Miner s Squib (PSjtard de Mineurs). One of the primitive devices which was invented by Daddow in Engl in 1874 for igniting blasting expls. It consists of a tapered paper tube, about 7 inches long, filled with fine gunpowd. One end of the tube is filled with chemicals, such as milled gunpowd mixed with either sulfur or sulfur and charcoal, so as to form a sort of slow match. 

A little gunpowd is added at the end in order to facilitate ign of the slow match. When used, the squib is inserted with the slow match outward in a hole made in a charge of BkPdr blasting expl. When the match is lit, the fire burns slowly, allowing the miner time to reach a place of safety. As soon as the fire reaches the BkPdr core of the squib, it burns fiercely and then suddenly explodes, igniting the blasting expl. Instead of the paper tube, quills filled with fine BkPdr joined to a slow match, can be used... 

Muraour, Henri (1881—1954). Fr scientist, a specialist in expls (Ingenieur general des poudres) and ballistics. Published more than 200 papers from WW1 thru 1952 (Ref 2) on expls, proplnts, combstn of proplnts, expl phenomena, antiflash agents, purification of TNT, theory of expl reactions, etc, as well as a widely read book (Ref 1)... 

Nitramindine. Expl compd prepd in 1845 by Dumas by the nitration of paper or cardboard, and proposed for use in the manuf of cannon cartridges (gargousses in Fr). This material was prepd prior to the discovery of NC by Schbnbein Ref Daniel (1902), 453... 

Paraffin is also used for impregnating paper used for cart ridging expls, as well as moisture proofing paper cartridges already loaded with hygroscopic Dynamites... 

Also, friction has caused the expin of an NH4 peroxodisulfate/Na202 mixt (Ref 8). Spont ign has occurred upon mixt or contact of Na202 at RT with mats such-as moist cloth, paper or wood (Refs 3 16) H2S or various peroxides (Ref 8) C02 or metallic Na (Refs 6 9) non-metal halides (Refs 8 9) org liqs (benz, eth, aniline, etc) and w (Ref 3) and AgCl and charcoal (Ref 7). Percussion has caused spont ign of mixts of various org mats with NaOH or KOH and Na202 (Ref 17). Percussion has also caused spont ign to occur when Na202 is mixed with mats such as hay, bark, cotton or powd S (Ref 17). When Na and Na202 were heated together to the mp of Na (97.7°) under Ar, expl ign has also occurred (Ref 15)... 

Cole (Ref 1) described methods and presented data for measuring the underwater effects of expls. Price (Ref 3) suggested that the underwater effectiveness of an expl can be indicated by the sum of its shock wave and bubble energy equivalent wts (in her paper relative to 50/50 Pentolite). In Table 2 we compare such indices of underwater performance (but relative to TNT rather than Pentolite) with relative heats of detonation. We used 1.09kcal/g for the heat of detonation of TNT under the assumption that... 

Pyropaper (Pyropapier or Papier Fulminant in Fr). An expl prepd by plunging unglazed paper into a mixt of nitric and sulfuric acids for 2 minutes. After submitting the paper to the usual process of stabilization and drying, it was cut into small pieces and used in primers for needle rifles (fusil a aiguille in Fr) (see in this Vol, N22-R)... 

Accdg to Roth (Ref 4) the geometrical theory is essentially the theory developed by him and described in his thesis (Ref 1). Roth also pointed out that this theory is mentioned in a paper by Wohler Roth (Ref 2) who also made use of the surface-erosion concept in describing reaction rates in the deton of expls. Roth lacked the necessary proof at that time to justify exploitation of his theory... 

NinthSympCombstn (1963). The following papers dealing with initiation of expls were presented at the Symposium ... 

The paper surveys published work on detonation limits, correlates the data with other props, reviews theories on the subject, and seeks a coherent overall view. It is assumed that at the limit the deton snock strength becomes critical for initiation of reaction. The critical shock pressure is therefore a significant quantity to examine. Data obtd for ten expls (TNT, AP, EDNA, DNT, AN, Ammon Dynamite, AN/Oil, AN/... 

Ethyl Nitrate 2572, Diazodinitrophenol 3087 and 1,1-Dinitropropane 2543 C Note In the report (as well as in many other papers and reports) these temps are called "explosion temperatures . As this term can be confused with temp to which.an expl must be heated to induce expln, we prefer "temperature of explosion when it. concerns "temperature developed on explosion ...

The construction of flash type detonators is similar to other detonators. Each flash type detonator consists of a metal capsule contg a chge of expls. The capsule, which is usually of A1 (on account of presence of LA as an expl ingredient in US Army and Navy flash detonators) may be closed with paper or thin A1 disk, as indicated in Fig... 

Tokyo International, Tokyo, Japan. The paper contains nearly 100 entries and 30 refs of which only 4 are Western. The entries are arranged in chronological order. Mr Gunther Cohn of Franklin Institute reviewed the paper in Expls Pyrots 5 (11), 1972...

Test tubes, each contg O.lg of a NC expl, are suspended in a bath of mineral jelly preheated to 100°. A strip of Kl-starch paper is suspended above the sample. Heating of the bath is continued, by raising the temp 5° per min, until the point is reached at which the test paper begins to color. This point is taken as an indication of the stability of the NC proplnt.
