Title: Improvements in road-contouring apparatus
IPC: G01C7/04
Filed: 1920-05-18
Abstract: 168,125. Evans, W. E., (Williams, J. H.). May 18, 1920. Road-contouring apparatus. - The apparatus comprises duplicate friction-driven variable-speed mechanisms for effecting the relative movements of a stylus and a record surface by which the record of the path traversed by the carriage carrying the instrument is made. Two pairs of discs C, D and E, F are driven by gearing from a road wheel &c. and these discs frictionally rotate discs A, B which are slidably mounted on shafts S, P, the positions of the driven discs being controlled by pendulums H, K so that they respectively transmit the horizontal and vertical components of the path traversed to rollers M, N carrying a record-surface, and to a stylus U. Alternatively, the record surface may be fixed and the rotations of the discs A, B may be communicated to bars capable of moving at rightangles to each other, the stylus receiving the resultant of the motions of the bars. The shafts of the driving discs may pass into hollow bosses X and be acted upon by springs so as to permit adjustment of their pressure on the driven discs. Fig. 3 shows one means for connecting the pendulums to the driven discs. The crank-pin I on the pendulum slides between bars S in a crosshead frame t mounted on guides p and carrying. the driven disc A.

Title: Improvement in supercharged two stroke diesel engines
Inventor: ZAKON TZADOK
IPC: F02B37/007
Filed: 1970-03-23
Abstract: 1,261,335. Charging I. C. engines. T. ZAKON. March 23, 1970 [April 16, 1969; Dec. 23, 1969], No. 13802/70. Heading F1B. A supercharged two stroke diesel engine has at least two turbochargers, comprising centrifugal compressors driven by essentially similar gas turbines, which deliver air to a common air receiver an auxiliary blower or low-pressure fan being connected in series with only one of the compressors, each gas turbine being fed by the same amount of exhaust gas and each compressor requiring essentially the same driving power, the delivery pressure of the auxiliary blower or lowpressure fan being chosen so that in operation all compressors not connected to it do not enter a surging regime. Centrifugal compressors 2, 4, Fig. 1 driven by gas turbines 3, 5 supply air to a common scavenge air receiver 7 from which the main diesel engine receives air. Compressor 2 receives air from an electric motor driven fan 1. The gas turbines may be driven by gases from separate or common gas manifolds. When fan 1 supplies compressed air to compressor 2 the rise of the delivery pressure from the latter causes the pressure and weight of air in receiver 7 to rise which results in an increase in the air delivered to the engine cylinders and in an increase in the exhaust gas flow. The mass of exhaust gas driving turbine 5 is greater than the mass of air delivered by the centrifugal compressor 4 and the speed of the turbocharger 4, 5 rises to supply air at a higher pressure. In other embodiments the compressor not supplied with compressed air from an auxiliary blower has a smaller diffusor and the air receiver delivers to under-piston pumps of the engine.

Title: Improvements in or relating to airplanes having changeable thrust direction
Inventor: QUENZLER HENRY HERMAN WALTER
IPC: B64C29/00
Filed: 1962-04-10
Abstract: 961,622. Convertible aircraft. BOEING CO. April 10, 1962, No. 13871/62. Headings B7G and B7W. An aircraft has at least four thrust producing units 35, 36, Fig. 11, operable to exert upward thrust, two of the units being in fore-andaft alignment at the front and rear of a body 32 fixed below a wing 27, the front unit being a propeller unit mounted on a pivot 38 disposed below the wing to locate the propeller but below the upper wing- surface in all positions of the unit when tilted to vary the thrust direction between substantially horizontal and vertical directions. A turbine 44 supplies exhaust gases by a swingable pipe 53, Fig. 12, to port and/or starboard openings 48 having pivotable flaps 60 to produce or correct yaw and pitch. The gases may be directed to rear opening 49 by opening flaps 51 about axes 52, Fig. 13 (not shown), to produce forward thrust or pitch control. Roll control is obtained by utilizing the exhaust from units 35 and having a pivoting hood 67 on exhaust duct 65. In Fig. 11, as in Figs. 1-10 (not shown), which form the subject-matter of Application 14022/61, the power units are arranged symmetrically about the C.G. and the thrust of the units can be balanced automatically or manually to compensate for thrust losses in one or more units, Figs. 17-18 (not shown). The units on each body can be rotated simultaneously by gearing &c., Fig. 19 (not shown), the front propeller thrust direction being nearer the horizontal than the rear thrust direction during the swinging between vertical and horizontal to compensate for the movement forward of the resultant upward thrust of the units during such pivoting. On pivoting from vertical to horizontal, downward flow on the wing leading edge could produce negative lift which can be deterred by providing a pivotable leading edge extension or a slot through the leading edge, Figs. 36, 37 (not shown). In Figs. 38, 39, a plate 100 and lever 107 pivoted at 101 are moved by jack 103 to obstruct air flow down over the leading edge; a switch 113 closed by projection 114 when plate 100 is fully extended causes a jack 111 to open a slot 108; prior to the opening of slot 108, a tab 115 forms an extension of plate 100, but is retracted by spring-biased links 117, 118, 119 when plate 100 is fully extended. Other forms of plate, plate extending means and slot opening means are given in Figs. 41-44 (not shown). Figs. 45-48 (not shown), give various arrangements of power units and their connections to pivotable propellers; some of the power units can be shut down during forward flight. In Fig. 49, two power units 177 drive pivotable propellers at the front and rear of the fuselage 175, the rear propeller can be feathered during forward flight. Pivotable jets 183 on the wing tips provide roll and jaw control. In a seaplane, Figs. 51, 52 (not shown), the rear propeller is fixed in the vertical position and the pitch of the propellers can be adjusted to produce or control pitch.

