Abstract

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.
