Patent GB-1437083-A (GB)
Title: Vehicle speed limiter
IPC: B60K31/02
Filed: 1972-04-06
Abstract: 1437083 Controlling vehicles P J COAKER 21 May 1973 [6 April 1972 19 Sept 1972 29 Sept 1972] 15805/72 Heading B7H [Also in Divisions G3 F1 and F2] An arrangement for limiting the maximum speed of a vehicle includes a mechanical link whose length can be altered interposed between a speed controlling device (accelerator pedal) and the engine speed control device (throttle valve) where the length of the link is adjusted when the detected road speed differs from the signalled maximum speed. The mechanical link described employs an electric motor 46 to drive through gearing 48 a rotatable screw system 17 which alters the distance between the ends of rods 12 and 16 and thus changes the length of the link between accelerator and throttle. Limit switches are operated by peg 57 to ensure that the motor reverses at the end of the adjustment travel. In operation a maximum speed signal is provided, which might be signalled by radio or ultrasonically and a comparison made between this speed and the actual road speed. If the road speed exceeds the maximum speed signal motor 46 runs to lengthen the link and thus close the engine throttle. When the speed is less than the maximum the motor runs in the reverse direction to shorten the link to allow movement of the throttle setting to a position which gives the set maximum speed regardless of further depression of the accelerator.

Abstract: 823,128. Mine roof supports. DOWTY MINING EQUIPMENT Ltd. May 23, 1956 [Feb. 23, 1955], No. 16012/56. Divided out of 823,127. Class 20(2) Mine roof supports 19 and a flexible coal conveyer extending along the coal face adapted to be moved forward alternately by jacks 35 connected between them are controlled by trip valves 41 on the conveyer operated by movement of a cam 43 with the coal cutter so as to collapse the supports 19 after the coal cutter has passed them, advance the supports and extend them again. The supports are of two kinds arranged alternately along the coal face and a different control valve and jack is associated with each kind. One kind comprises a roof bar supported by two props and the other 17 by three props, and only the jacks associated with the three prop units move the conveyer. A two-prop support immediately behind the coal cutter is moved by its jack when a cam moving with the coal cutter initiates operation of the two-prop support control mechanism and a cable extending behind the coal cutter from this cam is connected to the cam 43 which is drawn along to initiate the operation of the control mechanism of a three-prop support 17 by depressing the plunger 42 of the trip valve 41 which is retained by a latch 91, pressure fluid is thus supplied to extend the jack 35 and move a part of the conveyer forward some distance behind the coal cutter, until the latch 91 is released by a rod 92 and a lug 93 on the jack whereupon pressure fluid is supplied by pipe 54 through the jack rod chamber 55, chamber 56 and control valve 61 to operate a release valve 82 to collapse the props of the support 17 and to contract the jack 35 which advances the support 17 until a stop 68 depresses the plunger 62 of the control valve 61 which supplies fluid to reset the props. The control mechanism of the two-prop supports is similar except that the piston chamber 52 is always connected to exhaust and for the omission of the latch 91 and consequent modification of the trip valve.

