Heat of Deflagration. If an explosive, serving as a propellant (such as BkPdr or a smokeless propellant) is initiated by an electric blasting cap, in a calorimetric bomb (similar to that used for determination of heat of combstn) under confinement, but without addition of oxygen, the substance usually behaves as if it were fired in a gun barrel. This is known as "deflagration ... [Pg.374]

Booster-Gap Explosive Sensitivity Test of Cole Edwards, described in detail in USP 2832213(1958) (Ref 17). It was claimed to be more reliable and less ex. pensive than the card test (See after "card-gap test") and the three-legged table test, described here after "shock-pass-heat-filter test . The "booster-gap test serves for evaluating shock sensitivity of liquid explosives. It includes a set of snug-fitting telescopic cardboard tubes (ca 1 inch diam) and a cylindrical wooden block for holding the electric blasting cap, Tetryl booster pellet, circular spacer cards, and the cup with liquid explosive (to test) fit compactly in the cardboard tubes when... [Pg.398]

The LEDC produces very little noise on detonation and for this reason can be used in highly populated areas. It is usually recommended for operations where bottom-hole initiation is desired and electric blasting caps cannot be used for fear of prematute detona-... [Pg.734]

In Fig 5, Method A is for firing with instantaneous electric blasting caps and Method B is for instantaneous firing and for all rotation firing with delay electric blasting caps... [Pg.736]

Electric blasting caps (or electric blasting initiators) are described in Ref 44, pp B186-R to B186-L. Such caps are called "electric detonators" in Gt Britain. The type known as the "neoprene plug assembly" is described in Ref 36, pp 56-8 and Ref 38, pp 53-6 and is shown here in Fig 7. It consists... [Pg.738]

Ad 168) G.B. Young S.J. Lubinski, USP 3317360(1967) CA 67, 5265(1967) (Ignition charges for electric blasting caps, claimed to be resistant to electrostatic discharges, can be prep from amorphous B and of Pb oxides in the following mixt ranges ... [Pg.1053]

Most of the devices described above are no longer used and are only of historical interest Today, in gassy mines in the US, the explosive cartridges are detonated directly with electric blasting caps (Refs 4 5), without the use of safety fuse... [Pg.272]

C. P. Spaeth, 29, 1252 (1935) Ignition charges for electric blasting caps containing Tetramethylene diperoxide either alone or with various admixtures USP 1984846 (1934)... [Pg.281]

Ignition charge suitable for electric blasting caps and containing bis-Triethyl Lead Styphnate, C6H(N02)3 [OPb(C2H5)3] USP 2105635 (1938)... [Pg.281]

Ignition composition for use in electric blasting caps, consists of or includes a double salt of Pb(N03)2 with a Pb salt of dinitro-phenol BritP 519749 (1940)... [Pg.282]

R. W. VanDolah et al, US Bur Mines RI No 7195 (1968) CA 70, 13126 (1969). Development of Slurry Explosives for Use in Potentially Flammable Gas Atmospheres, In this rept expts with 23AN-based slurry expls showed that it is possible to have them cap-sensitive and relatively nonincendive. All slurries that used flaked Al were sensitive to No 6 EBC (electric blasting cap) except one contg AN 47.2, NaCl 10, water 30, Al (particle size... [Pg.287]

Initiation by Radio Frequency (RF) Radiation. RF radiation, ie, radio wave radar transmitters can, under certain circumstances, initiate electroexplosive devices. This topic will be discussed under Radio Frequency Radiation, Effects on Explosives. Also see articles on Electromagnetic Compatibility Electromagnetic Field Hazard, Simulated in Vol 5, pp E70-71 and Electric Blasting Caps and RF Energy in Vol 5, p E25-L... [Pg.372]

Electric Bomb Gaine, Instantaneous, length 5-3/8 depth 1-3/8 inches. Expl Train The Electric Blasting Cap fitted into hollowed-out cavity in the PA Booster. Leads from the cap ran up to a female plug which was attached by a special adapter to the standard Gaine body (p 199, Fig 148)... [Pg.477]
