Patent GB-862613-A (GB)
Title: A process for separating cerium from other rare earths
IPC: C01F17/271
Filed: 1958-08-25
Abstract: Cerium, and thorium if present, are separated from other rare earth metals by contacting an aqueous suspension of hydroxides, carbonates or basic salts of said metals with a quantity of chlorine 10-30% in excess of that theoretically necessary to oxidise the cerium to the quadrivalent state whereby a basic cerium chloride forms together with thorium oxide or basic chloride, and subsequently dissolving the trivalent rare earth metals as chlorides with hydrochloric acid.  The oxidation with chlorine is preferably performed at 40-50 DEG C. and the subsequent step at 60-80 DEG C. and to a final pH of 2.2-2.8.  It is also preferred to pass in chlorine gas during the subsequent step and to include in the hydrochloric acid 5-20% by weight of sulphuric acid, based on the weight of cerium oxide present in order to improve the degree of separation and the filtrability of the precipitate.  By increasing the final pH to 3.5-4, e.g. with aqueous ammonia, any thorium solubilised with the trivalent rare earth metals may be precipitated.  The residue of cerium and thorium compounds may be separated e.g. by the process of Specification 855,481 rare earth metals in the solution may be recovered by precipitation with sodium carbonate.

Title: Electrical power transfer system
IPC: H03K17/72
Filed: 1965-06-22
Abstract: 1,108,964. Substituting electric power supplies. BOEING CO. 22 June, 1965 [26 June, 1964; 14 Sept., 1964], No. 27277/67. Divided out of 1,108,963. Heading H2H. A power supply system wherein a load is supplied from one or other of two alternating current power supplies comprises selective control means responsive to the phase relationship and output voltage level of the two supplies whereby to disconnect the load from one supply and connect it to the other supply when the two supply voltages are in phase and at zero voltage levels. In a system wherein a load 100 is the electrical devices of an aircraft, the load is normally supplied, whilst the aircraft is on the ground, from a ground power unit 101 by way of current control device 103 which comprises a pair of reversely connected thyristors, a control switch 110 being in the position 111 thus causing a zero power detector 122 to operate a control unit 130 to produce signals to render the thyristors in the control device 103 conductive. When it is desired to change the source supplying the load 100 from the ground power unit 101 to the air power unit 106 the control switch 110 is moved from position 111 to position 112, this movement however only preconditioning the switching on of the air power unit 106 and the switching off of the ground power unit 101. A unit 115 is provide to detect the phase coincidence of the supplies from units 101, 106 and is effective to cause a zero power detector 120 to produce a signa when there is phase coincidence between the two supplies and the voltage level of the unit 106 is zero. The signal from the detector 120 causes a control unit 125 to produce firing signals for the thyristors in the current control device 108 thereby connecting the air power unit 106 to the load 100 when the output voltage of the unit is zero. The control unit 125 also produces a signal 127 which disables the zero power detector 122 so that no firing signals for the thyristors in the current control device 103 are produced. Thus at a zero voltage level of the output of the ground power unit 101 the supply to the load from that unit will be switched off. Each of the units 115, 120, 122, 125, 130 comprise one or more thyristors.
