Title: A cathode ray tube
Inventor: SLUIJOTERMAN ALBERTUS AEMILIUS
IPC: H01J29/56
Filed: 1981-12-05
Granted: 1988-09-27
Abstract: The deflection units, when energised, produce dynamic multipole fields which are strongly modulated.  Such modulation may be achieved by the use of static magnetic multipole arrangements, since a static n-pole magnetic field simulates, for a charged particle passing eccentrically through it, a dynamic (n-2) pole field.  A deflection unit has field coils and line coils, includes a static 8-pole field produced by two tangentially magnetised magnets and four radially magnetised magnets.  Higher and lower order multipole fields may be suppressed by suitable dimensioning and shaping of the magnets.  The permanent magnet device has an annular member of permanent magnetisable material which is provided coaxially with the longitudinal axis of the unit.

Abstract: A centrifugally operated clamping device for clamping a reversible blade insert in a planing tool ensures positive engagement between the clamp and the blade. The clamping device includes a clamping wedge which has an inverted T-shaped cross-section and is positioned in a similarly configured groove in the tool. The wedge is biased relative to the bottom of the groove so that the clamp will be easily disconnected from the blade.
