Bickford fuse

One of the simplest primers is a combination of nonelectric cap (Brit "plain detonator1) with safety fuse (Bickford fuse) and a cartridge of Dynamite, as shown in Fig 1. This combination is called in US... [Pg.734]

Uses For safety fuses (Miner s fuse, Bickford fuse). For time-train rings and combination fuzes. (In mechanical devices the spelling is z.)... [Pg.72]

In Japan industrial fuse(Bickford) has recently been used in place of the hand made fuse the manufacture of the latter is quite labour intensive. In order to catch fire from some other heat source or to transfer the fire to other pieces the two ends of a cut fuse are pasted with a slurry of a prime composition. Sometimes a match composition which contains chlorate is pasted on one end so that it is ignited when it is rubbed with a red phosphorus striker. In general the slurry is a mixture of black powder and 10% nitrocellulose solution in acetone. In place of the nitrocellulose, celluloid solution can also be used. The ratio of the black... [Pg.199]

This black thread is manufactured by pasting a composition in the form of a slurry on to cotton strands. It burns slowly in the open air, but quite, quickly in a long tube with a small diameter. Unpiped quick match is often used for fire transfer in place of industrial fuse(Bickford fuse) and the paper covered fuse is used for frame-work. Various other materials are used in place of the cotton strands for cheapness. Black powder is popularly used, but chlorate composition is also used in Japan to obtain quicker fire transfer, but this is not to be recommended. [Pg.198]

A bundle of such tubes is then inverted such that an explosive charge consisting of fine grain gunpowder and mealed gunpowder can be loaded in. After this a length of Bickford-type safety fuse is glued into the top of each loaded tube. Finally a mealed powder primer and blue touch-paper are applied to the fuse end. [Pg.98]

This type of fuse was invented and patented in the U.K. in 1836 by William Bickford and subsequently became known as Bickford Euse . [Pg.185]

Explosives of this kind are known as deflagrating or low explosives. BkPdr and smoke- less propellants are examples. The simplest device for ignition is Bickford or miner s safety fuse, described in Ref 44, p B112-L. [Pg.733]

The flame produced on striking matches is used to ignite intermediate or "transfer" items of which Safety Fuses, also called Bickford Fuses (See Vol 1 of Encycl, p B112-L) are most frequently used. Blasters Hdb (Ref 50, p 97) describes fuses with BT (burning time)... [Pg.761]

These igniters, known also as lighters, are used for igniting safety fuses". Some are known in the US as "Bickford Fuses "(See Vol 3 of Encycl, p B112-L) and serve to initiate certain demolition explosives (See Vol 3 of Encycl, p D56-R)... [Pg.768]

Detonating Cord core of pentaerythritol tetra-nitrate (PETN) contained within a waterproof covering of textile or plastic available in several grades, each on spools of 500 or 1,000 feet. Manufactured by the Ensign-Bickford Company, Coast Fuse, Inc and Austin Powder Company SAFETY FUSE... [Pg.69]

Safety Fuse invented by W. Bickford (See Vol 2 of Encycl, p B112-L) and in 1840 the Bickford fuse was adopted by the English military authorities. In 1836 a factory was started in US, in 1839 in France, and in 1844 in Germany. Before 1840 guttapercha-covered fuse had been adopted for blasting under water. Various modifications have since been invented, including fuse cased in metal Colliery Fuse (patented in 1886 by Sir G. Smith), which... [Pg.134]

Low Explosives (such as Black Powder, described in Ref 1, pp B165-R to B177-R) are initiated by Fuses, Squibs and some Blasting Caps. High Explosives are initiated by Electric Blasting Caps, Detonating Cords (such as Primacord Bickford) and by Detonators... [Pg.417]

They are sometimes crimped to an end of Bickford fuse for the purpose of lighting it (Ref 1, p 453). Such a device known as Time Blasting Fuse Igniter Ml is described in Ref 2, p D768-R with Fig 19 ana on p D762-L... [Pg.585]

Fuses, Detonating. Detonating fuse, Type B material (Fig 1), is usually referred to by the trade name, Primacord (registered trade name of Ensign Bickford Co) (See Vol 2 of Encycl, p B112-R and Vol 3, p C529-R). It is widely... [Pg.634]
