IPC: C01F15/00
Filed: 1960-12-07
Abstract: Hydrothermally stable sols. comprising homogeneous colloidal particles of ThO2 and UO2 dispersed in water and/or heavy water substantially free from electrolytes, are prepared by gradually removing by hydrolysis anions from an aqueous solution of thorium chloride and uranium tetrachloride until the solution is substantially free from electrolytes.  The anions may be removed by dialysis using an anion-permeable membrane or by passing the solution through a bed of anion-exchange resin in the hydroxide form.  The aqueous solution may be maintained at an elevated temperature, preferably 60 DEG  to 100 DEG C., in a reservoir and gradually fed first to the anion-removing station where the solution temperature is preferably 15 DEG  to 35 DEG C., and then back to the reservoir, the operation being continued until the solution is substantially free from electrolytes.  The sols. may be clad with silica to improve their hydrothermal stability, by adding a silica sol., e.g. containing 2% SiO2 to the thoria-urania sol. preferably followed by stabilization of the product by heating under non-evaporative conditions in the presence of a base, e.g. metal hydroxides, especially sodium hydroxide, which is stable under reaction conditions and which contains elements of low thermal neutron cross-section.  The sols. may be diluted by the addition of de-ionized water or water of low ionic content.

[Also in Division F1] A submersible vessel comprises at least one ballast chamber a, Fig. 1, (not shown), containing a gas d in pressure equilibrium with the external water f through orifices e which allow the external water to penetrate into the chamber to a level g, a reservoir i containing the gas d under reduced volume in the liquid state, a vaporizer I for drawing gas from the reservoir i increasing its volume and delivering it to the chamber a and a liquifier j to draw gas from the chamber a reduce its volume and return it to the reservoir i. The vaporizer l and liquifier j are controlled from the cabin c to maintain the level g and consequently the buoyancy at the desired height, if it is lowered to g 2  the vessel's buoyancy is positive and it rises, if it is raised to g 1  the buoyancy is negative and the vessel descends. The cabin C accommodates the crew and the walls are capable of withstanding the maximum external water pressure. The engine compartment b is maintained at the external water pressure through the aperture h and like the chamber a has non-pressure resisting thin walls. A vent k is provided from the reservoir i so that if the apparatus j and I cease to function the gas in the reservoir will gradually assume the temperature of the water f and expand to enter the chamber a. The reservoir i may contain the gas in solution with a liquid or merely compressed in which case the apparatus l would be an expansion valve and the apparatus j would be a compressor. The engine compart. ment b may have pressure resisting walls. The chamber a may be a flexible balloon. A further embodiment describes the ballasting arrangements incorporated into a vessel which can be used for lifting loads and samples from the bottom of the sea, in which two forward, two aft and two midships ballast chambers are used and which by variation of trim in association with a rudder and fins can assist or replace the motive equipment of the submarine. A further embodiment describes a submarine scooter in which compressed air is supplied to a propulsion engine through an expansion valve the exhaust gases of which are cooled and passed to a ballast chamber in which the water level is adjusted by a pivoted pipe whose outlet level can be varied.
