Abstract
440,106. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. June 20, 1934, No. 18204. Convention date, June 27, 1933. [Class 39 (i)] A tube for producing large television images (greater than 9cm. by 12cm.) has magnetic means for the image deflection and electrostatic means for the line deflection. The plates and the electrostatic systems may be tilted in relation to each other. In one form a coil 3 creates the image deflection and a pair of plates 4 the line deflection. The plates 4 are spaced from the screen 2 by a distance of 20cm. to 30cm. or more, giving images greater than 10cm. by 15cm. An electrode 5 at a positive potential relative to the anode acts as an electron return flow intercepter, whilst a metallic wall coating 6 is at anode potential. The filling may have a pressure of less than 10<-6>cm.
