Abstract: 1460758 Vapour deposition PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 April 1974 [27 April 1973] 17889/74 Heading C1A Deposits, e.g. gallium arsenide phosphide or mono or polycrystalline semi-conductor materials, are formed on substrates by placement in a zone of a tubular furnace and passing a gaseous mixture of the elements to be deposited, whose temperature is higher than that of the zone, along the track of the substrates disposed along the direction of flow of the gas mixture; the major surfaces of the substrates are inclined or perpendicular to the direction of the gas-flow and the successive distances between adjacent substrates increase from the first substrate reached by the gas to that present nearest to the point of removal of the gas flow. The gas mixture diffuses into the spaces between the substrates and becomes depleted with respect to the elements along the path of the gas flow in the zone. Increases in spacing between substrates compensates for depletion and the deposition rates at the substrates reach an equilibrium and thicknesses of the deposits at each substrate are substantially the same.

Title: Improvements in the manufacture of hydroxy aliphatic amines
IPC: C07C215/08
Filed: 1930-06-16
Abstract: Hydroxyaliphatic amines are manufactured by hydrogenation of cyanhydrins (a - or b -oxyaliphatic nitriles) in the presence of hydrogenation catalysts such as nickel, copper, platinum, palladium, cobalt, and iron.  The hydrogenation may be carried out at atmospheric or raised pressure, using pure hydrogen or gases containing hydrogen with or without carbon monoxide, e.g. water gas, town gas, or producer gas, in the liquid phase with or without a diluent, in an acid medium or in the vapour phase.  In an example, ethanolamine is prepared by treating glycollic acid nitrile in aqueous solution with hydrogen or gases containing it at 10-20 atmospheres in the presence of palladium chlorides and gum arabic.ALSO:Hydroxyaliphatic amines are manufactured by reduction of cyanhydrins (a - or b -oxyaliphatic nitriles) by any suitable method, e.g. by means of zinc and dilute sulphuric acid or sodium or sodium amalgam and alcohol, but preferably by catalytic hydrogenation, nickel, copper, platinum, palladium, cobalt, and iron being specified as catalysts.  The hydrogenation may be carried out at atmospheric or raised pressure, using pure hydrogen or gases containing hydrogen with or without carbon monoxide, e.g. water gas, town gas or producer gas, in the liquid phase with or without a diluent, in an acid medium or in the vapour phase.  The cyanhydrins may be prepared, advantageously in situ, by the action of hydrocyanic acid on aliphatic aldehydes or ketones or on alkylene oxides, preferably in the presence of caustic alkali, potassium or sodium carbonate or other alkalies or potassium or sodium cyanide, or by the action of an alkali cyanide in conjunction with sufficient acid to liberate most of the hydrocyanic acid.  The products may be converted into useful derivatives by esterifying the hydroxy group or alkylating, aralkylating or acylating the amino group, or may be used in making oxyalkylamino derivatives of organic compounds, especially dyestuffs, e.g. in preparing oxyalkylaminoanthraquinones by the action of a hydroxyaliphatic amine on an anthraquinone derivative containing a negative substituent, e.g. a nitro group or a halogen, or on a leuco oxyanthraquinone followed by oxidation.  In an example, formaldehyde solution is treated with potassium cyanide and hydrochloric acid and the glycollic acid nitrile produced is treated with hydrogen or gases containing it at 10-30 atmospheres in the presence of palladium chloride in aqueous solution containing gum arabic, producing ethanolamine.  Other cyanhydrins specified are: lactic acid nitrile (obtained from acetaldehyde), a -oxybutyric acid nitrile (from propionaldehyde), tartaric acid dinitrile (from glyoxal) and hydracrylic acid nitrile (from ethylene oxide).

Abstract: 741,336. Gas turbine plant. ARMSTRONG SIDDELEY MOTORS, Ltd. June 1, 1954 [July 3, 1953], No. 18445/53. Class 110(3) To prevent icing, hot gaseous fluid is fed to an annular internal chamber provided at the base of the air intake webs or spokes of the axial flow compressor of a gas turbine plant and is delivered in parallel therefrom to the inner surfaces of the for ward edges of all the spokes, to the interiors of all the intake guider vanes, and to the interior surface of the nose fairing of the intake. In. the arrangement shown six spokes 11 support an internal intake casing 23 from the external casing 17. Hot gas from a conduit 20 passes through a passage 21 formed along the rear portion of one or more of the spokes to an annular internal chamber 22 within the casing 23. The hot gas may be the air from the discharge of the compressor of a compound engine, or may be air from the compressor which has been heated. The conduit 20 is connected to the casing 17 by a casing 26 which has an opening 27 to receive an extension 28 for heating the lip of the intake duct (not shown). The opening 27 may be blanked off. Tubes 31, located in each of the spokes, communicate with the chamber 22 and have perforations 32 which direct the hot gaseous fluid against the adjacent front walls 18 of the spokes. Baffles 33 are arranged to box in the forward portion of the spokes. The hot gases pass from the interior of the spokes into the air stream through livTes 34, 37, 38. The supports 31a of the tubes 31 provide gaps 39 adjacent the edge 18 to prevent cold spots in these areas. The chamber 22 supplies hot gas to the guide vanes 40. Each vane 40 comprises an outer shell 41, an inner control baffle or tube 42 and attachments 43, 44 brazed to both ends of the vane. The hot gas flows from the tube 42 through slots 46 over the inner surface of each outer shell 41 and then passes through small gaps 48, 49 into the airstream. A modification in which the vanes 40 are adjustable is described. Hot gas is also led from the chamber 22 by means of three pipes 51 to a chamber 53 from which it flows along an inner annular space 54 to the holes 55 and thence into the airstream.

Filed: 1962-05-14
Abstract: 940,759. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 14, 1962 [May 27, 1961], No. 18498/62. Heading G6C. A device for preventing fuel elements from moving back once they have been inserted into a nuclear reactor fuel channel comprises resilient arms bent towards the axis of the channel and integral with a member which abuts axially against the wall of the channel. As shown in Fig. 2, a metal sheet having punched-out arms 5 is rolled up to form a thimble 6 and inserted in a counterbore 7 in the channel 1. When a fuel element 3 is inserted, the arms 5 are opened out to allow the element to pass whereupon they return to their initial position with their tips 9 bearing against the end of the element. Holes 19 in the thimble 6 enable it to be gripped by pincers to effect contraction during its insertion. An alternative form of thimble 6, shown in Fig. 9, has the arms 5 extending to the forward edge of the thimble. The thimble is prevented in this case from sliding forward along with the fuel element 3 by means of openings 11 which engage tongues carried by the channel wall. Alternatively, some of the arms 5 may extend outwardly to engage the forward end of the counterbore 7, or small punched-out strips in the walls of the thimble may abut against shoulders in the counterbore 7. Operation of the device is facilitated by using fuel elements the front ends of which have truncated bullet-noses 24 and the rear ends of which have stepped portions 22 providing shoulders 23 against which the tips 9 of the arms 5 abut.
