Abstract

348,807. Inductances. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Detar, D. R. ; R.D.1, Schenectady, New York, U.S.A.) April 2, 1930, No. 10484. Convention date, April 16, 1929. [Class 37.] An adjustable inductance comprises axially spaced winding sections 6, 6<1> and means on the former 5 located in the space between the winding sections for transferring turns from one section to the other without altering the total effective turns. As shown, a split ring 11, which may be a portion sawn from the former, is located between the sections and the winding is passed through the slit 9 as the ring is axially moved. Inductances as described are employed in multiple tuned circuits, any difference in the individual circuits being readily adjusted and the final position of the slider being sealed by wax &c. 14.
