Abstract
437,016. Valve modulating and detecting circuits. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Wheeler, H. A. ; 18, Melbourne Road, Great Neck, New York, U.S.A.) Jan. 18, 1934, No. 23424/35. Convention date, Jan. 30, 1933. Divided out of 436,940. Drawings to Specification. [Class 40 (v)] The subject-matter is identical with that of Specification 436,940. The claims relate to a modulation system and supersonic heterodyne receivers in which one signal is impressed on a control grid of the variable-mu kind to which a variable bias voltage is applied while the second source of oscillations is connected to a second grid in the same electron stream which is screened from the other grid. Specifications 293,462, [Class 40 (v)], 398,882, and 435,383, are referred to.
