Claim 1
Independent Claim
256 words
A time accumulator control for electrolytic process comprising: a current generator; electrolytic plating means including: a cathode forming tank, an anode disposed within said tank, said anode and cathode being electrically connected to the current generator; power means, means including first switch means interconnecting the power means and the current generator; time multiplying means operatively connected to the switch means and responsive to a first input signal of given time duration, which time multiplying means includes: a reversible motor having clockwise and counterclockwise input terminals; a voltage source; voltage control means interconnecting the said voltage source and the motor, and a second switch means operatively connected to the voltage control means for applying a first voltage to the clockwise terminal of the motor and a second voltage to the counter-clockwise terminal of the motor; a first input signal of given time duration comprising: a voltage source, control means operatively connected to the voltage source, and means interconnecting the voltage source to the second switch means for operation thereof; third switch means operatively connected to the current generator for controlling the operation thereof, color sensing means, including a light source disposed and positioned so as to direct a beam of light through the said tank, photoelectric switching means disposed to receive the said light and operatively connected to the third switching means for controlling the operation thereof, and fourth switch means operatively connected to the current generator for controlling the current produced thereby, said switch means being responsive to a second input signal of given time duration.
