International Classification:

F42B 1244

US Classification:

102364, 102311, 89 113, 86 50

Abstract:

The various embodiments provide an incendiary device utilizing a multiple hollow core-burner technique that facilitates producing large diameter cuts through steel targets. To facilitate this result, the various embodiments incorporate a multiple-core burning design with multiple orifices at the base for directing multiple jets of molten reaction product at the target. The various embodiments further incorporate an optional holding device as a means for locking the device onto a target. Devices in accordance with the invention having a base diameter of 2. 312â have been shown to be capable of producing an approximately 2â diameter hole through  inch thick steel plate using a 275 g thermite charge within a container three-quarters the size of a standard AN-M14 Thermite Grenade package.

Gene V. Tracy - Bel Air MD

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

C06B 2910

US Classification:

149 83

Abstract:

The present invention is an essentially non-toxic, smoke-producing, pyrotnic composition. The composition uses 1,4 benzenedicarboxylic acid which produces a superior visual screening smoke when vaporized by heat provided a reaction between suitable fuel and oxidizer. The composition additionally contains potassium chlorate and sugar. The composition burns at a low temperature without a visual flame and is suited for use in smoke grenades and smoke pots.

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

C06B 2910

US Classification:

149 84

Abstract:

This invention relates to a smoke-producing composition containing a dye 1,4,- benzenedicarboxylic acid. The acid is useful for purging slag and solid clinker while lowering the steady state burning temperature of the composition. The coloring agent used by the composition does not degrade. The acid is an efficient coolant for the composition and takes advantage of sublimation reactions to produce the properties enumerated here.
