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: A floating solar system comprising a grid comprising a plurality of rod-cables, at least some of the rod-cables comprising fiber reinforced polymer, the grid providing a support structure for the floating solar system. The floating solar system further including a plurality of solar floats to provide buoyancy, each solar float coupled to the grid, the plurality of solar floats not providing structural support. The floating solar system designed to support a plurality of solar panels, each solar panel coupled to a corresponding solar float, the solar panel providing shade for the corresponding solar float.

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: A floating solar system be used on water, utilizes an aluminum support structure, aluminum, HDPE floatation elements which are designed to have minimal solar exposure. The aluminum support structure is designed to absorb all structural torque and other forces.

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 freestanding trough has an elongate trough body 12 and transverse restraints 14. The trough body has a bottom portion 16 integrally formed with two side wall portions 18 from a resilient semi-rigid sheet. The restraints 14 extends transversely across the inside of the trough, intermediate the ends of the trough body 23, lower than upper edges of the side wall portions but higher than the bottom portion. The side wall portions 18 are restrained from moving outward, away from a longitudinal centerline of the trough, at least in part by a tension in the restraint 14 and the side wall portions are maintained upright in part by the tension in the restraint, and in part by the resilient semi-rigidity of the sheet.

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.

Abstract: A four-wheel shopping cart includes a substantially rectangular base surrounded by vertical side, front and rear walls to form an open-topped, cargo basket. The front wall opens fully to provide access to the cargo area, while the rear wall is shorter than the others to allow easy access from behind while shopping. A transverse axle mounted below the rear wall supports hinged legs that fold upwards alongside the side walls so the cart can be placed conveniently into a vehicle for transportation. The legs unfold and lock to support the cart on castors for shopping, and may include height adjustment means for lowering the basket to a comfortable level for usage and for raising it to place it into the shopper's vehicle. A pair of small, adjustable wheels mounted on opposite front corners of the base pivot partially to facilitate maneuvering the cart within the vehicle.
