Patent number: 11180639Abstract: The present invention provides a process for making a silica masterbatch that contains hydrophobated silica, solution-made rubber and emulsion-made rubber. Hydrophobated silica is mixed into a latex emulsion. Solution-rubber crumb in an aqueous suspension is mixed into the latex emulsion, which is coagulated, and a crumb is recovered, further homogenized, dried and baled to yield the silica masterbatch. A well-dispersed mixture of hydrophobated silica and emulsion-made rubber is added into a steam distillation step of a solution-rubber process from which a silica masterbatch is recovered. The emulsion-made rubber can be omitted to make a silica masterbatch of solution rubber and silica without emulsion rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition.Type: GrantFiled: July 2, 2019Date of Patent: November 23, 2021Assignee: Industrias Negromex, S.A. de C.V.Inventors: Christopher J. Hardiman, Xuan Fu, Robert J. Scribner, Julian Maldonado Valenzuela

Patent number: 4020354Abstract: Apparatus for treating running lengths of tire ply stock, gum stock, chafer, chipper, and similar components of diverse widths by electron radiation from a high voltage electron accelerator in a shielded chamber, facilitates handling by plural parallel conveyors which can operate individually for lesser widths or in synchronism as one conveyor to carry greater widths through the treatment chamber. Letoff and windup units are associated with individual conveyors and with the combined conveyors.Type: GrantFiled: September 13, 1976Date of Patent: April 26, 1977Assignee: The Goodyear Tire & Rubber CompanyInventors: Glenn C. Fauss, Robert J. Scribner
