Abstract: Tool or adaptor for receiving a tool for securing in a mounting head, including a fork-shaped mounting lug which projects in the direction of displacement and has an enlarged retaining opening starting from a smaller insertion opening.

Abstract: A hydraulic apparatus for pressing or cutting workpieces, the apparatus having a mounting head for use with tools which can be moved against one another. The tools being arranged in the mounting head in a manner laterally offset from one another to allow them to move past each other. As a result of this configuration, there is provided, increased utility value, especially when using cutting tools. The tools are guided in grooves formed next to each other in the first embodiment. In this regard it is possible for a groove to be associated with each tool. In a second embodiment it is provided that the tools are guided in a common groove with additional support on opposite outer surface walls.

Abstract: The invention relates to a piston pump (1) for delivering a fluid at low pressure and at a higher pressure, a higher delivery volume being provided in one pumping cycle at low pressure than at a higher pressure, having a low-pressure delivery piston (4), which is moved inside a pump cylinder (2) and acts upon a pressure chamber (7) under prestress into its delivery end position, a high-pressure delivery piston (11), an inlet valve (9) and an outlet valve (9, 10), a fluid delivery path (5) furthermore being provided between the inlet valve (9) and the outlet valve (10), and the low-pressure delivery piston (4) being able to be moved back counter to its prestress into a delivery starting position, and proposes, to achieve effective delivery at low pressure and at a higher pressure with the simplest possible construction, that the fluid delivery path (5) passes through the low-pressure delivery piston (4), that a valve (6) is provided in the low-pressure delivery piston (4), which valve shuts in the case of move

Abstract: A manual hydraulic apparatus (1) with a traction/pressure installation, for example, a hole punch apparatus, with a hydraulic piston (5) which can be moved with respect to a cylindrical housing (25), and with a holding-up part (2) and a fastening installation (3), for example, for a piercing punch. The fastening installation (3) is rigidly connected to the cylindrical housing (25) and the holding-up part (2) can be moved by the hydraulic piston (5) with respect to the fastening installation (3).

Abstract: The invention relates to a pressing tool (1) for compressing pipe ends. In order to improve such a tool, a bearing (8) and an abutment (13) are configured on the tool (1).

Abstract: In a torque-switched clutch between an input shaft and an output shaft, the clutch transferring into a release position from a positive-locking connection when a limiting torque is reached, at least one positive-locking element is connected to one of the shafts. The positive-locking element interacts with a positive-locking receiver of the other shaft. The positive-locking element is movable against a force out of a coupling position into a release position in a non-destructive manner. The positive-locking element is of latch type design and is mounted on the one shaft so as to be pivotable relative to that shaft for movement between a latch locking position and a latch overrun position.

Abstract: A press tool (1) for pressing cable terminals and connectors or the like onto electrical conductors, having two clamping jaws (2, 3) movable against one another, there being rotatably mounted in each clamping jaw (2, 3), respectively one disc-type press die (27, 29) formed with several different press troughs (33, 34) on the circumference, which press die is lockable in each working position. A second press die (28, 30) is associated with each press die (27, 29), the second press die being arranged to be rotatable independently of the first press die (27, 29).

Abstract: A display device of the type having a plurality of parallel prisms that rotate intermittently and synchronously to present the surfaces of the different panels of each prism for view to provide different composite advertising designs. All the prisms are identical and each is formed with three identical panels that are rectangular and extend longitudinally of the prism. The panels have hinge sections formed integrally along their edges for meshing with hinge sections of adjacent panels in a piano-hinge-like arrangement. A removable hinge pin is disposed in at least one hinge connection so that upon removal of the hinge pin the adjacent panel can be swung open to allow access to the interior of the prism for changing a burned out illuminating device, such as a fluorescent or neon light.
