Abstract: A self adhesion ensuring layer having a total thickness of 0.05 to 0.2 mm is carried on a PVC-foil carrier sheet having a thickness of 0.2 to 0.5 mm. The self adhesion ensuring layer comprises 70 to 100% by weight of synthetic caoutchouc, 0 to 16% by weight bitumin and 0 to 14% by weight talc. A ground layer may be interposed between the carrier sheet and self adhesion ensuring layer. The resultant system is useful for insulation of underground pipe.

Abstract: This invention is concerned with improving the properties of refractory supports used in the manufacture of ceramic articles such as setters, batts, saggars, cranks, stilts, thimbles, saddles and spurs, and resides in the provision on an article-supporting surface of such supports of a coating comprising comminuted plasma dissociated zircon. Also provided is a method of coating refractory supports and a coating composition comprising a dispersion of comminuted plasma dissociated zircon in a carrier liquid.

Abstract: An artificial christmas tree apparatus includes a plurality of movable branches which are closeable and openable through the relative motion of an inner and outer tube arrangement which forms the trunk mechanism of the tree. Each branch includes a decorated leafy end and an oppositely located base end which is received in the trunk mechanism. The trunk mechanism comprises an outer tube having a first and a second aperture therein and an inner tube located within said outer tube. The inner tube includes a third and fourth aperture therein. The second aperture is larger than the first aperture and the third aperture is larger than the fourth aperture. The base end of each branch passes through said second, fourth, third and first apertures respectively and is anchored by a crimp located at one end of the branch. Relative motion of the inner and outer tubes causes the branches to move from a closed to an open position and vice versa.

Abstract: A collapsible dispensing container having a laminated tubular body, the laminated tubular body including a metal foil lamination, a layer of a polyolefin on the outside of the metal foil lamination, and, on the inside of the metal foil lamination and on the outside of the polyolefin layer, a layer of a copolymer resulting from the polymerization of 100 parts by weight of (a) at least 50 percent by weight of at least one nitrile having the structure ##STR1## wherein R is hydrogen, a lower alkyl group having from 1 to 4 carbon atoms, or a halogen, and (b) up to 50 percent by weight based on the combined weight of (a) and (b) of an ester having the structure ##STR2## wherein R.sub.1 is hydrogen, an alkyl group having from 1 to 4 carbon atoms or a halogen, and R.sub.

Abstract: A tape strip is disclosed. This strip has an elongated strip portion having an outer face and an inner face with adhesive thereon. The elongated strip portion has a width not exceeding three-eighths of an inch. A pair of tape end portions are provided one at each end of the elongated strip portion. The pair of tape end portions have an outer face and an inner face with adhesive thereon. The tape end portions have a width dimension of at least one-half inch.

Abstract: A hermetic glass seal to provide the final seal for the fill ports in the glass walls of a display device such as a liquid crystal display. The seal utilizes a glass bead sandwiched between a metal cover and a polymeric separator.

Abstract: Art is stencil cast using modeling paste directly onto a substrate door, a wall section, such as, a panel, a rigid or flexible vinyl sheet or similar materials, which acts both as a base for the mold and as the substrate for permanent retention of the cast-in-place art work.

Abstract: A plurality of sound absorbing units are provided in alternate compartments of a lattice-type structure. Each of the sound absorbing units comprises four concave strip segments each extending from the midpoint of a corresponding one of the strip segments of a corresponding one of the square open compartments of the structure to the midpoint of a corresponding other of the strip segments of the corresponding one of the compartments to form a concave-sided square in the one of the compartments rotated 90.degree. relative to the one of the compartments.

Abstract: Strapping for orthodontic headgear, wrist watch straps, identificaton straps for hospital use and other uses, comprising a core constituted by a strip of substantially nonstretchable polyester film and a wrapper constituted by a composite strip comprising a layer of polyurethane film and a layer of nonwoven polyester fabric which layers have been bonded together under heat and pressure, the composite strip being wrapped around the side edges of the core with the layer of film on the outside and having its marginal edges overlapped and fused together to form a longitudinal overlap seam by a series of discrete fused stitches, and a method of making the same involving ultrasonic stitching.

Abstract: When electrically insulating ceramic substrates are coated with silicon by any of a number of methods that brings the substrate into contact with molten silicon, electrical contact can only be made conveniently to the exposed surface of the silicon coating. This invention teaches an improvement for making electrical contact to the interface surface of the silicon. It was discovered that by providing narrow slits or small holes in the ceramic substrate that upon coating the substrate with molten silicon, molten slicon will wick through the slits or holes to the uncoated surface of the ceramic.

Abstract: A disposable, absorbent pad adapted to be formed into a U-shaped configuration and to be placed at least partially about the base of a toilet to absorb moisture gravitating near such base. The pad is adjustable and can be provided with a water-proof backing as well as means for adhesively bonding the same to the floor. Several embodiment of the pad are disclosed.

Abstract: Copolyamides derived from mixed acids (a polymeric fatty acid and short-chain dibasic acid) and mixed amines (a polyoxyalkylene diamine and a short-chain diamine) are provided. These thermoplastic resin compositions are excellent reinforcing adhesives for flexible substrates and are particularly useful as box-toe construction resins.

Abstract: A synthetic resinous tube having a plurality of bonded coaxial layers with at least one layer being thermoplastic and another substantially non-thermoplastic is formed by the simultaneous coaxial extrusion of thermoplastic tubes and electron irradiation of one of the layers of the tube to convert it from a thermoplastic resin.

Abstract: A label is placed in due contact with the surface of an article being extruded and then forcibly urged to a preselected depth in the plasticized article. The label and the article are thereafter cooled.
