The present invention is an Electric servo system which controls and automates gate openings based on GPS speed and position data that results in precise and reliable modern variable and constant rate application. The Electric servo system also allows for Mechanical gate linkages to remain intact, resulting in few changes to the aircraft and redundancy of emergency components. A Mechanical input connect/disconnect is used to effortlessly transfer between the automated Electric servo system and the Mechanical gate system.

A nested bushing arrangement is provided. The nested bushing arrangement may maximize bushing retention length in a narrow and/or small joint, and may offer anti-rotation features in the event that the nested bushing arrangement becomes loose. The nested bushing arrangement may comprise a first nested bushing coupled to a second nested bushing. Each nested bushing may comprise a mating aperture located opposite an annulus body. The annulus body of each nested bushing may insert within the mating aperture of the opposite nested bushing to couple the first nested bushing to the second nested bushing.

An actuator release mechanism comprising a longitudinal member, e.g. a piston, which is moveable axially to permit or prevent axial movement of the lock bolt and hence deployment of the actuator. Movement of the piston is due to the force of the lock bolt, under a spring force, on the one hand, and to the position and force of a linkage assembly on the other hand. The linkage assembly comprises a first link fixed, at one end, e.g. by means of a piston lock pin, to the piston and fixed at a pivot point to a second link. The second link is fixed to a rotational drive means, here a rotary solenoid or stepper motor, so as to rotate about a centre of rotation.

An apparatus, system, and method according to which a bellcrank is used to transfer an output of a lever to a component requiring actuation. For example, a bellcrank that includes two interlocking portions transfers an output of a linear motion around a fixed axis via a rotational motion then to a transverse motion in order to pressurize brake fluid in a master cylinder of a vehicle.

A chair adjusting device includes a control pull-bar including an elongate plate assembly formed of multiple elongate plates and a short plate assembly formed of multiple short plates. The elongate plates have a movement hole and a pivot hole opposite to the movement hole, and connecting protrusions at one side the pivot hole and connecting dimples on a back side of the connecting protrusions. Separator plates are interposed between the elongate plates and have combination projections receivable into the connecting dimples and combination notches on a back side and receiving the connecting protrusions therein. The short plates have engaging projections at one side thereof, and engaging troughs on a back side. Partition plates are interposed between every two pieces of the short plates. The partition plates have fitting bulges receivable into the engaging troughs and on a back side and receiving the engaging projections therein.
