SU71604A1 - Signaling device for Bodo telegraph communications - Google Patents

Description

The subject matter of the invention is a signaling device for telegraph communication using apparatus of the BODO type, containing two unpolarized relays with a delay to release and controlled by them sound or light signaling devices.

According to the invention, one of these relays is controlled by a linear telegraph relay and has a deceleration which ensures that it is triggered by a single telegraph current pulse. The second non-polarized relay, which serves to switch the signal circuit, is controlled by the first non-polarized relay and has a release time longer than one turn of the distributor of the BODO apparatus.

The invention is illustrated in the drawing.

The device consists of two telephone relays with a slowdown to release. The circuit of the first telephone relay PI (see drawing) is closed by the contacts of the linear or polarized // relay core, which repeats the operation of the linear relay. The first telephone relay PI attracts its

Measles On receipt of a positive current pulse, i.e., from each correction pulse. Since the PI relay is slowed to release, its measles will, as it were, lengthen the positive (corrective) impulse.

Relay RZ; with a large deceleration of the release, works when the circuit is closed by the contacts of the core relay P-L. When the relay P is triggered, a current passes through the winding of the relay P, which will be the opposite of the current. When only one of the correction pulses, which will be extended by relay P, is received, the relay of the relay will be pulled all the time to the core, since the release time of the relay PI is longer than the time between the correction pulses.

Consequently, when the BODO apparatuses are operating, the relay P will, as it were, repeat the operation of the relay /, and the relay P will all the time be in the tightened position.

During the transition to work on the Morse system, a minus current pulse enters the line, and in this case the relay P does not work, and

relay RZ after a certain time to release their measles and closes the signal chain.

Thus, the call signal at the translation point at the end station transitions to work according to the Morse system, as well as when installing the distributor at the minus contact or when the correction pulses disappear due to poor operation of some regenerator during the correction.

The call is marked with ignition by using a bright lamp 3 or by ringing 4, or both at the same time.

When this line is occupied, the alarm ringing device can be turned off. In this case, the signal neon lamp 5 must be turned on with low current consumption.

When the ringing device is installed on a regenerative broadcast or on a double-disc retransmission, it can be used to set the vibrator to some kind of average speed instead of the speed created by the terminal station devices. Usually, when one of the terminal stations goes over to work according to the Morse system, the retransmission receives a speed of more or less than the speed of the devices of the terminal station, depending on the position of the corrective relay core.

The other side of the retransmission, which continues to work, is at the same time in the worst working conditions due to the deterioration of the correction conditions.

Regenerators at the transition of the terminal station to work on the Morse system can feed their impulses points further to the line only to adjust the balance, and the speed should be created by the terminal station. If the regenerator or transmissions, when the end-station apparatus switches to Morse work, obtains a speed between the speed of the switched on and off correction apparatus, then the operating conditions of the non-switched side of the retransmission will improve and the regenerators will be able to send signals with their own speed to refine further.

This is achieved in devices installed on regenerators or retransmissions so that when the terminal station goes over to work according to the Morse system, the relay P when it is released closes the circuit of the correction element 7 of the vibrator 8 through an additional resistance 6, as a result of which the current will flow through the correction element of the vibrator which is average relative to the current in the correction element with the correction devices turned on and off. The speed of the vibrator, too, thus m. Average.
