An apparatus for electrically charging a rechargeable power source of a pipeline tool while the tool is located within a pipeline comprises a power module including a charging power source, an insertion module including an insertion mechanism having a charging plug for mating with a charging socket of the pipeline tool and a drive assembly operable to extend and retract the charging plug, and a power line electrically connecting the charging power source to the charging plug. The charging power source, power line, and charging plug may be enclosed by a pressure barrier and brought into pressure equalization with the pipeline, wherein the power line does not cross the barrier. The charging power source may include batteries or a generator. If a generator is employed and a pressure barrier must be maintained, a magnetic coupling may be used to transmit kinetic energy across the barrier for input to the generator.

A cylinder (2) for a printing machine, particularly a developing cylinder in an electrographic printing machine, having a rigid, elongated shaft body (10) and a rigid hollow body (11) whose exterior forms the covering and the top and bottom surfaces of the cylinder. In order that, during operation under constant conditions, the cylinder can roll properly against another rigid cylinder of the printing machine, flat sides (12,13) of the hollow body (11) which form the top and bottom surfaces of the cylinder, have centrical bore holes that are larger than the diameter of the shaft body (10) in the area of the flat sides. Located in the space between the shaft body and the flat sides of the hollow body is an elastic material (14,15) which joins the flat sides of the hollow body to the shaft body. Inside the hollow body, in the center between the flat sides of the hollow body one or a plurality of braces (16) are arranged which extend transversely to the figure axis of the shaft body, and which firmly join the hollow cylindrical covering of the hollow body to the shaft body, so that the figure axis of the hollow body and the figure axis of the shaft body coincide in a normal state, and intersect at a small angle under the influence of outer forces.

A power cam drive assembly for generating and delivering two different degrees of force serially to a body, the second force being greater than the first force. A main drive gear is coupled to a driven cam gear which is coupled to an outer cam shell. A cam core is nested within the cam shell for rotation along an eccentric path therewithin. The cam core has an axial extension also coupled to the driven cam gear. A windable clock spring located between the cam core and cam shell has one end secured to the cam core and the other end locked to the cam shell. A cam roller is disposed within the cam core. The clock spring has a greater rotational torque than required to rotate the cam core. The driven cam gear rotates, causing the cam shell to rotate, through the clock spring interconnection, causing rotaton of the cam core with attendant rotation of the cam roller which impacts on a cam stop in its path preventing further rotation of roller and cam core, causing the first force to be transmitted via a lever arranged to transmit the first force to the body. Further rotation of the cam shell causes the cam roller to move in a downward direction, winding the clock spring, resulting in further rotation of the cam core producing the second downward force for transmission to the body via the lever.
