Read-out and transmission of electrostatic information presentations

Claim 1

A SYSTEM FOR TRANSMITTING INFORMATION REPRESENTED IN THE FORM OF AN ELECTROSTATIC PATTERN UPON A DIELECTRIC SURFACE FROM A FIRST STATION TO A SECOND STATION, COMPRISING: (I) A READ-OUT APPARATUS AT SAID FIRST STATION, AND A READIN APPARATUS AT SAID SECOND STATION, SAID READ-OUT APPARATUS COMPRISING: (A) A CATHODE RAY TUBE HAVING A PLURALITY OF ELECTRICALLY CONDUCTIVE PIN PASSING THROUGH THE TARGET WALL, (B) MEANS TO ADVANCE THE ELECTROSTATIC CHARGE PATTERN PAST AND CLOSELY ADJACENT THE ENDS OF SAID PINS LYING OUTSIDE THE CATHODE RAY TUBE, (C) MEANS TO SCAN THE CATHODE RAY BEAM ACROSS THE ENDS OF SAID PINS LYING INSIDE THE CATHODE RAY TUBE, (D) MEANS TO DEVELOP AN ELECTRICAL OUTPUT SIGNAL IN SYNCHRONISM WITH THE SCANNING OF THE PINS BY THE CATHODE RAY BEAM AND HAVING AN INSTANTANEOUS MAGNITUDE PROPORTIONAL TO THE POTENTIAL DIFFERENCE BETWEEN THE PIN BEING SCANNED AND THAT PORTION OF THE ELECTROSTATIC PATTERN OPPOSITE SAID PIN DEPENDING ON THE MAGNITUDE OF THE PORTION OF THE ELECTROSTATIC CHARGE PATTERN OPPOSITE THE PIN BEING SCANNED, (II) SAID READ-IN APPARATUS COMPRISING: (A) MEANS FOR RECEIVING SAID OUTPUT SIGNAL, (B) A CATHODE RAY TUBE HAVING A PLURALITY OF ELECTRICALLY CONDUCTIVE PINS PASSING THROUGH THE TARGET WALL, (C) MEANS TO ADVANCE A CHARGE RECEPTIVE DIELECTRIC MATERIAL PAST AND CLOSELY ADJACENT THE ENDS OF SAID PINS LYING OUTSIDE THE CATHODE RAY TUBE, (D) MEANS TO SCAN THE CATHODE RAY BEAM ACROSS THE ENDS OF SAID PINS LYING INSIDE THE CATHODE RAY TUBE IN SYNCHRONISM WITH THE SCANNING BEAM IN SAID READ-OUT APPARATUS, AND (E) MEANS TO INTENSITY MODULATE THE CATHODE RAY BEAM IN ACCORDANCE WITH SAID RECEIVED OUTPUT SIGNAL THEREBY FORMING ON SAID DIELECTRIC MEDIUM AN ELECTROSTATIC CHARGE PATTERN CORRESPONDING TO SAID ORIGINAL ELECTROSTATIC CHARGE PATTERN.

Claim 2

A SYSTEM FOR TRANSMITTING INFORMATION REPRESENTED IN THE FORM OF AN ELECTROSTATIC PATTERN UPON A DIELECTRIC SURFACE FROM A FIRST STATION TO A SECOND STATION, COMPRISING: (I) A READ-OUT APPARATUS AT SAID FIRST STATION, AND A READIN APPARATUS AT SAID SECOND STATION, SAID READ-OUT APPARATUS COMPRISING: (A) A CATHODE RAY TUBE HAVING A PLURALITY OF ELECTRICALLY CONDUCTIVE PIN PASSING THROUGH THE TARGET WALL, (B) MEANS TO ADVANCE THE ELECTROSTATIC CHARGE PATTERN PAST AND CLOSELY ADJACENT THE ENDS OF SAID PINS LYING OUTSIDE THE CATHODE RAY TUBE, (C) MEANS TO SCAN THE CATHODE RAY BEAM ACROSS THE ENDS OF SAID PINS LYING INSIDE THE CATHODE RAY TUBE, (D) MEANS TO DEVELOP AN ELECTRICAL OUTPUT SIGNAL IN SYNCHRONISM WITH THE SCANNING OF THE PINS BY THE CATHODE RAY BEAM AND HAVING AN INSTANTANEOUS MAGNITUDE PROPORTIONAL TO THE POTENTIAL DIFFERENCE BETWEEN THE PIN BEING SCANNED AND THAT PORTION OF THE ELECTROSTATIC PATTERN OPPOSITE SAID PIN DEPENDING ON THE MAGNITUDE OF THE PORTION OF THE ELECTROSTATIC CHARGE PATTERN OPPOSITE THE PIN BEING SCANNED, (II) SAID READ-IN APPARATUS COMPRISING: (A) MEANS FOR RECEIVING SAID OUTPUT SIGNAL, (B) A CATHODE RAY TUBE HAVING A PLURALITY OF ELECTRICALLY CONDUCTIVE PINS PASSING THROUGH THE TARGET WALL, (C) MEANS TO ADVANCE A CHARGE RECEPTIVE DIELECTRIC MATERIAL PAST AND CLOSELY ADJACENT THE ENDS OF SAID PINS LYING OUTSIDE THE CATHODE RAY TUBE, (D) MEANS TO SCAN THE CATHODE RAY BEAM ACROSS THE ENDS OF SAID PINS LYING INSIDE THE CATHODE RAY TUBE IN SYNCHRONISM WITH THE SCANNING BEAM IN SAID READ-OUT APPARATUS, AND (E) MEANS TO INTENSITY MODULATE THE CATHODE RAY BEAM IN ACCORDANCE WITH SAID RECEIVED OUTPUT SIGNAL THEREBY FORMING ON SAID DIELECTRIC MEDIUM AN ELECTROSTATIC CHARGE PATTERN CORRESPONDING TO SAID ORIGINAL ELECTROSTATIC CHARGE PATTERN.
