A self-locking connection device is provided, which includes a housing, a sliding block and a buckle which are mounted in the housing. The sliding block slides back and forth along the housing and is locked in case that the sliding block is pushed to a front side, and is unlocked and reset in case that the sliding block is pushed to the front side again. An inclined wall for supporting the buckle is provided inside the housing, a height of the inclined wall gradually decreases from front to rear, the buckle is connected to the sliding block to move along the inclined wall with the sliding block, and the buckle is locked at a top end and protrudes out of the opening in case that the sliding block is locked at the front side.

A connection system for a hot gas-conducting annular duct of a turbine intermediate casing of a gas turbine includes a first housing element, a second housing element situated next to the first housing element in the circumferential direction, and a fastening unit configured for connecting the first housing element and the second housing element to one another at edges adjacent to one another in the circumferential direction, the fastening unit including a clamping element which is mounted on the one housing element with the aid of a connection, the clamping element resting on a clamping surface provided on the other housing element in such a way that the other housing element is accommodated between the clamping element and the one housing element. It is provided that the top side of the clamping surface facing the clamping element has a clamping surface contour—relative to a longitudinal section which extends along, in particular essentially in parallel to the adjacent edges of the two housing elements—which is designed in such a way that it thwarts a rotation of the clamping element about an axis of the connection.

A rectangular stage includes a deck supported by a frame and removable legs. The legs insert into a corner receiving assembly below the stage deck at each corner. The leg receiving assembly includes a cylindrical socket into which the top of the leg inserts. The leg receiving assembly also includes a retaining linkage that extends through a slot in the side of the socket and engages the leg. The retaining linkage also includes a manually actuatable latch coupled to the cam to maintain the cam in engagement with the leg.

A traction sheave clamping device for detachably fixing ropes to the traction sheave of a Koepe hoist, having at least one clamp crossbeam, at least two anchoring elements for engaging in wedge-shaped or hook-shaped grooves in the face sides of the traction sheave/cable chuck rim sheets, and stud bolts for connecting the anchoring elements to the clamp crossbeam, wherein the anchoring elements and the traction sheaves have corresponding torque support surfaces extending substantially in the pull direction of the stud bolts, wherein the extension of the torque support surfaces in the pull direction of the stud bolts is a multiple of the distance between the stud bolt center axis and the anchoring point.

A new system and apparatus for detachably joining a first component to a second component is disclosed, along with a method for detachably joining two components. Embodiments of the present invention include a tensioning apparatus and system for clamping joints. The tensioning apparatus may include a wedge block and a fastening device. The clamping joint may be a tongue and groove joint that is tightened using the tensioning apparatus.

A tool mounting assembly comprising a shank holder having an elongated passage and an elongated tool shank for an earth working or agricultural tool which is received within the passage and which includes a series of longitudinally spaced teeth. A rotatable adjuster is mounted on the shank holder and can cooperate with the teeth for moving the shank longitudinally of the passage to vary the operating depth of the tool. The shank can also cooperate with the adjuster to lock the adjuster against rotation which prevents longitudinal movement of the shank. A retaining member can be located in the passage for cooperation with the shank to hold the shank in this position. The adjuster may also be rotated to a position out of engagement with the shank teeth which allows for longitudinal sliding movement of the shank through the passage.

An adapter for anchoring an object to an existing support structure comprises: a securing block comprising a first inner block, a second inner block complementary to the first inner block, the first and second inner blocks defining a channel therethrough when placed in opposition for receiving and securing to the existing support structure, the first inner block comprising a first securing means and the second inner block comprising a second securing means; and an outer sleeve for coupling to the securing block, having: an opening to receive the existing support structure; a sleeve channel for receiving the securing block; and an attachment arm attached to an outer surface of the outer sleeve for anchoring the object.

Slip joint clamps seat on a diffuser end via external features of the diffuser, like guide ears, regardless of slip joint wear or damage. The clamps can be opened and closed to surround an inlet mixer forming a slip joint with the diffuser without disassembly. Slip joint clamps drive or bias the inlet mixer in a lateral direction largely perpendicular to the axial orientation and end of the diffuser to achieve a desired preload force in the inlet mixer and clamp connection. Clamp arms include rotatable halves that, when joined, form a complete fill between an inner surface of the diffuser and outer surface of the inlet mixer. A lateral drive pushes the inlet mixer against the clamp and may include a resistive element. An accessible set of guide ear bolts and lateral driving bolts permit exterior manipulation to axially mount or laterally bias the clamp in the slip joint.
