Abstract

720,323. Electromagnets. ULTRA ELECTRIC, Ltd. March 30, 1953 [May 22, 1952], No. 13005/52. Class 35. The poles of an electromagnet or its armature are so shaped that the air-gap length remains fixed while the amount of overlap of the pole-faces varies in a non- linear manner to produce a desired characteristic. In the pot-magnet shown, the annular armature c has a pair of tapered poles d. In a modification, an E-shaped electromagnet acts on a C-shaped armature having tapered limbs.
