A SYSTEM FOR MEASURING TIME INTERVALS BETWEEN CONTROL PULSES, COMPRISING PULSE MEANS FOR GENERATING TIMING PULSES, CONTROL MEANS FOR GENERATING CONTROL PULSES, A PULSE DELAY UNIT, A FIRST GATE UNIT FOR OPENING AND CLOSING WHEN RECEIVING SUCCESSIVE CONTROL PULSES AND FOR PASSING DELAYED TIMING PULSES THERETHROUGH WHEN OPEN AND WHEN RECEIVING DELAYED TIMING PULSES, A SECOND GATE UNIT FOR ALTERNATELY CLOSING AND OPENING WHEN RECEIVING SUCCESSIVE CONTROL PULSES, SAID SECOND GATE UNIT OPENING AND CLOSING WHEN SAID FIRST GATE UNIT CLOSES AND OPENS, RESPECTIVELY, AND FOR PASSING DELAYED TIMING PULSES THERETHROUGH WHEN SAID SECOND GATE IS OPEN AND IS RECEIVING DELAYED TIMING PULSES. AND AND GATE FOR PASSING TIMING PULSES THROUGH SAID AND GATE WHEN RECEIVING BOTH TIMING PULSES AND A SQUARE WAVE SIGNAL, MEANS RESPONSIVE TO TIMING PULSES PASSING THROUGH SAID AND GATE FOR COUNTING SAID TIMING PULSES PASSING THROUGH SAID AND GATE, A FIRST CONDUCTOR MEANS CONNECTED FROM SAID PULSE MEANS TO SAID PULSE DELAY UNIT AND TO SAID AND GATE FOR PASSING SAID TIMING PULSES TO SAID PULSE DELAY UNIT AND TO SAID AND GATE, A SECOND CONDUCTOR MEANS CONNECTED FROM SAID PULSE DELAY UNIT TO SAID FIRST GATE UNIT AND TO SAID SECOND GATE UNIT FOR PASSING DELAYED TIMING PULSES TO SAID FIRST AND SECOND GATE UNITS, A THIRD CONDUCTOR MEANS CONNECTED FROM SAID CONTROL MEANS TO SAID FIRST GATE UNIT AND TO SAID SECOND GATE UNIT FOR PASSING CONTROL PULSES TO SAID FIRST AND SECOND GATE UNITS, A BISTABLE MULTIVIBRATOR FOR GENERATING A SUBSTANTIALLY SQUARE WAVE SIGNAL WHEN RECEIVING DELAYED TIMING PULSES FROM ONE OF SAID GATE UNITS, A FOURTH CONDUCTOR MEANS CONNECTED FROM SAID FIRST GATE UNIT TO SAID MULTIVIBRATOR FOR PASSING DELAYED TIMING PULSES FROM SAID FIRST GATE UNIT TO SAID MULTIVIBRATOR, A FIFTH CONDUCTOR MEANS CONNECTED FROM SAID SECOND GATE UNIT TO SAID MULTIVIBRATOR FOR PASSING DELAYED TIMING PULSES FROM SAID SECOND GATE UNIT TO SAID MULTIVIBRATOR, AND A SIXTH CONDUCTOR MEANS CONNECTED FROM SAID MULTIVIBRATOR TO SAID AND GATE FOR PASSING SAID SQUARE WAVE SIGNAL TO SAID AND GATE.
