Title: Improvements in or relating to the recovery of uranium
Inventor: SIMPSON ALEXANDER MILNE
IPC: C01G43/01
Filed: 1958-12-08
Abstract: Uranium is recovered as oxide from a uranium/molybdenum alloy by heating the alloy in an oxidising atmosphere to form and remove molybdenum trioxide leaving a residue of uranium oxide.  The oxidation is preferably effected in a current of oxygen at a pressure between 0.2 and 0.5 mm of mercury.  The alloy treated, for example containing 9% molybdenum, may have been irradiated in a nuclear reactor and contaminated with fission products.  Such an alloy may be heated in a tubular furnace to 1050 DEG C. in a flow of oxygen, whereupon a crystalline sublimate containing molybdenum trioxide forms on the cooler part of the furnace.  As shown in the Figures, the alloy is initially contained in a boat 7 in an electrically heated furnace provided with heating coils, 3a, 3b and 3c and with zeolitic molecular <PICT:0879580/III/1> sieves 4. The first two sets of the molecular sieves have a pore size of 13A DEG  and the remaining sieves have a pore size of 5A DEG .  In operation, the boat 7 is initially heated to 1050 DEG C. whilst oxygen is passed over and when sublimation is complete, the zone surrounded by coil 3a is cooled to 800 DEG C. whilst an inert carrier gas is passed through. The heating zone is then moved forward through coils 3a, 3b, and 3c until the sublimate is moved into the p  trap 4.  Molybdenum trioxide is retained in the heated part of the trap surrounded by coils 3c whilst fission product metal oxides and some iodine is deposited in the cool unheated portion of the sieve beyond the electric heating coils.

Title: Apparatus for continuous treatment of fibers with organic gaseous materials
IPC: F26B13/02
Filed: 1957-12-20
Abstract: Apparatus for the continuous treatment of fibres with organic gaseous material is characterized in that a gas seal forming device is provided respectively at a fibre inlet portion and an outlet portion, said device being arranged to prevent reaction gas escaping from a reaction zone by pressing an inert gas which does not participate in the reaction into the said device under pressure.  As shown in Fig. 1 endless conveyers 1 and 2 move around wheels 3, 4, 5, 6, 7, 8, 10, 9 and 91, 101, 11, 12 respectively.  Fibre inlet and outlet portions 17, 18 are located at the ends of charging and discharging portions 14, 16 themselves separated by reaction zone 15.  Inlet and outlet portions 17, 18 are each provided with a gas seal forming means 20 cylindrical and rectangular examples of which are shown in Figs. 6 and 7.  Sleeve chambers 21, 22 are located around the <PICT:0863219/IV(c)/1> <PICT:0863219/IV(c)/2> <PICT:0863219/IV(c)/3> whole of the periphery of inlet and outlet portions 17, 18 and inlet holes 23, 24 and slits 25, 26 permit passage of inert gas e.g. nitrogen or air supplied under pressure to the sleeve chamber and thence into inlet and outlet portions 17, 18 thus preventing escape of reaction gas e.g. acetic anhydridevapour.  Reaction zone 15 is provided with a device 31 e.g. a blower for circulating reaction gas which is exhausted through pipe 33 and re-enters through pipe 34, and slits 321 and 322 through which reaction gas is ejected on to the fibres to be treated.  Inlet 35 feeds reaction gas from a reaction gas generator while outlet 36 permits escape of waste reaction gas whereupon the latter is condensed, distilled and regenerated and returned to the generator.  Horizontal apparatuses (not shown) similar in construction to the vertical apparatus above are also described.

A pulse control system for a series-wound D.C. motor having reversing contactors 1, 2, for reversing the connections of the motor field winding E-F to the motor armature A-B, includes diodes D1 and D2 arranged so that one of the diodes is connected across both the field winding and armature to act as a freewheeling diode and the other diode is connected across the armature to act as a plugging diode when the system is operatively connected to the motor, irrespective of the direction of the connections of the field winding to the armature. A thyristor Th controlled by an amplifier V provides the pulse train, the pulse repetition frequency being controlled by a potentiometer 3 operable by the driving pedal of a light vehicle in which the motor is fitted, the D.C. source being a battery G1. Resistors R1, R2 in association with a diode D3 and a capacitor C constitute a filter element limiting the pulse rate during regenerative braking a transistor Tr providing the input for amplifier V. The voltage across filter element D3-R1-R2-C is then the forward voltage of that diode D1 or D2 connected across the armature. Alternatively, the filter element is connected to the terminals of a measuring resistor (not shown) in the motor circuit, the voltage across this resistor being proportional to armature voltage. The motor is braked until it stops and can then be made to build up speed in the reverse direction in conventional manner. To start regenerative braking contactor 2 is first changed over to its dotted line position and the contactor 1 is changed to its dotted line position.
