Abstract: 893,842. Charging with static electricity. BURROUGHS CORPORATION. Jan. 29, 1959 [Feb. 12, 1958], No. 3250/59. Class 35. [Also in Groups XVI and XX] An electrographic recording process comprises forming electrostatic images on selected portions of a record having a dielectric layer 30 of high resistivity secured upon a backing layer of substantially lower resistivity, thereafter establishing an electrically-conductive circuit externally between the two layers and through a development medium, so a visual image is produced at the selected portions of the record. Latent character images are formed by a series of spots in the exposed surface 31 of the record 10, by seven electrodes 18 pulsed by devices 24-28, as it passes over a back electrode 14. After the character images have been established as charged areas on the dielectric layer 30, the record enters an inking station 40 comprising a housing 42 filled with a powdered conducting ink 44 which is of sufficient depth to surround the record. Vibrators 46, baffles 48 and a vacuum cleaner 50 remove ink from the uncharged areas and the ink on the charged areas is fixed at a heating station 60 and by calendering rollers 64. The record 10 has a resistivity of not less than 10<SP>13</SP> ohm centimetres and comprises a thin dielectric layer 30 of approximately 0.0005 inch thick polyethylene to which has been added 15% titanium dioxide as a pigment. The backing layer has a resistivity of not more than 10<SP>9</SP> ohm centimetres of approximately 0.003 inch thick dry unbleached Scandinavian pulp with or without alum or sizing, plus a certain amount of carbon black.
