Title: Improvements relating to generating video signals
Inventor: ASTLEY EDWARD THOMAS
IPC: H04N5/228
Filed: 1968-06-18
Abstract: 1,235,201. Image pick-up tubes. CROSFIELD ELECTRONICS Ltd. 22 July, 1969 [18 June, 1968], No. 29063/68. Heading HID. [Also in Division H4] The remnant image on the target of an image orthieon pick-up tube is removed by flooding the photo-cathode with light at the end of the scanning of the target and simultaneously adjusting the potentials of the photo-cathode and the accelerator electrodes relative to the potential of the target such that the energy level of the photo-electrons produced by the flooding light is insufficient to cause secondary emission from the target but sufficient to neutralize positive charges (remnant images) remaining on the target. The invention is of particular advantage when the input scene changes rapidly from one frame to the next, or changes completely, as in the case of flash photography and the embodiment described is concerned with the latter type of operation. As shown in Fig. 1 (the pulse waveforms of which are also shown in Fig. 2) a pulse A triggers a flash tube 6 to form an image of an object 4 on the photo-cathode 10 of an image orthieon 8, a pulse B derived from A triggering a bistable 29 to initiate the commencement of the frame scanning ramp generator 26 the forward stroke of which is terminated at a predetermined level V by means of a sensing circuit 28. (The line scan is effected by a line ramp generator 25 which may be synchronized with the frame scan if desired). The C pulse output of bi-stable 24, which triggers ramp generator 26, is also utilized via a differentiating circuit 30, a monostable circuit 34 and a second differentiating circuit 38 to initiate via bi-stable circuit 42 the production of a pulse N the leading edge of which occurs with a delay, relative to the commencement of the frame scan ramp, determined by the period of the monostable circuit 34 (pulse I). Pulse N then operates via amplifiers 46, 48 to modify the potentials of the photocathode 10 and the accelerator electrode 14 as described above and this condition is maintained until bi-stable 42 is reset by a pulse M derived from the D pulse output of bi-stable 24 via differentiating circuits 32 monostable circuit 36 and a further differentiating circuit 40. Coincidently with the production by monostable circuit 36 of pulse J (the trailing edge of which initiates pulse M) a pulse P is derived and this is employed to trigger a circuit 50 controlling a flash tube 57 which provides the flooding light beam for the photo-cathode 10. To ensure that the bi-stable circuit 42 is in the correct stage before the first image is flashed on to the tube clock pulses R are fed to an AND gate 54 from which they pass via OR gate-44 to reset bi-stable 42 only when the (negatively going) pulse P is not present.

Title: Improvements in or relating to aircraft with rotative wings
IPC: B64C27/02
Filed: 1925-11-25
Abstract: 264,968. La Cierva, J. de. Nov. 25, 1925. Screw and like propellers.-In aircraft embodying a freely-rotative wing-system of the kind described in Specification 196,594, means are provided for folding the wings so that they may lie relatively close to the fuselage. As shown in Fig. 2, when it is required to house or transport the machine, the wings A are swung upwardly about their horizontal root hinges. The shaft C on which the wing-supporting member B rotates, is mounted in horizontal bearings D, Fig. 3, so that after the wings A have been brought to the position shown in Fig. 2, the system may be swung rearwardly to lie above the fuselage. In its normal upright position, the lower end of the shaft C is held in a bracket E by a retaining member G. Where the wings are pivoted to have freedom of movement in the plane of rotation, as described in Specification 264,963, the flexible bracings are removed and the laterally extending wings are swung close to the fuselage. Fig. 5 shows an arrangement, in which two wings A are horizontally rigid and the other two wings A<1> mounted on secondary vertical pivots to permit them to be folded rearwardly. According to the Provisional Specification, a suitable arrangement for swinging the wings upwardly consists in attaching the bracing members, which serve to prevent the wings from falling below a certain level, to a movable member adapted to slide within the shaft C.

Title: Improvements in and relating to carburettors and like vaporizing devices for internal combustion engines
IPC: F02M9/10
Filed: 1922-11-01
Abstract: 210,521. Walter, C. M. Nov. 1, 1922. Fluids, regulating volume of flow or pressure of. -The air inlet to a carburettor, the passage around the nozzle or the mixture outlet may be varied by providing within the rigid carburettor passage a flexible surface or membrane of rubber or other expansible material to which fluid pressure may be applied externally and uniformly around its periphery to cause it to extend towards the axis of the passage whilst preserving a bore of substantially Venturi form. The casing b has a gauze-covered air inlet g and an outlet c controlled by a throttle valve l. The passage around the nozzle d is varied by applying liquid or gaseous pressure to the exterior of the membrane l formed in one with a cylindrical part j secured in a recessed part of the casing b by undercut ends h and spring rings k. The membrane l is of decreased thickness towards the centre in order that it may expand more at that part. The fluid is admitted by a pipe o and a short tube m a head p on which may be drawn against the rubber j by a nut q, or the tube may be vulcanized into the rubber before the latter is inserted in the carburettor. The fuel nozzle d may lie along the axis of the tube or be at right-angles thereto. The tube o may lead to an elastic fluid reservoir enclosed within a cylinder, a piston in which may be moved by a coarse-pitch screw rotated by hand through a Bowden cable, or automatically in accordance with engine speed. When actuated by hand, a scale may be provided to indicate the minimum bore and bores for ordinary running. The piston may be connected to a centrifugal governor driven by the engine. The membrane may also be actuated by the pressure of the lubricating oil which may act directly upon the piston referred to above, or upon the elastic fluid reservoir through linkages. According to the Provisional Specification, the membrane may be actuated (1) by glycerine or other fluid to which pressure may be applied by a piston, (2) by a diaphragm of substantial area exposed to the atmosphere on one side and (3) by an iris diaphragm encircling the membrane at its centre, or by a series of laminae normally parallel to the axis of the tube and attached at one end to a ring which may be rotated.

Abstract: 818,444. Pipe connections. UNITED STATES RUBBER CO. Sept. 27, 1957 [Nov. 9, 1956], No. 30347/57. Class 99(1). [Also in Groups XIX and XXXVII] Apparatus for inflating and deflating an article 16a is combined with a counter 52 for counting the number of articles inflated by providing a coupling having a chamber 19, which, during inflation of an article 16a having a fitting 16 through which fluid can flow into and out of the article, is closed off from the outer atmosphere and communicates with the fitting and also with fluid responsive bellows 39 for causing actuation of the counter 52. To inflate an inner tube 16a placed in a curing mould 15 with its valve stem 16 in a conical bore 17a and the threaded end 53 in engagement with sealing material 18, fluid under pressure is introduced through ducts 27, 30 causing a plunger 20 to move to the right so that a ring 35 seals the chamber 19 from communication with atmosphere through ducts 25 and compressing the material 18 into fluid tight engagement with the stem 16. Fluid in the chamber 19 flows through the valve stem 16 to inflate the inner tube 16a and when the pressure builds up sufficiently in the bellows 39 to overcome the spring 43, a mercury switch 48 is tilted to the position shown to make a contact in a circuit for actuating the counter 52. To deflate the tube the fluid pressure to the ducts 27, 30 is cut off and fluid escapes to atmosphere from ducts 25 and is prevented from introducing impurities into the ducts 27, 30 by a one way valve 33 and by a sealing ring 24 on the plunger 20.
