Abstract: 1299811 Semi-conductor devices RCA CORPORATION 28 April 1871 [4 May 1970] 11810/71 Heading H1K An integrated circuit includes an I.G.F.E.T., the gate insulation of which is formed by heating the device in a wet oxidizing atmosphere containing a hydrogen halide. In the embodiment, two complementary I.G.F.E.T.s 18, 20 are produced with a bipolar transistor 22, the source and drain regions 36, 38 of I.G.F.E.T. 18 being diffused simultaneously with the base region 26 of the transistor, and the source and drain regions 48, 50 of I.G.F.E.T. 20 being formed simultaneously with the emitter 28 and collector contact 30 diffusions. The gate insulations 44, 56 are formed by heating the device to a temperature of 875‹ C. in an atmosphere of water vapour and gaseous hydrogen chloride derived by evaporation of an azeotropic mixture of water and hydrochloric acid. The halide reacts with the dopant impurities in the forming oxide layers, the impurities being derived from the semi-conductor body, to form volatile chlorides thereof. The body is then annealed in a non- oxidizing atmosphere at a temperature of between 900-1200‹ C., but preferably below 1000‹ C. The annealing atmosphere may be hydrogen, helium or forming gas. The elements of the integrated circuit may be isolated within an epitaxial layer 16 by diffused zones 35 of the opposite conductivity type.

Abstract: 865,544. Turbine stator blade assemblies. NAPIER & SON Ltd., D. April 8, 1959 [April 14, 1958], No. 11873/58. Class 110 (3). A turbine stator assembly comprises inner and outer support rings and a series of hollow stator blades mounted between the two rings, the inner and outer support rings being each formed with a series of circumferentially spaced slots through which the respective ends of the blades project, tangentially extending apertures being formed in the projecting ends of the blades and locking- wires being threaded through the apertures. Means are also provided for delivering cooling air to an annular cooling chamber surrounding the outer support ring, the cooling air then passing radially inwardly through the hollow blades and issuing into an annular space formed within the inner support ring. The invention is shown applied to gas turbine inlet nozzle structure which comprises a series of hollow sheet-metal guide-blades 14 mounted between outer and inner rings 11, 12, the outer ring 11 being of substantially channel section and the inner ring 12 of T-section. The outer ends 18 of the blades 14 project through openings in the base of the ring 11 and a locking wire 20 is threaded through holes in the projecting ends. Similarly, the inner ends 19 project through openings in the flange of the inner ring 12 and a locking wire 21 is threaded through holes in the projecting ends. A cover-plate 32 is secured to the outer support ring 11 so as to form a cooling air manifold 31 to which air is supplied through duct 30 and from which it passes through the hollow guide blades 14 to discharge radially inwardly of the inner support ring 12. The plate 32 lies over the flange 33 of the outer support ring and under the flange 35, the flange 35 being formed with spaced projections 36 to which the plate 32 is secured by welding, the portions 37 between the projections not being welded. The flange 33 is formed with notches 34 which form openings for the inflow of cooling air from the duct 30. The parts 37 between the welded joints are sealed by applying thereto a coating of stainless steel applied in molten form from a hot metal spray gun. The coating would also in practice be applied over the welded joints at the projections 36. The parts of the blades which project through the slots in the outer and inner support rings are also sealed to the support rings by a sprayed metal coating. Specification 865,545 is referred to.

Abstract: 289,436. Rheinische Metallwaarenund Maschinenfabrik. April 27, 1927, [Convention date]. Addition to 273,338. Projectile fuzes.- The delay-action percussion fuze described in the parent Specification is modified by providing two ignition devices which can be inserted alternatively in circuit with the meams for storing electric energy in the fuze, one of these devices being adapted to operate instantaneously on impact, and the other with delay. In the construction shown, there is provided a condenser a which is connected to contacts a<1>, a<2> by means of which the condenser is charged from a source of current before or during the firing of the projectile from a gun. In the discharging circuit of the condenser there is a switch b, adapted to be closed on impact, and two ignition devices d<1>, d<2> either of which can be connected, by means of a switch c, in series with the switch b across the electrodes of the condenser. The device d<1> is adapted to effect, ignition only when a predetermined time has elapsed after the closing of the contacts b, and may consist of a hot-wire primer, in circuit with a high resistance, or may comprise a spark gap associated with a delay-action device; the device d<2>, on the other hand, which preferably consists of a spark primer, acts immediately the contacts bare closed. A quickaction hot-wire primer may be used as the device d<2>. The switch c may be arranged so that both devices d<1>, d<2> can be connected to the condenser together, so that the device d<1> acts if the device d<2> fails to act immediately after impact. The switch c may also be so devised that its contact member remains in the open position after the fuze has been set for either instantaneous or delayed action, and is closed automatically by inertia when the projectile is fired from a gun.

Abstract: 533,841. Surface treatment of magnesium and its alloys. MAGNESIUM ELEKTRON, Ltd. April 20. 1939, No. 11963. Convention date, Sept. 2, 1938. [Classes 82 (i) and 82 (ii)] In a process for the surface treatment of magnesium and magnesium base alloys for the purpose of forming a protective coating, the metal is subjected to the action of an aqueous solution of one or more alkali metal or ammonium salts of the saturated and unsaturated fatty acids, including the iso-fatty acids, of oxy-fatty acids containing eight or more carbon atoms, of carboxylic acids having two or more carbon rings and their substitution products or phenolates, to form substantially insoluble compounds, at temperatures in the vicinity of or above the boiling point of the said solution, if necessary, under pressure. The solution may contain other solvents such as ethanol or water-soluble sulphates, nitrates, silicates, or chromium or manganese salts. If the alkali or salt used is a dyestuff component, the coated metal is treated with a solution of a suitable coupling component to produce a coloured coating. The process may be applied to magnesium which has already been provided with a protective coating by known methods. In an example, a sheet of magnesium alloy containing 2 per cent. of manganese is heated in an autoclave in a 3 per cent. aqueous solution of potassium palmitate for 15 minutes at a temperature of 170‹C.
