A circular parachute includes a circularly shaped canopy having a skirt band and a plurality of cascaded, Y-shaped main suspension lines connected to the skirt band that converge downwardly to a suspension line junction. Each main suspension line includes a lower segment that branches into at least two upper segments. One embodiment includes a canopy with a vent band and Y-shaped vent suspension lines that converge downwardly to a vent centerline. A generally planar reefing device for slowing the opening of the canopy defines a plurality of openings through which the main suspension lines extend. In one reefing device embodiment, a strip of material (e.g., a nylon strap) is folded into multiple strip segments arranged in a five-point star configuration. Eyelets in the form of brass grommets extending through the strip segment junctions form suspension-line-receiving openings.

An easy open packaging pouch, including a packaging film, with a bonded peripheral edge section that has been formed by superimposing the packaging film such that two bonding layers are facing one another such that the peripheral edge of the packaging film is bonded. The package is designed to tear open from a notch formed in the peripheral edge, and a content is placed such that a tear starting from the starting point will intersect the content during opening. Opening includes tearing along a tear line that advances diagonally, with respect to the content, from the notch. Once the tear reaches the content, the tear diverges in two directions; one continuing in a substantially unchanged direction, and the other inflecting along the content. Opening will expose an end portion of the content.

Reduced door opening force and enhanced security flight deck door mechanism
InactiveUS20060076457A1Reduce door opening forcePowerfulNon-mechanical controlsFuselagesEngineeringMechanical engineering
An aircraft door mechanism includes a solenoid connected to a support assembly. The solenoid displaces the latch pin between a solenoid energized and a solenoid de-energized position. A catch assembly rotatably connected to the support assembly is positioned to engage a 3-½ degree or less taper portion of the latch pin in the solenoid energized position. When the latch pin moves to the solenoid de-energized position, a latch bolt supported by the door rotates the catch assembly. The latch bolt includes a distal bulbous end which multiplies the force applied to the door to rotate the catch assembly. If the latch pin is extended, a substantially greater force is required to force the latch pin to the solenoid de-energized position owing to the reduced taper of the latch pin. Authorized door entry is therefore easier and unauthorized door entry is made more difficult.

A liquid level control system employs a flap gate for discharging liquid, but with a midstream headloss inducing device between the basin or tank and the flap gate. The flap gate opens when liquid level in the basin rises, and the opening of the gate is controlled by a counterweight positioned so as to decrease closing force as the gate opens farther, thus managing the outflow of liquid to efficiently return the basin to a design level. If flow from the basin is generally constant, the system will reach a point of equilibrium of gate opening and closing forces while liquid flows out from the basin.
