Abstract
923,743. Protective arrangements. COMPAGNIE DE CONSTRUCTION DE GROS MATERIEL ELECTRO-MECANIQUE. March 10, 1961 [March 11, 1960; March 28, 1960], No. 8929/61. Class 38 (5). [Also in Group XXXVIII] In a fault-indicating system in which it is desired to indicate which fault occurred first, which occurred second and so on, each fault indicating line has a plurality of storage and indicating devices associated with it, and the arrangement is such that the first fault is registered and indicated by the first storage device of the storage devices associated with the line on which the first fault indication occurred, the second fault is registered on the second storage device of those associated with the line on which the second fault indication occurred and so on. The embodiment shown in Fig. 1 merely indicates which of three faultindicating lines 1, 2, 3 receives a pulse first, and those which receive pulses subsequent to the first. In the rest condition, as shown, the upper contacts of relays RC 1 , RC 2 and RC 3 are closed. The first pulse received, indicating the first fault, then passes to the associated first storage device M 11 , M 21 or M 31 . This storage device registers and indicates the pulse, on a lamp, and also via diode or gates energizes the relays RC associated with the lines which have not yet carried a fault indication so that all fault indications subsequent to the first are registered on the second storage devices M 12 , M 22 , M 32 .
