Abstract: This invention provides an ink mist type high speed printer in which an aperture board is provided between a first electrode and a second electrode across which a high voltage is applied. The aperture board is adapted to selectively control passage of ions generated from the second electrode, and a stream of ink mist is passed between said aperture board and first electrode so that the ions which have passed said aperture board will electrically charge the ink mist particles selectively to let the electrically charged ink mist particles deposit on a recording paper placed between the ink mist and first electrode to thereby print the desired dot matrix characters. This invention also features provision of electrostatic shields placed between said first electrode and ink mist stream and at places outside of the desired printing space to guard the aperture board against deposition of ink mist particles.

Abstract: An electrophotographic print marking apparatus for printing markings on rolled steel plates while the steel plates are being fed in a heated condition. A part of an image transfer belt which is brought to a transfer section where the powder image carried by the belt is transferred to the steel plate is made movable up and down by means of a pair of lower rollers. The rollers are moved up and down to bring the part of the belt in the transfer section close the steel plates when the powder image is transferred to the steel plates and to separate the belt far apart from the steel plates when the powder image is not transferred. A tension roller is provided to absorb the change in tension of the transfer belt accompanying the up and down movement of the lower rollers.

Abstract: A method and apparatus for developing an electrographic-latent image on a pre-treated paper medium, by utilizing multiple rollers partially dipped in a liquid carrier.A pre-treated paper medium comprised of a conductively treated paper base supporting a plastic dielectric coating on each of its sides, is positioned between electrode assemblies comprised of matrices of a plurality of styli which receive variable information in the form of electronic signals from a data processor, or other equipment and by selectively changing the plurality of styli generating a latent electrographic image of alphanumeric characters or other variable printing by electrostatic discharge on the paper which is retained by the coating.The latent image is developed, i.e., made visible, by subjecting the paper medium to charged toning particles suspended in a liquid toning carrier. Multiple rollers, one each at predetermined locations, are partially submerged in a liquid toning carrier and pick up sufficient toning so as to form a meniscus between the upper portions of each roller and the paper medium. The image is then fixed i.e., made permanent by vaporizing the liquid carrier with heat.

Abstract: A method and apparatus for transfer printing a toner image from an image forming surface to the surface of a recording sheet by means of a transfer printing member electrically charged to have the same polarity as the electrostatic latent image on the image forming surface. The recording sheet is initially engaged with the image forming surface before engaging the transfer printing member, and then is fed to the transfer printing station while pressed against the image forming surface with a low pressure by the transfer printing member to effect a toner image transfer printing. The recording sheet is subsequently separated from the image forming surface while being electrostatically supported by the transfer printing member.

Abstract: Butadiene copolymers having controlled electrical life and controlled resistivity are described. A method is disclosed for enhancing the electrical life of butadiene copolymers having solubilized conductivity control agents incorporated therein by varying specified quantities of terminally unsaturated hydrocarbon nitriles in copolymers of the butadiene and the specified nitriles by using mixtures of such copolymers having conductivity control agents therein. The method and polymers are useful for enhancing the electrical life and polymer stability in xerographic devices where control of conductivity and/or relaxation behavior is important, e.g., in bias transfer rolls.
