Barrel, sulphur

Ordnance propellants are required to give the minimum of muzzle flash, smoke and barrel erosion. All these objectives are assisted by adding to the propellant a proportion of nitroguanidine (picrite), made by treating guanidine nitrate with sulphuric acid and brought to very fine particle size by recrystallisation and disintegration. [Pg.187]

Table I Indicates a comparison of synthetic crude yields and product sulphur using various processing schemes. Should synthetic crude production rise to 500,000 barrels/day from the Athabasca region in the Nineties, by-product sulphur could exceed...

The twelve new and twelve used barrels used in this experiment were made of American white oak (Quercus alba, fine grain) or French oak (Quercus petraea from the Allier forest in France), and were obtained from the same cooperage firm in Spain with the same specifications (medium toast level). The used barrels had been used three times for the aging of Monastrell wine and they were sanitatied before use by burning sulphur inside. The following barrels were used in the experiment 220 liter French oak barrel (3 new barrels and 3 used barrels) 220 liter American oak barrels (3 new barrels and 3 used barrels) 500 liter American oak barrels (3 new barrels and 3 used barrels) and 1000 liter American oak barrels (3 new barrels and 3 used barrels). [Pg.24]

In Germany, arsenicals such as Lewisite, Adamsite, Clark I and II, Sulphur- and Nitrogen mustards are destroyed by a special incineration method. Agents are drained into polyethylene barrels and incinerated directly at 1000°C [2]. Arsenicals are precipitated out of the incinerator scrubber water as FeAs04. The arsenic sludge is buried in drums in a waste dump (former salt mine). Since operation began in 1980, 73 tonnes of concentrated chemical weapon agents and 600 tonnes of contaminated materials have been destroyed. The cost estimate for Sulphur mustard is about 100 DM/kg. [Pg.130]

In theory, the antidigestive properties of Pi s combined with the above enzyme-based defenses should provide "double-barrel negative resistance, since the first increases the need for sulphur amino acids, and the second has the potential to decrease the availability of these and other amino acids. However, in order to jointly utilize these two defenses effectively, a deeper knowledge of their chemical interrelationships is necessary. Potential complications in the use of proteinase inhibitors will be discussed below. [Pg.173]
