Abstract

351,489. Inductances. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Maneschi, E. ; 46, Avenue de Breteuil, Paris.) March 26, 1930, No. 9641. [Class 37.] In order to minimize side-to-side inductance unbalance on transmission quads, phantom loading coils are constructed so that the number of turns wound on the outer sections of the coils in relation to those wound on the inner sections have an inductance ratio between 1À01 and 1À04. In an example given, the core material has a permeability figure of 110 and inductance ratio 1À025.
