Title: Aircraft having a spin indicator system
Inventor: HOSKINS DAVID VINCENT WILSON
IPC: B64D45/00
Filed: 1964-05-07
Abstract: 1,108,391. Aircraft spin indicators. ELLIOTT BROS. (LONDON) Ltd. 7 May, 1965 [7 May, 1964], No. 19103/64. Heading B7W. [Also in Division G1] Apparatus for indicating whether or not an aircraft is in a spin comprises two gyroscopes for measuring the rates and senses of rotation of the aircraft about its yaw and roll axes, the gyroscopes being connected to individual indicating instruments arranged in a cluster so as to be easily readable by the pilot. Each gyroscope comprises a single axis rate gyro with a potentiometer pick-off. In the described embodiment, a relay is connected in the yaw rate gyro pick-off circuit, the relay being arranged to block the indicating instrument connected to the roll rate gyro until a predetermined rate of rotation about the yaw axis exists. Alternatively the yaw rate indication, indicated by the lower pointer 22, may be blocked by a relay in the roll rate gyro pick-off circuit or the blocking may be dispensed with. A further potentiometer pick-off is provided to sense the positions of the ailerons, this being connected to the upper indicator 22 in the same cluster of instruments as provided for the gyroscope indicators 26. A fail-safe arrangement may be incorporated, whereby the instrument pointers disappear from view in the case of a power failure, and a safety height switch may be connected in the power supply to the instruments to interrupt the supply when the minimum height at which recovery from a spin cannot be guaranteed has been reached.

Abstract: 138,391. Whitehead Torpedo Works, and Ridsdale, H. W. Dec. 6, 1918. Generating by direct contact of combustion products. -- Relates to the generation of motive fluids for torpedoes by combustion of a fuel in oxygen under pressure with the addition of water or other cooling medium to the combustion gases, and consists in generating the oxygen by the decomposition of an oyxgen-bearing salt under the influence of heat derived from the combustion of an ingredient of a mixture which is contained in a closed veseel, and of which the said salt forms the chief constituent. In the form shown, the oxygen generating mixture is contained in cylinders B and is ignited by igniters b<1> when the torpedo is launched. A suitable mixture contains potassium chlorate and other ingredients as described in Specification 1256/07, [Class 90, Non-metallic elements]. The oxygen generated passes into a chamber A<1> and thence through a relief valve a<3>, a starting-valve a<1>, and a pressurereducing valve A<4> to the combustion chamber (not shown), which is supplied with fuel and water in the usual way. The water is contained in a chamber A<2>. The gases may be purified from chlorine in known manner. The chamber A<1> is initially charged with conpressed air or oxygen to start the engine and work the igniters. Some of the mixed products of combustion may be cooled and filtered for use for auxiliary devices, such as the gyroscope, the servo-motor, and the lubricating feeds; or a separate bottle of compressed air may be provided for these purposes.

Abstract: 1432696 Low temperature catalytic steam cracking IMPERIAL CHEMICAL INDUSTRIES Ltd 18 April 1974 [30 April 1973] 20420/73 Heading C5E A feedstock comprising one or more hydrocarbons having a higher molecular weight than methane and a boiling point under 350 C. is reacted with steam at 200 to 650 C. using a catalyst produced by reducing a precursor composition comprising 25-90% by weight of nickel-oxide calculated as NiO, alumina, 0À1 to 10% by weight of an alkaline earth metal compound calculated as equivalent magnesium oxide, and 0À05 to 3À5% by weight of an alkali metal compound calculated as equivalent potassium oxide K 2 O, the nickel oxide and alumina having been brought together by coprecipitation of water-insoluble compounds of nickel and aluminium. The catalyst may be derived from a precursor into which the alkaline earth metal compound was introduced by coprecipitation with the nickel and aluminium compounds. Hydrocarbons may be reacted with steam in the substantial absence of hydrogen and the proportion of alkali metal compound in the catalyst is 0À25 to 0À75% by weight, or in the presence of hydrogen and the proportion of alkali metal compound in the catalyst is 1 to 2À5% by weight, the percentage being calculated as equivalent potassium oxide K 2 O. All the feedstock can be fed to all the steam at the entry to the catalyst bed or in stages such that the steam/feedstock ratio is not reached until after the last portion has been introduced. The space velocity is low enough to permit the methane forming reaction of hydrogen with carbon oxides or with feedstock to proceed near to equilibrium. The process can be carried out in the presence of hydrogen, carbonoxides or methane or mixtures thereof, derived from a separate reaction stage or recycled product gas. The product gas may contain 50 to 70% methane and may be subjected to one or more methanation stages, with or without steam and/ or carbon dioxide remova, to produce a substituted natural gas, or may be subjected to one or more steam reforming and/or partial oxidation to produce a hydrogen-containing gas suitable for use, after purification, in ammonia, methanol or hydrocarbon synthesis, hydrogenation or metal smelting.
