11,695. Wise, W. L., [Union Elektricitõts- Gesellschaft]. June 27. Energy meters. - An induction motor meter, for a single alternating current, has two or three straight electromagnets M, placed parallel to the spindle S, and driving two conducting - discs F<1>, F<2> thereon. One electromagnet carries the main current, the other being connected between the mains, when two magnets are used ; when three are used, the outer ones are connected alike. In order that the magnetic fields produced by the shunt current may be in quadrature with those produced by the main current, a bent wire or solid iron bar is fixed with its ends E', E<3> near those of the shunt electromagnet, the discs intervening. The bar is fixed in a sleeve f, after adjustment. An air gap may be provided in the bar. The ends of the bar may be formed as loops, as shown in plan in Fig. 3.
