Title: Improvements in or relating to electromagnetic deflecting coils for cathode ray tubes
IPC: H01J29/76
Filed: 1936-09-21
Abstract: 482,195. Cathode - ray tubes. BLUMLEIN, A. D. Sept. 21, 1936, No. 25574. [Class 39 (i)]. Horizontal and vertical deflections are produced in a cathode-ray tube by a single winding having two pairs of tapping points so arranged that a current passing through one pair of tapping points produces a field at right-angles to a current passing through the other pair. The Figure represents an arrangement of a winding having eight coils the pitch of each coil being <7>/16 of the circumference. Current entering and leaving through the tappings TL traverses coil sides marked with a dot upwardly through the plane of the paper and those marked with a cross downwardly ; current passing through the tappings JF produces a field at right-angles to the other. The coil may be surrounded by an iron core, which to render the field more uniform, may have a somewhat square cross-section somewhat more distant from the coil sides 1<1>, 2, 31, 4, 5<1>, 6, 7<1>, 8 than from the others. Another method of making the field more uniform consists in making the pitch of the coils <5>/16 of the circumference with the result that in one pair of coil sides 180 apart the current is flowing in the opposite direction to that in the adjacent sides.
