Abstract
468,364. High - frequency transformers. MICHAELIS, E. Dec. 30, 1935, No. 36007. Convention date, Dec. 28, 1934. [Class 38 (ii)] [Also in Group XL] A high - frequency iron-core tuned transformer comprises two separate oscillatory circuits, the coupling between which is adjustable, each unit comprising an insulating plate a on which a preset condenser c is mounted, and a cup-shaped member b within which is mounted a twopart iron core o<1>, o<11>, and coil former and winding q kept in position in the cup by a resilient plate x. The two units are mounted in a screening cup f by screws m, n, k, and their coupling is adjustable by sliding in slots g, h.
