Abstract

1288447 Transformers and inductors JOHANN BERNDEISEL & CO 30 April 1970 [30 April 1969] 20971/70 Heading HIT A transformer or choke core comprises E or U-shaped laminations 1 having the free ends of its outer legs wider than the bridge, a clamping member 10 pressing further core laminations 3 inwards to force an insulating strip 8 against the centre limb 2 of the E-shaped portion or through a cross-shaped core portion 20 (Fig. 3) against the base of the U-shaped portion. The choke may have two separate windings 18, 19.
