Title: Compression-ignition engines
IPC: F02B37/04
Filed: 1972-05-23
Abstract: 1386676 Starting I C engines SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES 23 May 1972 [25 May 1971] 24288/72 Heading F1B A compression ignition engine I with exhaust driven turbo-compressor 3, 5, heat exchanger 7 and volumetric compressor 10 has an electric motor 24 to drive compressor 10 during cold starting, the compressor 10 being connected to the engine crank-shaft 14 via a clutch or freewheel 23 and a variable speed transmission 15-19, so that the electric motor can rotate the compressor 10 faster than it could be rotated by the engine. In very cold conditions, the motor 24 is first energized with solenoid operated valve 30 open causing a rise in the pressure and temperature of air entering manifold 12 and after two seconds starter motor 27 is energized. This produces a fall of manifold pressure but the temperature continues to rise. The valve 30 is then closed, leading to a sharp rise in manifold temperature and pressure and starting of the engine. Motor 24 is now connected as a dynamo and is driven by engine 1 through clutch or free-wheel 23. For normal cold starting the valve 30 remains closed throughout as it does also for starting the warm engine, in which latter case the unit 24 remains connected as a dynamo.

Title: Improvements relating to Superconductors
IPC: H01L39/00
Filed: 1967-06-01
Abstract: 1190817 Coating with metals COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT 1 June 1967 [1 June 1966] 25433/67 Headings H1A A5 and A4D A Type II super-conductor, which may be an inter-metallic compound, is made by depositing one of two constituents, which together form the type II super-conductor, on a support and covering it with the other constituent by hot-dipping. The Type II super-conductor may then be formed by a heat treatment which homogenizes the constituents. At no time is the super-conductor or its constituents allowed to come under tension. A protecting sheath around the Type II superconductor and its support may be applied before homogenizing and a layer of metal be deposited over the sheath. Ribbons of stainless steel, nickel, nickel alloy, of molybdenum or of members of the platinum family or braids of ceramic fibre may be used as supports, or a metal billec may be placed in a sheath or tube and rolled with it to produce a composite strip with a core of the supporting metal and an exterior layer of a constituent of the Type II semi-conductor. Niobium, tantalum and vanadium may be deposited on the support by vacuum deposition, by decomposition or pyrolytic reduction of a compound, by chemical means or by flame spraying. The support so coated is passed through a bath of liquid aluminium, gold, gadolinium or tin, and the deposit of metal so formed is homogenized with the earlier one by heating. A sheath of metal may be placed over the coated support before the heat-treatment, a metal which is highly electrically conductive at normal temperatures is plated on to the sheath, suitably by electro-plating, and electrically insulated by coating with a liquid plastics resin or by lapping with a braid or ribbon of a plastics material resistent to very low temperatures, such as a polyamide or terephalate. Details are given of how a stainless steel support may be coated with niobium, by pyrolytic decomposition of NbI 5  or by rolling of a composite billet, dipped in tin, heat-treated, sheathed in stainless steel and given an outer coating of copper or silver. The method of the invention may be employed to produce Nb 3 Sn, V 3 Ga, Nb 3 Au, Nb 3 Al, Ta 3 Ga, Ta 3 Al, Nb 3 Ga, V 3 Sn and V 3 Al. Preferably the support is coated on one side only, and is kept curved, with the deposit on its concave side, throughout the coating operations, so that the super-conducting material is not brought under tension.
Patent GB-382704-A (GB)
Title: Improvements in processes for coating non-metallic substances with metals
IPC: C23C18/26
Filed: 1931-09-11
Abstract: Non-metallic substances, other than rubber and products of cellulose esters or cellulose ethers, are coated with metals by treating them with a reducing solution, the solvent of which gently swells the substance, without obstruction by the reducing agent, drying the substance with the reducing agent firmly embodied in its surface, and immersing the substance thus treated in a reducible metallic salt bath for the purpose of depositing firmly adhering metal thereon. Parts of the article which are not to be metallized are covered with a protecting coat of cellulose ester varnish, asphalt-lac, or the like, which is subsequently removed together with the superimposed metallic layer.  Suitable substances for metallizing mentioned are celluloid substitutes such as casein-, albumin-, phenol-, urea-, thiourea-, and formaldehyde condensation products.  For metallizing casein products, hydroquinone, p-aminophenol, or p-phenylene-diamine, dissolved in water, may be used as reducing agent; for albuminous products, a reducing aromatic compound containing amino groups, e.g. p-amino phenol or p-phenylene-diamine, dissolved in water, is employed.  Phenol condensation products require acetone and a mixture of hydroquinone and catechol or pyrogallol, while urea and thiourea products require boiling aqueous solutions of hydroquinone. Specifications 311,766 and 330,677, [both in Class 82 (ii), Washing granular &c.], are referred to.

Title: A process of heat treatment of precipitation hardening alloys for permanent magnets in a magnetic field intended to create a direction of preferred magnetisation
IPC: C22C38/10
Filed: 1948-09-30
Abstract: Anisotropic magnets are produced from precipitation hardening alloys by heating to a temperature sufficient to dissolve the precipitating constituent or constituents, e.g. 1200 DEG C., quenching in a metal or salt bath at a temperature between the precipitation temperature and the Curie point and applying a magnetic field during the time the magnet is in the quenching bath.  In one process an alloy for magnets consisting of 5-10 per cent Al, 10-30 per cent Co, 10-25 per cent Ni and if desired up to 10 per cent of Cu and/or Ti the remainder being iron, is quenched in a metal or salt bath maintained at a temperature between 600-900 DEG C.  A constant or alternating magnetic field is applied during quenching after which a moderately accelerated cooling, as by a gentle air blast, is carried out, followed by the usual precipitation hardening treatment.
