A hydraulic pressure vessel long seam welding jig device having a triangular frame, a pair of hydraulically actuated clamp mechanisms each having a clamp activating hydraulic cylinder operatively associated therewith, whereby each of the clamp mechanisms are positioned on opposite ends of the carriage beam and arranged to hold a workpiece during a long seam welding operation.

A method of installing a plurality of nut and bolt fasteners upon a structure is disclosed. The method includes placing a jig around the nut of a first fastener and the nut of a second fastener, securing the jig to the first fastener, and then using a power tool to tighten the nut of the second fastener to a target torque. The step of tightening the nut comprises engaging a socket portion of the power tool with the nut, securing the power tool to the jig such that a handle portion of the power tool is prevented from rotating about an axis of rotation of a socket portion of the power tool when the nut is being rotated by the socket portion. A jig, jig fasteners for securing a jig to a fastener, and a fastening head for a power tool are disclosed.

The invention relates to a drive transmission for converting a drive movement into an output movement, in particular in a swing clamp (1) for clamping components. The drive transmission according to the invention first comprises a movable drive element (9), in particular in the form of a piston, which carries out the drive movement during operation. Additionally, the drive transmission according to the invention has a movable output element (4), in particular in the form of a rod, which carries out the output movement during operation, and a cam gear, which converts the drive movement of the drive element (9) into the output movement of the output element (4) according to a specified transmission curve, wherein of the drive movement and the output movement, one movement is or contains an axial movement along a specified movement axis while the other movement is or at least contains a rotational movement about the movement axis. According to the invention, the cam gear has two contact surfaces (F1, F2) which slide against each other in a planar manner and thereby convert the drive movement.

A positioning guide device for positioning a blank in a forming die. The positioning guide device includes a positioning guide having a sloped positioning face designed to allow a peripheral edge of the blank to be positioned in a transverse direction by contact with the positioning face. The positioning guide device further comprises a housing module, the positioning guide being mounted in the housing module so as to be linearly displaceable in the transverse direction. The housing module having a spring system for preloading the positioning guide in the transverse direction.

Modular carriage for varying spacing between ends of polymer pipe during fusion. The modular carriage includes a fixed jaw; an inner movable jaw; an outer moveable jaw and a plurality of guide rods. The fixed jaw being adapted for tool free engagement with the terminal ends of the plurality of guide rods. A carriage cylinder is associated with at least two of the guide rods and mounted for reciprocal travel along the length of its associated guide rod. The movable jaws being adapted for tool free engagement with at least two carriage cylinders for reciprocal travel therewith. A combined hydraulic cylinder/guide rod includes a guide rod with an integral guide rod piston, a cylindrical tube, and a guide rod gland on each end of the cylinder tube.

Clamping or gripping device with a main body, with guide portions provided on the main body, with jaws which are movable along the guide portions in a direction of movement, which can be moved between an inner stroke position and an outer end-of-stroke position, the jaws each having a row-of-teeth portion with, in each case, a length extending in the direction of movement, and with multiple pinions, the axes of rotation of which lie in a plane lying parallel to the respective row-of-teeth portions, the pinions interacting with the respective row-of-teeth portion to drive the jaws.

Systems and methods for operating deep brain stimulation are disclosed. In certain embodiments, the systems and methods encompass an adapter a body portion, a shank portion; and a cam system. The cam system is comprised of a camshaft and an eyebolt that secures a latch. The body portion of the adapter is coupled to a hand knob of a microdriver and the shank portion is coupled to a drill. When the drill is activated, the adapter transmits rotational energy from the drill to the hand knob of the microdriver, which automates the raising and lowering of its needle.

A clamping apparatus includes: a support member (19) inserted in a leading-end-side portion of the housing (1) so as to be movable in its axial direction; a resistance giving mechanism (34) configured to give resistance to axial movement of the support member (19); and an engagement maintaining mechanism (26) configured to maintain engagement between a wedge surface (24) of a clamp rod (7) and a locking member (23). When the clamp rod (7) is driven toward a leading end side for unclamping action, the clamp rod (7) moves the locking member (23) toward the leading end side via the support member (19) after the locking member (23) moves radially inward.
