Abstract

391,521. Transformers. HAZELTINE CORPORATION, 15, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Mac Donald, W. A. ; Little Neck, New York, U.S.A.) Nov. 21,1931, No. 32329. Convention date, Feb. 13. [Class 38 (ii).] A transformer for use in superheterodyne radio receivers comprises coils 152, 153 spaced apart on an axial former 159 and closely surrounded by a metal cylinder 162 which reduces the coupling between the coils to a desired value.
