Peter Zehnel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8845967
    Abstract: The present relates to a container and to a device for indirect material cooling and to a method for producing the container according to the invention. Through the present invention a much more efficient indirect heat transfer is facilitated from the exterior of the container into the interior of the container. The improvement of the heat conductivity and of the heat transfer of centrifuge containers yields a reduction of the necessary power of the refrigeration system for cooled centrifuges. Through the higher performance of the centrifuge a higher speed can be run for identical centrifuge temperatures and/or at the same centrifuge temperature and speed, the input power of the refrigeration unit can be reduced.

  • 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.
