Title: Improvements in or relating to nuclear reactor fuel elements
Inventor: TAYLOR ALAN FREDERICK
IPC: G21C3/10
Filed: 1960-07-29
Abstract: 934,413. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 20, 1961 [June 29, 1960], No. 26599/60. Class 39 (4). [Also in Group XXII] A nuclear fuel element 1 comprises a thin sheath 3 of circular cross-section and end caps 5, 6, the side walls of which are also thin, which are welded in position when fitted in the sheath 3 by an interference fit created by a taper, preferably of 0.005 inch diameter per inch of length. In the example described, the end caps 5, 6 of stainless steel are sealed to the sheath 3, also of stainless steel, by argon-arc edge-welds 9, 10 backed up by circumferential resistance welds 11, 12. The fuel is in the form of a number of UO 2  ceramic pellets 2 each having chamfered ends 4 to provide lead-in surfaces when the pellets 2 are fed into the sheath 3, heat-insulating plugs 7, 8 of sintered alumina spacing the end caps 5, 6 from the pellets 2. Tne ends of the pellets 2 have flat rims and centrally disposed depressions 16 so that stresses set up in the sheath 3 with temperature changes in the fuel are governed by the temperature at the periphery of the depressions 16 where the pellets 2 contact one another. The external surface of the sheath 3 is provided with a series of circumferential ribs 13 which increase heat transfer and add strength to the sheath. The fuel element 1 is one of a number of similar fuel elements forming a cluster assembly and the ends of the sheath 3 have collars 14, 15 for location and support of the element by grids forming part of the assembly. The pellets 2 and plugs 7, 8 are loaded in a helium atmosphere into the sheath 3 which is closed by the lower end cap 6 and expanded by heating to allow easy loading. The helium atmosphere is maintained while the end cap 5 is fitted into the upper end of the sheath 3 and secured first by weld 11 and then by weld 9, weld 11 being tested for leakage before weld 9 is made. To test for overall leakage, the fuel element 1 is re-heated so that the small amount of helium retained in the sheath 3 expands and is then monitored with gas-detecting equipment for out-flowing helium. Helium contained in the sheath 3 improves the internal heat transfer properties of the element. As the element cools, the sheath 3 contracts about the pellets 2.

Abstract: 969,614. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. July 20, 1961 [Aug. 2, 1960], No. 26727/60. Heading H1K. A semi-conductor device, which produces a stepped current waveform in response to a continuously increasing voltage, comprises a base-plate 1 of semi-conductor material with main electrodes M spaced alternately on one side and the other so as to overlap, the spaces on each side of the base-plate between adjacent electrodes being subjected to the injection of carriers. The carriers are injected by means of the emitter electrodes E. The p-type electrodes are strips extending across the width of the high resistivity n-type base-plate 1 or may be sectors disposed in an arc as shown in Fig. 4. The emitters may be small electrodes placed in positions offset from the line of main electrodes; Fig. 3, not shown. The Provisional Specification refers to the injection of carriers by means of localized light beams. The main electrode M1 is connected to a potential negative with respect to a distant or central terminal F. As the potential difference increases, current drawn by terminal T1 stays at the saturation value corresponding to the size of the junction provided by electrode M1 until the voltage reaches the punch through valve from electrode M1 to electrode M2 and additional current is drawn by terminal T1 to the extent allowed by emitter El. When a further increase in voltage achieves the punch through valve from electrodes M2 to M3, the current is further increased by the amount contributed by emitter E2. The current is thereby increased step-wise as the base material punches through from electrode to electrode until M6, of Fig. 1, or M9, of Fig. 4, is reached.

Title: Process for preparing aqueous dispersions of lipid spherules and aqueous dispersions of such lipid spherules
IPC: C09K23/00
Filed: 1976-06-29
Abstract: The spherules have a diameter of 1000 to 50,000  ANGSTROM  and consist of molecular layers of lipid compounds whose molecule contains a hydrophilic ionic group and a lipophilic group. They contain an aqueous phase to be encapsulated, it being possible for this aqueous phase to contain dissolved substances with cosmetic, alimentary or pharmaceutical action. Such a dispersion is prepared, for example, by homogenising a mixture of sphingomyelin and of a glucose solution, by adding a solution of NaCl or KCl and vigorously agitating the whole. The spherules obtained have a diameter of approximately 2 microns and are therefore sufficiently large not to pass through the skin, and this is advantageous in the case of cosmetic applications.

Title: Improvements relating to the manufacture of structures produced by depositing fibrous elements
Inventor: CLARK JAMES D ARGAVILLE
IPC: B28B1/52
Filed: 1955-09-22
Abstract: 785,394. Making fibrous panels or boards &c. CHANGEWOOD CORPORATION. Sept. 22, 1955, No. 27121/55. Class 96. [Also in Groups IX, XXIII and XXX] Wood fragments, chopped straw or bagasse, or flax shives &c. are deposited in a uniform layer on a travelling belt &c. feeding the wood &c. into one end of a distributer, the other end of the distributer moving continually and successively into direct or indirect communication with separate conveyers at a rate to deliver substantially equal amounts of the elements to each, the conveyer outlets being positioned across and spaced above the collecting surface. The layer formed may be subsequently moulded into a panel or board by heat and pressure with or without a bonding agent. As shown, Fig. 1, fibrous material 10 on an endless belt 13 is fed by a picker 14 into a shoot 11 leading to a rotary distributer tube 12, driven by a motor 21, the outlet end 18 of which travels around a trough 20 delivering material successively to a series of down pipes 27 the outlets of which are disposed in two rows across the width of an endless belt, screen or lattice 32 on which the material forms into a layer 35. " Splash " plates 30 and directing troughs 33 are provided at the outlets of pipes 27 to control the deposition of the fibrous material; either the plates or the troughs may be adjustable for correcting non-uniformity of the layer 35. In an alternative arrangement, Fig. 5, a distributer pipe 40 is oscillated across the inlets of a row of down pipes 27a. The oscillation may be in simple harmonic motion or, as shown, at a more constant speed by means of an arm 44 pivoted to a constant speed chain 51. The size of the inlet openings to pipes 27a is in inverse proportion to the time of traverse of distributer 40 over the various openings, so that the amount of material entering each pipe 27a is substantially uniform. Picker 14, Fig. 1, may be replaced by a brush roller which provides an air flow along shoot 11 to assist the gravitational movement of the material; alternatively, a blower 70, Fig. 5, can supply air to shoot 11 and an exhaust fan 72 can withdraw air from beneath collecting surface 32 which is made foraminous. In a further alternative arrangement, Fig. 7, material is fed on to an endless belt 55 which is rotated as a whole about a shaft 57 so as to deliver material successively through openings 62 in a trough 63 to spouts 64 each of which delivers on to one of a series of conveyers 54 disposed across the width of collecting surface 32. Material is retained on conveyers 54 by side members 65 and is smoothed out by backwardly rotating rakes or brush rollers 67, and is doffed from conveyers 54 on to conveyer 32 by a further rotating brush. Conveyers 54 are moved at a much slower speed than conveyer 32. The delivery ends of conveyers 54 may be adjustable, as may the effective width of openings 62, for controlling uniformity of material deposition.
