    摘要： A MAGNETIC MEMORY FOR STORING NUMBERS OR INFORMATION, WHICH MAY BE IN CODED FORM. THE MEMORY IS IN THE FORM OF JUXTAPOSED MAGNETIC TRACKS ON A MAGNETIC DRUM, PREFERABLY HAVING A SMALL DIAMETER AND ADAPTED TO COOPERATE WITH AT LEAST ONE MAGNETIC HEAD IN ORDER TO RECORD SAID NUMBERS OR INFORMATION IN SAID MEMORY, AND A PULSUCONTROLLED STEP-BY-STEP MOTOR FOR DRIVING SAID DRUM WHICH TURNS THROUGH A PREDETERMINED ANGLE IN RESPONSE TO EACH PULSE. THE DEVICE MAY COMPRISE MEANS FOR DERIVING FROM SAID MEMORY SIGNALS WHICH WILL CAUSE THE TRANSMISSION OF A TELEPHONE NUMBER OVER A TELEPHONE LINE.
