Abstract
615,477. Transformers and inductances. PHILIPS LAMPS, Ltd. May 17, 1946, No. 14973. Convention date, April 29, 1940. Drawings to Specification. [Class 38 (ii)] [Also in Group XXXVI] A conductor such as a metallic plate, coil or straight wire which may be of constantan or iron, or a conductively-coated insulator, retains an inductance of high value at frequencies exceeding 10<SP>9</SP> by virtue of the provision on the surface of the conductor or insulator of a layer of ferromagnetic material of such nature that it presents a metallic appearance even under strong magnification. The coating may be applied by electrolysis, a suitable example of which is described (see Group XXXVI), by cathodic disintegration, or by electrophoresis, as described in Specifications 226,531 and 325,317, [both in Class 41]. One or more coated supports may be incorporated in a core or a coated wire may be used as a loaded conductor. Specification 238,559, [Class 38 (ii)], also is referred to.
