Patents by Inventor Thad Alexander Heltemes

Thad Alexander Heltemes 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: 11238999
    Abstract: An apparatus for generating medical isotopes provides an annular fissile solution vessel surrounding a neutron generator. The annular fissile solution vessel provides for good capture of the emitted neutrons and a geometry that provides enhanced stability in an aqueous reactor. A neutron multiplier and/or a neutron moderator may be used to improve the efficiency and control the criticality of the reaction in the annular fissile solution vessel.
    Type: Grant
    Filed: June 7, 2019
    Date of Patent: February 1, 2022
    Assignees: Wisconsin Alumni Research Foundation, SHINE Medical Technologies, Inc.
    Inventors: Gregory Richard Piefer, Thad Alexander Heltemes, Eric Nicholas Van Abel, Ross Francis Radel

  • Patent number: 9330800
    Abstract: An apparatus for generating medical isotopes provides for the irradiation of dry-phase, granular uranium compounds which are then dissolved in a solvent for separation of the medical isotope from the irradiated compound. Once the medical isotope is removed, the dissolved compound may be reconstituted in dry granular form for repeated irradiation.
