Abstract: A head (10) for a suction cleaner is described. The head (10) including: a lower housing portion (12); an upper housing portion (14); and a rotatably mounted brush bar (26) mounted within the housing portions (12, 14). The upper housing portion (14) is pivotable relative to the lower housing portion (12) between a closed position for use and an open position in which the brush bar (26) is exposed from above and the front.

Abstract: An apparatus to protect a wear surface of a vehicle, the apparatus having a resilient layer and a fabric layer bonded to the resilient layer, wherein the fabric layer is configured to be bonded to the wear surface of the vehicle. Other embodiments include an apparatus to protect a vehicle wear surface, the apparatus having a plurality of liner sections, wherein each liner section is configured to cover and be adhered to a portion of the vehicle wear surface, each of the plurality of liner sections including a resilient layer bonded to a fabric layer, wherein the fabric layer is configured to be adhered to the vehicle wear surface. Other embodiments include a method to protect a vehicle wear surface, the method including covering the vehicle wear surface with a plurality of liner sections wherein each liner section has a resilient layer and a fabric layer, adhering the fabric layer of each liner section to the vehicle wear surface, and joining adjacent liner sections together.

Abstract: A dust separating and collecting apparatus for a suction cleaner comprising at least one cyclonic separating device (10) having a body (12) through which a stream of air with dust therein can be caused to flow by a suction unit from an air inlet (16) to an air outlet (18) of the device, said inlet and outlet being at or adjacent one end of the body and said separating device further having a lateral outlet (20) at or adjacent the other end of the body for dust separated from the airstream in the course of its passage through the separator; and a receptacle (34) for the separated dust, the receptacle being movably disposed alongside said separating device (10) and having an inlet (42) for separated dust communicating with the dust outlet (20) of the separating device. Preferably there are two cyclonic separating devices (10, 11) and the receptacle (34) lies generally between them.

Abstract: A filter assembly for filtering pond or aquarium water includes a container (1,2) with an inlet chamber (15) having an upstream region (36) and a downstream outlet (13) leading to an outlet chamber (22). A filter (16) is positioned in the inlet chamber (15) between the upstream region (36) and the outlet (13). In use, progressive clogging of the filter causes the water pressure in the upstream region (36) to rise until it reaches a predetermined threshold when a normally-closed relief valve (28,29) opens to allow water to pass from the upstream region (36) to the outlet chamber (22) without passing through the filter (16). The valve has a coloured valve stem (28) providing a visual indication that the valve is open and that the filter is blocked and requires cleaning. In one embodiment, the outlet chamber (22) contains a source (19) of ultra-violet radiation to which the flow of water is exposed, regardless of whether the valve (28,29) is in the open or closed condition.
