    摘要： Information on a patient chart is imaged onto a first portion of a dielectric receptor sheet simultaneously with, prior to or subsequent to exposure of a second portion of the receptor sheet to object-modulated X-rays in an ionography imaging chamber. The sheet has an outer layer consisting of polyvinyl chloride or polyethylene terephthalate and is brought into intimate contact with a chart at a station where the chart and the overlapping first portion of the sheet are exposed to electromagnetic radiation issuing from an electronic flash unit. This results in the formation of a latent image of the information on the first sheet portion, and such image is thereupon converted into a visible image, either on the receptor sheet or on a separate sheet, in accordance with a xerographic developing technique by resorting to toner particles. The sheet can be reused by neutralizing its charge, e.g., by heating its layer to a temperature approximately 10.degree. C. above the freezing point of the material of the layer, by moving the sheet relative to an AC corona discharge device (or vice versa), or by washing the layer with alcohol.

    摘要： There is disclosed a process of the manufacture of reprographic sheets for use in electrostatography and papers produced thereby. In this method a coating composition is applied to a substrate, generally paper, out of a solution of a mixture of mutually miscible organic liquids, one being a solvent for the polymer and the other a non-solvent for the polymer and removing the organic liquids with most of the solvent being removed before a significant amount of non-solvent is removed.
