Title: Improvements in or relating to high pressure tubular steam generators
IPC: F22B35/10
Filed: 1935-08-12
Abstract: 443,765. Instantaneous steam generators. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Aug. 12, 1935, No. 22664. Convention date, Sept. 22, 1934. [Class 123 (ii)] Water is evaporated at different temperature stages in tube sections 1-5 connected together in series through separators 6-9 from each of which steam is led off through pipes 10-13 to a main separator 14 and water flows to the next section. Throttle valves 37-40 in the steam pipes 10-13 are automatically controlled by the temperature or pressure of the working medium or by any condition thereof associated with the temperature or pressure. A throttle valve may be operated by a piston acted upon by pressure fluid, the supply of which is controlled in accordance with the temperature or pressure of the working medium by the difference in the temperature or pressure at two points of the sections. Further, a throttle valve may be automatically operated by a fluid-pressure relay controlled by the weight of the water collected in the main separator. Throttle valves 37<1>-40<1> between the separators 2-5 and the tube sections may also be automatically controlled in accordance with the temperature or pressure or other associated condition of the working medium.

Abstract: 493,391. Controlling aircraft. FAIREY AVIATION CO., Ltd., and YOUNGMAN, R. T. Aug. 19, 1937, Nos. 22805 /37 and 8155/38. [Class 4] An aircraft flap adapted to be lowered from an aerofoil and to be turned about an axis at or near to its centre of pressure, is adapted so that its leading edge may be raised or lowered until the plane of the flap is substantially normal to that of the aerofoil. In one form, a flap 12 is mounted on a wing 11 by pivoted links 13, 14 in a manner similar to that described in Specification 467,465. A link 15 is pivoted at one end to the link 13 and at the other end to the flap 12 about an axis coaxial with that of the pivot between the link 14 and the flap. The flap is moved bodily from the wing on operation of a worm 17 which drives a worm-wheel integral with the link 13. The pivot between the links 13, 15 is normally locked to the flap by a plunger 42. Operation of a control member 46 withdraws the plunger 42 and simultaneously through a plunger 33 locks sprocket wheel 20 coaxial with the lower pivot of link 14, to the flap. Thus the flap, through chain and sprocket gearing and a lever 26, may be turned about the lower pivot of the link 14. In a modification, a foldable link 48, 49 is pivoted to the flap at or near its centre of pressure and coaxially with the lower end of a link 51, the upper end of which is pivotally mounted on the wing. The flap is moved bodily from the wing on operation of a worm 53 and wormwheel 52 which straightens the links 48, 49. The flap may be turned about the pivot of the links 49, 51 on operation of a worm 61 acting through a worm-wheel 60, lever 59, link 58, bell-crank lever 56 and a link 55 pivoted to the flap. The foldable link may be replaced by an hydraulic jack. A plurality of either or both the above mechanisms may be provided for operating a flap.

IPC: C01B35/06
Filed: 1962-06-15
Abstract: The alkylation of benzene with ethylene is catalysed by a boron trifluoride modified alumina and free boron trifluoride from which sulphur impurities have been removed by passing the fluoride through a liquid hydrocarbon, e.g. benzene, prior to use.  In a specific example, the efficiency of purified and unpurified BF3 is illustrated.  Other boron halides, e.g. BCl3, may also be purified by this method (see Division C1) whilst numerous suitable liquid hydrocarbons together with specific sulphur impurities are listed.ALSO:Boron halides containing sulphur compound impurities are purified by contacting the halide with a liquid hydrocarbon.  The boron halide may be gaseous and contacted concurrently or counter-currently with an anhydrous liquid hydrocarbon at 0 DEG  to 300 DEG  C. and at 1-200 atm., in a batchwise or continuous process. The liquid hydrocarbon may be a paraffin, cycloparaffin or aromatic compound but is preferably benzene.  A specific example discloses the alkylation of benzene with ethylene using an Al2O3-BF3 catalyst with and without the removal of SO2 from BF3. Also disclosed is the purification of BF3 + SO2 with heptane and BCl3 + (CH3)2S with toluene.
