    Abstract: Methods and apparatus for cleaning brushes quickly, comfortably and efficiently are disclosed. The apparatus contains at least one cleaning chamber comprising a plurality of cleaning elements disposed within the chamber that contacts the brushes during cleaning, the cleaning chamber in contact with a) a drive and a motor that can deliver rapid reciprocating motions to the cleaning elements, b) a solvent flow system, and c) a removable brush holder connected to a motor that turns the brushes slowly over the cleaning elements. Rapid reciprocating motions of the cleaning elements, continuous flow of a solvent over the brushes to be cleaned and a slow rotation of the brush itself over the cleaning elements achieve rapid cleaning of brushes with little damage to the brush itself. A removable brush holder that can accommodate many different kinds of brushes in the same slot extends the functionality and comfort of using the brush cleaner.

    Abstract: An ultrasonic cleaning apparatus comprising: a tank for in use receiving a cleaning liquid and an item to be cleaned; a plurality of transducers arranged, when driven, to direct ultrasonic pressure waves into the tank; and a controller arranged in use to drive the transducers. First and second transducers from the plurality of transducers are arranged in use to direct ultrasonic pressure waves into an overlapping volume; and the controller is arranged in use to drive the first and second transducers to produce ultrasonic pressure waves at different frequencies from each other. The controller is arranged to in use produce first and second drive signals for the transducers using first and second frequency generators to each switch between primary and secondary operation, with the sequential switching taking place to cause different combinations of primary and secondary operation for the first and second frequency generators to occur over time.

    Abstract: The invention utilizes harmonics of certain clamped ultrasound transducers to generate ultrasound within the liquid of an ultrasonic tank and in a frequency range of between about 100 khz to 350 khz (i.e., “microsonic” frequencies). The application of microsonic frequencies to liquid preferably occurs simultaneously with a sweeping of the microsonic frequency within the transducer's harmonic bandwidth to reduce or eliminate (a) standing waves within the liquid, (b) other resonances, (c) high energy cavitation implosion, and (d) non-uniform sound fields, each of which is undesirable for cleaning and/or processing of semiconductor wafers and other delicate parts. The invention can also drive ultrasonic transducers such that the frequency of applied energy has a sweep rate within the ultrasonic bandwidth of the transducers; and that sweep rate is also varied so that the sweep rate is substantially non-constant during operation. This reduces or eliminates resonances which are created by transducers operating with a single sweep rate. An ultrasound generator of the invention sometimes utilizes amplitude modulation (AM), and the AM frequency is swept over time so as to reduce resonances. AM control is preferably provided by selecting a portion of the rectified power line frequency. In applications which utilize multiple generators, multiple transducers, and one or more tanks, simultaneously, the invention synchronizes the operation of the generators to a common FM signal to reduce beat frequencies between generators. Each such generator can also be adjusted, through AM, to control the process characteristics within the associated tank. Two or more transducers are sometimes used by the invention, in combination, to broaden the overall bandwidth of acoustical energy applied to the liquid around the primary frequency or one of the harmonics. The bandwidths of the transducers are made to overlap such that an attached generator can drive the transducers, in combination, to deliver ultrasound to the liquid in a broader bandwidth. In a single chamber ultrasound system, two or more generators, each operating or optimized to generate a different range of frequencies, are connected to a multiplexer; and the desired frequency range is selected, and hence the right generator, according to the cavitation implosion energy that is desired within the tank chemistry.
