A time display which is remotely-synchronizable, especially a time display including timer switching zones or paths for the control of an electrical load or appliance. The time is equipped with a display receiver for the carrier frequency-converted absolute-coded time informations which are receivable through local transmitting intervals for the correction of the time display which is autonomously operated in an evaluating or sample-and-hold.

Remotely-synchronizable time display

An electronic switch apparatus with a capacitor power supply portion which superimposes a current on a consumer circuit encompassing a plurality of power or current consumers which are individually actuatable by a control circuit; for example, consumers including a display module or subassembly, a relay and a control device. At least two of the power or current consumers are connected in series, wherein a switch branch line is connected in parallel with each of these current consumers, wherein the branch line is not conductive when a current flows through the switched-on current consumer which is connected in parallel therewith, which current is also adequate for the other current consumer, and wherein the branch line conducts a current which is adequate for the other current consumer when either no current flows through the power or current consumer connected in parallel therewith or a current flows therethrough which is itself is insufficient for the needs of the other current consumer.

Electronic switch apparatus

A stabilizing circuit for the operating voltage of a microcomputer, in which the input of the circuit is connected to a power supply, and the output of the circuit is connected to the operating voltage-input of the microcomputer. Connected in parallel with the operating voltage-input is a first zener diode, and connected in series with the latter is the collector-emitter section of a first transistor, in which this series circuit is arranged in parallel with the circuit input; wherein there is provided a circuit portion which will deliver a base current to the first transistor for connecting-through of the transistor only then, when subsequent to the switching-in of the power supply, a voltage has built up at the circuit input which, in comparison with the voltage rise of the power supply, leads to a rapid rise in the operating voltage; and in which the emitter-collector current of the first transistor is a constant current which divides itself between the microcomputer and the first zener diode, whereby the first zener diode presently conducts that portion of the constant current which is not employed by the microcomputer in conformance with its current load condition.

Stabilizing circuit for a microcomputer

In a device for measuring maximum energy consumption over a fixed period, a shift register and up-down counter are used to establish a sliding period and the maximum energy over that sliding period stored.
