A method and arrangement for entering a switching program into an electronic timer, in particular a kitchen range timer, wherein the switching program consists of at least one switching cycle within a predetermined time range, preferably within 23 hours and 59 minutes. The switching cycle is timely defined through any two of three entities consisting of switching cycle-start, switching cycle-period and switching cycle-end, wherein the entry is effected serially in the form of sequential input pulses, which have an information relative to the setting direction (forward or backwards) associated therewith, and which is preferably counted in a forward-backward counter arrangement. The entry of a first entity for the definition of the switching cycle is limited to a time interval between the actual time and the end of a pregiven first program range, in which upon the entry of the entity switching cycle-start or switching cycle-end there is set with the first input pulses the present entity to a starting value most closely to the present limit of the first program range but within the first program range, and wherein upon the entry of an input pulse with an associated setting direction which would set the value of the present entity outside of the first program range, causes this input pulse to be rendered ineffective or to selectively erase the present entity.

A power line-operated electronic time-clock including a clock switching circuit, a memory for storage of switching or alarm times, including an input device and a display device, and a power outage-bridging circuit for supplying electrical energy during a power outage to at least the timing components of the clock switching circuit and when required, to the memory storage device. The time-clock includes a monitoring circuit that is interconnected to the memory storage device, and the power outage-bridging circuit for generating a blocking signal in response to the absence of timing data being introduced into the memory device for rendering the power outage-bridging circuit inoperative. Thus, the energy storage device within the power outage circuit will not be drained prior to use or during testing of the clocks. In addition, the monitoring circuit may generate the blocking signal subsequent to a predetermined time interval after a power outage to disconnect the time clocks to prevent drainage of the energy storage device over an extended power shut down.

Power line-operated electronic time-clock

A process and circuit for the setting of an electronic digital display for a desired time period, particularly the cooking time of a microwave oven. The setting is effected through a series of stepping pulses controlling the registers of counter-display units for a time period which is subdivided into predetermined time units.

Process and circuit for the setting of an electronic digital display

A process and an arrangement for the electronic interruption and the cancellations of the interruption of input pulses of a manually rotatable pulse generator in an electronic storage for the purpose of locking the storage condition, including a pulse generator, a first and a second counter, a comparator which is influenced by the two counters, as well as an input key. At the coincidence of the two counter contents, the pulse flow from one impulse-generating element should be so interrupted that the content will be unchanged and also remain constant even when further counting pulses are generated by the input arrangement.
