Abstract: A balance weight supported by a spring clip is inserted inside the low turbine shaft of a jet engine at the proper position and frictionally engages an inner bulkhead in the form of an "anti-oval plug". The clip is provided with a threaded opening to receive the threaded end of an elongated rod whereby the clip is inserted within the shaft and installed at the desired location after which the rod is unscrewed from the clip and withdrawn, leaving the weight in place on the anti-oval plug.

Abstract: A lighting system for selectively back lighting a translucent object, or preselected portions thereof.

Abstract: An instrument for sampling both solid and liquid water particles in the atmosphere and continuously producing an electrical output response directly equivalent to the total percentage water content of the atmosphere sampled. The solid and/or liquid water particles are collected by using a large funnel shaped scoop of 100 cm.sup.2 to allow high volume collection at nominal aircraft speeds. The water is routed into the detection device which includes a concentric cylinder flow-through capacitor that varies in capacitance according to the dielectric of the fluid enclosed.

Abstract: The pattern of the flow of a gas that is injected into a gaseous stream is made visible by causing the flow of the injected gas to become luminous; and, therefore, to be visible, detectable, and recordable. This luminosity is accomplished by producing long-lifetime (metastable), excited-state species (atoms or molecules) of the main gas flow upstream of the injected gas.

Abstract: An air-flow actuated power supply and switch device having a pop-up cover which includes an air scoop, a switch actuator mechanism and an interface cable as a part thereof. The power supply is activated by pulling a lanyard which causes the pop-up cover to rise and expose an air scoop causing electrical energy to be generated for operating an electric bomb fuze or the like. A breakaway coaxial cable incorporated in the device permits the injection of electrical signals from the aircraft to the fuze system by a radiation hazard detection system.

Abstract: A hand tool for aiding in the removal of heavier, steel type staples normally used for binding a relatively large number of pages together including a handle with a steel tube having a uniquely shaped working end extending therefrom to allow it to be inserted under the bent end portions of a U-shaped clinched staple and pivoted upward causing bent portions of the staple to straighten thereby allowing the stapled work to be more easily separated.

Abstract: A sensor system that measures flight motions with respect to a classical Euler angle system of coordinates by aligning itself with the plane of total angle of attack via a pendulum mass. The system permits a simple determination of lift and drag for a spinning vehicle at angle of attack whereby the measurements are used as inputs to a flight control system to control the motions of the spinning vehicle.

Abstract: A hydraulically actuated collet type grip with an elastic support structure to allow for the axial bending needed to compensate for diametral dimension changes in the specimen gage section to be accomodated within the grip rather than within the tubular specimen. The tabbed end of the tubular specimen is gripped in the annular region of the loud transfer section of the collet. Load transfer is achieved by normal pressure on the collet and the frictional interface between the collet and the bonded end tabs on the specimen.

Abstract: An adjustable self-aligning locator for supporting a plurality of parts in their proper relative position for assembly and/or clamping to a machine bed and the like. The locator includes a support member having a base leg with a cam locking device for engagement with a T-slot on the machine bed and an upright leg with a side extension portion having an arcuate groove therein. An angle member having a matching arcuate shaped protuberance at one end in engagement with the arcuate groove in the upright leg extension provides an adjustable angle working face for contact with the workpiece.

Abstract: The mechanism accurately removes rounds of ammunition from a moving horizontal conveyor and places them into a stationary partitioned tray which is disposed below both the inventive mechanism and the conveyor. The mechanism comprises two counter-rotating dump bars driven by an indexing drive assembly which, in turn, comprises a combination of geneva-type indexing drive units and conventional gearing. The indexing drive assembly provides the dump bars with a 16-to-1 dwell-to-drive ratio, and rotates the bars 90.degree. each actuation. The dump bars have guiding surfaces across which the rounds of ammunition are moved by elements of the horizontal conveyor, while the dump bars are in the locked dwell position. When the dump bars are full of rounds, the bars index and transfer the rounds out of the conveyor elements and into the tray for subsequent operations, without interaction with, or interference by, the conveyor.

Abstract: A tool for removing "frozen" jammed or difficult to remove screws especially in hard to reach areas where adequate pressure on the screwdriver cannot be applied. The tool is a second class lever wherein the fulcrum is a threaded member with matching threads inserted in an empty screw hole at one end and the lever extends to a pivotable handle at the other end. Intermediate the ends is a sliding block to support a screwdriver blade, socket extension and ratchet handle for turning out the jammed screw.

Abstract: A caseless round adapted for use as a high velocity armor piercing round which, in turn, is ideally suited for use by aircraft in air-to-air and air-to-ground modes.

