Binary-to-decimal decoding matrix using static switches

Claim 1

A MAGNETIC MATRIX DECODER FOR CONNECTING AN INPUT TERMINAL SELECTIVELY TO ONE OF TEN OUTPUT TERMINALS TO PROVIDE AN OUTPUT CHEMICAL SYSTEM NUMERICAL INDICATION OF A MULTIPLE BIT BINARY INPUT, SAID MATRIX COMPRISING, IN COMBINATION, A PLURALITY OF MAGNETIC SWITCHING ELEMENTS ARRANGED ELECTRICALLY AT SELECTED INTERSECTIONS OF COLUMNS AND ROWS, WITH THE COLUMNS CORRESPONDING TO RESPECTIVE BINARY INPUTS BITS AND THE ROWS CORRESPONDING TO RESPECTIVE NUMERICAL DIGITS IN THE DECIMAL SYSTEM; EACH ELEMENT COMPRISING A PAIR OF ANNULAR CORES OF MAGNETIC MATERIAL ARRANGED IN SUBSTANTIALLY COPLANAR JUXTAPOSED RELATION; A LOAD WINDING ON EACH CORE, THE LOAD WINDINGS ON THE CORES OF EACH PAIR HAVING THE SAME NUMBER TURNS AND BEING CONNECTED IN SERIES OPPOSITE; A SOURCE OF A.C. POTENTIAL; A MATRIX INPUT TERMINAL CONNECTION TO ONE TERMINAL OF SAID SOURCE; A PLURALITY OF MATRIX OUTPUT TERMINALS EACH CORRESPONDING TO A RECEPTIVE ONE OF SAID ROWS; A PLURALITY OF DIGIT INDICATORS EACH CONNECTED BETWEEN A RESPECTIVE OUTPUT TERMINAL AND THE OTHER TERMINAL OF SAID SOURCE, EACH DIGIT INDICATOR CORRESPONDING TO A RESPECTIVE BINARY CODE INPUT; SAID LOAD WINDINGS BEING CONNECTED IN CASCADE BETWEEN SAID INPUT TERMINAL AND SAID OUTPUT TERMINALS; THE NUMBER AND COLUMN POSITION OF THE SAID ELEMENTS CONNECTED TO A RESPECTIVE OUTPUT TERMINAL CORRESPONDING TO THE BINARY CODE REPRESENTATION OF THE DIGIT OF THE ASSOCIATED INDI-
