Abstract

An elongated workpiece is passed through the axis of a cylindrical ultrasonic transducer in a conduit containing solvent agent for ultrasonic cleaning. The cleaning action is performed with liquid solvent in a blanket of saturated vapor maintained by a solvent boiling sump, while the transducer is kept isolated from the vapor by a special compartment communicating only with the atmosphere for air cooling. Vestibules allow an overflow of solvent from the conduit in entry and exit chambers traversed by the workpiece and circulation of condensate is maintained to and from a storage sump of liquid solvent.
