摘要： An electrophotographic system employing double image transfer. A photoconductive member is charged and exposed to form a latent electrostatic image, which is then transferred to a drum with a durable dielectric coating. The latent electrostatic image is subsequently toned and transferred by pressure to a recording medium, with or without simultaneous pressure fixing.

摘要： Electrostatic transfer printing in which a latent electrostatic image is formed on a cylindrical dielectrical member by means of a remote glow discharge ion source. The image is then toned and pressure-transferred to a receptor, such as a sheet of paper, which is passed between the cylindrical dielectric member and a transfer roller. Scraper blades may be included to remove residual toner from the cylindrical dielectric member and the transfer roller. Means may also be included to erase any latent residual electrostatic image on the cylindrical dielectric member.

摘要： Generation of charged particles, e.g. ions, by extracting them from a high density source provided by an electrical gas breakdown in an electric field between two conducting electrodes separated by an insulator. When a high frequency electric field is applied, surprisingly high ion current densities can be obtained, providing numerous advantages over conventional ion forming techniques for use in electrostatic printing and office copying, as well as in electrostatic discharging, precipitation, separation, and coating.

摘要： Imaging systems and methods are described. In one aspect, an ink layer having an electrorheological fluid composition including a suspension of colorant particles dispersed in an electrically insulating carrier fluid is formed on a surface. A charge image is projected onto the ink layer to selectively form charge-stiffened regions adhering to the electrically insulating layer and representing respective regions of the projected charge image. Non-charge-stiffened ink layer components are physically separated from the charge-stiffened regions. Portions of the ink layer are electrostatically transferred to a receptor substrate.

摘要： A method that intermittently or continuously introduces a known mass of fine powder into an aerosolization chamber. The dry powder is aerosolized and, in one preferred method, the aerosol powder charged. Charged powder is then electrostatically deposited into or onto unit dose package substrates as these packages are sequentially moved through the deposition region. The packages are arranged in a continuous line either around the circumference of a circular package transport or in a continuous line on the surface of an endless belt. As each package traverses the precipitation region, a small amount of powder is deposited. The number of packages, the package velocity and the aerosol deposition rate are selected so that a large number of passes are required to fill each package to the required dose level. It is this continuous sampling, or time division sampling (TDS), that very uniformly divides the pre-determined quantity of powder uniformly among the many packages.

摘要： An ion generator for the formation of electrostatic images, including two electrodes at opposite faces of a solid dielectric member, using a threshold multiplexing principle for the drive circuit. The apparatus provides a drive signal to each electrode to generate ions in an air region adjacent one of the electrodes, which ions are extracted for electrostatic imaging. Two drive signals each consisting of a sinusoidal alternating potential, out of phase by 180.degree., intermittently induce the production and extraction of ions. Other time-varying potentials of like electrical characteristics may be used, providing a number of operating advantages. The ion generator produces ions only during print periods, and requires reduced power to achieve given ion outputs. The control electrode may be partially encapsulated to limit the discharge region. Drive circuitry such as low source impedance gated oscillators, or other low impedance drivers, reduce capacitive "cross-talk" in a multielectrode device.

摘要： A corona charging device including a dielectric-coated elongate conductor contacting or closely spaced from a grid electrode, mounted against an insulating support. A high voltage varying potential between the elongate conductor and grid electrode induces a glow discharge in the vicinity of the dielectric-coated electrode. The grid electrode may act as a ground plane to provide a corona discharge device with respect to a proximate member. Alternatively, the grid electrode may be maintained at a desired potential to provide a charging device with an automatically limited voltage.

摘要： A printing apparatus for generating visible bar code images in accordance with an electronic input command which comprises: a conducting mask containing a slot, a fine diameter ion emitting wire positioned on one side of the mask and adjacent to this slot and an electrically conductive support member. An insulating latent charge image receiving member is transported at a uniform velocity while spaced a short distance from the slotted mask and on the side of the mask opposite the side to which the ion emitting wire is adjacent. A potential is applied between the slotted mask and the conducting support member upon which the insulating member rests. Conventional means are provided for electrostatically toning the latent image formed on the insulating surface and additional means are provided for fixing the toned image. Transport means are provided to move the insulating member, at a uniform velocity, through the latent image forming, toning, and fixing stations. The height of the bar code images formed is determined by the length of the slot in the mask and the widths of the bars are defined by the duration of the high voltage pulses applied to the ion emitting wire.

摘要： A method and article providing different images from differing viewing angles. The image side of a lenticular sheet is printed with radiation curable inks and cured using a collimated radiation source located at a viewer position with respect to the lenticular surface. Uncured ink is removed from the printed surface, and the resulting clear region of the imaging surface may be processed further in a variety of ways. The clear region may be left unprinted, or printed with a second image different from the first, or a stereoscopic image that combines with its pre-printed mate to form a three dimensional image. The clear region also may be vacuum metallized or chemically plated to form a highly reflective surface.
