Abstract

578,218. Inductances. IMBER, J., and ALADDIN RADIO PATENTS, Ltd. Sept. 28, 1944, No. 18613. [Class 38 (ii)] An iron dust core for an electrical inductance comprises a plain cylindrical core element a having applied to its surface an impressionable material b which receives an impression of a screw thread e when it is inserted into a former d so that it is afterwards adjustable in position by screwing it in or out. Slots to take a screwdriver may be formed in the core ends. The coating b which may cover the core surface, or be applied as one or more longitudinal strips, may be of plastic tape, paper or textile material with or without an adhesive coating.
