Title: Translating device for telegraph system comprising a two-wire line used for both directions of transmission
IPC: H04L25/04
Filed: 1955-06-22
Abstract: 773,106. Code telegraphy. COMPAGNIE INDUSTRIELLE DES TELEPHONES. June 22, 1955 [June 28, 1954], No. 18037/55. Class 40 (3). In a telegraph system having two stations connected by a two-wire line, each of the wires being allocated to one direction of traffic, a regenerative repeater is automatically connected in accordance with the traffic direction between the two stations by a first pair of relays 2, 3 whose windings are in the lines ab1 and ba1 coming from the stations A, B and a second pair of relays 4, 5 whose armatures are connected to the wires ba2, ab2 leading to the stations and connect the output side S of the regenerator 1 to that wire leading to the station which is not transmitting. In the rest condition of the system positive polarity on the lines ab1, ba1 hold the armatures of the relays 2, 3 in the lower positions and the armatures of the relays 4, 5 engage the contacts shown and, in the alternative condition of the line, the lower and upper contacts respectively. With the contacts as shown, positive potential is passed direct to the line ba2 over the upper contact of relay 4 and to the line ab2 from the lower contact of relay 5 via resistor r1, lower contacts of relays 2, 3 and the regenerator 1. If station A commences transmission, the start signal element moves the armature of relay 2 to its upper position and negative potential passes through the windings 1, 2 of relays 5, 4 respectively, the upper contact of relay 2 and to the input E of the regenerator 1. The regenerated negative pulse passes from the output S to the connection M and over the lower contact of relay 5 to the wire ab2 leading to the station B. When station B commences transmission the start element operates the armature of relay 3 to its upper contact so that negative potential is applied through windings 1, 2 respectively of relays 4, 5, over the upper contact of relay 3 to the input E of the regenerator 1 and to earth. The armatures of the relays 4, 5 are changed over from the positions shown, and the start element is passed from the output S of the regenerator 1 via the lower contact of relay 4 to the line ba2 leading to the station A. The positive impulses the line ba1 from station B operate the armature of relay 3 to its lower position in which positive voltage is applied over resistor r1 to the input E of the regenerator 1 and the regenerated positive element is passed over the lower contact of relay 4 to the line ba2.
