Abstract: An inflatable evacuation slide is presented that includes an aerodynamic spoiler to kill the lift caused by air flowing laterally over the slide. The slide preferably comprises a fabric sliding surface stretched between two longitudinal main side members. The spoiler comprises a fabric panel, supported by a plurality of fabric gussets, that extends outward from each of the main side members. When the main side member of the slide is exposed to a lateral wind load, the spoiler creates a flow separation that kills the lift generated by the airflow. By killing the lift induced by the airflow over the top of the inflatable evacuation slide, zero or negative lift is generated by the airflow over the inflatable evacuation slide, which causes the slide to deploy downward firmly contacting the ground even in high wind conditions.

Abstract: A system for deploying an aircraft emergency evacuation slide or other inflatable device utilizes an inflation gas that is stored in a partially liquified state. The inflation gas includes a gaseous compound, preferably nitrous oxide, that is capable of undergoing an exothermic thermal decomposition, which gives off heat and produces a greater number moles of inflation gas than the number of moles of gas stored. The increase in moles of gas allows a greater inflation volume for a given weight of stored gas, while the exothermic decomposition produces additional heat that offsets, to some extent, the endothermic boiling and expansion of the liquified stored gas.

Abstract: A method of lacing together two parts of an inflatable evacuation slide uses a single piece of cord that is passed through multiple pairs of apertures formed in the two parts to be joined. Thereafter, the loops formed by passing the cord through the multiple apertures are laced together and secured with a conventional key loop. In operation, once the key loop is released, since the lacing is composed of a single length of cord, rather than multiple independent loops, the tension in all of the lacing is released simultaneously thereby allowing the lacing to unravel reliably irrespective of the load on the lacing.

Abstract: The Escape System provides fast and safe escape from architecture for larger numbers of people. The system can even evacuate an entire skyscraper in just a few minutes, while age, disabilities, injuries or even unconsciousness of evacuees do not impair the efficiency ot the evacuation (they only need an assistant). Even CPR could be administered during an evacuation. The banking and geometry of the slide surface utilizes the laws of physics to separate the faster sliders from the slower ones. The maximal number of people evacuated can exceed 200 per second, or 12,000 per minute per system. Optional Escape devices, such as Escape-Tunnels, can be used alone, or enhance the functionality of the system and offer choices of escape routes to the evacuees. Either configuration can be installed in new architecture, or retrofit existing ones.

Abstract: A fire escape device for escaping a building through a widow during a fire includes a platform having a first edge, a second edge, a third edge and a fourth edge wherein the first and second edges are opposite edges.

The elongated member has a bottom wall and a pair of side walls such that the elongated member generally has U-shape cross-section taken transversely to a longitudinal axis of the elongated member. The first end of the elongated member is attached to the second edge of the platform. The platform forms an angle with respect to the longitudinal axis. The side walls extend upwardly and the elongated member extends at a downward angle when the platform is at a generally horizontal orientation.

Abstract: The present invention is a wind chute escape system using a wind pressure to control the descending speed of a person inside a wind chute. A strong landing pressure produced by a landing blower is used to decelerate the descending body to a safe landing speed. The wind pressure inside the wind chute is produced and controlled by a wind blower and the landing blower or by one of them. There are mainly two forces acted on the descending body inside the wind chute, the downward gravity and the upward wind pressure. The balance of theses two forces determines the descending speed of the escapee. Since the wind pressure inside the wind chute is under control, the descending body can be control to a desired speed. Since the wind pressure loss is small in large wind chutes of 1 to 5 feet. in diameter, and the wind pressure transfers inside the wind chute in a speed of sound, this wind chute escape system can be used for high-rise buildings or skyscrapers of hundreds, even thousands of feet high.

Abstract: The present Patent of invention “HELICAL RAMP LIFE-PRESERVER” refers to a model of helical ramp, aimed for collective use, for immediate rescue of lives subjected to a probable fire, to be used in buildings of any height, or in places that cannot be reached by the devices currently in use, such as “Magirus” stairs, or even in those where these devices can reach, but a probable delay to help would put in risk people's life in an eventual emergency state.

Abstract: A high strength T-joint for inflatable tubular is formed by forming a butt joint between the end of a first two tubular member and the side wall of a second tubular member. The opening in the side wall of the second tubular member is sized to match the end of the transverse support member so that a sealing flange can be applied to the inner surface of the joint to provide an airtight seal. A reinforcing flange comprising a disk-shaped piece of fabric having a center opening, is then bonded over the opening in the second tubular member. The center opening in the reinforcing flange is substantially smaller than the opening in the side rail member. Therefore the reinforcing flange substantially reduces the size of the discontinuity in the side wall of side rail member, thereby substantially increasing the circumferential (“hoop”) load capacity of the side wall of the side rail member and substantially increasing the rupture pressure of the joint.
