Patents by Inventor William C. Christie

William C. Christie 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).

  • Tire sidewall deformation detection techniques
    Patent number: 4475384
    Abstract: An improvement in a tire manufacturing system including means for testing the extent of sidewall deformation of a tire. The tire is rotated and measured for lateral runout of both sidewalls. The resulting data is converted to digital form and analyzed by groups in order to increase the accuracy by which unacceptable sidewall bulges and valleys are detected.
    Type: Grant
    Filed: July 11, 1983
    Date of Patent: October 9, 1984
    Assignee: The Goodyear Tire & Rubber Company

  • Automated tire measurement techniques
    Patent number: 4434652
    Abstract: An improvement in a tire manufacturing system including apparatus for testing by different combinations of testing algorithms and tire sensors. An operator selects the combinations best suited to test the tire according to the user's specifications. The tire is rotated and measured for lateral runout of both sidewalls. The resulting data is converted to digital form and analyzed according to the selected combinations of sensors and testing algorithms.
