Title: Improvements in or relating to fuel materials for nuclear reactors
Inventor: NORREYS JOHN JEPHSON
IPC: G21C3/62
Filed: 1963-11-07
Abstract: 1,011,053. Nuclear fuel materials. GENERAL ELECTRIC CO. Ltd. Oct. 23, 1964 [Nov. 7, 1963], No. 43991/63. Heading G6C. A nuclear fuel material consists substantially of uranium carbide having a composition in the range of 50% uranium : 50% carbon to 48% uranium : 52% carbon, in atomic percentages, and tungsten in a proportion in the range of 0À05 to 5À0% by weight of the weight of the material. The addition of tungsten in the above proportions is found to produce a marked increase in the creep resistance of uranium monocarbide. The term "substantially" is used above since minor amounts of impurities may accidentally be introduced either in the starting material or during the manufacturing process. The fuel material is preferably manufactured by arc melting a mixture of uranium, carbon and tungsten in the required relative proportions, the molten mass produced being cast to form a body of a desired shape and size. The tungsten can be introduced by using a tungsten electrode for the arc melting of the uranium-carbon mixture; however, it is preferred to use a graphite electrode and to add the required amount of tungsten initially to the uranium-carbon mixture, since the proportion of tungsten introduced can be controlled more precisely in this way. As an alternative to a mixture of uranium and carbon preformed uranium monocarbide of the required composition can be used as the starting material. Another method of manufacturing the fuel material comprises pressing a powdered mixture of uranium, carbon and tungsten, or of uranium monocarbide and tungsten, in the required proportions, to form a compact of a desired shape and size, and sintering the compact. The cast or sintered bodies of fuel material may, if desired, be subjected to an annealing heat treatment.

Title: Regeneration of absorbents
IPC: B01J20/00
Filed: 1961-12-12
Abstract: A process for regenerating an adsorbent bed which has been deactivated by, for example, dehydration of a hydrocarbon comprises contacting said adsorbent with a liquid hydrocarbon diluent inert to said hydrocarbon to remove residual amounts of said hydrocarbon, contacting said adsorbent with said diluent in a superheated and vaporized state, and thereafter contacting said adsorbent with said diluent in the liquid state to cool said adsorbent.  The diluent may itself be dried by an adsorbent bed subsequently regenerated by the aforementioned process, and the hydrocarbon to be dried and the regenerating diluent may therefore be the same.  Prior to contacting the adsorbent bed with superheated diluent vapour, residual diluent in the bed may be removed by purging with nitrogen.  The hydrocarbon to be dried may be a conjugated diene subsequently polymerized in the presence of said liquid diluent.  Diluents specified are paraffins, cycloparaffins, aromatics, or any mixtures thereof, in particular propane, butane, iso-octane, cyclohexane, methyl-cyclohexane, benzene and toluene.  Adsorbents specified are bauxite, activated alumina and silica gel.  The adsorbent is preferably contacted with the diluent vapour at 250 DEG  to 600 DEG F., and subsequently cooled to 32 DEG to 150 DEG F.  An example relates to the dehydration of 1,3 butadiene in an alumina bed regenerated using a toluene as the diluent.

Abstract: 1,091,529. Packaging-machines; feeding material. F. UTTLEY & SON Ltd. Feb. 14, 1966 [Nov. 14, 1964], No. 46461/64. Headings B8C and B8S. Fibrous material is fed between the nip of two conveyer bands 2, 3, Fig. 1, from an associated hopper 21 into a bag 19 supported in a wheeled carriage 18. When the bag is full, the carriage is removed by friction between one band 3 and the material, while the other band 2 is pivoted away from the mouth of the bag. In the embodiment, when the bag is completely full and the pressure of the material in the bag against the conveyer band 2 reaches a predetermined level, this band is pivoted away in a direction A about an axis 12. The upward movement of the band 2 actuates a microswitch 16 causing a lamp 22 to be illuminated, indicating to the operator that latches 20, retaining the carriage in position below the hopper, should be released. With the band 2 moved out of contact with the filling material and the latches released, friction between the band 3 and the filling material causes the carriage and filled bag to be removed in the direction B. As the carriage moves out of the device, a flap (19A), Fig. 3 (not shown), previously positioned over a stationary bar (25), is automatically caused to cover the mouth of the bag, freely rotatable rollers 17 holding the cover over the bag, which is then closed by lacing, skewering &c., the cover on to the bag mouth. in a modification, the rollers 17 may be replaced by an endless band and the bands 2, 3 may be engaged round three drums (12), (12A) and (26), Fig. 4 (not shown), instead of two as in Fig. 1.

