Abstract
8032. Strelow, M. March 30, 1910, [Convention date]. [Addition to 21,240/10.] Induction motor meters; power meters.-The core b of the current coils f, g is carried by the core of the pressure coil a, which has a magnetic shunt c and counterpole e as described in the parent Specification, so that the widely distributed part of the flux due to the coil a which traverses the disk returns partly through the core b and partly through the pole e.
