METHOD AND APPARATUS FOR THE GENERATION OF ULTRASONIC ENERGY FIELDS WITHIN CIRCULAR STRUCTURES CONTAINING A LIQUID

摘要

A resonant chamber (12) 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 (16) 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.
