Abstract
1,015,456. Transformers; current assemblies. PLESSEY COMPANY (U.K.) Ltd. June 26, 1964 [June 27, 1963], No. 25676/63. Headings H1R and H1T. [Also in Division H3] A coil assembly comprises two coils 11, 12 (Fig. 1) wound at rightangles to each other on a former 10, in order to minimize the mutual inductance between them, and a ferro magnetic core member (not shown) which can move through the former 10 to vary simultaneously the coil inductances. The core member may be a ferrite. The windings 17 of the coil 12 are printed on a flexible substrate 14 (Fig. 2) provided with an aperture 19 through which access into the former 10 by the core member is made after the printed substrate 14 has been bent along the lines 19 into the shape shown in Fig. 1 and around the former 10. The ends of the windings 17 are soldered together to complete the coil and the winding 11 is secured around the coil 12 by adhesive. In an alternative embodiment (Fig. 6, not shown) the winding 15 of the coil 12 is formed as a continuous track on the substrate in order to remove the necessity of soldering the winding ends. Further ferromagnetic members extending parallel to the winding 11 may be attached to the coil assembly (Fig. 7, not shown).
