Abstract A CONVENTIONAL SPIRAL VIBRATORY CONVEYOR IS IMMERSED INTO AN ELECTROLYTIC TANK, TO AUTOMATICALLY TIME AND ELECTROLYTIC OPERATION CARRIED OUT OF MOVING MASSES OF SMALL METAL PARTS. TYPICAL OPERATIONS INCLUDE DE-ELECTROPLATING OR STRIPPING TIN COATINGS FROM BITS OF COPPER WIRE, AND THE ELECTROPLATING OF NUTS. AS THE MASS OF METAL PARTS IS VIBRATED UPWARD, CONDUCTIVE CONTACT IS MADE, IN THE INTERVALS BETWEEN SUCCESSIVE VIBRATORY PULSES, WITH ELECTRODE MEANS ON THE SPIRAL FLIGHT.
