发明名称 MINER'S APPLIANCE FOR INDIVIDUAL GAS PROTECTION AND MINE ILLUMINATION
摘要 The miner's appliance for individual gas protection and illumination in which the first output of the accumulator battery is positive, and the second one is negative, the current-restricting resistor is the transistor, collector of this one is connected to the anode of the diode, and the emitter - to the cathode; at that the base of the transistor is through control circuit with connected in sequence diode and resistor is connected to the positive output of the accumulator battery; besides that the gas signaling unit includes voltage stabilizer, this is with the output connected to the inputs of the methane sensor and re-adjustable divider of support voltage, the outputs of those ones are connected to the inputs of the comparator, the output of this one is through multi-vibrator connected to the input of the emitter repeater with relay, normally closed contacts of this one are connected to the circuit of the lamp headlight power circuit.
