Abstract: This invention relates to a tire with a rubber sidewall having at least one layered rubber composite integral with a portion of its outer surface as a means of visibly identifying the tire. The layered composite is an integral composite in a sense of being comprised of a base rubber layer and a contrastingly colored marking rubber layer being partially pre-cured together prior to application to the outer surface of an uncured rubber sidewall. The integrally layered composite and tire rubber sidewall are integral in a sense of being co-cured together with the surface of the base rubber layer facing the rubber sidewall surface. The base rubber layer is a black colored carbon black reinforced rubber layer. The marking rubber layer is of color which contrasts with the black color of the base rubber layer.

Abstract: An electrical connection is provided for connecting electrically transmitting cables and/or wires to one another or any other component in a manner that provides an environmentally sealed connection. The electrical connection includes an electrical connector for connecting electrical cables or wires that includes seals which are disposed in grooves in the threaded portions of the electrical connector. The electrical connector may also include a second set of grooves separated from the first set of grooves, in order to cause moisture and other debris to migrate away from the seals. When the end connectors of electrical cables or wires are connected to the electrical connector, the interior threads of end connectors cover and deform the surface of the seals to create an enhanced seal between the connector and the end connectors.

Abstract: This invention relates to a pneumatic tire having a built-in non-black colored sealant layer and its preparation. The sealant layer is derived from a sealant precursor layer comprised of a butyl rubber, organoperoxide, particulate, synthetic amorphous silica and plant-derived organic agricultural seed flour, together with a non-black colored colorant. The butyl rubber-based sealant precursor layer is build into the tire to form a tire assembly and the butyl rubber component of the sealant precursor layer is depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant. The particulate plant derived organic agricultural seed flour is a renewable raw material in a sense that it can be replenished in nature and therefore not as a significant depletion of non-renewable natural resource. The agricultural plant seed flour is comprised of at least a portion of a ground plant seed (e.g.

Abstract: This invention relates to a pneumatic tire having a built-in sealant layer and its preparation. The sealant layer precursor is a layer of a butyl rubber based composition which contains an organoperoxide. The butyl rubber of said precursor is a copolymer of isobutylene and isoprene containing from about 0.5 to about 5, alternately less than 1, mole percent isoprene. The precursor composition contains carbon black and/or coal dust and may contain a dispersion of liquid conjugated diene polymer (e.g. liquid cis 1,4-polyisoprene polymer), short fibers and/or hollow glass microspheres. A layer of the sealant precursor is built into the tire between a sulfur vulcanized halobutyl rubber innerliner and conjugated diene-based rubber of the tire carcass. The butyl rubber of the sealant precursor is partially depolymerized by the organoperoxide during the elevated temperature vulcanization of the tire to form the built-in sealant layer.
