Abstract: An elongate diffuser is disclosed comprising a diffuser body and a membrane attached to the diffuser body. The membrane is connected to the diffuser body so that introduction of gas at a working pressure into the diffuser displaces part of the membrane from contact with the diffuser body to provide an elongate sealed compartment between the membrane and a surface of the diffuser body. The compartment has a first lateral side interface region where the membrane contacts the diffuser body, a laterally intermediate region where the membrane is spaced apart from the diffuser body and a second lateral side interface region where the membrane contacts the diffuser body. The diffuser body surface which bounds the compartment comprises a recessed portion which is recessed away from the membrane between the first second lateral side interface regions.

Abstract: An elongate diffuser (10) comprises a diffuser body (30), and a membrane (20) attached so that introduction of gas at a working pressure into the diffuser displaces part of the membrane (20) from contact with the diffuser body (10) providing an elongate sealed compartment (50) between the membrane (20) and a surface (32) of the diffuser body (30). The gas can pass from the compartment (50) through the membrane (20) for aeration of fluid in which the diffuser (10) is immersed. The diffuser body surface (32) which bounds the compartment (50) is recessed away from the membrane (20) in use, to contribute to the lateral cross sectional area of the compartment (50) and facilitate distribution of gas along the diffuser by the compartment (50). An automatic purge valve for purging water from a gas feed pipe of a diffuser is also disclosed.

Abstract: A trough includes an elongate trough body and at least one elongate support element. The trough body includes at least one longitudinal side wall portion and a bottom portion which are integral with one another, or attached to one another along respective longitudinal edges. The support element extends along the outer face of the side wall portion. The support element may be restrained from moving outward, away from a longitudinal trough centerline, by connecting a restraint located inside the trough to the support element. The side wall portion is maintained upright partly by tension in the support element or in the restraint. In one embodiment, a plastics sheet material is bent into a U-shaped animal feed trough with opposite side walls supported upright by tension in longitudinal supporting wires and transverse restraint wires, the ends of which connect to the support wires through respective perforations in the side walls.

Abstract: An outrigger for supporting an elongate electrical conductor from a support. The outrigger has a first elongate limb 11 and a second elongate limb 12. An elongate electric conductor 13 is suspended from a first support device 14 located at a distal end 15 of the first limb 11. In use, the second limb 12 is attached by a first connector 16 to a length portion of an elongate element 18 so that the second limb 12 is rotatable about an axis that is parallel to a longitudinal axis of the elongate element 18. The first limb 11 is connected to the second limb 12 by a second connector 24. The first limb 11 is rotatable relative to the second limb 12 about a pivot axis of the second connector 24. A restrictor 36 limits rotation of the first limb with respect to the second limb about the pivot axis.

Abstract: A human-powered borehole drill bridges the gap between large drilling rigs and the other less-effective manual methods. Intended mainly for developing countries, the design is affordable and also extremely simple, as very little product support or spare parts will be needed. The drill uses conventional drill pipe and drill bits allowing the drill system to mimic more conventional methods of drilling and existing hardware to maintain uniformity in drilling and easier access to more drilling products.
