A buckle member having a pair of apertures is mounted on the retaining ring such that each tab passes through a respective aperture and the buckle functions to maintain the terminal ends of the retaining ring in a specific orientation when it is mounted on a wheel rim. A wire fastener is positioned through each drilled bore in a tab to retain the buckle member on the split retaining ring.

Abstract: A cartridge launched spin stabilized disk for deploying chaff (radar countermeasure dipoles) or other expendable materials or substances from a moving aircraft. The disk, containing the expendable material is ejected from the aircraft at some elevation angle and at an angle in azimuth off of the aircraft line-of-flight and dispenses the expendable material in a more or less uniform fashion for a brief period of time as it travels away from the aircraft.

Abstract: An airborne spin dispensing apparatus (100,101) and method of dispensing a plurality of sub-units (60) such that the ground plane impact pattern of the plurality of sub-units substantially corresponds to a particular geometric ground target. An onboard microprocessor (24) which receives flight data (26) and a selected target data (28) also has a program store of sub-unit ejection sequences each of which corresponds to a particular target impact geometry. The microprocessor (24) selects an appropriate sub-unit ejection sequence in accordance with the flight and selected target data and effects a release of the sub-units (60) from the spinning apparatus such that their ground impact pattern substantially matches the geometry of the ground target.

The payload disk has tapered bore wall surfaces which confine the payload material and upon being ejected the spin-stabilized payload disk disperses the payload substantially uniformly within the first few milliseconds after leaving the cartridge case.

Abstract: A long beam having designated forward and rearward ends includes a mounted load trolley for carrying and moving a load along a portion of its length, which beam is adapted for being carried aloft in a substantially horizontal attitude by a high lift crane. The beam also carries a standing leg apparatus at its forward end and the load is carried by the trolley from a rearward stopped position that is axially aligned with the center of gravity of the apparatus to a forward off-loading position. The trolley is maintained at the rearward center of gravity position while the high lift crane carries the apparatus and the load aloft to a delivery location and the standing leg apparatus is lowered to a substantially vertical position with respect to the horizontal attitude of the beam to take the weight of the load when the trolley is moved off of the center of gravity position for delivery and off-loading of the load at the forward end of the beam.

Abstract: A flexible and collapsible storage tank (10) for holding large volumes of material is fabricated in a rectangular shape from long lengths of a rubberized square-woven fabric. The lengths of fabric are oriented with overlapping adjacent edges to form inner (122) and outer (124) envelope structures which are integrally vulcanized into a homogeneous tank body (20). The inner envelope (122) is formed by longitudinally oriented fabric plies (22) having overlapping adjacent edges (22a) while the outer envelope (124) is formed by edge plies of fabric (26) folded about the peripheral edges of the inner envelope (122) and orthogonally oriented fabric plies (24) positioned on either side of the inner envelope (122). The tank (10) includes an air vent valve (40) mounted in its top and a closure (30) which clamps and seals a corner exposure (20a) of the tank body (20) and provides access and communication into the tank for filling and emptying.

Abstract: A control circuit for regulating the application and release of brake force in an electric brake. A pulse width modulator presents an output signal of regulatable duty cycle to power drivers connected to the electric motors of the brake. A control circuit regulates the direction of current flow through the motors to achieve either brake application or brake release. The output of the pulse width modulator is set by the position of the brake pedal or by a signal which is a function of the correlation betwen brake torque and the position of the brake pedal, whichever is larger.

Abstract: A device (10) for venting aircraft tires comprises a fusible plug (42) and a spring-biased piston (30), both plug (42) and piston (30) being positioned within a single bore (B) of the device. The plug (42) is meltable out of the bore when the wheel (12) temperature increases above a specific limit set by the eutectic material which frees the piston (30) to move out of a spring-biased and bore-sealing position within a sealing ring (22) by an overpressure within the tire which overcomes the spring bias. The piston (30) will return to a sealing position when the pressure drops below a value which is insufficient to overcome the spring bias.
