Patents by Inventor Jack O. Schoenberger

Jack O. Schoenberger 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: 5140853
    Abstract: Actual valve stem thrust loads in a motor operated valve are monitored and measured directly by the use of load cells disposed directly between the valve and the operator. Direct measurement of stem thrust eliminates the errors associated with indirect methods. Analysis of actual thrust load measurements and correlation with other operating parameters, such as switch actuation and motor current, provides the capability to accurately calibrate valve operators and to detect valve and operator problems at an early stage.
    Type: Grant
    Filed: February 6, 1992
    Date of Patent: August 25, 1992
    Assignee: Westinghouse Electric Corp.
