1'0 will whom it may concern:

Be it known that I, Anonru FRANK, e subjeot of theKing of Prussia German Emperor,

residing Eerlinerstresse' 26, Ulinrlottem burg, Germany, have invented and useful Improvements in Explosive Compositions, of which the following; is e specification.

The present invention relates to the use of oysnsmids-el 0., eyanemid, dicyandiumicl;

tricyentriemid (melemin), the suits of the said substences with acids or motels for the manufacture of explosives and the explosives containing oysnumids. The object of the said use of the oyansmids consists especially in reducing the temperature of the gases formed by the" detonation of the explosives without diminishing the propelling or blasting power of the explosive. in explosives, as smokeless powder of nitrocellulose or a mite ture of nitroglycerin end nitrocellulose, by the addition of c'ysnemids the temperature of the gases formed by the detonation is dimln; ished, whereby an injury made by the detona'tion to the guns is entirely avoided ordiminished. In mining-explosives the infium motion of fire-damp is avoided by the said sch-- dition of cyunamid or cysnnn iids and e greet safety against mining accidents is obtained. According to the present invention genen ally cynnamids or it sm ls eyansmid or salts of the cyunamids, with acids or metals, may be added to every substance or mixture of sub stances which are capable to be detonated.

- In the following the present invention is de scribed in the Way of example in the use for explosives containing; substances being shleto give oii' oxygen by their decomposition or Cysnernid having the formula. filihlg, dicyendiemid' having the formula Calishh, tricyentrismid (melarnin) having; the formula CnlisNoCOlltillD in hundred parts 28.572 parts carbon, 4.762 parts hydrogen; 66.666 parts compounds to carbon monoxid one atom of oxygen is required for each atom of carbon. One may however, conduct the combustion so that completely or newly-completely osrluon dioxid 13 formed in oxidiz ng dioy'sndiemid according to the equation witl'iont unyrerneinder Irena-one i lent--i. a, from ei ity iour eruid shout-one drool e' d thirty gases are formed e, om one h sixteen. hundred liter w u yenon we liter .o' about .r the addition of L243 kilo eight hundl 1 1 oxygen is required. Prefereblythe sired addition ofoxygen outed bymini eyesumid (dioyendio,mid trieyentristnid} r salts in it suitable proportion with on capable of yielding its d tion. Such salts are, for 'instnnoe, n chloretes, perchlorstes, mengenetee, gene-tee; chrometes'perchrornetes of the elitelies; earth slkulies. or motels, finesse also use any suitable oxygemyieldi 0X"i(i -f0? instance, peroxi One use single salt or oxid or s, mixtureof suits or oxide orperoxids and even e mixture of salts end oxide.

@f the nitrates one may prefeznoly use niof ammonia, Z ne rosy however use any othes nitrate, organic or inorganic. It nitrous acid may be evolved in the explosion 'it is suitable to use more eyenemid (dicysndiemid, tricynntrismid) than Y be oxidized by the oxygen evolved. One em ploys such amount of cysnsmid (dicyendiernid trioyentriamid) that diszo compounds may be formed by the notion of the nitrous acid ongth'e cysnemid (dicyendismid, tricya-ntriumid) may not as s cyanogen guenidin, which is converted by combining with water into guefnylures sud by eornbiningr, with em monis into'big nsnid. The amide groups will be diuzotized by the nitrouseeid evolved in the explosion. "The diezo compounds have a peculinrvelocity of decomposition, which is very useful for the power of the explosive and avoiding en increesing of temperature of ex- @losion. Une uses with ammonium nitrate es oxidizing sgent a larger amount of cyenarnid q, osii'osi $42., e niiouiug proportions: live 0 iifl (or di. mid, tri inety-live to e k Live parts Ill uzu, (ornpproprinle proporum, sodium, lmriuni, calcium,
