Abstract: ABSTRACT            In a multinozzle ink jet printing system, a closed loop servo system drives the drop generator so that the distance between the streams at which ink droplets are detached is maintained at an optimum range.  One or more sensors are positioned downstream from the multinozzle plate of the ink jet printing system.  The sensors sense the flight time of ink droplets and output signals which are developed into a variable voltage for controlling the crystal generator.

Abstract: SOLAR ENERGY APPARATUS                             ABSTRACT     The solar energy apparatus of the present invention collects, concentrates, and transmits solar radiation to a light converter, which converts solar radiation to another energy form.  The apparatus includes aspheric reflectors which are used in conjunction with azimuth and altitude tracking means, which controls the position of the aspheric reflectors so that each reflector focuses the solar radiation to a  proximate a fixed first position as the sun's position changes during the day.          Optical waveguides have their first ends located at the fixed first position.  The second ends of the optical waveguides terminate at a light converter.  Solar radiation received at the first ends of the optical waveguides is transmitted through the optical waveguides to the second ends, where it is converted to thermal energy by the light converter.

Abstract: ABSTRACT       The invention relates to an apparatus for treatment of particulate mixtures such as a mixture of solid particles, which is to be depleted in, enriched by or treated with a fluid, or wherein the mixture acts as a treatment medium for a fluid passing through same.  The apparatus is of the type operating with an advancing bed of the particulate material. It utilizes walls permeable by at least a portion of the fluid. The apparatus is of the type of tubular, rectangular or the like vessel having only stationary parts and subdivided by a selected combination of permeable and non-permeable walls into separate chambers into or from which the fluid can be delivered or removed.  The movement of the particulate mixture is effected solely by forcing same through a passage having preferably but not exclusively an annular chamber, by pumping, by gravity or by a combination of both. Additional throttling or valve means are employed to selectively control the advancement of the bed through the device.  The device is simple in structure and can be relatively easily adjusted for a great variety of different operations, from plain filtering to a complex washing or treatment of the particulate bed with different liquids in order to extract desired matter from the raw bed.

Title: Dye imbibition imaging material including cationic mordant layer and photosensitive polyesterionomer layer
Inventor: MCGUCKIN HUGH G
IPC: G03F3/10
Filed: 1981-11-09
Granted: 1984-04-03
Abstract: A positive, continuous tone, dye image is produced by means of a dye imbibition imaging element comprising (a) a support having thereon, (b) a cationic mordant layer for an anionic dye, and (c) a senitized photohardenable photopolymer layer consisting essentially of a photosensitive polyesterionomer. A process for forming a positive, continuous tone dye image in a dye imbibition imaging element, as described, comprises the steps of: (1) imagewise exposing the photopolymer layer of the element to activating radiation to imagewise harden the photopolymer layer; then (2) developing the photopolymer layer by means of water rinsing; and, then (3) imbibing an anionic dye into the mordant layer through the unexposed areas of the photopolymer layer. Alternatively, the process comprises immersing the imagewise-exposed element from step (1) into a bath comprising the anionic dye without the need for a water rinsing step. This alternative process enables the anionic dye to be Imbibed into the mordant layer through the unexposed areas of the photopolymer layer without the need for removing a portion of the unexposed areas of the photopolymer layer. The anionic dye is optionally transferable into another mordant layer.

Abstract: Abstract of the Disclosure:     In an encoder responsive to a video signal variable between high and low levels, a logic converter logically converts a succession of result signals, derived from the video signal by the use of a predetermined number of halftone threshold levels, into a sequence of converted signals having that run length of logic "0" or "1" level which is longer than that in the result signal succession.  The converter may comprise a combination of adders and memory elements to process the consecutive result signals.          The converted signal sequence is encoded by an encoding circuit into a data-compression digitized signal.  In a decoder for decoding the digitized signal into a reproduction of the result signal succession, a logic inverter comprises a combination of adders and memory elements, similar to that of the converter.  The inverter processes, into the reproduction, signals derived from data-expansion decoding of the digitized signal.  Preferably, a dither matrix is used to provide the threshold levels.
