Circuit for testing a capacitor for momentary breakdown when a d. c. voltage is applied thereto including means responsive to charging of the capacitor

Claim 1

IN A CIRCUIT FOR TESTING A CAPACITOR FOR MOMENTARY BREAKDOWN WHEN A D.C. VOLTAGE IS APPLIED THERETO AND FOR EFFECTING A REJECTION OF AN UNSATISFACTORY CAPACITOR: A CAPACITOR CHARGING CIRCUIT FOR PLACING A POTENTIAL ACROSS THE CAPACITOR FOR A PREDTEREMINED TIME INTERVAL; CIRCUIT MEANS ASSOCIATED WITH SAID CHARGING CIRCUIT FOR PRODUCING AN ELECTRICAL SIGNAL DURING EACH CHARGING OF THE CAPACITOR SUCH THAT A SINGLE SIGNAL OCCURS FROM AN INITIAL CHARGING OF THE CAPACITOR AND A SECOND SIGNAL OCCURS UPON MOMENTARY BREAKDOWN OF AND A CONSEQUENT RECHARGING OF THE CAPACITOR; A COUNTING CIRCUIT RESPONSIVE TO SAID CIRCUIT MEANS FOR COUNTING THE NUMBER OF SIGNALS PRODUCED BY SAID CIRCUIT MEANS AND FOR INDICATING THE NUMBER OF SIGNALS SO COUNTED; A MEMORY CIRCUIT RESPONSIVE TO SAID COUNTING CIRCUIT FOR RECORDING THE INDICATED NUMBER OF SIGNALS COUNTED BY SAID COUNTING CIRCUIT; AND A CIRCUIT RESPONSIVE TO SAID MEMORY CIRCUIT FOR EFFECTING A REJECTION OF THE CAPACITOR WHENEVER SAID MEMORY CIRCUIT HAS RECORDED IN INDICATION OF A COUNTING OF AT LEAST TWO SIGNALS BY SAID COUNTING CIRCUIT.
