Abstract: An annular wedge suitable for use in a tire bead assembly preparation apparatus. The annular, resilient, flexible, compressible wedge has a generally T-shaped axial cross-section with an outer head portion, an inner trunk portion and an inner-connecting throat portion with a generally triangular cross-section therebetween, and a continuous reinforcing annular textile fabric strip integral with said head, throat and trunk portions, said wedge being of a continuous structure having a core of especially prepared microcellular polyurethane and an outer densified relatively smooth skin.
Abstract: A solid industrial polyurethane tire and a wheel assembly comprised of such a tire adhered to a rigid central core, or hub. The hub is generally adaptable to fit onto an axle of an industrial vehicle. Said polyurethane tire is prepared by reacting 2,2'-dithiodianiline with a prepolymer of selected diisocyanates and selected polymeric polyester and polyether polyols and their mixtures.
Abstract: A self-sealing pneumatic tire which comprises a tire casing having an integral, thin gauge, resilient closed cell structure disposed in its inward portion. Such a tire structure has particular utility for sealing against puncturing objects.
Abstract: A tire comprised of a composite structure of a cured rubber tire having adhered thereto a laminate of a cured polyurethane. Said laminate is prepared by (A) applying to the cured rubber tire a solution of a reaction mixture comprised of (i) an aliphatic primary diamine, (ii) a specified prepolymer utilizing a polycaprolactone polyol, and (iii) an organic solvent followed by (B) drying and curing the applied solution.

Abstract: A rubbery copolymer of butadiene, styrene and acrylonitrile, if desired, with a tensile strength of about 50 to about 100 psig containing a minor amount of styrene, particularly in combination with selective tackifier resins. Said copolymer is preferably prepared by a step-wise aqueous emulsion polymerization with styrene and modifier being incrementally added. Said rubbery copolymer/tackifier mixture is particularly useful as an adhesive.
Abstract: A cord composite suitable for rubber tire reinforcement comprised of a plurality of plies of yarns selectively cabled in a manner so that, upon application of longitudinal stress, at the initial elongation of the cable, the primary load bearing ply is a polyester or a nylon yarn and so that after appreciable elongation of the cable, the primary load bearing yarn is an aramid yarn. The invention further relates to a pneumatic rubber tire, industrial belt or hose having a carcass containing a fabric of such a cord as a reinforcing member.
Abstract: Method of treating ferrous based wire comprised of (A) electroplating a negatively charged ferrous based wire in a prescribed aqueous electrolyte solution containing a positively charged stationary anode and, in combination, simultaneously, in the same electrolyte solution, (B) deplating a similarly electroplated ferrous based wire by passing said plated wire as a supplemental, additional, positively charged, moving anode through said solution to effect a removal of its electroplated outer metal coating.
