    • A tilt-actuated switch features a housing 11 and a contact element 14 movable within the housing between a stable first position and a second position in which the contact element electrically connects two fixed contact elements secured to the housing. The movable contact element responds to tilting of said housing beyond a predetermined critical angle, with respect to the vertical, by flipping from the stable first position through an unstable position (FIG. 2) into a second position (FIG. 3) which is stable. Unlike prior art tilt-actuated switches, this improved switch applies sufficient force against the fixed contacts, even when the tilting is gradual, to assure reliable electrical contact, necessary for applications such as a "dead-man-switch" in a portable radio transceiver.

    • Monitoring of the function of a symmetrical sensor bridge circuit is performed in that the signal from the positive or negative half-bridge is subtracted from half the bridge supply voltage (V.sub.s /2) in a summing member (2) and is subsequently amplified by an amplifier (3) in such a way that it corresponds to the full bridge signal (V.sub.in). The full bridge signal (V.sub.in) is compared with the amplified difference signal in a comparator (5). If the difference signal deviates in an unacceptable manner from the full bridge signal, the comparator switches an alarm signal on the output signal (6) of the sensor, so that this output signal is placed into a range which lies outside of the normal operational range of the sensor.

When the add-on ECU and hydraulic block are installed, and that the housing is mounted on the hydraulic block and solidly joined to it by insertion of the plug-in tubes into the fluid conduits, present in the hydraulic block, in a fluid-tight manner.

    • A method is provided for cooling a low pressure steam turbine operating in a ventilation mode. The low pressure steam turbine has a closable inlet through which steam can be delivered when operating in a power generation mode and which is blocked off when operating in ventilation mode, an outlet which communicates with a condenser for condensing the steam to condensate and a bleed port between the inlet and the outlet. A bleed pipe is connected to the bleed port for diverting steam and/or condensate during operation in the power generation mode. Steam is supplied through a steam transfer pipe to the bleed pipe in order to cool the low pressure steam turbine when operating in the ventilation mode. Condensate may also be supplied to the bleed pipe. The cooling effect in the low pressure steam turbine is largely limited to those components which suffer most when it is operating in the ventilation mode, and the cooling provisions are extracted from resources that are already available.
