Abstract: This invention relates to improved desensitized dynamites, the improvement comprising the incorporation of a desensitizing compound selected from the class of compounds known as diesters, polyesters, triesters except those esters containing benzyl rings, and dialkyl substituted amides or combinations thereof.
Abstract: A process is disclosed for preparing a gelatine explosive composition comprising the steps of adding at least one dispersing agent to a mixture of liquid nitric esters and ortho-nitrotoluene, adding the resulting mixture to blasting soluble nitrocotton to form a gel and subsequently adding oxidizing salts, fuels, and when desired, a water-proofing agent such as tamarind seed flour or guar gum to form a homogeneous mixture.

Abstract: A novel ballistic modifier complex is produced by mixing and interacting an rganic isocyanate with lead beta resorcylate and cupric salicylate in an inert solvent. The complex product obtained after removal of the solvent, when incorporated into a nitrocellulose-nitroglycerine double base propellant, yields a propellant composition of excellent ballistic properties and improved stability against development of exudate which inhibits ignition.
