Patent DE-4141690-A1 (DE)
Inventor: HADITSCH WERNER
IPC: H02K9/00
Filed: 1991-12-18
Abstract: In the case of large electrical machines, the electrical connection between the excitation supply lead (7,8) which runs centrally and axially in the rotor and the excitation winding conductors (4) in the winding overhang (3) of the rotor is electrically and mechanically highly stressed. It must therefore be force-cooled. Effective cooling can be achieved if a part of the cooling gas is guided from the cooling-gas chambers through special radial shaft holes (20) to the shaft axis and then radially outwards through or along the excitation supply bolt (13) into the hot-gas space (H) in the rotor winding-overhang space.

Patent DE-4141731-A1 (DE)
Inventor: STRELOW HORST DIPL ING
IPC: G06F11/267
Filed: 1991-12-13
Abstract: The computers (MC1, MC2) of the computer system are associated with common input assemblies (S1.1) for the input signals (E1, E2) to be processed. These input signals are offered in two channels. The input signals corresponding to one another are ANDed with signal protection outside the computers and pass in this form to common input assemblies (S1.1). The input assemblies can be checked for correct operation in familiar manner. The individual computer which is supplied with the ANDed input signals transmits these to the remaining computers (MC2) of the computer system. When the method according to the invention is used, the amount of input assemblies in 2V2 systems which can be checked for their operability is reduced to 50%, and to 66% in the 2V3 system, of the amount compared with a computer system in which this method is not used. <IMAGE>
