Abstract: The invention relates to a hydraulic stabilizing system, particularly for a chassis of a vehicle, which has a tank for hydraulic fluid and a pump which are connected by way of corresponding hydraulic lines with front and rear axle actuators, a directional valve being connected in front of the actuators, and the pressure at the front axle actuator being controllable such that it is greater than or equal to the pressure at the rear axle actuator. The invention is characterized in that, between the directional valve for the front axle actuator and the pump, a fail-safe valve is provided and, between the fail-safe valve and the directional valve in the front axle forward flow line, a pressure sensor is provided.

Abstract: A circuit for assuring the supply of voltage to an electronic circuit can be switched to an auxiliary voltage source via a series-connected, self-conducting field-effect transistor when the supply source fails. The circuit, which is realized with very little circuitry, has a voltage divider connected across the load; a tap on the voltage divider is connected to the gate electrode of the transistor. The invention is useful, for example, for protecting data in C-MOS memories of microprocessors.
