  • Technique for interior electron sterilization of an open mouthed container
    Patent number: 6221216
    Abstract: Commercial sterilization of the interior surfaces of containers, cups or bottles by the use of energetic electrons is accomplished by directing electrons of moderate energies through the open mouth of such containers. Electrons which would normally illuminate the container beyond the inner diameter of the neck opening may be absorbed by a suitable electron-absorbing and cooled mask positioned above the container neck.

  • Compact, selfshielded electron beam processing technique for three dimensional products
    Patent number: 5825037
    Abstract: A compact, selfshielded electron beam processing technique for three dimensional products includes a treatment zone bounded by at least one material of high atomic number. Energetic electrons are directed into the treatment zone in such a manner that electron reflection from the boundary of the treatment zone assists in filling the treatment zone with energetic electrons. The products to be treated are caused to travel through the treatment zone without any mechanical contact therewith (such as by ballistic or pneumatic techniques).
