Patent DE-2706130-A1 (DE)
Title: Multi-potential electronic control for train heating - uses frequency and potential levels as digital signals for non-drift control
Inventor: BRIESKE GERHARD
IPC: B60L1/12
Filed: 1977-02-14
Abstract: The separate heating circuits of the train are arranged following potential and frequency with their addresses converted into proportional digital signals. The pulses are sorted by a simple logic so that the relevant circuits are connected to the supply. The digital signals suffer less from temperature drifting than frequency signals so that a simple control is achieved. A low voltage logic can be used to control the otherwise high voltage supplies. The system can be used for international trains.

Title: Electromagnetically releasable spring pressure brake - has armature disc of two radial parts between electromagnet and friction lining of rotor
Inventor: MAYR FRITZ DIPL ING
IPC: F16D59/02
Filed: 1977-07-04
Abstract: The disc brake rotor (3) is located between two axial pressure faces. Axially movable pressure rings (1, 2), forming the two armature parts, are coaxial and they form the pole plate of an electromagnetic ring (8). Each pressure ring is provided with its own set of compression springs (7, 9). When the electromagnet is energised, the pressure rings are lifted off the friction disc assembly (3). By reducing the voltage in the magnetic coil, the inner pressure ring escapes the magnetic force field and applies a friction force on the brake disc. When the voltage is further reduced, the outer pressure ring follows, thus the total brake force is applied in two stages.

Title: Metal encapsulated HV switch partial discharge measurement - is by LV stimulation of internal voltage converters
Inventor: KOENIG DIETER DR ING
IPC: G01R31/327
Filed: 1978-12-27
Abstract: A method of measuring partial discharges in metal encapsulated high voltage switching equipment involves using the metallic capsule as a measurement screen. It enables full screening of the entire measurement circuit, considerable reduction of the cost of measurement, and yet ensures a high measurement sensitivity. An inductive voltage transducer inside the equipment capsule, either as a part of the original circuit or specially built in, produces the last high voltage. For this purpose its low voltage winding is supplied with an excitation voltage via a low voltage high frequency filter. Several voltage convertes in parallel may be stimulated from a common source. Part of the capsule is fitted with capacitors for discharge measurement and is insulated from the remainder of the capsule.
