SU111254A1 - Device for regenerating telegraph signals at the start-stop device - Google Patents

Description

The invention relates to the field of a device for regenerating telegraph signals; gov.

The known devices of the same designation use the constant speed of rotation of the distribution sleeve or the axes of the start-up apparatus and sliding contacts in the form of carbon rods or brushes.

The proposed device differs from the known ones in that, simultaneously with the regeneration of signals at the output of the apparatus, it converts unipolar telegraph packages into bipolar, by including the contacts of the regenerator into an additional winding circuit of the control relay.

FIG. 1 shows the structure of the device; in fig. 2 is a schematic diagram of the device when the start / stop telegraph apparatus is connected to the input of the voice telegraph apparatus; in fig. 3 is a schematic diagram of the device when the start / stop telegraph is wired to another start tone telegraph.

On the clutch of the transmitter of the start-stop device (not shown in the drawing), an additional disk I (Fig. 1) is installed with seven cams located equidistantly around the circumference.

The spring contact of the regenerator 2 (Fig. 1 and Fig. 2) is pressed onto the disk /.

The spring contact of the regenerator 2 works on the opening when the spring slides off the steep cam disc / and on the circuit when it returns to its original position along a gentle slope.

The contacts of the start-stop transmitter 3 and the contact of the regenerator 2 (Fig. 2) are included in the winding circuit of an additional polarized relay (type RP-4) 4.

№ 111254

At the moment of the start-stop key, the distributor clutch together with the additional disc / begins to rotate. The contacts of the transmitter of the apparatus 3 are opened, but the contact of the regenerator 2 remains closed until the transmission of the middle part of the stop package. When the contact of the regenerator is closed, regardless of the ratio of the currents in the main windings of the lull relay, the relay of relay 5 remains at its contact, since all the time the additional high-resistance /// and IV relays are connected, the magnetizing force of which is greater than that of the main windings. Additional windings are included along the circuit: minus 60 V, contact and relay of relay 5, resistance 6, additional windings /// and IV pe; ie, contact of the regenerator 2 and earth.

When transmitting the middle part of the stonewatch, the spring of the contact of the regenerator 2 falls into the complementary disk / and the additional windings of the /// and IV relay 4 are opened for a time equal to 10-15% of the time of the elementary parcel.

At the moment of opening the contact of the regenerator 2, only the main windings / and // relay 4 are turned on, and its operation depends on whether the contacts of the non stop of the stop-stop device 3 are closed or open.

When the contacts of the nonresponsive start-stop device 3 are closed, the current in the winding / as compared to the current in the winding prevails //. When the contacts of the transmitter of the apparatus are open, the current in the winding / is absent and the winding // remains on.

In the middle part of the starting parcel, when the contact of the regenerator 2 is opened, the switch of relay 5 does not drop from the negative to the positive contact. When the contact of the regenerator is closed, the bark of the relay 5 is held in its pulled position until the next break. All subsequent disconnecting of the contact of the regenerator occurs exactly in the middle parts of the irreducible parcels.

Depending on the frequency of my combination at the time of the opening of the contact of the regenerator, the switch of the relay 5 is either thrown to another contact, or returns to the previous contact.

When the start-stop aiuiapaTa does not operate on the input of the voice telegraph equipment, but with a different start-stop device, the excivia of the regenerator must be changed as shown in FIG. 3. The principle of operation of this scheme is similar to the above) with the sleigh (Fig. 2).

This scheme differs in that the electromagnet of the receiver is connected in series into the contact circuit of d.che 4, and the bipolar potential at points L and B, when operating its apparatus, is obtained by redistributing the potential sections of both batteries (Fig. 3).

If both atetottopic apparatus is standing on a foot, then at the point L (Fig. 3), a positive step and a relay 4 of its station holds the measles of relay 5 in the position of the operating cohgkt. At point B, at this.m, the negative potential and the relay 4 protpvono; the 1-station also holds the switch of the relay 5 at the working contact.

When transmitting etancipus with point B, the potential of point B remains undetermined, and the potential of point L will be positive. If the relay core 5 is located at the working contact and negative when the relay 5 core is located at the rest contact. This bipolar signal is used to block the relay from its station to the closure contact of the regenerator 2.
