Title: Removal of chlorides from aqueous nitrate solutions resulting from processing of spent nuclear fuels
IPC: G21C19/46
Filed: 1961-06-29
Abstract: Uranium is recovered as uranyl nitrate solution from neutron-irradiated fuel elements in which the uranium is associated with a nitric acid-resistant metal by dissolving in a chloride-containing nitric acid, adjusting the nitric acid concentration to 5-10M, and countercurrently contacting the solution with NO, NO2 N2O3 or N2O4 at a temperature, usually 20 DEG  to 30 DEG C., such as to evolve a chloride-containing vapour consisting essentially of NOCl.  The fuel element may comprise a core of uranium or a mixture or alloy thereof with molybdenum or silicon or a cermet of uranium oxide and stainless steel, the core being clad and/or bonded to stainless steel.  Fig. 3 illustrates a cyclic process involving recycling of HCl and HNO3 which includes an additional step 18 of contacting the chloride-reduced solution with NO formed by hydrolysis of nitrosyl chloride in hydrogen chloride recovery column 14 plus make-up NO.  In column 14 the countercurrent contact of nitrosyl chloride with water results in the formation of an upper zone from which NO may be withdrawn, an intermediate zone from which HCl is returned to storage tank 16 and a lower zone from which HNO3 is returned to the chloride-reduction column 12.  The product leaving step 18 may be used directly for liquid-liquid extraction of uranium, e.g. with ethyl ether, methyl isobutyl ketone, or tributyl phosphate in a kerosene solvent.

Abstract: 501,594. Lubricating ; bearings. KIPOUROPOULOS, N. Aug. 28, 1937, No. 23600. Convention date, Aug. 28, 1936. [Classes 12 (i) and 12 (iii)] The bearings 13, 13<1>, for an electric trainway trolley-arm roller 3, are lubricated when running, by oil which is collected from a reservoir 4 by an upstanding flexible conduit 6. The oil passes through a horizontal groove 5 in the fixed axle 2 to the bearings, and excess is returned through holes O, O<1>, to the reservoir 4. Oil leakage is prevented by helical channels 7, 71 in the axle 2, and by spring pressed packings 8. When the roller 3 is stopped oil runs down outwardly flared channels 9 in the sides of the reservoir 4 and into the bearings through holes 15. When the roller is assembled the flexible conduit 6 lies within the groove 5. The number of couduits 6 and channels 9 may be increased. The interior of the roller may have conical recesses 16 so that when the groove 20 on the roller has worn excessively oil escapes on to the overhead line and its presence indicates that the roller requires renewing.

Filed: 1936-08-31
Abstract: 482,867. Mercury switches ; electromagnetic and magnetic switches. CIANCHI, A. Aug. 31, 1936, No. 23734/37. Divided out of 481,289. [Class 38 (v)] In a magnetically or electromagnetically - operated switch such as a mercury switch having a glass or like vessel through which a conductor passes to convey current within the vessel, the conductor is made of magnetic material, is sealed to the vessel wall by fusion, and serves to bring a magnetic field to a point inside the vessel. As shown in the Figure, a magnetic member 2 is fused into the top of a sealed casing 1 the reduced lower end of the member 2 normally dipping into mercury trapped in a float 4 carrying in its upper portion a cylindrical magnetic armature 8. An electromagnet 9 surrounds the vessel 1 and on energization draws down the armature and float so that mercury from the main body 5 enters the float by a side passage 7 and unites with the mercury trapped therein so completing the circuit between the contact 2 and a lower contact 3. A pair of magnetic spring arms 10 are secured to opposite sides of the member 2 and as the armature moves down the ends of the springs, which bear normally on the inside surface of the cylindrical armature 8, snap over the upper end of the armature so that even if the electromagnet 9 is de-energized the armature remains in its lower position. The armature is released by energization of a second electromagnet 14 surrounding the member 2 outside the vessel and causing it to attract the two springs 10 which are provided with enlargements 11 opposite enlargements 12 on the member 2 for this purpose. In a modified arrangement, Fig. 2 (not shown), a single operating solenoid is mounted within the sealed casing, through the top of which projects a magnetic conductor 2 in a manner similar to that previously described.

Title: Improvements in electric transformers
IPC: H01F29/12
Filed: 1926-09-27
Abstract: 279,993. Heyes & Co., Ltd., and Jones, B. E. Sept. 27, 1926. Sparking, preventing.- A transformer is provided with a secondary winding in the form of a detachable plug element connected by flexible leads to the load such as a lamp or motor to be supplied, and a switch adapted to be operated by insertion of the plug is provided in the primary circuit. The primary coils 3, 4 are arranged on a laminated core 5, the magnetic circuit of which is completed when the transformer is in operation by a laminated member 10 carrying the secondary winding, and forming part of a removable plug element 7. In the lower part of the casing 1 there is provided a double pole switch 20 controlling the primary circuit, and the operating member 19 of the switch is arranged to project into a slot 18 in a plunger rod 16 which is urged upwardly to maintain the switch in an open position by a spring 21. Insertion of the plug element displaces the rod 16, as shown, to close the switch. The plug 7 is retained in position by a pin and slot connection with the casing which necessitates turning the plug before disconnection, thereby reducing the load current before the switch opens. A hinged inspection door 25 is interlocked with the switch mechanism by means of a forked bracket 26 which embraces the rod 16 and is slotted to permit the passage of pins 28. These pins serve to prevent opening of the cover when the switch is closed by engaging the bent ovtr ends 27 of the bracket 26. When the switch is in the open position and the cover is opened, closing of the switch is prevented, until the cover is closed, by a forked member 29 which moves forward under the influence of a spring 30 when the bracket 26 is withdrawn and engages under the pins 28, the rod 16 then being in the raised position.
