Title: Oil cooling arrangement for gas turbine aircraft engines and operation thereof
Inventor: STRETTON RICHARD GEOFFREY
IPC: F02C7/141
Filed: 2009-09-21
Abstract: An aircraft propulsion arrangement including a gas turbine aircraft engine 1 having a compressor 9, an oil system configured to route engine oil through a heat exchanger 19 mounted so as to define part of an aerodynamic surface to the flow of ambient air, and a duct arrangement 13 fluidly connecting the compressor to the heat exchanger. The compressor is provided with a bleed takeoff 12 configured to bleed gas from the compressor wherein said bleed gas is directed by said duct arrangement to flow across the heat exchanger in a heat exchange relationship with said oil. A flow controller 13a is provided actuable to selectively regulate the flow of compressor gas across the heat exchanger. The aerodynamic surface is provided by a pylon 2 and incorporates said heat exchanger. The flow of compressor gas across the heat exchanger may be controlled selectively in dependence on one of; the temperature of engine oil measured within the engine, the airspeed of the aircraft and the aircraft flight cycle conditions.

Title: Encapsulated electrical apparatus
Inventor: LINK EDWIN A
IPC: H01B3/00
Filed: 1970-03-03
Abstract: 1298982 Transformers RTE CORP 3 March 1970 10150/70 Heading HIT A porous electrical device such as a transformer core and coil assembly is impregnated with a dielectric material and coated with a flexible resin (or lead) to retain the dielectric material which has the property of being liquid and drop forming when subjected to heat during impregnation and is subsequently made non-drop forming by being cured or cooled during or prior to encapsulation. The dielectric material is fluid at working temperatures above 0‹ C. Encapsulation may be effected by a hot fluidized bed of resin by spraying or by dipping into molten lead. Alternatively a polyester glass laminate may be built-up. The dielectric material may be thixotropic (isopropylenes, polyphenyls, polyphenylethers treated with a jelling agent, hydrocarbons, ethers, halogenated hydrocarbons) a monomer which is polymerized into a permanent fluid jelly state after impregnation or a liquid which becomes solid at - 10‹ C. or lower or becomes wax-like down to - 40‹ C. (hydrocarbons, ethers, silicones &c). In the latter case the impregnated device is cooled before encapsulation.

Abstract: 430,375. Filters. WELLS, M. T., 42, Sparhawk Street, Amesbury, GOLDMAN, J. H., and GOLDMAN, J., 14, Somerset Street, Boston, both in Massachusetts, U.S.A. April 4, 1934, No. 10192. [Class 46] A pad or block for filtering milk or other liquids is formed of a succession of webs or layers of carded fibres, for example of cotton, jute, wool or silk, with perforated spacing sheets of impermeable material separating adjacent webs, the perforations of the several spacing sheets being arranged in alignment. The spacing sheets may be of metal, plastic material, paperboard or cellulose pulp, and the greatest dimension of the perforations is less than the staple length of the fibre. To facilitate handling the webs may be reinforced or backed with paper having perforations corresponding to those in the spacing plates, the web and backing being held together by adhesive. Each web may be of multi-ply structure, the fibres of one ply being at an angle to those of the adjacent ply. As shown the filter block 11 is clamped between a ribbed and grooved base plate 160 and a similar top plate 170 by means of a nut with handle 26 screwing on a central post 23. The grooves on the base and top plate correspond to circular series of perforations in the spacing plates. The apertures 130 in the lowest impermeable sheet may be smaller than those in the sheets above. As shown the liquid passes from an inlet 20 to the grooves in the top plate and the filtrate collected in the grooves of the base plate passes to an outlet 22, but filtration may be in the reverse direction.

Title: A process for effecting the catalytic dehydrogenation of hydrocarbons
IPC: C07C5/32
Filed: 1936-04-16
Abstract: For the dehydrogenation of hydrocarbons a catalyst consisting principally of oxides of aluminium and chromium is used at a temperature of 500--700 DEG  C.  The catalyst may contain 6--40 per cent of chromium oxide, and is preferably made by impregnating porous calcined alumina with chromic acid solution and subsequently reducing to chromic oxide by treatment with the reaction gas.  It may be reactivated when necessary by oxidation at 400--700 DEG  C.  The dehydrogenation process is particularly applicable to paraffin hydrocarbons, but may also be applied to hydroaromatic and other hydrocarbons capable of further dehydrogenation without cracking.  It may be effected in presence of diluents including hydrogen, or of a hydrogen acceptor such as ethylene.  Moderately reduced or increased processes may be employed.  Examples describe the dehydrogenation of propane, butane, isobutane, cyclohexane, and ethylbenzene. Specifications 293,887, 293,906, [both in Class 1 (i)], and 423,885 are referred to.
