Patents by Inventor Henry Bernatowicz

Henry Bernatowicz 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).

  • Signature surveillance of nuclear fuel
    Patent number: 4347622
    Abstract: Typical nuclear fuel material contains tramp ferromagnetic particles of random size and distribution. Also, selected amounts of paramagnetic or ferromagnetic material can be added at random or at known positions in the fuel material. The fuel material in its nonmagnetic container can be scanned by magnetic susceptibility change detecting apparatus to provide a unique signal waveform of the container of fuel material as a signature thereof. At subsequent times in its life, the container similarly can be scanned to provide subsequent signatures. Comparison of the signatures reveals any alteration or tampering with the fuel material.
    Type: Grant
    Filed: April 7, 1980
    Date of Patent: August 31, 1982
    Assignee: General Electric Company
    Inventors: Henry Bernatowicz, Frederick C. Schoenig, Jr.
  • Determining paramagnetic additive content of a base paramagnetic material containing ferromagnetic impurity
    Patent number: 4243939
    Abstract: Method and apparatus for the nondestructive determination of the amount and quantitative distribution of a paramagnetic additive such as gadolinia in nuclear fuel elements. Changes in paramagnetic susceptibility of the material in the element are detected as the element is passed through a constant magnetic field and compared to the changes in susceptibility produced by a standard element of known additive content.
