  • Thermoplastic elastomers
    Patent number: 4745149
    Abstract: Thermoplastic elastomers made of 48 to 88% by weight of ethylene-propylene-diene-rubber (EPDM), 10 to 50% by weight of polypropylene (PP) and 2 to 20% by weight of a third polymer and 5 to 60% by weight of softening oil, based on the total of EPDM, PP and the third polymer, and optionally further conventional constituents, have the advantage that the softening oil does not exude.
    Type: Grant
    Filed: September 2, 1986
    Date of Patent: May 17, 1988
    Assignee: Bayer Aktiengesellschaft
    Inventors: Ulrich Eisele, Dieter Jache, Ludwig Mott, Karl-Heinz Schabel
  • Absorber with suction pump
    Patent number: 4188196
    Abstract: In order to control noxious substances in the air, the air to be monitored is continuously drawn through an absorber. An absorber with a suction pump connected downstream is used for this purpose. A particularly small and compact device composed of an absorber and suction pump may be obtained by forming the inlet valve and outlet valve of the suction pump as O-ring disc valves and by providing the pump drive with a light barrier.
