  • Apparatus and method for inspection of a material
    Patent number: 11709150
    Abstract: A method of inspecting a material includes examining a surface of a test material with an eddy current sensor and applying an X-ray fluorescence analysis to the surface of the test material at the same location at which the eddy current examination was performed.
    Type: Grant
    Filed: December 23, 2021
    Date of Patent: July 25, 2023
    Assignee: BWXT Nuclear Operations Group, Inc.
    Inventors: Paul D. Sheldon, Wayne M. Latham, Thomas C. Mohr, Aaron C. Havener, Richard Manzini, Timothy A. Policke

  • Detecting and classifying hard and soft inclusions in liquid metal
    Patent number: 6337564
    Abstract: Apparatus and method for providing a classification of inclusions in molten metal. The apparatus and method include the steps of and means for obtaining an analog signal stream from a data collection apparatus, passing the analog signal stream through an analog to digital converter to convert the analog signal stream to a digital signal stream, and partitioning the digital signal stream into a discrete time frame of 5 milliseconds. The digital signal stream is vector normalized to provide a normalized signal stream having a largest amplitude magnitude of 1. The normalized signal stream is compared to a control of a prototype shape for determining a classification for the digital signal stream over the discrete time frame by decision logic to determine hard inclusions versus soft inclusions in the liquid metal.

  • Die-casting process and equipment
    Patent number: 5370171
    Abstract: The die casting machine includes a trough containing a supply of molten metal and a feed tube extending into the supply of molten metal in the trough. A flow of molten metal is maintained in the trough past the feed tube independent of the transfer of molten metal through the feed tube. The die casting machine further includes a filtering system.
