Abstract

858,206. Electric selective signalling systems. BROWN, BOVERI & CIE. A.G. Oct. 9, 1958 [Oct. 9, 1957], No. 32304/58. Class 40 (1). In a mine signalling system, Fig. 1, signalling from the cage 15 to the ground level winding control station is effected by varying the electrical transmission characteristics of the cable 1 carrying the cage. In a first embodiment, Fig. 1, by means of a switch in the cage, either a capacitor, or an inductance or both a capacitance and an inductance can be inserted in series in the cable loop. At the control unit the particular selection made in the cage is detected by inducing a current in the cable loop by a transformer 4 and coupling the current so introduced via a transformer 5 to a phase responsive device 7 which causes the contact of a polarised relay 9 to assume one of three positions corresponding to the position of the switch in the cage. The device 7 also receives the supply current via networks 13 and 14 to act as a reference phase. In a second embodiment at the cage, one of three resonant circuits resonant at different frequencies is inserted in series in the cable loop, and the particular circuit chosen is detected at the control unit by inducing the cable loop all three frequencies and detecting that one which is not substantially blocked. In a modification the circuits inserted in the cable loop at the cage can be done so inductively.
