Abstract: A centrifugal separator apparatus for separating components of a fluid stream; the apparatus comprising a support structure and a centrifugal separator unit rotatably mounted on the support structure so as to be rotatable about a rotational axis extending through the centrifugal separator unit; a drive element for driving rotation of the centrifugal separator unit; wherein the centrifugal separator unit comprises a centrifugal separation chamber having an inlet which is connected or connectable to a source of fluid requiring separation, a first outlet for collecting a higher density component of the fluid stream, and a second outlet for collecting a lower density component of the fluid stream; the first outlet being connected or connectable to a first collector for collecting the higher density component and the second outlet being connected or connectable to a second collector for collecting the lower density component; the centrifugal separation chamber comprising a curved or inclined guide surface for g

Abstract: The invention provides an apparatus for providing potable water, which apparatus comprises a plurality of components linked in series to provide a flow path through the apparatus, wherein the plurality of components comprises: (i) an inlet (4) for a stream of contaminated water requiring purification; (ii) a centrifugal separator (20) for separating the contaminated water stream into a partially purified water stream and a contaminant stream; (iii) a pre-filter pump (26); (iv) a pre-filter pressure sensor (30); (v) a first filter assembly (32) comprising one or more filter modules for removing particles of a predetermined size and/or removing organic contaminants from the partially purified water stream; (vi) a post-filter pressure sensor (38); (vii) a post-filter pump (40); (viii) a second filter assembly comprising one or more reverse osmosis filters (48); (ix) a UV steriliser unit (52); and (x) an outlet (6) for purified potable water; and wherein the apparatus further comprises an electronic controller (

Abstract: The present invention relates to an infant seat and crib arrangement (10). The infant seat and crib arrangement (10) comprises a seat (14) configured to support an infant in a sitting position, a crib configured to enclose an infant and a frame (12). The frame (12) is configured for change between a first disposition in which the seat (14) engages removably with the frame to thereby bring the seat into use and a second disposition in which the crib removably engages with the frame to thereby bring the crib into use.
