Patents by Inventor Timothy R. Branam

Timothy R. Branam 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).

  • Method and apparatus for monitoring and measuring dynamic loads in thrust inducing systems
    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.
    Inventors: Timothy R. Branam, Jeffrey J. Roberts, Jack O. Schoenberger

  • Electronic torque switch
    Patent number: 4987358
    Abstract: An electronic torque switch provides substantially enhanced control in an electric motordriven torque supplying system. Utilizing an accurate and real time measurement of motor operating power, a correlation may be made with the output torque to control operation of the motor. The switch may use an operating signal based either on the absolute level of operating power or on the rate of change of operating power to control, for example, valve seating thrust levels in a motor operated valve.
