tern of pulse control. Laboratory find- ings can be extrapolated to larger sizes. The A/min readout system is unique for arriving at the effective current available for electrodeposition. A 10-A current corresponds to 100 counts/min, and 1 count/min corresponds to 0.1 A.

As the reverse current is increased, the count rate decreases proportionately. Resettable totalizing and batch-type counters are featured. When the batch count equals zero, the current reaches zero as indicated by a pilot light. The cycle repeats when the batch count is reinstated.

immersion Cleaning Systems Tally Cleaning Systems A ffleboro Falls, Mass.

The Tally Cleaning Systems Aqua Lift, a mechanical-agitation, immer- sion-cleaning system utilizing aqueous cleaning solutions, is designed with

features to enhance service life, such as a control valve guaranteed for 200 million cycles and a lift/agitation cylin- der rated for 10 million ft of agitation strokes. This system is also designed to minimize operating costs by utilizing 80 psi compressed-air supply instead of the industry typical 100 or 125 psi. The system’s modular design permits customization to most processes and adaptation to process changes after the fact. Other features are a stainless steel tank and fiberglass insulation, both standard. Aqua Lift is available in three standard tank sizes and three standard lift capacities and can be modified for unique applications.
