Arithmetic element for digital computers

Claim 1

AN ARITHMETIC UNIT COMPRISING: A MATRIX COMPOSED OF MAGNETIC CORES HAVING A RECTANGULAR HYSTERESIS LOOP ARRANGED IN A PREDETERMINED NUMBER OF ROWS AND COLUMNS, A BUFFER STORAGE COMPRISING A PLURALITY OF STORAGE ELEMENTS AT LEAST EQUAL IN NUMBER TO THE NUMBER OF COLUMNS IN THE MATRIX, EACH STORAGE ELEMENT HAVING AT LEAST ONE INPUT TERMINAL WHICH IS COUPLED TO A FIRST PLURALITY OF CORES IN A PREDETERMINED MANNER BY MEANS OF A WIRE CONNECTED TO SAID INPUT TERMINAL AND THREADING SAID FIRST PLURALITY OF CORES IN SERIES, EACH STORAGE ELEMENT ALSO COMPRISING AN OUTPUT TERMINAL COUPLED TO A SECOND PLURALITY OF CORES IN A PREDETEMRINED MANNER BY MEANS OF A WIRE CONNECTED TO SAID OUTPUT TERMINAL AND THREADING SAID SECOND PLURALITY OF CORES IN SERIES, FIRST CURRENT SOURCES COUPLED TO SELECTED MATRIX ROWS, MEANS FOR SELECTIVELY ACTUATING SAID FIRST CURRENT SOURCES TO TRANSFER INFORMATION FROM THESE ROWS SELECTIVELY TO THE ASSOCIATED STORAGE ELEMENTS, THE CURRENT GENERATED BY EACH OF SAID FIRST SOURCES HAVING AN AMPLITUDE SUFFICIENT TO CHANGE-OVER AN ASSOCIATED CORE FROM ONE REMANENT CONDITION TO ANOTHER, SECOND CURRENT GENERATED BY EACH SECSELECTED MATRIX ROWS, THE CURRENT GENERATED BY EACH SECOND SOURCE AND EACH STORAGE ELEMENT HAVING ONE-HALF THE AMPLITUDE SUFFICIENT TO CHANGE-OVER AN ASSOCIATED CORE FROM ONE REMANENT CONDITION TO ANOTHER, MEANS FOR SELECTIVELY ACTUATING SAID SECOND CURRENT SOURCES AND SIMULTANEOUSLY ACTUATING SAID STORAGE ELEMENTS, THEREBY TRANSFERRING BY COINCIDENCE THE INFORMATION STORED BY SAID STORAGE ELEMENTS IN SELECTED CORES, THE WIRES COUPLING SAID CURRENT SOURCES AND STORAGE ELEMENTS TO ASSOCIATED CORES BEING WOUND ON SAID CORES IN A DIRECTION AND WITH A NUMBER OF TURNS SUCH THAT THE SUM OF TWO NUMBERS INITIALLY STORED IN THE MATRIX IS SUBSEQUENTLY STORED IN THE MATRIX.
