IPC: C02F3/12
Filed: 1996-08-06
Abstract: PCT No. PCT/NO95/00027 Sec. 371 Date Sep. 26, 1996 Sec. 102(e) Date Sep. 26, 1996 PCT Filed Feb. 6, 1995 PCT Pub. No. WO95/21134 PCT Pub. Date Aug. 10, 1995Water to be treated is introduced into a basin having a closed bottom and an outer wall. A stationary diffusor is located at the bottom at a position spaced from the outer wall and produces air bubbles of varying size acting to lift water impurities toward the surface of the water and to circulate the water in the basin as a first stream flowing vertically upwardly from the diffusor, horizontally outwardly toward the outer wall, vertically downwardly toward the bottom and horizontally along the bottom back to the diffusor. A second stream is caused to circulate circumferentially in the basin. The first and second circulating streams cooperate to cause foam and slurry formed on the surface to concentrate in an outer peripheral flow path from which the foam and slurry are removed.

Inventor: HILTUNEN JYRKI
IPC: B01J8/18
Filed: 1998-02-27
Abstract: The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention, the feedstock is fed into a fluidized-bed reactor, wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor and the regenerator comprise risers having an axially annular cross section and being equipped with multi-inlet cyclones for the separation of particulate matter. By means of the invention, it is possible to producer pyrolysis oil, the quality of which is higher than that of oil produced with the processes of the prior art. The incorporation of multi-inlet cyclones into the reactor configuration reduces gas velocities, reduces the physical size of the cyclone and shortens the residence time of gases in the cyclone.

Filed: 1941-02-06
Abstract: 546,977. Artificial filaments &c. ; casein. COURTAULDS, Ltd., and PENN, W. Feb. 6, 1941, No. 1578. [Classes 2 (ii) and 2 (iii)] Artificial filaments or fibres of animal or vegetable casein are hardened by treatment with a solution of a beryllium salt and with an aldehyde. Soluble basic salts of beryllium are preferred. Treatment with aldehyde may take place before, after, or at the same time as the treatment with a beryllium salt. The filaments or fibres may be subjected also to other hardening processes, e.g. to treatment with an aluminium salt with or without formaldehyde. In an example, beryllium sulphate is dissolved in water; formaldehyde is added, and then beryllium carbonate is stirred into the solution. When solution has taken place, a skein of casein fibres, already hardened with aluminium sulphate and formaldehyde, is immersed in the solution which is then heated for several hours at 75‹C. The skein is washed and dried. The fibre has a reduced wet extensibility and is less plastic in hot water than the untreated fibre.

Filed: 1961-01-17
Abstract: 920,982. Consuming noxious vapours. W. C. HOLMES & CO. Ltd. Jan. 8, 1962 [Jan. 17, 1961], No. 1869/61. Class 51 (1). [Also in Group XXVIII] Gases given off from an electric arc furnace, particularly during the production of steel, are fed to a combustion chamber and completely burned to eliminate carbon monoxide. Gases from the furnace are drawn off through an inlet 2 maintained at a slight vacuum by a stack 3 beyond the gas cleaning equipment, which may have a fan 13. Gases are partly burned within pipes 2 and 6, with air admitted through a slip joint 5, and combustion is completed in a chamber 7, with additional air from a dampened inlet 8. Ignition burners 24 may be arranged at the entrance to the combustion chamber 7. The gases from the chamber 7, after passing baffles 25, are cooled by water sprays in an adjacent chamber 9, and fed to a wet precipitator 20. Sludge from the cooling chamber 9 and the precipitator 20 is fed to a settling tank, and the water recirculated. The water supply to the cooling chamber 9 is controlled in accordance with the temperatures at the outlet of the chamber 9 and the entry to the precipitator 20, and the pressure at the outlet 2 from the furnace roof controls a water-cooled damper 4. The pressure control may have two positions, so that different conditions during the oxygen blowing and refining periods of a steel making furnace. During melting down of oily scrap, appreciable amounts of hydrogen may be given, which is burnt in the chamber 7. A slight pressure in the furnace during the refining period may be obtained by closing the damper 4, or an additional damper may be arranged downstream of the cooling chamber 9. According to the Provisional Specification, the wet precipitator may be replaced by an electrostatic precipitator or by filters.

Title: Improvements in or relating to fluid-pressure apparatus for controlling the operation of brakes for aircraft
IPC: B64C25/48
Filed: 1939-01-19
Abstract: 525,266. Brakes for aircraft. DUNLOP RUBBER CO., Ltd., BEHARRELL, G. E., WRIGHT, J., and TREVASKIS, H. Jan. 19, 1939, No. 1874. Addition to 507,162. [Class 4] [Also in Group XXXIV] The fluid-pressure brake operating mechanism described in the parent Specification is modified particularly for the use of compressed air as the operating fluid. The modifications concern in particular the exhaust valve 21, sealing means for the spring-loaded sleeve 24 which is provided with the exhaust port and sealing means for the rod 20, by which the floating-lever is operated. The pair of valves for the brakes on the side of the aircraft is shown. Upward movement of the rod 20 first causes the floating- lever 15 to fulcrum on the rod 14 of the supply valve 5 to slide the plug 21 in the sleeve 24 so as to seat the exhaust valve member 22 on the exhaust port 23 provided on the sleeve and subsequently to lift the valve 5, thus supplying the brake by way of chambers 8, 10, and passage 12. If the rod 20 is held, the brake pressure in chamber 10 acting on the plug 21 and sleeve 24 depresses these against the resistance of the spring 25 and so permits the valve 5 to close, the brake pressure being thus dependent upon the extent of movement of the rod 20. Return movement of the rod 20 unseats the valve 22 as shown and the compressed air from the brake exhausts through the passage 12 channels 32 in the plug 21 and the port 23. The supply valve rod 14 bears on a member 16 pivoted to the lever 15 and slidable in the casing. A screwed plug 17 serves to adjust this member and the valve 5. Leakage from the chamber 10 past the sleeve 24 is prevented by a rubber sleeve 30 attached at its lower part to the casing by a bush 31 and an extension of the screwed cap 26. To prevent leakage from chamber 10 past the rod 20, while permitting tilting of the rod, a spring 37 is secured at its ends respectively to the upper part of the rod and to a disc 38 and a rubber sleeve 39 is fitted over the spring and a flange on the sleeve is clamped between a cap 41 and a sleeve 40. A baffle in the passage between the main pressure supply pipe and the supply valve chamber 8 prevents pressure building up too rapidly in chamber 10. Mechanism for effecting differential control of the brakes on opposite sides of the aircraft is described and is substantially the same as that described in the parent Specification.