Abstract: A reusable shipping container assembly for securing, supporting, housing and shipping items. In a preferred embodiment, the container assembly includes: (a) members for securing and supporting the item, including: a slotted base upon which the item is placed; a plurality of removable straps, with fasteners, passing through any two of the slots, for strapping the item to the base; a plurality of bracing blocks, movable on the base and releasably lockable in the slots, to abut and brace the item; and a floor, removably positioned under, and also cushioned under, the base; and, (b) a completely closeable container for housing the item to be shipped, and the members of the assembly which secure and support the item to be shipped. This container assembly, unlike the prior art not only is reusable, but also permits the simultaneous housing and shipping, within the same container, or a multiplicity of items that vary in size, shape, and weight.

Abstract: The antinarcissus reflector assembly comprises: a cold stop subassembly that includes an aperture; and a concave spherical mirror having an opening, and also having a center of curvature at the center of the aperture of the cold stop subassembly. Unlike in the prior art devices, the only cold surface that is seen by the optics ahead of the detector is the face portion thereof, which shows through the opening in the concave spherical mirror, rather than reflections of the interior of the cold stop subassembly. Therefore, the undesirable diffused, cool patch which appears in the center of the picture when prior art devices are used is eliminated or, at the very least, is minimized.

Abstract: An overload release clutch having a driving rotor mounted on an input shaft and a driven disk mounted on an output shaft. A shuttle rotor having saw-tooth shaped teeth on its perimeter rides on a splined hub which is an integral part of the driving rotor and engages complementary teeth on the perimeter of the driven disk. Laminated leaf springs are held in position by means of rocker bars which insure that no portion of the torque is transmitted through the leaf springs. In the buckled state, the leaf springs exert a compressive force against the shuttle rotor to maintain it in full mesh with the driven disk during the engagement cycle. Disengagement occurs when a sudden increase in torque in the output shaft causes the driven disk to rotate and force the shuttle rotor axially upward until the buckled leaf springs snap "overcenter" and hold the two toothed members apart.

Abstract: An internally threaded igniter tube is threadably attached to a boss on the projectile base. In order to withstand ramming, a diametral flange at the base of the round engages a shoulder on the propellant so that when the igniter is in the assembled position, the midsection area is loaded in tension while the forward threaded section is loaded in shear. This arrangement produces superior ballistic properties by permitting the ballistic shot-start to be low enough to insure early motion while at the same time having the ability to withstand relatively high impact loads.

Abstract: A bellcrank assembly, adapted for mounting on, and actuating, a convergent flap of the exhaust nozzle of a turbojet engine. The unique structure of the assembly, unlike the prior art, transmits radial and bi-directional thrust loads to the flap utilizing low cost stamped and formed sheetmetal components, with the loads being transmitted directly into the skin of the flap. The bellcrank assembly is structured for external mounting on the convergent flap, thereby permitting easy inspection, maintenance and service, without the need to disassemble other nozzle hardware; and, it includes angular contact bearings with cross-corner path arrangement, and bellcrank link arms and a bellcrank actuator arm which actually physically comprise the housing of the bellcrank.

Abstract: A cloud detonation initiator on a fuel-air-explosive (FAE) weapon in the form of a high-explosive retrolauncher attached thereto wherein a plurality of gun tubes each deploy an explosive grenade rearwardly to compensate for the forward motion of the FAE weapon. The grenades are essentially stopped in space as the cloud forms around them. The retrolauncher includes a plurality of different size charges in operative communication with a single chamber so that the velocity of the grenades can be controlled within a predetermined range by selectively detonating the charges singly and in combination.

Abstract: A laser which obtains lasing action from gases flowing into and out of a laser cavity is substantially improved by causing the flowing gases to traverse a strongly recirculating flow field. The recirculation of exhaust flow gases into the incoming flow gases, in a controlled recirculation region, leads to substantially uniform distribution of gas composition, chemical and thermodynamic states, pressure, temperature, density and refractive index throughout the cavity. Recirculation flow fields are generated by opposed jets, behind baffles, in swirling flow, in spheres when jet velocities are high and in duct flows where a high momentum, high velocity jet is surrounded by a co-flowing low momentum low velocity stream.

Abstract: A variable position launcher including a launch tube in which the second event (SE) package is placed. A positioning spring on the explosive side of the SE package urges it toward the muzzle end of the tube which is sealed with a frangible cover. A gas inlet operates to pressurize the muzzle end of the tube and apply a velocity dependent force on the SE package opposite the spring force so that the SE package is accurately positioned within the tube thereby controlling the retrolaunch velocity.
