Abstract

440,085. Inductances. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. May 13, 1935, No. 14000. Convention date, May 29, 1934. [Class 37] In a laminated iron core for a choking coil, the laminµ 3 are separated by independent or separate sheets 4 of insulating material, such as oiled fabric. Cover plates 6, 7 of insulating material are held at a definite distance apart by means of non-magnetic distance pieces, such as insulating sleeves 8 through which pass the bolts holding the laminµ together.
