Abstract
437,641. Valve amplifying circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Feb. 26, 1934, No. 27548/35. Convention date, Feb. 25, 1933. Divided out of 439,164 and addition to 410,147. [Class 40 (v)] A resistance 6 is connected in parallel with a coil 5 in series with a resistance 4 in an amplifier for television. The resistance so damps the coil that it does not oscillate at its natural frequency. The circuit elements are so dimensioned that equal amplification of all the frequency band is obtained. The amplifier is used at a transmitter.
