Patents by Inventor Marvin M. Patnode

Marvin M. Patnode 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).

  • Refrigeration heat recovery system
    Patent number: 4018583
    Abstract: A combination vapor compression and refrigeration cycle employing a mechanical compressor for developing high temperatures. The suction end of the compressor is exposed to both the vapors discharged from the refrigeration evaporator and a mixture of oil foam and refrigeration vapors discharged from an absorption generator. As the mixture passes through the compressor, it absorbs the heat of compression and is discharged into a heat exchanger where energy is transferred to a reclaiming substance. Because of the absorptive process, relatively high temperatures are developed in the compressor discharge whereby the energy rejected into the reclaiming substance can be effectively utilized in domestic and industrial heating applications.
    Type: Grant
    Filed: May 24, 1976
    Date of Patent: April 19, 1977
    Assignee: Carrier Corporation
