Disclosed is a coupling assembly for joining together a pair of light fixture segments at a joint interface therebetween to form a light fixture assembly, comprising a body rotatably mountable on a first of the light fixture segments about a central axis, the body configured to operably engage a drive tool with a drive axis thereof aligned with the central axis to rotate the body between a release position and a coupling position, the body having a designated receiving location to receive a complementary coupling element on a second of the light fixture segments, and configured to provide an arcuate pathway extending from designated receiving location, wherein the designated receiving location and pathway are configured to permit the complementary coupling element to travel along the pathway as the body rotates on the central axis, and thereby to laterally transfer the complementary coupling element radially toward the central axis to draw the first and second light fixture segment toward forming the joint interface when the body reaches the coupling position corresponding to the complementary coupling element reaching a corresponding position along the pathway.

A device is provided for sterile coupling of a percutaneous surgical instrument to a rotary drive tool (5). The device has a flexible envelope (1) confining the drive tool (5), a connector piece (3) coupling to the percutaneous surgical instrument via one end, and to the drive tool (5) via its other end, by passing through the envelope via an opening (12) A tubular ring (2) is positioned on the inner surface of the envelope (1) in the area of the opening (12) and is configured to rigidly connect the envelope (1) to the body of the drive tool (5). The connector piece (3) passes through the ring and turns freely inside the ring when driven by the rotary drive tool (5). The connector piece (3), the ring, and the envelope interact in order to form a leaktight barrier between the inside and the outside of the envelope (1) in the area of the opening (12).

A vehicle component such as an axle spindle or suspension beam (3) is connected to a tubular vehicle axle (1) by fitting a connector sleeve (2) onto the axle and subjecting the assembly to a crimping operation in which plural depressions (206,2018) are formed by indentation in the connector sleeve and the axle wall at the connection region (11,12) to fix the connector sleeve on the tubular axle. In the described proposals a solid lubricant (4) such as molybdenum disulphide is applied at the connection region between the connector sleeve (2) and axle (1), before crimping. The further vehicle component (3) is then connected to the connector sleeve (2) by welding.

A modular plant cage assembly for supporting a plant during all stages of growth includes a plurality of horizontal members that is each curved along a longitudinal axis such that each of the horizontal members defines an arc of a circular segment. A plurality of vertical supports is each removably coupled between the horizontal members. Thus, each of the vertical and horizontal members forms a cage for positioning around a plant growing in the ground. The vertical supports are stackable in a vertical orientation for adjusting a height of the cage to accommodate all growth stages of the plant. A plurality of stakes is each of the stakes is releasably coupled to one of the horizontal members that is positioned at the bottom of the cage. Each of the stakes penetrates ground such that the cage is spaced above the ground.

An agricultural tool unit includes a tool configured to engage the ground and a mounting device. The mounting device supports the tool and presents a device opening configured to receive the frame member. The mounting device includes driving and driven cam elements, with the driven cam element defining at least part of the device opening. The mounting device further includes a cam element shifter operable to selectively impart relative shifting of the cam elements in a first direction. The cam elements present respective cam surfaces that are complementally shaped and slidably engaged with one another to define a cam interface, with the cam interface extending transversely to the first direction such that the driven cam element is moved in a transverse second direction when the cam elements are relatively shifted by the cam element shifter. The driven cam element is configured to adjustably exert a force against the frame member when moving in the second direction.

The present invention provides a system which allows users to mount multiple pieces of equipment to a tower and it has the unique capability to adjust a steel frame to level without additional equipment. In accordance with a first preferred embodiment, the present invention includes a duel locking system that includes a taper adjusting bolt to adjustably position the frame level with the earth. Further, the dual locking system of the present invention preferably further includes the use of retaining bolts to keep the assembly positioned correctly. According to a further aspect of the present invention, once the taper adjusting bolt is in its desired position, the retaining bolts are preferably tightened to lock the frame in place, with the taper adjusting bolt acting as a redundant measure to help maintain the level state.
