Description

Дл  усилени  слабых вход щих токов при междугородном телефонировании потребовалось бы поставить катодные усилители на конечных аппаратах, а потому при разговорах абонентов с квартир следовало бы поставить усилители у домовых аппаратов абонентов, что, конечно, по многим причинам неудобно. Практически было бы удобнее сосредоточить эти усилители на междугородних станци х, применив соответствующие схемы с искусственными лини ми. На фиг. 1-3 изображены предлагаемые схемы телефонной трансл ции одностороннего обратного действи . По схеме фиг. 1 ток городской или межгородной линии (МЛ) проходит через обмотки 1.1. трансформаторов (Гз) и (Ti) входного контура катодного усилител  (Kz) и выходного контура катодного усилител  (/fi), остальные контуры которых св заны при помощи трансформаторов (Ti) и (/2) с дифференциальным мостиком, составленным из телефонной линии и искусственной линии(Л),при чем, идущие по обмоткам 2 - 2 трансформаторов (Ti) и (Т ) токи будут равны и противоположно направлены, а потому не будут действовать на сетку катодного усилител  (Лз)- Таким же путем будет действовать и схема фиг. 2, котора  отличаетс  от предыдущей тем, что обмотки 2-2 трансформаторов (r.i) (7j) намотаны на трансформаторы (Гз) и (Ti). Ток, развиваемый в обмотке 2-2 трансформатора (Тз), по схеме фиг. 3, проходит через обмотку 2-3 трансформатора (Т4) в направлении противоположном току обмотки 1-1 трансформатора () и уничтожает его вли ние на обмотку 4-4 сетки катодного усилител  ()Телефонна  трансл ци  одностороннего обратного действи , характеризующа с  тем,чтооднателефонна  лини  ПРЕДМЕТ ПАТЕНТА.In order to enhance weak incoming currents during long-distance telephony, it would be necessary to install cathode amplifiers on the final devices, and therefore, when talking to subscribers from apartments, you should install amplifiers for subscribers' home devices, which, of course, is uncomfortable for many reasons. In practice, it would be more convenient to focus these amplifiers on intercity stations using the appropriate circuit with artificial lines. FIG. 1 to 3 depict the proposed one-way reverse telephony translation schemes. According to the scheme of FIG. 1 current urban or long-distance line (ML) passes through the windings 1.1. transformers (Gz) and (Ti) of the input circuit of the cathode amplifier (Kz) and output circuit of the cathode amplifier (/ fi), the other circuits of which are connected with the help of transformers (Ti) and (/ 2) with a differential bridge composed of a telephone line and of an artificial line (L), with it, 2-2 transformers (Ti) and (T) running along the windings will be equal and oppositely directed, and therefore will not act on the cathode amplifier grid (Lz) - The same way will act FIG. 2, which differs from the previous one in that the windings 2-2 of the transformers (r.i) (7j) are wound on the transformers (G3) and (Ti). The current developed in the winding 2-2 of the transformer (Tz), according to the scheme of FIG. 3, passes through the winding 2-3 of the transformer (T4) in the direction opposite to the current of the transformer winding 1-1 () and destroys its effect on the winding 4-4 of the cathode amplifier grid () Telephone translation of one-way reverse operation, characterized by the fact that LINE ITEM PATENT.
