Abstract

613,551. Inductances and transformers. LUMALAMPAN AKTIEBOLAG. June 14, 1946, No. 17942. Convention date, June 19, 1945. [Class 38 (ii)] The metal laminations of the core of an inductance or transformer in an electric discharge lamp circuit form the plates of a condenser. They may be metal or metal-coated foil, and wound, piled or folded, if desired in groups. Two iron foil strips 8, 10 separated by paper 9, 11 may be wound into a core of rectangular crosssection which forms the middle limb carrying a choke coil across a rectangular core frame from which it is separated by spacers providing air gaps, Fig. 1 (not shown). Also described are the formation of a shell-type core from alternately arranged E-shaped laminations or groups of laminations with overlapping limbs, Figs. 3-5 (not shown), and cores of folded foil, Figs. 6 and 7 (not shown).
