Abstract: A refuelling system suitable for use with an overwing fuelled aircraft comprising: (b) a stored fuel grade identification means for identifying the fuel grade stored in the fuel storage vessel and available type(s) of delivery of the fuel to the aircraft; (d) an aircraft fuel grade identification means being attached to, or forming part of, an overwing fuelled aircraft, wherein said aircraft fuel grade identification means represents the fuel grade requirement of the aircraft and is readable from the exterior of the aircraft; (g) a transmission and receiving system which enables information regarding the fuel grade that had previously been supplied to the aircraft having the aircraft registration number inputted into the computer interface and the type of delivery of fuel which may be used by said aircraft to be retrieved from a remote database; (i) an automated cross-check system which is configured to retrieve the fuel grades identified by the fuel identification means in (b), retrieve the fuel grade identi

Abstract: A magnetic filter carriage (16) for use in filtering contaminants from fluid in a high pressure fluid flow comprises a frame (18, 20, 22) arranged to support a plurality of magnet filter rods (42), such that the rods (42) are each supported at both ends thereof in a fixed orientation, for example parallel to one another. The frame (18, 20, 22) is adapted to be inserted within a pressure vessel (4) across the direction of fluid flow between a fluid inlet (7) and a fluid outlet (9) of the pressure vessel (4), and may be arranged such that more than about 90% of the flow across the vessel (4) passes through the frame (18, 20, 22). The rods (42) are mounted in a plurality of cassettes (36) which are easily removable for cleaning or replacement.

Abstract: A flow distributor for a fluid flow entering a deceleration vessel from an inlet conduit comprises a plurality of spaced vanes arranged extending substantially parallel to each other across a width of the distributor and being angled from the upstream to the downstream end so as to form flow channels therebetween to direct flow outwardly away from a central portion of the distributor.
