Abstract: The invention relates to an endless vehicular rubber track. The invention particularly relates to such track having hard rubber guide lugs with a softer guide support layer. It is to be appreciated that such guide lugs may also be positively driven drive lugs. The invention further relates to a vehicle having such track.

Abstract: The invention relates to an endless vehicular rubber track designed for extreme cold temperature working environment. The invention particularly relates to such track having a combination of tread, supporting carcass and guide lug components of rubber compositions intended for such purpose.

Abstract: The invention relates to a two part endless vehicular rubber track comprised of a polyurethane based tread component and a rubber carcass component. In one aspect, the tread component may be comprised of a sulfur curable polyurethane or blend of sulfur curable polyurethane and sulfur curable elastomer. The invention includes a vehicle containing such track.

Abstract: A rubber tire is provided which contains an electrically oriented composite within a rubber composition component of the tire, wherein said composite is composed of at least two electrically conductive metal elements in close proximity to each other and an electrically conductive rubber composition which is in contact with and electrically connects said metal elements together. The invention also contemplates an electrically resistive rubber composition within said tire rubber component which is juxtapositioned to at least a portion of said electrically conductive rubber composition and to at least a portion of at least one of said electrically conductive metal elements.

Abstract: A substantially solid industrial polyurethane tire/wheel assembly where said polyurethane is prepared by reacting (A) a curative of 1,3-propane diol with a prepolymer of diphenylmethane-4,4'-diisocyanate and a polymeric polyol or (B) a curative complex of 4,4'-methylene dianiline with a prepolymer of a diisocyanate selected from diphenylmethane-4,4'-diisocyanate and toluene diisocyanate with a polymeric polyether polyol. It is an important feature of this invention that the selection of reactants involved, for the dianiline complex, a partial substitution of the polyether polyol with a polyether-ester polyol.
