Abstract

326,984. Gramophone Co., Ltd., and Bailey, C. E. G. March 7, 1929. Thermionic amplifiers.-In a wireless circuit comprising two. or more tunable oscillatory circuits wherein a portion only of the inductance 1 in one of the tunable circuits is included in the circuit between the earth and aerial a condenser 12 is shunted across a portion only of the inductance 7 in the other tunable circuit. The condenser 12 is preferably variable and shunted across the same amount of the inductance 7 as the amount of inductance 1 in the aerial circuit. The tuning controls for the tunable circuits are preferably interconnected.
