[Class 49.] Food enclosed in aluminium &c. cans, or glass, earthenware, or other containers is sterilized and subsequently cooled in a retort 1 which is kept completely filled with water under pressure during the sterilizing and the cooling first under a supply of steam at a pressure higher than the working pressure and then by a supply of cooling water at a pressure equal to or higher than the working pressure, the excess water in the retort resulting from the condensation of the steam introduced for heating, and also upon completion of the process the hot sterilizing water, being forced out through a relief valve 4 located in the upper part of the retort 1, the load on this valve determining the pressure of the water in the retort. As shown, steam for heating is supplied to the retort 1 through a pipe 6 and valve 7 controlled by a temperature regulator 8 and having a byepass with valves 10, a stop valve 11 being also included. The pressure-relief valve 4 which may be weight or spring-loaded is connected through a pipe 14 and non-return valve 17 to a hot water holder 16, and also through a pipe 18 and a valve 19 to the drain pipe 20. When sterilization has been completed, cooling water under pressure is supplied to the retort 1 through a pipe 12 and, valve 19 being closed, displaces the hot water into the holder 16 in which it is retained until required for subsequent sterilization operations, on which it is returned to the retort through a valve 24 and a pipe 25. The holder 16 has a safety valve 21 connected by a pipe 22 with the discharge pipe 20. When the hot water has been removed from the retort, the valve 19 may be opened to allow further cooling water to be sent through the retort. Before removing the containers, the cooling water is drained off through a valve 23 and pipe 20. The liquid in the retort 1 traps and compresses a body of air in a container 2, closed at the top and communicating through a water seal 3 with the retort, into which part of the liquid from the retort flows when the retort is placed under pressure and from which on fall of pressure liquid will be forced back into the retort to counteract the fall. Oil and fat carried into the retort 1 by the cans &c. floats to the top of holder 16 which may be provided with means for skimming it off.

Title: An improved method of recovering uranium from solution
IPC: C22B60/02
Filed: 1957-11-27
Abstract: <PICT:0822431/III/1> A solution of a uranyl salt is mixed with an alkali metal or ammonium fluoride and formic acid, and heated to 90 DEG  C.; sulphur dioxide is passed in to precipitate a double fluoride of the alkali metal or ammonium and uranium which is then separated, mixed with calcium and magnesium and heated to obtain metallic uranium.  Alternatively, where ammonium uranium fluoride is obtained, this may be separated, washed, dried and heated to 250 DEG C. in a dry inert atmosphere to form uranium fluoride and ammonium fluoride (which volatilizes) and the uranium fluoride mixed with calcium or magnesium chips and heated to obtain metallic uranium.  In one embodiment, an ore such as pitchblende or autunite which is poor in uranium is attacked with nitric acid to form uranyl nitrate in solution, the solids are separated and the solution extracted with a solvent for the uranium such as tributyl phosphate; the extract is re-extracted with water and the organic phase reused in the first extraction.  Ammonium fluoride and formic acid are added and sulphur dioxide bubbled in whereby dense green UF4.NH4F is formed.  This reaction may be performed in the apparatus shown in Fig. 2, the solution entering a steamjacketed reactor 11 through line 16 and leaving through line 17, sulphur dioxide being passed in through perforated ring conduit 15 whilst gases (CO2) arising in the reaction are vented at 18 and the precipitate being withdrawn through tube 10. Radial bars 14 are connected to shaft 13 which agitates the mixture by continuous rotation.  The precipitate is washed, dried and heated to 250 DEG  C., e.g. in a current of nitrogen, and then reduced to metal by reaction with calcium or magnesium chips. Uranyl sulphate may also be used as the starting material.  In a statement of prior art for the recovery of uranium from ores, the following steps are referred to: attacking the ore with mineral acid and separating the residues; precipitating some metallic hydroxides with sodium carbonate; breaking-up the uranyl-carbonate complex with nitric or sulphuric acid; precipitating sodium uranate with caustic soda and dissolving the precipitate in nitric acid; extracting with an organic solvent; treating with hydrogen peroxide to precipitate UO4, which is then calcined to UO3; reducing the latter to WO2 with hydrogen or ammonia; converting to UF4 with gaseous hydrofluoric acid and finally reacting the fluoride with calcium or magnesium to give metallic uranium.
