Abstract: An electrostatic recording device in which an area on a record carrier is charged electrically. Electrodes are arranged on both sides of the carrier. The print electrodes arranged in groups on one side thereof serve to form the desirable charge image. The counter electrodes on the other side, serve to select the desirable print electrode group. The counter electrodes being arranged in spaced opposing relationship with portions of two groups of print electrodes. The print electrodes are arranged in even and odd groupings, with each alternating group set being electrically connected.

Abstract: A voltage switching device operable by an electric power source comprises a gas discharge panel that includes opposing first and second electrodes and gas discharge cells therebetween. Resistors are connected between the power source and the respective first electrodes and switching means are connected between the power source and the second electrodes. In consideration of the power source terminal voltage and of the firing voltage of the gas discharge cells, the resistance values of the resistors are determined so as to prevent the gas discharge from spreading over the entire area of each gas discharge cell.

Abstract: An electrostatic image of graphical information is formed on a surface, for example that of an endless tape, a drum or suitable paper, and then magnetic toner particles are applied to the surface and adhere thereto in correspondence with the electrostatic image. Portions of the same surface, in the case of the tape, or of another surface, when the drum or paper are employed, are magnetized, as determined by the location of the toner prticles, to form a magnetic image corresponding to the electrostatic image. Then the toner medium are transferred by friction to a copy mdium such as ordinary paper, while the magnetic image is retained or stored on the surface. Toner particles then again can be applied to the magnetic image for production of additional copies. In other embodiments, magnetic material located on a surface in correspondence with graphical information, such as a hard copy comprising magnetic toner particles fixed to a paper substrate, is utilized in magnetizing a surface such as that of a drum or an endless tape, to form a magnetic image of the graphical information. The magnetic image can have toner particles applied thereto for photocopying by transfer to a copy medium such as paper, or it can be scanned to generate a sequential electrical signal indicative of the graphical information which signal is compatible with computer forms of storage and processing.

Abstract: A system for electrostatic printing including a corona source and electrode for coulombs/m.sup.a substantially uniform stream of ions in the direction of a print receiving medium and a multilayer apertured modulator interposed in the ion stream for modulating the cross-sectional flow density of ions in the stream in accordance with a pattern to be reproduced. A cloud of substantially uncharged liquid aerosol ink particles is introduced adjacent the print receiving medium whereby the modulated ion stream selectively impinges upon and charges particles in the cloud which are thereby accelerated and deposited on the print receiving medium in accordance with the pattern to be reproduced. The average surface charge density on liquid aerosol particles in the cloud is no greater than about 1 .times. 10.sup.-.sup.6 coulombs/m.sup.2, and preferably no greater than about 5 .times. 10.sup.-.sup.7 coulombs 2. The liquid aerosol droplets are in the range of from about 0.10 micron to 50.0 microns in diameter, the range of 1.0-10.0 microns diameter being preferred.

Abstract: 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.

Abstract: The blades of a rotary blasting machine are removably mounted on a rotor bracket in a spaced relationship with the bracket outwardly from a point of contact at the inner extremity of the blade-bracket junction. Preferably, the space diverges outwardly, and an inner portion of the blade hooks over the bracket to resist centrifugal force acting on the blade, and also seal the junction against ingress of abrasive particles.
