Abstract: A water collection system includes a container prop that is configured to extend across a liquid container opening of a liquid container and retain the liquid container to the container prop and also is configured to detachably attach to an elongated member, such as a hiking pole to enable extending the hiking pole out into a body of water to submerge the liquid container opening to collect water from the body of water into the liquid container. The container prop has a prop body that has retainer hooks extending from the prop body to retain a liquid container or a container adaptor and has a pole seat with a constricted seat opening that is configured to extend over an elongated member, such as the pole shaft of a hiking pole.

Abstract: A valve (10) including a first port (12), a second port (14), a third port (16) and a flexure (30), the flexure (30) being moveable between a first position which causes the first port (12) to open, a second position which causes the second port (14) to open, and a third position which causes the first and second ports (12, 14) to close, wherein at least a part of the flexure (30) is magnetisable, to provide a first magnet (32), a second magnet (34) is associated with the first port (12) and a third magnet (36) is associated with the second port (14). A valve assembly includes a pair of valves wherein only one of the valves is operable at any given time.

Abstract: An electromagnetic flexure valve (1) including: a first pole piece (50a) and a second pole piece (50b); a flexure assembly (40) a portion of which is configured for movement between a first state adjacent the first pole piece and a second state adjacent the second pole piece; a coil (20) configured to receive electrical power from a power supply and to actuate the flexure assembly between the first and second states; and a biasing configuration configured to bias the flexure assembly into the first or the second state when the coil is not powered and irrespective of the current state of the flexure assembly such that a failsafe mode is provided.

Abstract: A valve assembly comprising a valve body, a first movable pressure responsive element, and a second pressure responsive movable element, wherein the valve assembly further comprises a resilient biasing element and a movable third pressure responsive element, the resilient biasing element extending between the third pressure responsive element and the valve body and the third pressure responsive element being adapted to act on both the first and second pressure responsive elements to transmit the biasing force of the resilient biasing element to both the first and second pressure responsive elements.

Abstract: A valve assembly comprising a chamber, the chamber having an inlet which is adapted to be connected to a source of relatively high pressure fluid, and an outlet which is adapted to be connected to a source of relatively low pressure fluid, and a switch valve which is switchable between a first configuration in which the valve closes the outlet and opens the inlet, and a second configuration in which the valve closes the inlet and opens the outlet, characterised in that a flow control device is provided between the outlet and the volume of relatively low pressure fluid, the flow control device including a restrictor portion which restricts flow of fluid through the flow control device, the extent to which fluid flow is restricted decreasing as the fluid pressure in the chamber increases.

Abstract: A valve assembly having a fluid switch and a main valve for controlling fluid pressure in a working volume in three control states wherein the main valve has three ports for fluid, flow of fluid through a first port and a second port being controlled by the fluid switch being provided with an electrical signal in a first state or a second state respectively, and flow of fluid through the third port being controlled by alternating said signal, preferably rapidly, between said first and second states.
