Abstract: The invention disclosed relates to a foam-forming composition, for suppression/containment of blast from explosive devices. The composition comprises, a) a surfactant 40-80% w/w b) a foam stabilizer 0-7% w/w c) a polyalkylene glycol 10-30% w/w d) water, balance to 100%.

Abstract: The invention disclosed is an apparatus for explosive blast suppression, and a method therefor, the apparatus comprising a hemispherical enclosure (10) defined by an upstanding wall, positioning means (42) associated with the enclosure, for positioning the explosive device substantially equidistant from any point on the wall, and in a preferred embodiment includes an integral floor (40) and a rounded lower wall, to provide a substantially even distribution of blast forces in all directions toward the wall. The enclosure is made of composite textile material, comprising one or several layers of a ballistic material (e.g. Dyneema Kevlar) sandwiched between inner and outer layers of a light-weight rip-stop nylon fabric material.

Abstract: A foam generating nozzle is disclosed comprising a cylindrical housing, a first inlet at one end of the housing for connection to a supply of foamable liquid under pressure, a second inlet at the first end for air supply, a foam discharge outlet at the other end of the housing, a diffuser associated with the first inlet and a conical screen of a non-corrosive material disposed in said housing between the ends with its apex directed toward the discharge outlet, to provide a screen surface area larger than the inlet air supply area, such that in operation the foamable liquid is sprayed onto the screen by the diffuser in a pattern which matches the conical shape of the screen, while air is dragged through the screen thereby generating the foam.

Abstract: Compositions and methods for retarding and extinguishing forest fires and ground fires by dropping air-activated foam compositions comprising 1% to 80% hydrocarbon surfactants, 0.1% to 6% by weight foam stabilizers, 0% to 30% by weight of solvents and 1% to 98.9% by weight of water.