Patent GB-833624-A (GB)
Title: Selective precipitation of uranium phosphate
IPC: C01B25/28
Filed: 1951-07-06
Abstract: Uranium is selectively precipitated as phosphate from a sulphuric acid solution containing dissolved uranium and a much larger concentration of dissolved silicates, iron salts, aluminium and alkaline earth metal salts by treating the solution with a metallic reducing agent to reduce the dissolved uranium to the quadrivalent state, and the iron to the ferrous state and thereafter adding a water-soluble phosphate to the reduced solution.  The initial solution normally results from sulphuric acid leaching of a lowgrade uranium ore or from a sulphuric acid solution of a precipitate obtained by neutralization of acid leach liquor from such an ore. The preferred reducing agent is metallic iron in which case the pH of the leach liquor should be from 1 to 1.5, but a Jones reductor, zinc or aluminium may be used.  Precipitation may be effected by disodium or diammonium phosphate or pyrophosphate in amounts up to twice the stoichiometric amount to precipitate the uranium.  The uranous phosphate precipitate may finally be treated with alkali metal hydroxide to convert it to uranous hydroxide.  According to examples: (1) precious metals were extracted by cyanide leaching of an ore and the wet ore residue was reacted with sulphuric acid in the presence of manganese dioxide so that the iron dissolved was converted to the ferric state and the final leach pH was 1.5. An aqueous slurry of limestone was then added incrementally, bringing the pH to 3.3 and precipitating most of the dissolved iron.  The solution was then treated with concentrated sulphuric acid and iron powder with agitation at a pH of 1.1 whereupon the uranium was converted to the uranous state.  Excess iron powder was filtered off and tetra sodium pyrophosphate was added to precipitate uranium pyrophosphate.  The uranous pyrophosphate precipitate in the wet state was agitated with dry caustic soda and thereafter diluted with water and filtered to remove sodium phosphate.  (3) An ore residue remaining after extraction of gold by cyanide leaching was agitated with sulphuric acid and manganese dioxide to obtain a leach liquor having a pH of 3.5 containing iron, aluminium, silica and minor amounts of uranium. The leach liquor was neutralized to pH 6.5 with calcined magnesia and the precipitate obtained after drying was mixed with sulphuric acid to a paste and baked at 250 DEG  C.  The baked mass was agitated with a small amount of water and filtered and the solution was thereafter acidified with sulphuric acid to bring its pH to 1.3 and then agitated with iron powder.  After filtration diammonium phosphate was added to obtain uranous phosphate precipitated which was reacted with dry sodium hydroxide as before to convert it to uranous hydroxide. The solution remaining after the precipitation of uranous phosphate had been filtered was neutralized with caustic soda to pH 4.5 and a uranium containing aluminium phosphate precipitate was obtained which could be redissolved in sulphuric acid and recycled.

Title: Methods of and apparatus for direct reduction of iron ores
IPC: C21B13/06
Filed: 1945-06-26
Abstract: 597,530. Reducing ores. DEHN, F. B. (Coast Reduction, Inc.). June 26, 1945, No. 16294. [Classes 51' (ii) and 55 (ii)] In the reduction of iron ore in a multiplehearth furnace in which the reducing gas is introduced at different hearth levels and moves upwardly through the descending ore, the reducing gas is heated to such a temperature that the sensible heat thereof is sufficient to supply the heat necessary not only for the reduction of the ore but also for compensating for radiation losses. As shown, the ore passes from a bin 33 through a rotary feeder 35 on to the top hearth and is rabbled inwardly and outwardly on successive hearths from the lower of which it is discharged through a conduit 40 into a waterjacketed cooler 41. The reducing-gas is supplied from the generators 37, a number of which, e.g., three, are spaced around the reduction-chamber. The generators are supplied with a fuel gas, e.g., natural gas, heated to a temperature of about 1,000‹F. and with air at a temperature of about 2,000‹F., the gases being decomposed by heating in the generators to produce a mixture principally of carbon-monoxide and hydrogen at a temperature in excess of 2,000‹F. The hot reducing gases are admitted to the three lower hearths, although it may be found desirable to hold intermediate hearths at higher temperatures than the lower ones. The spent reducing-gas passes through a duct 50 to a stack 51, having a pressure-relief 52, and is then taken to the burners of the air and gas preheaters. The rabble arms 12 are cooled by air supplied by a blower 15 through a control valve 18 and meter 19, an air-pressure relief 22 being provided. A tube 9, within the tube 8 carrying the arms 12, is connected to the air-return passages of the arms so that the heated air passes downwardly through the tube 9 and is taken by a pipe 44 to the airpre-heater 45 for supply to the generators 37. An induced air system may be used instead of a forced system, or natural gas or coke oven gas may be used for cooling the rabble arms. Some arms, e.g., the upper arms may be cooled by air and some by gas, and jets of air may be introduced into the upper hearths to ignite the reducing-gases and preheat the ore. The rabble arms 12 may have dove-tailed recesses for detachably holding the rabbles, and spacers may be inserted between some rabbles to prevent ridges from forming in the ore bed. One or more rabble arms at each hearth level may be-provided with an end scraper to prevent the accumulation of ore on the inner wall of the furnace. Specifications 240,165 and 328,240, [both in Class 51 (ii)], are referred to.
