Title: Improved nuclear reactor and method for refueling same
IPC: G21C19/20
Filed: 1965-08-10
Abstract: 1,106,792. Fuelling reactors. GENERAL DYNAMICS CORPORATION. 10 Aug., 1965 [13 Aug., 1964], No. 34155/65. Heading G6C. A gas-cooled reactor comprises fuel elements 23 forming a core 19 within a pressure vessel 18, these fuel elements being supported at their lower ends by pins 72 upstanding from a grid plate 69 and entering a hole in the elements. For purposes of re-fuelling, the fuel elements 23 are divided into zones, each zone having associated therewith a nozzle 27 extending through a biological shield 31 whereby the fuel elements may be withdrawn by a machine 45. The machine 45 (described in detail with reference to Fig. 7, not shown) is movable along rails 35 on the floor 34 of the reactor building 33 on to a bridge 38 movable on rails 37 transverse to the rails 35, whereby a nozzle at the lower end of the machine may be coupled to the selected nozzle 27 via a valved adaptor (93) previously put into position by an auxiliary hoist 41. Before the machine 45 can remove the fuel elements, however, the nozzle 27 must be emptied of a control rod drive mechanism 28 and two control rods 25 which are normally disposed therein and to this end a machine 43, also movable on the rails 35, is coupled to the adaptor (93). The machine 43 (described in detail with reference to Fig. 5, not shown) transports the mechanism 28 either to a storage well 47 or to a hot service facility 53. In each zone immediately beneath each nozzle 27 there are five fuel elements 23 and two guide tubes (83) (Fig. 4, not shown) for receiving the two control rods 25, these elements and guide tubes may thus be removed directly by a hoist in the machine 45, the grab being lowered down the nozzle and being aligned with a selected one of the elements or tubes by appropriate displace. ment of the hoist. The remaining fuel elements of the zone, however, must first be displaced laterally to be disposed beneath the nozzle before they can be withdrawn therethrough, this displacement being accomplished by an apparatus (57) (Fig. 8, not shown) similar to that disclosed in Specification 1,010,897. Thisapparatus is conveyed to the nozzle 27 from a well 47 by the machine 43 and is lowered into the core 19 to occupy the space vacated by the five fuel elements and two guide tubes. The apparatus (57) is displaced to engage a fuel element and lift it slightly so as to free it from the pin 72, whereupon the apparatus displaces the fuel element laterally to position it beneath the nozzle and finally the fuel element is raised into the machine 45. When six elements have been withdrawn the machine 45 transfers them to a storage vault 49. The arrangement enables the pressure vessel 18 to have a height less than twice the length of a fuel element. The vessel 18 is disposed in a cylindrical secondary containment vessel 29 having the shield 31, the heated gas from conduits 87 passing to steam generators 91 (Fig. 2, not shown).

Title: Improvements in and relating to centrifugal separators
IPC: B04B3/00
Filed: 1920-12-13
Abstract: 175,478. Sturgeon, R. A. Dec. 13, 1920. Right to Patent relinquished. Density separators.-In a centrifugal machine for separating solids from liquids, the liquid is fed through the hollow shaft 1 and tubes 7 to the annular space 6 between the cylinders 4, 5. The inner wall 5 of the space consists of a filtering- medium. Where the solids are heavier than the liquids, they are thrown against the wall 4 and the pressure developed centrifugally as the mixture travels through the tubes 7 causes a filter press action to take place and the liquid filters through the wall 5 to discharge through the holes 8. The feed into the annular space may be between two discs instead of through the tubes 7, and the discs may be formed of filtering-medium. The cylinder 4 can be removed for clearing the deposited solids. In a modification, the annular space is bounded by end walls and a conical portion, all of which are formed of filtering-material. In another modification the feed-pipe 18. Fig. 4, has a screwed stopper 19. A plunger 20 is thrown outwards by centrifugal force until the packing of the solids reaches a predetermined amount. The pressure then forces the plunger against the stopper and screws it to close the feed-pipe. In the self-discharging modification shown in Fig. 5, the upper cylinder 23 is secured to the hollow shaft 22 and the lower cylinder 24 which reciprocates in the upper one has mounted on it a piston 25 and contains a piston 26 fixed to the hollow spindle. Water admitted to the cylinder 23 forces the cylinder 24 downwards to make the joint 28. The liquor is then fed through the pipe 29 into the annular space 30. To discharge the solids, water is admitted through the tube 33 and the holes 34 into the space above the piston 26. This lifts the cylinder 24 and exposes the deposited solids, which are thrown into collecting-compartments. At the top of the movement of the cylinder the plate 37 and ring valve 36 are depressed. This allows the water above the piston 26 to escape and the cylinder descends to close the joint 28. Specification 24038/13 is referred to.

