Title: Gas turbine engines
IPC: F02K1/09
Filed: 1972-05-09
Abstract: 1418905 Jet propulsion nozzles - variable area ROLLS-ROYCE (1971) Ltd 7 May 1973 [9 May 1972] 21659/72 Heading F1J The invention relates to a propulsion nozzle for a gas turbine engine which comprises a cowl which defines the nozzle area and which includes a fixed portion and a portion movable axially in relation to the fixed portion to form an opening thereby defining additional nozzle area. The engine shown in Fig. 1 is a gas turbine ducted fan engine comprising a fan 15 disposed within a cowl 14 which defines with the core engine 17 a fan duct 18. The pitch of the fan blades is variable and the pitch may be reversed so as to provide reversed thrust. The cowl comprises a fixed forward part 24 and an axially movable rearward part 20, the latter being movable by an assembly of four screw jacks 31 and guided by means of a rail 19. The movable part 20 may be disposed in a first position Fig. 2 in which it abuts the fixed portion 24 so that the fan air flows straight through the duct, this being the position in cruise flight; or in a second position Fig. 3 in which it is spaced axially downstream of the fixed portion so as to define an annular opening 40 so that the fan air passes both axially through the duct and through the opening 40 as indicated by the flow arrows 41 and 42; or in a third position Fig. 4 in which it is spaced further downstream, this being the position during reverse thrust operation, air flowing in through the annular opening as indicated by flow arrows 43. The surface of the cowl parts are shaped as at 34 to promote attachment of the air-flow to the surfaces of the cowl. In a further embodiment the cowl comprises two axially movable parts, the fixed part and the two movable parts being disposed in abutting relation for cruise flight, the downstream movable part being moved axially so as to define an annular opening and thus an increased nozzle area for aircraft take-off, the intermediate part being movable axially downstream so as to abut the downstream movable part thus providing an annular opening of increased area for reverse thrust operation.

Abstract: 285,417. Pharmagans Pharmaceutisches Institut L. W. Gans Akt.- Ges. Feb. 16, 1927, [Convention date]. Drawings to Specification. Medicines for internal use; bacteria, cultivating.-Lipoids, particularly phosphatides, are extracted from materials containing them by dialysis without destruction of the cellular structure. The materials, e.g. peas and beans, are treated at a temperature not exceeding 37‹ C. with suitable liquids, e.g. water or dilute alcohol. The phosphatides are removed from the dialysing liquid by adding thereto fat-dissolving substances such as alcohol or acetone which cause precipitation of the phosphatide. Albuminous substances or products of their decomposition such as amino acids, aspartic acid, glutamic acid, &c. may be added. The phosphatides so obtained are stated to be soluble in water and may be dried and preserved in dry condition. Separation from the dialysing liquid mav also be effected by treatment with adsorptive agents such as aluminium and iron hydroxides, animal charcoal, &c. The phosphatides may be subsequently removed from these agents by the use of weak acids or bases or salt solutions- The phosphatides so obtained contain carbohydrates, anthocyanins, and inorganic compounds, in particular of calcium and iron, and are suitable for use as food, as medicinal substances or nutrient media for bacteria.

Abstract: 205,618. Merryweather & Sons, Ltd., Osborne, J. H., and Bown, C. H. Aug. 14, 1922. Extincteurs; sprinklers, automatic.-In a fireextinguishing apparatus in connection with sprinklers the fall of water in a tank owing to the opening of a sprinkler allows a float connected to an arm 2 to descend, transmitting pressure by a plunger and liquid in a cylinder F, to a Bourdon tube J causing it to uncoil slightly and release a lip N on the acid vessel. The gas pressure thus generated is used for driving out fireextinguishing liquid through the sprinklers or to drive two liquids from separate vessels to form foam, in the pipes or at the sprinklers. The float tank may be sealed or have a non-return valve to withstand the pressure of the fireextinguishing apparatus, or the float tank may be connected to a separate sprinkler pipe.
