SU25201A1 - Generator device for sound lot - Google Patents

Description

A generating device for an audio lot is offered. According to the invention, one of the windings of the transformer with an iron core is included in the anode circuit of the cathode lamp, on the grid circuit which operates the hydrophone current; Another winding of this transformer is connected to the grid circuit of another generator cathode lamp, so that when the hydrophone circuit closes, oscillations of the generator break down, and when sound waves enter the hydrophone, a neon lamp flashing through the transformer into the anode circuit of the lamp mentioned at the beginning .

The drawing shows a diagram of the proposed device.

The constant component of the anode current lamp L sets the negative potential of the grid of the lamp s.52, resulting in a decrease in the anode current of the lamp G. Change in the current in the winding AND the transformer Tr. causes a corresponding change in the current in its winding I, the potential of the grid of the lamp L changes, its anode current also changes.

The lamp grid JL receives an increase in negative potential, which causes a change in the anode current of this lamp. Current ripple in the primary winding of the transformer I Tr. cause voltage changes in the secondary winding II thereof. When the voltage in the secondary winding of the transformer reaches the ignition potential, the neon NL lamp flashes.

The generation will take place in the circuit.

The blink frequency of the NL lamp depends on the amount of negative bias of the BS battery. When the key closes the circuit - the winding I of the transformer Tpi, the hydrophone M, the battery Li, the oscillations fail, because this circuit in the circuit begins to play the role of a suction circuit. If the hydrophone in this case is acted upon by pulses of sound originating from the measured depth, then the resistance of the hydrophone changes, i.e. in the winding circuit I of the transformer Tr, a current varies in magnitude.

It is easy to understand; - that these changes in the current in the transformer and, accordingly, the voltage on the grid of the lamp A, will cause changes in the anode current of this lamp. The latter will cause the anode current of the lamp to change through the transformer Tpg.

A neon lamp flashes in time with the sounds acting on the hydrophone. The advantage of the proposed scheme is that, thanks to the application of the phenomenon of generation, it is possible to make very faint sounds, i.e., sounds resulting from great depth.

If the sound reflected from the bottom, for example, has 1500 kts per second, then by connecting in parallel the secondary winding of the transformer Tpi a capacitor C,

It is possible to adjust the circuit at the same frequency of 1500 CC per second. The tuned circuit will only receive resonant frequency signals.

The subject matter of the invention.

Generating device for sound lot, characterized in that the anode circuit of the cathode lamp Jf, on the grid circuit of which the current of the hydrophone acts, includes the winding II of the iron core transformer Tpj, the winding I of which transformer is included in the grid of the cathode lamp JIi in order to when the hydrophone circuit was closed, the oscillations of the generator disrupted, and when sound waves entered the hydrophone, a neon NL lamp would flash, connected through a transformer to the anode circuit of the lamp L.
