An exemplary controlled environment greenhouse may include an inner membrane defining an interior space and having at least one opening. The greenhouse may also include an outer membrane arranged outside of the inner membrane to define an air gap therebetween. The greenhouse may further include at least one fan configured to draw air from within the interior space through the at least one opening into the air gap, and recirculate the drawn air back into the interior space. The greenhouse may further include at least one heat exchanger configured to enable heat transfer between the drawn air and a heat transfer medium. The greenhouse may have a dome-shaped or arcuate cross-section.

The invention comprises a structure having at least two separate air chambers (7) enclosed by flexible, flat material (8) and having flexible bars (9) in the interior thereof for stabilizing an external shape of the air chambers (7). The structure is characterized in that the air chambers (7) form a wall structure (4) in the inflated state. By means of such a wall structure (4)—preferably in conjunction with a corresponding ceiling structure (16)—lightweight berths (1), particularly for aircraft crew, flight passengers, or transported injured persons, can be set up quickly and simply.

A foil cushion is described, in particular, a building envelope element with at least one foil cushion that has two outer foil layers that form, between themselves, a cavity that is advantageously closed in an essentially fluid-tight way and that contains a fluid medium, in particular, air. The special feature of the invention consists in that in the cavity there is a carrier on which a group of light-emitting diodes displaying advantageously alphanumeric symbols and/or images is attached on this carrier. Advantageously, the carrier can be arranged as an additional foil layer.
摘要:
A method of forming a building structure in a desired contoured configuration. An inner supporting fabric is inflated into at least one form. An outer finishing fabric is draped over the inflated form. A coating is applied to the outer finishing fabric and a hardening shell is formed. The inner supporting fabric may be removed. Alternately, inflatable bags, posts, cables and other devices are disposed under the outer finishing fabric to produce the desired contoured configuration. These devices are removed after the coating has cured.

A lightweight, portable, inflatable cover to protect a vehicle from the elements that can dent and damage a vehicle surface, a tent for summer camping or winter ice fishing a cover or cushion to protect items in transit. Having a multitude of air chambers (26) vertical walls adhered to a top layer and a bottom layer with openings (28) in inner vertical walls allowing air to pass through openings filling air chambers as cover is inflated. An air valve stem (46) an air release screw in plug (32) to inflate and deflate cover. Elastic opening for antenna (40), grasp handles (42), reflector strips for safety with a identification name or number (22). Doors or flaps (11) with large zippers (20), and clear inserts (48). A cord (18) and locking pulley (16) to secure cover to vehicle and grommets (36). Air vents covered with breathable material (25) prevents air lifting, and circulation of air keeps interior of vehicle cooler in the summer and air vents are insulated for winter. The cover, tent, and cushion are easy and quick to set up and take down, and repairing a tear or hole is done with a peal and stick patch and a can of spray sealer.

A battery heating device includes a temperature sensor and at least one heating element in a liquid and acid-proof arrangement inside the battery. The heating element is a power transistor secured to a cooling plate which is powered by the battery, the emitter of the power transistor being powered by a temperature control circuit when the battery temperature falls below a predetermined reference temperature and the battery voltage is higher than a lower threshold and lower than a higher threshold. A trigger circuit responds to a rise in battery voltage after the current in a load having a high current consumption is switched off. The trigger circuit actuates a timer circuit which conductively controls the power transistor for a set time if the battery voltage is under or at the lower threshold.

An inflatable, self-supporting cover suitable for placement over a body and comprising a top sheet, a bottom sheet and ribs extending between such sheets to form a plurality of compartments extending transverse to the length of the cover. The ribs are formed in the shape of a flattened oval and then fastened between such sheets. A duct extending longitudinally of the length of the cover connects with the compartments and with a source of pressurized air which inflates the compartments, causing them to assume an arch-like shape extending transverse to the length of the cover and spanning said body. An alternative embodiment includes a second cover section fastened to the cover bottom sheet and having a plurality of compartments, each with at least one port therein. The second cover section compartments connect with the duct whereby pressurized air passes to the second cover section compartments and from each port therein to circulate air about the body beneath the cover.

A bed/shelter unit comprising a lightweight air mattress and a lightweight tent on the mattress adapted to be erected as a shelter over the mattress and to be collapsed on the mattress, the mattress, when deflated, and the tent, when collapsed on the mattress, being adapted to be compactly packed as by rolling them up into a lightweight bundle. The tent comprises a panel of lightweight flexible tent material adapted to arch over the inflated mattress from one side thereof to the other, the panel having inflatable arches at its ends adapted when inflated to extend over the mattress from one side to the other. End closures at the ends of the tent hold the arches in an erected position with the panel drawn between the arches and thereby arched over the mattress.

A lightweight construction element is provided with a fabric backing from untrimmed velvet fabric, coated to render it airtight and pressure resistant, with the internal space thereof allowing pressurization. With the pressurizing medium filled in, the yarn linking the two outer fabric webs will maintain a predetermined distance between the fabric webs and ensure high stability of the element.
摘要:
An air structure comprises a double-skin wall construction having an outer skin that is substantially transparent to short wave solar radiation but relatively opaque to long wave heat radiation and an inner skin. Radiation converter elements, preferably in the form of black plastic diaphragms linking the inner and outer skins and effective to absorb solar radiation and to convert the same to heat energy are disposed in the inter-skin space. The structure is self-erecting on exposure to solar radiation, and may advantageously be combined with a heat store that emits heat and maintains the structure erected under conditions of reduced solar radiation availability. The structure may be free floating or may be anchored to the ground to form, for instance, a greenhouse or other enclosure.
