Abstract: The present invention relates to a device for the regulated temperature control of a gas discharge lamp, and a gas discharge lamp. The device according to the invention includes a transformer core of a transformer, the transformer core being designed for accommodating at least one discharge current-conducting connecting line of the gas discharge lamp as a primary winding. The transformer forms an energy source for heating a functional area of the gas discharge lamp that determines a function of the gas discharge lamp, and that is formed by an amalgam reservoir. The device also includes a secondary winding on the transformer core, and a means for temperature control that is used to regulate the energy that heats the amalgam reservoir. The means for temperature control is electrically connected to the secondary winding.

Abstract: The invention relates to an oscillatory drive having an output shaft that can be driven to perform a rotationally oscillating movement about its longitudinal axis and that comprises a free end, a holding fixture at the free end of the output shaft comprising a contact surface for attachment of a tool, a mounting section on the holding fixture, raised relative to the contact surface, that projects to the outside in the direction of the longitudinal axis and that is designed for form-locking connection with a mounting opening of a tool placed in contact with the contact surface, and having a securement for fixing the tool with its mounting opening on the holding fixture, the securement permitting the tool to yield in axial direction under the action of a torque, against a pre-stress, and the mounting section permitting the tool to rotate by a certain angle of rotation when the tool gives way axially.

Abstract: A hand-held power tool (10) is specified, comprising a work spindle (12) for driving a tool (68), said tool (68) being fastenable between a fastening element (38) and a holding portion (36) on a tool end of the work spindle (12), and a displacement device (24) for sliding the fastening element (38) between a released position in which the fastening element (38) can be detached from the work spindle (12) and a clamped position in which the fastening element (38) is clamped against the holding portion (36) by a spring element (48). The fastening element (38) includes a clamping shaft (42) that is insertable into the work spindle (12) and held in the clamped position by a lock assembly (54) inside the work spindle (12), and which can be removed when in the released position (FIG. 2).

Abstract: A displacement control device (1) is adapted to move a member (23) relative to a body (7). The displacement control device includes a drive means (2, 3) and an emergency actuator(8) arranged mechanically in series with the member. The actuator includes a housing (16) and a spring (14) arranged to act between the housing and the member. The improvement comprises: the actuator including a toggle linkage (9) acting between the housing and the spring, the toggle linkage having two pivotally-connected links (10, 11) that are adapted to be selectively moved between a collapsed position at which the links are arranged at an acute included angle, and an extended position at which the links are arranged at an obtuse included angle slightly less than 180°. The toggle linkage is arranged such that the spring will be more greatly compressed when the links are in the extended position than when the links are in the collapsed position.

Abstract: The present invention refers to a transmission unit comprising a transmission input, a transmission output, at least one first main transmission stage and a second main transmission stage connected in series therewith, and a housing encompassing said first and second main transmission stages in common, at least said first main transmission stage being defined by a gear/shaft carrier provided with at least one shaft and at least two gears, and the thus defined first main transmission stage being replaceably inserted in a reception bore of the housing as a modular unit.

Abstract: The teeth of the sun pinion, planet wheels and hollow wheel have a profile correction changing continuously along the gear width and varying in opposite directions between the meshing gears. The sun pinion, hollow wheel and planet carrier are so mounted as to be fixed in the axial direction, whereas the planet wheels, allowed to slide individually in the axial direction on their stub shafts rigid with the planet carrier, are responsive to the axial force exerted by cup springs and mounted for swivel movement within predetermined limits on pendulum bearings. Furthermore, all the wheels, pinion and hollow wheel have crowned teeth.
