Abstract: The invention provides systems, methods and apparatus for processing delicate parts within a process tank such as an ultrasonic tank. Typically, one or more transducers connect to the tank and respond to drive signals from a generator to produce ultrasound within process liquid within the tank. Specific features of the invention include: (1) a power up-sweep ultrasonic system for moving contaminants upwards within the tank by sweeping transducer drive signals from an upper frequency to a lower frequency without sweeping from the lower frequency to the upper frequency; (2) a multi-generator system for producing ultrasound at selected different frequencies within the tank by switching a common transducer bank to one of the generators in response to remote relays initiated by the user; (3) a probe sensing system for sensing process conditions within the tank including an enclosure for housing a sample liquid and one or more sensing transducers within the sample liquid, the transducers generating signals indicative of characteristics of the sample liquid, a subsystem analyzing the signals in feedback with the generator to modify process conditions; (4) variable voltage ultrasonic generator systems to accommodate varying world-wide voltage supplies; (5) a laminar process tank for efficiently pushing contaminants upwards in a tank; (6) a quick dump rinse tank including a pressure cavity to accelerate dumping processes; (7) an ultrasonic generating unit formed of a printed circuit board (PCB) and multiple transducers within the PCB; (8) an AC power system to produce an AC voltage at frequency f that is impressed across a capacitive element; and (9) various configurations of transducers, including acid-safe transducers, double-compression transducers, and transducers with increased reliability.

Abstract: An oscillator circuit is provided for ultrasonic apparatus such as ultrasonic cleaners employing a resonant transducer. The circuit includes a pair of transistors connected in series to a source of power with the transducer connected across one of the transistors in series with the primary winding of a transformer which has secondary windings connected in opposite polarity to the bases of the transistors so that one transistor is saturated while the other is nonconducting. The circuit accordingly oscillates at substantially the resonant frequency of the transducer as a result of the feedback provided by the secondary windings of the transformer.
