Title: Nuclear reactors
IPC: G21C3/326
Filed: 1972-04-21
Abstract: 1422785 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 5 April 1973 [21 April 1972] 18704/72 Heading G6C A nuclear fuel element comprises an elongated outer cladding enclosing nuclear fuel in the form of a loose bed of fission product retaining fuel particles, there being an orifice at or near each end of the cladding so that the fuel is cooled by the flow of coolant in parallel over the outer surface of the cladding and through the fuel. A fuel assembly for a gas-cooled fast reactor incorporating such fuel elements comprises three clusters 20, 21, 22 arranged end to end between top and bottom end fittings 23, 24 within a shroud 25. The two end clusters 20, 22 are composed of fuel rods of canned fuel pellets of fertile material and are supported by upper and lower grids 26, 27, while the centre cluster 21 is composed of fuel elements of the abovedescribed construction which are supported between upper and lower grids 28, 29. Voids V 1 , V 2  are provided between the grids 27, 28 and 26, 29. Each fuel element comprises a cladding 1 containing superimposed layers of nuclear fuel spheroids 40 having fission product retaining coatings, the cladding 1 being closed at each end by porous plugs 30 each having a dowel 31 extending from its centre. The dowels 31 are a sliding fit in holes 32 in the grids 28, 29. Other holes 32a, 32b permit the free flow of coolant in stream A over the outer surfaces of the claddings 1 and in stream B through the gas-permeable fuel. The external faces of the fuel elements have spacer pads 35 which abut one another to maintain channels 34 through which the stream A passes. The coolant enters the fuel assembly through an orifice 24a in the lower end fitting 24 and leaves through apertures 236 in a block of neutron-reflecting material forming the upper end fitting 23. The fertile fuel region may be extended into the end regions of cluster 21 by substituting coated fertile fuel spheroids for some of the fissile fuel in the end portions of the fuel elements of the cluster 21. The claddings 1 may be provided with a taper so that coolant channels 34 are formed which are divergent in the coolant flow direction. If desired, one or more baffles (as at 7, Fig. 1, not shown) may be mounted within the mass of spheroids to encourage outward movement of coolant.

Title: A method of and apparatus for cleaning substantially flat ceramic waref
IPC: B28B11/22
Filed: 1964-05-05
Abstract: 1,063,017. Cleaning ceramic ware. JOHNSON BROS (HANLEY) Ltd. and G. W. BIRD. Aug. 5, 1965 [May 5, 1964], No. 18714/64. Heading A4F. [Also in Division B8] In a method of cleaning articles of substantially flat ceramic ware, e.g. plates and saucers, the ware is moved mechanically article by article from a stack on to a moving conveyer to be carried past a cleaning station where the ware is cleaned, and is subsequently mechanically deposited to form a second stack. In the method particularly described a stack of ware is placed horizontally on parallel conveyer belts (13a, 13b, Fig. 2B, not shown) with the rear article of ware resting against an inclined support (21) which moves with the belts. The plates or saucers are fed singly from the belts (13a, 13b) by a toothed wheel (28) which engages the bottom edge of the leading article and passes it face downwards on to a pair of faster moving belts (15a, 15b) which transfers the ware to a further pair of fast moving belts (14b, 14c). These carry the articles over circular brushes (35, 36, Fig. 3A not shown) which rotate in opposite directions about a horizontal axis to clean the faces of the plates, the rear sides then being cleaned by a chain brush (43). The ware is discharged from the belts (14b, 14c) by a compartmented transfer wheel (48b, Figs. 4A and 4B, not shown) to form a horizontal stack in a trolley (49) running on rails (62). Alternatively the ware is fed to the trolley (49) via an inclined shoot (72, Figs. 5A and 5B, not shown).

Abstract: The invention comprises monoazo compounds of the formula <FORM:0786908/IV (b)/1> wherein A stands for a benzene nucleus substituted by at least one sulphonic group and optionally carrying at least one chlorine, bromine, cyano, -COOalkyl, -COOH, -SO2 alkyl, -COC6H5, or -CONRR1 substituent, where R and R1 stand for hydrogen, alkyl, cycloalkyl, aryl, or aralkyl and, in addition, alkyl up to 4 carbon atoms and Y is -CN, -COCH3, or -CONH2.  They are made by diazotizing an amine A-NH2 and coupling with malonitrile, cyanacetamide or diacetonitrile.  The products have ultra-violet absorption properties.  Aromatic amines A.NH2 specified are orthanilic, metanilic, and sulphanilic acids, aniline - 2,5 - disulphonic acid, 4 - chlor - aniline - 3 - sulphonic acid, 5 - sulphoanthranilic acid, and 2-chloro-4-toluidine-5-sulphonic acid and isomers thereof.  When diacetonitrile is used as coupling component, it is sometimes necessary to decompose an intermediate of the formula <FORM:0786908/IV (b)/2> by heating with ethanol containing hydrochloric acid.  In examples, aniline 2,5-disulphonic acid is diazotized and coupled with cyanoacetamide and diacetonitrile.ALSO:The invention comprises monoazo compounds of the formula: <FORM:0786908/IV (b)/1> wherein A stands for a benzene nucleus substituted by at least one sulphonic group and optionally carrying at least one chlorine, bromine, cyano, -COO-alkyl, -COOH, -SO2-alkyl, -COC6H5, and -CONRR1 substituent when R and R1 stand for hydrogen, alkyl, cycloalkyl, aryl, or aralkyl, and in addition, up to 4 carbon atoms, and Y is -CN, -COCH3, or -CONH2.
