Abstract: 573,000. Endless-belt conveyers. HEWLETT, R. June 12, 1943, No. 9500. [Class 78 (i)] Means for returning to the upper run 20 of a conveyer belt coal &c., spilt on to the lower run 21 and brought round between the end roller 22 and the belt comprises a tray 23 located closely under the upper run so as to receive the spilt coal from the roller, together with means for deflecting the coal deposited on the tray towards one or both sides of the belt, and further means for directing the coal on to the upper surface of the belt. The tray is formed with corrugations 41 inclined at an angle to the sides of the conveyer, so that the movement of the belt over the tray causes the coal trapped between the belt and the tray to move out to the sides and against flanges 27 on the tray. Ploughs 28 are pivoted to the tray on vertical and horizontal pivots 29, 30 and direct the deflected coal on to the top of the upper run 20 of the belt. Arms 34, shaped as shown in the drawings, are pivoted to the tray and their free ends are drawn towards the sides of the belt by a spring 35; any coal that escapes the plough is directed by the arms on to the top of the belt. The ploughs can swing freely between stops formed by gaps in the side flanges 27 of the tray. Coal on the lower run 21 of the belt is deflected away from the centre towards the sides by a fixed plough 40, and any coal brought over the centre of the end roller 22 falls through a central hole 32 in the tray and is diverted by a member 37 on to one or other side of the lower run 21 so that it is now brought up towards one or other end of the roller. In a modification, Fig. 17 (not shown), an auxiliary conveyer belt or belts is or are provided instead of the ploughs 28. These auxiliary belts are disposed at the sides of the tray and slope upwardly so as to raise coal from the tray slightly above the level of the upper run 20, this coal being then delivered on to the main conveyer by stationary ploughs.

Abstract: A process for hydrofluorinating acetylenic hydrocarbons comprises contacting a gaseous mixture of hydrofluoric acid and at least one acetylenic hydrocarbon with a catalyst which comprises one or more mercury derivatives laid on a carrier of porous sintered alumina. The gaseous mixture contains 0.8 to 2 moles of hydrofluoric acid per mole of acetylenic hydrocarbon and the porous sintered alumina has a total porosity of between 5 and 50 cm.3 per 100 g. of alumina and a specific surface area of between 0.01 m2/g. and 1 m2/g.  The reaction is conducted at a temperature of from 25 DEG  to 150 DEG  C. and a pressure of 0.2 atm. to 10 atm. A gaseous oxygenous derivative of nitrogen may be added to the acetylenic hydrocarbon or to the gaseous mixture specified above.  Examples describe the conversion of acetylene to vinyl fluoride, 1,1-difluoroethane being formed in minor amounts.ALSO:A catalyst for the hydrofluorination of acetylenes comprises one or more mercury derivatives laid on a carrier formed of a porous sintered alumina with a total porosity of between 5 and 50 cm3/100g. of alumina and a specific surface area of between 0.01 and 1 m2/g.  The alumina may have various forms, for example granules, fragments, balls and pellets.  The catalysts may be prepared by impregnating sintered alumina with a solution of a mercury derivative and then drying the impregnated product. Before conducting the hydrofluorination reaction a gaseous current of anhydrous hydrogen fluoride, which may be diluted with a gas which is inert to the hydrogen fluoride and to the catalyst, may be passed through a bed of the catalyst at a temperature above 20 DEG C.  Examples describe catalysts in which the mercury derivative is mercuric nitrate.

