Definitions
- compositions of metal-free initial explosives or of explosives which contain the same metal as that of which the material to be riveted consists were compositions of metal-free initial explosives or of explosives which contain the same metal as that of which the material to be riveted consists.
- the known purely organic initial explosives are quite out of the questionfor this largescale use, since they are far toosensitive and partly also are not stable to'storage, for example, nitrodiazobenzene perchlorate and cyanuric triazide.
- the mannite hexanitrate is mixed with about 30% tetrazene, then on heating in the rivet this mixture detonates' with the high starting velocity'peculiar to initial explosives and with high shattering power. Peculiarly enough, this action occurs only on uniformly heating the whole quantity of explosive in the rivet and not with flame and spark ignition, which at best leads only to a burning away of this explosive mixture. This property is very remarkable and is fundamentally important from a technical point of view, since this composition affords a great degree of safety from accidental explosions, both in the case of the loose composition as well as in the'case of the finally charged rivets.
- silver, copper and aluminium powder be raised up to about of the mixture, without the detonation sensitivity and the high starting velocity being eral, initiated at one end and does not travel layerwise through-the explosive charge but takes place practically at the same moment at all points of the charge, there is an increase in the "starting" velocity and a shortening in the time of detonation.
- the braking eiTect of large quantities of inert substance is completely compensated for by this new eflect and the action of the detonation is made still more uniform by the increased decomposition velocity.
- mannite hexanitrate may also be replaced by the nitrates of tetrabasic and pentabasic alcohols, e. g. by erythrite tetranitrate.
- the present invention therefore represents a noteworthy advance over the pure initial compositions sensitive to flame, impact and friction heretofore proposed and used.
- an explosive charge comprising a nitrate of a solid polyvalent alcohol containing between 4 and 6 hydroxy groups, and guanylmitrosamino guanyl-tetrazene.
