Abstract (en)

[origin: US4812946A] A device for demagnetization of the picture tube of a television receiver and earthing of the conductive coating applied to the cone of the tube includes a demagnetization coil system (4) constituted by a bundle of insulated electric wires held together and forming at least one loop applied to the cone of the tube. The wires of the strand are held together by a tape of plastic material wound helically around them, while a bare electric wire (1) is wound helically with the same pitch as the tape. This wire is connected to earth (15, 16).
