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 identified in (d) from the hand-held device, retrieve the type(s) of delivery of fuel identified by the fuel identification means in (b) and by the system of element (g), and the previous fuel grade supplied to the aircraft identified by the system in element (g) which can generate a positive response signal if all of the fuel grades identified are compatible with each other and the type(s) of delivery of fuel to the aircraft are compatible.
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.
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.

A viewing system (20, 22) for inspecting an interior portion of a fluid vessel (4), such as a magnetic filter vessel, comprises a fluid tight tube extending through a wall of the vessel (4) from a proximal (24) to a distal (28) end of the tube, the tube being arranged to carry optical fibres and being provided with a transparent window (30) at the distal end (28) thereof. A further tube can be provided for carrying a camera. The tubes can be positioned spaced apart and adjacent the magnetic filter (16) for visually inspecting the filter.
A tray arranged to fit into the base of a pressure vessel having a sump opening, the tray at least partially formed of a fluid permeable mesh material and having an upstanding wall suriOunding an opening arranged to coincide with the sump opening, the wall being adapted for containing particles in the tray. Thus particles falling to the bottom of the vessel may be collected in the tray for disposal.
