Title: A process for the manufacture of basic zirconium sulphate
IPC: C01G25/06
Filed: 1946-01-11
Abstract: In the manufacture of basic zirconium sulphate, an aqueous liquid containing zirconium in sulphate solution and not containing any acid other than sulphuric acid and without the addition of any reagent containing a cation other than zirconium, is evaporated until the zirconium concentration reaches at least 24 per cent ZrO2, the SO3/ZrO2 ratio being between 0.8 and 3.0, preferably 1.0-1.6 at the beginning of the concentration, and the precipitated basic sulphate is separated. Crystallization may be brought about by agitation whilst the liquors are hot, and be speeded by seeding.  Insoluble impurities may be removed at an intermediate stage in the evaporation, e.g. when the ZrO2 content is 15 per cent, silica separating wholly or partly when concentration is effected above 75 DEG  C.  The basic zirconium sulphate yields the oxide on calcination.  The starting solution may be obtained by heating zircon sand &c., or used refractory bricks with calcium oxide and/or hydroxide, and if desired, a small quantity of calcium chloride, at, say, 1100-1250 DEG  C., washing the clinker, if desired, with dilute hydrochloric acid and water, and extracting with strong sulphuric acid up to 220 DEG  C.  The paste is heated to dryness, and then mixed with water to form a slurry which is treated according to the process of Specification 610,548 Specification 559,118 also is referred to.

Title: Improvements in or relating to Carbon Filament Electric Glow Lamps.
Inventor: BASTIAN CHARLES ORME
IPC: H01J5/30
Filed: 1916-01-26
Abstract: 105,929. Bastian, C. O. Jan. 26, 1916. Filaments; attaching; bulbs; residual gases; leading-in wires.-A carbon filament in the form of a close helix of small diameter is enclosed in a sealed bull containing inert as such as nitrogen or argon, or a mixture; a small quantity of mercury also may be included. In making the filament, a cellulose thread is wound on a mandrel, which may be of small diameter, say less than twice, and in no case more than four times, that of the thread, and may consist of a cellulose thread or wire. During winding, the mandrel, the filament, thread, or each, is moistened, either with or without heating; the application of warm distilled water is advantageous. Uniform spacing of the filament turns is secured by winding the thread in a continuous layer, with convolutions in contact, and binding the ends of the helix on to the mandrel. End portions for subsequent attachment to leading-in wires may be left unwound, and may be bent or twisted to provide an extended surface of contact with the paste The filament may be dried and set by heating to, say, 150‹ C., or by cooling, or drying may be effected otherwise than by heat and the filament caused to set by the application or paraffin wax or the like, or otherwise. The helix may be removed mechanically from the mandrel, which may be tapered for this purpose; or the mandrel may be dissolved by acid or electrolytically or destroyed by heat. Before carbonization, it is expedient to mount the helix on a smaller mandrel, to which the end portions may be secured, for instance by binding with cellulose thread. This mandrel and binding are removed before the filament is flashed and mounted. Joints with the leading-in wires are arranged as far as possible out of the heat zone. Water vapour, oxygen, and other harmful gases may be removed as described in Specifications 11,332/15 and 106,036. The filaments may be run at high temperatures with comparatively low current densities. Between the leading-in wires the glass or silica of the envelope may be cooled, for instance by mercury, oil, or air, to prevent electrolytic conduction. The ste mshown has separate hollow branches C, D for the leading-in wires. Mercury or tin amalgam is retained within the bulbs by capillarity or by packing such as asbestos or slag wool. Cooling is effected by distillation of the mercury. Pinch seals at the ends of the branches need only be mercury-tight. The outer parts A, B of the leading-in wires may be of copper and the inner parts A<2>, B<2> of tungsten alternatively, an ordinary platinum seal may be used. Specifications 2136/82, 6193/82, 13133/84, 29616/06, and 9250/10 also are referred to.

Abstract: 1372962 Axial-flow fans WOODS OF COLCHESTER Ltd 12 Jan 1973 [12 Jan 1972] 1552/72 Heading F1C In a variable-pitch axial-flow fan impeller each blade has, within the impeller hub, a laterally extending arm carrying a projection engaging a peripheral channel in an axially movable adjusting member coaxially surrounding and rotatable with the driving shaft, and the arm is detachably securable to the blade in at least two different positions. Each blade root 5 is secured to a carrier member 8 supported by a thrust bearing 10. An actuating arm 13 carries a roller 14 engaging a peripheral channel in an adjusting member 16 which is axially slidable on a cylindrical strip 17, the axial movement being effected against the action of a spring 24 by pneumatic pressure applied via a tube 31 to the space between a plate 32 and a diaphragm 46. Inward movement of the plate 32 and tube 31 under the action of the spring 24 is limited by a nut 42 which is adjustably screwed on to the threaded end of the tube 31, while outward movement is limited by adjustment screws 39 which form stops for sliding pins 35. A detachable cover 38 affords access to the mechanism. The blades 3 are available with either left-hand or right-hand pitch. In addition, each blade root 5 can be attached, as by screws 7, to its carrier member 8 in two different positions differing by 180 degrees, and the arm 13 can be attached, by a screw (26) and a pin (27), to the carrier member in two different positions. Eight different assemblies are therefore available according to the direction of flow through the impeller, the direction of impeller rotation and whether the blades are to be in the maximum or the minimum pitch angle position on failure of the pneumatic control. Inherent centrifugal turning movements acting on each blade assembly are opposed by counterweights 20 integral with the carrier member 8 and an auxiliary counterweight 25 attachable by a screw 28 to the carrier member in two different positions.
