Title: Uranium recovery from ore concentrates
IPC: C22B60/02
Filed: 1964-01-15
Abstract: Prior to treatment for obtaining uranium, oxidic ore concentrates are treated with ammonium bifluoride to remove silicon as SiF4 and/or other volatile silicon fluorides.  At least 0.15 parts by weight of the bifluoride should be used per part of concentrate and the heating temperature is preferably 125-150 DEG  C.ALSO:Oxidic ore concentrates containing uranium and contaminants are treated with a magnesium chloride containing flux at a temperature of 600-900 DEG  C. while agitating the mixture in contact with air, an excess of a magnesium-zinc alloy is then added to reduce the uranium compounds present, the excess combining with the uranium to form a U-Mg-Zn alloy from which the contaminant containing flux is then removed. The alloy may then be heated at about 900 DEG  C. in an inert gas or vacuum to volatilize off the magnesium and zinc, the uranium being remelted to obtain a solid, sound ingot.  The alloy may be arc-melted but is preferably heated by induction or resistance heating.  MgCl2 is an essential ingredient of the flux but one or more of CaCl2, KCl and NaCl may be used as diluents, there being however at least 10 atom per cent of the Mg++ cation therein (preferably 15-60 atom per cent).  From 2-20 mole per cent of MgF2 or CaF2 may preferably be added to the flux.  A pretreatment step for removing Si by treatment with NH4HF2 is also described (see Division C1).

Abstract: 581,926. Reproducing photographic records using polarized light. KODAK, Ltd. (Eastman Kodak Co., Hanson, W. T., and Evans, R. M.). Feb. 3, 1943, No. 1786. Drawings to Specification. [Classes 97 (i) and 98 (ii)] A method of photographic reproduction comprises masking a photographic record with a vectograph image corresponding thereto and making the reproduction from the original, so masked, with polarized light. The masks may be used for colour, tone, or contrast correction. By adjusting the plane of polarization of the polarized light relative to the vectograph the effective contrast of the mask can be modified at will. The light may pass through a polarizer anywhere between the light source and the light sensitive surface. Various types of vectograph are referred to. A black-andwhite, coloured, or multi-coloured vectograph may be used. The original may be black-andwhite or coloured, and the mask may be printed therefrom by contact or projection printing. The printing may be arranged to give a diffused mask as described in Specification 579,239. In the production of the vectograph, an intermediate wash-out relief image may be made from which vectograph ink is .imbibed by a vectosensitive layer. The production of an intermediate negative may be necessary. The reproduction may be made on to colour component negatives successively or on to multilayer or other differentially sensitized material image contained by the vectograph should be printed from the transparency by light of the proper colour to give the colour correction desired in the reproduction. In the reproduction the mask is preferably in contact or substantially in contact with the original, but may be in register with a projected image thereof. The mask may be used successively to correct different colour component images, the contrast being altered by rotation of the polarizing filter. The existence of a constant density image in the vectograph is not detrimental. Specifications 512,608, 528,796, 547,554, 551,614, 553,196, 553,229, 553,230, 556,578 and 581,937 also are referred to.

[Class 37] A wavemeter for ultra-short-wave radio comprises a section of concentric transmission line, the inner and outer conductors being conductively connected at one end, means including a disc for varying the tuning, and 'means for indicating the effective electrical length at resonance points. The resonance indicator can be a thermo-couple and millivoltmeter ; or a diode detector, crystal rectifier and current responsive instrument. The wavelength indicator is a section of a meter stick. Concentric line elements 1, 2 open at the end on support 9 are connected by a metal member (i through which slides a meter stick 7 secured to a metal piston disc 3 in contact with the line parts 1, 2, a mica spacing washer 11 being provided. A thermo-electric indicator 12 ... 14 is shown. With the line parts completely open-ended, the stick 7 at resonance conditions will measure quarter-wavelengths, but if a short-circuiting coupling strap 15 is employed, the stick will measure half-wavelengths. Capacitance coupling can be effected by plates 16, 17, Fig. 2, the line part 1 being provided with an exploring electrode 18. The piston disc 13 may be made of phosphor bronze. A modified construction comprises a calibrated resonance meter, the inner part 1 with exploring electrode being adjusted by a screw-threaded shaft carrying a graduated scale dial, and the piston disc and meter stick being dispensed with. In this construction, the inner and outer line sections are rigidly connected together at the adjustment end. Vernier scale adjustments can be employed. Instead of the internal detector, measurements can be effected externally by employing the energy absorption at resonance to react on the high-frequency source. Such reaction can be made to effect a sudden change in current in one or other of the electrode circuits of an oscillator valve, or a slight frequency change which can be detected by a beat method.
