Abstract: 1,120,630. Dynamo-electric machines. CROMPTON PARKINSON Ltd. 7 June, 1967 [10 March, 1966], No. 10596/66. Heading H2A. An induction motor which acts to bring a shaft to a predetermined position, e.g. for sewing machines, has oppositely moving fields on either side of the stator and an asymmetrically conductive rotor. Multipolar, three-phase stator windings are connected so that the fields diverge from A and converge at B, diametrically opposite. This axis may be shifted by altering the connections. In the form shown in Fig. 2 the rotor consists of a magnetic core 20 and copper cylinder 22, both being saw-cut at 25 over an angle of about 150‹ to reduce conductivity in this region. The unslotted region moves towards B. In a modification, only the conductive cylinder rotates, the core being fixed. Instead of the slots, part of the cylinder may be of different material, eg. insulating. At high speeds, the device acts as a brake.

Patent GB-693755-A (GB)
Title: Improvements in methods of processing vulcanizable compounds
IPC: B29C48/395
Filed: 1950-05-05
Abstract: Highly or ultra accelerated vulcanizable compositions are processed by working an elastomer containing a curing agent and other ingredients together so as to disperse them thoroughly in such a way that no appreciable vulcanization takes place, then subjecting the composition to a strip or sheet forming process and immediately cooling the composition to a temperature at which no appreciable vulcanization takes place even during prolonged storage, inserting the composition into an extrusion head, and working it to complete breakdown of the elastomer so as to render the composition uniformly extrudable by the time it reaches the point of extrusion.  Preferably the elastomer and other ingredients are first mixed together and strained and the curing agent is then worked into the mixture, and extrusion controlled so that vulcanization temperature is just reached at the conclusion of extrusion.  In Examples, a mixture of crude rubber, whiting, zinc oxide, lithopone, plasticizers, softeners, oxidation retarders and either sulphur or tetramethyl thiuram disulphide is compounded in a Banbury mixer and after straining the ingredient omitted from the first mix added and the whole mass extruded, it is vulcanized immediately.

Patent GB-114836-A (GB)
IPC: G05D13/00
Abstract: 114,836. Fulpius, E. March 31, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Centrifugal governors; fluid relays.-A governor for hydraulic motors, such as turbines, comprises a centrifugal weight 5 slidably mounted in a chamber 2 in a pulley 1 and attached to a valve 7, which normally cuts off one end of a servo-motor cylinder 19 from the liquid pressure and exhaust passages 13, 14 in the trunnion of the pulley. The centrifugal movement of the weight 5 is resisted by pressure liquid admitted to the outer end of the chamber 2 by a passage 16 and pipe 21 from a chamber 22. The chamber 22 is supplied from the pressure main 17 and the liquid escapes from it past a throttle valve 25 attached to a piston 26. This piston is pressed down by a spring 33 enclosed between it and another piston 27 adjustably connected to a lever 29, which is connected to the piston 20 of the servo-motor and actuates the sluices of the turbine through the spindle 29<1>. The action of the governor may be adjusted by means of the baffle 23 in the pipe 17 and the handwheel 30<3> and screwed spindles 30<2> of the piston 27. The action of the piston 20 on the pistons 27, 26 may be varied by moving the nut 31 relatively to the fulcrum 29' of the lever. The piston 27 is exposed to the same liquid pressure as the piston 26 by means of the pipe 34. In the form shown in Fig. 2, the centrifugal weights 1<5> act through levers 1<6> on valves 5<1>, 5<2>, which rotate with the governor and control liquid pressure and exhaust passages 17<1> and 18. Normally, the valves close these passages and the piston 20 is stationary, but when, owing to an increase of speed, the weights 1<5> move the valves to the left, pressure liquid passes from the main 17 to both sides of the piston 20 by the passages 17<1>, 19<1>, and, by differential action, moves the piston 20 to the left. The piston actuates a lever 29, which operates the turbine sluices and moves a valve-rod 25 controlling passages 26<1>, 26<2> in a piston 26, so that the inlet passage for pressure liquid from a pipe 17<2> is opened, and the liquid enters the chamber and moves the piston 26 against a spring 33, thereby returning the valves 5<1>, 5<2> to normal position. A decrease in speed moves the valves to the right and connects the right-hand end of the cylinder 19 to the exhaust pipe 18, so that the piston 20 moves to the right and opens the passage 26<2>, thereby connecting the chamber to the exhaust pipe 24 and allowing the spring 33 to move the piston 26 to the left. In a third form, a piston is mounted on the rod carrying the valves 5<1>, 5<2> and is exposed on the outer face to the liquid pressure in a chamber between two pistons connected by a tensioned spring. The valves control the pipes leading to the two ends of the cylinder 19, and the pipe 17 communicates with the space between the valves.

