Abstract: An electrophoretic imaging process wherein a suspension of particles in a carrier liquid are placed between a photoconductive electrode and a second electrode. With an electrical field applied between the photoconductive electrode and the second electrode the photoconductor is exposed to imagewise radiation which causes particles on the surface of the photoconductive electrode to be driven away in image configuration by charge exchange with the photoconductive electrode. The migrating particles form a negative image on the second electrode leaving a positive image behind on the photoconductive electrode.

Abstract: A transport arrangement for an elongated relatively thin web or continuous sheet of material comprises a means for transporting the material in contact with an electrically conductive body formed of an electrically conductive mat and a plurality of electrically conductive contact members extending from the mat and which are secured to the mat and are in electrical contact with the mat. The web or sheet is engaged by the conductive body at distal segments of the contact members thereby supporting and spacing the material from the mat while the material is transported. The conductive body is positioned on a transport for movement therewith and imparts motion to the web or sheet. Alternatively, the conductive body is maintained stationary and the material is drawn across the body. Through this arrangement the web or sheet is spaced from the surfaces of the transport and other support surfaces thereby advantageously resisting the adhesion of a charged web or sheet to the surface of the transport surface. Additionally, the contact between the contact members and transported material provides countercharge with relatively firm, well defined local contact thereby avoiding sparking and attendant degradation of the sheet.

Abstract: A contact reflex manifold imaging process is provided wherein a manifold set comprising an electrically photosensitive imaging layer in a screen pattern releasably resides on a transparent donor sheet and is in contact with a transparent receiver sheet. A master to be copied is placed in contact with one side of the manifold set and is exposed to electromagnetic radiation to which the imaging layer is sensitive by passing the electromagnetic radiation through the manifold set while the imaging layer is subjected to an electric field. Upon separation of the manifold set while under a field and after the exposure, a positive image is observed on one of the donor and receiver sheets and a negative image is observed on the other sheet.

Abstract: Apparatus in which graphic information is simultaneously displayed and reproduced. Images of material on microfilm are projected toward a photoreceptor consisting of an electrostatically charged photoconductive element, to form an electrostatic latent image which is later developed. The optical path from the original material to the photoreceptor is intercepted by an image-splitting dichroic reflector or interference filter, which reflects a spectral portion of the image to a viewing screen. After passing through the reflector the unreflected spectral portion impinges on the charged photoreceptor to form the latent image. The reflector or filter is chosen so that the wavelength range of the light passing through it corresponds to the range of maximum sensitivity of the photoreceptor. To scan the image a shield having a slit moves laterally across the photoreceptor; adjacent to the slit and immediately preceding it is a charging unit to charge the photoreceptor before exposure.
