Title: Process of recovering valuable components from red mud
IPC: C01F7/30
Filed: 1963-02-12
Abstract: <PICT:1014072/C1/1> Red mud, obtained by alkali treatment of bauxite, is treated to recover its constituents in a process which comprises slurrying the mud in water, passing in sulphur dioxide until the pH of the slurry is 3.5-6, separating the insoluble residue from the liquid, which contains the sodium values in the form of the bisulphite with possibly a little sulphite, suspending the residue in water and passing in sulphur dioxide until the pH is 1.5-2.3, separating the liquid from the insoluble residue, which is rich in iron and titanium oxides, heating the solution to drive off some of the sulphur dioxide until the pH is 2.5-3.0, thereby precipitating silica which is separated and recovered, and further heating the remaining solution to drive off more sulphur dioxide until the pH is above 3.5, to precipitate basic aluminium bisulphite, which is separated, dried, and calcined at 500-700 DEG  C. to give alumina. The remaining solution may be added to a further portion of the initial red mud slurry. The evolved sulphur dioxide may be similarly recycled.
Patent GB-435450-A (GB)
Title: Improvements relating to the electrolysis of water
IPC: C01B5/02
Filed: 1934-02-21
Abstract: In the electrolysis of water for the concentration of "heavy" water, the water vapour carried off by the gases is condensed before washing of the gases and is employed as feed to an electrolytic cell in the next stage of concentration.  The feed water may serve for washing. The washed hydrogen may be brought into intimate contact with the feed-water in a coke tower, the "heavy" hydrogen interacting with the water to form a certain amount of "heavy" water.  The hydrogen from the later stages of concentration is liquefied and the "heavy" and "light" gases are separated by fractional distillation.  The "heavy" hydrogen so obtained is burnt in air, yielding almost pure "heavy" water. Specifications 219,381, 261,164, 320,388, and 335,987, [all in Class 41], are referred to.

Title: Dynamoelectric machines
IPC: H02K9/19
Filed: 1975-02-11
Abstract: 1496014 Cooling dynamo-electric machine rotor windings; electric connectors WESTING- HOUSE ELECTRIC CORP 11 Feb 1975 [21 Feb 1974] 5723/75 Headings H2A and H2E [Also in Division F2] A dynamo-electric machine rotor has a central bore containing two concentric tubes forming inner and annular shaft passages for coolant liquid; means for connecting these passages to passages in the windings said means comprising a member disposed in the bore containing two separate flow chambers connected to one each of the shaft passages and to radial passages through the shaft connecting to the winding passages; and two insulated conductors disposed in the shaft bore and enclosing the concentric tubes. A turbogenerator rotor 18 (Fig. 4) coupled to an exciter set rotor shaft is cooled by water flowing through the hollow winding conductors 28, 26 the water being passed from the outside through central bores in the exciter and generator rotors. The generator shaft 23 carries two concentric steel tubes 42, 44 forming an inner passage for the inflow of cooling water and an annular passage for outflow. A member 75 is shrunk-fitted into the bore and comprises (Fig. 6) a central tube 78 joined to the tube 42 by a snug fitting ring 81. This tube 78 has radial passages 80 communicating with radial tubes 64 in the rotor, the join being welded for fluid tightness. The tubes 64 communicate with two chambers formed in an annular space 66 in the rotor periphery (Fig. 4), there being four channels in all, of 90 degrees each (Fig. 5, not shown). These chambers communicate via hydraulic lines 68 including insulating connectors 67 to the hollow conductors. The return lines communicate with the other two part annular chambers which connect via further radial passages 64 to an annular passage 77 in the transition member 75 (Fig. 6). The member 75 is connected to the tube 44 in the rotor by a fluid tight weld. In the central bore of the rotor are positioned two semi-cylindrical insulated conductors (50, 51, Fig. 2, not shown) surrounding the outer tube 44. Connection to the rotor wingings therefrom is made by radial copper pins 62 threaded into the semicylindrical conductors and connected to leads 63 passing to the windings. At the junction between the exciter shaft and the generator shaft (Fig. 3, not shown) the inner tubes (37, 47) are joined by an inner snug fitting sleeve, the outer tubes (38, 44) carry flanges, one being screwed on, and these are bolted together, an 0-ring completing the fluid seal. The conductors are partially cut away and have flexible leads bolted thereto, these passing outside the flanges and are brazed to contact blocks which are themselves brazed together. Mechanical coupling of the shafts is achieved by bolting a splined or keyed sleeve on the exciter shaft to a flange on the generator shaft. The sleeve can thus be unbolted and slid back to provide access to the conductors and/or coolant tube couplings.
