Abstract: Windows for vehicles particularly windscreens comprise sheets of glass adhesively bonded together by means of a hot melt adhesive which is an ethylene copolymer containing from 7 to 18% by weight of methacrylic acid and sufficient methyl methacrylate such that together the methyl methacrylate and methacrylic acid constitute from 20 to 35% by weight of the copolymer and the copolymer has a melt flow index of at least 0.1 and not more than 2. Also disclosed are ethylene copolymers as defined above.

Abstract: This invention relates to composite articles of manufacture and to a method for the preparation of these articles. The articles are impact-resistant, three-dimensional and rigid. The articles are comprised of two essential elements: (1) A pliable, hollow premolded outer plastics layer and (2) an essentially rigid non-cellular organic plastics structural backing member solidified in the hollow interior of the plastics skin, and essentially solidly filling said hollow interior. The hollow outer layer is prepared in a manner to have an access opening to its hollow interior. A liquid plastics composition is next prepared in a separate step that comprises an organic binder which solidifies at room temperature, in most cases by converting to a thermoset stage. This liquid composition is then introduced through the access opening into the cavity of the premolded outer layer.

Abstract: An article capable of being hot stamped with desired lettering or designs comprising a plastic laminate and an overlying carrier film with colored matter attached to an appendage portion of the plastic laminate. The back of the laminate has a pressure-sensitive adhesive protected by a removable covering or backing. The method of imprinting and using the article comprises hot stamping the foil and underlying plastic laminate to form the desired lettering or design, removing the foil and appendage portion from the plastic laminate, removing the protective backing to expose the adhesive and to affix the imprinted laminate to a plaque or other item. The process of imprinting on the article includes hot stamping the laminate to deboss it and transfer the coloring matter to the debossed portions, and removing the carrier film.

Abstract: A water dispersible nonwoven fabric comprising one or more layers of overlapping, intersecting fibers and from about 4 percent to about 35 percent by weight of a binder comprising an alkali salt of a sulfated cellulose ester, said nonwoven fabric having good tensile strength and abrasion resistance in the presence of body fluids such as urine, blood, and menstrual fluid. The nonwoven fabrics may be incorporated in body fluid absorbent products such as sanitary napkins, diapers, surgical dressings, tampons, nursing pads and the like.

Abstract: Combination of a polyolefin; a crosslinking agent; a halogenated phosphorous-nitrogen compound having the formula ##EQU1## where R' is selected from the group consisting of hydrogen and alkyl radicals having 1 to 3 carbon atoms, R is a cyano alkyl radical having 2 to 6 carbon atoms and X is chlorine, bromine, or iodine; ammonium polyphosphate; and hexachlorocyclopentadiene dimer yields a composition which is strong, fire-retardant and also strongly adherent to certain surfaces including aluminum.

Abstract: La.sub.2 O.sub.2 S particles are employed as carrier hosts in a cathodo-luminescent penetration phosphor composition for cathode ray display tubes. Tb and Eu ions are used in low concentrations as activators in the control of the red and green optical emission from within a film of the activated host material.

Abstract: The adhesive properties of compositions which contain an organic isocyanate, with or without a film-former, are improved by the inclusion of (a) an aliphatic hydrocarbyl nitrite or (b) a nitrite ester of a carbamic acid which acts as an adhesive promoter. The compositions are useful for adhering natural and synthetic polymeric elastomers, and are particularly useful in the production of laminations formed from polyurethane polymers and other substrates including metals, etc. and especially the formation of laminations from the cured tread of a conventional rubber to a curable polyurethane prepolymer composition which can be formed in the shape of a tire body.

Abstract: The adhesive properties of compositions which contain an organic isocyanate, with or without a film-former, are improved by the inclusion of nitrosyl halide adducts of unsaturated compounds which act as adhesive promoters. The compositions are useful for adhering natural and synthetic polymeric elastomers, and are particularly useful in the production of laminations formed from polyurethane polymers and other substrates including metals, etc. and especially the formation of laminations from the cured tread of a conventional rubber to a curable polyurethane prepolymer composition which can be formed in the shape of a tire body.

Abstract: An adhesive tape that tenaciously adheres to the surface of films, paper, wood, plastic, metal, stone and the like, by simply pressing it thereon, and that can easily be removed with water or aqueous alkaline solutions, comprises a support and an adhesive layer consisting of a homogeneous mixture of at least one water-soluble and/or alkali-soluble polymer and of a tackifier consisting of a carboxylated monoether of a polyglycol.

Abstract: A decorative covering material and a process for applying said covering material to vehicle panels such as the roof panel of automobiles to enhance the exterior appearance thereof. The decorative covering material comprises a heat-softenable plastic sheet incorporating a coating of a heat-activatable adhesive over substantially the entire undersurface thereof and which sheet is pretrimmed to a preselected shape and size, and incorporates fastening strips along at least a portion of the terminal edges thereof for securing the decorative material over the panel to prevent movement thereof relative to the panel surface. The decorative covering material is further characterized as embodying, in the inner central area thereof, a contour and wherein the plastic material incorporates a residual memory whereupon a shrinkage of the covering materials occurs during a heating thereof to form a smooth and taut covering layer over the exterior surface of a panel to which it is applied.

Abstract: A multiple glazed glass article including two glass panels separated by a spacer and held in a marginal frame is disclosed. Two coatings are present on one of the glass panels providing the article with useful and esthetic reflective and transmission properties. One coating preferably includes a metal such as silver, chromium, iron, cobalt or nickel and the other coating preferably includes a metal oxide such as iron oxide or copper oxide. The metal oxide layer is essentially the oxide of a metal other than the metal of the metal layer.

Abstract: A strengthened glass-ceramic laminated article having a compressively-stressed surface layer substantially enveloping a tensilely-stressed core portion, produced by choosing the core and surface layer compositions such that the core undergoes a net positive differential densification with respect to the surface layer as the result of phase transformations occurring in the laminated article during crystallization in situ. Such an article offers significant advantages over glass and glass-ceramic articles strengthened by prior art methods, including improved mechanical stability, thermal shock resistance, and, most importantly, excellent high temperature strength retention.
