Description

The present invention relates to the already known multiple duplex telegraph retransmission hub, which provides intermediate communications and transmits in non-short directions through terminal multiple duplex telegraph devices operating in these directions and having common-mode rotations using local correction.

According to the invention, in such a refocusing hub, in order to quickly change the direction of translation, two switches are used for correctional and translational x 1 local circuits of the terminal equipment included in the respective directions.

The drawing shows a diagram of the proposed duplex retransmission of the hub.

Compared to ordinary two-HEADS (The Bodo-duplex M single-disk set contains the following changes.

On the front disc PD in the fifth ring V against the contacts 22, 23,24 of the second ring // there are three corresponding contacts, of which

the middle one is connected to the main part of the fifth ring V and the two extreme ones are connected to the windings of the correction relays MK installed on each -IZ of the single-headed sets included in the hub. To the contacts of the correction relay MK, a local PBDB battery and ground are connected. Contact 22 of the second ring // is connected with the plus of the local MB, and to contact 24 is the minus of this battery. In parallel with the windings of the YAR printing relay, the windings of the translational (common) TP relay are included. The contacts of this relay are connected plus and minus the local battery L4B, and its measles are connected to the windings of the transmitting PDR relays installed on each of the single-headed kits connected to the hub. The rear disk of the concentrator’s ZD accepts a local correction from one of the kits included in (concentrator. For this, on the fourth ring IV against the contacts of the first ring / there is a lamella attached to the root of the correction relay L1 /. To pin 23 of the first ring I of the back disk hub attached correction electromagnet

KZ The switchboard of the keyboard of the first sector is through a switch I am connected to the core of One of the translational TPi relays that have shields in sets, | B1KlyuchenyHX in the hub.

The change in the layout of the single-headed kits included in the hub is summarized as follows. On a pointM-ring V of the left-hand drive PD, against the contacts 21-22 and 23-5 of the second ring, there is a lamella that is attached to a non-switch P mounted on the hub. Pins 21-22 and 23-24 are paired with each other and they are connected with slots | C and minus from the local battery MB.

On the rear disc ZD on the fourth ring IV opposite the contacts 21-24 of the first ring / there is a lamella attached to the core of the M / Cj correction relay, K to the pin 23 of the first ring / there is a KE correction electromagnet. In parallel with the windings of the non-clamping TlPi relay, the windings of the TR distribution relay, the measles of which, as already indicated above, are connected through the Y switch mounted on the hub, and through the keyboard switch with the back panel slider of the first sector of the hub, turn on. The contacts of the relay relay TP are connected to plus and minus of the linear battery LB (its fault should be the same as the linear battery 1 on the hub).

The plus and minus of the linear battery LB of this set are connected to the contacts of the transmitting relay of the PDR, and the switch of this relay is connected to the eighth spring of the keyboard of the first sector of this set.

Stations operating through a hub do not make any changes to the circuit.

Synchronism and in-phase between sets included in the concentration: retransmission, supported by local correction. The front disk of the hub corrects all the kits included in the hub, and one of these kits corrects the rear hub of the hub. For local correction, a correction relay is installed on each set as well as w on the hub.

The order of switching on the retransmission misocentrator is as follows: terminated

:, Station A (the designation is accepted conditionally but for clarification of the subsequent text) and the interim station (retransmitter-hub) operate between themselves on a two-headed computer: Bodo set. The intermediate station, parallel to the concentrator, carries Bodo headsets that work with other terminal stations directly or through retransmissions.

All connected stations will receive the work of terminal station A,

I like a circular transmitter.

 In addition, through retransmission, the hub can be represented for terminal station A two-way; RONN communication with LEOB from other connected stations.

The subject matter of the invention.

Multiple duplex telegraph retransmission concentrator, providing intermediate communications and transmitting in several directions through terminal multiple duplex telegraph devices, operating in these directions and having in-phase rotation using local correlation, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, with the aim, by the fact, by the fact, with the aim, by the fact, by the fact, in the case, by means of), with the aim, by the way, by the way), with the aim to get in the way, by means of a purpose), by means of a purpose, has to get to this purpose, by means of the project), with the aim to go to the direction, with the help of the local correlation, it is possible to do it. transmissions, I applied two switches for correctional and translational local circuits of the terminal apparatus, connected in the corresponding directions.
