Arrangement for producing electric signals controlling the typing of typewriter signs defined by coordinates

Claim 1

IN A WRITING MACHINE OPERATING IN ACCORDANCE WITH A TWO COODINATE SYSTEM, TO PRODUCE SYMBOLS FROM CHARACTERISTIC FORM COMBINATIONS, AND INCLUDING A SUITABLE KEYBOARD MEANS AND COORDINATE CONTROLLED MARKING HEAD THEREIN; THE COMBINATION OF A SIGNAL GENERATOR HAVING A PLURALITY OF SIGNAL OUTPUS ADAPTED TO CONTINUOUSLY EMIT A LIKE PLURALITY OF PRESELECTED OUTPUT WAVEFORMS AT SAID OUTPUTS AND A CLOCK WAVE OUTPUT, A GATING SIGNAL GENERATOR SYNCHRONIZED WITH SAID SIGNAL GENERATOR BY SAID CLOCK WAVE OUTPUT AND INCLUDING A SECOND PLURALITY OF SIGNAL OUTPUS, A PLURALITY OF GATE CIRCUITS HAVING INPUT, OUTPUT AND GATE TERMINALS CONNECTED BY THE SAID GATE TERMINALS WITH SELECTED ONES OF SAID SECOND PLURALITY OF SIGNAL OUTPUTS, SAID PLURALITY OF GATE CIRCUITS INCLUDING GATES REPRESENTATIVE OF EACH COORDINATE IN SAID TWO COORDINATE SYSTEM, COUPLING CIRCUIT MEANS FOR EACH OF THE SIGNAL OUTPUTS AND RESPECTIVE PRESELECTED OUTPUT WAVEFORMS OF SAID SIGNAL GENERATOR, SELECTIVE INTERCONNECTING MEANS OPERATED BY SAID KEYBOARD MEANS FOR SELECTIVELY INTERCONNECTING SAID COUPLING CIRCUIT MENS TO SAID INPUT TERMINALS OF SAID GATE CIRCUITS IN RESPONSE TO ACTUATION OF SAID KEYBOARD MEANS, AND FIRST AND SECOND COORDINATE OUTPUT AMPLIFIERS, RESPONSIVE TO THE RESPECTIVE COORDINATE OUTPUTS FROM SAID REPRESENTATIVE GATE CIRCUITS, CONNECTED BETWEEN SAID OUTPUT TERMINALS OF SAID GATE CIRCUITS AND SAID MARKING HEAD.
