Abstract

1,178,234. Electron beam magnetic deflecting apparatus; printed circuits; coils. ELECTRIC & MUSICAL INDUSTRIES Ltd. 14 Feb., 1967 [26 Feb., 1966; 22 Dec., 1966], Nos. 8555/66 and 57342/66. Headings H1D, H1P and H1R. A printed electrical circuit for use as line and field scanning coils in c.r.t's, particularly vidicon camera tubes for example, comprises a flexible insulating base 1, printed conductors 2, 3 in the form of two similar waves, preferably square waves, extending longitudinally along the base in two portions which may be folded about X-X the resulting strip being wound into cylindrical form to produce a saddle-type scanning coil. The interconnecting conductor portions at at least one end of the waveforms are skewed (Fig. 3, not shown) so as to allow for the differing diameters of inner and outer portions on winding into cylindrical form and so reduce surface wrinkling. An insulating sheet placed between the two portions prior to folding prevents short-circuiting of the overlapping portions. Printed copper register strips 7 with punched locating holes improve accuracy of winding while electrostatic screens. 8 of finely drawn wires reduce eddy currents between the coils.
