Abstract:
The invention relates to a covering construction in a flexible device for covering heaped or stacked material, in particular for the aerobic treatment of organic-containing waste, for example residual waste or domestic refuse, in a compost heap. The covering construction has a cover which comprises a number of support elements which can be filled with at least one fluid and are connected to one another at least in part, and also at least one waterproof and gas-permeable sheet which is connected to the support elements. The device forms an erected state and a lowered state, depending on whether the support elements are filled or not. The sheet covers the material and undergoes a raising and lowering process via the filling and emptying of the support elements.

Abstract:
An airbeam, inflated to create a structural member, has three functional layers in its wall: a flexible gas barrier and a braided reinforcing layer plus the novelty of an additional braided layer. Key design factors are the bias angles of the braids in the two braided layers: that of the inner one greater than 54.7 degrees bias angle and of the outer one less than 54.7 degrees bias angle. The two layers of braid being slipped over another allows the airbeam to be formed with bends for a wide variety of shapes.
Abstract:
An airframe supported tent 10 includes at least one pair of coupled airbeams 12. The coupled air beams 12 include first 36a and second 36b redundant airbeams for providing support to the tent structure 10 when inflated. The airframe supported tent 10 also includes an interface 14, fluidly coupled to each of the first and second redundant air beams 36, for allowing all of the airbeams to be inflated and deflated through the interface. An air pump 50 is also provided which is small, compact and lays generally flat when compressed. The air pump 50 couples with the interface 14 on the tent, to inflate and deflate all of the air beams generally simultaneously.
Abstract:
A kit for building a structure which includes a plurality of panels (28, 30), each panel having at least one respective peripheral formation (34) and a plurality of fasteners (10); each fastener having at least two clip formations (12, 14), and wherein the clip formations of a fastener are respectively engageable with the peripheral formations of two of the panels which are positioned adjacent each other, to secure the panels together.
Abstract:
A shelter provides protection against airborne contaminants such as, biological, chemical or radioactive agents. The shelter includes an isolating unit having impermeable panels, frame members and at least one entrance. The shelter further includes an occupant interface to the exterior and at least one control interface. In addition, a method for protecting occupants against threats within the inner space of a chamber is provided.
Abstract:
In the present invention an inflatable tent comprising a pliable base is connected to a pliable shell. An inflatable support rib is connected to the pliable shell, and a support frame is connected to the pliable shell.
Abstract:
This invention comprises an inflatable structure that is constructed by combining polyhedron structural elements to form more complex geodesic structures. The structural elements are constructed out of straight inflatable tubes, in which the warp of the polyester reinforced fabric is aligned with the principal tube axis, giving it high resistance to bending. The complementary leg ends are connected at the vertices with connectors that comprise a slider and track formation, fixed along the axial angle at the end of each leg. Each leg end is shaped along the natural complimentary lines along the intersecting surfaces of the adjacent structural element. Once assembled, in combination with a fabric cover and groundsheet, the tent is stable and completely freestanding.
Abstract:
An inflatable temporary work shelter. In one embodiment, the shelter has an inflatable framework and a covering material. In a second embodiment the shelter could be formed of inflatable panels. The shelter includes a spine formed between two separate bearing frame members which, on inflation, contact each other. When inflated, for example, from a position beneath a structure such as an aeroplane wing suspending an engine pod by a pylon, the shelter will initially impinge against the engine pod and because the shelter is not fully inflated the spine will open and allow the shelter to continue to rise until fully inflated when the spine will be light on the pylon and the shelter will contain the engine.
Abstract:
A pneumatic wall structure and a method of making and erecting same. The pneumatic wall structure includes an inner flexible tent sheet, a central flexible tent sheet and an outer flexible tent sheet. The inner, the central and the outer flexible tent sheets are arranged to form a two-layer wall structure comprising (i) an inner layer formed by the inner tent sheet and the central tent sheet and, (ii) an outer layer formed by the central tent sheet and the outer tent sheet. The inner layer is inflatable and provides a main support structure for the wall structure, and the outer layer forms a convection space into which an ambient air is capable of flowing. The inflatable support tubes are arranged between the central tent sheet and the outer tent sheet to provide redundancy to the main support structure and to provide a spacer between the central tent sheet and the outer tent sheet.
