Nabil Abdelmonem 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).

  • Apparatus for producing ion exchange particles charged with uranyl ions
    Patent number: 4514296
    Abstract: An apparatus charges weakly acidic cationic ion exchange resin particles with uranyl ions by contacting the particles stepwise with aqueous uranyl nitrate solution at higher uranium concentrations from stage to stage. An alkaline medium is added to the uranyl nitrate solution in each stage to increase the successive pH values of the uranyl nitrate solution contacting the particles in dependance upon the uranium concentration effective for maximum charging of the particles with uranyl ions.
    Type: Grant
    Filed: January 5, 1981
    Date of Patent: April 30, 1985
    Assignee: Kernforschungsanlage Julich, Gesellschaft mit beschrankter Haftung
    Inventors: Helmut Ringel, Erich Zimmer, Nabil Abdelmonem
  • Method of producing weakly acidic cation exchange resin particles charged with uranyl ions
    Patent number: 4279866
    Abstract: Weakly acidic cationic ion exchange resin particles are charged with uranyl ions by contacting the particles step wise with aqueous uranyl nitrate solution at higher uranium concentrations from stage to stage. An alkaline medium is added to the uranyl nitrate solution in each stage to increase the successive pH values of the uranyl nitrate solution contacting the particles in dependence upon the uranium concentration effective for maximum charging of the particles with uranyl ions.
