Abstract: The invention related to a handheld power tool having a linear actuator and a removable member, e.g. a blade, wherein the movable member is directly connected to the actuator via a connecting rod, which pushes the movable member during a work stroke and pulls the movable member to a starting position during a return stroke. One end of the connected rod is connected, via a concentric dual ball-and-socket joint, to the actuator as well as to a guide ring that slides inside the cylindrical body of the tool. Lateral and bending forces are taken up and transmitted to the body of the tool by the guide ring without affecting the actuator. The ring defines a sealed space that houses the actuator. An axial cavity of the connecting rod partially houses the actuator in the retracted position, thus reducing the length of the tool.

Abstract: A drive shaft assembly for a downhole motor includes a drive shaft formed with convexly spherical bearing surfaces on each end, and end housings with concavely spherical bearing surfaces for mating contact with the spherical bearing surfaces of the drive shaft, thereby facilitating omni-directional articulation between the drive shaft and the end housings while transferring axial thrust loads between the drive shaft and end housings across the interface of the mating spherical bearing surfaces. Torque is transferred between the drive shaft and end housings through two or alternatively four swivelling drive keys mounted to each end of the drive shaft and engageable with complementary drive key slots in the end housings. Full and constant torque-transferring contact is thus provided between the swivelling drive keys and the end housings irrespective of any angular offset between the drive shaft and the end housings, resulting from omni-directional articulation of the drive shaft relative to the end housing.

Abstract: A serpentine tube inspection positioning spine formed from a plurality of identical links mated together. Each link has first and second bifurcated ends with the first end sized to fit within the second end of an adjacent link. Links are mated together by a pivot pin or axle which is accepted in a bore through the bifurcated ends. The second bifurcated end is provided with a substantially oval-shaped bore to allow sliding of the adjacent links relative to each other. Flat alignment faces on each end, with the first end having rounded corners, prevent buckling due to compressive forces during insertion while still allowing pivoting of the links for traveling through tubing bends.

Abstract: The joint comprises two opposed forks which are angularly offset from each other at 60.degree. and are axially extended by nose portions which are internally spherical. These nose portions swivel on a ring through which extends with a large clearance a shaft section which carries at each end a tripod element associated with one of the forks. The ring is maintained roughly in the bisecting plane of the joint by contact or quasi-contact with the rollers of the two tripod elements. In this way it is possible to produce steering road wheel homokinetic joints which are capable of operating at angles of 50.degree. and more with no reduction in their transmitting capacity.
