Abstract
Abstract The active field producing conductor turns on the inside generally cylindrical core surface of a multilayer toroidal deflection yoke are wound in one direction, e.g., clockwise. The return conductors on the outside of the core are wound in a flyback manner for enabling conductors to be placed in a second layer between the conductors of the first layer for forming a higher conductor distribution density for a first coil or for interleaving the conductors of a second coil between the conductors of the first coil. The two layers may thus be wound over a large angular portion of the core without stopping the winding machine for the cutting or tying of conductors within each coil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A toroidal deflection yoke, comprising: a generally cylindrical hollow flared core; a pair of horizontal and a pair of vertical deflection coils wound toroidally about said core, said coils comprising at least two layers of conductor turns at the small diameter portion of said core and a single layer at the large diameter portion of said core; said conductor being wound over an angular segment of said core to occupy successive conductor receiving portions in a first layer around the small diameter portion of said core and to occupy every other conductor receiving portion in said single layer around the large diameter portion of said core, said conductor being returned along the outside of said core from the end position of said angular segment to a space near the beginning of said segment to form a second layer of conductor turns at the small diameter portion of said core and to lie between said first wound conductor turns at the large diameter portion of said core.
Claim 2
Dependent Claim
166 words
A toroidal deflection yoke, comprising: a generally cylindrical hollow flared core; a pair of horizontal and a pair of vertical deflection coils wound toroidally about said core, said coils comprising at least two layers of conductor turns at the small diameter portion of said core and a single layer at the large diameter portion of said core; said conductor being wound over an angular segment of said core to occupy successive conductor receiving portions in a first layer around the small diameter portion of said core and to occupy every other conductor receiving portion in said single layer around the large diameter portion of said core, said conductor being returned along the outside of said core from the end position of said angular segment to a space near the beginning of said segment to form a second layer of conductor turns at the small diameter portion of said core and to lie between said first wound conductor turns at the large diameter portion of said core.
Claim 3
Dependent Claim
268 words
