Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
A detonator is a device used to make an explosive or explosive device explode. [1] Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages.
A shock tube detonator is a non-electric explosive fuze or initiator in the form of small-diameter hollow plastic tubing used to transport an initiating signal to an explosive by means of a shock wave (also known as a percussive wave) traveling the length of the tube. [1] Shock tube is used to convey a detonation signal to a detonator. Shock ...
A squib generally consists of a small tube filled with an explosive substance, with a detonator running through the length of its core, similar to a stick of dynamite. Also similar to dynamite, the detonator can be a slow-burning fuse, or as is more common today, a wire connected to a remote electronic trigger. [3]
A variety of musical terms are encountered in printed scores, music reviews, and program notes. Most of the terms are Italian, in accordance with the Italian origins of many European musical conventions. Sometimes, the special musical meanings of these phrases differ from the original or current Italian meanings.
The exploding-bridgewire detonator at the far left triggers a semi-spherical detonation wave through the high-speed outer explosive. (It is semi-spherical because the exploding-bridgewire acts as a point-detonator.) As the wave is transferred to the precisely shaped inner explosive, a new spherical wave—centered on the object—is formed.
An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge.
The foil does not come in contact with the explosive, which reduces the risk of corrosion of the foil or chemical reactions between the foil and explosive producing unstable compounds, and secondarily further reduces the risk of accidental electrical ignition of the explosive. The energy to fire the detonator is quite low