Title: Means for limiting the supply of fuel to continuous combustion turbine engines during accelerations of the latter
Inventor: CAREY FREDERICK HENRY
IPC: F02C9/16
Filed: 1950-04-19
Abstract: 695,020. Gas turbine plant. DOWTY EQUIPMENT, Ltd. April 17, 1951 [April 19, 1950], No. 9654/50. Class 110(iii) [Also in Group XXIX] In a liquid fuel supply system for aircraft gas turbine engines, the fuel supply is controlled by a servomotor 11f which when the fuel supply exceeds a predetermined maximum value during periods of acceleration is operated on by a vent valve 19 which is subject to opposed loadings one of which is a measure of the rate of fuel supply to the burners and tends to move the vent valve in the opening direction and the other of which includes spring means 20, reacting between the vent valve and an abutment constituted by a three-dimensional cam 22 of calculated configuration which moves in one of two operative directions to vary the variable loading in accordance with changes in air intake pressure and in the other operative direction to vary the variable loading in accordance with changes in engine speed. As shown, the cam 22 is adapted to be moved axially by an evacuated capsule 30 responsive to changes in air intake pressure through an inlet 32 and to be rotated by a rack and pinion mechanism 25 whereof the rack is operated by an evacuated capsule 26 connected by a pipe 28a to the delivery of the engine-driven compressor 10a and therefore responsive to changes in engine speed. The capsule 30 is exposed to air intake pressure through the nozzle 32b and is therefore responsive also to changes in the forward speed of the aircraft. The cam 22 acts through a plunger 21 on a spring 20 loading the vent valve 19 towards its closed position. The spindle 16 of the vent valve carries a piston 17 exposed on its under side to the delivery pressure of the fuel pump 11 which supplies the burners 14 from a tank 12. The servomotor piston 11f carries a fuel by-pass valve 11b and is normally controlled by one or more vent valves such as the governor valve 15b. The vent valve 19 is operative to override the valve or valves 15b when the fuel supply exceeds a predetermined limit determined by the cam 22. Alternatively, the servomotor may control the stroke varying element of a variable delivery pump, or a throttle in the delivery line of a centrifugal fuel pump.

Title: Improvements in the bessemerizing of nickel containing matters
IPC: C22B15/00
Filed: 1930-03-28
Abstract: Nickel-containing mattes are Bessemerized by a blast of previously superheated steam alone or in admixture with a small proportion of air.  This may be followed by raising the temperature of the bath and blowing with superheated steam alone to eliminate practically all the sulphur.  The matte is charged into a converter in lump or ground form, melted preferably by the aid of gas blast burners till the temperature reaches 2400-2700 DEG  F. when it contains about 18 per cent of sulphur.  The steam, or mixture of steam with preferably 10 per cent of air, is blown with the converter tilted into the blow position, the temperature of the bath being maintained at 2700-2900 DEG  F. by means of the gas burners, until the sulphur is reduced to 2-4 per cent.  In the next stage the temperature of the bath is raised to 2700-2900 DEG  F. and superheated steam alone blown in, the sulphur being reduced to 0,005-,02 per cent.  Oxygen may be removed at the end by means of a reducing flame, carbon or any suitable deoxidizer such as magnesium, manganese, silicon, calcium or boron, or by poling, in the converter or any suitable receptacle.  The temperature of the superheated steam should be 800-1200 DEG  F. and the process may be carried out in a suitably designed arc, resistor or induction furnace provided with tuyeres.  Specification 271,282, [Class 82 (i), Metals, Extracting &c.], is referred to.

Abstract: 1381456 Seaming non-metallic sheet material SEMPERIT AG 1 March 1973 [8 March 1972] 9917/73 Heading B5K A butt joint is formed between respective ends of two lengths of hollow-section strip of rubber or other elastic material by introducing a single- or multipiece core 10 which fills the internal cross-section of the strip into the strip lengths at the ends to be joined, bringing the end faces of the lengths to be joined into abutting relationship on the core 10, joining together the abutting end faces, removing the core 10 through an opening 11 made in the strip adjacent to the joint, and finally closing the opening 11. As shown in Fig. 1, the hollow strip comprises four walls 1, 2, 3, 4, the walls 3, 4 being depressed inwardly to form grooves 3<SP>1</SP>, 4<SP>1</SP>. The walls 1, 2 are reinforced by curved walls 5, 6 with the hollows formed thereby filled with foam rubber 7. The lengths to be joined are assembled so that half of the core length extends into each strip length. Joining is effected by vulcanizing or glueing, e.g. by using a mixture which produces hot or cold vulcanizing. A longitudinal slit 11 is produced in one strip length, preferably, having a length substantially equal to half that of the maximum periphery of the core 10 and the distance between the slit and the butt joint being substantially equal to half the overall length of the core. As shown in Fig. 2, the core 10 has a tapered end portion 12 terminating in an eye 13 into which a hooking tool 14 is inserted to withdraw the core 10 through the slit 11. The end faces of the strip lengths to be joined may have mating profiles, e.g. they may be chamfered or serrated. In a modification (not shown), the interior of the strip is divided into a number of separate cavities and each cavity is provided with its own core section during joining.
