Abstract

774,401. Electron beam deflecting apparatus. PYE, Ltd. May 5, 1955 [May 10, 1954], No. 13555/54. Class 39(1). The inductance of the deflecting coils is adjusted without affecting the uniformity of the deflecting field by surrounding a portion of the coil e.g. the end turns 1c of a saddle-type coil, with a magnetic path of variable reluctance such as U-shaped member 5 and variable armature 6. The members 5, 6 may be ferrites.
