Abstract: A motor-operated shears which includes two blades that can move towards each other to perform a shearing movement is provided. In order to advantageously improve functional safety, towards the end of the movement, the blades are acted upon in a direction running transversely to the movement so as to keep the blades at a distance from one another in said direction.

Abstract: A working tool has a working head and a body device. In an embodiment, an electric motor having a drive shaft with a longitudinal axis, and a transmission are connected to each other and are in the body device. In an embodiment, the working head is a hydraulic cylinder with a hydraulic piston that can be moved between extended and retracted positions in a direction of travel. A hydraulic medium pump and a drive for the hydraulic medium are provided in the body device. In an embodiment, the transmission is connected to the electric motor so as to be movable in the direction of the longitudinal axis in such a way that it is limited by a limit stop. In an embodiment, the hydraulic cylinder is attached to the body device so as to be movable in the direction of travel that it is limited by a limit stop.

Abstract: The invention relates to a hydraulically actuated piston (9) guided in a cylinder (8), and to a hydraulic working tool (1) having a working head (2), wherein the piston (9) has an impact surface (15) which borders an impact space (16) on the piston side provided between the piston (9) and the cylinder (8), and wherein hydraulic fluid (17) can act on the impact surface (15) by increasing the impact space (16) in order to move the piston (9) in an impact direction (r), and the piston (9) forms a limiting device (25) for a through-flow of the hydraulic fluid (17).

Abstract: A device is used to sever an electrical power cable for the transmission of high voltage. The cable has an insulation sheath, a screening layer and a conductive layer. The device includes a first frame having a first cutting blade mounted thereon, a second frame, and a measuring device mounted on the second frame. The first cutting blade is movable relative to the measuring device. The measuring device is capable of measuring an electrical load on the electrical power cable and capable of terminating the severing of the electrical power cable. A method of using the device is also provided.

Abstract: A body supporting structure for a vehicle body has a passenger-compartment section, a front-structure section and a rear-structure section. In order to form the body supporting structure, at least one supporting-structure body is configured as a three-dimensional flat structure which extends in all vehicle directions (x, y, z direction) and includes flat elements, the flat elements which extend in different vehicle directions (x, y, z direction) are connected with the formation of soft transitions, the flat elements are configured with cross-sectional areas which are structured depending on the applied loads, and flat elements with low applied loads or non-loadbearing regions are configured with apertures.

Abstract: A cooling arrangement for cooling laser gas for a gas laser includes a first cooling circuit having a first cooling assembly and a first heat exchanger for cooling laser gas which flows from a fan to a resonator of the gas laser, and a second cooling circuit which is independent of the first and which has a second cooling assembly and a second heat exchanger for cooling laser gas which flows from the resonator to the fan. The second cooling circuit has at least one additional heat exchanger for additionally cooling the laser gas which flows from the fan to the resonator.
