A rotor of a wind turbine is disclosed with a pitch system locking arrangement to lock the position of a wind turbine rotor blade. A rotor comprises a rotor hub and a rotor blade, whereby the rotor blade is connected to the hub via a bearing, to be rotatable in respect to the hub in a pitch movement. The rotor blade comprises a root section, and the root section comprises a plate, that at least partially covers the cross section of the rotor blade. A certain predetermined rotational position of the rotor blade with respect to the hub is a locked position. The hub includes a locking pawl. The plate comprises an opening, and the locking pawl is at least partially located in the opening of the plate, when the rotor blade is in the locked position.

A clamp for headwear and other objects. The clamp includes a movable arm pivotably coupled to a fixed arm, which is coupleable to a surface. An object can be inserted into the gap between the lower ends of the two arms. A spreader element in an extended position maintains the lower ends of the arms spread apart. A spring exerts a force on the upper ends of the arms so as to push the lower ends of the arms together. Insertion of an object into the gap moves the spreader into a withdrawn position, allowing the lower ends of the arms to grip the object. Pushing the upper ends of the arms together releases the object and replaces the spreader element in the extended position.

A clamping device (100) includes a first movable member (210) that is movable along an extending direction of a first body interior space (120), a disc spring (260), an annular spring (270), a spring (280) and a collet (300). A driving mechanism (400) has a second movable member (430) that moves along an extending direction of a second body interior space (130) with rotation of a rotary member (410). When the rotary member is rotated in one direction, the first movable member moves toward an oil-filled closed space (121) and the clamping device is set to a clamping mode that will hold a tool holder (510). On the other hand, when the rotary member is rotated in the opposite direction, the first movable member moves towards the side opposite of the oil-filled closed space and the clamping device is set to an unclamping mode that will release the tool holder.

The invention relates to a force generator for generating a linear pressure force, including a housing, an output wedge displaceably arranged in the housing, and a drive wedge for transmitting an externally exerted pressing force into a linear movement of the output wedge. The output wedge is connected to a first pressure element. The housing is connected to a second pressure element. A force applied to the drive wedge causes displacement of the first pressure element relative to the second pressure element. The force generator solves the technical problem of providing a high pressure force and using the known press jaws for this purpose.
