Apparatus and method for duplicating messages which are electrostatically charged, developed and fixed on a master dielectric medium onto copy media capable of retainingelectrostatic charges

Claim 1

A METHOD OF REPRODUCING A PATTERN OF CONDUCTIVE INK DISPOSED AND FIXED ON A CHARGED PATTERN OF A DIELECTRIC LAYER OF A FIRST RECORDING MEDIUM WHEREIN THE MEDIUM COMPRISES A RELATIVELY CONDUCTIVE LAYER AND SAID DIELECTRIC LAYER, SAID METHOD COMPRISING REMOVABLY POSITIONING SAID MEDIUM WITH ITS CONDUCTIVE LAYER DISPOSED IN FACING RELATIONSHIP TO A FIRST CONDUCTIVE MEMBER, REMOVABLY POSITIONING A SECOND RECEIVING RECORDING MEDIUM WHICH IS CAPABLE OF RETAINING ELECTROSTATIC CHARGES CLOSELY ADJACENT TO AND HAVING A FIRST SURFACE FACING THE INKED AND FIXED PATTERN SURFACE OF SAID FIRST MEDIUM, SUPPORTING SAID SECOND MEDIUM ON TIS MEDIUM SURFACE OPPOSITE SAID FIRST SURFACE CONTIGUOUS TO A SECOND CONDUCTIVE ANVIL MEMBER, BIASING SAID FIRST CONDUCTIVE MEMBER WITH RESPECT TO SAID SECOND CONDUCTIVE MEMBER SUCH THAT THE DIFFERENCE IN POTENTIAL BETWEEN SAID FIRST AND SECOND MEMBERS IS SUFFICIENT TO CAUSE IONIC DISCHARGE FROM SAID FIXED CONDUCTIVE INK OF SAID FIRST RECORDING MEDIUM TO SAID SECOND RECORDING MEDIUM; SAID FIRST MEDIUM CONDUCTIVE PATTERN DISHCARGING A MIRROR IMAGE OF ITSELF UPON SAID RECEIVING RECORDING MEDIUM THROUGH THE FILED CAUSED BY THE VOLTAGE BETWEEN THE FIRST CONDUCTIVE MEMBER WHICH IS CONTIGUOUS TO SAID FIRST TAPE CONDUCTIVE LAYER AND THE REMOVED VOLTAGE OF SAID SECOND CONDUCTIVE MEMBER, REMOVING SAID SECOND MEDIUM AWAY FROM SAID ANVIL MEMBER, INKING SAID SECOND MEDIUM TO FORM A VISIBLE INKED COPY, FIXING THE INK ON SAID INKED COPY AND REMOVING SAID FIRST MEDIUM AWAY FROM SAID FIRST CONDUCTIVE MEMBER.
