IPC: B64F5/00
Filed: 1949-12-06
Abstract: 703,239. Making aircraft wings. FAIREY AVIATION CO., Ltd. March 28, 1950 [Dec. 6, 1949 No. 31272/49. Classes 83 (2), 83 (3) and 83 (4). [Also in Groups XXIII and XXXIII] In a method of making a complex structure of sheet material, such as an aircraft wing, the component parts of the skin of the structure are brought to their finished shapes, mounted in a lofting apparatus relatively to a datum line and marked out relatively to said datum line. The lofting apparatus comprises a datum beam 28, Figs. 1 and 6, on a sprung carriage 29, with screw adjustment for levelling purposes. A carriage 33, slidably mounted on the machined and surfaced top of the beam 28 and which may be clamped in any position thereon by a clamp 36, comprises an upper part 37 which may be set angularly relatively to a lower part 38 through a range of 360 degrees and clamped in position by a screw 39. Fine setting of the carriage longitudinally on the beam is achieved by a threaded shaft 54 operated by hand wheel 55. The part 37 carries a tower 41 mounted at one side on a spindle 42 and having at the other side clamps 43 on a rod 44 whose ends pass through quadrants 45, allowing the tower to be set at any angle between 0 degrees and 90 degrees to the beam. The quadrants are mounted eccentrically on a bar 57 rotatable by a tommy bar 57a and clamped' by clamps 59, to provide a fine adjustment of the angular position of the tower. For positions of the tower away from the vertical its free end may be supported by a jack. The beam 28 is positioned from a support beam 20 for the curved skin structure 21 by fixed and movable spacing blocks 49, 50, respectively, having locating pins, the beams being then bolted together. The side edges 48 of the tower are machined and surfaced to constitute a surfaceplate for scribing means. Drilling; jigs; riveting.-In a modification, Figs. 14 and 15, a backing plate 70 for a jig is held on the beam 20 and is marked out and drilled with holes 71, all of the same size irrespective of the size of the rivets to be employed in the structure. Curved skin panels 74 are then located and clamped within the jig and the internal members such as spars and ribs 75 are similarly set up and clamped. Drilling is then performed by a combined drill and countersink 79, 80 guided by a sleeve 77 which engages with a hole 71. Rivets are then inserted and set and the heads faced off by a small milling cutter also operating within the sleeve 77. Stamping.-Shallow curvatures may be imparted to the skin panels by. forcing them into the curved jig template, and leading edge and like deeply curved sections may be curved prior to their insertion into the jig by a punch 87, Fig. 11, having a body of laminated paper impregnated with a synthetic resin and a nose 88 of laminated impregnated fabric, forcing sheet metal 83 into a channel-shaped structure against a rubber sheet 84. Specifications 703,305 and 703,306 are referred to.
Patent GB-781831-A (GB)
Title: Process for desulferizing mixtures of hydrocarbons
IPC: C10G29/04
Filed: 1955-11-02
Abstract: Sulphur-containing hydrocarbons are desulphurized by contacting at a temperature of 50-200 DEG  F. with finely-divided silver.  The sulphur compounds chemisorbed on the silver are then separated from the hydrocarbons.  The silver may be colloidal silver, of particle size less than 1 micron, which may be deposited on a carrier having a high surface area.  Carriers referred to are natural clays, e.g. montmorillonite and bentonite; metal oxides such as alumina, magnesia, zirconia and titania; silica gel; silica-alumina and silica-magnesia cracking catalysts; activated charcoal such as cocoanut charcoal; carbon blacks; and a carbonaceous material produced by air oxidation of coke produced by the fluid coking process.  Alternatively, a silver-adsorbent mixture may be used which is prepared by impregnating carbon with aqueous silver lactate, drying and reducing the lactate to silver metal by contacting with hydrogen.  The contacting time may be 5 minutes-3 hours and at least 8 parts of silver per part of sulphur present may be used.  Petroleum hydrocarbons may first be partly desulphurized by other processes, e.g. hydrodesulphurization, contacting with metals, e.g. Na, K and Ca, treatment with sulphuric acid or aluminium chloride, or extraction with aqueous boron fluoride.  The silver may be freed from sulphur compounds by contacting, at 200-700 DEG  F., with a gas or vapour, e.g. nitrogen, hydrogen, chemically inert gases, steam, water gas and hydrocarbon vapours, e.g. methane and ethane.  Sulphur compounds difficult to remove from the silver may be removed by an additional process such as stripping at high temperatures with or without oxidation agents, e.g. heating at 800-1200 DEG  F. in air and reducing the silver oxide formed to silver in hydrogen or carbon monoxide at 500-1000 DEG  F.; contacting at 50-200 DEG  F. with an oxidizing agent, e.g. hydrogen peroxide, ozone and per-acids, e.g. perphosphoric, permolybdic, pertungstic or performic acids, hypochlorites such as sodium hypochlorite or hypochlorous acid, and reducing the silver oxide to silver with an aqueous reducing solution such as hydroxylamine, or with hydrogen; or treating with weak acids such as formic, oxalic or acetic acids and reducing the silver oxide with hydrogen.  The hydrocarbons treated may be petroleum fractions boiling up to 500 DEG  F., for example gasoline. In the example a petroleum naphtha fraction boiling in the range of 175-350 DEG  F. is contacted in liquid phase at 75 DEG  F. with 10 per cent silver on activated alumina.

