Abstract: A multiphase switchgear includes a switch panel, a vertical input housing module and a vertical switch housing module. The switch housing module and the input housing module are spaced apart from one another by a transverse housing module. The input housing module, the transverse housing module and the switch housing module form a first phase block. A plurality of phase blocks are located flush one behind the other in the direction of the transverse housing.

Abstract: A spindle unit for machine tools that includes a working spindle rotationally bearing-mounted in axially spaced spindle bearings in a spindle case, and an electric driving motor. The working spindle includes at its head side a clamping device for a tool and at its rear side a non-rotating ring cylinder for activating said clamping device via a rotating tie rod, and rotational bushing for supplying said tool with cooling and/or lubricating agents through a hydraulic conduit extending longitudinally through said working spindle. At least a segment of the non-rotating ring cylinder may be received in the rear end portion of said working spindle.

Abstract: With technical surfaces, in particular in semiconductor manufacture, it is a regular requirement to determine the reflection coefficient. For this purpose, a model spectrum of an object of a plurality of wavelengths and a defined number of intermediate points is calculated. To increase the calculating speed, the defined number of intermediate points is calculated prior to the execution of the calculation.

Abstract: A torsional-vibration damper T is adapted to be connected to a crankshaft 2 of a motor vehicle. The torsional-vibration damper T includes a primary element 5 of a drive side thereof connected indirectly or directly to the crankshaft 2 substantially free of play in an axial direction “ax.” A secondary element 6 of an output side of the torsional-vibration damper T is substantially coaxially coupled rotatably and spring-elastically to the primary element 5 for transmission of rotational movement.

Abstract: With technical surfaces, in particular in semiconductor manufacture, it is a regular requirement to obtain the reflection coefficient of an inspected object (12). To better match the calculated model spectrum (16) to the obtained measured spectrum (18) with respect to damping when thick layers are measured, the measuring system (10) is measured with respect to its line spread I(?). The measured line spread I(?) is iteratively used for calculating the damping of the model spectrum (16), so that a damped model spectrum (20) is obtained.

Abstract: A device for transmitting linear motion for adjustment of a wing element (4) is provided with one input part (23) and one output part (26) wherein between the input part (23) and the output part (26) an uncoupling mechanism is provided which, above a preset force (release force) makes relative motion between the input part and the output part possible. One or more prestressed springs (42), which can absorb energy during relative motion, upon unloading, restores the input and output parts to an initial position. A translation mechanism converts the relative motion between the input part (23) and the output part (26). The converted motion acts upon the spring (42) whereby a force-path characteristic line of the device, corresponding to the translation mechanism, can be obtained. The translation mechanism consists of a crankshaft (52) with cam discs (50A, 50B) driven by a connecting rod (46) which act upon a piston (48) longitudinally movable within the housing (30) and prestressed by springs (42).
