Remote function control by discrete pulse patterns

Claim 1

A SYSTEM FOR REMOTELY CONTROLLING FROM A CONTROL STATION A FUNCTION AT A REMOTE STATION BETWEEN ITS FIRST AND SECOND CONDITION, COMPRISING IN COMBINATION; (A) A LINE CIRCUIT MEANS CONNECTING SAID CONTROL AND REMOTE STATION AND HAVING A FIRST AND A SECONND CONDITION, SAID LINE CIRCUIT BEING NORMALLY IN IT FIRST CONDITION, (B) A FIRST CONTROL MEANS AT SAID CONTROL STATION FOR CONTROLLING SAID LINE CIRCUIT MEANS TO ITS SECOND CONDITION FOR A SELECTED PERIOD OF TIME TO INITIATE A CONTROL TRANSMISSION, (C) A SECOND CONTROL MEANS AT SAID CONTROL STATION HAVING CONNECTIONS FOR AT TIMES CONTROLLING SAID LINE CIRCUIT MEANS TO A BRIEF PERIOD OF SECOND CONDITION A PRESELECTED TIME INTERVAL AFTER THE TERMINATION OF THE SECOND CONDITION PERIOD CONTROLLED BY SAID FIRST MEANS IN ACCORDANCE WITH THE DESIRED CONDITION OF SAID FUNCTION, (D) A FIRST MONITOR MEANS AT SAID REMOTE STATION CONTROLLED BY SAID LINE CIRCUIT MEANS FOR DETECTING THE END OF THE SECOND CONDITION PERIOD CONTROLLED BY SAID FIRST CONTROL MEANS ONLY DURING A FIRST PREDETERMINED TIME INTERVAL AFTER THE BEGINNING OF THAT SECOND CONDITION PERIOD, (E) A SECOND MONITOR MEANS AT SAID REMOTE STATION CONTROLLED JOINTLY BY SAID LINE CIRCUIT MEANS AND SAID FIRST MONITOR MEANS FOR DETECTING SAID BRIEF PERIOD OF LINE CIRCUIT SECOND CONDITION ONLY DURING ANOTHER PRESELECTED TIME INTERVAL AFTER THE BEGINNING OF THE FIRST SECOND CONDITION PERIOD AND ONLY IF SAID FIRST MONITOR MEANS HAS DETECTED THE END OF THAT FIRST SECOND CONDITION PERIOD DURING SAID FIRST PREDETERMINED TIME INTERVAL, (F) SAID SECOND MONITOR MEANS HAVING CONNECTIONS FOR OPERATING SAID FUNCTION TO ITS SECOND CONDITION WHEN SAID BRIEF SECOND CONDITION PERIOD OF SAID LINE CIRCUIT MEANS IS DETECTED DURING THE PROPER INTERVAL AND TO ITS FIRST CONDITION WHEN ONLY SAID FIRST SECOND CONDITION PERIOD OF SAID LINE CIRCUIT MEANS IS DETECTED.

Claim 2

A SYSTEM FOR REMOTELY CONTROLLING FROM A CONTROL STATION A FUNCTION AT A REMOTE STATION BETWEEN ITS FIRST AND SECOND CONDITION, COMPRISING IN COMBINATION; (A) A LINE CIRCUIT MEANS CONNECTING SAID CONTROL AND REMOTE STATION AND HAVING A FIRST AND A SECONND CONDITION, SAID LINE CIRCUIT BEING NORMALLY IN IT FIRST CONDITION, (B) A FIRST CONTROL MEANS AT SAID CONTROL STATION FOR CONTROLLING SAID LINE CIRCUIT MEANS TO ITS SECOND CONDITION FOR A SELECTED PERIOD OF TIME TO INITIATE A CONTROL TRANSMISSION, (C) A SECOND CONTROL MEANS AT SAID CONTROL STATION HAVING CONNECTIONS FOR AT TIMES CONTROLLING SAID LINE CIRCUIT MEANS TO A BRIEF PERIOD OF SECOND CONDITION A PRESELECTED TIME INTERVAL AFTER THE TERMINATION OF THE SECOND CONDITION PERIOD CONTROLLED BY SAID FIRST MEANS IN ACCORDANCE WITH THE DESIRED CONDITION OF SAID FUNCTION, (D) A FIRST MONITOR MEANS AT SAID REMOTE STATION CONTROLLED BY SAID LINE CIRCUIT MEANS FOR DETECTING THE END OF THE SECOND CONDITION PERIOD CONTROLLED BY SAID FIRST CONTROL MEANS ONLY DURING A FIRST PREDETERMINED TIME INTERVAL AFTER THE BEGINNING OF THAT SECOND CONDITION PERIOD, (E) A SECOND MONITOR MEANS AT SAID REMOTE STATION CONTROLLED JOINTLY BY SAID LINE CIRCUIT MEANS AND SAID FIRST MONITOR MEANS FOR DETECTING SAID BRIEF PERIOD OF LINE CIRCUIT SECOND CONDITION ONLY DURING ANOTHER PRESELECTED TIME INTERVAL AFTER THE BEGINNING OF THE FIRST SECOND CONDITION PERIOD AND ONLY IF SAID FIRST MONITOR MEANS HAS DETECTED THE END OF THAT FIRST SECOND CONDITION PERIOD DURING SAID FIRST PREDETERMINED TIME INTERVAL, (F) SAID SECOND MONITOR MEANS HAVING CONNECTIONS FOR OPERATING SAID FUNCTION TO ITS SECOND CONDITION WHEN SAID BRIEF SECOND CONDITION PERIOD OF SAID LINE CIRCUIT MEANS IS DETECTED DURING THE PROPER INTERVAL AND TO ITS FIRST CONDITION WHEN ONLY SAID FIRST SECOND CONDITION PERIOD OF SAID LINE CIRCUIT MEANS IS DETECTED.
