Work position programming and recording system using symbols on a transparent medium

Claim 1

A SYSTEM FOR POSITIONING A WORK IN ACCORDANCE WITH A GIVEN PROGRAM COMPRISING, IN COMBINATION: SERVO MOTOR MEANS FOR MOVING SAID WORK IN RESPONSE TO A CONTROL SIGNAL AND HOLDING SAID WORK IN A MOVED POSITION WHEN SAID CONTROL SIGNAL IS TERMINATED; PROGRAMMING MEANS CONNECTED TO SAID SERVO MOTOR MEANS FOR PROVIDING SAID CONTROL SIGNAL IN ACCORDANCE WITH A GIVEN PROGRAM; AND A POSITION INDICATING MEANS CONNECTED TO SAID PROGRAMMING MEANS AND RESPONSIVE TO THE POSITION OF SAID WORK TO PROVIDE AN INDICATION THEREOF IN SAID PROGRAMMING MEANS, SAID CONTROL SIGNAL BEING GENERATED WHEN THE INDICATED POSITION IS DIFFERENT FROM THE PROGRAM POSITION AND TERMINATED WHEN THE INDICATED POSITION CORRESPONDS TO THE PROGRAM POSITION, SAID PROGRAMMING MEANS INCLUDING A TRANSPARENT MEDIUM HAVING A SUCCESSION OF GROUPS OF SYMBOLS THEREON, EACH GROUP REPRESENTING A COORDINATE POINT AT WHICH ITS IS DESIRED TO POSITION SAID WORK; A PLURALITY OF LIGHT RESPONSIVE MEANS CORRESPONDING IN NUMBER TO THE NUMBER OF SYMBOLS IN EACH GROUP; MEANS FOR POSITIONING SAID TRANSPARENT MEDIUM WITH RESPECT TO SAID LIGHT RESPONSIVE MEANS SUCH THAT LIGHT PASSES THROUGH SAID MEDIUM TO SAID LIGHT RESPONSIVE TO MEANS AND IS INTERCEPTED BY THE SYMBOLS OF ONE OF SAID GROUPS CORRESPONDING TO A GIVEN COORDINATE POINT, EACH OF SAID LIGHT RESPONSIVE MEANS PROVIDING A SIGNALWHEN ITS POSITION RELATIVE TO ITS ASSOCIATED SYMBOL IS DIFFERENT FROM A GIVEN POSITION AND PROVIDING NO SIGNAL WHEN ITS POSITION CORRESPONDS TO THE POSITION OF ITS ASSOCIATED SYMBOL, SAID CONTROL SIGNAL BEING RESPONSIVE TO SIGNALS FROM SAID LIGHT RESPONSIVE MEANS, SAID POSITION INDICATING MEANS INCLUDING A MOTION TRANSFERRING MEANS FROM SAID SERVO MOTOR TO SAID LIGHT RESPONSIVE MEANS FOR EFFECTING RELATIVE POSITIONING OF SAID LIGHT RESPONSIVE MEANS AND SAID MEDIUM IN ACCORDANCE WITH THE POSITION OF SAID WORK SO THAT WHEN SAID WORK REACHES A POSITION CORRESPONDING TO SAID GIVEN COORDINATE POINT, THE RELATIVE POSITIONS OF SAID LIGHT RESPONSIVE MEANS AND MEDIUM ARE SUCH THAT NO SIGNALS ARE RECEIVED THEREFROM SO THAT SAID WORK IS HELD IN ITS MOVED POSITION UNTIL THE NEXT SUCCESSIVE GROUP OF SYMBOLS IS POSITIONED TO INTERCEPT LIGHT PASSING TO SAID LIGHT RESPONSIVE MEANS.

Claim 2

A SYSTEM FOR POSITIONING A WORK IN ACCORDANCE WITH A GIVEN PROGRAM COMPRISING, IN COMBINATION: SERVO MOTOR MEANS FOR MOVING SAID WORK IN RESPONSE TO A CONTROL SIGNAL AND HOLDING SAID WORK IN A MOVED POSITION WHEN SAID CONTROL SIGNAL IS TERMINATED; PROGRAMMING MEANS CONNECTED TO SAID SERVO MOTOR MEANS FOR PROVIDING SAID CONTROL SIGNAL IN ACCORDANCE WITH A GIVEN PROGRAM; AND A POSITION INDICATING MEANS CONNECTED TO SAID PROGRAMMING MEANS AND RESPONSIVE TO THE POSITION OF SAID WORK TO PROVIDE AN INDICATION THEREOF IN SAID PROGRAMMING MEANS, SAID CONTROL SIGNAL BEING GENERATED WHEN THE INDICATED POSITION IS DIFFERENT FROM THE PROGRAM POSITION AND TERMINATED WHEN THE INDICATED POSITION CORRESPONDS TO THE PROGRAM POSITION, SAID PROGRAMMING MEANS INCLUDING A TRANSPARENT MEDIUM HAVING A SUCCESSION OF GROUPS OF SYMBOLS THEREON, EACH GROUP REPRESENTING A COORDINATE POINT AT WHICH ITS IS DESIRED TO POSITION SAID WORK; A PLURALITY OF LIGHT RESPONSIVE MEANS CORRESPONDING IN NUMBER TO THE NUMBER OF SYMBOLS IN EACH GROUP; MEANS FOR POSITIONING SAID TRANSPARENT MEDIUM WITH RESPECT TO SAID LIGHT RESPONSIVE MEANS SUCH THAT LIGHT PASSES THROUGH SAID MEDIUM TO SAID LIGHT RESPONSIVE TO MEANS AND IS INTERCEPTED BY THE SYMBOLS OF ONE OF SAID GROUPS CORRESPONDING TO A GIVEN COORDINATE POINT, EACH OF SAID LIGHT RESPONSIVE MEANS PROVIDING A SIGNALWHEN ITS POSITION RELATIVE TO ITS ASSOCIATED SYMBOL IS DIFFERENT FROM A GIVEN POSITION AND PROVIDING NO SIGNAL WHEN ITS POSITION CORRESPONDS TO THE POSITION OF ITS ASSOCIATED SYMBOL, SAID CONTROL SIGNAL BEING RESPONSIVE TO SIGNALS FROM SAID LIGHT RESPONSIVE MEANS, SAID POSITION INDICATING MEANS INCLUDING A MOTION TRANSFERRING MEANS FROM SAID SERVO MOTOR TO SAID LIGHT RESPONSIVE MEANS FOR EFFECTING RELATIVE POSITIONING OF SAID LIGHT RESPONSIVE MEANS AND SAID MEDIUM IN ACCORDANCE WITH THE POSITION OF SAID WORK SO THAT WHEN SAID WORK REACHES A POSITION CORRESPONDING TO SAID GIVEN COORDINATE POINT, THE RELATIVE POSITIONS OF SAID LIGHT RESPONSIVE MEANS AND MEDIUM ARE SUCH THAT NO SIGNALS ARE RECEIVED THEREFROM SO THAT SAID WORK IS HELD IN ITS MOVED POSITION UNTIL THE NEXT SUCCESSIVE GROUP OF SYMBOLS IS POSITIONED TO INTERCEPT LIGHT PASSING TO SAID LIGHT RESPONSIVE MEANS.
