Abstract
770,166. Transformers and inductors. STANDARD TELEPHONES & CABLES, Ltd. Oct. 26, 1953 [Oct. 28, 1952], No. 29511/53. Class 38(2). [Also in Groups XL (b) and XL (c)] Coils and transformers for the intermediate - frequency stage of a microwave receiver comprise spiral strips 72, 74, 93, 94, 97 of conductive material disposed on either side of a sheet 57 of insulating material. The two spirals 93, 94 are on opposite sides of the sheet and overlap to provide a transformer coupling. The conductive strips may be printed on the dielectric sheet. Specifications 704,050, 708,598, 708,600, 708,601, 722,660, 726,067, [all in Group XL. (b)], are referred to.
