摘要： Intermittent operation of a pump feeding fuel to the battery is controlled by circuits which produce pump operation cycles at intervals determined by energy used in the load circuit as well as additional cycles if the voltage falls below a fixed limit. Compensation for the drop in concentration of the fuel as the result of recirculation of partly spent fuel is provided by lengthening the pump operation cycles or making them more frequent with respect to power energy consumption in the load, or both.

摘要： An arrangement for generating an electrical switching process when a predetermined quantity of electrical charge has passed through an electrical conductor. A resistor used as a measuring element is connected in series with the electrical conductor, and the voltage appearing across the resistor is applied to an integrator. The switching device in the form of a trigger circuit provides a trigger signal when the output voltage from the integrator has attained a predetermined threshold magnitude. This threshold magnitude is selectable in correspondence to a predetermined and selected quantity of electrical charge to be passed through the electrical conductor. The trigger signal is also used to clear the integrator circuit.
