System for detecting perforation errors in synchronous printing telegraphic apparatus

Claim 1

AN APPARATUS FOR DETECTING ERRORS IN THE GROUPS OF CODE PERFORATIONS MADE IN A TAPE IN A SYNCHRONOUS PRINTING TELEGRAPHIC APPARATUS, SAID ERROR DETECTING APPARATUS COMPRISING A PHOTOELECTRIC DEVICE HAVING A ROTATING DISK AND A LIGHT ADAPTED TO BE POSITIONED ON OPPOSITE SIDES OF THE TRANSMISSION TAPE OF THE TELEGRAPHIC APPARATUS FOR SEQUENTIALLY SCANNING THE NUMBER AND POSITION OF LIGHT BEAMS PASSING THE PUNCHED HOLE POSITIONS IN WHICH THE PERFORATIONS OF A GROUP OF CODE PERFORATIONS ARE LOCATED ON THE TRANSMISSION TAPE, SAID PHOTOELECTRIC DEVICE ALSO HAVING MEANS FOR CONVERTING THE SERIES OF LIGHT PULSES PASSED THROUGH A GROUP OF CODE PERFORATIONS IN THE TRANSMISSION TAPE AND THROUGH SAID ROTATING DISK INTO A SERIES OF ELECTRIC SIGNALS, MEANS COUPLED TO SAID PHOTOELECTRIC DEVICE FOR TRANSMITTING SAID SERIES OF ELECTRIC SIGNALS, A RECEIVING SET RECEIVING SAID SERIES OF ELECTRIC SIGNALS, A PUNCHING MECHANISM COUPLED TO SAID RECEIVING SET AND ACTUATED BY SAID RECEIVING SET FOR PUNCHING A RECEIVING TAPE WITH A GROUP OF PERFORATIONS CORRESPONDING TO THE GROUP OF PERFORATIONS ON THE TRANSMISSION TAPE, A SIGNAL PRODUCING DEVICE COUPLED TO SAID PRINTING MECHANISM FOR PRODUCING A SERIES OF SIGNALS FOR THE ACTIONS OF THE PUNCHING DEVICE IN PUNCHING THE GROUP OF PERFORATIONS IN THE RECEIVING TAPE, A MEMORIZING DEVICE COUPLED TO SAID SIGNAL PRODUCING DEVICE FOR RECEIVING AND MEMORIZING THE SERIES OF SIGNALS PRODUCED IN RESPONSE TO THE GROUP OF PERFORATIONS PUNCHED IN SAID RECEIVING TAPE, A COMPARING DEVICE COUPLED TO SAID PHOTOELECTRIC DEVICE AND TO SAID MEMORY DEVICE FOR COMPARING THE NUMBER AND POSITION OF THE LIGHT BEAMS PASSED THROUGH THE GROUP OF PERFORATIONS IN THE TRANSMISSION TAPE WITH THE SERIES OF SIGNALS MEMORIZED BY SAID MEMORIZING DEVICE AND PRODUCING A SIGNAL WHEN THERE IS A DIFFERENCE BETWEEN THE SERIES AND THE NUMBER AND POSITION OF THE LIGHT BEAMS, A CLUTCH CONTROL MEANS COUPLED TO SAID PHOTOELECTRIC DEVICE THROUGH WHICH SAID PHOTOELECTRIC DEVICE IS DRIVEN, SAID CLUTCH CONTROL MEANS BEING COUPLED TO SAID COMPARING DEVICE FOR BEING ACTUATED TO BE DISENGAGED WHEN A SIGNAL IS PRODUCED BY SAID COMPARING DEVICE, AND AN ERASING DEVICE COUPLED TO SAID MEMORY DEVICE FOR PERIODICALLY ERASING THE SERIES OF SIGNALS MEMORIZED BY SAID MEMORY DEVICE.

Claim 2

AN APPARATUS FOR DETECTING ERRORS IN THE GROUPS OF CODE PERFORATIONS MADE IN A TAPE IN A SYNCHRONOUS PRINTING TELEGRAPHIC APPARATUS, SAID ERROR DETECTING APPARATUS COMPRISING A PHOTOELECTRIC DEVICE HAVING A ROTATING DISK AND A LIGHT ADAPTED TO BE POSITIONED ON OPPOSITE SIDES OF THE TRANSMISSION TAPE OF THE TELEGRAPHIC APPARATUS FOR SEQUENTIALLY SCANNING THE NUMBER AND POSITION OF LIGHT BEAMS PASSING THE PUNCHED HOLE POSITIONS IN WHICH THE PERFORATIONS OF A GROUP OF CODE PERFORATIONS ARE LOCATED ON THE TRANSMISSION TAPE, SAID PHOTOELECTRIC DEVICE ALSO HAVING MEANS FOR CONVERTING THE SERIES OF LIGHT PULSES PASSED THROUGH A GROUP OF CODE PERFORATIONS IN THE TRANSMISSION TAPE AND THROUGH SAID ROTATING DISK INTO A SERIES OF ELECTRIC SIGNALS, MEANS COUPLED TO SAID PHOTOELECTRIC DEVICE FOR TRANSMITTING SAID SERIES OF ELECTRIC SIGNALS, A RECEIVING SET RECEIVING SAID SERIES OF ELECTRIC SIGNALS, A PUNCHING MECHANISM COUPLED TO SAID RECEIVING SET AND ACTUATED BY SAID RECEIVING SET FOR PUNCHING A RECEIVING TAPE WITH A GROUP OF PERFORATIONS CORRESPONDING TO THE GROUP OF PERFORATIONS ON THE TRANSMISSION TAPE, A SIGNAL PRODUCING DEVICE COUPLED TO SAID PRINTING MECHANISM FOR PRODUCING A SERIES OF SIGNALS FOR THE ACTIONS OF THE PUNCHING DEVICE IN PUNCHING THE GROUP OF PERFORATIONS IN THE RECEIVING TAPE, A MEMORIZING DEVICE COUPLED TO SAID SIGNAL PRODUCING DEVICE FOR RECEIVING AND MEMORIZING THE SERIES OF SIGNALS PRODUCED IN RESPONSE TO THE GROUP OF PERFORATIONS PUNCHED IN SAID RECEIVING TAPE, A COMPARING DEVICE COUPLED TO SAID PHOTOELECTRIC DEVICE AND TO SAID MEMORY DEVICE FOR COMPARING THE NUMBER AND POSITION OF THE LIGHT BEAMS PASSED THROUGH THE GROUP OF PERFORATIONS IN THE TRANSMISSION TAPE WITH THE SERIES OF SIGNALS MEMORIZED BY SAID MEMORIZING DEVICE AND PRODUCING A SIGNAL WHEN THERE IS A DIFFERENCE BETWEEN THE SERIES AND THE NUMBER AND POSITION OF THE LIGHT BEAMS, A CLUTCH CONTROL MEANS COUPLED TO SAID PHOTOELECTRIC DEVICE THROUGH WHICH SAID PHOTOELECTRIC DEVICE IS DRIVEN, SAID CLUTCH CONTROL MEANS BEING COUPLED TO SAID COMPARING DEVICE FOR BEING ACTUATED TO BE DISENGAGED WHEN A SIGNAL IS PRODUCED BY SAID COMPARING DEVICE, AND AN ERASING DEVICE COUPLED TO SAID MEMORY DEVICE FOR PERIODICALLY ERASING THE SERIES OF SIGNALS MEMORIZED BY SAID MEMORY DEVICE.
