Adding system for binary coded excess three numbers

Claim 1

AN ARRAGEMENT FOR PARALLEL ADDING MULTI-DIGIT BINARY CODED NUMBERS REPRESENTING ONE-DIGIT DECIMAL NUMBERS IN TERMS OF AN EXCESS-THREE CODE COMPRISING, IN COMBINATION, ELECTRONIC STORAGE MEANS INCLUDING A SERIES OF FLIPFLOP STAGES RESPECTIVELY ASSIGNED TO THE BINARY DIGIT POSITIONS OF MULTI-DIGIT NUMBERS ACCORDING TO AN EXCESS-THREE BINARY CODE; A PLURALITY OF INPUT MEANS RESPECTIVELY ASSOCIATED WITH SAID FLIP-FLOP STAGES FOR APPLYING SEQUENTIALLY IN PARALLEL TO SAID FLIP-FLOP STAGES, RESPECTIVELY, ELECTRICAL INPUT PULSES RESPECTIVELY REPRESENTING BINARY DIGITS OF MULTI-DIGIT BINARY NUMBERS RESPECTIVELY REPRESENTING THE DECIMAL NUMBERS TO BE ADDED, EACH OF SAID INPUT MEANS COMPRISING AN "OR" CIRCUIT MEANS HAVING THREE INPUTS FOR RECEIVING INPUT, CARRY AND CORRECTION IMPULSES, RESPECTIVELY, AND ONE OUTPUT CONNECTED TO THE INPUT OF THE RESPECTIVELY ASSOCIATED FLIP-FLOP STAGE; A PLURALITY OF BINARY CARRY TRANSMITTING MEANS RESPECTIVELY ARRANGED BETWEEN EACH OF SAID FLIP-FLOP STAGES WHICH IS ASSIGNED TO A BINARY OF THAT OF THE FLIP-FLOP STAGES WHICH IS ASSIGNED TO A BINARY DIGIT POSITION OF RESPECTIVELY NEXT HIGHER SIGNIFICANCE FOR APPLYING A TRANSFER REPRESENTING PULSE THERETO, AND INCLUDING DELAY MEANS FOR DELAYING FOR A PREDETERMINED TIME PERIOD THE CARRY TRANSMISSION AFTER SUCH CARRY APPEARS IN THE RESPECTIVE ONE OF SAID FLIP-FLOP STAGES; CORRECTION MEANS ARRANGED BETWEEN A SELECTED FLIP-FLOP STAGE BEING ASSIGNED TO THE HIGHEST BINARY DIGIT POSITION AND SAID PLURALITY OF INPUT MEANS AND APPLYING, WHEN ACTUATED TO SELECTED ONES OF SAID INPUT MEANS ELECTRICAL CORRECTION IMPULSES REPRESENTING A FIRST PREDETERMINED BINARY CORRECTION NUMBER WHEN THE ALGEBRAIC SUM OF SAID ONE-DIGIT DECIMAL NUMBERS IS LESS THAN 10, AND A SECOND PREDETERMINED BINARY CORRECTION NUMBER WHEN THE ALGEBRAIC SUM OF SAID ONE-DIGIT DECIMAL NUMBERS IS AT LEAST 10 AFTER TWO BINARY NUMBERS HAVE BEEN INTRODUCED INTO SAID STORAGE MEANS BY APPLICATION OF SAID INPUT PULSES; AND ACTUATING MEANS FOR ACTUATING SAID CORRECTION MEANS AFTER TWO BINARY NUMBERS HAVE BEEN INTRODUCED INTO SAID STORAGE MEANS, SAID ACTUATING MEANS INCLUDING SWITCH MEANS FOR DISCONNECTING SAID CORRECTION MEANS FROM SAID SELECTED FLIP-FLOP WHEN SAID CORRECTION MEANS ARE ACTUATED.
