Abstract
487,833. Cathode-ray tubes. MILLER, H., and CAIRNS, J. E. I. Dec. 22, 1936, No. 35131. [Class 39 (i)] In a cathode-ray tube containing a mosaic or like screen on an insulating plate, the other side of which is made conducting to serve as a signal electrode and the whole is carried on a separate supporting member, the face of the supporting member is made conducting and connected to the signal electrode ; this is stated to reduce undesired signals due to relative movement of the screen and supporting member ; to reduce undesired signals due to the motion of the whole the supporting member is connected to the surface of the tube by soft wires. In the arrangement shown the supporting member 3 consists of a mica sheet one portion of which is metallized. The screen 5 is secured to the sheet 3 by mica slips 9 and rivets 10, which do not pass through the metallized portion of the sheet. The metallized portion of the sheet 3 and the electrode forming the back of the screen 5 are connected to each other and to the output electrode by a connection 15. The sheet 3 is supported in the tube by springs 4 and sealing-pieces 16 and are also connected to the wall of the tube by soft wire 8 and seal ing- pieces.
