Abstract: This device for jettisoning a load in two completely different ways comprises a rocker fulcrumed on a support rigid with the load, or spherical member formed integrally with the support, and a pair of opposed hooks fulcrumed to the structure from which the load is to be suspended, these hooks being responsive to separate control members, so that when only one hook is retracted the load can be released. If a spherical member is used, sliding cylindrical members having opposed ends formed with spherical concavities matching the curvature of the spherical member are provided, so that retracting one or both sliding members will release the load.

Abstract: This automatic wedging device for operating each ejector of loads carried under an aircraft for jettisoning comprises at least one actuator of the cylinder-and-piston or worm-and-wheel type adapted to transmit a wedging force to a pair of symmetrical load-engaging wedging levers, and a device for automatically operating each actuator when the load is properly positioned in relation to the aircraft; other devices are provided for locking the wedging levers when this force has attained a predetermined value and restoring the wedging levers to their inoperative position after the load has been jettisoned as a consequence of the opening of the load suspension hooks.

Abstract: This hoisting device for loads to be carried under aircraft is incorporated partially or completely in a load carrier system without requiring any lateral access, the connection between the hoisting device and the load being eliminated automatically once the load is properly anchored to the carrier system. The device comprises one or two ropes, as the case may be, and comprises an anchoring member rigid with the load and formed with an internal groove engageable by a set of balls carried by a socket in which an end piece crimped to the rope end is adapted to travel axially through a limited extent. Slackening the rope will free the load which is then retained by the carrier system.

Abstract: This device for automatically and releasably hanging and holding loads carried under aircraft against lateral oscillation incorporates a push member and a ball and socket of which the line of action with respect to the load is directed slightly outside the transverse dimension of the associated bridge member engaged by substantially triangular sockets of the ball and socket to prevent any lateral oscillation of the load under centrifugal or transverse aerodynamic or inertia forces.

Abstract: In a telescopic retractable ejector, the driving gas is allowed to flow freely with the maximum efficiency by compensating the pressure drop resulting from the gas expansion during the piston extension with a concomitant and automatic increment in the surface area of the pistons which is exposed to the gas pressure.

Abstract: Device for memorizing the position of a counting system in case of failure or cut-off in the supply current characterized by the combination of a magnetic doughnut with each output of said counter, said doughnut being adapted to be energized by a pair of windings supplied with current under the control of the associated counter output so as to assume one or the other of two states according to the momentary state of the associated counter output, said doughnut further comprising a third winding delivering or not, when the supply current is restored, a pulse utilized for restoring the counter to the state it had when the cut-off took place.

Abstract: This device for automatically releasably hanging and holding against lateral oscillation load carried under aircrafts has load suspension hooks and holding members preventing the lateral oscillation of the load which project very moderately from the underface of a closed casing containing the actuating mechanism. This mechanism includes in combination linkage detents and springloaded devices disposed on either side of each load suspension hook. A certain delay is introduced into the action whereby when the load is lifted for engagement with the hooks, these are actuated to their load-supporting position and release with a predetermined time-lag the linkage holding the load against lateral oscillation to their operative position. To this end, each pivotally mounted hook is connected via a spring-loaded piston-and-cylinder actuator to a rocker controlling the movement of wedge members controlling in turn a lever supporting the holding members.

Abstract: This device for the remote transmission of a plurality of orders through a single control line or channel is intended more particularly for controlling the firing rates and volley-firing limitation of rockets or miscellaneous cartridges notably on aircraft. It comprises essentially a selector-switch control unit and a receiver unit. The device is energized from the common direct-current supply of the aircraft.
