Robert J. Eichelberger 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).

  • Apparatus for compaction of ceramic
    Patent number: 5162118
    Abstract: An apparatus for the production of high density, monolithic ceramic maters. A mixed powder, such as Titanium-Boron is first subjected to uniaxial pressure to form a green compact. The compact is positioned in a vented mold between two steel plates and subjected to Self-Propagation High Temperature Synthesis to form a molten ceramic, and then to an explosively generated shockwave by an explosive charge positioned on the upper steel plate so as to compress the molten ceramic between the two plates to form high purity ceramic of more than 90% theoretical density.
    Type: Grant
    Filed: July 25, 1991
    Date of Patent: November 10, 1992
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Andrus Niiler, Gerard L. Moss, Robert J. Eichelberger
  • Fabrication of ceramics by shock compaction of materials prepared by combustion synthesis
    Patent number: 5114645
    Abstract: A method and apparatus for the production of high density, monolithic cerc materials. A mixed powder such as Titanium-Carbon is first subjected to uniaxial pressure to form a green compact. The compact is positioned in a vented mould between two steel plates, reacted by a combustion synthesis process called SHS and then subjected to an explosively generated shockwave by an explosive charge positioned on the upper steel plate, which generates high pressures to compress the hot, porous ceramic to form high purity ceramic of more than 90% theoretical densities.
