Title: Process for separating and purifying compounds of metals which form insoluble or difficultly soluble compounds
IPC: C01F17/00
Filed: 1957-04-26
Abstract: A process for the separation and purification of a water insoluble or difficultly soluble metal compound from a mixture of such metallic compounds comprises extracting said water insoluble or difficultly soluble metal compound with a metal salt solution which forms with said metal compound and is capable of forming with at least one other metal compound present, soluble complex compounds, the metal salts used for the extraction being salts of aluminium, boron, scandium, zirconium, vanadium, niobium, tantalum, antimony, chromium, molybdenum, tungsten, uranium or iron.  The extraction process may be repeated so as to successively separate the metal compounds forming the soluble complexes.  The extracting salts may be complex, e.g. complexes of chromium, molybdenum or tungsten with oxalic acid. Aluminium salts are preferred, e.g. potassium alum, ammonium alum, aluminium nitrate, aluminium citrate and aluminium-oxalic acid (see Specification 866,718).  The extraction may be performed in a column when the extracting solution may, if desired, flow in an upward direction, or in stages in a number of vessels.  The extraction may be performed in an aqueous medium or in an organic solvent such of methanol or ethanol or their mixtures with water. The insoluble complexes to be separated are preferably used in a highly active form, preferably freshly precipitated and in a highly dispersed form in a solvent medium.  Enforced convection, e.g. by stirring may be used.  The extraction may be effected in two stages, first with the metal salt solution and then with pure solvent.  The insoluble metallic compounds to be separated may be oxalates and the extraction solution may contain the preformed soluble oxalato complexes of several of the elements to be separated.  Examples describe (1) the successive extraction of soluble rare earth complexes by treating a mixture of rare earth oxalates with potassium alum, and (2) the extraction of a soluble nickel complex from mixed nickel/cobalt oxalates with ammonium alum.  Reference is also made to the separation of yttrium earths including scandium and yttrium by extraction of the oxalates with aluminium salts, e.g. aluminium nitrate or alum.

Title: Carrier wave receiving systems
IPC: H03G5/02
Filed: 1937-05-14
Abstract: 480,839. Wireless receiving-apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 14, 1937, No. 13697. Convention date, July 9, 1936. [Class 40 (v)] The selectivity and tone control elements of a radio receiver are mechanically or electrically interdependent. In Fig. 2, the tone control shaft 3, operating a variable resistance 2, carries a cam 4 which during part of its revolution depresses lever 6 thereby decreasing the selectivity by increasing the coupling between the inductances 8, 9 ; in the position of cam 4 shown, the high note amplification due to resistance 2 is a maximum while in the last 90‹ of rotation selectivity is being varied, and the tone control varies little if at all. Fig. 5 shows a further development in which control of selectivity through tone control shaft 2, cam 4, lever 6 and coils 8, 9 is prevented when the wave-range switch shaft 15 of the receiver is at a certain setting, when a cam 16 similar to cam 4 depresses the arm 6, thereby giving fixed maximum selectivity on any desired wave-range and removing control of selectivity from the tone control cam 4. Fig. 9 shows an electrical equivalent of the mechanical conjoint control system of Fig. 2. Selectivity is automatically controlled by means of rectified potentials across resistance 9 from rectifier 7, these potentials varying the impedance of valve 5 acting as a variable shunt to the common coupling resistance 14 of the filter 1, 2, 3, 4. Tone control is effected, also automatically in dependence on received strength, from resistance 13 and rectifier 11. The characteristic of the system is made similar to that obtained by the arrangement of Fig. 2 by arranging that a delay bias is applied to rectifier 7 equal to the voltage at point A corresponding to maximum tone colour or high-note amplification; the variation in selectivity thus occurs when the tone control remains approximately constant.
