Abstract
463,676. Screens foi high - frequency coils. FODOR, G., TOUTAIN, J., and BLOCH, M. March 17, 1936, No. 8025. Convention date, Oct. 17, 1935. [Class 38 (ii)] A screen 2 for high. frequency coils comprises a copper or aluminium cylinder having an electrical discontinuity extending along its length. The discontinuity is formed by introducing insulation 6 between overlapping edges of the screen material.
