Abstract
Abstract The deflection system yoke for a television receiver cathode ray tube includes saddle shaped coils having a plurality of windings arranged in strands along the neck of the tube. The strands are achieved during the winding procedure by introducing starting points for the first winding of each strand. All strands together form a rigid unit.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
A method of winding a saddle shaped deflection coil comprising: a. providing a mandrel having a recess, whose shape corresponds to the final shape of the coil, for receiving continuously applied coil turns of wire; b. continuously applying coil turns of wire into said recess to wind the saddle shaped deflection coil; c. during said step (b), inserting projections at predetermined positions into the recess after applying a predetermined number of coil turns to provide predetermined starting points for the subsequently applied coil turns; and d. heating the completed coil prior to removing same from the mandrel for obtaining a self-sustaining unit.
Claim 2
Independent Claim
