Abstract

633,625. Making electric components. BULL, E. W., and HOLMAN, H. E. June 22, 1946, No. 18802. [Class 83 (ii)] [Also in Groups XXXV, XXXVI and XL (a)] A coil is made by embedding or otherwise securing one or more conductors arranged to provide one or more convolutions in an insulating support which is then bent to arcuate or cylindrical form, the effective parts of the conductors preferably being parallel to the axis of the arc or cylinder. As shown, grooves are made in an insulating sheet 1 by engraving, moulding or pressing and are filled with metal, e.g. by electro-plating to form turns 2, the sheet then being bent into cylindrical form and applied to the neck of a cathode-ray tube. Alternatively, a sheet of conducting foil may be applied to the sheet 1 and the superfluous metal etched away by acid. As an alternative, wire could be bent to the configuration shown and then secured by adhesive to the sheet 1, or the turns could be disposed about pins disposed on a metal former to which sheet insulation, e.g. polystyrene, could then be applied to embed the turns. In yet another form, a pattern of the desired coil turns is printed in conducting material on a support of ceramic material which is then fixed to fuse the conducting material. Specifications 233,050, [Class 36], and 449,533, [Group XXXV], are referred to.
