Inventor: CULVER LEONARD JAMES
IPC: F22B1/18
Filed: 1963-08-20
Abstract: 1,063,269. Steam boilers combined with air-conditioning plant; refrigerating. FOSTER WHEELER Ltd. Aug. 12, 1964 [Aub. 20, 1963], No. 32925/63. Headings F4A and F4H. In an auxiliary steam raising system for motor ships the exhaust gases from the engine are used to produce high- and low-pressure steam, the low-pressure steam being used to operate an air-conditioning plant. An oil-fired boiler 10 generating high-pressure steam has heat-exchange tubes 13 which are supplemented by a heat exchanger 14 mounted in a trunking 12 through which the exhaust gases pass. Steam from the boiler may be taken directly from a pipe 32, or be passed through a superheater 34 also mounted in the trunking, or be supplied to a low-pressure steam pipe 22 through a pressure-reducing valve 36. A separate lowpressure steam generator comprises a drum 20 and a heat exchanger 18 mounted in the trunking. Low-pressure steam is supplied to an ejector 24 connected to a flash chamber 26 from which chilled water is circulated by a pump 27 to an air-conditioning unit 28, the effluent of which is returned to the flash chamber. The effluent of the ejector is collected in a condenser 30 from which it is pumped to provide make-up water for the flash chamber and to a tank 42 where it provides feed water for the boiler 10. A calorifier 46, which may be thermostatically controlled, may be used to heat the water supplied to the air-conditioning unit. Additional heating for the low-pressure boiler may be provided by fitting a heating coil, supplied with high-pressure steam, in the low-pressure boiler drum 20.

Title: Method of producing high quality silicon for electric semiconductor devices
IPC: C01B33/02
Filed: 1958-10-17
Abstract: <PICT:0851290/III/1> Silicon is produced by the interaction of a silicon halide, e.g. silicon tetrachloride, and atomic hydrogen at normal or elevated temperature, e.g. 200-300 DEG C.  The atomic hydrogen may be produced by the passage of an electric discharge through molecular hydrogen at a pressure of 1 m.m.  The discharge may be produced by an alternating current of 3000-5000 volts.  The silicon halide may be vaporised at a thermostatically controlled temperature, and in addition may be mixed in the vapour state with molecular hydrogen before contact with the atomic hydrogen.  The silicon produced may be deposited on a rod, which may be inductively heated, and may be rotated and withdrawn from the reaction zone as deposition of silicon proceeds.  As shown hydrogen passes through a U-shaped discharge tube 1 from a valved inlet 5 into a reaction tube 2 where it is admixed with vaporous silicon halide admitted through a concentrically arranged tube 7 from a vaporising vessel 9 heated to a thermostatically controlled temperature.  The silicon produced is deposited on a carrier 14 heated by an induction coil 15.  The reaction product gas passes through a separating vessel 11, a freezing-out trap 12, a valve 13, and a vacuum pump (not shown).

Title: Improvements in and relating to the recovery of aluminium chloride
IPC: C01F7/62
Filed: 1921-12-12
Abstract: 191,582. Haddan, R., (Gulf Refining Co.). Dec. 12, 1921. Aluminium chloride is recovered in substantial amount without the use of chlorine by distilling the hydrocarbon residues obtained in processes for the treatment of oils with aluminium chloride. Free hydrocarbons are first removed and condensed, and on raising the temperature, preferably to 1450‹ F., aluminium chloride is evolved. Bv treatment with chlorine or hydrochloric acid gas a further quantity of aluminium chloride may be obtained. The yield is increased by adding, preferably after the removal of the hydrocarbons, a small quantity of aluminium or an aluminium compound such as the carbide or sulphide. Chlorine compounds which may be evolved during the heat treatment may also be conserved by passing them together with the aluminium chloride, over aluminous material before they enter the condensers. In Fig. 1, the material is heated in the retort A and the hydrocarbons removed through the pipe I. The aluminium chloride which is evolved at a higher temperature, is condensed in the chamber K and is collected in the receptacle U. The apparatus shown in Fig. 3 is used when it is intended to pass chlorine or hydrochloric acid after the heat treatment. The material is heated in the retort 1, the hydrocarbons condensed in the pipes 16, and the aluminium chloride collected in the chambers 21, 22. The chlorine &c. is introduced into the retort through the pipe 10.

Abstract: 1,004,499. Handling device for radio-active articles. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 20, 1964 [Aug. 22, 1963], No. 34118/64. Heading B4Q. A device for tilting elongate radio-active articles, e.g. irradiated fuel elements, from a vertical to a horizontal position to facilitate their transfer between hot cells comprises a support 1 fixed to a shaft 12 journalled by bearings 13 in a casing 16. Rollers 5 are supported at intervals along the support 1, the top 7 of the support carrying a device (not shown) for releasing grippers which convey the fuel element 6 to the support. The fuel element 6 (shown in chain-dotted lines) has upper and lower narrow extensions 9, 21 and is lowered by the grippers so that it enters a guide 10 at the lower end of the support. The fuel element is retained on release of the grippers by the engagement of an abutment on the fuel element formed at the upper end of the narrow extension 21 with the lower ends of a stirrup 18 pivoted at 19 on the guide 10. A lever 26 rigid with the shaft 12 carries a counterweight 29 and a further lever 35 rigid with the shaft may be locked by a pawl 37 pivoted at 41 and operated by a lever 40, this pawl being urged into the locking position by a spring 42. A dashpot cylinder 34 connected at 32 to the lever 26 damps the tilting movement about shaft 12. When the fuel element 6 has been deposited on the support 1 and the pawl 37 is released, the fuel element weight overcomes the counterweight 29 so that the support 1 takes up a horizontal position in which it is locked by a further pawl 39. The fuel element 6 may now be removed by pushing it over the rollers 5 since the stirrup 18 swings out of the way. On release of pawl 37 the counterweight 29 returns the support 1 to the vertical.

Abstract: 1,270,556. Railway car buffing and draw gear. ACF INDUSTRIES Inc. 7 July, 1969 [9 July, 1968], No. 34137/69. Heading B7T.  In a combined buffing and draw gear, in which a telescopic hydraulic cushioning gear 36 is arranged in a centre sill, buffing forces, in excess of a predetermined value after compressing the gear 36 by-pass the hydraulic mechanism and are transmitted directly, through the outer cylinder 40, to a flange 30 on a rear stop casting 22, having a separate buff cushion stop surface 26. This protects the gear 36 from damage by high magnitude shock forces in buff and prevents forces from being concentrated at the rear of casting 22. The gear 36 is normally extended, by compressed air in chamber 50, so that shoulders 118, 120 abut lugs 32 and 34 for the direct transmission of draft forces to the sill 14. Buffing forces of low magnitude are transmitted through the hydraulic fluid in chambers 42 and 44 free piston 48, the air in chamber 50 and the curved interface of plates 52 and 116, to the buff cushion stop surface 26. During compressing of the gear 36, metering pin 86 restricts the flow of fluid through orifice 94. Chamber 46 is filled through ports 108. In the fully compressed condition plate 31 abuts flange 30. Draft forces, applied at an intermediate state in the compression of gear 36, are transmitted to the flange 28 through plate 52. Under draft, the return flow of fluid, through ports 108, is throttled, in known manner, by valve member 110.
