摘要： The invention relates to a portable, battery-powered hydraulic unit for hydraulic rescue tools, in particular for spreading or cutting tools, as well as a rescue tool equipped therewith. The hydraulic unit comprises at least one hydraulic pump, a hydraulic tank, a compensation device for hydraulic fluid, a manually operated hydraulic control valve, an electromechanical interface for on-demand coupling and decoupling of at least one battery pack, a mechanical-hydraulic interface for connecting a hydraulic tool, and an electric motor operable by the electrical energy of the battery pack for driving the hydraulic pump. The electric motor is formed by a disc motor whose axial length extending in parallel to the longitudinal axis of its output shaft is shorter than its outer diameter.

摘要： A hydraulic unit for supplying pressure to a hydraulic steering system is provided having at least two hydraulic cylinders and at least one hydraulic pump (9, 10, 32, 33). It is essential that the hydraulic cylinders are of interacting configuration, by an annular space (6a, 6a, 28a, 28b) of the first hydraulic cylinder being connected via at least one hydraulic line to an annular space (6a, 6a, 28a, 28b) of the second hydraulic cylinder, and a piston space (5a, 5b, 29a, 29b) of the first hydraulic cylinder being connected via at least one hydraulic line to a piston space (5a, 5b, 29a, 29b) of the second hydraulic cylinder, and a hydraulic pump (9, 10, 32, 33) being arranged at least in a hydraulic line (7, 8, 30, 31) between the two annular spaces (6a, 6a, 28a, 28b) or in a hydraulic line (7, 8, 30, 31) between the two piston spaces (5a, 5b, 29a, 29b). Furthermore, the invention relates to methods for operating a hydraulic unit for supplying pressure to a hydraulic steering system, and to a steering system.

摘要： A method for producing round stock (10) which is provided with at least one inscription and/or marking (16), at least the surface (12) of the round stock (10) consisting of a metallic material, in particular of chromium or steel, for example of hardened steel, chromium-plated steel or stainless steel. In order to improve this method such that disadvantages and shortcomings are avoided, the method includes the following steps: placing on the surface (12) at least one cover (20) which is adapted to the shape of the surface (12) and in particular has the inscription and/or marking (16), such that the region to be provided with the inscription and/or marking (16) is not covered by the cover (20),—exposing the round stock (10) to a first electrolyte (30) together with the cover (20), material being removed from the surface (12) by said electrolyte in the region to be provided with the inscription and/or the marking (16) while producing depressions (14), and—exposing the round stock (10) together with the cover (20) and the depressions (14) not covered by the cover (20) to a second electrolyte (32) by which the depressions (14) are filled to produce the inscription and/or marking (16) which differs from the surface (12) optically, in particular with respect to color. The present invention also relates to round stock (10) which is manufactured from a metallic material, with the round stock being provided with a correspondingly produced inscription and/or marking (16).

摘要： A rescue system includes a mobile rescue device, in particular a spreading device, a cutting device, or a combined device having a spreading and a cutting function, including a base body with a handle, a working device arranged at the base body, a controller for controlling the work sequence of the working device, and an input device arranged at the base body for inputting control commands into the controller. Furthermore, an external additional input device is formed, which is structurally independent of the mobile rescue device and coupled or couplable with the controller of the mobile rescue device by a data transmission device.

摘要： A sensor (S) is provided for determining the stroke of the piston rod (6) of a fluid cylinder, particularly a hydraulic or pneumatic cylinder. The sensor includes a lighting unit for illuminating a code applied on the surface of the piston rod and differing from said surface by color, a first camera unit with a first lens system for recording a first image of the illuminated code in a first scanning window, an evaluation unit for evaluating output signals of the first camera unit, and an interface for issuing the evaluated output signals as information regarding the position of the piston rod. Additionally, a second redundant camera unit is provided with a second lens system, which serves for recording a second image of the illuminated code in a second scanning window. According to the invention the second camera unit is arranged such that the second scanning window is spaced apart in the direction of the extension of the piston rod by a predetermined value from the first scanning window of the first camera unit. The output signals of the second camera unit are evaluated in an evaluation unit as information about the respective position by forming a difference, with in case of said difference being consistent with a predetermined value the output signal being considered information about the stroke of the piston rod, and in case of inconsistency of the difference with the predetermined value an error message being issued.
