Abstract: A manually actuated adjusting device for control valves of a hydraulic lift mechanism of a vehicle, especially of a fork lift truck, includes a shifting lever with an armrest supporting a lower arm which is connected with an adjusting mechanism arranged below the same and consisting of a guide joint and support elements. A formed-out support surface extends over the entire length of the lower arm which terminates at one end in an approximately vertical shifting lever that is formed-in into the armrest. Within the area of its transition to the support surface, the latter includes a trough-shaped recess formed out of the plane of the support surface.

Abstract: An actuating mechanism, for putting into operation a ram-air turbine of an aircraft, includes a slide member linearly moveable and connected with a Bowden cable which is actuatable in dependence on a blocking mechanism. In order that the actuating installation can be operated in a simple and safe manner, the blocking mechanism is connected with a hand lever which in the opened condition releases the blocking mechanism and cooperates with a support element of the slide member in such a manner that the slide member is adapted to be displaced into an end position by means of the hand lever.
