Title: Improvements in and relating to centrifugal moulding machines
IPC: B28B21/26
Filed: 1930-11-05
Abstract: 361,579. Moulding pipes in centrifugal moulds. DODD, E. V., 89, Church Street, Greenwich, London. Nov. 5, 1930, No. 33267. [Class 87 (ii).] A centrifugal moulding machine for pipes is provided with a movable core which is arranged to bear upon the top of the material and be lifted by it as the moulding progresses, thus assisting in consolidating it. In the illustrated form, material from the shoot 18 runs into the mould 6 supported on the rotating table I. The core 13 supported from the guided head 14 is partially counterweighted at 19 or loaded in accordance with the pressure it is desired to apply to the material. Projecting members 16, at the upper end of the core, are hinged to press upon the upper surface of the concrete and are lifted to raise the core by the rising level of the concrete as the operation proceeds. The bearing portion 17 of the members 16 is of arcuate shape as shown in plan in Fig. 6, and may be.shaped so as to mould a socket at the upper end of the pipe after the core has ceased to rise.

Abstract: 884,070. Gas seals for floating roof tanks. CHICAGO BRIDGE & IRON CO. Sept. 28, 1960 [Dec. 15, 1959], No. 33273/60. Class 69 (1). A floating-roof tank has a removable seal device in the annular space between the roof 11 and the tank wall 10 comprising a gas-inflated annular tube 13 removably secured to the roof by a connector. The tube is of vapourimpervious flexible material, vulcanized or impregnated with polyurethane, of integral construction or built up from more than one piece. It is suspended by lugs 14 and 15 formed from, or fixed on to, the material of the wall of the tube. The lugs may both be fixed only to a spaced series of upper connectors 21 hanging from the top of the roof (Fig. 1, not shown), or lugs 14 may be posed to a set of upper connectors 21 and lugs 15 to lower connectors 23-24, hitched removably under the floor 26 of the roof at 25. In both these instances hoops 16 and 17 extending circumferentially round the roof assist in clamping the lugs to the connectors. In other embodiments a metal plate may replace the fabric at 33 to form the inner wall of the ring and the edges of the fabric be modified to form efficient gas seals therewith (Figs. 5 to 8, not shown); or the fabric wall 33 may be continued upwards externally over the connectors to be clamped to the roof at 19 (Fig. 9, not shown).

Packing in a rotating or reciprocating piston 2 or piston rod or in the guide surface for the piston rod comprises a plurality of thin splitrings 5 pressed radially by the fluid in the cylinder, a resilient annular sealing body 6 behind the rings and a valve 12 allowing access of the operating fluid in the cylinder, only at the highest operating pressures, to the body 6 to press the rings 5 against their co-operating bearing surface. As applied to packing the piston 2, the rings 5 may be spring rings guided between slit rings 4 of cast-iron and seated on a body 6 of a substance like rubber or of thin resilient metal if the operating fluid is a hot gas. The bearing pressure of the rings may be increased by a leaf-spring 9 of oil-gas and acidproof material, or by pre-stressing the sealing body 6. One or more piston rings in separate grooves may be provided in front of the packet of rings 4, 5 to reduce the pressure of the operating fluid on the outside of the rings 4, 5. At least one ring 13, preferably of rubber, rubber-like material or leather, may be located behind the rings 4, 5 to strip particles of oil and dirt from the cylinder and effect initial sealing during running-in of the rings 5 which may be ground and lapped on the flat -surfaces. In a modification, the sealing body 6 and rings 13 are of rectangular section.

A device for varying the lattice of fuel and reflector elements in a nuclear reactor comprises two sets of guide bars disposed at rightangles to each other in two superposed planes, said bars each comprising two parallel portions having a space therebetween, and including fuel or reflector element supporting carriages slidably supported by one of the sets and engaged into the spaces of the other set. Each set of bars is linked by lazy tongs through pivots 10. The two bars 10 which cross at the centre of the lattice are in fixed positions,the lattice spacing being varied by moving the bars on either side of the fixed position bars towards or away from the centre. Bar movement is effected by motors 30, 31 rotating four leadscrews (only two shown) 26, 27 which expand and contract the lazy tongs through levers 24 which are restrained against rotation by a guide bar 36. The upper set of bars is supported by rollers mounted on their ends, which run on channel section beams 8. The lower set of bars is similarly supported on an I-section beam 9. The element support carriages are located by both bars forming a given lattice space but their weight and the weight of the elements mounted thereon is taken solely by the lower set of bars. They are spaced from the surrounding locating faces of the bars by spring plungers mounted on the carriages. The reactor core area is indicated by the line 5, and the bars beyond this area, including those that do not cross-bars of the other set, are for supporting reflector elements.
