Title: Process for the production of mixed fertilisers composed of ammonium nitrate and ammonium sulphate
IPC: C05C1/00
Filed: 1930-10-09
Abstract: In the production of mixed fertilizers composed of ammonium sulphate and ammonium nitrate, sulphuric acid, nitric acid, and ammonia are brought together in such a way that the heat reaction suffices to evaporate the water also introduced, so as to obtain a saline mixture of the desired composition in a single step.  The nitric and sulphuric acids may be introduced as a mixture, prepared for example as described in Specification 349,998, or they may be introduced separately.  The ammonia may be employed in the gaseous, liquid, or dissolved state.  In starting the saturator, a liquor saturated with the components ammonium sulphate and ammonium nitrate may be employed so that on introducing the reactants a salt of the desired composition is obtained directly.  It is preferable to employ an excess of acid especially nitric acid.  The operation can be carried out under reduced pressure, the evaporation then occurring at a lower temperature.  Inert gases such as air may be passed into the liquid or over its surface.  Such inert gases may also be used to dilute the gaseous ammonia.  The saturator may be constructed wholly or in part of ferrosilicon, phenol-formaldehyde condensation products or ceramic materials high in silica and suitable cements comprising waterglass. Reference has been directed by the Comptroller to Specification 349,998.ALSO:In the production of mixed fertilizers composed of ammonium sulphate and ammonium nitrate, sulphuric acid, nitric acid and ammonia are brought together in such a way that the heat of reaction suffices to evaporate the water also introduced, so as to obtain a saline mixture of the desired composition in a single step.

Patent GB-658256-A (GB)
Title: Process for the manufacture of activated oxide gels
IPC: B01J20/08
Filed: 1947-11-14
Abstract: Oxide gels are prepared by treating a solution of a metallic salt or a metallic hydroxide sol and an organic compound with an oxidizing acid to precipitate a mixed gel of oxide or hydroxide and organo-oxide compound, separating this mixed gel from the mother liquor, destroying the organic portion of the gel by oxidation heating, and activating the resulting oxide.  The process is applied to the oxides of aluminium, iron, nickel, cobalt, chromium, cerium, titanium, zirconium and silicon (silicon being construed as a metal). The organic constituent is correlated with the oxide, if the latter is acidic the organic compound has an amine function, e.g. gelatine, whilst if the oxide is basic the organic compound has a phenol or acid function, e.g. tannin or humic acid, but starch may also be used, e.g. for alumina.  After separating the mixed gel from the mother liquid the washing of the gel is controlled to leave a portion of the mother liquor for oxidizing the organic part of the gel during the heating thereof.  The mixed gel is precipitated between 50 DEG and 100 DEG  C., and the activation of the oxide is effected by heating at 300 DEG  to 550 DEG  C.  Nitric acid is the specified acid.

Title: Shrouded-blading for turbines or compressors
IPC: F01D5/22
Filed: 1962-08-08
Abstract: 979,392. Turbine and compressor blades. BROWN, BOVERI & CO. Ltd. Aug. 8, 1962 [Aug. 10, 1961], No. 30340/62. Heading FIT. Shrouded blading for turbines or compressors comprises a shroud having separate shroud plates attached to the blades, the blades displaying in the non-working and working conditions a torsional prestressing which presses the shroud plates of adjacent blades against one another in the circumferential direction. The shroud plates 2 are parallelogram shaped having edges of contact 4, 5 and surfaces of contact 6, 7 with adjacent plates. The blades have in the assembled condition a torsional prestressing which tends to twist them in a clockwise direction and increase the angle between the edges 4, 5 and the line 8 running parallel to the rotor axis so as to press adjacent shroud plates 2 together and damp oscillations. To compensate for thermal expansion the tangent of the angle is greater than the coefficient of friction between the surfaces of contact 6, 7. Surfaces 6, 7 may be treated to reduce friction. The invention is applicable to both stator and rotor blades.

