Abstract: ABSTRACT OF THE DISCLOSURE         An improved microfiche reader-printer includes an electro-mechanical control mechanism, roll paper storage and feed mechanism, paper cutter and a corona paper charger unit in the upper portion of the machine.  Disposed in the lower portion of the machine are a paper developer, dryer and dis-charge chute, a light source, microfiche carrier and an opti-cal lens system.  The optical system includes two moveably disposed mirrors selectively operable to project one selected fiche image either forwardly onto a viewing screen or rear-wardly to an exposure station where a selected size paper is momentarily retained to permit exposure.  The control mech-anism functions to effect sequential operation of each of the machine elements whereby a selected fiche image is read and printed.  The paper cutter includes a unique cutting bar mounting arrangement which includes means for allowing pivot-able movement at one end and horizontal movement only at the other end of the cutting bar to maintain it in contact with a rotary blade cam surface to provide proper cutting blade-cutting bar overlap notwithstanding external torsional forces applied to the paper cutting mechanism.  The corona paper charging unit includes unique corona wire support means affording a corona structure of simple construction while assuring proper corona wire tension and insulation.

Abstract: A B S T R A C T         The invention relates to internal combustion en-gines of the reciprocal type, and more particularly to such engines in which the pressure for Diesel operation can be attained, or in which the power output of an Otto-cycle engine can be increased.         The present invention makes possible either a Diesel engine of approximately the same axial crank offset and overall dimensions as an Otto-engine of equal throughput, or an Otto-engine having a higher throughput with slightly increased overall size and axial crank offset.         The  said gas supplies are impelled by two pressure impellers which are synchronized to engine operation, a vertical pressure impeller receives a fuel-air mixture and the inverted pressure impeller receives air, a rotary meter-ing pressure booster meters an amount of the fuel-air mixture and forces it under pressure into a pressure retaining cham-ber above the cylinder chamber ready to be released upon demand.         A second  metering pressure booster supply-ing auxiliary air acts to scavenge and cool the cylinders at the end of each power stroke, as the fuel-air mixture is released from the pressure retaining chamber into cylinder chamber, and as engine speed increases an increasing amount of the auxiliary air will be trapped in the cylinder chamber and compressed together with the fuel-air mixture gradually raising the initial compression as it is compressed into the combustion chamber where it is ignited.

Abstract: ABSTRACT OF THE DISCLOSURE      In a hot chamber method of pore-free die casting in which a reactive gas flushes non-reactive gas such as air from a die before a material is cast therein, the material displaces non-reactive gas from the gooseneck and nozzle through which the die is filled before the reactive gas flushes the die.  The material then does not push non-reactive gas into the die as it fills the die.  Apparatus for practicing the method comprises servo-control means for filling the gooseneck and nozzle with the material before the reactive gas flushes the die to displace non-reactive gas therefrom and then filling the die with the material after the reactive gas has flushed the die.

The device includes a rotor shaped like a disc and secured to a shaft about which it rotates.  Provided in the rotor are a plurality of piston chambers extending from the outer circumferential surface inwardly at an angle to a radiant from the axis.  Each of the chambers opens through both side walls of the rotor, and each contains a piston.  Each of the pistons is pivoted on either side to an arcuate drive segment adapted to move around an annular recessed channel within structure which defines a stationary enclosure for the rotor.  There are two annular recessed channels, one on either side of the rotor, and the channels are aligned with each other and eccentrically located with respect to the axis of the rotor.  With this arrangement, rotation of the rotor within the stationary enclosure is simultaneous with reciprocatory movement of the pistons in their respective piston chambers.  Passageway and port means are provided in the apparatus for allowing an interchange between rotary energy and fluid pressure energy.

Abstract: SKIN MELTING     ABSTRACT OF THE DISCLOSURE    A surface treatment for a class of metallic articles is described.  The treatment involves the melting of a thin surface layer of the article by a concentrated energy source, within a narrow set of parameters.  The melting step is performed in a manner which maximizes the temperature gradient between the melted and unmelted portion of the article, consequently, cooling and solidification upon the removal of the energy source is extremely rapid and can produce unique microstructures.          The preferred energy source is a continuous wave laser, and in the preferred embodiment, a flowing inert gas cover is used to minimize melt contamination and plasma formation.  The technique may be used to produce amorphous surface layers in a specific class of eutectic alloys.  In another class of alloys, based on the transition metals and containing precipitates rich in one or more metalloids, uniquely fine microstructures may be produced.