Abstract: 1392469 Electronic taximeters KIENZLE APPARATE GmbH 6 July 1972 [13 July 1971] 31839/72 Heading G4T An electronic taximeter includes stores ZS11-ZS16 for summing respective types of data, pertaining to the operation of the taxi over a period, manually closable switches TS11-TS16, for transferring the data from a selected store on to line 28, and a key-operated multi-position switch 30 for selectively routeing the data on line 28 to a digital display 37/38, a tape recorder 39, a calculator 41 or a reset device 44. As shown, distance pulses, produced by means 18-22, are fed to a binary reduction device 23, the output of which is representative of fare increments and is determined by the tariff selected at S1-S4. This output and time pulses from an oscillator Z enter a circuit FF, G, D2, D1, which as described in Specification 1,129,344 gives an output equivalent to the faster of the two inputs; this output is fed to ZS16, which totalizes the fare increments over a period, e.g. a shift or a week, and also via normally-closed switch 31, line 28, switch 30 and line 32 to the display 37/38 to indicate the "running fare". If the number of time pulses exceeds the number of distance pulses in any period, the excess number of time pulses appears on line a 2  and is fed to ZS15, which totalizes waiting time. The pulse output from a binary reduction device 24 is representative of actual distance (i.e. is independent of tariff), and is fed to "total distance" store ZS14 and, when AND G2 is open, the "occupied distance" store ZS13. AND G2 is open whenever switch 26 is in its closed, "taxi hired" condition. Each closure of switch 26 also steps the "number of hirings" store ZS12. Store ZS11 totals "extras", each unit charge of which is entered by closing switch 27.  During each hiring, the fare is transferred over line 45 and recorded at 39. Also all data being recorded at 39 is displayed at 37/38 via line 40. When switch 30 directs data from the stores ZS11-ZS16 to the calculator 41, subtotals are derived and recorded via line 42 and displayed via line 40. When switch 30 connects the stores ZS11-ZS16 to the reset device 44, the totals held by the stores are recorded via line 43 and displayed via line 40, and the stores are reset to zero.

Abstract: 537,047. Counting-apparatus. HIGHFIELD, J. S. Dec. 12, 1939, No. 32056. [Class 106 (i)] [Also in Group XXXVI] In a two-part tariff meter where a registering gear train is driven by the meter to register total consumption and a second train registers excess consumption over a pre-determined rate, the second train being driven from the planet carrier of an epicyclic gear one sun wheel of which is driven from the meter and the other from a constant speed device, a simple setting device including a flexible member is provided to vary the ratio of the drive from the constant speed device to its sun wheel. The invention is described as applied to a two-part tariff electricity meter of usual construction 4, 5, 6, 7 the spindle 9 of which drives one set of register dials 8 through a shaft 10. This drive is also communicated by bevels 12 to one sun wheel A of a differential gear the other sun wheel B of which is driven through intermittent gearing from a clock or constant speed motor 13. The planet wheel C is mounted on a carrier 14 the shaft 15 of which is fitted with a disc 16 carrying a pawl 17 co-operating with a wheel having one ratchet tooth 18. The disc 16, pawl 17 and ratchet 18 constitute a one-way clutch arranged to drive through bevel gear 19 a second set of register dials 20 which registers only the excess consumption above the normal maximum demand for which the apparatus is set. The motor 13 drives through reduction gear 22 a crank 21 which through a jointed link 23 rocks a bell-crank lever 24 loose on shaft 25 to and fro through a right angle. Loose on the shaft 25 is an arm 27 carrying a pawl 28 engaging the teeth on a ratchet wheel 26 fixed to the shaft. A pin 30 on the end of the arm is connected to the bell-crank 24 by a light spring 29. The arm 27 is adapted to engage a pin 31 on the part 24. The extent to which the wheel 26 is driven for each revolution of the crank 21 is determined by an adjustable radial pointer arm 32 which may be adjusted by hand over a scale 35, a pointer 34 registering the adjustment. This pointer arm is held frictionally in any adjusted position. As the arm 27 rocks to drive the ratchet wheel, it meets a pin 33 on the arm 32 and is held, the further movement of the bell crank 24 only serving to tension the spring. The drive from the ratchet 26 is transmitted through bevel gear 40 to the sun wheel B. Normally the sun wheel B rotates faster than A and there is no drive through the one-way clutch to the second meter. If, however, the wheel A should go faster because of the normal demand being exceeded, the planet carrier turns in a direction to operate the one-way clutch to the second meter.
