Abstract: A screwing tool includes a head, which has a fixed jaw and a movable jaw and which is fastened to a handle so as to be pivotable about a pivot axis against a restoring force from a small distance position of the two jaws into a large distance position of the two jaws. In order to be able to touch live parts by means of a screwing tool of this type, the handle has an insulating casing and an actuating element is provided, which can be displaced relative with respect to the handle and which, during its displacement, displaces the head from the small distance position into the large distance position.

Abstract: A method of characterizing a surface topography includes determining scale-dependent parameters. Each of the scale-dependent parameters represents a statistical characterization of a distribution of at least one of a first-order or higher-order derivative of surface height or h determined from one or more measurements of the surface at each of multiple distance scales. For at least one of the one or more measurements, the first-order or higher-order derivative of surface height is determined at the multiple distance scales in real space defined via a scaling factor ? which is greater than or equal to 1 and which is multiplied by the smallest possible distance scale or resolution provided by the at least one of the one or more measurements.

The first connector is connected to the connector for the positive potential of the input, the second connector is connected to the connector for the positive potential of the output, and the control connector is connected to a trigger circuit. A second controllable switch is also included with a first connector connected to the second connector of the first switch, a second connector connected to the control connector of the first switch, and a control connector connected to the connector for the negative potential of the input.

Abstract: A screwdriving tool includes a gear head and a drive arm. The gear head forms a gear housing, in which a free wheel or ratchet gear having an output rotational axis is arranged. A front side of the gear head includes an output coupling, in the shape of a polygon. The drive arm can be pivoted about a pivot axis, which is substantially transverse to the output rotational axis, from a quick-action screwdriver position, in which the drive arm is in the output rotational axis, into a power-action screwdriver position, in which the drive arm extends substantially transversely to the output rotational axis and can be fixed in both pivot positions by detents. The detents can be moved from a detent position into a release position by means of an actuating member associated with the drive arm.

Abstract: The invention relates to a method and to a production line for carrying out the method for producing internal geared workpieces, particularly sliding sleeves. The invention discloses a method, which is advantageous with regard to production engineering, for producing a sliding sleeve and a production line for carrying out the method. With regard to the method, the invention provides that the teeth of the workpiece are made on the finished tooth contour by hob peeling, and the tooth flanks and/or the tooth faces are subsequently machined with a cutting edge tool, and with regard to the production line, the invention provides a shaping device for making teeth having a crude tooth contour, a hob peeling device, which is located downstream from the shaping device and which serves to finish the finished tooth contours of the teeth, and a tooth flank and/or tooth face machining device located downstream from a hob peeling device.

Abstract: A chuck for receiving tools (1) that are operated by rotating around the axis thereof, particularly screwdriver bits, and having an insertion section (3) which is provided with a receiving cavity (2) having a non-circular cross-sectional area (3). The tool can be locked in the cavity (2) by a holding element (4) which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the cavity (2). The holding element (4) can be deactivated by displacing an actuating member in a form of an actuating sleeve (5). The tool (1) rests backwards against the cavity (2). The tool (1) can be displaced from the resting position in the direction of the opening of the cavity (2) by actuating the actuating sleeve (5). In order to facilitate removal of the bit, the chuck also comprises components (15, 16, 17) for releasing the face (1) of the bit, and a magnet (9) which retains the bit in the cavity from the resting position.

Abstract: A computing device with an embedded microprocessor or micro-controller, including a software stack which comprises a content manager, and a runtime environment positioned in the stack above or together with a hardware abstraction layer. The content manager is not specific to any one design of runtime environment or hardware abstraction layer, so that several different designs of runtime environment and/or hardware abstraction layer can each operate with the same content manager. This de-couples the content manager from the runtime environment and/or hardware abstraction layer (e.g. a Java Virtual machine; elements of the operating system). The core advantage is that a single content manager can be used across multiple runtime environments and/or hardware abstraction layers; runtime environments and OSs can therefore be swapped without needing to re-write the content manager.

Abstract: A screwing tool having a torque-introduction part (2) with a cavity (4) in which a profile body (3) is inserted in a rotationally fixed manner, the profile body forming, by its section which projects out of the cavity (4), an operating end (1) for torque-transmitting insertion into a screwing-tool entry opening of a screw head, wherein the torque-introduction part (2) forms a polygonal section for inserting the screwing tool into a screwdriver mount or a bit holder, and the operating tip (1) is rotable, counter to a restoring force, in relation to the cavity-opening edge (4′) as a result of the profile body (3) being secured in the cavity (4) such that it is capable of torsion, having a torsion section (16) formed as a torsion bar. The profile body (3), which is produced from a hardened steel, forms the torsion section (16), which is fitted, by a securing section (18), in the base (4′″) of the cavity, the base being coordinated to polygonal section (17).

Abstract: The invention relates to a hand tool, in particular in the form of a screwdriver or a file, comprising one or more working surfaces with a grooved profile. According to the invention, the grooves are formed by recesses which are created using high-energy irradiation and which have border ribs. The border ribs can be formed by the edges of a fusion which immediately solidifies into a dish-shaped structure.
