Filed: 1975-08-12
Abstract: 1506887 Settling tank DORR - OLIVER INC 12 Aug 1975 [12 Aug 1974] 33513/75 Heading B1D A circular settling tank has a central annular sump and a rotary rake arm structure carrying blades which move settled sludge into and round the sump to discharge point(s) (Fig. 1, not shown), the blades being arranged to induce a downward flow of supernatent liquid to around their leading edges to fluidise the sludge locally and thus reduce the torque on the rake arm structure. The rake arm structure may be driven from its central supporting cage or may be pulled round by a trolley running along the tank periphery. In Figs. 3, 10 the inner sets of tank floorengaging blades 28, 36 have lower portions 30 curved in the direction of movement to lift the sludge creating suction which causes supernatent liquid to flow down the backs of the blades. Angle irons or open-ended pipes on the backs of the blades and extending above their upper edges may facilitate such flow. Fig. 3 shows how inner blades 28 are also curved in the horizontal direction, intermediate blades 36 are straight horizontally but curved vertically similarly to blades 41 where the sludge bed is thinnest, are simple planar. The blades (26) which move the sludge round the sump, to two or three locations from which pumps (Fig. 13 not shown) in a chamber beneath the tank remove it, are also curved in the vertical plane similarly to blades 28. The sump blades are mounted on the four lower corners of the central cage (14) of the rake arm structure and contoured to fit the sump. Figs. 12-19 (not shown) illustrate two constructions of sump blade one having an enclosed conduit and one having a rearwardly directed channel to facilitate flow of liquid down its rear face.

Title: Roadstone
IPC: C04B35/44
Filed: 1973-07-17
Abstract: 1488656 Artificial store ALBRIGHT & WILSON Ltd 27 Aug 1974 [17 July 1973] 33968/73 Heading ClJ A granular roadstone consists of a sintered mixture of up to 75% by weight of a spinel material, from 20 to 45% by weight of an uncalcined clay and from 1 to 10% by weight of a precalcined aluminosilicate which has been calcined at at least 800‹ C. The spinel material is any mineral having the spinel crystal structure and a formula corresponding to MgAl 2 O 4  wherein Mg and Al may be replaced at least partially by equivalent di- and trivalent metals respectively. A typical spinel has the formula (Mg 1-x Fe x )(Al 1-y Cr y ) 2 O 4  where x and y are between 0 and 1. An example of such a spinel is chrome ore or the residue from the chemical extraction of chromates from chrome ore. The uncalcined clay is any natural earthy or strong material consisting essentially of hydrous silicates and alumina; suitable clays are kaolin, china clay, ball clay, fire clay, stoneware clay and bentonite. The precalcined aluminosilicate may be furnace brick, firebrick grog or a material obtained by heating sillimanite, andalusite or kyanite at from 1370‹ to 1545‹ C. and preferably consists at least partially of mullite. The mixed ingredients in powder form may be heated to sintering temperature in a static kiln or in a bed on a moving grate. Alternatively the mixture may be moistened or mixed to a paste with water, formed into pellets or granules by extrusion, moist granulation and drying and then calcined. A pumpable slurry of the mixture in water may alternatively be heated directly in a rotary kiln. The moist mixture may alternatively be formed into bricks, baked, subdivided and then crushed. Combustible materials such as coke may be included in the mixture so as to provide an internal source of heating during calcination, but it is preferred to calcine a mixture which contains insufficient combustible material to provide self-sustaining combustion. The frictional and wear-resistant properties of the roadstones may be improved by subsequent recalcination at a lower temperature than that used in their formation. The roadstone material may also be used to provide a sintered coating on the surface of a granular refractory substrate.

Title: Improvements in or relating to nuclear reactor fuel elements
Inventor: BLAKE LESLIE REGINALD
IPC: G21C3/17
Filed: 1960-10-04
Abstract: 925,426. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 28, 1961 [Oct. 4, 1960], No. 33973/60. Addition to 923,343. Class 39 (4). A sheathed fuel element for a nuclear reactor, such as a fast reactor, is filled with fuel to between 50 and 90% of the available fuel volume and has an outer sheath with a crosssectional shape having flats which are in direct contact with an inner sheath, the clearance elsewhere between the sheaths being filled with a thermally bonding material. The elements shown by way of example in Figs. 1 and 2 comprise a string of cylindrical sheathed fuel sections 11, 12, 13 encased in a common outer sheath 14. In the case of the element shown in Fig. 1, the inner sheaths 19 of the fuel sections are swaged over the rounded ends of end plugs 20a, 20b and intermediate the ends the sheaths are formed with necks where they are swaged over plugs 21 of porous stainless steel. Each plug 21 separates a fuel space 22 from a gas collection space 23, the latter being about 30% of the total volume of the two spaces. The fuel space 22 is filled almost completely by a ceramic fuel, namely a mixture of uranium and plutonium oxides packed at 80 to 95% of the theoretical density for the mixture. In the case of the element shown in Fig. 2, the space between the end plugs 20a, 20b is filled almost completely with a cermet fuel 24 which is a mixture of uranium and plutonium oxides dispersed in a uranium metal diluent of internal porosity sufficient to give an overall voidage of about 25% of the available fuel volume. Both the illustrated elements have a filling of a material of good thermal conductivity between the outer sheath 14 and the inner sheaths 19. Sodium, indicated at 25, is used in Fig. 2 since by confining the porosity to below the surface of the fuel the possibility can be avoided that the sodium, on gaining access to the fuel through defective sheathing, is caused by boiling at the high fuel temperature to set up additional internal pressures. In Fig. 1, the thermal bond material 26 is chosen to remain solid at the operating temperature and to have weak mechanical properties, e.g. copper or brazing metals, including palladium brazes. A fuel assembly made up with elements such as those described above is shown in Fig. 3, the outer sheaths 14 being flattened on four sides to give direct contact with the sheathed fuel sections and provided with radially projecting longitudinal ribs 15, 16, 17, 18 which engage one another and a sheet metal liner 28 interposed between the peripheral elements and a casing 27. On its outwardly-facing side, the liner 28 has similar ribs 29 spaced midway between each pair of ribs on adjacent elements.
