Abstract

550,577. Magnetic dust cores. ACES DEVELOPMENT CO., Ltd., and FRIEDLANDER, E. R. Oct. 16. 1941, No. 13305. [Class 38 (ii)] [Also in Group V] A mushroom-shaped magnetic core for high frequency work made from insulated magnetizable particles is manufactured by first forming a pellet m of a diameter slightly less than the smaller diameter of the finished core and then submitting the pellet together with additional insulated powder n to pressure in a die or mould. The Figure shows how pressure is applied by a punch o and the finished core ejected by a pin l.
