  • Starch composite reinforced rubber composition and tire with at least one component thereof
    Patent number: 5672639
    Abstract: The present invention relates to a rubber composition containing a starch/plasticizer composite and to pneumatic tires having at least one component comprised of such rubber composition. Such tire component can be, for example, its circumferential tread or other component of the tire.The starch/plasticizer composite can be a composite of starch and plasticizer such as, for example, poly(ethylenevinyl alcohol) and/or cellulose acetate or any suitable plasticizer which results in such starch/plasticizer composite having a melting point below that of the starch alone, and particularly below about 160.degree. C., and to thereby enable the starch to be more processable with conventional elastomer composition processing equipment.

  • Method of attachment of flexible member to stamped steel piston
    Patent number: 5671907
    Abstract: An air spring assembly having a flexible member and moveable piston is provided. A bead surface of the flexible member is secured into a channel in the moveable piston to create an air-tight seal which can withstand tensile stress. The hollow piston increases the volume of the air reservoir which contributes to a reduction in the spring rate.