Abstract: 1,004,623. Cooling dynamo-electric machines. C. A. PARSONS & CO. Ltd. Oct. 27, 1961 [Oct. 18, 1960], No. 35638/60. Heading H2A. The rotor conductors 3 of a dynamo - electric machine have closed cooling circuits 4 formed therein, each circuit extending from a portion of a conductor located in a rotor slot 2 to a portion 3a located outside of the slot so that heat developed in the portions of the conductors outside the slots is removed by a cooling fluid circulating in the cooling circuits and given up by the cooling fluid to a coolant cooling the conductor portions in the rotor slots. Each of the cooling circuits 4 is formed by two longitudinal passages 4a, 4b connected at their ends by radial passages 4c, 4d and extends from a position adjacent line A-A midway along the rotor to a point adjacent the mid-point of the part of the conductors outside the rotor slots. The radial passages 4c, 4d may be formed by drilling and portions 4c<SP>1</SP>, 4d<SP>1</SP> plugged to ensure a closed circuit which contains a cooling fluid such as water, gas or vaporized liquid which circulates by virtue of the thermal syphon effect produced by the temperature difference between the part of the conductor 3a and the slot embedded portion and by rotational forces. The heat developed in the parts 3a of the conductors is thus transported by the cooling fluid in the closed circuits 4 to the slot embedded portions where it is removed by a coolant which enters the slots from channels 5 and flows radially outward between the conductors through a central radial passage 6. Part of the end portions 3a of the conductors may be displaced radially with respect to the slot embedded portions, in which case the closed cooling circuit may take the form of a single passage extending from the slot embedded portion to the end portion 3a.

Abstract: 977,188. Rod couplings. WAFIOS WAGNER, FICKER & SCHMID G.m.b.H., [trading as WAFIOS MASCHINENFABRIK WAGNER, FICKER & SCHMID]. Sept. 11, 1963 [Sept. 20, 1962], No. 35788/63. Heading F2G. [Also in Division B3] A process for clamping together rod-shaped metal parts, e.g. of a circular or square section lying one above the other, by means of a preformed sheet metal clamp, comprises at a first station using a known vertically reciprocating cutting and bending tool to sever a portion from a band and bend it about a mandrel to form a U-shaped clamp having arms of unequal length and at a second station pressing by a vertically reciprocating punch the web portion of the clamp on to the parts to be connected and the long arm against a second bending tool so that the relative movement between the punch and tool places the long arm about the parts and causes the free end of that arm to move into the path of a third bending tool which bends it completely against the side of parts gripped by the short arm of the clamp. Clamps 1 are severed by a bending tool 6 co-operating with a knife 8 from a strip 5 and formed about a mandrel 7 arranged below a table top 4 and subsequently pushed stepwise by a rod 9 along the mandrel 7 over a path 10 arranged transversely of the strip feed direction into a channel 11 which extends through the table having a vertically reciprocable punch 12. A second bending tool 13 having an upper concave surface 13 pivotally mounted on a shaft bears against one side of the punch, the tool being screwed to a fixed part of the apparatus when in operation, and a third bending tool 14 having a recess 14<SP>1</SP> is slidable along the other side of the punch. When the clamp has entered the channel it is raised by the punch 12 into contact with a frame part 3, manually positioned on the table, and above which is positioned the end of a spring 20 to be joined thereto, the punch is then further raised to effect bending of the long arm about the parts whilst the tool 14 overtakes the punch so that when the end of the leg emerges from the surface 131 it enters the recess 14<SP>1</SP>, at which point the tool 14 moves downwardly to bend the end over the parts or to overlap the short leg. To allow for this overlap and permit the flexing of the tool the rear portion thereof is relieved at 14". To compensate for parts of different heights a spring- loaded 21 toggle joint 22 bearing against a fixed part 23 is connected into the punch 12 drive. In a modification the punch 12 may be fixed and the tool 13 movable.
