  • Patent number: 8075992
    Abstract: Cured perfluoroelastomer articles are disclosed which have improved surface characteristics. The articles are coated with a thin durable film comprising a fluorocarbon telomer which reduces surface stickiness, while maintaining the sealing properties of the article.
    Type: Grant
    Filed: March 4, 2008
    Date of Patent: December 13, 2011
    Assignee: DuPont Performance Elastomers LLC
    Inventors: Kaori Iwamoto, Bunichi Rai, Shinichi Sogo

  • Patent number: 6946511
    Abstract: Elastomeric parts having a magnetic flux density of at least 10 gauss on their surface deflect a portion of reactive plasmas from contact with the surface of the parts. Thus, such parts may be exposed to reactive plasmas for longer periods, with less degradation, than may similar elastomer parts that do not have such a magnetic flux density on their surface.

  • Patent number: 6503972
    Abstract: A highly durable, high whiteness elastomer seal material molded from a composition comprising a perfluoroelastomer and a white pigment and having a surface with a whiteness of at least 90 as expressed by a W (Lab) color expression system under the conditions of a 2 degree field of view and a C-light source.

  • Patent number: 5050852
    Abstract: A blank feeder for feeding blanks. It has a feed table on which a plurality of blanks are stacked, a suction unit provided under the table to suck the lowermost one of the stack downward, a motor-driven first feed rolls mounted in the suction unit and adapted to feed the lowermost blank in contact therewith, and second feed rolls located downstream of the first feed rolls and adapted to be driven at a constant speed. The first feed rolls are accelerated from zero speed to the speed of the second feed rolls before the front end of the blank reaches the second rolls, then driven synchronized with the second feed rolls, and decelerated to zero speed again by the time the next cycle begins. A kicker for pushing out the blank may be provided. The kicker is moved forward so as to be synchronized with the second feed rolls before the front end of the blank reaches the second feed rolls. Once synchronized, this state is maintained until the rear end of the blank gets off from the kicker.
