    • 778,675. Aircraft air brakes. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. July 15, 1955 [Nov. 19, 1954], No. 33511/54. Class 4. [Also in Group XXIX] An aircraft air brake includes a flap 15 hinged on each side of the aircraft body forward of the tail and carried by two hinge members 12, 13, Fig. 4, one, 12, having one end pivoted to the body and the other end pivoted to the flap at 14 substantially at its centre of pressure, the other member 13 being pivoted to the body and flap at points spaced from the pivots of the member 12, with means for moving the two flaps simultaneously, the hinge members being arranged so that the centre of pressure of each flap moves initially, radially and then substantially radially with slightly increasing deviation from the radial direction. In Fig. 4, the arrow N points to the nose. Each member 13 is one part of a bell crank lever 13, 19, pivoted on a bracket 18, the arm 19 being pivoted to the body of a hydraulic valve 28 the valve rod 27 of which is attached by a bell crank lever to a rod 25 pivoted to a lever 24 mounted on a rotatable shaft. Each valve 28 controls a jack 20 operating between a pivot 21 on the fuselage and the flap 15, so that rotation of shaft 24 causes actuation of the jacks 20 until the valve bodies 28 are moved to re-centre the valve rods 27. In Fig. 5, each flap 31 is pivoted on two members 32, 33, the former being pivoted to the fuselage on a bracket 34, and the latter mounted on a shaft 35. A control rod 44 operates the piston 41 of a valve 40 pivoted at 39 to one member 33, the valve controlling the operating jack 38. In this embodiment, the flap 31 and hinge member 32 together form a smooth fairing in the retracted position shown in full lines, see Fig. 8 (not shown).

    • 742,983. Television. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. Feb. 25, 1953 [Feb. 25, 1952], No. 4851/52. Drawings to Specification. Class. 40 (3). In an arrangement for reproducing images of instrument dials &c. at a remote point by employing light generated by a cathode-ray tube "flying-spot" " scanner " and reflected or transmitted by the dials &c. to produce corresponding vision signals in a photo-electric cell, the cell is chosen to have a maximum response characteristic in the spectral region of the light generated by the cathode-ray tube. When a number of instruments which cannot be placed together are concerned, groups of them can be scanned by individual " scanners " and photoelectric cells, the outputs of which are mixed and the scanning is so arranged that each group occupies a part only of the picture reproduced at the remote point. The instruments (e.g. instrument panel in the case of an aircraft) and the signal generating equipment should, preferably, be enclosed in a light-tight box but if visual observation of the instruments is also necessary they may be illuminated by visible light of a different wavelength to that generated by the " scanner " an optical filter passing only light of the latter wavelength being interposed in the optical path to the photo-electric cell. Signals conveying other information (e.g. for telemetry) may be combined with the vision signals. In the case of " aircraft to ground " systems the synchronizing signal equipment may be located on the ground and synchronizing signals transmitted to the aircraft to synchronize the operation thereof. The receiving equipment may include provision for recording the reproduced images by means of a cinematograph camera in addition to a direct viewing picture reproducing cathode-ray tube. Specification 432,225 is referred to.

    • 734,446. Hinges. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. Dec. 9, 1953 [March 20, 1953]. No. 7718/53. Class 65(2). [Also in Group XXXIII] A hinge for a movable flap on aircraft is combined with mechanism to cause angular movement of the flap about the hinge. Each hinge comprises a bracket 16 secured to the wing of the aircraft and formed with forks 17 to accommodate a bracket 18 built into the associated edge of the flap and a sleeve member 20, mounted on a shaft 37, is formed with straight splines 21 and helical splines 24. The forks 17 are slotted axially for the splines 21 and the bracket 18 is formed with suitable slots to co-operate with the splines 24 which have freedom of movement in recesses 25 formed in the forks 17. A number of such assemblies may be located along the edges of the wing and flap and connected together by articulated links for axial movement under the action of an hydraulic jack to effect angular movement of the flap. The brackets 16 and 18 have recesses for the surface plating of the wing and flap respectively and the angular movement of the flap may be limited either by the side faces of the splines 24 engaging the sides of the recesses 25 or a projection 30 on the bracket 18 may engage co-operating faces on the bracket 16.
