Pulse generator of special signal for synchronizing receivers of master-remote system
Abstract
Abstract A CIRCUIT FOR GENERATING A SPECIAL SIGNAL FOR SYNCHRONIZING THE RECEIVERS OF A MASTER-REMOTE SYSTEM OF THE KIND USED FOR THE SUPERVISION AND CONTROL OF APPARATUS FROM A REMOTE LOCATION, AND IN WHICH THE INFORMATION SIGNALS USED FOR SUPERVISION AND CONTROL CONSIST OF TRAINS OF ELECTRICAL PULSES, ALL THE PULSES OF EACH TRAIN BEING OF THE SAME LENGTH. TWO SPECIAL PULSES ARE TRANSMITTED FOR SYNCHRONIZATION JUST PRIOR TO THE START OF EACH TRAIN OF INFORMATION PULSES. THE SPECIAL PULSES ARE OF PREDETERMINED POLARITY, AND ARE EACH ONE AND ONE-HALF TIMES AS LONG AS THE INFORMATION PULSES. THE CIRCUIT USES A COUNTER AND A SERIES OF FLIP-FLOPS AND GATES TO PRODUCE THE DESIRED SYNCHRONIZING SIGNALS, AND ALSO TO DEFINE THE PROPER DURATIONS OF THE INFORMATION PULSES. IN ADDITION, A GATE ARRANGEMENT IS USED TO PRODUCE A SPECIAL START DATA PULSE AT A PREDETERMINED TIME AFTER THE SYNCHRONIZING PULSES ARE COMPLETED.
