Abstract
380,689. Current meters. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Jan. 20, 1932, No. 1779. Convention date, Feb. 13, 1931. [Class 37.] An arrangement for indicating inequality in the strengths of two high-frequency currents in two aerial feed circuits comprises coupling elements L3, L4 respectively arranged in said circuits and feeding angularly spaced coils L5, L6 in the field of which a rotatable pick-up coil L7 is 'arranged which is connected to a valve-voltmeter R. When the two feed currents are of the same strength the coil L7 is set to give a certain deflection on the voltmeter indicator. Variations of this deflection indicate inequality in the two currents.
