Abstract

466,497. Valve circuits for wireless reception. ROBINSON, J. Nov. 27, 1935, No. 32940. [Class 40 (v)] In a receiver for modulated signals reaction through one or more mechanically resonant selective devices is employed so that substantially only the carrier frequency is amplified and stability ensured. Phase controlling means may additionally be provided in the reaction circuit. The Figure shows a piezoelectric crystal 24 in the feed-back circuit the self capacity of which is neutralized by condenser 26 which may additionally be used as a phase adjuster. Specifications 243,765, 251,588, and 258,707, [all in Class 40 (v)], are referred to.
