A movable handle includes a movable member and a seat, both of which can be made of a plastic, a metal or a composite material. The movable member includes a main body and a bent portion. The main body can be bar-shaped, block-like, ball-shaped, wedge-shaped or in any other suitable shape, and the bent portion can be bent inward, outward or in any other direction relative to the main body. The main body of the movable member is movably assembled to the seat, and the seat is connected to a first object, such that the movable member is indirectly connected to the first object via the seat and can be turned or moved upward and downward or leftward and rightward on and relative to the first object.

An actuating element for actuating an instrument for performing minimally invasive interventions comprises a first handle half-shell and a second handle half-shell movable relative to each other and connected with each other at one end by a biasing mechanism; a tube arranged substantially centrally between the handle half-shells; a linkage mechanism arranged between the handle half-shells and the tube in order to transmit an actuating movement of the handle half-shells; a locking mechanism with a latching rocker arranged on the first handle half-shell and a locking rocker arranged on the second handle half-shell, wherein the two rockers enter into locking connection with each other through an opening provided therefor in the tube when the handle half-shells are moved together, and wherein the rockers are mounted around a pivot axis such that a swiveling or pivoting movement of the rockers lies within a plane defined by the handle half-shells.

In a drive arrangement for the loading arms (5) of a loading ramp for a heading machine or longwall shearing machine, each loading arm (5) is rotatably supported in off-center position on a rotary disc (7) and extended beyond its axis of rotation (6) by guide arm (10) arranged so as to swivel around a bearing point on one end of a steering lever (11). The heading machine or longwall shearing machine has--for broadening its loading ramp--laterally outwardly swivellable parts (2) having arranged thereon, in a manner preventing angular movement, an arm (14) extending beyond the pivotal axis (4) of the extendible part (2). For automatic adaptation of the removal width of the loading arms (5) to the selected working width of the loading ramp, the other end of the steering lever (11) is hinged to the free end of the arm (14) connected with the outwardly swivellable part (2).

A vehicle gearshift selection system for a multiple-speed power-assisted transmission having a gearshift lever which is shiftable into a single shift-up position or a single shift-down position. A gear sensor for monitoring the position of the gearshift lever and connected to an evaluation control circuit. The electronic evaluation control circuit is connected to the multiple-speed power-assisted transmission and receives signals concerning the prevailing driving conditions of the vehicle for engaging an optimum higher gear when the gearshift lever is shifted-up and for engaging an optimum lower gear when the gearshift lever is shifted-down.

An electric device for adjusting the angle of reflection of a mirror mounted on a motor vehicle. The mirror is pivotally connected to an actuator unit housing containing two actuators. Two adjusting nuts each having a movable pivot are respectively moved forward or backward by their actuators so as to adjust the angle of the mirror. The device of the invention is characterized by having a first guide means and/or a second guide means for controlling the direction of inclination, horizontal or vertical, of the mirror so as to prevent the mirror from being obliquely displaced during the operation of the motor vehicle. The first guide means comprises a cross-shaped member provided in front of the actuator unit housing and a cross-shaped groove, engaging therewith, provided on a mirror holder. Alternatively, the first guide means may comprise a cross pin, one of the two axes thereof being supported on the actuator unit housing, the other axis thereof being supported on the mirror holder. The second guide means comprises openings, longer in the horizontal or vertical direction, into which the adjusting nuts are respectively inserted.

The hand drive employs two coil springs between the sleeve of the coupling and the shaft to be turned. The hand wheel has a driver with a parallelepiped extension for abutting one or the other of the facing spring ends depending on the direction of rotation of the hand wheel. A brake is also used to restrain movement of the sleeve and limit the torque exerted on the sleeve by the hand wheel.

An improvement in a linkage assembly which comprises a bellcrank pivotally mounted on a stationary shaft. The improvement comprises first screw threads on the stationary shaft and second screw threads on the bellcrank mating with the first screw threads to form the pivotal mounting of the bellcrank to the stationary shaft while substantially preventing axial motion of the bellcrank relative to the stationary shaft in the absence of relative flotation therebetween. Any play or looseness in the motion of the bellcrank is thereby substantially eliminated.

An actuating mechanism for selectively actuating the control valve of a transmission or the like comprises a rotary input shaft connected to a pair of links at a lost-motion connection. Opposite ends of the links are pivotally connected to a crank assembly pivotally mounted on a rotary input shaft connected to the control valve. A torsion spring is interconnected between the rotary output shaft, the crank assembly and one of the links to selectively rotate the rotary output shaft in opposite directions in response to rotation of the rotary input shaft in opposite directions.
