Abstract
496,812. Cathode - ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, and ANDRIEU, R. May 3, 1937, No. 12557. Addition to 433,996. [Class 39 (i)] The deflecting coils S according to the parent Specification do not extend over the whole of the tube being omitted at the parts A to improve focus. In manufacture a flat coil is formed and then is Lent over a cylinder 12, Fig. 3, of stiff paper with spacers 13 ; this can then be applied to the tube.
