  • Patent number: 10683857
    Abstract: A pump device, in particular for a brake system of a motor vehicle, includes two hydraulic chambers, a linear drive, and a pump piston. Each of the chambers has at least two fluid connections. The pump piston interacts with the chambers. The linear drive is embodied as a reluctance drive and includes a longitudinally movable armature, a housing-fastened stator that is configured to receive current, and at least one spring element. The at least one spring element is associated with the armature, and is configured to counteract a drive force of the reluctance drive. The armature is connected to the pump piston.

  • Publication number: 20030008984
    Abstract: The invention relates to a catalyst system, containing at least one metallocene, at least one co-catalyst, at least one supporting material and optionally additional organometallic compounds. The catalyst system can be used advantageously for polymerising olefins, as it obviates the use of aluminoxanes, such as methylaluminoxane (MAO), which is conventionally used in excess quantities as a co-catalyst, whilst at the same time producing strong catalyst activity and excellent polymer morphology.
