Title: Preparation of microspheres
IPC: C01B31/30
Filed: 1965-04-02
Abstract: Dense spherical particles of a mixture which can be dispersed as a sol and which consists of carbon and at least one actinide metal oxide (At. No. 90-96) and optionally at least one rare earth metal oxide and/or zirconia, and/or hafnia, are made by forming a dispersion of a sol of the mixture in a non-boiling liquid medium in which the liquid of the sol has low solubility. "Low solubility" is defined in the Specification.  The sol may be an aquasol.  The rare earth metals are defined as those having atomic numbers 58 to 71 and yttrium.  The weight ratio of total metal oxide to carbon in the spherical droplets may be from 0.12 to 0.22.  The density of the liquid medium can be less than 1.0 g./cc.  The liquid medium may be a solution of water in a solvent in which its solubility is from 3 to 30% by weight, e.g. the liquid medium may be water and an alcohol having 4 to 10 carbon atoms, such as ethyl hexanol, hexanol or butanol.  The liquid medium can be at a temp. between 0 DEG  C. and 50 DEG  C. below its boiling point.  The liquid solvent may be recirculated and the water content controlled, e.g. to 6-7% by weight. The particle sizes of the solids in the sol are 20 to 20 mm diameter.  The dispersed droplets of the sol can be of a size such that spherical particles 5 to 500m  in diameter are produced. The spheres may be sintered under an inert atmosphere, e.g. argon at a temp. of 1585-1635 DEG  C. for 2 1/2 hrs., to produce the metal carbides. The spheres may be washed with pentane and dried before sintering.  The spheres can be used as a nuclear fuel.  In the examples a urania sol was prepared by autoclaving aq. uranous chloride at 100 DEG  C. and a zirconia sol by autoclaving aq. zirconyl chloride at 120 DEG  C.; the urania/carbon and zirconia/carbon sols were mixed using an ultrasonic probe.  The oxide sol may have a solids content of 1 to 40% by weight. The components are mixed in the presence of a dispersing agent, e.g. polyoxyethylene sorbitan laurates, oleates and stearates and an anti-foaming agent.

Abstract: 1,246,548. Transistor switching circuits; frequency shift systems. AVIMO Ltd. 10 March, 1970 [18 March, 1969], No. 14189/69. Headings H3T and H4P. An electronic relay comprises an oscillator 107 including a transistor and a transformer T1 having input, feedback and control windings, the control winding being connectable to a low resistance by control switching means, thereby inhibiting the oscillator. The oscillator effectively connects an output terminal 111 to a D.C. supply when it is oscillating and interrupts this circuit when it is not. It may be used at the interface of low and high voltage telegraph systems, the oscillator being in the high voltage system and being keyed by the low voltage system. As shown, there are two oscillators 107, 108 and their control windings 113, 114 are connected to a latching switching system whereby only one oscillator can oscillate at a time. By the use of leads to interconnect terminals 134 . . . 137 and 144, 145 various combinations of single or double current input and output can be arranged. Input and output have filters 120, 123. The control switching means comprise transistors VT1 ... VT4 connected to the D.C. terminals of diode bridges, whose A.C. terminals are across the control windings. The oscillators operate in a bi-stable manner, so that with no input signal one will be oscillating, e.g. 107; the voltage induced in its control winding is rectified by the associated diode bridge and a positive potential is applied to one of the transistors in the opposite switching circuit, e.g. VT3, which conducts to short-circuit the control winding of the other oscillator and inhibits it. A control signal applied to input terminals 117, 118 will switch on either VT1 or VT4 according to its polarity, thus stopping the associated oscillator and allowing the other to start. RC circuits R3, C1 and R6, C2 cause a delay in the starting of their oscillators. In the output side, the terminal 111 is connected either to positive potential terminal 109 or negative one 110. Diodes are used to protect the circuits against transients and reverse polarity.
