Patent number: 7105595Abstract: Elastomer composite blends are produced by novel wet/dry mixing methods and apparatus. In the wet mixing step or stage, fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced.Type: GrantFiled: November 8, 2001Date of Patent: September 12, 2006Assignee: Cabot CorporationInventors: Melinda Ann Mabry, Ting Wang, Ivan Zlatko Podobnik, James A. Shell, Allan Clark Morgan, Bin Chung, Noboru Tokita

Publication number: 20030203992Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like. Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.Type: ApplicationFiled: July 2, 2002Publication date: October 30, 2003Inventors: Melinda Ann Mabry, Frederick Harry Rumpf, Ivan Zlatko Podobnik, Scott Adrian Westveer, Allan Clark Morgan, Bin Chung, Malcolm John Andrews, Ting Wang, James A.

Patent number: 5240534Abstract: Joining elastomeric sheets includes providing a support surface with a cavity therein. End portions of the elastomeric sheets are overlapped so each end portion spans the cavity. A tool is located on a side of the elastomeric sheets opposite the cavity. A portion of the tool is moved into the cavity to deform the end portions of the elastomeric sheets and to form a joint having less than the combined thickness of the end portions of the elastomeric sheets prior to deformation.Type: GrantFiled: February 6, 1991Date of Patent: August 31, 1993Assignee: Uniroyal Goodrich Tire CompanyInventors: Noboru Tokita, John R. Lindquist

Patent number: 5200009Abstract: An apparatus for building a tire comprises a supply of elastomeric sheet material of a predetermined length and having spaced apart first and second end portions. A plurality of parallel extending reinforcing members are contained in the elastomeric sheet material of which adjacent reinforcing members are spaced apart a substantially equal first distance. An embosser for elastically deforming the first and second end portions of the elastomeric sheet material increases the distance between the adjacent reinforcing members in each of the first and second end portions to a second distance greater than the first distance. A drum is provided to receive the elastomeric sheet material with the first and second end portions overlapped. A mold is provided to bond together the first and second end portions of the elastomeric material in the overlapped portion under heated pressure to form a joint.Type: GrantFiled: August 10, 1990Date of Patent: April 6, 1993Assignee: The Uniroyal Goodrich Tire CompanyInventor: Noboru Tokita
