Abstract: ABSTRACT OF THE DISCLOSURE      A light system providing a visual indicator arrangement that is visible to an aircraft pilot to provide guidance during a runway approach segment and landing segment of the flight path of an aircraft.  The system includes lighted indicators which define two inclined plane surfaces, the intersection of which forms a straight line which is precisely the correct path for the aircraft to follow in making its approach to the runway with the indicators being so arranged as to form lines which appear to the pilot to converge and intersect at an aiming point on the runway even though the point on the runway is not yet visible.  Additionally, the system includes a landing segment for providing guidance for flare-out and actual touch down which includes lighted indicators at predetermined intervals alongside at least one side of the runway with the indicators defining a number of plane surfaces each of which intersect a longitudinal vertical plane passing through the run-way center line so as to form or define a precise landing path for the eyes of the pilot.

Abstract: ABSTRACT         The invention relates to a hose feeding winch speci-fically intended for use in the charging of drill-holes with pulverulent or pumpable explosives through a hose inserted into each individual drill-hole. In the charging of drill-holes especially in rock chambers with narrow spaces the required quick charging of many drill-holes formed in the walls and roofs of the chambers involves many different operational steps for storing the hose by winding up the same on the winch, connecting its rear end to a source of explosives introducing its front end with great accuracity into the individual hole and retracting the same from the hole with the same speed as the explosive is discharged from the front end of the hose and fills the hole for thereupon in wound-up position being ready for a repeated cycle of operations. The winch constructed according to the in-vention which is capable of quickly and accurately performing all steps of the cycle is mounted on a truck and substantially comprises three main parts: a drum rotatable about a central shaft, a drum cage enclosing said drum and mounted separately rotatable about said central shaft and a cradle supporting the central shaft and mounted rotatably about a central axis on the platform of the truck. The drum is devised with means forming a channel or path for the charging hose to be wound up and unwound in a  single layer without displacement by sliding movement in radial or peripheral direction on the jacket surface of the drum. The cradle carries on its top an extension unit adapted to be elevated relatively to the cradle and substantially consisting of two profiled parts longitudinally slidable the one within the other and a nose device swingably attached to the discharge end of the extension unit and equipped with means for guiding the hose from the drum to the central shaft and from there along the extension unit and means for aligning the discharge or front end of the hose projecting from the nose device to the axis of the drill-hole to be charged with explosive. The truck carries vehicles in which various explosives are stored and from which branch pipes open into a fixed hose pipe which is connectable to the charging hose.  By rotation of the drum the hose is guided along the channel about the drum and fed through the extension unit and the nose device into the drill-hole in alignment with the nose device to be retracted by reversed rotation of the drum with the same speed as the drill-hole in consideration is being filled with explosive. The winch according to the ivention also comprises power means for adjusting the individual parts relatively one another according to commands from two control pulpits arranged so on the truck platform as to be easily accessible to an operator standing on the ground immediately behind the rear end of the truck.

Abstract: ABSTRACT         A shaking table sorter has an inclined slotted sorting plate upon which separation of stones and the like from grain is made under the reciprocative oscillation of the plate and under the action of an air current the bulk of which flows through the plate in parallel with the direction of oscillation.  An air flow of more uniform strength is obtained by circulating the air through a wind barrel extending between an outlet beneath the plate and a suction inlet, by means of a nlower in the barrel, the blower, the inlet and the outlet all extending across the width of the barrel.      The sorting plate is preferably slotted by slitting and expanding its material to produce appropriately oriented slots, groups of slots close to the upper end of the plate being oriented so as to direct stones into and reject grain from an outlet chute for stones.

Abstract: ADDITIVE METERING SYSTEM USING A                    CENTRIFUGAL PUMP         ABSTRACT OF THE DISCLOSURE       A novel system for metering a relatively viscous fluid into a less viscous fluid using a centrifugal pump is described.       In particular, a novel valve for use in the system including a fluid pressure responsive means to actuate a needle valve which is slideable into an orifice for control or metering of the viscous fluid is described.  The valve meters decreasing small amounts of the viscous fluid in direct relation to the increased pressure developed at the delivery end of the centrifugal pump because of the selection of the angle of the point of the needle and its relationship to the orifice.  The system is particularly adapted to metering viscous polymer containing fluids, including microdispersions of polymers as solutions or true solutions into water in very small amounts thereby reducing friction and increas-ing fluid flow in delivery conduits such as fire hoses and the like.
