ABSTRACT:
A plurality of generally cylindrical parallel tubs are arranged in horizontally adjacent relation and define corresponding chambers for receiving loads of parts and treating media. The tubs are rigidly connected and are supported by a set of springs to provide a neutrally statically stable tub system which oscillates at a predetermined resonant frequency on an axis extending substantially through the center of gravity of the tub system. Preferably, the oscillatory tub system is excited at substantially the resonate frequency by a set of electro-magnets which are arranged in opposng relation on opposite sides of an armature positioned below the tubs and within a vertical plane extending through the pivot axis. The springs may include a set of spring beams located at opposite ends of the tubs to provide the effective pivot axis and/or a set of coil springs which are located laterally outboard of the tubs and are positioned normally to a plane extending through the coincident pivot axis and center of gravity of the tub system.
