RECEIVER FOR REMOTE CONTROL OF HUMP YARD LIGHT DIGITAL INDICATOR Russian patent published in 2000 - IPC

Abstract RU 2146205 C1

FIELD: railway transport; centralized control devices for hump yards. SUBSTANCE: device is provided with series connected univibrator and amplifier to output of which input circuit of thyristor optron is connected. Output circuit of thyristor optron is connected to DC source through indicator unit. Complementing input of univibrator is connected with output of first AND gate, and other input is connected with locking output of (N-I) element of code pulse coming from decoding and data recording unit 1 and output of actuating unit is connected with input of indicator unit. EFFECT: elimination of current inrushes through lamps at switching on, provision of gradual switching on lamps. 2 dwg
