Average-responding meter

Claim 1

AN AVERAGE-RESPONDING METER COMPRISING FIRST AND SECOND INPUT TERMINALS FOR RECEIVING AN APPLIED INPUT SIGNAL, A VARIABLE RESISTOR HAVING FIRST AND SECOND TERMINALS AND A SLIDER, A FIRST SWITCH COUPLED TO SAID FIRST INPUT TERMINAL AND THE FIRST TERMINAL OF SAID RESISTOR FOR CONNECTING SAID FIRST INPUT TERMINAL TO THE FIRST TERMINAL OF SAID RESISTOR WHEN ACTUATED, A METER HAVING FIRST AND SECOND TERMINALS, THE SECOND TERMINAL OF SAID RESISTOR BEING COUPLED TO THE SLIDER OF SAID RESISTOR AND ALSO TO THE FIRST TERMINAL OF SAID METER, THE SECOND TERMINAL OF SAID METER BEING CONNECTED TO SAID SECOND INPUT TERMINAL, A CAPACITOR HAVING FIRST AND SECOND TERMINALS, THE FIRST TERMINAL OF SAID CAPACITOR BEING CONNECTED TO THE SLIDER OF SAID RESISTOR, THE SECOND TERMINAL OF SAID CAPACITOR BEING CONNECTED TO SAID SECOND INPUT TERMINAL, A SOURCE OF POTENTIAL, AN INDICATOR HAVING A TERMINAL CONNECTED TO SAID SOURCE OF POTENTIAL, A SECOND SWITCH COUPLED TO SAID OF POTENTIAL, AN INDICATOR HAVING A TERMINAL, CONNECTED TO CATOR FOR CAUSING SAID INDICATOR TO INDICATE WHEN SAID SECOND SWITCH IS ACTUATED, A MOTOR HAVING A TERMINAL CONNECTED TO SAID SOURCE OF POTENTIAL, A THIRD SWITCH COUPLED TO ANOTHER TERMINAL OF SAID MOTOR AND TO SAID SOURCE OF POTENTIAL FOR CAUSING SAID MOTOR TO ROTATE WHEN SAID THIRD SWITCH IS CLOSED, SAID MOTOR BEING MECHANICALLY COUPLED TO SAID SWITCHES AND THE SLIDER OF SAID RESISTOR FOR SUCCESSIVELY ACTUATING SAID FIRST SWITCH WHEN SAID THIRD SWITCH IS CLOSED, MOVING SAID SLIDER TO MAINTAIN THE PRODUCT OF THE RESISTANCE BETWEEN THE FIRST TERMINAL OF SAID RESISTOR AND THE SLIDER OF SAID RESISTOR AND THE CAPACITANCE OF SAID CAPACITOR SUBSTANTIALLY EQUAL TO THE TIME ELAPSED SINCE THE ACTUATION OF SAID FIRST SWITCH, ACTUATING SAID SECOND SWITCH AND OPENING SAID THIRD SWITCH BEFORE THE SLIDER OF SAID RESISTOR REACHES THE SECOND TERMINAL OF SAID RESISTOR.
