Abstract: A pneumatic tire has a single carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the tire, and at least one insert located adjacent the carcass ply in a sidewall portion, the insert providing support for the tire load to enable the tire to operate in underinflated conditions. The carcass ply is comprised of at least one composite cord. The composite cord is formed of at least two first yarns twisted helically about at least one second yarn. The first yarns and the second yarn having different modulus of elasticity, the first yarns having a modulus greater than the modulus of the second yarn.

Abstract: The present invention relates to a pneumatic tire having a component including at least one diene based rubber and discontinuous textile cord having at least two textile yarns, wherein the cord is partially untwisted.

Abstract: The present invention provides a pneumatic tire comprising raised indicia on a sidewall of the tire, the raised indicia comprising a plurality of superposed layers of a curable elastomer composition.

Abstract: Disclosed is a tire having at least one reinforcing ply in the carcass, belt, or bead region of the tire. The reinforcing ply is comprised of a blended fiber cord. The cords, in combination with a preferred cure temperature adhesive, achieve a high degree of thermal stability allowing for the use of such cords in various reinforcing plies for a pneumatic tire and for preferred use for such cords in areas of the tire subject to high temperatures either in curing or performance.

Abstract: The invention relates to treatment of yarns for use in reinforcement of rubber products. Such treatment comprises application to the yarn of an aqueous emulsion of polyester and/or epoxy adhesive, or an aqueous alkaline dispersion of rubber latex and resorcinol-formaldehyde resin adhesive, wherein said adhesive contains a minor amount of particulate, water insoluble starch composite of starch and water insoluble plasticizer therefor. Such yarns may be in a form of a cord comprised of a plurality of yarns. The invention further relates to such treated yarns. The invention additionally relates to such treated yarns and a composite of rubber and said treated yarns. The invention additionally relates to an article of manufacture such, as for example, a rubber tire, having at least one component comprised of said composite.

Abstract: A stress sensor includes two capacitor plates held in a spaced-apart relationship by a connector block situated therebetween. The connector block includes a plurality of rods protruding from opposite connector block sides and extending into a respective capacitor plate to attach peripheral portions of each capacitor plate to the connector block. A small air gap is maintained between peripheral portions of the capacitor plates by the inclusion of a spacer member. Terminal end portions of the protruding rods are deformed such as by the application of heat over an outer surface of the capacitor plates to retain the capacitor plates in a fixed mutual relationship. The terminal end portions of the rods further serve to prevent horizontal or vertical slippage between the capacitor plates when the sensor is vulcanized into rubber compounds such as in a tire.

Abstract: The present invention is directed to a runflat tire having at least one of its components comprising the radial carcass ply, the underlay, the overlay, the bead inserts or the chippers, reinforced with polyester cords having a polyepoxide disposed on its surface. The polyester cord is formed by first obtaining a cord through twisting together a plurality of polyester yarns, secondly treating the cord with an aqueous dispersion comprising a polyepoxide, and thirdly treating the cord with an aqueous RFL dispersion comprising a resorcinol-formaldehyde resin, a styrene-butadiene copolymer latex, a vinylpyridine-styrene-butadiene terpolymer latex, and a blocked isocyanate.

Abstract: A pneumatic tire (10) comprises a radial ply (12) carcass, a tread portion disposed radially outwardly of the crown area (14) of the carcass and a crown reinforcing structure interposed between the tread portion (19) and the carcass. The crown reinforcing structure includes a belt assembly (15) having at least a first (16), radially innermost and a second (17), radially outermost belt ply as well as a textile overlay structure (18) which is superimposed radially outwardly to said belt assembly (15). The textile overlay structure is reinforced with cords (40, 51) being made of materials including nylon and aramid. At initial elongation of the cords, the primary load bearing yarns are the nylon yarns; after appreciable elongation the primary load bearing yarns are the aramid yarns.

Abstract: The present invention is directed a pneumatic agricultural or industrial tire comprising a casing and a rubber tread disposed radially outwardly of the casing, the tread having an inner tread and a plurality of tread lugs projecting radially from the inner tread, said casing having at least one component, said component comprising textile cord and a rubber composition in contact with the textile cord, the rubber composition comprising

Abstract: A pneumatic tire for heavy duty use comprises at least one radial carcass ply, a tread portion disposed radially outwardly of the crown region of the carcass plies and a crown reinforcing structure interposed between the tread portion and the crown region of the carcass plies. The crown reinforcing structure includes a belt assembly having at least a first, radially innermost and a second, radially outermost belt ply. The cords reinforcing the belt plies are preferably made of PET or PEN and have a linear density comprised between 2000 and 16000 Denier, a twist comprised between 2 and 7 TPI and a twist multiplier comprised between 3 and 5.

Abstract: The invention relates to a rubber tire composed of carbon black reinforced rubber carcass with an outer, circumferential rubber tread construction of a rubber composition having a relatively high electrical resistivity. The tire tread construction has electrically conductive filament stapled through the tread construction and extending between the inner surface of the tread to its outer surface. An electrically conductive path is thereby created through the tread.
