John Slocum 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).

  • Gas delivery system for an ion source
    Patent number: 8003954
    Abstract: An ion source has an arc chamber with an electron-emitting element and a repeller. A manifold assembly defines a cavity and a gas outlet configured to allow gas flow to the arc chamber. This gas outlet is closer to the repeller than the electron-emitting element. In one embodiment, the ion source has a first crucible and a second crucible. The first crucible and the second crucible are connected to the manifold assembly. In one instance, the crucibles have tamper-resistant features.
    Type: Grant

  • TECHNIQUES FOR MEASURING AND CONTROLLING ION BEAM ANGLE AND DENSITY UNIFORMITY
    Publication number: 20090121122
    Abstract: Techniques for measuring and controlling ion beam angle and density uniformity are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for measuring and controlling ion beam angle and density uniformity. The apparatus may include a measuring assembly having an opening, a cup, and at least one collector at the rear of the cup. The apparatus may further include an actuator to move the measuring assembly along an actuation path to scan an ion beam to measure and control ion beam uniformity.

  • Polymer concrete electrical insulator and method and apparatus for making
    Patent number: 5340512
    Abstract: An improved electrical insulator for high voltage transmission lines is formed from certain polymer-based concrete compositions. An apparatus provides for the molding of the polymer-based mixture to form a highly degassed product. The method and apparatus include the ability to combine the constituents of the mixture in a mixer. A vacuum is applied to the mixture to degas the mixture. A mold is filled with the degassed mixture without introducing air thereinto in the absence of a vacuum. The resulting insulator has highly reduced air entrainment.
