Patents by Inventor Eric L. Bush

Eric L. Bush 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).

  • Capacitors
    Patent number: 4584074
    Abstract: Ceramic capacitors are formed from electrodeposited ceramic dielectric layers that are provided with electrodes, stacked and fired. Contact to the electrodes is provided by each terminations and leads. As the electrodeposition process is self limiting and self heating, uniform pinhole free dielectric layers are obtained.
    Type: Grant
    Filed: January 30, 1985
    Date of Patent: April 22, 1986
    Assignee: International Standard Electric Corporation
    Inventors: Henley F. Sterling, Eric L. Bush, John H. Alexander
  • Fluidizing fine powder
    Patent number: 4379186
    Abstract: Powder which is too fine to be fluidized on its own is fluidized admixed with a sufficient quantity of coarser powder of a particle size that can be fluidized on its own. The process may be used for coating fine powders with valve-metal for the manufacture of capacitor electrodes.
    Type: Grant
    Filed: March 10, 1981
    Date of Patent: April 5, 1983
    Assignee: ITT Industries, Inc.
    Inventors: Eric L. Bush, Ernest J. Workman
  • Coating powder with valve-metal
    Patent number: 4353938
    Abstract: Powder is coated with valve-metal by rotating it in a drum 15 so that it is presented to valve-metal vapor derived by evaporation of a source of valve-metal. In the case of coating with aluminum, the vapor may be produced by directing aluminum wire 10 on to a heater 11, and oxygen or air is admitted to control agglomerate formation. Aluminum and tantalum coating are both described using electron beam evaporators.
    Type: Grant
    Filed: July 28, 1980
    Date of Patent: October 12, 1982
    Assignee: International Standard Electric Corporation
    Inventors: Henley F. Sterling, Eric L. Bush, Miles P. Drake, Denis W. J. Hazelden, Sarah Y. Hughes
  • Coating powdered material
    Patent number: 4338354
    Abstract: A process for coating a particulate insulating material, e.g. alumina, with a uniform layer of a valve metal. The particles are exposed to a gaseous nitrogen compound, or to nitrogen gas together with hydrogen and a volatile halide of the valve metal. It is thought that nitrogen provides nucleation of the surface for subsequent metal deposition. The coated powder may be used in the fabrication of electrolytic capacitor anodes.
    Type: Grant
    Filed: April 28, 1980
    Date of Patent: July 6, 1982
    Assignee: International Standard Electric Corporation
    Inventors: Eric L. Bush, Ernest J. Workman
  • Electrolytic capacitors
    Patent number: 4214293
    Abstract: A solid electrolytic capacitor has a porous anode body manufactured from a valve metal coated core by pressure compaction of the metal powder at 25 to 40 tons per square inch. No subsequent sintering is required by this process.
