Diagram of a bellows-operated blowpipe, circa 1827, from A Practical Treatise on the Use of the Blowpipe. If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot.
A blowgun (also called a blowpipe or blow tube) is a simple ranged weapon consisting of a long narrow tube for shooting light projectiles such as darts. It operates by having the projectile placed inside the pipe and using the force created by forced exhalation ("blow") to pneumatically propel the projectile.
Blowpipe was replaced by the Javelin surface-to-air missile, which was of a generally similar design but with an improved performance and a semi-automatic guidance system – the operator now controls the missile by keeping the target in his sight, and the aiming unit steers the missile to remain centred in the sight. A computer in the missile ...
Blowpipe may refer to: Blowpipe (missile), a man-portable surface-to-air missile; Blowgun (also called a blowpipe or blow tube) is a simple weapon in which a missile, such as a dart, is blown through a pipe; Blowpipe (tool), used to direct streams of gases into any of several working media; Blowpipe (Transformers), several Transformers characters
In the diagram, these are stands of drill pipe which are 2 or 3 joints of drill pipe connected and stood in the derrick vertically, usually to save time while tripping pipe. Drill string (#25) is an assembled collection of drill pipe, heavy weight drill pipe, drill collars and any of a whole assortment of tools, connected and run into the ...
General arrangement of the Tuyere (2), Tuyere cooler (1), Tuyere-cooler holder (3), Blowpipe (4) and Bustle Pipe (9) in a Blast Furnace. [6] A bloomery normally had one tuyere. Early blast furnaces also had one tuyere, but were fed from bellows perhaps 12 feet (3.7m) long operated by a waterwheel.
The flashback arrestor prevents shock waves from downstream coming back up the hoses and entering the cylinder, possibly rupturing it, as there are quantities of fuel/oxygen mixtures inside parts of the equipment (specifically within the mixer and blowpipe/nozzle) that may explode if the equipment is incorrectly shut down, and acetylene ...
The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types. Conversely, some locomotives have components not listed here.
