What about the flangeless technology - is that not part of the 30AX technology? The patent abstract says:

30AX is a new in-line color TV display system with 110 deflection angle and interchangeable tubes and yokes. It is based on the production experience gained with the 20AX system introduced in 19741,2,3) and the results of further investigation in the field of tube technology and deflection yoke design. For the tube, this meant a new reference system, an internal magnetic correction ring and an improved gun design. For the yoke, the most important elements are a new "flangeless" winding technology, a change in the shape of the windings at the screen side of the line deflection coil and the use of field shapers embedded in the deflection coil.

There are surely elements of 30AX technology there - are there not? The external magnets are not the whole story - it's more complicated than that.
