Lamp-and-Switch System to Control Cathode Spraying

Panel indicator lamps in front of the operator at the cathode spraying position are actuated by quality control inspectors who measure the highly critical diameter and coating weight of finished cathode sleeves in the Bloomfield, NJ plant of Tung-Sol Electric Inc.

If the average ratings are within the dotted lines of the control chart a green light is given. If the average falls between the dotted and solid lines the the upper or lower yellow warning light is given. If the average falls above or below the area bounded by the solid control limit lines the upper or lower red light is given, and all spraying on that cathode type must stop until a corrective adjustment and spray time or spray pattern is made.
