Title: Method and apparatus for preventing overloading in centrifugal separators
Inventor: WILSMANN WILHELM
IPC: B04B1/08
Filed: 1964-11-30
Abstract: 1,030,938. Centrifugal separators. WESTFALIA SEPARATOR A.G. Nov. 30, 1964 No. 48658/64. Heading B2P. Drum overloading occurring in a centrifugal separator as a result of the build up of a heavy component deposited on the inner wall of the separator drum is prevented by interrupting the supply to the separating chamber of the untreated material when the depth of the heavy component deposited reaches a predetermined value and diverting the untreated material into a drum overflow system. The material to be centrifuged, e.g. a mercury-liquid mixture, is introduced into the separator drum through a pipe 1 and passes from a feed chamber via passages 3, 4 into the separating chamber. The passages 4 are formed by a bottom plate 6 projecting beyond the outer edge of the stack of plates 5 in the chamber. During centrifuging the heavier component is deposited on the wall 7 and the liquid component or components is/are discharged through outlet 8 or outlets 8, 9. As soon as the heavier component has reached the depth 10 and covered the exit apertures of the passages 4, the entry of further untreated material into the separating chamber is preventing so that it flows through the drum overflow passage 11. A device sensitive to the flow of material may be incorporated in the discharge pipe leading from the overflow passage 11 to indicate to the operator that the depth 10 has been reached. The device may also be used to initiate removal of the heavier component from the drum. Alternatively, the device may be incorporated in one of the two discharge systems for the lighter liquid components and responds when the flow of liquid ceases.

Title: Wide band and color cathode ray tubes and systems
IPC: H04N9/24
Filed: 1962-12-28
Abstract: 1,035,026. Colour television tubes. D. M. GOODMAN. Dec. 28, 1962, No. 48875/62. Heading H1D. [Also in Division H4] In a colour television display tube of the beam-indexing type, the cross-section of the electron beam is elongated in proportion to the intensity of the colour signal to be displayed. The display screen may comprise a repeating sequence of red-green-blue-green phosphor strips 40-43, Fig. 2A, light reflecting aluminium layer 30 and indexing strips 36, 38. Strips 36 may be of HexZnO, Ba 2 SiO 4  activated by Pb, or triclinic CaMgSiO 4  activated by Ce, to produce U.V. light, while strips 38 are of W or Mo to generate X-rays. Alternatively, strips 36 may also generate X-rays, use being made of the characteristic radiations of Mo and Cu to produce distinguishable signals. Strips 36, 38 may be connected by transverse wires to form a grid operated at high voltage. Index pulses produced by strips 36 may be fed to gates 76, 78, Fig. 10, after suitable time delays to control application of the red and green video signals to the control grid 100 of the cathode-ray tube gun. These signals are also fed to beamshaping plates 20 to elongate the beam in a direction parallel to the phosphor strips. Signals may also be fed to plates 22 to control the spread of the beam or to control the linescanning velocity. Video signals may also control the duration of excitation of each colour strip as claimed in Specification 1,035,029. The indexing strips may be replaced by a copper layer 32, Fig. 3A, providing continuous X-radiation and operated at a voltage different from that of a transparent, conductive grid or coating 45 on the viewing side of the screen, indexing signals being produced at 44a, 44b, and 44c as changes in X-radiation, or electromagnetic signals in the Hertzian or microwave range. A screen comprising a single set of indexing strips, one for each sequence of equi-width red-blue-green phosphor strips, is also described. To make effective use of the screen area while still achieving colour purity, the arrangement of phosphor strips may alternatively be chosen so that the proportion of each colour strip excited by the electron beam is reduced in the direction of scan for each sequence dependent on one indexing pulse. The indexing signals may be detected by one or more photo-multipliers arranged outside and/or inside the tube envelope. In the latter case, for example, U.V. light and X-radiation may be received by light pipes 350, 352, Fig. 15 (not shown) of nickel oxide glass, and fused silica coated with zinc oxide, respectively, which are associated with photo-cathodes 360, 362 and dynodes 364-368. If only one kind of radiation is being detected, a single, larger light pipe, apertured to pass the electron beam, is used. Alternatively, the electro-magnetic indexing radiation may be picked up and transmitted to a photo-multiplier by lenses, hollow or solid pipes or cones, or in the case of radio waves by coaxial transmission lines, fixed to or around the electron gun of the tube.

Title: Tin recovery
IPC: C22B25/00
Filed: 1965-11-23
Abstract: Tin is recovered from an aqueous solution containing a tin salt and an iron salt of hydrochloric or sulphuric acid by contacting the solution with activated carbon, thereby selectively absorbing the tin salt, and eluting the tin salt from activated carbon with an aqueous solution of NaOH (e.g. 2 to 4 N) thereby forming a solution of sodium stannate in NaOH.  The tin may be recovered from the sodium stannate solution by electrodeposition.  The starting solution for the above process may be obtained by leaching, preferably with dilute HCl, a tin-containing substance, particularly a tin-oxide-containing mining slime, containing less than 10% by weight of tin to form a solution of SnCl4 in HCl.  Preferably the concentration of the HCl is 5 to 7% by weight and the mole ratio of HCl:Sn is at least 20.  The leaching may be carried out at 60-105 DEG  C. for 15-30 minutes.

Filed: 1971-10-26
Abstract: 1351823 Removal of sulphur oxides from flue gas COMBUSTION ENG Inc 26 Oct 1971 [27 Oct 1970] 49708/71 Heading C1A In a system for removing sulphur oxides from flue gas by means of wet-scrubbing process, the reactant to be introduced into said scrubber is prepared by: (a) feeding said reactant in the solid state to an entrainment chamber; (b) passing a portion of said flue gas into the entrainment chamber to entrain the reactant in the gas stream; (c) passing the gas containing the entrained reactant to a slurry tank containing water; (d) passing the thus formed slurry to the wet scrubber for reaction with the sulphur oxides in the flue gas; (e) conducting the gas liberated in the formation of the slurry to the scrubber. The reactant may be pulverized if desired in the entrainment chamber, and its moisture content may be controlled by varying the temperature and/or the flow rate of the gas passed into the entrainment chamber. When the reactant is pulverized in a gas-swept pulverizing mill the flow rate of hot flue gas to the pulverizing mill may be varied to control the heat input and at the same time the dryness of the reactant. The Figure schematically shows a suitable plant in which the process may be carried out. Gas from a fossil fuel fired furnace 10 is passed via conduit 12 and heater 16 to a scrubber 18 containing one or several marble beds 20 on to which is sprayed a watery slurry of a reactant such as dolomite or limestone. The slurry and reaction products fall into the tank portion 24 from which it may be recycled. The sprayers 26 may be located above or below the beds 20, preferably those above being directed downwardly and those below directed upwardly. Removal of solid wastes from bed 20 is by means of pots 30. The scrubbed flue gases are drawn out of 18 by a pump 32 and passed to the atmosphere via stack 14. The reactant slurry is prepared from a solid reactant 36 in a bunker 38, the reactant being pulverized in a gas swept bowl mill 42. The pulverized reactant is entrained by warm waste gas from furnace 10 via lines 42 and 45. The temperature of the entraining gas is controlled by mixing gas direct from the furnace with a bled-off stream from the heater 16. The pulverized reactant is dried by the warm gas and passed into an enclosed slurry tank 62, where the entrained particles are washed out of the gas by water from nozzles 64. The gas, now freed from solid particles is passed via line 82 to the scrubber 18, and the slurry 68 is pumped from tank 62 to the scrubber 18 where it scrubs sulphur oxides from the waste gas.
