Abstract

235,920. Kulikoff, A. June 23, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Magnetic instruments.-In a telephone receiver an armature A is positioned between two pairs of pole-shoes and connected to a diaphragm. The coils (not shown) are wound so that the current takes the direction of the arrow, or its opposite. The magnet N, S may be a permanent or an electromagnet.