Title: Improvements in reversing regenerative furnaces
IPC: F27B3/00
Filed: 1921-11-15
Abstract: 193,129. Wade, H., (Blaw-Knox Co.). Nov. 15, 1921. Gaseous-fuel furnaces.-In reversible regenerative furnaces, the fuel is delivered through a ported structure which, after reversal is effected, is shielded from the issuing products of combustion. The ported structure may also be provided with air-passages arranged between the fuelpassages in such a manner that the fuel and air are thoroughly mixed as they enter the furnace. Figs. 1 and 2 show an open-hearth furnace with the ported structure comprising a refractory body 8 provided with passages 9, 10 and supported in a water-cooled frame 7 arranged at the dischargeopening of the gas-port 2, air for combustion being supplied mainly through the ports 4. An auxiliary port 11 in the ported structure receives pre-heated air from the chill 13 and a flexible connection 12 or, if desired, the port 11 may besupplied with natural, coke-oven or water gas. At the opposite end of the furnace the ported structure is shielded by raising it to the position indicated by dotted lines in Fig. 1. To reduce the supply of fuel, the ported structure may be raised slightly so as to close the ports 9. In the modification shown in Fig. 5, the ported structure 16 is arranged in the discharge-port of the airuptake 18 and is provided with one or more ports 17 containing refractory cones 19 into which water-cooled oil pipes or burners 20 discharge. The refractory cones 19 may be omitted, in which case the discharge ends of the burners would be located in the plane of the outlet ends of the ports 17. A modified form of ported structure 22 for use with natural gas is shown in Fig. 8. Air from the uptake 24 passes through passages 23 in the ported structure, when lowered, and meets gas issuing from nozzles 25 supplied from the pipe 27 and arranged between the air-passages. Fig. 9 shows a further modification, in which air from the uptake 29 passes to the furnace through passages 31, while gas is supplied through pipes 32 to headers 32<a> communicating with the ports 33. In the modification shown in Fig. 11, air from the uptake 38 passes through main and auxiliary ports 36, 37 in the ported structure, and gas from the uptake 41 passes through ports 40. The ported structures at each end of the furnace are interconnected by cables and counterbalance one another so that their simultaneous operation is facilitated.

Title: Improvements in automatic thermostatic control devices for auxiliary starting carburetters for internal combustion engines
IPC: F16H55/08
Filed: 1948-11-25
Abstract: 673,537. Spray carburetters. SOLEX. Nov. 25, 1948 [July 17, 1948], No. 30636/48. Class 7(iii) A control for a starting carburetter comprises a thermally responsive device 14 situated adjacent an electric heater 15 comprising either a single resistance fed by two separate circuits 24, 16, or two resistances arranged in separate circuits, the circuit 24 being closed by a manually operated switch 26 whilst circuit 16 is closect at a predetermined temperature by a thermally responsive switch 19. As shown the device 14 comprises a bimetallic strip connected to a member 7 controlling the operation of a starting carburetter 13, as described in Specification 673,542, and the device 19 is positioned at some point, such as the cylinder head or exhaust pipe, indicative of engine temperature. When starting from cold, the strip 14 holds the member 7 raised to bring the carburetter 13, fed with fuel through a passage 5 and orifices 11, 12, into operation. Closing of the switch 26, sends current via circuit 24 to the heater 15, which causes the strip 14 to gradually move the member 7 down. As the engine warms up, the switch 19 closes and finally the member 7 closes the carburetter outlet 13 to render it inoperative. When the switch 26 is broken to stop the engine, current still flows through circuit 16 to the heater 15 to hold the starting carburetter inoperative on restarting provided the engine is warm enough to keep the switch 19 closed. Resistances 23, 27. in the circuits 16, 24, may be arranged so that when the switch 19 closes, the current through the heater 15 is increased to accelerate the shutting off of the carburetter 13. In a modification, each of the circuits 16, 24, contains an electric heater situated adjacent the member 14. The Specification as open to inspection underSection 91. also describes the annlication of the device to a choke valve. This subject-matter is not included in the specification as accepted.

Abstract: 1468546 Pulse doppler radar MARCONI CO Ltd 12-May 1975 [11 July 1974] 30688/74 Heading H4D A pulsed doppler radar uses injection phase priming of a pulsed oscillator 1 in an attempt to achieve pulse to pulse coherence. Noise phase modulation however causes the phases of successive pulses to randomly vary about a mean phase. To overcome this the phase of each pulse is detected and used to vary the triggering instant of the oscillator. The local oscillator 7 produces, via coupling 9, the injection signal for the oscillator via circulator 3. The transmitted pulse, as leaked through duplexer 4, together with any doppler shifted echoes, is changed to IF by means of the local oscillator and mixer 6, and the phase of the pulse and echoes determined by detector 11 using the frequency multiplied output of trigger generator 14 as reference, via calibration phase changer 12. A sampler 16, controlled by the trigger pulses, separates out and stores the phase of the transmitted pulse so that this can be used, via stabilizing circuit 18, for controlling the oscillator modulator via variation of the triggering pulses.

Abstract: 1,218,698. Laminating thermoplastic film. A. L. JAMES. 17 June, 1969, No. 30706/69. Heading B5N. A film of thermoplastic material is rendered polar on one surface by gas flame or corona discharge and pressed into contact at that face with a substrate of different material to form a chemical bond at a temperature below the heatsealing temperature of the film and not above 150‹ F., the pressure being sufficient to expel air from between the sheets. The film may be oriented polyethylene and the substrate may be kraft paper, paperboard, cellulosic plastics, glassine paper, sulphite paper, ground wood sheet, metal or thermoplastic sheet. The pressure causes cold flow of the thermoplastic film into any interstices in the substrate; it may be applied to a roller assembly provided with cooling means. Prior to lamination the film may be printed and stretched. Paper substrates may be supplied uncalendered and calendered during the pressing. Lamination may be at elevated temperature as specified above, or at room temperature followed by ageing to allow completion of the bonding reaction. Substrates may be bonded to both sides of a film using the above process.
