Abstract

761,814. Electromagnets. RADIO CORPORATION OF AMERICA. June 2, 1954 [June 25, 1953; Sept. 30, 1953], No. 16328/54. Class 35. [Also in Group XL (a)] An electromagnet for deflecting a beam of a multiple beam colour television tube (see Group XL (a)) comprises an E- shaped core 76 coupling with pole pieces 70, 72 within the envelope. Other magnets described have a U-shaped core outside the envelope and within the envelope plate-shaped pole-pieces extending radially of the tube axis. Permanent magnets may be used.
