Hans-Ruedi Zimmermann 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: 9568346
    Abstract: An assembly procedure for an electrode anchor, and a magnetic-induction flow meter, particularly for high pressure applications with medium pressures above 5.1 MPa (51 bar), having a measuring tube on which a multi-part electrode anchor for securing a measuring electrode is arranged. Included are: a) a coupling fitting, which is materially bonded to the measuring tube wherein the coupling fitting comprises a groove, or forms a groove together with the measuring tube; and b) a coupling insert for guiding and/or securing the measuring electrode the coupling insert being connected to the coupling fitting by way of a coupling. The coupling insert comprises anchoring wings which engage in the groove by a partial rotation and thereby effect the coupling.
    Type: Grant

  • Patent number: 8721168
    Abstract: In the case of a homogenizer device (100) for dispersing and/or homogenizing liquid to viscous substances, having a container (110) having one or more openings for introducing the substances to be processed, which has an opening for feeding the substances into a processing unit (120) in the central region of its bottom, which opening contains two gear rims (130, 140), which can be driven independent of one another, are disposed concentrically and configured in circular shape, and are separated from one another by way of a predetermined interstice, whereby the substances are guided from a central region, through the interstice, into a peripheral region of the gear rims, formation of cavitation is prevented, to the greatest possible extent, in that a conveyance device (150) is additionally provided in the processing unit (120), which device conveys the substances in the direction of the gear rims (130, 140), under pressure.
