Patents by Inventor Donald Neve

Donald Neve 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 and apparatus for variable frequency controlled compressor and fan
    Publication number: 20050086959
    Abstract: The present invention provides a variable frequency controlled refrigerant compressor in a dehydrator for compressed air or other cases. In particular, the present invention detects changes in a demand on the pneumatic air supply by monitoring a pressure of a refrigerant system associated with the air supply. Based on the changes in the refrigerant system pressure, a motor speed controller generates and sends a control signal to the variable speed compressor to adjust the speed of the variable speed compressor based on the demand in the air supply.
    Type: Application

  • Method and apparatus for variable frequency controlled compressor and fan
    Patent number: 6817198
    Abstract: Compressor controls in a compressed gas system provide a variable frequency controlled refrigerant compressor in a dehydrator for compressed air or other gases. The system detects changes in a demand on the pneumatic air supply by monitoring a pressure of a refrigerant system associated with the air supply. Based on the changes in the refrigerant system pressure, a motor speed controller generates and sends a control signal to the variable speed compressor to adjust the speed of the variable speed compressor based on the demand in the air supply.
