Abstract

445,998. Transformers ; inductances. JOHNSON LABORATORIES, Inc., 609, West Lake Street, Chicago, U.S.A.-(Assignees of Neighbors, C. C. ; 11, North Long Avenue, and Meinema, H. E. ; 2312, West 108th Place, both in Chicago, U.S.A.) Oct. 27, 1934, No. 30706 /35. Convention date, Nov. 11, 1933. Divided out of 441,727. [Class 38 (ii)] [See also Group XXXVI] A core for a high-frequency transformer or inductance comprises a thick-walled tube of comminuted magnetic material the length of the tube being at least equal to the external diameter, and the diameter of the bore being not greater than one third of the external diameter. The core may be mounted on an insulating frame as described in Specification 441,727.
