Velocity meter with digital readout

Claim 1

IN COMBINATION: A MECHANICAL MEMBER, PIVOTED FOR ROTATION; DETECTING MEANS FOR DETECTING THE DEFLECTION OF SAID MECHANICAL MEMBER FROM A PREDETERMINED NEUTRAL POSITION AND FOR GENERATING A SIGNAL WHICH IS A MEASURE OF SAID DEFLECTION; MAGNETIC FORCE GENERATING MEANS, CONNECTED TO APPLY FORCE TO SAID MECHANICAL MEMBER, INCLUDING TWO ELECTROMAGNET MEANS AND AN ADDITIONAL MAGNET MEANS; CAPACITIVE MEANS, CONNECTED IN SERIES WITH A FIRST ONE OF SAID ELECTROMAGNET MEANS; PULSE GENERATING MEANS ADAPTED TO GENERATE CURRENT PULSES OF EQUAL CHARGE CONTENT HAVING A DIRECTION CONTROLLED BY THE POLARITY OF VOLTAGE ACROSS SAID CAPACITIVE MEANS, AND ADAPTED TO GENERATE DIGITAL INFORMATION PULSES AT TWO SEPARATE TERMINALS IN RESPONSE TO THE POLARITY OF SAID CAPACITIVE VOLTAGE, DIGITAL INFORMATION PULSES APPEARING ON A FIRST SAID TERMINAL WHEN THE VOLTAGE ACROSS SAID CAPACITIVE MEANS HAS A FIRST POLARITY AND DIGITAL INFORMATION PULSES APPEARING ON A SECOND SAID TERMINAL WHEN THE VOLTAGE ACROSS SAID CAPACITIVE MEANS HAS A SECOND POLARITY, THE CURRENT PULSES BEING DRIVEN THROUGH THE SECOND SAID ELETROMAGNET MEANS; AMPLIFYING MEANS CONNECTED TO CHARGE AND DISCHARGE SAID CAPACITIVE MEANS AND TO DRIVE CURRENT THROUGH SAID FIRST ELECTROMAGNET MEANS IN RESPONSE BOTH TO SIGNALS FROM SAID DETECTION MEANS AND TO THE CURRENT PULSES THROUGH SAID SECOND ELECTROMAGNET MEANS TO CAUSE SAID MECHANICAL MEMBER TO RECEIVE A SMOOTH RESTORING TORQUE AND TO CAUSE THE DIFFERENCE BETWEEN SAID DIGITAL INFORMATION PULSES APPEARING AT SAID TWO TERMINALS TO BE A MEASURE OF THE TIMED INTEGRAL OF FORCE APPLIED TO SAID MECHANICAL MEMBER.
