Abstract: The present invention relates to a ground compaction apparatus for compacting a subsoil cover layer, with at least one compaction roller, a cover edge processing apparatus comprising an edge processing roller and having a cut material deflector, the cut material deflector being mounted on the cover edge processing apparatus with the aid of a mounting device, the mounting device being configured such that the relative position of the at least one material guide surface of the cut material deflector can be changed automatically with respect to the adjustable roller holding device of the cover edge processing apparatus. The present invention also relates to an asphalt roller having such a ground compaction apparatus and a method for operating such a ground compaction apparatus.

Abstract: A generator stator end winding coil support assembly is presented. The assembly includes a bracket rigidly secured to a core flange plate and a brace clamped between a backup plate and the bracket by studs. The brace connects to an inner support ring. An elastic layer is disposed around the brace. Sleeves are disposed in apertures of the brace and enclose the studs. The sleeves set up a gap at interfaces between the brace and the bracket and between the brace and the backup plate that defines a compression of the elastic layer. The compression enables the brace to be movable relative to the bracket rigidly secured to the core flange plate for flexibly supporting the end winding coils. Flexibility and stiffness of the support is controllable by adjusting clamping force of the studs and selection of the elastic layer based on load conditions during operation.

Abstract: Provided is a method for controlling the cold gas temperature of a cooling gas of a closed generator cooling gas circuit of a generator having at least one cooler through which a cooling fluid flows. The method includes: a) defining cold gas temperature setpoint values in dependence on the stator and rotor current of the generator; b) detecting the current cold gas temperature; c) detecting the current stator and rotor current; d) determining the cold gas temperature setpoint value associated with the stator and rotor current detected in step c); e) regulating the cold gas temperature by changing the volumetric flow of the cooling fluid supplied to the at least one cooler as a function of the difference between the current cold gas temperature detected in step b) and the cold gas temperature setpoint value determined in step d); and f) repeating steps b) to e) at defined time intervals.
