A provision of logical circuit of type of coincidence or y. (Machine-translation by Google Translate, not legally binding)

摘要

A logic circuit arrangement of the coincidence type, or safety Y, that is, it supplies in output signal information corresponding to the most restrictive safety position in case of accidental disarrangement of one of its components, which has, in combination , at least one DC power source, an identical operating electronic transistor or organ connected to said source, at least two transistor control circuits, and a transistor output circuit whose only two information transmitted correspond to the presence or absence of oscillations, the elements of the logic circuit being chosen in such a way that the only two information capable of being supplied by the transistor represent a state of oscillation when the input signals sent on the control circuits have simultaneously non-zero values and a resting state when one at least of these values It is null.
