Output circuit for magnetic core memory in a high speed printer

Claim 1

A MEMORY SYSTEM COMPRISING A GROUP OF ARRAYS OF MAGNETIC CORES, A SERIES OF FIRST SELECTION LINES ALONG WHIH SAID CORES OF SAID GROUP OF ARRAYS ARE ARRANGED AND WITH WHICH SAID CORES OF SAID GROUP OF ARRAYS COMMUNICATE MAGNETICALLY, A SERIES OF SECOND SELECTION LINES ALONG WHICH SAID CORES OF SAID GROUP OF ARRAYS ARE ARRANGED AND WITH WHICH SAID CORES OF SAID GROUP OF ARRAYS COMMUNICATE MAGNETICALLY, SAID FIRST SELECTION LINES AND SAID SECOND SELECTION LINES BEING DISCRETE ELECRICALLY AND BEING CROSSED GEOMETRICALLY, EACH OF SAID CORES BEING CAPABLE OF ASSUMING EITHER OF TWO ALTERNATE STABLE MAGNETIC STATES, EACH OF SAID CORES BEING POSITIONED AT AN INTERSECTION OF ONE OF SAID FIRST SELECTION LINES AND ONE OF SAID SECOND SELECTION LINES, A GROUP OF INHIBIT LINES, ONE EACH OF SAID INHIBIT LINES BEING MAGNETIALLY ASSOCIATED WITH ONE EACH OF SAID ARRAYS OF CORES, A GROUP OF SENSE LINES, ONE EACH OF SAID SENSE LINES BEING MAGNETICALLY ASSOCIATED WITH ONE EACH OF SAID ARRAYS OF CORES, MEANS FOR SEQUENTIALLY DRIVING SAID FIRST SELECTION LINES, SAID SECOND SELECTION LINES AND SAID INBIBIT LINES IN ORDER TO LOAD SAID CORES OF SAID GROUP, MEANS FOR PRODUCING A SUCCESSION OF GROUP OF FIRST SIGNALS, MEANS FOR SEQUENTIALLY DRIVING SAID FIRST SELECTION LINES, AND SAID SECOND SELECTION LINES IN ORDER TO UNLOAD SAID CORES OF SAID GROUP WITH SAID SUCCESSION OF GROUPS OF FIRST SIGNALS ON SAID SENSE LINE THROUGHOUT A FIRST PREDETERMINED CYCLE, AN OUTPUT UNIT INCLUDING ELEMENTS REPRESENTING CHARACTERS, MEANS FOR OPERATING SAID ELEMENTS OF SAID OUTPUT UNIT CORRESPONDING TO SAID FIRST SIGNALS OF SAID SEQUENCE, SAID LAST MENTIONED MEANS OPERATING THROUGHOUT A SECOND PREDETERMINED CYCLE HAVING DIFFERENT PARTS, DIFFERENT ONES OF SAID CHARACTERS BEING PRESENTED BY SAID ELEMENTS DURING DIFFERENT PARTS OF SAID SECOND PREDETERMINED CYCLE, SAID FIRST PREDETERMINED CYCLE FALLING WITHIN EACH OF SAID DIFFERENT PARTS OF SAID SECOND PREDETERMINED CYCLE, MEANS SYNCHRONIZED WITH SAID OUTPUT UNIT FOR PRODUCING A SUCCESSION OF GROUPS OF SECOND SIGNALS, COMPARATOR MEANS FOR ACTUATING SAID OUTPUT UNIT IN THE EVENT THAT ONE OF SAID FIRST SIGNALS CORRESPONDS TO ONE OF SAID SECOND SIGNALS, SAID OUTPUT UNIT BEING A PRINTING MEANS INCLUDING A ROTATABLE DRUM PRESENTING LIKE CHARACTERS IN ROWS AND UNLIKE CHARACTERS IN COLUMNS, AND A REGENERATIVE BUFFER MEMORY INTERPOSED BETWEEN SAID COMPARATOR MEANS AND SAID GROUP OF SENSED LINES, SAID BUFFER MEMORY BEING CAPABLE OF PRODUCING A TEMPORARY RECORD CORRESPONDING TO SAID GROUP OF FIRST SIGNALS AND TRANSMITTING A GROUP OF SIGNALS TO SAID COMPARATOR MEANS AND THROUGH SAID INHIBIT LINES AT THE SAME TIME.
