  • Foam molding shell for a centrifuge bowl, centrifuge bowl, method for producing a thermal insulation encasing a bowl of a centrifuge and centrifuge
    Patent number: 9993830
    Abstract: A foam molding shell for a centrifuge bowl, a bowl for a centrifuge, a method for producing a thermal insulation encasing the bowl for the centrifuge and to a centrifuge. The foam molding shell is configured as a disposable tool for foam encasing the bowl for the centrifuge with the thermal insulating material. Thus, the production complexity and the production cost of the centrifuge bowl with the thermally insulated bowl for the centrifuge can be significantly reduced.

  • Vibration damping for an electric device
    Patent number: 8791609
    Abstract: The present invention relates to an electrical device including a stator and a rotor, wherein the electrical device is preferably a generator, a motor or similar, in particular a centrifuge motor, wherein the rotor, in particular a motor shaft is rotatably supported through at least one bearing relative to the stator, wherein at least one damping device is provided between the stator and the rotor, wherein the damping device includes at least one damping element. Thus, the device provides a high level of integrated vibration damping and internal damping of the device can be adapted to particular properties and applications.
