Marman Clamp
A Marman clamp is a type of heavy-duty band clamp; it allows two cylindrical objects to be clamped together end-to-end with a ring clamp. It is sometimes also known as a "Marman ring". It consists of a circular strap with an interior V-shaped groove. Tension is applied to the strap with a threaded bolt and nuts connecting to the ends of the strap. As the tension increases, the V-groove wedges over flanges on the circular parts to be assembled, providing the force that holds the ends of the two cylinders together. The Marman clamp is an alternative to a bolted flange connection which would be heavier and require more labor to connect. Another variety uses a flat strap, used where systems carry low pressure or to hold a cylindrical object in position. Hose connectors A common use for Marman clamps is as quick-disconnect connectors in flexible aircraft fuel lines. Spacecraft separation Marman clamps are used extensively in spaceflight systems and are common mechanical load- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jubilee Clip
A Jubilee Clip is a genericised brand name for a worm drive hose clamp, a type of band clamp, consisting of a circular metal band or strip combined with a worm gear fixed to one end. It is designed to hold a soft, pliable hose onto a rigid circular pipe, or sometimes a solid spigot, of smaller diameter. Other names for the worm gear hose clamp include worm drive, worm gear clips, clamps, or just hose clips. In the United Kingdom, Ireland and some of the former British colonies, the Jubilee Clip dominated the market to the extent that Jubilee Clips tend to be known almost exclusively by their brand name. History The Jubilee brand clamp brand was started by Commander Lumley Robinson of the British Royal Navy, who was granted the first patent for his device by the London Patent Office in 1921 while operating as a sole trader. It is now subject to a registered trademark in many countries around the world. The design has been copied with many variations, and there are many other ...

Hose Clamp
A hose clamp (hose clip, hose lock or Jubilee clip (UK)) is a device used to attach and seal a hose onto a fitting such as a barb or nipple. Types Many types are available, including : Screw/band (worm gear) clamps Screw clamps consist of a band, often galvanized or stainless steel, into which a screw thread pattern has been cut or pressed. One end of the band contains a captive screw. The clamp is put around the hose or tube to be connected, with the loose end being fed into a narrow space between the band and the captive screw. When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose (or when screwed the opposite direction, to loosen). Screw clamps are normally used for hoses 1/2 inch diameter and up, with other clamps used for smaller hoses. The first patent for a worm-drive hose clamp was granted to Swedish inventor in 1896 Bergström founded “Allmänna Brandredskapsaffären E. Bergström & Co. ...

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been dep ...

Marman Products
Herbert Manfred "Zeppo" Marx (February 25, 1901 – November 30, 1979) was an American comedic actor, theatrical agent, and engineer. He was the youngest and last survivor of the five Marx Brothers. He appeared in the first five Marx Brothers feature films, from 1929 to 1933, but then left the act to start his second career as an engineer and theatrical agent. Early life Zeppo was born in Manhattan, New York City, on February 25, 1901. His parents were Sam Marx (called "Frenchie" throughout his life), and his wife, Minnie Schönberg Marx. Minnie's brother was Al Shean, who later gained fame as half of the vaudeville team Gallagher and Shean. Marx's family was Jewish. His mother was from East Frisia in Germany and his father was a native of Alsace, France, and worked as a tailor. Name As with all of the Marx Brothers, different theories exist as to where Zeppo got his stage name: His older brother Groucho said in his Carnegie Hall concert in 1972 that the name was derived from ...

Pyrotechnic Initiator
In pyrotechnics, a pyrotechnic initiator (also initiator or igniter) is a device containing a pyrotechnic composition used primarily to ignite other, more difficult-to-ignite materials, such as thermites, gas generators, and solid-fuel rockets. The name is often used also for the compositions themselves. Pyrotechnic initiators are often controlled electrically (called electro-pyrotechnic initiators), e.g. using a heated bridgewire or a ''bridge resistor''. They are somewhat similar to blasting caps or other detonators, but they differ in that there is no intention to produce a shock wave. An example of such pyrotechnic initiator is an electric match. Composition The energetic material used, often called pyrogen, is usually a pyrotechnic composition made of a fuel and oxidizer, where the fuel produces a significant amount of hot particles that cause/promote the ignition of the desired material. Initiator compositions are similar to flash powders, but they differ in burning speed, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center and NASA field center in the City of La Cañada Flintridge, California, La Cañada Flintridge, California, United States. Founded in the 1930s by Caltech researchers, JPL is owned by NASA and managed by the nearby California Institute of Technology (Caltech). The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network. Among the laboratory's major active projects are the Mars 2020 mission, which includes the ''Perseverance (rover), Perseverance'' rover and the ''Mars Helicopter Ingenuity, Ingenuity'' Mars helicopter; the Mars Science Laboratory mission, including the ''Curiosity (rover), Curiosity'' rover; the InSight lander (''Interior Exploration using Seismic Investigations, ...

Explosive Bolt
A pyrotechnic fastener (also called an explosive bolt, or pyro, within context) is a fastener, usually a nut or bolt, that incorporates a pyrotechnic charge that can be initiated remotely. One or more explosive charges embedded within the bolt are typically activated by an electric current, and the charge breaks the bolt into two or more pieces. The bolt is typically scored around its circumference at the point(s) where the severance should occur. Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches. In applications that require safety, precision and reliability, such as the aerospace industry, pyrotechnic fasteners are triggered using exploding bridgewire detonators, which were themselves later succeeded by slapper detonators. Classical blasting caps are generally avoided for such usage. More recent developments have used pulsed laser diodes to detonate initiators ...
