Abstract: Water-gun Target Game and Apparatus in which a direct-current electrical water-presence detector, supported by or worn on an outer garment, is the bull's-eye. A hit by the water jet initiates action by a direct electrical effect, such as a resistance change, ordering responses by switching, sound or visual signaling, and scoring devices. A water-level sensor option initiates a steady signal after a succession of hits or a strong continuous hit. A single shunt option can be used to prevent false triggering. An absorption option disposes of received water, allowing repetitious operation. A tank for the water level sensor has a discharge stopper, which when removed, opens a power source circuit and inhibits any response. The object of the game is to project the jet stream of the water gun on to the target, making one or repetitious hits on the apparatus-bearer's bull's-eye. Counter-circuitry provides digital visual scoring.

Abstract: This is a swing-tower arrangement for coupling a back-hoe assembly to a tractor or the like. It features a rocker swingable in elevation on the swing tower. An actuator on the swing tower controls the position of the rocker, improving transport and control of the backhoe and making practical the adaptation of the arrangement to a wide range of tows. Detachable rockers are variously used to shift the backhoe assembly to transport and working positions and to tow and lift other types of subordinate machines. A power takeoff is mounted on the rocker.

It further relates to compound autogyros and/or helicopters that employ a lifting surface or wing in forward flight. More specifically this invention provides an autogyro with counter-rotating rotors, circular planform wing integral with the rotors, and means for engaging power to the rotors for vertical ascent, descent and hovering.

Abstract: A deburring method is presented wherein a cylindrical brush rotationally contacts the workpiece. The brush includes a mandrel having a central axle to provide support during use. To the mandrel is attached a multiplicity of long bristles. Each bristle is flexible and has impregnated therein a plurality of abrasive particles. The population density of the bristles on the brush is such that the outwardly extending ends can readily flex both in the plane of rotation and sidewise along the lengthwise dimension of the brush. Setting the brush so that the bristle ends overlap the surface of the workpiece being deburred, each bristle makes a slapping contact therewith. This results in one to two inches of each bristle being dragged endwise across the surface of the workpiece. The endwise movement of each bristle causes the abrasive particles imbedded therein to abrade the sharp edges of the workpiece. An automatic conveyor may be used to feed workpiece stock past the rotating brush at a predetermined rate.

Abstract: The time-to-go of the fuze of an artillery shell is digitally set after the round has been fired but before it leaves the muzzle of the gun. The communications link for setting the fuze includes a transmitting coil mounted on the gun muzzle and a receiving coil mounted on each shell round. The transmitting coil is energized with a plurality of signals on discrete frequencies. The output from the receiving coil is detected to derive one binary digit representing each discrete frequency. All the binary digits, "0" or "1", are simultaneously set into a binary counter in the fuze, so that the binary number represents the time-to-go.

Abstract: An infrared radiation suppressor secured to the discharge end of a gas turbine engine has a series of movable vanes maintained in an open trailing edge configuration in which they form converging flow passages for the gases emanating from the gas turbine engine and passing between the vanes, thereby decreasing the gas static pressure at the vane trailing edges below ambient levels. Flow passages in heat exchange relationship with the duct walls of the suppressor carry ambient air through the passages to a point downstream of the vanes. The lowered static pressure at this point causes ambient air to flow through the passages and into the gas stream, thereby cooling the duct walls and the gas stream. The hollow center of the movable vanes are also open to ambient air at the outer ends. The lowered static pressure at the vane trailing edges also causes large quantities of ambient air to enter into the hollow vanes and out the trailing edges into the gas stream further cooling the gases.

Abstract: The torque transmitted through a pair of helical gears mounted on a lay shaft imposes an axial force on the lay shaft which is reflected into fluid pressure to indicate the magnitude of the torque. By journaling the lay shaft within sleeves which are also the inner races of a pair of roller bearings its axial movements are sensitively transmitted to a nonrotating piston rod mounted in ball bearings within the bore of the lay shaft. The piston is displaceable into a cylinder supplied with pressurized lubricating fluid through a valve responsive to the axial displacenent of the piston. The fluid pressure in the cylinder balances the axial force transmitted to the piston and is proportional to the transmitted torque.

Abstract: Method of and apparatus for non-equilibrium chemical kinetic separation of deuterium from hydrogen are described wherein hydrogen with its normal abundance of deuterium and an appropriate reactant, bromine, are supplied to a deuterium reaction vessel wherein they are vibrationally excited by, for example, being exposed to a volumetrically scalable ionizing-sustainer electrical discharge effective to provide vibrational excitation of the H.sub.2 and HD following which selective intermolecular vibration-vibration energy pumping occurs giving conditions effective to produce an HBr/DBr product mixture. The ionizing-sustainer discharge is effective to generate vibrational excitation from which follows chemical reactions that produce DBr and HBr at such relative rates that the mixture is enhanced in deuterium content relative to said content of the entering hydrogen stream. For the production of heavy water, the DBr and HBr are then dissolved in water.

Abstract: A carbon ring seal for a shaft rotating at high speed is capable of preventing high temperature, high pressure gas from entering the oil system. The carbon seal is constructed so that at ambient temperature it works as a controlled gap seal, but when the seal runner reaches its full thermal growth the seal then functions as a positive contact seal. The carbon seal ring is not pinned against rotation, but rotation is limited by means of an integral drag pad. The seal housing is provided with a plurality of calibrated holes for predetermined internal pressurization and cooling.

Abstract: A forage harvester and attachment therefor are provided wherein such attachment serves the multiple purposes of cutting, conditioning, and selectively moving a crop in two basic directions from a crop transfer zone within the attachment, one of the directions being toward the ground and the other being away from the ground. The attachment comprises a flail device of predetermined width for cutting and conditioning a standing crop in one mode of operation and for picking up a pre-cut ground swath of a crop in another mode and moving that swath to the transfer zone. The attachment has an auger for gathering a crop into the transfer zone immediately after cutting to define a dense swath thereof which has a width less than that of the flail device and approximately equal to the width of the ground swath. The attachment has an additional auger and a door for selectively moving crop from the transfer zone in the above-mentioned two basic directions.
