| titleOfInvention | IMPROVEMENTS IN GAS DETECTORS DEVICES. |
| abstract | Improvements in gas detector devices, of the type comprising a detector circuit, an oscillator circuit and alarm element or automatic control system, coordinated through a system of series-transistors activated by circuits, to the circuit of whose transistors, closed to reaching the voltage programmed in the detector transistor, constitutes the activating set of the alarm element through an intermediate power transistor, and in which, the detector circuit is formed by an electronic set transmitter of the output voltage of a transducer, under certain levels, in the concentration of the gas to be detected, at the base of its transistor, while the oscillator transistor constitutes the receiver, in turn, of the oscillation voltage from the oscillator circuit, characterized by presenting the oscillator circuit a capacitor derivation, interspersed in the oscillator set proper, constituted by a set of resistors, before and after the connection of the derivation, and neon lamp, producer of the audible frequency current sent to the oscillator transistor, whose derivation integrates the retarder system of the steady state of the oscillator in its initial slope of the ignition, false alarms, for the stabilization of the functioning of the sensor in the period of connection of the device to the network.
