and having at least a first and a second major surface, said second major surface being in opposing relationship to said first major surface; a glass or ceramic first covering from about 40 to 100% of the surface area of said first major surface, said glass or ceramic being bonded to said aluminum base alloy component; and a heat resistant organic resin coating over said glass or ceramic component and said first major surface of said aluminum base alloy component.

Abstract: An insulating material primarily for use on the interior of buildings and formed of a blanket of felted fibers (such as glass fibers) of relatively high density having an impervious flexible facing on one side for appearance and for defining a vapor barrier. The facing including a narrow edge strip extending beyond a margin of the fibers for defining a tab for overlapping and sealing a joint with an adjacent blanket. The marginal tab is protected during handling, shipping and installation by a disposable strip of insulation partially severed from the main body of the material but temporarily remaining in original position.

Abstract: In accordance with the invention, hollow pellets having outer surfaces of one material and inner surfaces of another material are manufactured by dropping drops of liquid into a bed of powder containing the material of which it is desired to make the outer surface portions of the hollow pellets and preferably also a binder, the liquid containing the material of which it is desired to make the inner surface portions of the hollow pellets. When the drops of liquid fall into the powder, the powder immediately forms a spherical shell around each drop so as to form the hollow pellets upon vaporization of the liquid. It is preferred that the powder additionally contain some sodium bicarbonate or the like and that the liquid be an aqueous acid solution such that, upon initial formation of the spherical shell of powder, the acid reacts with the sodium bicarbonate to generate carbon dioxide which causes the spherical shell to expand while yet additional powder coalesces onto the shell.

Abstract: An apparatus and method of using same to form tubular tapered shafts particularly adapted for golf clubs, ski poles, fishing rods and the like. The material used in forming the shafts is a thermo-setting resin sheet that has a number of elongate, laterally spaced, parallel fibers of graphite carbon, boron or like material therein, which fibers have a tensile strength comparable to steel, but are only a fraction of the weight of the latter. The apparatus and method of using the same is characterized by the tubular shaft being formed with exterior and interior cylindrical wall surfaces that are truly concentric, and with the fibers embedded in the polymerized resin being pre-tensioned and spaced from one another.

Abstract: A laminated molded insulation material for insulation of electrical machines and particularly useful for conductor slot insulation of dynamo-electric machines is produced by covering both sides of a dielectrically strong, homogeneous electrically insulating polyheterocylene foil such as polyhydantoin with protective layers of tangled fibers such as an aromatic polyamide paper known under the trade name "Nomex". The composite consisting of the protective tangled fiber layers joined to the insulating foil is then enclosed on both sides by layers of a high-tensile strength, fiber-reinforced synthetic resin using, for example, a glass fleece or glass-silk fabric as the fiber material, and which are joined to the protective tangled fiber layers and in such manner that within the protective layers opposite the insulating foil there exists a continuous remainder of non-resin impregnated tangled-fiber structure consisting solely of tangled fibers.

Abstract: An adhesive composition comprised of a nitrile rubber having carboxyl groups and a polyamide resin derived from polymeric fatty acids and alkylene polyamines. Such adhesive compositions are useful upon sheet members of plasticized polyvinylchloride, among other possible uses.

Abstract: A laminated optical element is produced by prepositioning a polarizing sheet, which has been coated on both sides with adhesive compatible with the encasing material, in a mold so as to accurately space the polarizing sheet from the inner mold surfaces, injecting a monomer of allyl diglycol carbonate into the mold so as to completely encase the polarizing sheet, and then curing the laminate. The process includes producing stress free castings capable of being subjected to subsequent color accepting treatment and various finishing processes. The laminated product provides a fully encased polarizing sheet with a thin layer of uniform thickness of the polymer on the front side of the polarizing sheet which may be readily finished for optical devices.

A quantity of foamed plastic fills the cells and is bonded to the walls thereof. A structural skin lies across at least one face of the core and is bonded to the open ends of the component cells, thereby rigidifying the product.

Abstract: A wall structure characterized by inner and outer wall coverings and positioned therebetween at least one protective inner layer defined by a rib-like formation defining a series of pocket-like spaces between said wall coverings, which spaces embody a protective medium forming with the rib-like formation and said wall coverings a wall structure which is highly resistant to impact, fragmentation or severe damage by piercing. The rib-like formation is of a material selected from the group consisting of precipitation hardening stainless steels, mar-aging nickel steels, alloy steels and titanium alloys and having a yield strength of at least about 200 ksi. The protective medium may include a fire quenching material.
