Abstract

684,446. Transformers. ESSWEIN, J., and HENRY, G. Dec. 29, 1950 [Feb. 28, 1950], No. 31652/50. Class 38 (ii). An ignition coil comprises a central magnetic support 21, on which is wound a secondary winding 22 surrounded by an insulating casing 23, the primary winding 25 being wound on a spool 24 and placed around the casing 23. The casing 23 is filled with oil or a similar substance and the whole assembly surrounded by a corrugated magnetic member 26 which serves to increase the rate of heat dissipation of the primary winding and also to form part of the magnetic circuit of the coil. The separation of the primary and secondary windings by a casing comprised of a poor heat conducting substance reduces the effect of the heat produced in the primary winding on the insulation of the secondary winding.
