Apparatus for electronic programming of three channel machine tool automatic controltape

Claim 1

AN APPARATUS FOR CONTROLLING THE OPERATION OF A MACHINE TOOL HAVING A BED, IN THE REPRODUCTION OF FACSIMILES OF A PREVIOUSLY MACHINED PROTOTYPE, IN RESPONSE TO SIGNALS RECORDED ON A RECORD MEDIUM, IN COMBINATION: A PLURALITY OF SPEED-CONTROLLABLE SERVOMOTORS FOR MOVING SAID BED ON RESPECTIVE AXES; A CORRESPONDING PLURALITY OF POSITION SIGNAL GENERATING FEED-BACK TRANSDUCERS DRIVEN BY MOVEMENTS OF SAID BED ON RESPECTIVE AXES; A PLURALITY OF DIRECTION SIGNAL GENERATING DEVICES EACH RESPONSIVE TO DIRECTIONAL CHANGE OF MOVEMENT OF SAID BED ON A RESPECTIVE AXIS, ARRANGED TO IMPART A DIRECTIONAL CHARACTERISTIC TO EACH POSITION INDICATING SIGNAL GENERATED BY A RESPECTIVE TRANSDUCER; A PLURALITY OF FLIPFLOP NETWORKS, TRIGGERED BY SAID DIRECTIONAL CHARACTERISTICS, FOR DIRECTIONALLY TRANSMITTING REPRODUCED SIGNALS; MEANS FOR REPRODUCING STORED SIGNALS; RESPECTIVE STORING INTEGRATORS EACH RESPONSIVE TO A RESPECTIVE SERIES OF REPRODUCED SIGNALS TRANSMITTED THROUGH A RESPECTIVE FLIP-FLOP NETWORK TO DEVELOP AND STORE A STAIRCASE VOLTAGE INDICATING BOTH POSITION AND DIRECTION; MEANS RESPONDING TO SAID STAIRCASE VOLTAGE AND TO BACK-FEED SIGNALS DELIVERED FROM SAID TRANSDUCERS, DIRECTLY TO CONTROL THE TRANSMISSION FROM THE POWER SOURCE OF POWER SIGNALS FOR DIRECTLY OPERATING SAID SERVOMOTORS DIRECTIONALLY IN A FACSIMILE REPRODUCING OPERATION; AND MEANS FOR FEEDING BACK TO SAID INTEGRATOR, NEW DIRECTIONAL AND POSITION INDICATING SIGNALS GENERATED BY A RESPECTIVE TRANSDUCER, FOR REDUCING SAID STAIRCASE VOLTAGE IN PROPORTION TO THE EXTENT OF BED MOVEMENT, WHEREBY THE SPEED OF RESPONSE OF SAID BED TO THE STORED SIGNALS IS INDEPENDENT OF THE SPEED OF RECEPTION OF REPRODUCED SIGNALS.
