Abstract

462,684. Electromagnets. GILBERT, A. H., MERDLER, L. R., and BAIRD TELEVISION, Ltd. Sept. 12, 1935, No. 25386. [Class 35] [Also in Group XL] An electromagnet for deflecting the electron beam in cathode-ray tubes has adjustable polepieces 4. The polepieces are loosely riveted or bolted at 5, to the U-shaped core 3, which is made of straight elements. The limbs of the U - member may also be pivoted at 6 to the base which preferably carries a single magnet coil 2.
