[Class 144 (i)] Tractor and like wheels having pneumatic tyres are fitted with shoes 13 carried by side rings within which the wheel can rotate with the shoes inoperative, or which can be clutched to the wheel so as to rotate the shoes into groundengagement. In the form shown in Figs. 1 and 3, rings 9 carrying the shoes 13 are rotatably mounted on Ranged rings 5 bolted to the wheel hub 4. In the inoperative position shown, in which the lowermost pair of shoes is raised clear of the ground, the rings 9 are locked against rotation by the engagement of trip-arms 30, pivoted on a hand-lever 28, with the tails 36 of pawls 16 pivoted on the rings 9. To bring the shoes into operation, the lever 28 is moved in the direction of the arrow, Fig. 1, whereby links 32 on the lever move the pawls 16 into the paths of lugs 14 on the wheel. In the modification shown in Figs 4 and 6, the shoe-carrying rings 9a are formed with races co-operating with rollers 38 mounted on the wheel-rim so that the latter normally rotates within the rings, pawls 55 pivoted on the rings being held clear of the rollers 38 by the engagement of cranks 68 on the hand-lever 67 with trip-arms 60 on the pawls. When the lever is moved to clear the trips 60, springs 61 react to swing the pawls 55 into the paths of the rollers 38. In both modifications, the shoes are mounted so as to be clear of the tyre tread when away from the ground, the shoes shown in Figs 4 and 6 being pivoted on brackets 44 on the rings 9a and pressed radially outwards by springs 49.

Title: Improvements in or relating to the treatment of oxidised ores or other oxidised compounds of copper and zinc
IPC: C22B3/14
Filed: 1922-11-20
Abstract: 215,802. Edwards, G. W., and Durant, H. T. Nov. 20, 1922. No Patent granted (Sealing fee not paid). Ammonium compounds containing metals. - Copper and zinc are extracted from ores or products containing them in a form in which they are soluble in ammonial solutions, by treating with an ammonium salt solution containing free ammonia at a temperature a little below the point at which the ammoniacal compound dissosiates or ammonia is evolved and at atmospheric pressure. The invention is described with particular reference to the extraction of copper from oxidized or carbonate ores, but it is stated to be applicable to extracting zinc from oxidized leadzinc ores, in which case the lead remains in the residue. The ore is treated with ammonium carbonate and ammonia solution in a dissolving tank 1 having a stirrer 2 and heating coil 4, any ammonia evolved being led by a pipe 5 to a condenser 6. The solution is filtered off in a filter 7 and is led to a tank 8, the residue being received at 9 and the washings at 10. The solution from this tank 8 is led to a tank 11 in which it is heated by steam from a boiler 13 so as to drive off ammonia and precipitate the copper oxide. The vapours driven off are taken by a pipe 14 to the coil 4 for heating the tank 1 or may be led direct to the condenser 6. The liquor from the tank 11 is led to a tank 16 and thence to the filter 7 for washing the oxide. Liquor from the tank 10 and from a tank 22 which receives the condensate from the condenser 6, is taken back to the tank 1 by a pipe 18. The various transfers of liquor are effected by suitable connections with the suction and pressure pipes 20, 21 of an air pump 19. A scrubber 23 is provided for absorbing any ammonia escaping from the condenser in liquor from the tank 16. Specifications 2431/79 and 18864/00 are referred to.

Title: Process and apparatus for supplying finely-divided solid fuels to a high-pressure gasification system
IPC: C10J3/50
Filed: 1965-07-26
Abstract: Finely divided solid fuel, e.g. coal dust, is gasified under high pressure with oxygen in a gasifier to which it is delivered by the following process.  The coal is mixed with a liquid paraffin having 1 to 5 carbon atoms and the suspension is brought to the operating pressure, e.g. 25 atmospheres gauge, before being passed through a heating zone where the paraffin is evaporated. The coal and the vapour are separated in a cyclone and the coal is delivered (via a bunker and feed screw) to the gasifier with oxygen, and the vapour is condensed and the condensate recycled for mixing with fresh coal dust.  The heating zone may use wet steam as heating medium, and the condensing stage may comprise three coolers in series, namely:-a waste heat boiler, a heat exchanger (water) and an ammonia refrigeration plant.  A detailed example is described in which butane is the paraffin, and pressures and temperatures in all parts of the apparatus are given.  The butane, which is in weight proportion of 1 to 2.5 parts coal dust, is cooled to - 12 DEG  C. before mixing.

Abstract: 1,159,347. Image intensifier tubes. MULLARD Ltd. 6 June, 1968 [12 July, 1967], No. 32016/67. Heading H1D. [Also in Divisions H4 and H5] A particle or radiation quantum detector system comprises a channel intensifier device I having an output electrode in the form of a plurality of rows of conductors E2 and having a plurality of target conductors T arranged in columns, so that an input particle causes secondary electron emission in the channel portion I resulting in an output signal in an output electrode and in a target conductor according to the position of the input particle. The intensifier may but need not include a photo-cathode (not shown) and the target conductors T may be coated with luminescent material or may be coatings on a luminescent layer to give a visual output, and the device may be included in an envelope, though this is not necessary in space applications. The outputs from the rows and columns may be fed to a ferrite core store supplying a cathode ray display (Fig. 4, not shown). In Fig. 5 the outputs are fed to row and column registers connected by respective exclusive OR gates 1 and to an AND gate 3. Only when there is a single event stored in both registers is there an output from gate 3 which opens gate 4 and sets a bi-stable 6 which opens switch 7, to prevent the recording of a further event, and opens gate 8 to allow clock pulses to step the row register and also, through a divider 10, the column register. The divider 10 also synchronizes the scanning of a storage display tube to which a bright-up pulse is supplied from AND gate 9 when the stored pulses have been driven to the ends of both registers; this pulse also re-sets the bi-stable 6 which closes the switch 7 so that the system is ready to record another event. The system may be used for X-ray or gamma ray radiography.
