The present invention is directed to a novel, low-toxicity red smoke generating composition and a method of making the same, comprising at least one red dye, a coolant, an oxidizer, a non-sugar binder, and a non-sulfur particulate fuel that is also a burn-control agent having at least one particle size distribution. Preferably, the red dye comprises an anthracene or anthraquinone-based dye and the fuel comprises a sugar or mixture of sugars.

Low toxicity, environmentally friendly red smoke generating composition and method of making the same

The present invention is directed to a novel, low-toxicity and environmentally-friendly violet smoke generating composition. The composition comprises a mixture of at least one red dye and at least one blue dye, a coolant, an oxidizer, a binder, and a non-sulfur particulate fuel that is also a burn-control agent having two different particle size distributions. Preferably the fuel comprises a mixture of granulated sucrose and sucrose 10&#xd7;.

Low toxicity, environmentally friendly violet smoke generating compositions and methods of making the same

An incendiary device such as a grenade includes a fuze; a fuze bushing operatively connected to the fuze; a first plate snap fit to the fuze bushing; a delay column pressed into the first plate; a drag adapter partially surrounding the fuze bushing and contacting a top of the first plate; a burster tube operatively connected to the first plate; a second plate operatively connected to the burster tube; and a housing body screw fit to the first plate and the second plate and surrounding the burster tube, wherein the first plate and the second plate are epoxied to the housing body and the burster tube, wherein the fuze is configured to initiate causing gases and sparks to be released between the fuze bushing and the first plate, wherein the gases and sparks increases a pressure causing the fuze and the fuze bushing to be ejected from the housing body.

Non-lethal obscuration grenade

A composition of matter for an incendiary device includes a thermate component consisting of strontium nitrate Gr A, black iron oxide Gr B, aluminum Gr D Cl 5, aluminum Gr E Cl 6, sulfur Gr E, and polyacrylic rubber; and an ignition component consisting of potassium nitrate, titanium, aluminum, silicon, sulfur, charcoal, and polyacrylic rubber, wherein the thermate component consists of a barium nitrate free thermate formulation, and wherein the ignition component consists of a lead free ignition formulation. A parts by weight composition of the thermate component consists of 20.59% strontium nitrate Gr A, 48.04% black iron oxide Gr B, 17.57% aluminum Gr D Cl 5, 9.88% aluminum Gr E Cl 6, 1.96% sulfur Gr E, and 1.96% polyacrylic rubber, and a parts by weight composition of the ignition component consists of 66% potassium nitrate, 11% titanium, 8% aluminum, 6% silicon, 2% sulfur, 5% charcoal, and 2% polyacrylic rubber. Preferably, the first and second components are consolidated together using a ram having a sharp-edged profile.
