An implement coupling device (1) on a working machine (2) comprises a coupling means (11) provided with a first shaft (21); an engagement means (12) provided with a second shaft (22) arranged parallel to the first shaft (21); at least one linkage (13, 14) comprising a first portion (23, 24) connected to the first shaft (21) and second portion (25, 26) connected to the second shaft (22), which first and second portions are connected by a pivot joint (27); and a wedge (28) means arranged to be removably mounted between the first and second portions (23, 24; 25, 26), wherein the coupling means (11) and the engagement means (12) are displaceable relative to each other in a direction at right angles to the first and second shafts (21, 22) to attach or release the implement. At least one portion (23, 24; 25, 26) making up a linkage (13, 14) is detachably fixed to its respective shaft (21, 22) by a locking means (31, 32, 33, 34) in a longitudinal recess (41, 42, 43, 44) at right angles to the shaft (21, 22) and engaging with a tangential recess (51, 51, 51) in the outer surface of the shaft (21, 22).

An apparatus configured to structurally replace a cracked weld in a nuclear plant may include: a first body portion that includes a first gripping portion; a second body portion that includes a second gripping portion; a wedge portion between the first and second body portions; and/or an adjustment portion. The first body portion may be configured to slidably engage the second body portion. The wedge portion may be configured to exert force on the slidably engaged first and second body portions. The adjustment portion may be configured to increase or decrease the force exerted by the wedge portion on the slidably engaged first and second body portions. When the adjustment portion increases the force exerted by the wedge portion on the slidably engaged first and second body portions, a distance between the first and second gripping portions may decrease.

An adjustable assembly for a bicycle includes a first support having an interior surface and a second support slidably positioned within at least a portion of the first support. One of the first support and the second support is adapted to attach to a first bicycle portion, and the other of the first support and the second support is adapted to attach to a second bicycle portion. Further, the second support comprises an expansion portion configured to be moved between an expanded position and a retracted position. The expansion portion is configured to engage the interior surface of the first support when the expansion portion is in an expanded position. In addition, the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position.

A connector comprises first and second parts having first and second plates respectively. The plates can abut to cover a panel opening and have slots in their abutting edges. The second part has a portion which extends in the second plate slot and which extends beyond the second plate edge a distance defining a neck. An arcuate portion extends from an end of the neck to receive the cable and has a threaded terminal end portion. In a first orientation of the second part, the neck extends vertically below the first plate to allow ease of manipulation of the second part to receive the cable between the arcuate portion and the panel. In a second orientation thereof, the neck extends horizontally within the first plate slot when the second part is in a closed position with the terminal end portion received in an aperture in the first plate.

A lockable lateral adjuster mechanism comprises a platform with a channel carried by a base. A cam has an eccentric head that is pivotally disposed in the channel. The cam has a stem extending through the channel and into a counter bore in the base. The platform is laterally displaceable with respect to the base as the cam pivots. A countersunk interface is disposed between the eccentric head and the channel. A fastener extends through the cam to the base, and secures the cam, and thus the platform, to the base, and applies an axial load on the countersunk interface along an axis of rotation of the cam.

A connector for connecting a panel of a bridge platform or other scaffolding to an underlying cable for supporting the panel. First and second plates are hingedly joined. A member is attached to and extends from the first plate to a free end portion, wherein the member is adapted to be passed downwardly through a panel and cradle a cable passing below the panel then to be passed upwardly back through the opening then through an aperture in the second plate. A wedge is slidably receivable between ledges on the free end portion and the second plate for wedgedly retaining the member in the aperture. A member is attached to the second plate in a position such that it retains the wedge inseparable from the plates. The plates and wedge are inseparable from each other in each of latched and unlatched states.
