Title: An Improved Process for Distilling Metallic Ores and other Materials containing Metals.
Inventor: JONES DAVID BENTON
IPC: C22B19/04
Filed: 1917-08-10
Abstract: 112,924. Jones, D. B., (Assignee of Fulton, C. H. and Bains, T. M.). Jan. 24, 1917, [Convention date]. Electrode f urnaces. - 0 r e or other materials containing zinc, antimony, bismuth, mercury, or other metal are formed into briquettes that will retain substantially their original form and volume while being distilled by a continuous process, and such briquettes are fed through the distillation chamber of an electric furnace. Fig. 1 shows a suitable furnace, partly in vertical section. The distillation chamber is enclosed by two concentric annular walls A, A<1> and divided by partitions 2, Fig. 3, into six smaller chambers through each of which two columns x of briquettes are fed upwards by means of a reciprocating table 9. During the feeding operation, the table supports and pushes upwards the two columns of briquettes and, at the end of the feed, the new briquette is clamped between a fixed piece 13 and a movable one 14, which is secured by bolt and nut 15; before a feeding operation, the piece 14 is released. The distillation of the briquettes is effected by passing a current through each column of briquettes by any suitable means, but the furnace may be designed for use with a three-phase connexion of the Y-type, in which case, three of the lower electrodes 8<a> will be connected to a neutral conductor, and the other three to supply conductors, and the upper electrodes 8 will be conrected in adjacent pairs. Good contact between the electrodes and briquettes may be obtained by making the holes in the electrodes slightly tapered or of conical form and filling the spaces between the sides of the holes and the briquettes with granular conducting-material, e.g. graphite; this may be introduced, for the lower electrodes, through passages 17 in the outer walls of the furnace. The zinc &c. fumes pass from the distilling chambers through passages 4 and in zigzag course along a series of concentric condenser chambers formed by a series of concentric walls 3, and the condensed metal flows away through a passage 7 in the floor 6 of the condenser; any reduced metal collecting in the lower part of the distilling chambers flows into the condenser through openings 4<a>. just above the lower electrodes. Before being fed into the briquette columns. the briquettes are preheated and are next baked to make them good conductors. The baking may be effected in the annular chamber E beneath the lower electrodes. the evolved gases being conducted through passages 19 into annular cooling chambers above the upper electrodes.

Abstract: 559,181. Thermocouplers; glass/metal seals. GRAVES, A., ALLTOOLS, Ltd., TOMES, G. A. R., and CINEMA-TELEVISION, Ltd. Aug. 19, 1942, No. 11681. [Classes 36 and 53] [Also in Groups XL and XXIII] A static vacuum thermocouple comprises a highly-evacuated vessel 10 formed with an aperture, a thermocouple 36 mounted in the vessel with its hot junction opposite the aperture, and a window 12 consisting of a thin film of approximately soap-bubble thickness of a vitreous material such as ordinary glass, high silicate glass, or fused quartz; the window being fused or welded at its edges to the material of the vessel at the boundaries of the aperture. The window material is first blown into a bubble. The rim of the aperture of a glass vessel is then softened with the aid of a blow pipe and the softened rim brought into contact with the bubble. This causes a small piece of the bubble to become attached to the rim. In a modified process, a piece of the bubble is picked up between the aperture and the end of a glass tube of the same diameter. Heat is then applied round the junction to fuse the parts together, and after this the tube is cut short near the window. The vessel may be made of a metal such as copper, multiple seals being then used to weld the window to the vessel. The window may be reinforced on the outside or the inside. A mask 25 may be inserted between the thermocouple and the window and may support the window. The vessel may be double walled or enclosed in an outer casing, the outer wall or casing being provided with a window 28 opposite the thin window of the inner wall or casing. The thermocouple may be as described in Specifications 559,182 and 559,183.

Regenerated collagen fibres are made by extruding a collagen solution into a spinning bath comprising a solution of an ammonium or monovalent metal inorganic or organic salt adjusted to pH 8-12, stretching the collagen fibres formed, and cross-linking the collagen molecules with a poly-functional organic compound capable of improving their resistance to shrinkage in water. The collagen fibres may be stretched in a second bath differing in composition from the spinning bath. Such a bath may have a salt concentration of 15-30 % by weight and pH 3À5-5À5 or a salt concentration of 8-15% by weight and pH 10-12À5. Cross-linking may be effected by impregnating the fibres with a solution, adjusted to pH 4À5-10, of di- or trimethylol melamine, di- or tri-methylol urea or dimethylol ethylene urea, and heating to 50- 70‹ C. A hardening catalyst may be present in the solution and after gradually raising the temperature to 50-70‹ C., the fibres may be then heated at 80-150‹ C. for 5-30 minutes. The fibres may also be impregnated with a solution containing 0À01-2À0% by weight formaldehyde, adjusted to pH 7À0-11À0, 0À1-3À0% by weight of a non-ionic or cationic surface-active agent and more than 5% by weight of an inorganic or organic salt, and submitted to a temperature of 15-50‹ C. After impregnation the fibres may be squeezed until they retain 70-200% of their original weight of impregnating solution and then heated gradually.

