ABSTRACT:
An improvement in ultrasonic cleaning in which articles to be cleaned are immersed in a bath subjected to ultrasonic energy emanating from ultrasonic transducers coupled to a vibratory diaphragm contiguous with the bath, the ultrasonic transducers being in multiple sets for providing ultrasonic energy at multiple ultrasonic frequencies at interspersed locations spaced apart a distance enabling the multiple sets of transducers simultaneously to transmit to the bath ultrasonic energy at the multiple ultrasonic frequencies without deleterious interference arising out of the simultaneous presence of the multiple ultrasonic frequencies.
