Abstract: A device for washing or treating the feet and lower legs of a user comprises an outer housing; a base assembly located in the outer housing; access means for providing access to a base assembly, a controller for controlling operation of the device, and a fluid supply mechanism. The base assembly includes a pair of footrests for supporting the feet and lower legs of a user during washing or treating, at least one rotatable transversely extending cleaning or treating assembly located above the footrest for washing or treating a user's feet; and a plurality of rotatable upright cleaning or treating assemblies for washing or treating the lower legs of the user. A ilting assembly is provided for tilting the base assembly relative to the outer housing through a plurality of inclined positions.

Abstract: A device for washing the feet and lower legs of a user comprises a tub for receiving the feet and lower legs of the user; at least one footrest located within the tub for supporting the feet of a user during washing; a fluid supply mechanism for introducing fluid into the tub; one or more rotatable transversely extending cleaning assemblies located above the footrest for washing a user's feet; and one or more rotatable upright cleaning assemblies communicating with the fluid supply mechanism for washing one or both lower legs of the user, wherein each rotatable upright cleaning assembly is carried on a guiding mechanism for moving the one or more rotatable upright cleaning assemblies around a portion of the footrest during a lower leg and foot cleaning cycle.

Abstract: The present invention relates to a system for contaminant extraction in a borehole extending from a surface of the Earth through a water permeable layer and into an underlying production zone, the system comprising: an outer casing located within the borehole and extending through the water permeable layer; a production pipe located within the casing and extending towards the production zone; a filter assembly occupying at least part of an intermediate zone between the outer casing and the production pipe, wherein the filter assembly is configured to capture contaminants before they enter the water permeable layer and/or before they are released into the atmosphere, the filter assembly comprising: a lower solids filtering stage configured to filter solid contaminants; and an upper fluids filtering stage configured to filter fluid contaminants migrating from the production zone through the lower solids filtering stage; and sealing means for preventing the uncontrolled leakage of contaminants from the intermedi

Abstract: The present invention relates to system and method for extracting shale gas through a bore hole located within a geological area. The system and method comprises a production pipe surrounded by a filter assembly, where the production pipe passes through different geological layers, such as a water permeable layer above an underlying shale layer. During extraction of gas from the shale layer, the filter assembly can capture and filter out any contaminants that are released before they enter the water permeable layer. The filter assembly includes lower expandable bell and a stacked arrangement of filters. A vacuum may be used to encourage filtration.

Abstract: An aircraft (10) comprising a fuselage (12) having an upper pilotable fuselage portion (10A) and a lower jettisonable fuselage portion (10B), the lower jettisonable fuselage portion (10B) being detachably engaged with the upper pilotable fuselage portion (10A) during normal flight. An upper wing structure (14A) is associated with the upper pilotable fuselage portion (10A) and a lower wing structure (14B) is associated with the lower jettisonable fuselage portion (10B). Releasable engagement means (50, 250) are provided for detachably engaging the lower jettisonable fuselage portion (10B) and the upper pilotable fuselage portion (10A). The releasable engagement means (50, 250) is actuatable in flight to enable the upper pilotable fuselage portion (10A) and the lower jettisonable fuselage portion (10B) to be disengaged from one another. The upper pilotable fuselage portion (10A) can be flown in the absence of the lower jettisonable fuselage portion (10B).
