Plural motor torque control for tape transport mechanism

Claim 1

A TAPE TRANSPORT MECHANISM FOR TRANSFERRING A TAPE BETWEEN FIRST AND SECOND TAPE REELS, A FIRST REVERSIBLE MOTOR FOR DRIVING THE FIRST REEL IN EITHER OF TWO OPPOSITE DIRECTIONS, A SECOND REVERSIBLE MOTOR FOR DRIVING THE SECOND REEL IN EITHER OF TWO OPPOSITE DIRECTIONS, FIRST MEANS NORMALLY COUPLED TO SAID FIRST AND SECOND MOTORS FOR ENERGIZING SAID FIRST AND SECOND MOTORS TO DRIVE THE FIRST AND THE SECOND REELS IN OPPOSITE DIRECTIONS WHEREBY TENSION IS MAINTAINED ON THE TAPE, SECOND MEANS COUPLED TO SAID FIRST AND TO SAID SECOND MOTORS FOR ENERGIZING SAID FIRST AND SECOND MOTORS TO DRIVE THE FIRST AND THE SECOND REELS AT TORQUES DIFFERENT FROM EACH OTHER BUT IN THE SAME DIRECTION FOR AN ACCELERATION OF THE TAPE TO AN OPERATING SPEED, SWITCHING MEANS COUPLED TO THE FIRST AND SECOND ENERGIZING MEANS FOR DISCONNECTING SAID FIRST ENERGIZING MEANS FROM SAID MOTORS AND FOR COUPLING SAID SECOND ENERGIZING MEANS TO SAID MOTOR TO OBTAIN AN ACCELERATION OF THE TAPE, MEANS COUPLED TO SAID SWITCHING MEANS FOR REVERSING THE POLARITY OF THE ENERGIZING APPLIED BY SAID FIRST AND SECOND ENERGIZING MEANS TO SAID FIRST AND SAID SECOND MOTORS TO BRING THE TAPE TO A STANDSTILL AND INITIATE THE MOVEMENT OF THE TAPE IN THE OPPOSITE DIRECTION, AND MEANS CONTROLLED BY SAID REVERSING MEANS WHEN THE TAPE MOVEMENT IS INITIATED IN THE OPPOSITE DIRECTION FOR DISCONNECTING SAID SECOND ENERGIZING MEANS FROM SAID MOTORS AND RECONNECTING SAID FIRST ENERGIZING MEANS TO SAID MOTORS TO RESTABLISH TENSION ON THE TAPE AT STANDSTILL.
