Abstract: Water filters which comprise a multitude of discrete filter media elements in a chamber require periodic cleaning. However, the elements tend to become adhered to one another and to the interior surface of the chamber. The invention provides a water filter for use with ponds, comprising a filter chamber for containing filter media, and a first movable cutting member provided substantially immediately adjacent the interior wall of the chamber for movement across the surface of the interior surface of the wall to break the adherence of filter media to the interior wall.

Abstract: Dosing chambers, for use with pressurized water filters of the type used with ponds, require isolation before accessing to prevent water egress. The invention comprises a chamber in which dosing substances may be placed, a water inlet and a water outlet, a lid for sealingly closing the chamber, a valve for closing the water inlet and an interlock means for operating the valve to close the water inlet as the lid is removed, so that when dosing substances are placed into the chamber pressurized water is prevented from issuing through the inlet.

Abstract: Dosing chambers, for use with pressurised water filters of the type used with ponds, require isolation before accessing to prevent water egress. The invention comprises a chamber in which dosing substances may be placed, a water inlet and a water outlet, a lid for sealingly closing the chamber, a valve for closing the water inlet and an interlock means for operating the valve to close the water inlet as the lid is removed, so that when dosing substances are placed into the chamber pressurised water is prevented from issuing through the inlet.

Abstract: Water filters require filter media which may be a substantially single structure such as open-cell foam, or comprised of a plurality of relatively small elements. The present invention provides composite mechanical water filter media for use in mechanical water filters comprising a plurality of first elements having a first shape and a plurality of second elements having a second shape, the first and second shapes being substantially different from one another, the elements being arranged to interlock with one another.

Abstract: Systems and methods for recovery based social networking are presented. Users of the social network platform can select different groups of individuals that have access to different portions of the content that the user generates through the social networking platform. Private health information can be maintained separately from information generated by the user through the social networking platform. Healthcare professionals can access both private and user generated information in order to support the user's recovery.

Abstract: Systems and methods for recovery based social networking are presented. Users of the social network platform are presented with selectable status indicators relating to their recovery. The selected indicators are shared with user selected supporters and health care professionals so that the supporters and healthcare professionals can support recovery. Automated analysis of the users' interactions with the social networking is also performed to predict when users will need additional support so that the supporters and healthcare professionals can be notified.

Abstract: Systems and methods for recovery based social networking are presented. An analysis module analyzes past and current activity of users on the social networking platform. The analysis module predicts, based on user activity, when particular users will need support from user identified supporters and healthcare professionals. The analysis module sends alert messages to the pre-determined supporters and healthcare professionals soliciting support responsive to the predictions.

Abstract: Apparatus for facilitating the removal of material deposited at the bottom (6) of a volume of liquid (7) the apparatus including a suction pump assembly (2) associated with a suction head/nozzle (9) mounted to a user handling element (4) and means (24) drivable by the motor for displacing sucked-in water and (8) to a delivery location (11), in such manner that when used in use the pump assembly (2) can be submerged, and wherein the suction pump assembly (2) includes means (40) for enabling controlled air escape from the vicinity of the means (24) for displacing air from of the pump assembly the arrangement being such as to prevent air blockage of and material flow through the pump following raising of the latter of water.
