Abstract

229,881. Edgcumbe, K., Everett, E. I., and Ockenden, F. E. J. March 24, 1924. Transformers.- A transformer for use with instruments for measuring currents of radio frequencies comprises an annular core a, on which the secondary winding b is evenly distributed, and a primary winding c consisting of a hollow tubular member passing through t h e open in the core and a concentric return member surrounding the secondary winding and core.