Abstract: 1453494 Welding by fusion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 Oct 1974 [31 Oct 1973] 46561/74 Heading B3R In plasma-MIG arc welding wherein a consumable electrode 13 is fed coaxially through a water-cooled, copper, plasma gas nozzle 7 and a metal arc is struck between said consumable electrode and a workpiece 15 in a plasma arc between said nozzle (acting as a non-consumable electrode) and said workpiece, said plasma arc, emanates from an inner surface 37 defining an orifice 9 of the nozzle. As shown, the consumable electrode 13 is fed by adjustable speed motor driven rollers 17 through a contact tube 11 accommodated, by way of an insulating cap 12, in a housing 5 provided with the nozzle 7. The nozzle is cooled by water in chambers 27 fed via duets 29. Plasma gas, e.g. argon, is fed to the nozzle through a pipe 21 and the housing. Shielding gas, e.g. a mixture of argon and carbon dioxide, is fed to a hood 23 surrounding the nozzle. The consumable electrode and the nozzle have the same polarity and are connected to separate current sources, respectively a source 43 having a flat output characteristic and a source 47 having a drooping output characteristic. In operation, the plasma arc is spontaneously struck by striking of the metal arc by consumable electrode/workpiece contacting. Electromagnetic force derived from currents in the consumable electrode draws the plasma arc radially inwards and along so as to be attached to the inner surface 37 of the nozzle. Increased bore diameter of the nozzle upstream of the orifice and restricted axial width of the surface 37 prevents arc climbing and fusing of the contact tube.

Abstract: 1378011 Gyratory crushers L W JOHNSON 12 Oct 1972 [27 Dec 1971] 47150/72 Heading B2A A gyratory crusher comprises a base frame 11 supporting a crusher head 13, Fig. 1. A V- shaped support ring 33 is bolted to a flange 37 of the frame 11. The top surface of the ring 33 is shaped as a guideway for a bowl carrier 41, which comprises a nut with internal threads 43 engaging male threads 45 of a segmented adjustment ring 47. The segments fit in notches in a bowl 49 Fig. 1A. A bowl liner 51 is suspended below the bowl 49 by rods 53. Wedges 63 are urged by double-acting rams 65 and spring thrust units 67, Fig. 5 to expand the segmented ring 47 and lock the bowl 49 relative to the bowl carrier. The rams 65 each include rods 80 which project upwards against beams 82 and downward against the wedges 63, Fig. 4. Screws 86 bolt the cylinders 65 to a flange 75 to tape the upward thrust. To adjust the bowl clearance 85, Fig. 1, a mechanism 90, Fig. 6, comprising a double-ended pawl cooperates with projections 95 around the periphery of a cover 97 attached to the bowl 49. The pawl is pivotally mounted to a bell crank lever 101 which is in turn pivoted on a pin 103 and actuated by a booster cylinder 109, Fig. 12. To adjust the bowl clearance 85, Fig. 1, pistons 78, Fig. 10 (rams 65) are retracted drawing up the wedges 63 and releasing the bowl 49. The mechanism 90 is then actuated to reciprocate the pawl 93, rotate the cover 97 and raise or lower the bowl. Upward/downward selection is by operation of solenoids 130, Fig. 6, which set the pawl 93 in appropriate position. After this the bowl is again locked in position. The mechanism 90 can be operated manually (by a lever 124, Fig. 6), with hydraulic assistance or electrically either locally or remotely. In this case a solenoid 130 sets the pawl in desired position and solenoids 128 are alternately energized to swing arm 116 against valves 120 causing the cylinder 109 to reciprocate the pawl 93. When adjustment is complete the pawl 93 is swung clear of the projections 95. The bowl carrier is held against the support ring 33 by a hold-down ring 111 which has a vertical flange 113 connected by rods 115 to cylinder brackets 118 which carry the rods of cylinders 121 Figs. 1, 1A. These cylinders permit the upper assembly (including bowl carrier 41) to lift when tramp material enters the crusher. Charged accumulators 127 maintain pressure in the cylinders to draw down the ring 111. The bowl 41 is permitted to creep under the large forces encountered i.e. to slide under the hold-down ring 111 and migrate round the ring 33 due to the provision of non-metallic rings 129, 131, Fig. I and 4. A machined surface 150, Fig. 1A, of the mantle 91 is clamped against the crusher head by a member 152 screwed into a socket 154 Fig. 1A which in turn is screwed to the head. A cap 158 is screwed to the member 152. The mantle is thus replaceable.

The area of impingement of an arc on the surface of a body to be heated is increased by the application of an alternating magnetic field. An inert gas-shielded arc of high current density from a tungsten or carbon electrode is employed, to reduce instability, the area of impingement of the arc being adjusted by adjustment of the magnetic field intensity, arc current, or arc length, and the temperature of the surface being controlled by varying the arc current, the oscillation frequency, or the speed of movement of the arc along the surface. The method is applicable to the heating of a metal surface before or after welding, and to surface-hardening.
