Abstract

443,270. Wireless receiving-apparatus. 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.) Sept. 25, 1934, No. 4810 /35. Convention date, Oct. 3, 1933. Divided out of 430,787. Drawings to Specification. [Class 40 (v)] The subject-matter is identical with that of Specification 430,787. The claims relate to the detecting arrangement for obtaining gain controlling voltage and ensuring that this voltage is withheld from the amplifiers while it is positive with respect to the cathodes of the amplifiers and obtaining a reverse gain control voltage to increase the gain control. Reference has been directed by the Comptroller to Specification 407,317.
