Amr N. Abdelhamid 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).

  • Pressure variation absorber
    Patent number: 4504188
    Abstract: Pressure variation absorbing apparatus is mounted adjacent to a moving fluid stream in the diffuser of a centrifugal compressor for absorbing both acoustic and aerodynamic pressure variations. The absorbing apparatus when mounted as a part of the diffuser wall of a centrifugal compressor not only reduces acoustic noise but also absorbs aerodynamic pressure variations increasing the efficiency of the compressor and simultaneously reducing the rate of flow at which surge occurs thereby enlarging the operational flow range of the compressor. A method of absorbing pressure variations in a moving fluid stream is also disclosed.
    Type: Grant
    Filed: August 1, 1983
    Date of Patent: March 12, 1985
    Assignee: Carrier Corporation
    Inventors: Darwin G. Traver, Carl M. Anderson, Amr N. Abdelhamid
