IPC: B64C39/00
Filed: 1929-09-20
Abstract: 339,382. Gilbert, W. V. Dec. 12, 1928, [Convention date]. Aeroplanes; fuselages; planes, construction of, and connecting together and to machine.-An aircraft wing A comprises a blank of metal such as steel or aluminium suitably curved or cambered to act as an aerofoil and having its inner end 1 curved or bent at an angle and indented or cambered in a reverse direction as at 2 and has means for rendering the aerofoil inert or immovable with respect to the lower end of the blank. Two wings A may be mounted to form an aeroplane, the parts 1 forming the sides of the body. The wings may be joined by a bridge piece 7 and the top of the body made from a dished cover plate 6, Fig. 14. If a gap occurs at the bottom a metal sheet 5, Fig. 13, may be riveted to the sides. Parts of the indented rib 2 may be cut away and covered by convex fairing plates. The wings may be formed with raised strengthening ribs and may be given an aerofoil section by curving their leading edges, Fig. 24, or by attaching separate curved portions. Each wing may consist of two bowed indented plates 10, 11, Fig. 17, having interposed spacing members 12, Fig. 18, and may be made watertight. The upper plates on each side may, alternatively, be formed integrally with one another extending across the body and having an upwardly curved mid portion. The internal reinforcement of the: wing may be of metal strips arranged honeycomb fashion or a girder such as 13 may be used. The blank from which the wings is formed may be composed of several metal sheets riveted or welded together. The various parts, of the aircraft are united by bolts and nuts to facilitate erection and disassembly. Tanks, arrangement and disposition of. - The nose of the aeroplane, may be fitted with bowed plates forming a watertight compartment in conjunction with the adjacent parts of the body or wings to form a tank or tanks of saddle or kidney shape to carry petrol or to provide buoyancy.

Patent GB-259407-A (GB)
Title: Improvements in the manufacture and production of iron carbonyl
IPC: C01G49/16
Filed: 1925-11-13
Abstract: 259,407. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Nov. 13, 1925. Iron carbonyl is produced in different appaxatus from that in which the metallic iron used as the raw-material is prepared and to ensure that fresh metallic surfaces are presented to the carbon monoxide the iron is again reduced in the reaction vessel or steps are taken to prevent oxidation of the iron as it is transferred to the reaction vessel. In an example Swedish iron sponge is broken up in an inert atmosphere, such as carbon dioxide in a roller mill and is transferred to a high pressure furnace without being brought into contact with air. Carbon monoxide is introduced at once or after the iron has been again reduced with hydrogen or purified water gas under pressure. Pure commercial iron powder is used in a second example and before passage of the carbon monoxide it is reduced with hydrogen. In a third example ground siderite is reduced with hydrogen in a revolving furnace and is then passed to a receptacle containing an inert gas, such as nitrogen from which it is withdrawn to the reaction vessel with exclusion of air. To avoid oxidation of the iron during the reaction the carbon monoxide employed may be freed from oxygen and carbon dioxide by passing it over heated copper !and soda-lime or alkaline sodium hydrosulphite and the temperature of the reaction must not be allowed to rise sufficiently high for the carbon monoxide to be decomposed to carbon dioxide and carbon. This latter reaction must also be avoided if carbon monoxide is used for reducing the iron. It is stated that the iron may contain nickel, aluminium or bismuth or compounds thereof, as they act catalytically and also, in some cases prevent the breaking up of the iron sponge to powder. This is prevented also by an addition of water glass or aluminium nitrate.
Patent GB-812557-A (GB)
Title: Improvements in or relating to gas turbine power plants
Inventor: FAUGHT HAROLD FRANKLIN
IPC: F02K1/16
Filed: 1955-10-10
Abstract: 812,557. Gas turbine jet propulsion plant. WESTINGHOUSE ELECTRIC INTERNATIONA.L CO. Oct. 10, W55, No. 28751/55. Class 110 (3). A gas turbine power plant fuel control comprises a speed governor for controlling the supply of fuel to the combustion chamber and a mechanism responsive to the pressure downstream of the compressor inlet for modifying the setting of the speed governor to limit the ratio of N/#T to a maximum value where N is the angular velocity of the power plant and T the absolute temperature at any point in the power plant upstream of the turbine inlet. The fuel supply to main combustion apparatus 22 is controlled by a speed governor 32 the controlled speed of which is set by a throttle or power lever 38 acting through a cam on an adjusting member 40. Electrical automatic temperature control apparatus 41 is used to control an actuator 31 which varies the area of the exhaust nozzle 15 in accordance with temperature conditions in the engine and the position of the power lever 38 by eyelid members 28a, 28b. The temperature control apparatus 41 has a temperature reference voltage unit 42 connected to a manual temperature scheduling potentiometer 43 and a control amplifier unit 46 connected to a thermocouple 47 disposed in the turbine exhaust. The contact member 50 of the potentiometer 43 is actuated by the power lever 38 and is electrically connected to one end of the temperature setting potentiometer 51. With the above arrangement, the area of the exhaust nozzle 15 is varied in accordance with the position of the power lever 38 to maintain a desired temperature in the engine for each position. of the power lever. To limit the stresses in the power plant the speed governor is modified to limit the ratio N/#T to a maximum value just below that at which the stresses reach their allowable limits. For this purpose a control unit 60 is provided. The control unit is responsive to the pressure difference between a pressure in the compressor obtained from a probe 63 and ambient pressure admitted to the housing 61 through an aperture 82. A rod 66 operated by the control unit 60 in response to this pressure difference rotates a shaft 67 which modifies the setting of the speed governor 32 to a lower value and at the same time varies the setting of the potentiometer 51 to reduce the temperature setting of the reference voltage unit 42. The control unit 60 also operates when fuel is injected through the spray pipe 24 into the turbine exhaust. To prevent further adjustment of the temperature scheduling potentiometer 43 in this range, a portion 43a having zero resistance is provided. The probe 63 may be disposed anywhere in the compressor between its inlet and outlet and the aperture 82 may be connected to a point upstream of the probe 63 and need not necessarily communicate with the ambient air. The thermocouple 47 may be disposed upstream of the location illustrated.
