Title: Fuel assembly for nuclear reactors
Inventor: GUMUCHIAN ANDRE
IPC: G21C3/326
Filed: 1967-11-27
Abstract: 1,139,968. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 27 Nov., 1967 [5 Dec., 1966], No. 53771/67. Heading G6C. A nuclear fuel assembly comprises, within a coolant circulation duct, a bundle of fuel pins each comprising a can of which one portion is loaded with fissile material and another portion constitutes an expansion chamber, those portions of the cans loaded with fissile material being at the same level within the duct, and the fuel pins being arranged in two sections in which the expansion chambers are disposed at different levels in the duct. The assembly for use in a fast reactor, shown in Figs. 1 and 2, comprises a central bundle of pins loaded with fissile material disposed within a duct 16 of hexagonal cross-section between a top bundle 12 and a bottom bundle 14 of pins loaded with fertile material. The fuel and the expansion chamber portions of the pins of the central bundle are separated by racks 42 in the pin cladding. A first section 10a of the central bundle occupies the centre of the bundle and has a cross-sectional area corresponding to that of a central passageway left free by the top and bottom bundles 12, 14. This section is composed of pins whose expansion chambers are located above the fuel portions. In order to permit of free expansion, the pins of the section 10a are simply guided by the pins of the second section 10b and by the pins of the top bundle 12, being suspended from a lifting head 22 at their upper ends whilst their lower ends are left free. The second section 10b is made up of the remainder of the pins of the central bundle and the expansion chambers of this section are placed beneath the fuel portions. These pins are suspended from a grid 32 and guided at their lower ends by a grid 36. The coolant is admitted in the direction of the arrows f through an inlet 20 in a bottom end-fitting 18 and the greater part passes upwardly along an axial portion delimited by the pins of the bottom bundle 14 and the expansion chambers of the bundle section 10b, thus by-passing the bottom bundle and the expansion chambers from which only a relatively small amount of heat is released. The flow is then distributed between the necked portions of the section 10b and cools in a uniform manner the fuel portions of both sections 10a, 10b. At the level of the grid 32, the greater part of the flow escapes laterally into the top bundle 12 which, by reason of the larger diameter of the top bundle pins, affords a lower pressure drop coefficient than the section 10a of the central bundle.

Patent GB-539280-A (GB)
Abstract: 539,280. Yarns. BRITISH CELANESE, Ltd. March 2, 1940, No. 3943. Convention date, March 2, 1939. [Class 120 (iii)] A yarn having staple fibre characteristics is made from a continuous filament yarn by drawing it longitudinally past a rotating cutting element and giving the yarn a rotating motion about the cutting element, whereby the yarn forms a balloon surrounding the cutting element, and a radial oscillating motion towards and away from the cutting element. As shown the cutting element is in the form of an abrasive disc 15 resting on a seat 14 on the end of the ring spinning spindle 13 and rotated thereby ; a loose ring 18 is disposed between the disc and a nut 17 screwed in the end of the spindle and a cardboard or other disc 19 may be placed on top of the disc 15 to prevent the ring 18 contacting with the disc 15. The yarn passes from the supply through the ring 18 and over the flange 21 of the bobbin 12, or a disc 22 therein, to the ring 9 and as the yarn rotates around the disc 15, it is given a radially oscillating motion towards and away from the disc by the motion of the loose ring 18. In a modification the loose ring 18 is dispensed with and the yarn passes inside a pair of rings carried by the machine frame and disposed concentrically with the spindle and one above and one below the abrasive disc ; in this case the radial motion of the yarn arises from the variation in yarn tension during the traversing of the yarn on the bobbin. The abrasive disc may be fitted with vanes against which a blast of air is directed to cause the rotation of the disc with or counter to the rotation of the spindle. In an up twist arrangement the yarn from the delivery bobbin passes through the eye of a flyer freely rotatable on the flange of the bobbin and over the edge of the abrasive disc to the freely rotatable ring before passing to the take-up package. The bobbin spindle may be hollow and the abrasive disc carried by a spindle passing through the bobbin spindle and driven at a speed different from that of the bobbin spindle ; the spindle carrying the abrasive disc may also be given a reciprocating motion.

Apparatus for the production of ceramic mouldings, e.g. handles, includes a mould wheel 2 carrying moulds 3 and rotated stepwise past a station 6 where the moulds are charged, a station 9 where mould material is cut-off from the mould, a station 10 where the moulding is removed from the mould, and a station 12 where the emptied mould is cleaned. At the station 6 a predetermined length of porcelain paste is extruded from a cylinder 7 and received by a slit-tube 31 which is then driven downwardly thereby separating the paste piece from the remainder and aligning it with a ram 33. Before the ram is moved forward, a slide 36 carrying a paste-receiving chamber 39 with an injection nozzle 41 has been moved forward to abut a mould; the ram then forces the paste into the chamber and through the injection nozzle into the mould, any surplus being extruded through an overflow aperture 42. The device 8 which moves the slit tube downwardly is linked by a cable 43 with a carriage which carries a cutter 45 so that the downward movement causes the cutter to remove mould projecting parts. At the extraction station the mould halves are opened and the moulding removed by extraction needles which pass through a split conveying belt and pierce the moulding which is removed therefrom by the belt. The opened and emptied moulds are cleaned by a brush moistened with cleaning liquid. Direct voltage impulses are applied to the mould to effect detachment of the moulded article before its removal.
