Claim 1
Independent Claim
123 words
APPARATUS FOR PERFORMING ARITHMETIC OPERATIONS COMPRISING DELAY MEANS CONSISTING SOLELY OF A SINGLE CONTINUOUS DELAY LINE, SAID SINGALE DELAY LINE HAVING AN INPUT TERMINAL AND A PLURALITY OF OUTPUT TAPS EQUALLY SPACED ALONG ITS LENGTH, THE FIRST OUTPUT TAP BEING DIRECTLY COUPLED TO THE INPUT TERMINAL, A LIKE PLURALITY OF CONDITIONABLE GATES RESPECTIVELY COUPLED TO EACH OF SAID OUTPUT TAPS, MEANS FOR CONDITIONING A SELECTED ONE OF SAID GATES PROPORTIONATELY REPRESENTING THE FIRST DIGIT IN AN ARITHMETIC OPERATION, AND MEANS FOR APPLYING TO SAID INPUT TERMINAL A SIGNAL PREDELAYED IN PROPORTION TO SAID OUTPUT TAPS TO REPRESENT A SECOND DIGIT IN SAID ARITHMETIC OPERATION WHEREBY A PULSE EMANATES FROM SAID CONDITIONED GATE WITH A DELAY PROPORTIONAL TO THE OUTCOME OF THE ARITHMETIC OPERATION.
