Airlock

An airlock is a device which permits the passage of people and objects between a pressure vessel and its surroundings while minimizing the change of pressure in the vessel and loss of air from it. The lock consists of a small chamber with two airtight doors in series which do not open simultaneously.

An airlock may be used for passage between environments of different gases rather than different pressures, to minimize or prevent the gases from mixing.

An airlock may also be used underwater to allow passage between an air environment in a pressure vessel and the water environment outside, in which case the airlock can contain air or water. This is called a floodable airlock or an underwater airlock, and is used to prevent water from entering a submersible vessel or an underwater habitat.

Use

Before opening either door, the air pressure of the airlock—the space between the doors—is equalized with that of the environment beyond the next door to open. This is analogous to a waterway lock: a section of waterway with two watertight gates, in which the water level is varied to match the water level on either side.

Airlock (parachute)

A parachute airlock (simply airlock in context) is a safety mechanism built into some parachute models which resist it losing its shape while open. It uses a ram air structure to stiffen each section of the outer edge.

The design was pioneered by parachute inventor Brian Germain following a near-fatal ram-air wing collapse in 1994. Germain made a full recovery to personally test many of the airlock prototype parachutes, often in extreme conditions. Specific parachute designs utilizing the Airlock technology include the following: Jedei, Sweptwing, Genesis, Warlock, (AirTimeDesigns.com) Vengeance, (PerformanceDesigns.com) Samurai, Lotus, Sensei R1 (BigAirSportz.com).

While the airlock approach to canopy design has generated an enthusiastic user base, the design also has its problems. For example, a ram-air parachute designed with airlocks will not deflate quickly upon landing on a windy day. This may result in dragging a parachutist across the ground. Parachute packers have also noted that these canopies take longer to pack due to the extra time it takes to squeeze the air out. However, proponents prefer the safety advantages of a stable canopy in flight over inconveniences on the ground.

Airlock (band)

Airlock is a Belgium based trip hop musical group formed November 1997 in Brussels notable for their ambient music on several popular TV series: CSI: Crime Scene Investigation and CSI: Miami. The band members were Renaud Charlier, Ernst W. Meinrath and Pierre Mussche.

Danger Man

Danger Man (titled Secret Agent in the United States, and Destination Danger and John Drake in other non-UK markets) is a British television series which was broadcast between 1960 and 1962, and again between 1964 and 1968. The series featured Patrick McGoohan as secret agent John Drake. Ralph Smart created the programme and wrote many of the scripts. Danger Man was financed by Lew Grade's ITC Entertainment.

Series outline

From the 1st series voice-over:

The line "NATO also has its own" is not always present.

Programme overview

The first series of episodes ran to 24–25 minutes each and portrayed John Drake as working for a Washington, D.C.-based intelligence organization, apparently on behalf of the North Atlantic Treaty Organization, whose assignments frequently took him to Africa, Latin America, and the Far East. In episode 9, "The Sanctuary", Drake declares he is an Irish-American.

He sometimes seemed at odds with his superiors about the ethics of the missions. Many of Drake's cases involved aiding democracy in foreign countries and he was also called upon to solve murders and crimes affecting the interests of either the U.S. or NATO or both.

Dangerman (band)

Dangerman is an alternative rock duo out of New York. Lead singer Chris Scianni fronts the band and plays guitar and bass, while Dave Borla plays percussion, keyboards and does most of the programming. Their critically acclaimed, self-titled debut studio album Dangerman was produced by the highly respected Brendan O'Brien and released in 1999 on Sony/Epic/550 Records. Included on this album is their most-recognizable track, "Let's Make a Deal (Vamos a Negociar)" (which held a high chart position on the Billboard charts for months in 1999), and a tribute song that samples audio from Mississippi Fred McDowell's "I Do Not Play No Rock and Roll", "Listen to the Music".

Also written by Dangerman, is the opening and closing song to the movie Dude, Where's My Car?
