Rick Cox 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).

  • Bypass system for engine startup
    Patent number: 11920509
    Abstract: Systems, methods and apparatus are disclosed for providing reduced engine start times for a fumigation type internal combustion engine. A bypass is provided that directly connects the air-fuel mixer upstream of the compressor to the intake manifold, providing the air-fuel mixture to the intake manifold during engine startup.

  • Determination of coal bed natural gas production factors and a system to determine same
    Patent number: 8640771
    Abstract: Well fluids in coalbed natural gas reservoirs and other carbonaceous reservoirs are analyzed to determine production factors such as gas content, critical desorption pressure, and/or other reservoir and operational variables. In particular, the partial pressure of methane or a predictor substance, or a methane concentration, are measured and/or determined for the wells and production factors are determined therefrom.

  • Method and apparatus for desorbing methane from coal formations via pressure waves or acoustic vibrations
    Publication number: 20050098314
    Abstract: One embodiment of this method involves using an acoustic device (including devices that emit acoustic waves at subsonic, sonic, and ultrasonic frequencies) that induces pressure changes at high frequencies. Those pressure changes could be induced across a large area from a single device location. Thus, one acoustic device located in one wellbore can desorb gas from a large volume of coal.
