Title: Improvements in or relating to electronic discharge storage tubes
IPC: H01J31/64
Filed: 1963-05-22
Abstract: 987,522. Cathode-ray storage tubes. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 22, 1963 [June 7, 1962], No. 20346/63. Heading H1D. A cathode-ray storage tube comprises a storage grid on which a first charge pattern representative of an image is produced, a flooding electron source, a storage target exhibiting the property of bombardmentinduced-conductivity and positioned to receive flood electrons which have passed through the storage grid, and a reading electron gun for scanning the second charge pattern produced on the target to derive an electric output signal. The tube shown in Fig. 1 comprises a flooding gun 10-12, a writing gun 2-4, a storage grid 20 and a collector grid 19, similar to the corresponding elements of a direct-view charge-storage tube, the number of slow flooding electrons which are able to pass through storage grid 20 being determined in accordance with the positive charge pattern produced on grid 20 by fast writing electrons. The modulated flooding beam is then accelerated so as to produce a conductivity pattern in a target 22, comprising a metal mesh supporting a metal film and a BIC layer of zinc sulphide, the free surface of which is initially stabilized at a positive potential by scanning with the reading beam from gun 36. Further scanning with the reading beam produces an output signal at collector 28 and/or target 22. Since signals are stored both at grid 20 and at target 22, a first signal may be erased only at grid 20 and further signals may be superimposed on the first at target 22. In an alternative arrangement, the writing gun is replaced by a photocathode 49, Fig. 5, irradiated with a visible or invisible light image or with X-rays or #-rays, an annular flooding gun 59 being used.

Title: Method of and means for identifying defective apparatus
IPC: H04B17/40
Filed: 1945-08-08
Abstract: 619,217. Repeating systems. COMPAGNIE GENERALE D'ELECTRICITE. Aug. 8, 1945, No. 20371. Convention date, Dec. 4, 1944. [Class 40 (iv)] [Also in Groups XXXVI and XL (c)] To locate a fault in series-connected amplifiers, each is in parallel with a tuned circuit, and by reversal of line current the amplifiers oscillate so that when a fault occurs in one of the amplifiers it fails to oscillate and can be located by examining the characteristics of the group as a whole. The amplifiers comprise valves 1, 2, 3 whose filaments are heated by line current and whose anode and grid potentials are also supplied by line current over rectifiers C1 ... C4, so that the amplifier operates irrespective of the direction of current in the line. Each amplifier is bridged by a characteristically tuned circuit R, L and a uni-directional conductor D, so that when the current in the line is reversed, the amplifiers oscillate. If one amplifier is faulty, not only does it fail to oscillate, but it breaks the chain, so that the line delivers only those frequencies developed by the amplifiers to one side of the faulty amplifier, and an analysis of the line output enables the location of the faulty amplifier to be determined.

Filed: 1972-05-03
Abstract: 1348223 Fluid-pressure servomotor systems H J SHAFER 3 May 1972 [15 Oct 1971] 20601/72 Heading G3P A main valve 10 in a pipeline 11, 12 is closed in response to a predetermined pressure drop by an element 41 connected across an orifice 51 through which fluid escapes from a storage tank 53 to the low pressure section 12 of the pipeline after the pressure drop has operated shuttle valves 22, 23. The element is displaced against a spring loaded detent 63 to operate a lever 32 and a valve 28 to connect the high pressure section 11 of the pipeline and a storage tank A to a line 30 to force oil from a cylinder 35 into a rotary motor 13 to close the valve 10. Oil expelled from the motor is collected in a cylinder 35' connected to an exhaust line 31' through a valve 28' and a line 30' . To re-open the valve 10, the valve 28' is actuated by the lever 32. The element 41 may be a piston or a diaphragm with shafts 45, 46 of different diameters to make the sensitivity of the control independent of changes in pipeline pressure. In a second embodiment, the valve 10 is automatically reopened if the pressure drop has not been sufficiently great to justify closure. Fluid from the section 12 flows through a throttle (73) Fig.2 (not shown) into a storage vessel (73) and eventually opens a fluid loaded relief valve (75) to operate a piston (80) connected to the lever 32. A trigger valve (70) operated by the motor 13 isolates this part of the system when the valve 10 is open. In a further embodiment, the orifice 51 is replaced by a valve (186) Fig.4 (not shown) operated by a timing relay (175) of known construction. A hand pump 40 allows the valve 10 to be operated manually.