Title: Improvements in or relating to the analysis of gases containing hydrogen sulphide and sulphur dioxide
Inventor: DENSHAM ALEC BRAMLEY
IPC: G01N33/00
Filed: 1954-05-13
Abstract: The quantity of hydrogen sulphide in a hydrogen sulphide/sulphur dioxide gas mixture is determined continuously by comparing the absorption of infra-red or ultra-violet radiation by the sulphur dioxide in the gas at the start and in the gas after the hydrogen sulphide in it has been catalytically oxidized to sulphur dioxide. This may be done by splitting the gas stream and comparing an oxidized half with an unchanged half and by delaying the unchanged gas stream so that the gases at the analyser are of equal age relative to sampling.  By using analysing cells of different lengths the apparatus can be adjusted so as to give a null balance when the ratio of the gases in inverse ratio to the lengths of the cells.  Dry air of oxygen may be added to remove excess water vapour in the analyser or the water vapour may be condensed out.  Specifications 722,038, 769,995 and 769,996 are referred to.

Abstract: 1,059,415. Lubricating. DAIKIN KOGYO CO. Ltd. April 7, 1964 [April 12, 1963], No.  14343/64. Heading F2A.  A distributing-valve assembly or apparatus in a centralized lubricating system comprises a plunger 2 slidably lodged in a casing 1 provided with lubricant inlet passages 4, 4<SP>1</SP>which are in register with non-return valves 5, 5<SP>1</SP>in the plunger, metering plungers or pistons 3, 3<SP>1</SP>,3<SP>11</SP> being carried in transverse bores in the plunger 2. The transverse bores are in register with one or other of two sets of outlet ports b, b<SP>1</SP>, b<SP>11</SP> and (c, c<SP>1</SP>, c<SP>11</SP>), Figs. 2 to 4 (not shown), depending upon the position of the plunger 2. Similarly, the transverse bores are also in register with one or other of a pair of branched passages a, a<SP>1</SP>. When the plunger 2 is situated adjacent the right-hand end of the casing 1 and pressurized lubricant is admitted through the passage 4, the plunger is displaced towards the passage 4<SP>1</SP> causing lubricant in left-hand end of the casing to displace the metering plungers towards the outlet ports (c, c<SP>1</SP>, c<SP>11</SP>) in succession. The lubricant which serves to displace the metering plungers is subsequently discharged by these plungers through the ports b, b<SP>1</SP>, b<SP>11</SP> when lubricant enters the casing through the passage 4<SP>1</SP> The lubricating system includes a plurality of the aforementioned valve-assemblies connected in series to form a circuit and fed with lubricant by a common pump through a manually or automatically-operated flow-reversing valve. At the end of each stroke of the plunger 2, the valve 5, or 5<SP>1</SP>, which is remote from the passage through which lubricant is being admitted, opens to permit oil to pass through the adjacent transverse bore and passage 4, or 4<SP>1</SP>, to the next assembly in the series.

