Abstract: A machine tool including a tool spindle, to which a tool can be detachably fixed and by means of which the tool can be rotated, and a workpiece support is provided, the tool spindle and the workpiece support being displaceable relative to one another, characterized in that the tool spindle includes a loading device, which acts on a linearly movable rod of a tool fixed to the tool spindle. The tool spindle includes a motor device coupled to the loading device, which drives linear displacement of the rod. The machine tool includes a set of tools by means of which different machining operations can be conducted on a workpiece, wherein the tools can each be fixed to the tool spindle and the tools each have a rod on which the loading device of the tool spindle acts when a tool is fixed to the tool spindle.

Abstract: A method and a device for the precision turning of a workpiece made of a heat-treatable steel permits a dry hard precision turning of hardened workpiece surfaces without tempering. In order also to allow precision turning and hardening of unhardened workpiece surfaces which are simultaneous in terms of production time, use is made of the local temporary heating of the workpiece caused by machining. The workpiece surface is heated further locally by the action of a laser beam, in the region directly behind the cutter, up to the transformation temperature of the material to be machined via an optical fiber integrated in the tool. The surface is then self-quenched and, as a result, hardened close to the surface. At the same time, the surface temperature at the point of action of the laser beam can be recorded thermographically and, this actual temperature signal can be used to adjust the power of the laser beam so as to maintain the desired temperature.

Abstract: An adjuster device for a deflector fitting of a vehicular seat belt system comprises a first cable (28) connected to a longitudinally adjustable vehicle seat and guided to the circumference of a first pulley (26) and a second cable (18) connected to the deflector fitting and guided to the circumference of a second pulley (24). The pulleys (24, 26) are tensioned one against the other by a spiral spring (36) and coupled to rotate with respect to each other so that overloading of all and any of the components of the adjuster device is avoided.

Abstract: An actuator for a buckle in a vehicle safety belt system is disclosed. A belt tightener engages on the buckle. In operation, the belt tightener moves the buckle towards the vehicle floor to tighten the webbing. An actuating member is arranged at a stationary location so that relative movement occurs between the buckle and the actuating member when the former is moved towards the vehicle bottom. A force transmitting connection permitting such relative movement is provided between the buckle and the actuating member. This connection can be embodied by a flexible cable or by a rack bar and a tooth member cooperating therewith.
