ABSTRACT:
An ultrasonic pulse cleaner has a driving circuit which receives current from a source and drives an ultrasonic energy generating element. A timer connected to the driving circuit permits operation in a first mode in which the ultrasonic energy generating element generates ultrasonic energy at a substantially continuous rate, and in a second mode in which the ultrasonic energy generating element generates ultrasonic energy as a plurality of discrete pulses.
