Abstract: In a demodulator for traffic broadcast programme (VRF) and radio data system (RDS) demodulation, it should always be possible to pick up the RDS signal at a particular output terminal independently of whether the VRF carrier is present or not. The demodulator is therefore constructed in accordance with the principle of a Costas loop circuit, the control variable of the Costas loop for the oscillator being inverted as soon as a VRF carrier is present. If the VRF carrier itself is to be evaluated for the purpose of demodulation, the disadvantage of ambiguity exists since the Costas circuit only unambiguously locks on with modulo  pi . To eliminate this problem, the control variables are switched over in dependence on whether a VRF carrier is present or not so that, on the one hand, a Costas action and, on the other hand, a usual PLL action is given in which the stable lock-on phase is unambiguously modulo 2 pi . <IMAGE>

Abstract: A variable speed hydro-power plant includes a pump turbine (2) having a S-shaped characteristics at the turbine operation. A current time turbine operating point is grasped on a turbine characteristics diagram of the pump turbine (2). A limit operation characteristics curve (nr) of the pump turbine (2) is formed in advance so as to not reach the S-shaped characteristics turbine operation region. A reach of the limit operation characteristics curve (nr) is detected, a rotating speed (N) of the pump turbine (2) is lowered. An inrush of the pump turbine (2) into the S-shaped characteristics turbine operation region is eliminated, so the continuation of a stable and reliable turbine operation can be guaranteed.

Abstract: Faults in the speed control electronics must not cause unacceptable acceleration of the washing drum at the incorrect program time. This must be prevented with the aid of protection devices. Protection devices of a known type make use of a circuit with a relay and always interrupt the motor circuit on reaching a previously set maximum speed value. The new protection device is triggered only when a specific drum speed (or speeds) is (are) exceeded and no nominal spin speed has been preselected by the user at the same time. A centrifugal force switch, with a switch-on contact 6 that triggers a relay 4, is coupled to the drive motor 1. With the aid of its switch-off contact 3, the relay 4 interrupts the motor circuit. The protection device is effective only when a switching element 7, triggered by the speed control electronics 5, is closed. The method for protection against unacceptable drive motor acceleration is especially suitable for domestic washing machines. <IMAGE>

Abstract: In a small-section rolling mill with a water cooling stretch before the finishing train for thermomechanical finish rolling, in each case one stand group of the intermediate train or of the intermediate trains, which is set for the rolling of a larger finishing cross-section than the smallest possible finishing cross-section, is transferred to a stand location of the finishing train, immediately upstream of which is arranged a water cooling stretch. The finishing train for the smallest possible finishing cross-section no longer needs to be converted for larger finishing cross-sections, but is simply replaced by a stand group from one or more intermediate trains. For transferring stand groups, crane work can be eliminated if quick change devices are used which are all connected to one another by a pair of rails which extends parallel to the rolling line and as far as the stand location or locations of the finishing train. Thermomechanical finish rolling of the larger finishing cross-sections can be achieved without having to convert the finishing train for all desired finishing cross-sections.
