Abstract: An air sanitiser unit includes a housing including a base with one or more mounting formations for mounting the base on a substantially vertical wall or support structure and a lid having an air inlet vent and an air outlet vent. The lid is releasably attached to the base to provide an enclosure. At least one ultraviolet lamp is enclosed within the housing to prevent exposure of the ultraviolet lamp from outside of the housing. One or more diffuser elements are enclosed in the housing adjacent to the ultraviolet lamp including one or more photocatalysts. A control device is enclosed in the housing with an alarm device. The control device is electrically connected to the ultraviolet lamp and the alarm device and is configured to control the alarm device according to the status of the ultraviolet lamp.

Abstract: A wash basin (2) includes a bowl unit (4) and a skirt (6) that supports the bowl unit. The bowl unit (2) is made mainly or entirely of metal and the skirt (6) is made mainly or entirely of a moulded thermoplastic material. The skirt (6) includes a peripheral rim (28) that is located beneath an edge portion (29) of the bowl unit to support that bowl unit, and the bowl unit (4) and the skirt (6) are bonded together.

Abstract: A waste disposal apparatus for disposing of waste materials using aerobic decomposition includes a decomposition chamber, a waste inlet configured to admit waste materials into the decomposition chamber, a water feed system configured for supplying feed water to the decomposition chamber and a drain system configured for draining drain liquid from the decomposition chamber. The apparatus also includes a sensing system configured to sense the volume VF of feed water supplied to the decomposition chamber and the volume VD of drain liquid drained from the decomposition chamber, and a computing device that is configured to determine the quantity of waste material processed by the waste disposal apparatus from the sensed volumes VF and VD.

Abstract: A grease trap (1) device for trapping waste material including water and fats, oils and/or greases (FOGs), and for removing at least some of the FOGs from the water. The device includes a first receptacle (3) having a storage volume (31) for storing waste material in a manner that enables FOGs to float on the surface of the water; an inlet (9) for receiving waste material into the first receptacle; a drain (49) having an inlet (47) positioned to capture FOGs floating at and/or near the surface of the water, and an outlet (51) positioned for transferring waste material out of the storage volume; a valve (53) for controlling the flow of waste material through the drain; an outlet (15) enabling cleaned water to exit the first receptacle; and at least one heat exchanger unit (57,59) arranged to remove heat from the waste material stored in the first receptacle.

Abstract: A tap including a body; a valve including a first part which is fixed to the body and a second part arranged for limited rotation with respect to the first part; and a handle fixed to the second part, said handle including a housing mounted over at least a part of the valve, said housing including first and second blocking members; and the body, and/or a part of the tap fixed to the body, includes third and fourth blocking members; the first blocking member arranged to engage with the third blocking member to limit rotation of the handle in a first direction; the first blocking member arranged to engage the fourth blocking member to limit rotation of the handle in the second direction; the second blocking member arranged to engage with one of the third and fourth blocking members to limit rotation of the handle in one of the first and second directions; the first, second, third and fourth blocking members located within the housing.

Abstract: A drain connector includes a fixed unit (2) having a first drain conduit for permanent attachment to a drain pipe and a detachable unit (6) having a second drain conduit for attachment to a removable appliance (8). The fixed unit (2) includes a first drain connector element (36) and the detachable unit includes a second drain connector element (18) for detachable connection with the first drain connector element. The fixed unit (2) further includes a closure member (44) that is adjustable between an opened condition and a closed condition in which it substantially closes the first drain conduit, to prevent the passage of rodents through the conduit.
