Title: Improvements in or relating to gas turbine power plants for aircraft
IPC: F02C7/047
Filed: 1944-12-08
Abstract: 592,091. Gas turbines. BRISTOL AEROPLANE CO., Ltd., OWNER, F. M., and MARCHANT, F. C. I. Dec. 8, 1944, No. 24616. [Class 110 (iii)] [Also in Group XXXIII] An aircraft gas turbine power plant has a single tubular intake duct which receives air from two sources, the air from one source entering in the general direction of the longitudinal axis of the duct and the air from the other source entering radially inwards around its peripheral edge. The air supply to the compressor 7 of a gas turbine power plant 5, Fig. 1, may be taken through the intake duct 11 from the opening 12 or from the aperture 17 in the upper trailing edge of the wing 6. The air from the aperture 17 is heated by passing over the engine which is enclosed in a shell 15. The source from which the compressor draws its air is controlled by the louvre-slats 18, a sleeve 19 on the intake-duct 11 and a grilled plate 20. The controls are interconnected and operated from the cockpit. When the louvre-slats 18 are fully open, the sleeve 19 closes the peripheral opening to the intake duct and the plate 20 closes the aperture 17. When the slats are fully closed, the sleeve 19 is withdrawn and hot air passes to the peripheral opening through the aperture 17. If desired, intermediate settings of the cockpit control may be arranged so as to allow part of the air supply to be taken by way of opening 12 and part by way of aperture 17. The control of the air supply may be used to prevent icing of the intake 12 at high altitudes, to maintain laminar flow over the wing or to prevent stones entering the intake at starting. When fuel tanks are installed in the wing, the shell 15 minimises the fire hazard as it forms a heat-insulating jacket for the exhaust pipe 10. If desired, the shell 15 may be dispensed with and the power plant mounted in a sealed compartment. Reference has been directed by the Comptroller to Specifications 579,657, [Group XXXIII], and 587,126.

Abstract: 1,229,835. Antibiotic megalomicin complex. SCHERICO Ltd. 23 May, 1968 [26 May, 1967; 21 Feb., 1968], No. 24648/68. Heading C2A. Antibiotic megalomicin complex, components A, B, C 1  and C 2  and megalomicin C complex are produced by cultivating a strain of micromonospora megalomicea e.g. M.megalomieea var. megalomicea NRRL 3274 or a mutant thereof or M.megalomicea var. nigra NRRL 3275 or a mutant thereof, in an aqueous nutrient medium under aerobic conditions. Megalomicin complex may be isolated from the whole broth by adjusting to pH 9À5, extracting with a waterimmiscible solvent such as ethyl acetate and concentrating the extract. The concentrated extract may be (A) extracted with 0À14 N.HCl or 0À1 N.H 2 SO 4 , the acid extracts adjusted to pH 8À5 to 9À0, re-extracted with ethyl acetate and taken to dryness, or (B) subjected to chromatography e.g. on Sephadex (TM) suspended in 95% aqueous ethanol, eluted with 95% aqueous ethanol, the active fractions combined, concentrated to dryness, dissolved in ethyl ether or acetone, added to petroleum ether, allowed to stand at -50 C., the mother liquor separated and evaporated to dryness. On chromatography on a silicic acid column and elution with chloroform/methanol (60-40), antibiotic components -C1 and -C2 are first recovered. The remaining active fractions are combined and further resolution achieved by Florisil (TM) column chromatography to yield antibiotic components A and B. The antibiotics are nitrogen bases forming salts with acids e.g. hydrochloric, sulphuric, phosphoric, stearic, propionic, tartaric and maleic acids. They also form esters e.g. acetates, propionates, cyclopropyl carboxylates, succinates and benzoates with acid anhydrides. Megalomicin-complex is soluble in ethyl acetate, methanol, ethanol and acetone. Megalomicin has the formula wherein R 1  and R 2  is H, acetyl or propionyl according to component. The above antibiotics, their salts and esters are broad-spectrum antibiotics and may be formulated into pharmaceutical preparations for administration to humans and animals. Examples are provided of capsules, oral suspensions, parenteral solutions and suspensions, topical creams and ointments. They may be used as general disinfectants.

Abstract: 1287548 Ammonium carbonate from waste gases FARBENFABRIKEN BAYER AG 19 April 1971 [28 March 1970] 24799/71 Heading C1A An ammonium carbonate solution with a concentration of from 15 to 20% by weight is recovered in a process for the purification of waste gases from the production of ammonium nitrite, wherein the waste gas which comprises carbon dioxide, ammonium nitrite and ammonium nitrate is washed with an aqueous ammonia solution and in the presence of the solution the gas is reacted with additional carbon dioxide in such a way that the end gas has an ammonia content of less than 0À1% by volume. Carbon dioxide may be supplied in the form of smoke gas from power stations. The purification of the waste gases and the production of the ammonium carbonate are best carried out in an absorption column and for optimum yields the reaction temperature should be 20‹ to 50‹ C. The aqueous ammonia used in the absorption towers preferably has a NH 3  concentration of 6 to 10% by weight. To prevent ammonia from escaping the quantity of water required to dilute the 30% by weight aqueous ammonia used as the starting material can be separately delivered to the head of the column at a temperature of from 0‹ to 10‹ C. Instead of water it is also possible to use a dilute solution of the end product namely dilute ammonium carbonate solution.
