  • Method and apparatus for the generation of ultrasonic energy fields within circular structures containing a liquid
    Patent number: 6736904
    Abstract: A resonant chamber that produces an ultrasonic energy field about a central axis of the chamber to separate contrary matter from a working material. The resonant chamber has a circular cross section and utilizes a series of transducer elements to generate an ultrasonic transverse wave disposed about the internal longitudinal axis of the chamber. In addition, a driver circuit is provided that is able to efficiently excite the transducer elements to generate the ultrasonic transverse wave with a minimum of heat dissipation and power loss.
    Type: Grant
