Patents by Inventor Kai Marschner

Kai Marschner 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.
    Type: Grant
    Filed: June 29, 2012
    Date of Patent: September 30, 2014
    Assignee: Eppendorf AG
    Inventors: Bert-Olaf Grimm, Peter Zehnel, Kai Marschner
  • Patent number: 8783737
    Abstract: A closure lock, in particular to a lock for a cover of a laboratory centrifuge and a housing of the laboratory centrifuge. The closure lock provides a particularly effective, loadable and safe lock which is not only actuatable through a power drive, but which also provides robust self blocking with respect to strong vibrations and high crash energies.

  • Publication number: 20110160030
    Abstract: A laboratory centrifuge according to the invention provides much better de-mixing rates of centrifuged samples since providing at least one rotation compressor introduces substantially less vibration into the laboratory centrifuge, so that much lower remixing rates are provided.
