Pattern controlled programming mechanism

Claim 1

IN A CYCLICALLY-OPERABLE MACHINE, A PATTERN CONTROLLED PROGRAMMING MECHANISM COMPRISING A LIGHT SOURCE; A MOVABLE PATTERNED CONTROL ELEMENT; A LIGHT-SENSITIVE ELECTRICAL DEVICE, ARRANGED TO RECEIVE LIGHT FROM SAID SOURCE UNDER THE CONTROL OF SAID ELEMENT, MEANS FOR MOVING SAID ELEMENT BETWEEN SAID LIGHT SOURCE AND SAID DEVICE, MEANS CAPABLE OF GENERATING ELECTRICAL PULSES IN SYNCHRONISM WITH THE CYCLICAL OPERATION OF SAID MACHINE; A DIFFERENTIAL AMPLIFIER, INCLUDING A PAIR OF ALTERNATIVELY-OPERABLE AMPLIFYING MEANS, OF WHICH ONE IS OPERABLE WHEN SAID ELEMENT PERMITS MAXIMUM TRANSMISSION OF LIGHT BETWEEN SAID SOURCE AND SAID DEVICE AND OF WHICH THE OTHER IS OPERABLE WHEN SAID ELEMENT PERMITS MINIMUM TRANSMISSION OF LIGHT BETWEEN SAID SOURCE AND SAID DEVICE; A PAIR OF AND GATES EACH HAVING INPUT AND OUTPUT CONNECTIONS, THE INPUT CONNECTIONS OF ONE OF SAID GATES BEING CONNECTED TO SAID PULSE GENERATING MEANS AND TO ONE OF SAID AMPLIFYING MEANS AND THE INPUT CONNECTIONS OF THE OTHER OF SAID GATES BEING CONNECTED TO SAID PULSE GENERATING MEANS AND TO THE OTHER OF SAID AMPLYFYING MEANS; A BISTABLE CIRCUIT CONNECTED TO SAID OUTPUT CONNECTIONS OF EACH OF SAID AND GATES, THEREBY TO BE OPERATED ALTERNATIVELY THROUGH SAID GATES IN ACCORDANCE WITH SIMULTANEOUS RECEPTION THEREBY OF A PULSE FROM SAID GENERATOR AND A SIGNAL FROM SAID DIFFERENTIAL AMPLIFIER; A DRIVING AMPLIFIER CONNECTED TO SAID BI-STABLE CIRCUIT FOR OPERATION THEREBY; AN OUTPUT RELAY INCLUDING A SOLENOID CONNECTED TO SAID DRIVING AMPLIFIER FOR OPERATION THEREBY, AND A SOURCE OF ELECTRICAL POWER FOR SAID DIFFERENTIAL AMPLIFIER, AND GATES, BI-STABLE CIRCUIT, DRIVING AMPLIFIER AND SOLENOID.
