Obturated Gasless Delay Element

Another example of obturated gasless delay element is the one used in pyrotechnic items and shown in Ref 54, p 5-32) (See Fig 1-60) 

Following is the list of gas less delay compositions given in Ref 54, p 5-34, Table 5-13 and p 5-35, Table 5-14 

In Table 5-20, p 5-40 of Ref 54 are given compositions of ignition powders for gas less delay elements 

In Table 5-29, p 5-49 of Ref 54 are given some first (ire, starter and igniter compositions 

Delay trains used in pyrotechnics are described in Section 4, Part F
