Abstract

1466878 Transformers and inductors H HIRST 21 Feb 1974 8050/74 Heading HIT The subject-matter is related to that of Specification 1,466,879 namely E and I members for laminations having specific proportions and size ranges except that the length of the limbs of the E-member must be greater than 3x and preferably not greater than 5x, thereby giving rise to some wastage of material during manfacture.
