Claims

Axis extends in the vertical direction (based on claims: the normal orientation of the screen). With such an arrangement of the blue-ray system takes place

1. Blue lateral magnet arrangement for the con - the radial displacement of the blue beam (for the stativergence system of a color picture tube with a, 5 see convergence correction) in the vertical direction. Holder part, which has an opening? .To slide on the central axis radial directions can be rotated by a fourth displacement of the axis offset from the opening, thus adding to the possibility. It can be easily done with a device which, when twisting that all convergence errors are caused in the middle position of one magnetic ring, can be corrected in the same area of the screen if the other magnetic ring is simultaneously corrected by the same amount. individual beam position displacements along the corresponding beam is rotated in opposite directions, thereby characterizing radii by position displacements at right angles to that the mentioned device complements the radial displacement direction of a beam,
It is expedient and common to use the fourth Ver parts (31. 32) of the holder part (30) at right angles to the radial Ver string loop (40), on one side of which there is the direction of sliding for the blue beam to provide one side and the other on the other side, ie that this side or in the horizontal direction

A reduction in the fact that the cord (40) is looped around these bolts is the area of the beam displacement required for the convergence correction and on the two magnetic rings (11, 21), such that both magnetic rings are advantageous when remote thereby the possibility of rotation by equal amounts p. rotated in opposite directions 30 beam distortions or beam spot enlargements. decreased in the corrective beam shift

By rings on the holder part are oriented so that the opposite twisting of the two rings around both noses between the protruding planks will be the same amount of the blue beam in one (31, 32), and that the cord (40) on and at the same time the red and green rays in the opposite sides of the loop shifted laterally in 40 opposite directions,
