Blank cartridges

Many blank cartridges are described in Refs 40b and 52. We are giving here only two typical examples (See Figs 1-18 1-19) reproduced from Ref 52, p 2-33. Same Figs are given in Ref 40b, p 34... 

A urine is used in small amt (ca 0.23%) as a component of EC Propellant for Blank Cartridges and Fragmentation Hand Grenades. A gravimetric method of aurine detn in EC propellant is described in US Army specification No 50-13-8B, while a colorimetric method is given in US Military Standard MIL-STD-286A(1 >60)...

Cellulodine, A mixt of NC with a small amt of cellulose was proposed by Marga in 1895. This mixt when treated with a volatile solvent for NC produced a jelly which was less viscous and easier to work than one contg only NC. The product was recommended for use in blank cartridges... 

Schultze powder and E. C. powder are known as bulk sporting powders, either because they are loaded by bulk or because, for the same bulk, they have about the same power as black powder. Bulk powders burn quickly. They are used in shot guns, in hand grenades, in blank cartridges, and occasionally in the igniter charges which set fire to the dense colloided propellent powder which is used in artillery.

Primers are not used exclusively for firearm ammunition, but have other uses which include blank cartridges, flares, flare trip wires, mortars, pyrotechnic cartridges, hand grenades, rocket-propelled grenades, ejector seat mechanisms, jettison devices, and other larger ammunition components. 

Apart from firearms ammunition other propellant-activated devices have numerous uses, for example, to drive turbines, to move pistons, to eject pilots from jet planes, to shear bolts and wires, to operate vanes in rockets, to act as sources of heat in special operations, to operate pumps in missiles, to clear blocked drill bits underground, to start aircraft engines, to jettison stores from aircraft, and generally for systems that require well-controlled sources of high force applied over relatively short periods of time. Propellants are also used in some blank cartridges. 

One definition of a blank cartridge is a percussion initiated cartridge that does not have a bullet or missile that is designed to be lethal. However, blank cartridges are dangerous if misused and serious injuries and a few fatalities have resulted from their misuse at close range. (A dummy round is not a blank as it is completely inert.)... 

Blank cartridge cases have a wide range of applications ... 

Blank cartridges can produce fatal wounds when fired at, or near, contact, and they work very well in power heads. As with firearm ammunition, blanks can also damage the eardrums when discharged. 

The validity of the particle classification scheme was tested by examining items that may produce similar particles, paying particular attention to blank cartridges, the main uses of which that are likely to be encountered in casework are cartridge tools and blank firing replica/imitation firearms. 

Note Comparison of Figure 19.1 with Table 19.1 and Table 19.2 reveals that blank cartridges are similar in composition to live ammunition and may be expected to produce discharge particles with similar composition to those originating from firearm discharge. 

Unlike firearm discharge residue, each of the blank cartridges produced a limited range of discharge particle types. 

The original particle classification scheme192 has been revised based on casework experience, research work on blank cartridges, and so forth, and a detailed analysis of 14 years of casework results. The particle classification scheme used in Northern Ireland since 1984 is given in Table 19.5. The indicative particles are in tentative order of decreasing significance.

Fig. 15.6. LC/DAD chromatogram at 220 nm obtained after preconcentration of 100 mL of groundwater sample spiked at 1 /rg/L through (a) a blank cartridge prepared using a non-imprinted control polymer and (b) a cartridge prepared using a polymer imprinted with ter-butylazine. Peaks 1 = /eisopropylatrazine, 2 = feethylatrazine, 3 = simazine, 4 = atra-zine, 5 = propazine, 6 = terbutylazine and I.S. = diuron (internal standard).
