Abstract: A filter assembly comprises a fluid inlet, a fluid outlet and a filter medium for receipt of fluid from the fluid inlet and for supplying filtered fluid to the fluid outlet, the filter medium being located between the fluid inlet and the fluid outlet. The assembly further comprises pressure-limiting means, such as a pressure-relieving valve, located between the fluid inlet and the filter medium.

Abstract: A shut-off valve (10) comprises a valve housing (12, 14) having a valve inlet (28), a valve outlet (30), a fluid flow channel (32) extending between the valve inlet and the valve outlet, a valve closure member (34) displaceable into the fluid flow channel to prevent fluid flow through the flow channel and a volume within the housing for receiving a compressed absorbent body (42) which expands when in contact with liquid. The compressed absorbent body (42) is configured to displace the valve closure member (34) into the fluid flow channel (32) when expanded, and the housing (12, 14) comprises a closable aperture (52) which allows access to the volume for replacing the absorbent body.

Abstract: A filter insert (10) comprising: a body portion (12) and a closed-ended tube (14), an open end of which is sealingly affixed around the periphery of the body portion (12); an inlet aperture (16) and an outlet aperture (18) each aperture communicating via a through hole in the body portion (12) with the interior of the tube (14); a filter medium (20) located within the tube (14) and being sealingly interposed between the inlet aperture (16) and the outlet aperture (18), wherein the tube (14) is at least partially manufactured of a flexible plastics material, and wherein the body portion (12) is relatively rigid.

Abstract: In a washer dryer in which a drum supported by a spider is rotatable in a tub, the rear wall of the tub is contoured such as by providing castellation-like recesses, and water may be fed over this rear wall via a water inlet so that, in a drying mode, when the drum is rotated and moist air is drawn from the drum, the moist air is agitated by being dragged by the rotation of the drum past the tortuous profile over which water is trickled, to promote efficient condensation before the air is heated and returned to the drum in a recirculating path.