Filed: 1976-04-08
Abstract: 1501816 Immersion-tube heat exchangers COMMISSARIAT A L'ENERGIE ATOMIQUE 8 April 1976 [18 April 1975] 14402/76 Heading F4A An immersion-tube heat exchanger (Fig. 1) comprises a vessel 1 having inlet and outlet ducts 4, 10 for a primary fluid, and a partition plate 8 dividing the vessel 1 into a lower region 9 at the pressure of the primary fluid and an upper region 18 at the pressure of a secondary fluid, e.g. water, to be vaporized by heat transfer from the primary fluid. Holes in the plate 8 carry vertical immersion tubes for circulation of the secondary fluid. Each immersion tube (Fig. 2) comprises a pressure tube 24 open at its upper end to communicate with the region 18 where the vaporized secondary fluid is collected and closed at its lower end 30 which penetrates the region 9, an axial admission duct 22b for supplying secondary fluid in the liquid phase to the interior of the pressure tube 24, an intermediate tube 23 coaxial with the admission duct 22b, and a sleeve 40 coaxially mounted in the annular space between the intermediate tube 23 and the pressure tube 24, the upper end of the sleeve 40 being rigidly fixed to the intermediate tube 23 at 41 to provide an annular space 43 between the sleeve 40 and the intermediate tube 23. In use, this space 43 becomes filled with stagnant vapour which forms a thermal insulation. Holes 39 are preferably formed in the wall of the intermediate tube 23 and at a higher level than that of the lower end of the admission duct 22b so that unvaporized secondary fluid circulating upwardly outside the intermediate tube 23 can be freed from the vapour phase and return through the holes 39, thus heating the liquid in the admission duct 22b and allowing superheating of the vapour as it travels up the annular space 45 between the sleeve 40 and the pressure tube 24. As shown, the upper region 18 of the vessel 1 contains a heat-insulated admission manifold 21 from which extend injector tubes 22a, the end portion of each injector tube 22a penetrating each admission duct 22b.

Abstract: 670,770. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 9, 1950 [June 14, 1949], No. 14443/50. Class 40 (iv). In a system in which a selector KS1 locates a multipled outlet identified by a resistor R1, R2 ... (or impedance) corresponding in value to a resistor R11, R21 ... previously selected by a register marking switch MS1, false seizure of an outlet already engaged by a similarlycontrolled selector KS2 and consequently exhibiting an apparent resistance of twice its true value is avoided by arranging the highest identifying resistor to be less than twice the value of the lowest resistor. As shown, the resistors are compared by a differential relay D1 which controls the selector drive magnet DM1. Erroneous effects due to earth leakage are minimized by the use of low potentials at the tested outlets, the internal resistance of the relay being at least <SP>1</SP>/ 10 th of the lowest identifying resistor. Alternatively a modulating differential relay may be used in which the two windings from part of the inductance circuit of a high-frequency oscillator. The relationship between the currents in the windings then deter. mine the output frequency which is applied over a narrow band-pass filter to a sensitive relay controlling the drive magnet. The Specification also mentions the use of electronic test devices of the kind described in Specifications 662,215, [Group XL (c)], 666,445, [Group XXIX], and 670,763.
Patent GB-801380-A (GB)
Title: Preparation of tetravalent uranium compounds
IPC: C01G43/00
Filed: 1945-06-07
Abstract: Tetravalent uranium compounds are prepared by treating a solution of a uranium salt in which the uranium has a valency greater than 4 with hydrogen in the presence of a platinum, palladium or rhodium metal catalyst, at ordinary or elevated temperatures and pressures.  The uranium salt may be an organic salt such as uranyl acetate or inorganic such as uranyl nitrate, carbonate or sulphate.  The catalyst may be employed in finely divided form if desired on a carrier such as a carbon, kieselguhr, pumice, or alumina.  The uranium compound may be wholly or partly in solution and the tetravalent uranium compound produced may be recovered by treatment with hydrofluoric acid or a water soluble fluoride, thereby precipitating uranium tetrafluoride or, for example, potassium uranium fluoride. According to examples: (1) uranyl acetate was dissolved in dilute sulphuric acid containing 0.5 parts of palladium black supported on active charcoal and the mixture was agitated rapidly and hydrogen introduced until absorption thereof stopped. The catalyst was filtered and the tetravalent uranium was precipitated as potassium uranium fluoride by the addition of potassium fluoride; (2) a uranyl carbonate solution was rendered acidic by means of acetic acid, and hydrogen was reacted therewith in the presence of a platinum on active charcoal catalyst.  Potassium uranium fluoride was precipitated by the addition of potassium fluoride.ALSO:Uranium acetate is produced by reducing uranyl acetate in aqueous solution by hydrogen in the presence of a platinum, palladium or rhodium catalyst which may be supported on carbon, kieselguhr, pumice or alumina.  The initial solution is preferably rendered acidic.  According to an example, uranyl acetate was dissolved in dilute sulphuric acid containing palladium black supported on activated carbon.  The mixture was agitated and hydrogen passed in under a light pressure.  On cessation of hydrogen absorption the catalyst was filtered off.
