Abstract

1389423 Colour television tubes RCA CORPORATION 23 May 1972 [14 Jan 1972] 1779/72 Heading H1D The deflection yoke of a colour television tube is loosely supported round the tube whilst the tube is operated, adjusted transversely of the axis to obtain coincidence of the rasters of the three colours, and then fixed in position relative to the tube. When the tube uses three co-planar beams and a deflection yoke adapted to produce a barrel-shaped vertical deflection field and a pin-cushion-shaped horizontal deflection field, a dynamic convergence system may be unnecessary if the yoke is adjustable transversely since such adjustment can correct for errors in registration caused bv misalignment of the electron gun within the tube, misalignment of the deflection yoke, or asymmetry of the deflecting coils.
