Abstract

1339881 Colour cathode ray tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Sept 1972 [21 Sept 1971] 43078/72 Heading HID The deflecting coils of a colour cathode-ray tube producing deflection in at least one direction are divided by at least one tapping and some or all of the sections so defined are connected in parallel with a respective adjustable impedance. The coils deflecting the beam in one direction can be connected in series, Figs. 6a, 6b (not shown), or in parallel, Fig. 7a, 7b (not shown), and in the latter case corresponding sections can share a single adjustable impedance. The adjustable impedances are preferably coils and resistors for the horizontal and vertical deflecting coils respectively. The impedances are used to adjust the convergence of the beam after assembly.
