Title: Treatment of metallic ores
IPC: C22B5/00
Filed: 1956-11-05
Abstract: Compositions containing two or more metallic oxides or oxidic metallic components are contacted with a fused alkali-metal hydroxide at such a temperature that a liquid phase and a solid phase are formed, the liquid alkali metal hydroxide being enriched with respect to one of the metal values, and the solid phase being enriched with respect to another.  The two phases are then separated, for example by filtering, or decanting.  The separated liquid phase may then be cooled and leached with a solvent for the alkali-metal hydroxide, such as water, leaving the metallic oxide constituent as a solid. The leach solution, consisting of the alkali metal hydroxide, after settling of trace impurities, may be evaporated and recycled to the fusion step.  Sodium, potassium, lithium and cesium hydroxides are referred to.  Preferably the metallic oxide composition constitutes 1%-50% by weight of the mixture with the alkali-metal hydroxide.  In examples, iron oxide-titanium oxide ores such as ilmenite are treated with fused caustic soda, the titanium entering the liquid phase and the iron remaining as the solid.  Sodium chloride depresses the solubility of the titanium oxide and must therefore be avoided. However, the titanium dioxide may be recovered from the liquid phase after separation by adding sodium chloride to precipitate the titanium dioxide.  The lower the temperature worked at, the greater is the titanium-iron ratio in the liquid phase.  Any iron oxide suspended in the liquid phase may be removed by filtering through a sintered stainless steel filter with a pore size of about 5 microns. The liquid phase may be cooled to obtain crystals containing most of the titanium, either as titanium dioxide or a titanate, which are removed from the melt.  Other ores which may be treated by the process of the invention include tungsten-iron ores, in which the tungsten enters the liquid phase, chromite-iron ores with the chromium oxidised to the hexavalent state, in which the chromium enters the liquid phase, and vanadium-uranium ores such as carnotite, in which the vanadium enters the liquid phase.

Title: Improvements in or relating to slot aerials
Inventor: CHARMAN FREDERICK JOHN HENRY
IPC: H01Q13/10
Filed: 1953-12-09
Abstract: 756,381. Aerials. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 29, 1954 [Dec. 9, 1953], No. 34220/53. Class 40 (7). In order to increase the directivity and gain of a resonant slot aerial a plurality of effective shunt inductive elements are disposed at discrete intervals along the length of the slot so as to increase the phase velocity in the aerial beyond the free space velocity of propagation. This arrangement enables the physical length of the slot to be considerably increased. The inductive elements may be disposed at 30 degree intervals or less along the length of the aerial. They may consist of actual inductance units as shown in Fig. 1, or stub inductive units. It is stated that where n is the ratio in which the length of the slot is to be increased the inductive reactance X required for the inductive loading is given by where and 2L is the length of the slot, W is the width of the slot, and # is the free space angular spacing of the shunt elements along the slot. Inductive reactance may be introduced by other means as by short circuiting the slot and providing additional slot elements (2b, Fig. 3) adjacent to the short circuits to make them appear inductive. A similar effect can be achieved by embodying shorter transverse slots on either side of each short circuit of the main slot (Fig. 4, not shown), or by utilizing short circuits between sections of slot, each increased in width outwardly from the centre of the section (Fig. 5, not shown). The loading introduced need not necessarily be a simple inductance but may be compounded with capacity for use over more than one frequency range. The invention may be applied to an open ended quarter-wavelength " half slot (Fig. 6, not shown).
