Abstract

498,150. Magnetic cores. SIEMENS & HALSKE AKT.-GES. July 30, 1937, No. 21220. Convention date, July 31, 1936. [Class 38 (ii)] Dust cores for inductance coils are prepared using as the binder a polymerized material, the molecule of which is substantially a onedimensional chain but which has attached to the chain strongly polar groups such as chlorine, nitrogen, hydroxyl or carboxylic ester groups. Suitable polymeric materials are polymerized acrylic acid esters or polymerized vinyl compounds containing chlorine or nitrogen. Specification 418,096, [Group IV], is referred to
