Abstract: There is disclosed a cloth-like tape substrate. The substrate is made from an essentially unbonded cellulose web having a breaking length between about 0.71 km and 2.66 km which is saturated with a soft rubber-like polymer, coated with a low stiffness polymer, and then embossed. The unbonded web is formed from at least 25% by weight of pulp having R.sub.10 values greater than 94%. The soft rubber-like polymer has a glass-transition temperature between -50.degree. C. and 0.degree. C. and the low stiffness polymer coating has a tensile modulus less than 1,000 MPa.

Abstract: A process for making a fabric is used to produce bedding especially well suited for hospitals, nursing homes, jails, mental institutions, and the like. The process begins with a tightly woven taffeta or ripstop weave cloth made from fine nylon or polyester threads. First, one surface of the taffeta is coated with a urethane water repellent. Next, the partially finished product is treated by immersion in a bacteriostatic and fungistatic, a fire retardant, and an anti-static bath. The cloth is then cut and sewn into a desired, at least partially, finished product, such as a pillow cover or mattress ticking and can be vented as desired.

Abstract: Coating composition for protecting bodies immersed in sea water, comprising(a): a sub-layer of chlorinated natural rubber, and(b): an external layer comprising a polymer with amide groups.An intermediate layer can be provided, said layer consisting of a modified chlorinated natural rubber.

Abstract: An adhesion-promoting primer, e.g., an emulsion polymer, is employed to bond organic elastomers to silicone elastomer adhesives. A multiple glazed unit having an organic elastomer sealant about its periphery is mounted into a curtainwall system by first coating the exposed organic elastomer sealant with a suitable primer before bonding the multiple glazed unit to the curtainwall system with silicone elastomer adhesive.

Abstract: This invention relates to an improved intravaginal ring for use as a contraceptive comprising an inert elastomer core, a medicated layer encircling the core and an outer inert elastomer layer and method of manufacturing the intravaginal ring.

Abstract: Brass-coated steel cord is provided with improved adhesive characteristics for use in tire making, by coating it with certain combinations of sulfur-containing accelerators and phosphate corrosion inhibitors.

Abstract: A method for coating or lining metal surfaces, such as car or truck bodies, by applying plural layers of a pre-mixed, defined rubber composition and allowing the rubber coating to cure in situ.

Abstract: A method for protecting the surface of a metal surface which comprises applying to said surface an organophosphorus compound of the formula ##STR1## wherein A IS 0 OR 1R is a branched or unbranched chained bivalent alkylene radical of 1 to 12 carbon atoms which is substituted or unsubstituted and can contain in the chain structure --O--, --S--, ##STR2## R' is a branched or unbranched alkyl radical of 1 to 12 carbon atoms which can be halogen substituted and can contain in the chain structure ##STR3## X is an epoxy ring, halogen, alkylene, carboxylic acid ester residue, amino, isocyanato, isothiocyanato, urea, thiourea, urethano, alkyl substituted thio radical or the radical or a heterocyclic ring containing O, S, or N in the ring structure; a new organophosphorus compounds having the formula set forth above and more particularly defined by specific chemical structures.

Abstract: A method for repairing a roof comprising the steps of: spreading a porous conformable membrane over the existing roofing materials, moistening the membrane to cause it to conform to the roofing surface, tacking the membrane through the existing roofing materials and into the roofing substrate, applying a sealing adhesive to the membrane, and covering the membrane with a waterproof roof coating.

Abstract: An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer and a water soluble, heat reactable o-cresol-formaldehyde-resorcinol resin, in certain amounts, is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.

Abstract: A composite of a metallic material and vulcanized rubber is produced by contacting an unvulcanized rubber with a metallic material coated with a ternary alloy composed of copper, zinc and tin.

Abstract: Unsaturate-resorcinol polymers comprising alkylene-bridged resorcinol units resulting from introducing olefinic unsaturated radicals of 3-10 carbon atoms into the nucleus of the resorcinol are condensed with resol which condensation products are adhesives for bonding textiles material to rubber.

Abstract: An improved polyethylene terephthalate tire yarn is prepared by applying to the yarn a finish composition comprising a polyalkylene glycol compound having the formulaR--(O--R.sub.1 --O--R.sub.2).sub.n --OHin which R.sub.1 and R.sub.2 are the same or different lower alkylene units such as ethylene, propylene and so forth up to 5 carbon atoms, R is an alkyl group containing 1 to 8 carbon atoms, and n has a value to produce a molecular weight of at least about 300; and about 5 to 35 parts per 100 parts, by weight, of said polyalkylene glycol compound of a triol compound having the formula: ##EQU1## WHEREIN R and R' are independently at each occurrence hydrogen, methyl or ethyl and r, s, and t are integers from 1 to about 20. This method of finishing the tire yarn results in an improved adhesion of the fiber to rubber.

Abstract: A novel self-adhesive type multi-layer laminated bituminous roofing membrane suitable for the formation of the roofing or waterproofing layer on roofs, floors and the like is provided. It comprises a base sheet of a sheet-like material, one or more bitumen layers coated on all or part of one or both faces of the base sheet, at least one layer of compound bitumen including both bitumen and rubber and/or resin laminated on all or part of the surface of said bitumen-coated layer on the base sheet and at least one release sheet laid over the whole surface of said compound bitumen layer.This roofing membrane is produced by uniting the bitumen-coated base sheet and the compound bitumen-coated release sheet, and can be applied over a substrate in a simple manner, without the step of melting or liquefying bitumen as in the conventional application process.

Abstract: Rubber is adhered to metal such as the metal in the belt of a vehicle tire or conveyor belt, by first coating the metal with rubber containing a small amount of the amine of cobaltous chloride, CoCl.sub.2.2NH.sub.3. The metal may first be zinc coated.

Abstract: Method for bonding a room temperature vulcanisable silicone rubber to a porous substrate of masonry or wood. The method involves applying to the porous substrate a primer composition comprising a cyclised rubber resin, an organic solvent and a film-forming polyester resin in a proportion of from 0 to 40% by weight based on the weight of cyclised rubber resin. The primed surface is dried and a room temperature vulcanisable silicone rubber composition of specified type then applied.
