Not illustrated. 1917 edition. Excerpt: ...to superimpose a small charge of fulminate, its chlorate mixtures, or lead hydronitride, upon organic nitro compounds or nitrates in the detonator shell. The detonator is usually of the "reinforced" type, (fig. 1) in which an inner perforated shell is pressed down over the charge. The sensitive fulminate composition, fired by fuse or electrically, detonates the secondary explosive, thersby transmitting the impulse that causes the blasting explosive to detonate. Priming charge v Reinforcing cap This plan of superimposing an initial primer upon a secondary explosive in a detonator shell offers an excellent arrangement, not only for practically working out the best combination for commercial detonators, but for studying theoretically the process involved in the transmission of the detonating wave from the initial primer to a secondary explosive, and has been used by several investigators." USUAL METHOD OF PERFORMING DETONATION EXPERIMENTS. The experiments are usually carried out by weighing into the copper shell a fixed quantity of explosive (trinitrotoluene, pricric acid, guncotton, or the like), and varying the weight of primer until the minimum quantity required for certain detonation is ascertained. It is obvious that the method may be used either to compare the relative sensitiveness of explosives toward the same primer, or the relative efficiencies of different priming compositions in detonating the same explosive. a See Wohler, L., and Matter, O., Beitrag zur Wirkung der Initialziindung von Sprengstoffen: Ztschr. ges.
