Abstract
412,895. Valve detecting circuits. MEINESZ, J., 37, Broomwater, Teddington, Middlesex. March 2, 1934, No. 6712. [Class 40 (v).] Two valves V1, V2, neither of which acts as a detector in itself, are connected for push-pull operation and are stated to detect highfrequency oscillations if their anodes are connected directly, by a low-frequency transformer, a high-frequency choke or a tuned circuit. The detected signal is applied to an amplifier V3. When a low-frequency transformer is used to connect the anodes, the low-frequency amplifier consists of two valves in push-pull fed from the secondary of the transformer (Fig. 2, not shown).
