Title: Metal oxides
IPC: C01G43/025
Filed: 1965-06-11
Abstract: Dense particles of oxides of the actinide metals are prepared by forming a colloidal solution of the oxides of the metals, predominately in the tetravalent state, from an acid deficient solution (as defined below) of the nitrates of the actinide metals containing above 2 moles/l. of the metals and a molar ratio of nitrate: metals of 0.5-1.8: 1, subdividing the colloidal soln. into drops and gelling the drops by extraction of HNO3 therein by a liquid anionic exchanger (as defined below) contained in a water-immiscible solvent, and drying and calcining the gelled particles.  Specified particles are of UO2, UO2/ThO2, UO2/PuO2 and ThO2/ PuO2.  A liquid anionic exchanger is defined as a liquid capable of complexing with nitrate ions through a liquid/solid or a liquid/liquid interface, and exemplified exchangers are aliphatic primary amines and mixtures thereof. An acid deficient solution of the nitrate is a hydrolysed solution of the nitrate in which the equivalent nitrate concentration is less than the equivalent cation concentration, and may be formed from a solution of the nitrates by adding UO3 thereto, or by extraction of HNO3 therefrom by an anion exchanger.  The colloidal solution may be formed by catalytic reduction of the solution of a nitrate of a hexavalent actinide in an autoclave with H2, in the presence of Al2O3 carrying one of the elements Pt, Pd, Os, Ru or Rh. The colloidal solution may be divided by spraying into the anionic exchanger or by emulsifying the solution in the exchanger by stirring.

Abstract: 1304573 Signalling varifitions in frequency GENERAL ELECTRIC CO 26 May 1970 [29 May 1969] 25167/70 Heading G4H [Also in Division H2] A circuit for monitoring the frequency of, for example A.C. mains supply comprises a frequency responsive circuit adapted to produce a control pulse for each cycle of the supply whenever the frequency is below a preset range, a time delay circuit 70 adapted to provide an output signal a predetermined time after actuation of the time delay circuit by a control pulse and a timer 80 for disabling the circuit 70. The signal, the frequency of which is to be monitored, is fed to an harmonic eliminating circuit 16 and an undervoltage detector 20. A zero crossing detector 24 provides a series of reset pulses, one for each cycle, which are fed to a counter 40. A high frequency crystal controlled oscillator 30 enables the frequency of the supply to be measured and the detector 20 provides a blocking signal if the amplitude of the supply voltage falls below a preset level. Devices 48, 49, which are preset to frequencies F 1 , F 2  respectively where F 2  is lower than the normal supply frequency but higher than F 1 , are connected to logic circuits 46, 47 the outputs of which are fed to a control circuit 60 shown in Fig. 2. In the event of the supply frequency falling below F 1  the timing circuit 70 is started by a control pulse from the circuit 46 and after a delay provides a set pulse to a flip-flop 63 which generates a control signal for a circuit breaker in a power system, an alarm &c. If the frequency momentarily returns to a value above F 1  the timer 80 generates a pulse to discharge a condenser of the delay device in the circuit 70, the circuit 70 restarting its timing interval when the next control pulse, indicating that the frequency is below F 1 , is received. When the frequency rises above the value F 2 , the circuit 47 stops supplying control pulses to a timer 90, which after a delay following the receipt of the last control pulse provides a reset pulse to the flip-flop, thereby terminating the control signal to the circuit breaker. The circuit may be arranged to respond to over-frequency conditions.
