  • Publication number: 20040178151
    Abstract: A material separator includes a chamber and electrode(s) to create a radially oriented electric field in the chamber. Coils are provided to generate a magnetic field in the chamber. The separator further includes a launcher to propagate a high-frequency electromagnetic wave into the chamber to convert the material into a multi-species plasma. With the crossed electric and magnetic fields, low mass ions in the multi-species plasma are placed on small orbit trajectories and exit through the end of the chamber while high mass ions are placed on large orbit trajectories for capture at the wall of the chamber.
    Type: Application

  • Publication number: 20040077916
    Abstract: A method and system for increasing the waste loading of vitrified nuclear waste includes a plasma mass filter and a heating apparatus. The plasma mass filter is used first to collect radioactive particles from a multi-species plasma. The radioactive particles are then placed, together with a frit, in crucibles. The crucibles are then induction heated to fuse the radioactive elements with the frit to form a melted mixture which is then cooled to form vitrified waste having relatively high waste loading.

  • Patent number: 6592364
    Abstract: The present invention is an apparatus for distributing air to different regions of a conveyor oven. The apparatus has comprising one or more blowers to distribute the air. A lower plenum is connected to a blower. The lower plenum directs air to the lower side of a conveyor within the oven. An upper plenum is connected to a blower. The upper plenum directs air to the upper side of the conveyor.

  • Patent number: 6576874
    Abstract: A modular heater for a conveyor oven has a flange that is removably attachable to the conveyor oven. The flange has an interior surface and an exterior surface. A heating element is attached to the interior surface of the flange. At least one contact is attached to the exterior surface of the flange. The contact is electrically connected to the heating element.

  • Publication number: 20030041851
    Abstract: The present invention is a conveyor oven that has a base. The base has a first end and a second end. A housing is secured to the second end of the base. A fixed end of a cantilevered top is attached to the housing. The cantilevered top extends generally parallel to the base and towards the first end of the base. The volume between the cantilevered top and the base generally defines an oven chamber.
