Abstract: The invention disclosed is a floating incendiary device adapted to be dropped from an aircraft onto a combustible material on a body of water. The device includes an incendiary composition in the form of a disc which is ignited peripherally and burns inwardly. The incendiary composition is sandwiched between a pair of discs which direct the resulting flame radially outwardly over the surface of the combustible material during the burn time of the incendiary composition for a time sufficient to raise the temperature of the combustible material to its fire point to produce ignition and selfsustaining combustion of the combustible material.

Abstract: The invention disclosed is a floating incendiary device adapted to be dropped from an aircraft onto a combustible material on a body of water. The device includes means for directing the resulting heat by convection and radiation to concentrate on a particular area of the combustible material for a time sufficient to raise the temperature of the combustible material to its fire point to produce ignition and self-sustaining combustion of the combustible material. A novel incendiary composition for use with the device is also disclosed.

Abstract: A method of coating an organic dye composition with an inert coating material, such as an epoxy resin, is disclosed which improves the mechanical properties of the organic dye particles and enables the production of pour-castable colored smoke-producing compositions of high solids loading.

Abstract: This invention relates to organic dye compositions of improved mechanical properties and to a method of coating the dye with an inert coating material which enables the production of pour-castable colored smoke-producing compositions of high solids loading, particularly when a red dye e.g. Disperse Red 9, is employed.
