Abstract
580,860. Discharge apparatus. BROADWAY, L. F. March 9, 1944, No. 4448. [Class 39 (i)] In a cathode ray tube in which the electron beam of the tube is of elongated form in crosssection and is caused to converge to form a small spot on the screen and in which two sets of deflecting electrodes are provided to deflect the beam in two different directions, one of these sets is disposed at a position where the beam is of elongated form and embraces the longer sides of the beam cross-section. As shown electrons from a cathode 2 are formed into a beam of elongated cross-section by slotted electrodes 3 and 8 and an intermediate electrode 5 and deflecting means 10 are provided embracing the longer sides of the beam. Specification 574,056 is referred to.
