Title: Improvements in or relating to the separation of cobalt and nickel
IPC: C01G51/04
Filed: 1956-04-19
Abstract: <PICT:0795410/III/1> Cobalt and nickel, present together in aqueous solution as salts, e.g. chlorides or sulphates, are separated by adjusting the pH of the solution to approximately 2 if necessary, treating said solution at room temperature with gaseous chlorine and one or more alkali and/or alkaline earth metal carbonates at a pH which rises to and is maintained at approximately 3 until substantially all the cobalt present has been precipitated as hydroxide, allowing the pH to rise to 4 to complete the precipitation, rapidly removing and immediately washing said hydroxide.  As illustrated in Fig. 2, sodium carbonate solution is supplied from vessel 1 and through spray distributers 7 and 8 to stirred reaction vessel 5 containing the cobalt and nickel solution, and chlorine is supplied from cylinder 2 through conduits 3 and 4 having porous diffusers.  The pH of the solution is measured by a chain of glass-calomel electrodes in a cell 11 to which the solution is continuously supplied.  In the example, a chloride solution is brought to a pH of 2 by passing in chlorine and the pH maintained thereafter, by means of the chlorine and sodium carbonate at 3. When the cobalt is substantially all precipitated the pH is allowed to rise to 4, and addition of chlorine and carbonate is then stopped, and the mixture filtered (device 14) and washed. The carbonate may in general be used in the form of a solid or as a solution or suspension, and it is preferred to use a carbonate the cation of which is not precipitated by the anions in solution.  Such oxides as CoO2 and Co3O4 may be formed, e.g. if the pH rises unduly.

Title: Improvements in or relating to mechanically operated time switches, particularly forswitching electric circuits in and out
IPC: G04F3/02
Filed: 1934-04-24
Abstract: 436,968. Time switches. KARLSSON, A. B., 82, Gitschinerstrasse, Berlin. April 24, 1934, No. 12359. [Class 38 (v)] In a short-time switch in which a knob 11 is rotated by hand through a predetermined number of revolutions or partial revolutions to wind up a spring 37 and then returns slowly under the action of the spring and the control of escapement mechanism 44 to cause, at the end of its return movement, the " on " or " off " movement of a switch which may also be independently operated by hand, the knob 11 is mounted on a spindle carrying a pin 33 which engages the teeth of a serrated disc 30 in the manner of a Geneva stop so as to cause the disc 30 to move on step by step while the knob 11 continuously rotates ; the disc 30 carries an indicating disc 36 marked in hours and the knob 11 is also provided with an indicating flange marked in minutes. The switch itself comprises a contact lever 27 and a hand lever 9, both pivoted at 25 and connected by a deadcentre spring 21. A projection 22 on the lever 27 is adapted in certain circumstances to engage the end of a spring-biassed lever 29 but normally the lever 29 is pressed into the position shown by a pin 31 on the disc 30. The switch may then be operated on and off by hand without interference. To use the device as a time switch, the knob 11 is rotated till the desired number of hours and minutes are indicated on the dials 36 and 10 and then released. The first movement withdraws the pin 31 from the lever 29. The hand lever 9 is then moved into its other position but the contact member 27 is held latched till at the end of the slow running-down movement the pin 31 re-engages the lever 29 and releases the member 27. The action is similar whether the switch is originally " off " or " on," but in one case the nose 22 is above and in the other case below the end 29<d> of the lever 29.

Filed: 1963-03-29
Abstract: 1,043,543. Processing spent nuclear fuel. MINNESOTA MINING & MANUFACTURING CO. March 29, 1963, No. 12589/63. Heading G6R. Radio-active and fissionable products are recovered from a mixture of these materials with carbon, e.g. a graphite clad spent nuclear fuel element, by a process in which the carbon is oxidized by heating the mixture in an atmosphere consisting of an inert gas and less than 7% by volume of oxygen. The nuclear fuel, e.g. uranium, remains behind, together with the non-volatile fission products, as the oxide and the volatile fission product oxides pass on together with CO2 and are trapped downstream of the furnace. The preferred atmosphere contains at least 3% by volume of oxygen at no more than 5% and the preferred heating temperature is 1550-1650‹ F. The inert portion of the atmosphere is preferably from Group O of the Periodic Table having an atomic weight of less than 200, e.g. He. The uranium is extracted from the residual oxide by the established nitric acid-T.B.P. process. The exhaust gases from the furnace contain CO2, some CO, inert gas, e.g. He, some oxygen and the volatile fission products. A nickel catalyst converts Co to Co2, a cold trap removes the most volatile fission products, pyrogallol removes oxygen, a hot copper coil removes iodine, tellurium and ruthenium, and purified lime water removes Co2. A further cold trap removes Xe and Kr, leaving He for possible re-use.
