  • Patent number: 6638490
    Abstract: A process for the selective production and isolation of high specific activity Cu67 from proton-irradiated enriched Zn70 target comprises target fabrication, target irradiation with low energy (<25 MeV) protons, chemical separation of the Cu67 product from the target material and radioactive impurities of gallium, cobalt, iron, and stable aluminum via electrochemical methods or ion exchange using both anion and cation organic ion exchangers, chemical recovery of the enriched Zn70 target material, and fabrication of new targets for re-irradiation is disclosed.
    Type: Grant
    Filed: September 18, 2002
    Date of Patent: October 28, 2003
    Assignee: The Regents of the University of California

  • Patent number: 6041687
    Abstract: An automatic bullet feeding mechanism is intended for use with a typical rifle or pistol cartridge reloading machine. More particularly, the bullet feeding mechanism of the present invention includes a generally cylindrical main housing which is adapted to be received within the main frame structure of the reloading machine. A reservoir attached to the upper end of the mechanism provides the main housing with a continuous supply of bullets. A pivoting lever arm, which includes a lower catch finger, is adapted to be received and mounted within a generally vertical groove formed in one side housing cylinder. Opposing the pivoting lever arm is an upper catch slide assembly which is movably mounted within a second generally vertical groove formed in the other side of the housing cylinder.
