Patents by Inventor Leon E. McCrary

Leon E. McCrary 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).

  • Patent number: 6435388
    Abstract: The present invention is directed to glove inflation apparatuses and methods for donning sterile gloves. The apparatuses includes at least one vacuum chamber that has an opening sized and shaped for receiving a glove and for establishing a fluid-tight seal between the glove and the vacuum chamber. The apparatuses further includes a vacuum pump which is connected to the chamber and a source of compressed gas which is in fluid communication with the glove. The apparatuses further includes a switch that is connected to the pump and the source of compressed gas. The switch has two states. In the first state, the switch permits the pump to evacuate the chamber. In the second state, the switch permits the source of compressed gas to expel the glove from the opening of the chamber.

  • Patent number: 5576600
    Abstract: An ion source has a peripheral wall, a back face and a front face which together define a plasma chamber extending along an axis. In one embodiment, a central aperture emits ions from plasma formed in a generally annular containment band about the aperture, and a plurality of magnets define magnetic field lines extending into the band, so that electrons traveling from the cathode are trapped in the band and highly effective ionization is achieved, producing high beam currents. An anode at the back of the source expels ions from the central region. In another or further embodiment, the plasma chamber has an anode plate which extends across the back of the source, and provides a broad expulsion field for expelling and preferably shaping a high current in ion output beam. A fluid inlet introduces an ionizable fluid in the peripheral region to interact with the trapped electrons, generating plasma with high efficiency.
