Patents by Inventor Emil W. Ritzi

Emil W. Ritzi 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).

  • Multi-stage, wet steam turbine
    Patent number: 4441322
    Abstract: A multi-stage, wet steam turbine employs working fluid, such as steam for example, in its two-phase region with vapor and liquid occurring simultaneously for at least part of the cycle, in particular the nozzle expansion. A smaller number of stages than usual is made possible, and the turbine may handle liquid only. Simple construction, low fuel consumption and high reliability are achieved.
    Type: Grant
    Filed: January 12, 1981
    Date of Patent: April 10, 1984
    Assignee: Transamerica Delaval Inc.
    Inventor: Emil W. Ritzi

  • Two-phase reaction turbine
    Patent number: 4298311
    Abstract: A reaction turbine includes(a) first nozzle means to receive heated fluid for expansion therein to form a two-phase discharge of gas and liquid,(b) a separator rotor having an axis and a rotating surface located in the path of said discharge for supporting a layer of separated liquid on said surface,(c) the rotor having reaction nozzle means to communicate with said layer to receive liquid therefrom for discharge in a direction or directions developing torque acting to rotate the rotor.
