Multiple selection system

Claim 1

IN AN ELECTRICAL SWITCHING SYSTEM IN WHICH ANY ONE OF A PLURALITY OF ELECTRICAL SIGNAL GROUPS RECORDED IN ANY ONE OF A PLURALITY OF RECORDED SIGNAL SOURCES MAY BE DIRECTED TO ANY COMBINATION OF ONE OR MORE UTILIZATION DEVICES IN ACCORDANCE WITH A PREDETERMINED PROGRAM IN RESPECT TO PRIORITY AND DESTINATION, THE MULTIPLE SELECTION SYSTEM WHICH WILL PRODUCE FOR EACH UTILIZATION DEVICE AN ELECTRICAL SIGNAL WHICH WILL ENABLE THAT UTILIZATION DEVICE TO BE CONNECTED TO THE RECORDED SIGNAL SOURCES IN WHICH ARE RECORDED ELECTRICAL SIGNAL GROUPS DESTINED FOR THAT UTILIZATION DEVICE IN DESCENDING ORDER OF PRECEDENCE COMPRISING, CYCLIC MEMORY MEANS DIVIDED INTO A PLURALITY OF SECTOR DIVISIONS, EACH CORRESPONDING TO AN INDIVIDUAL RECORDED SIGNAL SOURCE, A PLURALITY OF SLOT DIVISIONS, EACH CORRESPONDING TO AT LEAST ONE RESPECTIVE UTILIZATION DEVICE AND A PLURALITY OF PRIORITY TRACK DIVISIONS CORRESPONDING TO RESPECTIVE PRIORITY RATINGS IN SUCH A MANNER THAT THE INTERSECTION OF THE PRIORITY TRACK AND SLOT DIVISIONS WITHIN EACH SECTOR DIVISION FORM A PLURALITY OF SUBDIVISION CELLS EACH ADAPTED TO STORE A SINGLE DATA SIGNAL WHEREBY A DATA SIGNAL PRESENT WITHIN ANY CELL DENOTES THE PRESENCE OF A SIGNAL GROUP IN THE RECORDED SIGNAL SOURCE TO WHICH THE SECTOR DIVISION CONTAINING THAT CELL CORRESPONDS TO A DESTINATION AND PRIORITY AS DETERMINED BY THE PRIORITY TRACK AND SLOT DIVISIONS WHICH INTERSECT TO FORM THAT CELL; SAID CYCLIC MEMORY MEANS HAVING A SECTOR TRACK DIVISION WITH A SECTOR SIGNAL RECORDED FOR THE BEGINNING OF EACH SECTOR DIVISION AND A REFERENCE TRACK DIVISION WITH A REFERENCE SIGNAL RECORDED FOR THE BEGINNING OF THE FIRST SECTOR DIVISION THEREON; A SOURCE OF CLOCK PULSES SYNCHRONIZED WITH SAID CYCLIC MEMORY MEANS, A SIGNAL SENSITIVE MEANS FOR EACH TRACK DIVISION IN OPERATIVE RELATIONSHIP WITH EACH OF SAID SLOT DIVISIONS ONCE DURING EACH CYCLE OF SAID MEMORY MEANS, FIRST CIRCUIT MEANS COUPLED TO SAID SOURCE OF CLOCK PULSES AND RESPONSIVE TO SAID CLOCK SIGNALS FOR PRODUCING A READ SIGNAL ONLY WHEN THE SLOT DIVISION TO WHICH THAT UTILIZATION DEVICE CORRESPONDS IS IN OPERATIVE RELATIONSHIP WITH SAID SIGNAL SENSITIVE MEANS; SECOND CIRCUIT MEANS RESPONSIVE TO SAID SECTOR SIGNALS FOR PRODUCING SIGNAL REPRESENTATIONS OF EACH SECTOR DIVISION DURING THE TIME THE SLOT DIVISIONS INCLUDED THEREIN ARE SUCCESSIVELY IN OPERATIVE RELATIONSHIP WITH SAID SIGNAL SENSITIVE MEANS; THIRD CIRCUIT MEANS FOR PRODUCING A SELECTION SIGNAL UPON THE RECEIPT OF A READ SIGNAL AND A FIRST DATA SIGNAL PROVIDED THAT NO DATA SIGNAL IS PRESENT IN A PRIORITY TRACK DIVISION HAVING A HIGHER PRIORITY RATING THAN THE RATING OF THE TRACK DIVISION CONTAINING SAID FIRST DATA SIGNAL, AND WHICH IS CONTAINED IN A SLOT ASSIGNED TO THE UTILIZATION DEVICE CORRESPONDING TO SAID THIRD CIRCUIT MEANS, STORAGE CIRCUIT MEANS COUPLED TO SAID SECOND CIRCUIT MEANS FOR STORING THE SIGNAL REPRESENTATIONS PRODUCED BY SAID SECOND CIRCUIT MEANS, AND SHIFT CIRCUIT MEANS INTERCONNECTED BETWEEN SAID SECOND CIRCUIT MEANS AND SAID STORAGE CIRCUIT MEANS FOR EFFECTING THE TRANSFER OF THE SIGNAL REPRESENTATIONS PRODUCED BY SAID SECOND CIRCUIT MEANS TO SAID STORAGE CIRCUIT MEANS IN RESPONSE TO THE APPLICATION THERETO OF SAID SELECTION SIGNAL.
