Description

The present invention is an intermediate auditory and control device for wireless telegraphy, the telephone receiver, which enables the telegraph operator to control his own signals, switches automatically with an open telegraph key to the Internet to a telegraph key and is closed on its own radio frequency generator, powered by itself. antenna antenna

In FIG. 1 shows a diagram of the proposed device; FIG. 2 is a diagram of the variations of the “Eenean Device and the Leagues. 3 - scheme 3j) the last video of the last.

The device consists of a transmitter 11 (Fig. 1) connected to a tone generator 1 and a diode 7, acting on the telephone 14, which is connected via a transformer 12 "receiver 13. The tone generator consists of a lamp 1, an anode coil 2 and a tonal oscillation circuit 3 sound frequency, “in the light of the lamp. The anodic voltage is given by the katungka 2, which at times

radiation of the antenna energy, the high-frequency voltage from the associated katapsha 10 transmitter. The resulting voltage rectifies in a known manner in lamia 1 and causes the tone circuit 3 to oscillate. Tonal oscillations that occur in the rhythm of the transmitted signals are heard in the telephone 14, the switch of which under the action of relay 9 is on contact 4. Relay 9 receives current from a diode 7 having a common ignition circuit with a generator 1 and the anodic circuit of which is connected through a coupling coil 8 by a magnetic flux to cathode 10 of a transmitter. 11. When the telegraph key is not pressed, i.e. : in 1 Interval between signals, relay 9 is without current and switch 5 of telephone 14 is on pin 6 of output transformer 12 of receiver 13. Thus, telephone 14 switches to the rhythm of non-edible signals from receiver to tone generator y and reverse.

In the newly replaced device, odip and the same transformer are alternately used when receiving as an output transformer.

receiver, and in control, as an oscillatory circuit and a communication transformer of a tonal hereratra, the switching is performed by means of non-switch 15 and 16 (Fig. 2) connected to the relay 9 and sliding up to the tacts 17, 18, 19 and 20. Leg 3., transformer 12, together with a capacitor 27, which may be lacking in the presence of a well-known distributed capacity Between the turns of the scrambolt, serves as the oscillating circuit of the tone generator 1. The variable resistance 21 w (using a sliding contact 22 connected to the switch 23in the core 9, and serves during transmissions for shunting telephone 14, in order to reduce the pitch of the control signals.When the telephone 14 is shunted by resistance 21, switch 23 is connected to contact 24. Switch 25 serves to close the oscillating circuit 3 and turn the lamp the tone generator 1 to the rectifier. The safety capacitor 26 separates the receiver 13 from the tone generator.

With a telegram key, i.e. in the absence of current in rectifier 7 and unexcited relay 9, switches 15 and 16 and the last to close the connectors 17 and 19, i.e. the winding 12 of the transformer 12 is connected to the receiver, and the winding 3 together with the body | {) on 14 is shorted.

With a telegraph key, i.e. when u) the passage of the cable through the contour of the transmitting antenna, the excited relay 9 moves the switches 15 and 16, the closing contacts 18 and 20 to the right. Twisting 12 trans-formatter. It is connected in series with the fused jumper 26 of the cathode and the generator 1, and the winding 3 with a 27 l capacitor with the telephone 14 is connected between the cathode and the coil 2 (generator 1.

In another modification of the device,

looking to work with a spark transmitter, in order to eliminate the interference of the transmitter's sound frequency with the own watchmaker tonal generator, defined by the oscillating circuit, achrime switch 28 ((Fig. 3), which will eliminate the spark of the oscillatory Küntush 3 by closing its own gear.
