Semi-permanent memory

Claim 2

A SEMI-PERMANENT MEMORY APPARATUS COMPRISING A PULRALITY OF MAGNETIC TRANSFORMER ELEMENTS EACH COMPRISING A CORE OF MAGNETIC MATERIAL DEFINING A CLOSED FLUX PATH, EACH SAID CORE HAVING A SEPARABLE PORTION WHICH MAY BE REMOVED TO PERMIT BODILY INSETION OF A WINDING INTO FLUX COUPLING RELATION WITH SAID FLUX PATH, MEANS FOR INDIVIDUALLY EXCITING ANY SELECTED TRANSFORMED ELEMENT, AND A PLURALITY OF SENSE WINDINGS EACH COMPRISING A SERIES CONNECTION OF A PLURALITY OF OF PAIRS OF PARALLEL BRANCHES ARRANGED SO THAT THE WINDING MAY BE REMOVABLY ENGAGED WITH THE SEVERAL TRANSFORMER ELEMENTS IN SUCH A MANNER THAT ONE OF EACH PAIR OF PARALLEL BRANCHES IS IN FLUX COUPLING RELATION WITH ONE OF SAID CORES AND THE OTHER PARALLEL BRANCH IS NOT IN FLUX COUPLING RELATION WITH ANY CORE, SAID BRANCHES IN EACH OF SAID PAIRS OF PARALLEL BRANCHES BEING SELECTIVELY INTERRUPTIBLE TO RECORD AN INFORMATION PATTERN IN EACH SAID SENSE WINDING.

Claim 3

AN INFORMATION STORAGE APPARATUS COMPRISING A PLURALITY OF DRIVE LINES ADAPTED TO CARRY ELECTRIC CURRENT PULSES, A PLURALITY OF INDIVIDUAL INFORMATION STORAGE ELEMENTS ALONG EACH OF SAID DRIVE LINES, EACH OF SAID ELEMENTS BEING CONSTITUTED ASA A PAIR OF INTERRUPTIBLE CURRENT CARRYING ELEMENT LOOPS CONNECTED TO SAID DRIVE LINES IN SUCH A MANNER AS TO CAUSE A DRIVE LINE CURRENT PULSE TO FLOW THROUGH A FIRST OF SAID ELEMENT LOOPS WHEN A SECOND OF SAID ELEMENT LOOPS HAS BEEN INTERRUPTED AND TO CAUSE A DRIVE LINE CURRENT PULSE TO FLOW THROUGH SAID SECOND ELEMENT LOOP WHEN SAID FIRST ELEMENT LOOP HAS BEEN INTERRUPTED, EACH OF SAID PAIRS OF ELEMENT LOOPS INCLUDING A PORTION OF A CONDUCTIVE PATH COMMON TO BOTH OF SAID LOOPS THROUGH WHICH THE DRIVE LINE CURRENT FLOWS IN ONE DIRECTION WHEN SAID FIRST ELEMENT LOOP IS INTERRUPTED AND IN THE OPPOSITE DIRECTION WHEN SAID SECOND ELEMENT LOOP IS INTERRUPTED, AND SENSING MEANS IN ELECTROMAGNETICALLY-COUPLED RELATIONSHIP TO THE COMMON CONDUCTIVE PATH PORTION OF AT LEAST ONE PAIR OF ELEMENT LOOPS FOR IDENTIFYING THE DIRECTION IN WHICH A CURRENT PULSE FLOWS THERETHROUGH.

Claim 4

AN INFORMATION STORAGE APPARATUS COMPRISING A PLURALITY OF DRIVE LINES ADAPTED TO CARRY ELECTRIC CURRENT PULSES, A PLURALITY OF INDIVIDUAL INFORMATION STORAGE ELEMENTS ALONG EACH OF SAID DRIVE LINES, EACH OF SAID ELEMENTS BEING CONSTITUTED ASA A PAIR OF INTERRUPTIBLE CURRENT CARRYING ELEMENT LOOPS CONNECTED TO SAID DRIVE LINES IN SUCH A MANNER AS TO CAUSE A DRIVE LINE CURRENT PULSE TO FLOW THROUGH A FIRST OF SAID ELEMENT LOOPS WHEN A SECOND OF SAID ELEMENT LOOPS HAS BEEN INTERRUPTED AND TO CAUSE A DRIVE LINE CURRENT PULSE TO FLOW THROUGH SAID SECOND ELEMENT LOOP WHEN SAID FIRST ELEMENT LOOP HAS BEEN INTERRUPTED, EACH OF SAID PAIRS OF ELEMENT LOOPS INCLUDING A PORTION OF A CONDUCTIVE PATH COMMON TO BOTH OF SAID LOOPS THROUGH WHICH THE DRIVE LINE CURRENT FLOWS IN ONE DIRECTION WHEN SAID FIRST ELEMENT LOOP IS INTERRUPTED AND IN THE OPPOSITE DIRECTION WHEN SAID SECOND ELEMENT LOOP IS INTERRUPTED, AND SENSING MEANS IN ELECTROMAGNETICALLY-COUPLED RELATIONSHIP TO THE COMMON CONDUCTIVE PATH PORTION OF AT LEAST ONE PAIR OF ELEMENT LOOPS FOR IDENTIFYING THE DIRECTION IN WHICH A CURRENT PULSE FLOWS THERETHROUGH.
