Patents by Inventor Neil McN Alford

Neil McN Alford 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).

  • Method of producing an electromagnetic signal
    Patent number: 6119025
    Abstract: A method of producing ceramic superconducting materials such as YBa.sub.2 Cu.sub.3 O.sub.x includes blending together starting materials for the superconducting material. The blend of starting materials are formed into a layer and sintered at a temperature above the peritectic temperature for the superconducting material. Prior to sintering, the starting materials for the superconducting material may be unreacted. The starting materials may also be partially reacted prior to sintering by calcining for a period of time at a temperature which does not result in full reaction of the starting materials to the chemical composition of the desired superconducting material.
    Type: Grant
    Filed: August 4, 1998
    Date of Patent: September 12, 2000
    Assignee: Illinois Superconductor Corporation
    Inventors: Timothy W. Button, Neil McN Alford, Felicitas Wellhofer
