The present invention discloses a device and a method for mains-side control of an intermediate circuit voltage in order to reduce or eliminate impermissible mains effects of harmonics of the mains voltage on the intermediate circuit. For this purpose, dur...

The basis of an automatic control system for determining the need to counteract wheel slip by discharging sand is a fuzzy control system which determines four levels of weather conditions and relates them to the degree of slip recorded. Two ambient tempera...

The procedure for the regulating of a pneumatic spring entails using sensors (10,11) to record measured variables which are the heights and pressures of the pneumatic springs (1-4). The measured signals are error checked, and the faulty measured values are...

The rail vehicle has a wagon box (1) with window apertures in the side walls (7) and separating window part (6). Each window aperture has a holding web pointing radially inwards and set back. The outsides of the window parts are set back to the same plane ...

Convex curvature of the underside (14) causes the slipstream in each direction (S,K) of travel, to flow more rapidly under the lower side than over the upper side.

The system has a device (1) for manual entry of a first vehicle speed demand, an automatic controller (2) for automatically determining a second vehicle speed demand according to a boundary condition stored in a memory device and an inference system (3) th...

The method involves forming a differential speed value (deltaV) from the actual speed value (Vist) and a predefinable desired speed value (Vsoll). A limited desired acceleration value (asoll) is formed from the differential speed value and a first mass-dep...

The overload protection device has an instantaneous current limiter (1) with a controller (5) that responds to a current threshold being exceeded by blocking a branch pair (4) and responds to the current falling below the threshold by re-enabling the branc...
