Abstract: 615,553. Magnets. KOLSTER-BRANDES Ltd., and LOCK, C. E. Feb. 27, 1946, No. 6138. [Class 35] [Also in Group XL (a)] An adjustable focusing device for a cathoderay tube consists of an annular permanent magnet 1 clamped between front and back plates 2 and 3 of magnetizable material by means of screws 4 (Fig. 2) of non-magnetic material, e.g. brass, and a sleeve 6 of magnetizable material provided with a knurled flange 7, screwed through the centre of the back plate 3, forming together with the front plate 2 the polepieces of the magnet. The sleeve is locked in position by means such as a spring 8. The device is supported by a resilient e.g. rubber ring 11 (Fig. 1) supported by a fixed plate 14. The ring is secured to the plate by means such as three mushroom-like projections 13 whose heads are forced through corresponding holes in the plate.
