Abstract: A method of producing viewable images is disclosed in accordance with the teachings of the present invention wherein a character pattern comprised of modulated radiant energy is transmitted onto a surface of superconducting material disposed in an external magnetic field. The external magnetic field is less than a critical field value such that the transmitted modulated radiant energy is effective to maintain certain portions of the surface of superconducting material in their respective normal states in accordance with the character pattern when the ambient temperature is decreased below a critical temperature value, whereby magnetic flux penetrates said certain portions. Upon decreasing the ambient temperature, the superconductivity of said superconducting material is obtained and the penetrated magnetic flux is trapped in said certain portions to form a magnetostatic latent image of the transmitted character pattern. The magnetostatic latent image is then developed to form a viewable image of the character pattern. Alternatively, the superconducting material initially admits of its superconducting state and the transmitted modulated radiant energy is effective to quench the superconductivity of certain portions thereof whereby magnetic flux penetrates said certain portions. The penetrated magnetic flux is trapped in said certain portions upon the restoration of the superconductivity thereof.

Abstract: An exposure medium for producing a reflex exposure of an original image onto a photosensitive surface including a transparent conductive member adapted for positioning proximate to the original image to be reproduced. The exposure medium further includes an opaque conductive member spaced from the transparent conductive member and adapted for positioning proximate to the photosensitive surface. A luminescent member is positioned between the transparent conductive member and the opaque conductive member and is adapted when energized to illuminate the original image through the transparent conductive member. A plurality of light conductive members are disposed throughout the opaque conductive member and the luminescent member for conducting patterns of light reflected from the original image through the opaque conductive member and thus exposing the photosensitive surface according to the reflected light patterns. The light conductive members include light insulating means associated therewith and with the luminescent member for preventing the direct illumination of the luminescent member from reaching the photosensitive surface.

Abstract: Apparatus for effecting transfer of electroscopic toner particles from a surface carrying electrical charges in image configuration to a support medium. An electrically biased transfer roller having an outer peripheral surface of electrically isolated segments of a conductive resilient material is positioned adjacent the electrical charge carrying surface with the support medium passing therebetween. The electrically isolated conductive segments are selectively actuated in response to the length of the support medium to effect transfer of the electroscopic toner particles thereto to the exclusion of effecting transfer of the toner particles to the transfer roller surface.
