Numerical control pulse distribution system

Claim 1

A NUMERICAL PULSE DISTRIBUTION SYSTEM FOR CAUSING A MILLING MACHINE COMPONENT TO FOLLOW A DETERMINED PATH RELATIVE TO A COORDINATE SYSTEM BY DISTRIBUTING PULSES RECORDED ON A STORAGE MEDIUM IN ACCORDANCE WITH ARCUATE AND LINEAR SEGMENTS OF SAID DETERMINED PATH TO COMPONENTS MOVING SAID MILLING MACHINE COMPONENT ON THE DIRECTIONS OF RESPECTIVE COORDINATE AXES, COMPRISING DIGITAL ACCUMULATOR MEANS HAVING FOR EACH SEGMENT OF SAID DETERMINED PATH AN INITIAL VALUE SET THEREIN CORRESPONDING TO THE INITIAL COORDINATE POSITION OF EACH SEGMENT UPON THE DETERMINED PATH TO BE FOLLOWED, SAID ACCUMULATOR MEANS HAVING AN INPUT AND AN OUTPUT; DIGITAL MULTIPLIER MEANS HAVING AN INPUT CONNECTED AND RESPONSIVE TO SAID ACCUMULATOR MEANS AND HAVING SET THEREIN A VALUE CORRESPONDING TO A FUNCTION OF THE CHANGE IN COORDINATE POSITION BETWEEN SUCCESIVE POINTS ON SAID DETERMINED PATH, SAIF MULTIPLIER MEANS HAVING AN OUTPUT; AND REGISTER MEANS CONNECTING THE OUTPUT OF SAID MULTIPLIER MEANS TO THE INPUT OF SAID ACCUMULATOR MEANS, SAID ACCUMULATOR MEANS ADDING THE OUTPUT OF SAID MULTIPLIER MEANS TO THE VALUE IN SAID ACCUMULATOR MEANS TO THEREBY SET THE SAID ACCUMULATOR MEANS TO A NEW VALUE, SAID ACCUMULATOR MEANS PRODUCING IN ITS OUTPUT AN OUTPUT PULSE WHEN THE CHANGE BETWEEN SUCCESSIVE VALUES IN THE SAID ACCUMULATOR MEANS EXCEEDS A PREDETERMINED VALUE AND PRODUCING NO OUTPUT PULSE WHEN SAID CHANGE IS LESS THAN A PREDETERMINED VALUE THEREBY TO HALT SAID COMPONENTS MOVING SAID MILLING MACHINE COMPONENT AT THE END OF EACH SEGMENT OF SAID DERTIMED PATH.
