In operation, the sheet is uniformly raised out of the bath while sliding in grooves in a support 19 to allow uniform etching over all its surface. A constant voltage, variable current at, e.g. 10-16V D.C. may be used.

Closure of relay 11 completes a holding circuit for itself and the relay 10, and instantaneous closure of relay 10 completes the circuit of the closing coil 7 of the switch 4. Closure of switch opens associated switch 11 thereby breaking the circuit of relays 10, 17, and relay 10 opens with a time delay. Closure of contacts 15 is effected by a shaded pole motor 19 energized from transformers 23, 24 according to the vector sum of the voltages of the alternator 6 and the system 3 and is opposed by a spring 30 and a motor 20 energized according to the vector difference. Momentary closure of contacts 16 is effected by a motor 32 opposed by a motor 33 respectively energized according to the vector sum and difference acting upon a disc 34 which is cut away at 51 and 52 so that upon movement of the disc under the predominating effect of one of the motors, the effect of the other motor is greatly reduced.
