Patents by Inventor Raymond J. Koski

Raymond J. Koski 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).

  • Material compaction apparatus
    Patent number: 7011018
    Abstract: The material compactor generally includes a feed apparatus and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having confronting compression plates and an adjustably taperable portion. The area of the inner cavity of the final compaction chamber can be adjusted to become measurably smaller (tapered) or larger at the opened discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the chamber significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus and out an open discharge port.
    Type: Grant

  • Material compaction apparatus
    Patent number: 6948424
    Abstract: The material compactor in accordance with the present invention generally includes a feed apparatus, a preliminary compaction apparatus, and a final compaction apparatus. The final compaction apparatus generally includes a compaction chamber having an adjustably taperable choke tube. The area of the inner cavity of the final compaction chamber can be tapered to become measurably smaller or larger at the discharge or expelling end. Consequently, compacting movement of the material within the compaction chamber and through the tapered choke tube significantly subjects the material to restrictive compacting pressure which in turn compacts the material and performs liquid separation with each operationally continuous movement through the final compaction apparatus.
