Abstract: ABSTRACT OF THE DISCLOSURE:    This invention relates to a process for cooling hot granular solids.  According to this process, granular solids at temperatures of about 400 to 1300°C are maintained in a cooling zone in an agitated or trickling state and air is caused to rise through the cooling zone in direct contact with the solids.  At least part of the contact heat of the solids is dissipated and recovered in view of being utilized.          The solids to be cooled may be obtained by dry distillation of oil sand, oil shale, oil chalk, diatomaceous earth or native asphalt.  solids which contain 1 to 15% by weight carbon may be burnt at least in part in a combustion chamber supplied with combustion air and may then be fed at tempera-tures of about 600 to 1300°C to the cooling zone.  This process is particularly interesting.

Abstract: Abstract of the Disclosure An internal combustion engine (10) has an intake manifold (12) including runners (14) connected to the engine at the intake ports (16) thereof for delivering a combustible mixture to the cylinders (20) of the engine.  Flow modification members (22) are positioned in the paths of flow to the cylinders (20) and these members are located upstream but in close proximity to the engine intake ports (16).  Each flow modification member (22) comprises generally planar faced flow restricting structure (24) arranged effectively to reduce the cross-sectional area of the flow path so that the cross-sectional area at the point in the flow path of most reduced area divided by the displacement of one of the cylinders is 0.03 square inches per cubic inch or less to thereby disrupt the flow of the combustible mixture and increase its velocity just prior to delivery to the intake ports of the engine.  Such flow modification provides efficient and more complete combustion of the mixture which results in economy gains up to 20%. Exhaust gas from the engine may be recirculated into the manifold for combining with the air/fuel mixture delivered to the cylinders of the engine to offset the emission of oxides of nitrogen which might otherwise occur.

Abstract: Abstract of Disclosure Apparatus for producing microform records from computer stored data or other electrical data signal sources forms on the screen of a cathode ray tube at rapidly occuring intervals suc-cessive hard copy-appearing images of such data which is reduced in size by a bundle of tapered fiber optic filaments with a wide light receiving end encompassing the screen of the cathode ray tube and a narrow light projecting end encompassing an area of the frame of a microfiche card.  The succesively produced images at the narrow end of the fiber optic filament bundle are applied to succesive frames of a heat developable masking film strip requiring more time to develop than the imaging intervals and moved in step-by-step fashion past the narrow end of the film optic bundle, a heating bar and an image transfer station where a flash of light is passed through the masking film strip to transfer a negative image thereon to a frame of an archival add-on microfich card-forming film.  The transfer of a cathode ray tube image to the masking film, the application of a heating bar to a previously imaged frame of the masking strip and the transfer of a previously imaged portion of the masking film may take place simultaneously-The heating bar has a length several frame lengths long so that a frame of the masking film is completely developed over several imaging intervals.

Abstract: Docket H4068         MODULAR AMPLIFIER WITH DISCRETE POWER  FRA: lhw                     REDUCTION SWITCHING     ABSTRACT OF THE INVENTION                     A modular amplifier comprising a plurality of modules receives a signal to be amplified and provides an amplified signal through power divider and power combiner circuits which are mirror images of each other. In particular, 2-way Wilkinson hybrid circuits are combined to deliver the input signal by providing a divided signal to each of the amplifier modules.  The output of each of the modules is combined by 2-way Wilkinson hybrid circuits to provide the amplified signal output.  In order to provide discrete power reduction switching from a full power condition to a reduced power condition, at least one of the inputs to a module is connected to a quarter-wave stub which is selectively grounded and open-circuited to reflect respectively an open circuit and a short circuit condition.  In this way, each amplifier module per-forms similarly in the reduced power output condition as well as in the full power output condition.

Abstract: EMERGENCY HYDRAULIC SYSTEM          ABSTRACT OF THE DISCLOSURE     An emergency hydraulic system for a vehicle having a hydraulic steering mechanism normally supplied by an engine driven pump. An electric motor driven pump supplies the steering mechanism under emer-gency conditions. The electric motor driven pump is inoperative during normal operation of the engine but if the engine ceases to operate it comes on responsively to the occurrence of a predetermined condition in the hydraulic circuit. In order to prevent the electric motor driven pump from operating during engine starting a relay is provided having a normally open switch in circuit with the motor.  The relay is operated by a normally open engine condition switch which is arranged to close when the engine is running.  The relay holds itself in, thus preparing the electric motor for operation should the predetermined condition occur in the hydraulic circuit of the steering mechanism.

Abstract: SYSTEM FOR DRIVING AC PLASMA DISPLAY PANEL         Abstract of the Disclosure An improvement to sustain drive circuitry for an AC plasma display panel wherein the sustainer signal applied to panel electrodes is simplified to comprise a sequential series of square waves. The actions of writing, selectively erasing and bulk erasing of light emissions in cells of the plasma panel are also performed by combinations of square wave signals generated in sustainer and driver circuits of the device.  A combination of integrated circuits comprise both the X and Y axis drivers with the Y axis drivers also including an internally generated Y axis sustain signal onto which Y axis write or erase signals are impressed.   The prior art requirement of floating supply voltages is removed and the number of supply voltages is decreased such that all driver and sustainer circuits utilize a common power source, with a maximum of three source voltage levels for operation of all sustainers, drivers, address inputs and logic and timing control of the circuitry.  The X axis sustainer may alternatively be comprised of a Mosfet circuit herein disclosed, including two high voltage high current Mosfet transistors connected in a totem pole fashion and operated in a manner which avoids simultaneous conduction of both transistors, thus reducing heat dissipation problems.
