  • Patent number: 8123971
    Abstract: The invention relates to composites made of an elastic carrier medium comprising polynorbornene (PNR) and magnetisable particles which are polarized reversibly in a magnetic field. Thus the mechanical properties, such as e.g. storage modulus G? (describes the elastic behavior or the energy storage) and loss modulus G? (describes the viscous behavior or the energy dissipation), of such elastomer composites can be increased rapidly and reversibly within wide limits (up to approx. two orders of magnitude) as a function of an external magnetic field. Wide-ranging application possibilities are produced herefrom, e.g. for adaptive damping systems, in which the damping force can be adjusted via the strength of the magnetic field.

  • Patent number: 5252649
    Abstract: The plasticizer constituent in the rubber mixture of the tread member of a pneumatic vehicle tire contains at least partially at least one fatty acid triglyceride, preferably natural rape seed oil in which more than 50% of the fatty acid residues are present as oleic acid residues and an oleic acid/linoleic acid ratio is greater than or equal to 2:1. Sunflower seed oil or natural rape seed oil and triglyceride of oleic acid also can be used as the fatty acid triglycerides. There is thus achieved improved traction upon ice and snow as well as at dry and wet roads in the absence of negative effects on other properties of the tire.
