Abstract: 1330688 Electron beam magnetic deflecting systems LICENTIA PATENT-VERWALTUNGS GmbH 21 Oct 1970 [28 Oct 1969] 49957/70 Heading H1D In a magnetic deflecting system for a television receiver tube, astigmatism can be corrected by means of auxiliary coils disposed on the deflection yoke extending over an angle alpha with respect to the deflection axes and fed with current at one scanning frequency modulated by the other scanning frequency; the number of ampere turns required and the direction of current flow are functions of alpha (Fig. 2, not shown), and there is an intermediate range of values of alpha where the coils have little effect. Distortion of the raster due to screen curvature may also be corrected by the auxiliary coils (Fig. 3, not shown). According to the invention the angle alpha is selected so that the auxiliary coils correct for distortion, and the ampere turns are selected to correct for astigmatism. If the screen curvature is such that the distortion cannot be corrected entirely by selection of the angle alpha, the distortion may be corrected by means of further auxiliary coils disposed in the intermediate range of values of alpha where they have little effect on the astigmatism.

Abstract: A process for producing silicon steel sheet having the (100) plane in the rolling plane comprises taking an ingot of 2.0-4.0% Si, 0.010-0.150%C, 0.010-0.060% acid soluble Al, inevitable impurities, and the balance Fe, rolling the ingot to a slab, hot rolling the slab in arc direction at a temperature between 800 DEG  and 1250 DEG C. with a reduction of greater than 20%, hot rolling in a direction at right angles to the pivot direction at a temperature of at least 600 DEG C. and with at least 40% reduction, and cold rolling and annealing the sheet to produce recrystallization grains having (100)[001] and (100)[011] orientation.  In an example a 500Kg ingot containing 0.045%C, 3.02% Si, and 0.030% acid soluble Al was bloomed longitudinally to form a 100 mm thick slab, the slab was soaked at 1250 DEG C. for 30 minutes, cross rolled to 30 mm thickness, and again hot rolled after turning through 90 DEG C. to form a 3 mm thick sheet, the temperature then being 750 DEG C.  After annealing at 950 DEG C. for 5 minutes, and pickling, the sheet was cold rolled in the same direction as the final hot rolling to 1.08 mm, decarbonized in wet H2, annealed in a N2-H2 atmosphere at 1200 DEG C. for 20 hours, cold rolled to 0.32 mm., and finally annealed in H2 at 1200 DEG  for 20 hours to produce a double-oriented silicon steel.