Abstract: 695,191. Gasifying solid carbonaceous materials. GAS RESEARCH BOARD, and DENT, F. J. June 27, 1949 [April 30, 1947], No. 11578/47. Class 55(i) In a fluidized process for the gasification of particulate solid carbonaceous fuels such as coal by means of steam and oxygen the particulate fuel is passed in succession through a series of zones so that it is preheated and subjected to a preliminary gasification in the absence of oxygen by means of hot gases from one or more subsequent zones in which it is subjected to gasification with steam and oxygen, and the fine particles of fuel entrained with the gases leaving the first zone are separated therefrom and gasified in at least a portion of the steam and oxygen to be used in the process, which steam and oxygen is then after separation of any residual ash introduced into the last of the gasification zones. In apparatus described three zones 1, 2 and 3 are provided and particulate fuel is fed into the zone 1 through a conduit 4, subsequently descending by conduits 15 and 17 into zones 2 and 3. Gaseous products leave by a line 6 and are treated in a cyclone separator 7, the separated fines being gasified by means of steam and oxygen supplied through lines 9 and 10 respectively, the mixture passing through a cyclone separator 11 for removal of residual ash before entering the zone 3. Additional steam is supplied through a line 18 and additional oxygen may be passed in through line 19. The process may be operated at atmospheric pressure or at pressures up to 50 at atmospheres and zones 2 and 3 may be maintained at temperatures of 800-900‹C and 1000-1100‹C respectively. Air or pure oxygen may be used and the residual ash may be separated by a cyclone separator from the gases rising from the zones 2 and 3 before they pass to the zone 1. Alternatively the zone 3 may be operated at a temperature, for example, above 1200‹C so that the residual ash melts and can be run off in the form of a slag. Specification 360,618 is referred to.
Patent GB-712907-A (GB)
Title: Improvements in the production of gases rich in sulphur dioxide suitable for working up into sulphuric acid
IPC: C22B1/10
Filed: 1951-05-18
Abstract: Liquids containing free or combined sulphuric acid are decomposed with the production of sulphur dioxide by introducing them into a fluidized bed consisting predominantly of substantially roasted iron pyrites through which oxygen-containing gases are passed upwardly. Iron pyrites is supplied to the bed and corresponding amounts of roasted material are withdrawn, the excess heat of roasting serving at least partly to carry out the endothermic decomposition of the liquids whereby, if necessary, with the co-employment of additional measures, the temperature is maintained below the softening point of the roasted material, e.g. 800 to 1100 DEG  C.  The liquids may be waste sulphuric acid which may contain resins, resulting from the purification of hydrocarbons with sulphuric acid, waste liquors containing sulphates such as pickling liquors or denitrated waste acids from nitration processes.  The roasted ore dust, which may contain iron sulphate due to the presence of sulphur trioxide, may be returned to the bed.  Sulphur minerals containing iron and zinc in sulphidic form, e.g. 75 per cent. FeS2, 11 per cent.  ZnS may be roasted, employing temperatures of 1000 to 1100 DEG  C.  The sulphur dioxide-containing roaster gases having a temperature of about 870 DEG  C. may be passed through a steam boiler and cooled to 250 DEG C., passed through cyclone separators or electrical purifiers to remove dust, and cooled by indirect air cooling or direct water cooling, the water being withdrawn as hot as possible, e.g. 90 DEG C.  The acid mist which forms on cooling is separated by the electrostatic separators.  The moist gases, rich in sulphur dioxide, may then be used for the production of aqueous sulphurous acid or sulphites or worked up by known means to pure sulphur dioxide.  The roaster gases may also be used to produce sulphuric acid by the chamber or the wet catalysis process. Thus, in the production of sulphuric acid and oleum, the roaster gases are dried with sulphuric acid, which acid is then employed to dry the air to be added, thereby removing dissolved sulphur dioxide from the acid, which is then reconcentrated.  According to an example, to a fluidized bed which in quiescence is 55 centimetres deep, 1250 kilos of iron pyrites (sulphur content 48 per cent.) having a grain size up to 4 mm., are introduced per hour per square metre of bed cross-sectional area. Into an expansion zone 65 cms. high, above the bed, 606 kilos of sulphuric acid (96 per cent. H2 SO4) are sprayed per hour per square metre.  A temperature of 890 to 910 DEG  C. is maintained and the roaster gas has a SO2 content of 20.6 per cent. and is practically free from oxygen; its SO3 content is about 4 grams per cubic metre. Specifications 712,899 and 712,906 are referred to.
