Abstract: A method and system for the inflation of a sealed air product with accommodations for both a high capacity, low pressure blower and a low capacity, high pressure pump. The blower is attached to a fill tube and inflates the product until it approaches a point at which the pump does not have sufficient pressure to continue. The fill tube is coiled to prevent the air inside the sealed-air product from escaping and placed into a compartment behind a closable opening which is then closed. The air pump is then attached to an inflation port located on the sealed-air product which, when activated, inflates the sealed-air product to the desired air pressure. A pressure relief valves ensures the product is not over-inflated. After use, air may be allowed to escape through the fill tube, thereby allowing rapid deflation of the product.

Abstract: An inflatable barrier system for a doorway or other opening comprising a front side envelope of rectangular front elevation and dog bone shaped horizontal plane cross section, inflatable with gas and fillable with a hardening foam, combined with an inflatable back side array of tubular air beams configured with self sealant, both connected to a source of gas for inflating the fabric envelope and the back side array of tubular air beams. The front side envelope is configured for frontal resistance to predetermined levels of push, cut, puncture, flame, chemical, and ballistic attack. The system is used as a method for closing a doorway to such attacks by erecting and inflating the system within the opening such that the edges on either side of the opening are gripped between the lobes of the respective ends of the dog bone profile of the front side envelope.

Abstract: An inflatable and rigidizable structure for use as a habitat or a load bearing structure is disclosed. The structure consists of an outer wall and an inner wall defining a containment member and a bladder. The bladder is pressurized to erect the structure from an initially collapsed state. The containment member is subsequently injected with rigidizable fluid through an arrangement of injection ports. Exhaust gases from the curing rigidizable fluid are vented through an arrangement of exhaust ports. The rate of erection can be controlled by frictional engagement with a container or by using a tether. A method for fabricating a tubular structure is disclosed.

Abstract: A prefabricated shell for forming a shelter (14) has a groundsheet (30) and a cover (32) having a gas impermeable inner layer (24) and at least one outer layer. The outer layers are each formed by a layer of cloth that has been impregnated with a water-settable material, e.g. cement. The shell is steeped in water to wet the cement and then the cover is pneumatically inflated to form a space between the cover and the groundsheet. The shelter is then left until the cement has set and is able to support the cover. The shelter can easily be constructed to provide a durable shelter, especially in emergency areas.

Roof members (8, 9, 10, 11 and 12) (FIGS. 2 and 3) may be provided also. The roof is formed by inflating roof supports (8, 9) and (10), forming a further roof member (11) from settable cement material above the roof supports (8, 9) and (10), deflating the roof supports (8, 9) and (10) when the further roof member (11) has set to leave the further roof member (11) in place and forming a structural roof member (12) above the roof member (11). The containers and/or inflatable supports may be formed from dropstitch material which provides internal reinforcing. The invention allows free-standing rigid structures to be produced without the need for conventional formwork.

Abstract: A stay-in-place composite form provides a strong and durable concrete structure. The form includes a composite shell having an inner wall surface defining an enclosure into which concrete may be poured and allowed to harden. The composite shell may be made of one or several layers of fabric having a resin matrix impregnated therein. The concrete hardens to form a concrete core within the enclosure and a liner is affixed to the inner wall surface of the composite shell to protect the composite shell from alkalinity in the concrete core. The liner includes at least one sheet of a water-impermeable material to protect the concrete core from water and other corrosive elements. The fabric layers are selected such that the fibers elongate as the concrete is poured into the enclosure due to a weight of the concrete and partially shrink back to compensate for shrinkage of the concrete as the concrete dries to form the concrete core.
