Claim 1

IN A DEVICE FOR INDICATING THE POSITION OF A MOVABLE MEMBER, A CODE MEMBER MOVABLE WITH SAID MOVABLE MEMBER AND HAVING A ZONE THEREON INCLUDING ALTERNATE FIRST AND SECOND PORTIONS WHICH RESPECTIVELY TRANSMIT AND PREVENT THE TRANSMISSION OF A RADIANT ENERGY, A SOURCE OF RADIANT ENERGY CONTINUOUSLY APPLYING RADIATION TO SAID ZONE, READING MEANS RESPONSIVE TO RADIATION TRANSMITTED BY THE RADIATION TRANSMITTING PORTIONS OF SAID ZONE FOR PRODUCING AN OUTPUT SIGNAL HAVING ONE MAGNITUDE WHEN RECEIVING MAXIMUM RADIATION FROM ONE ZONE AND A SECONE LEVEL WHEN RECEIVING SUBSTANTIALLY NO RADIATION FROM SAID ZONE, SAID ZONE ALTERNATELY CAUSING SAID RADIATION TO BE TRANSMITTED TO SAID BLOCKED FROMSAID READING MEANS ON MOVEMENT OF SAID CODE MEMBER WITH SAID MOVABLE MEMBER AND SAID OUTPUT SIGNAL REQUIRING A FINITE MOVEMENT OF THE CODE MEMBER AT THE JUNCTION LINE BETWEEN ADJACENT ONES OF SAID FIRST AND SECOND PORTINS TO VARY SAID OUTPUT SIGNAL BETWEEN ITS TWO EXTREME MAGNITUDES CORRESPONDING RESPECTIVELY TO MAXIMUM RADIATION AND SUBSTANTIALLY NO RADIATION FROM SAID ZONE, AND CURRENT RESPONDIVE CIRCUIT MEANS RESPONSIVE TO SAID OUTPUT SIGNAL PRODUCED BY SAID READING MEANS AND SWITCHED BETWEN TWO STATES SUBSTANTIALLY INSTANTANEOUSLY IN RESPONSE TO SAID OUTPUT SIGNAL BEING INCREASED AND DECREASED TO A CORRESPONDING ONE OF FIRST AND SECOND PRESELECTED MAGNITUDES BETWEEN SAID EXTREME MAGNITUDES AS THE CODE MEMBER IS MOVED TO PROVIDE A SQUARE WAVE OUTPUT, SAID CIRCUIT MEANS COMPRISING A FIRST TRANSISTOR HAVING AN INPUT CIRCUIT TO WHICH SAID OUTPUT SIGNAL IS APPLIED AND AN OUTPUT CIRCUIT, SAID FIRST TRANSISTOR BEING NONCONDUCTIVE AT ONE OF SAID EXTREME MAGNITUDES FOR SAID OUTPUT SIGNAL AND BEING RENDERED CONDUCTIVE AS SAID OUTPUT SIGNAL MOVES TO SAID FIRST PRESELECTED MAGNITUDE, A SECOND TRANSISTOR HAVING AN INPUT CIRCUIT AND AN OUTPUT CIRCUIT, MEANS CONNECTING THE OUTPUT CIRCUIT OF SAID FIRST TRANSISTOR TO THE INPUT CIRCUIT OF SAID SECOND TRANSISTOR TO CONTROL SAID SECOND TRANSISTOR TO PRODUCE SAID SQUARE WAVE OUTPUT AT THE OUTPUT CIRCUIT FOR SAID SECOND TRANSISTOR WHEN SAID FIRST TRANSISTOR BECOMES CONDUCTIVE AND NONCONDUCTIVE, AND REGENERATE CIRCUIT MEANS CONNECTING THE OUTPUT CIRCUIT OF SAID SECOND TRANSISTOR TO THE INPUT OF SAID FIRST TRANSISTOR TO CAUSE SAID FIRST TRANSISTOR TO SWITCH RAPIDLY WHEN SAID OUTPUT SIGNAL REACHES THE CORRESPONDING ONE OF SAID FIRST PRESELECTED MAGNITUDES AND SAID SECOND PRESELECTED MAGNITUDE AS SAID OUTPUT SIGNAL IS INCREASING AND DECREASING BETWEEN ITS EXTREMES.
