Abstract

1,211,724. Aerials. LTV ELECTROSYSTEMS Inc. 3 Nov., 1967 [9 Dec., 1966], No. 24662/70. Divided out of 1,211,723. Heading H4A. The description is similar to that in the parent Specification but the claims relate to an aerial in which slotted electrically conductive discs 8, Fig. 3, which may be made of aluminium, are placed over the core sections, between coils and adjacent end-pieces, in order to reduce air coupling of fluxes between the coils.
