Abstract

476,947. Cathode - ray tubes. BAIRD TELEVISION, Ltd., MERDLER, L. R., and TINGLEY, G. R. June 18, 1936, No. 16979. [Class 39 (i)] Deflecting - means for an electron-discharge device comprise a pair of coils disposed within a hollow substantially cylindrical member of ferromagnetic material divided by one or more axial slots. The coils 1 may be made to conform to the neck 2 of a cathode-ray tube and are arranged within a ferro-magnetic cylinder 3, which is divided by two axial slots into two substantially equal semi-cylindrical parts, which are electrically insulated from one another. The cylinder 3 may take the form of small rectangles of ferro-magnetic material fastened to an adhesive tape and arranged round the device 2. The cylinder may be of such length as to include wholly the coils 1 or may be of the length shown. It is preferably formed of high permeability material, such as that known under the Registered Trade Mark " Mumetal."
