Patents by Inventor Billy R. Howell

Billy R. Howell 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: 6478161
    Abstract: An eddy current separator apparatus for separating non-ferrous metals from other materials. The apparatus includes a support frame and a table cantileverly suspended from the frame. An expansion and contraction mechanism is incorporated that is adapted to accept a continuous conveyor belt thereabout. The expansion and contraction mechanism is capable of being configured between an operating configuration and maintenance configuration. A continuous conveyor belt is constructed to be able to be looped about the expansion and contraction mechanism and the table such that the conveyor belt is drawn tight in the operating configuration and slackened in the maintenance configuration. In this manner, the continuous conveyor belt is easily removable from, and installable onto the table in the maintenance configuration.

  • Patent number: 5522513
    Abstract: An apparatus for separating non-ferrous metal particles from residue composed of rubber, dirt, wood, plastic, glass, an the like, as well as the non-ferrous metal particles. The residue is transported by a conveyor belt over a pair of rotating magnetic separating discs which generate a magnetic field flux upward. This magnetic field flux induces an eddy current in the non-ferrous metal particles. The eddy current is a repulsive force to the magnetic field flux, which enables the non-ferrous metal particles to be levitated above the conveyor belt and the other residue material. The rotation of the field accelerates the particles off the side of the conveyor belt, into discharge chutes which collect the separated particles for recycling. The other residue material is collected at the end of the conveyor belt.