Filed: 1918-07-18
Abstract: 122,364. Craig, R. C., and Bedgood, H. O. July 18, 1918. Steam traps.-Relates to drain traps for steam or compressed air of the type in which the main drain valve is operated by the steam or air pressure under the control of a piston pilot valve operated by a bucket float. The water of condensation is guided by lips n<1> into the space surrounding the float d. When the water overflows into the float d, the float descends quickly by reason of the large volume of water in the enlarged annular part c<1> of the chamber. The fall of the float allows steam or air to pass through the passages i, i<1> in the two-part piston control valve k<1>, k<2> to the piston h<1>, whereupon the drain valve h is opened. The water in the float is then forced out through a dip-pipe communicating with the valve chamber f. The valves are carried in a cover part b of the trap part a.

Title: Improvements in or relating to gas turbine engines
Inventor: THORN JAMES DOUGLAS
IPC: F02C3/20
Filed: 1954-04-24
Abstract: 781,429. Gas turbine plant. RUSTON & HORNSBY, Ltd. April 25, 1955 [April 24, 1954], No. 11885/54. Class 110 (3). [Also in Groups XXIX and XXXV] A two-stage arrangement for the supply of fluidized fuel to the combustion chamber of a gas turbine engine comprising two fluidizing columns in series, the first working at atmospheric pressure and the second at a pressure appropriate to the feeding of the fluidized fuel into the combustion chamber has the fluidized fuel supply from the atmospheric column to the pressurized column controlled in accordance with the level of the fluidized fuel in the pressurized column. From the atmospheric fluidizing column 22 which acts as a storage vessel the fuel is pumped by means of a peat pump 23 and a high-pressure air supply 24 through a conduit 25 to a small cyclone 26 arranged on top of a pressurized fluidizing column 27 which separates the high-pressure air from the peat. The level of fluidized fuel in the pressurized column 27 is maintained between lower and upper limits determined by probes 40, 41. These probes are connected to a double-acting relay 42 operating a solenoid-actuated valve 61. When the level of the fuel reaches the upper probe 41, the relay 42 is actuated to open its contacts and thus open the valve 61. These contacts remain open until the level falls below the lower probe 40. The flow of fuel from the atmospheric column 22 to the pressurized column is controlled by a three-position valve 43 consisting of a valve member 45 connected to an operating piston 44 subject permanently to the oil pressure in a line 48. At three different heights in the cylinder wall are drain connections 49, 50, 51. If the solenoid valve 52 controlling the drain connection 49 is open, the piston 44 will be in its uppermost position and the fuel supply cut off. If the valve 52 is closed and valve 61 controlled by the probes 40, 41 open, the piston will be stopped at an intermediate position in which a small aperture 54 in the valve member 45 permits a restricted flow of fuel. If both valves 52 and 61 are closed the piston moves to its lowermost position and a large aperture 55 permits a full flow of fuel. In a modification the pressure drop of the fluidizing air in its passage through the fuel bed of the pressurized column is used to control the outlet valve of the atmospheric column. Specifications 781,427, 781,428, 781,430 and 781,431 are referred to.

Abstract: 781,431. Gas turbine plant. RUSTON & HORNSBY, Ltd. April 25, 1955 [April 24, 1954], No. 11887/54. Class 110 (3). A two-stage arrangement for the supply of fluidized fuel to the combustion chamber of a gas turbine engine comprising two fluidizing columns in series, the first working at atmospheric pressure and the second at a pressure appropriate to the feeding of the fluidized fuel into the combustion chamber has the fluidizing air supplied to the pressurized column taken from the duct between the compressor and combustion chamber of the engine. Peat from a de-watering press (not shown) is fed to a disintegrator 11, Fig. 1, and then passed to a rotary louvre drier 12 where it is dried by the gas turbine engine exhaust fed through a conduit 13. The peat leaving the drier 12 falls on to a rotary table 15 where it is divided into two parts, one part being led to the mix back conveyer 16 and returned to the de-watering press and the other to the conduit 17 leading to the air-swept grinding machine 19. The relative sizes of the two parts is controlled by the position of the adjustable blades 18. On leaving the grinding machine the pulverized fuel is separated from the carrying air in a cyclone 21 arranged on top of an atmospheric fluidizing column 22 which acts as a storage vessel. From the column 22 the fuel is pumped by means of a peat pump 23 and a high-pressure air supply 24 through a conduit 25 to a small cyclone 26, arranged on top of a pressurized fluidizing column 27, which separates the high-pressure air from the peat. From the column 27 the peat is delivered from a valve 28 and conduit 29 to the combustion chamber 30 of the gas turbine plant. The high-pressure air from the cyclone 26 is led through the conduit 32 to the combustion chamber. The fluidizing air for the column 27 is taken from the gas turbine compressor 34 through a booster fan 35 and conduit 36. The control valve 28 is controlled by an engine speed responsive governor 38 through an oil pressure line 38. To avoid velocity variations in the supply of fluidizing air to the pressurized column 27 a self-regulating throttle valve 62 is arranged in the conduit 61<SP>1</SP> upstream of a venturi 63. The pressures at the throat and downstream of the venturi actuate a diaphragm 66 controlling through a valve 67 the throttle valve 62.
