Title: Improvements in or relating to cathode ray tubes or the like
IPC: H01J31/12
Filed: 1951-01-04
Abstract: 680,402. Cathode ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Jan 4,1951 [Jan. 4, 1950], No. 316/51. Class 39(i) A cathode ray storage tube comprises a fluorescent screen, a foraminated control electrode positioned in close proximity to the fluorescent screen, means producing a virtual cathode adjacent to the control electrode, scanning means producing a charge pattern on the control electrode which controls the transference of electrons from the virtual cathode to the fluorescent screen and means for erasing the charge pattern. The foraminated control electrode may be a metallic mesh covered with a thin insulating film 1-2 microns thick. In Fig. 2 the fluorescent layer F is covered with a layer of aluminium 2 which is connected via metal layer 3 to an external electrode 4 at 10,000 volts. The mesh G is located a few millimetres from the screen F, and is given a potential of 1000 volts. An accelerator mesh 6 at 2000 volts is provided one millimetre from mesh G on the gun side, and is connected to a graphite layer 8 on the tube wall. There are three electron guns S, M, E. Gun S which is at 1000 volts, is spherical and concave and produces a wide flooding beam, the electrons from which are retarded between grids 6 and G to form a virtual cathode, Gun M at earth potential is modulated by the video signal and scans the mesh G, the secondary emission of the insulating layer producing a potential pattern on the grid. The gun E is at 10,000 volts negative and scans just in advance of gun M to erase the previous pattern. The gun E may be omitted and the layer on the mesh G must then have such slight conductivity as to allow discharge during the complete image period. Alternatively the material of the insulating layer may be photo-conductive and erasure obtained by uniform illumination of the control grid through a window in the side of the tube. The tube is applicable for producing television, radar or oscillograph images. The trace of the latter may persist for several seconds to allow visual observation or photographic recording. The fluorescent screen may be of layers, which produces ultra-violet radiation. The fluorescent layer may be cooled by a current of cold water. In large screen projection using a Schmidt optical system the shape of the fluorescent screen conforms with a portion of the surface of a sphere and the meshes G and 6 are concentric therewith. The modulation of the controlling beam may be obtained by the occulting action of a small aperture across which the beam is deflected.

Filed: 1954-01-08
Abstract: 757,416. Polarizing apparatus. AMERICAN OPTICAL CO. Jan. 8, 1954, No. 636/54. Class 97 (1). On viewing a stereoscopic pair of lightpolarizing images A, B through polarizing analyzers C, D, the ghost of the image intended for one eye, which is visible to the other, is made invisible by adjusting the density of the background so that the ghosts blend with the background and become substantially indiscernible. Preferably, the images are viewed by polarized light and the density of the background is varied by inclining the axes of the analyzers towards or away from one another. The polarized light may be provided by a polarizing layer 21 which may be attached to the image layers 20. The polarizing axis of the layer 21 may be vertical in which case the axes of the analyzers C, D are each displaced, through the angle between the arrows into the position of the dotted arrow. If the polarizing axis of the layer 21 is horizontal, the analyzers C, D are rotated in the opposite sense. Instead of rotating the analyzers, the polarizing axes of the image portions A, B may be rotated relatively to the layer 21. The image portions A, B may be projected by plane polarized light on to a non-depolarizing screen and the projected image viewed as is the picture in Fig. 3. Specifications 556,578 and 562,877 are referred to.
