Abstract: ABSTRACT OF THE DISCLOSURE             A load handling device is disclosed having an improved swing drive assembly including a hydraulically driven pivotally mounted swing drive pinion biased against a segmented ring gear by a hydraulic actuator with a guide roller adjacent the pinion engaging a guide flange concentric with the ring gear to limit the maximum tooth engagement between the pinion and ring gear and thereby provide essentially constant backlash on the pinion gear regardless of eccentricities or other irregularities in the ring gear during swing drive operation.  When the swing drive pump is shut down a bypass valve is automatically actuated shunting the flow of hydraulic fluid around the pump and a spring operates to counteract the separating force between the pinion and ring gear due to wind induced rotating force which produces torque on the pinion as a result of the back pressure in the motor and the shunted supply-return lines.

Abstract: ABSTRACT OF THE DISCLOSURE           A drum rotatable about an axis through its center of gravity carries troughs located in a circle concentric to said axis and which are charged at a certain level with flowing mat-erial to be measured as to quantity, whereby the drum is influ-enced by a driving moment from the weight of the charged material.          After a certain rotation of the drum, the troughs discharge the charged material at a lower level than said charging revel.          Means are provided for counteracting rotation of the drum by said driving moment, said means including interconnected scoops arranged in a circle concentric to an axis through the common center of gravity of the scoops, said last axis forming an angle with a vertical line.  The drum rotates the scoops around said last-mentioned axis, and the scoops successively elevate a second material from a certain level and discharged it at a higher level.          The drum forms a closed chamber containing a certain amount of the second material, and the scoops are located on the inside of the drum within said chamber, whereby an accurate measurement of the weight of the flowing material is effected regardless of changes in the density of the material.

Abstract: ABSTRACT OF THE DISCLOSURE          A night visual aircraft system for receiving flight data from an aircraft simulator, and terrain data from the gaming area data base, includes a computer which organizes this image data by frame in a buffer memory according to a particular format of addresses, sequences, and bit places   The image data includes texture data for defining areas to be activated on the CRT such as runways, horizon glow, and faces of structures. An image processor receives the light source portion of the  formatted image data to translate the data into the aircraft coordinate system, rotate the data in accordance with the attitude of the aircraft, and project the data in two-dimension display coordinates.  A texture stage processes the texture portion of the data to activate face areas on the CRT display.   Texture data includes X and Y trace rates which are integrated to provide X and Y deflection ramp voltages.          The ramp voltages cause the electron beam to trace along the centerline of a face, and a deflection sinewave superimposed thereover fills out the area to be simulated.  Trace limit data 1- provided to terminate the display when the trace ramps exceed a predetermined value.   A range voltage ramp is generated from the Y deflection ramp and applied to the grid of the CRT to simulate range attenuation of intensity   Initial width and taper width data is provided to simulate distance attenuation of size.  Various compound signals may be applied to the deflection and intensity inputs to control the size, shape, shading, and perspective effect of the display.

Abstract: Abstract of the Disclosure A method for producing dry C1-C4 alkyl halides.          The method is characterized by reacting the corresponding alkanol with a 10% excess of hydrogen halide at elevated temperature and pressure, where the major portion of the water produced is in the liquid phase; the gaseous alkyl halide-hydrogen halide reaction product is contacted with alkyl halide-hydrogen halide liquid reflux, thereby drying the reaction product, and the alkyl halide is separated from the hydrogen halide.  The process avoids the use of sulfuric acid for drying, and results in the formation of only very small amounts of by-product dialkyl ether.

Abstract: ABSTRACT OF THE DISCLOSURE           A line circuit for a key telephone system using three relays, a line relay, a ring relay and a combined off-hook and hole relay.  To control the energization of the ring relay and the off-hook and hold relay responsive to inputs from the exchange or from a station of the line, an operational amplifier network is used.  Two amplifiers are used as individual relay drivers and two are used as comparators.  The amplifiers of this network  may be identi-cal circuits as part of a quad circuit chip.  On a ring signal from the exchange, a ring comparator amplifier is activated to energize the ring relay.  On a station of the line going off-hook, the off-hook driver amplifier is activated directly to energize its relay.  When a station of the line goes into hold, the off-hook and hold comparator amplifier is activated to energize both the ring relay and the off-hook relay.  The line relay is energized during only the ring and hold conditions, and is shunted against energiza-tion during the off-hook condition.  The hold condition is sensed by the line relay being energized, and the con-ventional A lead ground having been open-circuited.
