Abstract: The present invention relates to a device for metering the flow of a fluid. A fluid-metering device for a hose or pipe, comprises: a body (10) having an inlet (12) and an outlet (11); an impeller (20) drivable by a flow of fluid through the device; a barrel (40), having an inlet (42) and an outlet (43), slidably mounted in the body (10) such that the barrel (40) is slidable between an open position wherein the barrel inlet (42) and outlet (43) are aligned with the body inlet (12) and outlet (11) such that a fluid can flow through the device and drive the impeller (20), and a closed position wherein the barrel inlet (42) and outlet (43) are offset from the body inlet (12) and outlet (11) such that a fluid cannot flow through the device, the barrel (40) being biased towards the closed position; and latching means (50) arranged to hold the barrel (40) in the open position, wherein a predetermined number of rotations of the impeller (20) will release the barrel (40).

Abstract: A drinking vessel comprises a generally cylindrical container (10) for containing liquid, and a lid (20). The lid comprises a generally cylindrical inner member (21) and a generally cylindrical sealing element (30) which surrounds the inner member (21). The container 10 further comprises a rim (14) and an inner circumferential sealing surface (15). The lid (20) is fixedly insertable into the container 10 in order, when the lid (20) is inserted, to cause the sealing element (30) to lie against the sealing surface so as normally to form a seal with the sealing surface (15). The seal is deformable by suction at the rim (14) such that under the action of the suction liquid within the container (10) is caused to flow from a chamber (13) inside the container out past the rim (14).

Abstract: A ventilable portable structure arrangement is transformable between a collapsed state and an erected state. The assembly comprises a first portion (102) of foldable material arranged to define, when in the erected state, an interior chamber (106). A second portion (104) of foldable material is also provided and arranged to define, when in the erected state, a thermal chimney having an inlet (116) at one end thereof and an outlet (118) at another end thereof. The first and second portions (102, 104) are arranged so as to permit, when in the erected state, flow of air through the interior chamber (106) into the thermal chimney via the inlet (116) in response to heating of air substantially passing through the thermal chimney, the air entering the thermal chimney being expelled from the thermal chimney via the outlet (118).

Abstract: Protective eyewear, for example swimming goggles, is known to possess a nose bridge. Known adjustment mechanisms for the nose bridge either require a mechanism that cannot be adjusted in situ, i.e. when the goggles are in use, and so is inconvenient, or that does not reliably maintain the eyepieces over the eyes of a wearer, for example when the wearer dives into water. The present invention therefore provides eyewear (100) comprising a first eyepiece (102) and a second eyepiece (104). The first eyepiece (102) is coupled to the second eyepiece (104) by a cord (114). At least one of the first and second eyepieces (102, 104) is translatable, when in use, relative to the cord (114) upon overcoming a translation resisting force.

Abstract: According to the invention a drinking vessel (10) comprises a generally cylindrical container (11) adapted to contain liquid and a generally cylindrical lid (12) adapted to close the container. The lid comprises a generally cylindrical outer member (20), a generally cylindrical inner member (22) located within the outer member so as to define a generally cylindrical aperture (50) between the outer surface of the inner member and the inner surface of the outer member, and a generally cylindrical sealing element (21) located in the aperture. The sealing element normally forms a seal between the outer surface of the inner member and the inner surface of the outer member but is deformable by suction at the end of the aperture remote from the container so as to cause liquid within the container to flow, from the end of the aperture adjacent to the container, out through the aperture under the action of the suction.
