  • Patent number: 4376924
    Abstract: A self-converging color television display system utilizes a saddle-toroid deflection yoke. The length of the horizontal coil conductors adjacent the flared picture tube portion is limited to reduce stored energy. The length of the core also is limited and disposed longitudinally between the end turns of the horizontal saddle coils at a position to mitigate convergence trilemma as well as North-South pincushion distortion.

  • Patent number: 4128824
    Abstract: A deflection yoke comprises a core and at least two layers of conductor turns wound about the core. A return traverse conductor traverses the core from a finishing conductor turn of one of the layers to a starting conductor turn of the other layer. At least three projections are located adjacent an outer surface of the core for providing pivot points for the return traverse conductor. A first projection is located near a starting conductor turn of one of the layers, a second projection is located near a finishing conductor turn, and a third projection is located between the first and second projections for preventing the return traverse conductor from protruding beyond a core end.
