摘要： An apparatus for measuring liquid level in a container, particularly the fuel tank of a motor vehicle, has a plurality of detector stages for sensing or detecting a plurality of liquid level ranges, whereby an indicator stage can be arranged to indicate a first, normal range of measurement, and a second, precise resolution can be obtained of at least a portion of the overall measurement range, without requiring an excessively larger indicator stage. This is accomplished by arranging at least two groups of sensing elements one above the other in the tank and connecting them to indicator elements via change-over circuits such that one range of measurement is made via one group of sensing elements and a second, more precise range of measurements is made via a second group of sensing elements.

摘要： A device for the electric monitoring of the level of a liquid contained in a container, comprising at least one temperaturedependent resistance sensor immersed in the liquid the level of which is to be monitored, a constant current source being connectable to the resistance sensor under the control of a program control device controlling a device for detecting and storing the initial voltage drop on the resistance sensor at an initial time and the measurement voltage at a specified time after connection of the constant current source, and a device for evaluating the voltages by subtracting the measurement voltage from the initial voltage and under the circumstances inverting the difference to form a display voltage which corresponds to the level of the liquid. Several of these resistance sensors are arranged at different levels within the container, the sensors being connectable one after the other, controlled by the program control device, to the constant current source and to the device for evaluating the voltage drop on them. A fixed-value storage provides a supply of fixed-value voltages one of which respectively is selectably dependent on the respective resistance sensor active at the time, and an adder is appliable in order to form the display voltage, with the evaluated voltage which is analog to the depth of immersion of the active resistance sensor and with the fixed-value voltage which corresponds to the height of that resistance sensor.

摘要： Electric clock with an oscillator, particularly a quartz oscillator, a frequency divider connected to the quartz oscillator and a control stage connected following the frequency divider, via which control stage a stepping motor, which stepping motor is coupled with the dial train, is able to be applied with pulses of the same or alternating polarity. Each pulse is formed from a number of individual pulses, the pulse duty cycle of the individual pulses reducing toward the end of the first mentioned pulses.

摘要： In a liquid-level transmitter having a swingable support lever (3) which bears a float (7) and a variable electrical resistor (9) actuated thereby, the variable resistor (9) is surrounded by a bell-shaped structural part (1) which is open towards the bottom but otherwise closed. In this way, as in the case of a diving bell, no liquid can enter into the bell-shaped structural part (1) when the level of the liquid rises above the height of the liquid-level transmitter, so that parts of the variable resistor are protected in simple fashion from corrosion due to contact with the liquid to be measured.

摘要： A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver, the gas pedal emitting an electrical signal, the gas pedal being connected with the desired value input of an electrical controller, the output signal of which acts on a positioning actuator, the latter being coupled with the element, particularly the throttle valve, which influences the fuel-air mixture, the instantaneous setting position of the positioning actuator being transmitted as an electric signal to the actual value input of the controller. The actual value input or the desired value input of the controller is driven by a circuit which produces a signal for influencing the position of the throttle valve, which signal is dependent on at least one factor to be monitored.
