IPC: H01J9/20
Filed: 1954-06-11
Abstract: 767,139. Cathode ray storage tubes. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1954 [June 15, 1953], No. 17291/54. Class 39(1). An insulating mesh screen of solid strands of insulating material is manufactured by depositing silicon monoxide on one side of strands of a metal mesh screen, dissolving away the metal mesh screen and heat treating the insulating mesh screen for 18 hours at a temperature of 600-800C. In one form a nickel or copper mesh, preferably the former, is applied to a metal ring 1, Fig. 1, a second metal ring being placed on top and the parts being welded together. The assembly is heated in hydrogen at 1400F. for 20-30 minutes and cooled for 45 minutes to make the mesh taut and flat. Silicon monoxide is now evaporated on to one side of the nickel mesh from a reaction mixture contained in an electrically heated tantalum boot. The structure is now placed on a fired lava disc 8, ring 1 fitting on cut away portion 7 and a filter paper 10 is placed against the nickel mesh and wetted with distilled water. The ring 1 is cut away with a scalpel and a stainless steel mesh 1 is placed on filter paper 10. On immersion in dilute HCl or HNO3 e.g. 10 per cent HNO3 the nickel is etched away leaving the silicon monoxide mesh. The structure is rinsed in tap water, mesh 11 is removed, and after rinsing in distilled water a quartz or fired lava disc is placed against the filter paper and the structure is dried at 50C. for one hour. The structure is then heated to about 700C. in an oxidizing atmosphere and held there for 18 hours, then cooled slowly in the oven to 100C. On removal from the oven the silicon monoxide mesh is mounted on a quartz ring by potassiun silicate cement and heated in air to 500C. for 30 minutes to bake the cement. Such a screen 12, Fig. 5, may be mounted in front of luminescent screen 21. For writing the screens take up varying positive potentials the secondaries being collected by mesh 20 and on flooding the screen with low velocity electrons from second cathode 17 these electrons pass through the mesh 12 under control of the charge image to form a visible image on luminescent screen 21. Alternatively the luminescent screen may be replaced by a collector (output) electrode, the device functioning as a pick-up tube.

In the blocking off position of Fig. 3, the vanes fill the annular path between the jet pipe wall and an exhaust cone 20. Two of the ;bevel gears 36<SP>1</SP> are rotatable by hydraulic control units 44 to move the vanes to this position, and the pressure of the gas stream is relied on to return the vanes to the normal rearward exhaust position parallel to the jet pipe axis when pressure fluid is cut off from units 44. The apertures 46 in the jet pipe wall are in two diametrically opposed sets, each set having a shutter 50 sliding in guides 48 and provided with apertures 52. Springs 56 normally hold each shutter so that apertures 46 are closed, but admission of pressure fluid to a hydraulic unit 72, which may be hydraulically inter-connected with units 44, pulls on cables 59 anchored to the shutters at 60 to move the shutters and align apertures 46 and 52. When the hydraulic pressure is cut off, the shutters are returned by springs 56. Part annular shrouds 74 extending outwardly and forwardly direct the gases issuing from apertures 46.
