SU771A1 - Telephone translate - Google Patents

Description

The proposed translations are based on the already known schemes between the author's original devices with differential telephones or differential transformers. The transition from these circuits to parallel-connection translations is accomplished by the following manipulations: the linear terminals of the circuit are connected in parallel to the line; each winding of a differential telephone is replaced by a grid of a particular amplifier, either directly or by a skull through a transformer; the anode circuits of the two above-mentioned amplifiers connect each with a special primary winding o6niero differential transformer, wherein the anode circuit lamps work towards each other; the secondary winding of the designated differential transformer is included in the grid circuit of the third amplifier; the anode circuit of the third amplifier is connected to the primary winding of the microphone transformer.

FIG. 1 depicts an exemplary long-distance service scheme underlying the translation, FIG. 2 shows a complete translation scheme of parallel connection; FIG. 3 is a flow chart of sequential switching without an artificial line, and in FIG. 4 shows a serial transmission scheme with artificial lines. By producing these manipulations, a parallel inclusion translation scheme is obtained, according to FIG. 2nd: both wires Z, J and Z are connected in parallel to the winding, 2 transformers of the winding 3, 3 of the transformer 7) are included in the grid circuit of one of the lamps of the amplifying circuit, / and / C) 2, consisting of two connected opposite friend bulbs; the winding l, i of the transformer T is included in the output iiiofi circuit of the cathode QUS relay, in series with the winding i, 1 of the transformer 7.,; winding 3, 3 of transformer T-2 is included in the grid contour of the second cathode lamp of the amplifying circuit and winding 2, 2 of transformer T- is included in an artificial line, the output contour of the 1ltl1 control circuit of the remote control and connected to the input circuit of the relay / vy .V.

In the resulting translation scheme, an artificial line is replaced by one line part, and the whole line is replaced by another line segment, the translation scheme of a sequential connection without an artificial line is obtained, as shown in FIG. 3: at that, one of the lines is connected to winding 2. At Л1П1е (transformer Т Т, and the second line is included, instead of artificial one, in winding 2, 2 of transformer / о.

 Two external circuits of FIG. The 2nd and connecting the anode center of the last amplifier of one of the circuits with the linear transformer of the other circuit, and vice versa, a series-wise transfer circuit is obtained with the artificial coiviacHO lines of FIG. 4: the anodic circuit of the output amplifier AU. The translation is connected to the telephone line i, Z.2 by windings /, I and i, 2 of the transformer 7}; winding 5,. transformers 7 and T} are connected to the input circuit of the same translation, with the line L-L, turning on the windings 2, 2 of the output transformer 7 of the last translation; the grid winding of one of the lamps of the amplifier circuit KU I and / SU of the red translation is included in the winding of the transformer T

By the methods already known by the author, these broadcasts can be applied to switch from conventional telephony to wireless telephony or telephony with fast alternating currents, and also as central amplifiers.
