What is presented is a high power igniter comprising an igniter housing adapted to be positioned in a conduit. The igniter housing comprises a containment sub and a nozzle sub that releasably secure to each other. A high wattage heater located in the igniter housing comprises a combustible pellet insertable into the igniter housing for creating a flow of heated gas when the combustible pellet is ignited with a pellet igniting device while the high power igniter is in use. The high power igniter is free from a loose powdered form of combustible material when the combustible pellet is in the igniter housing. The nozzle sub directs the flow of heated gas in the system.

What is presented is a metal magnalium thermite pellet that is used to create heated gas. The metal magnalium thermite pellet is made to be inserted into the cutting apparatus that is used for cutting a conduit for oil, gas, mining, and underwater pressure sealed tool applications. To cut the conduit, the cutting apparatus radially projects a flow of heated gas from the internal surface of the conduit through to its external surface. The metal magnalium thermite pellet is also made to be inserted into the high power igniter that releasably secures to the cutting apparatus. Generally, the metal magnalium thermite pellet comprises a metal magnalium thermite composition that consists of between 1 to 44 percent magnalium alloy, 1 to 44 percent aluminum, 40 to 60 percent iron oxide, and 10 to 20 percent polytetrafluoroethylene.

What is presented is a combustible pellet for creating heated gas. The combustible pellet can be inserted into a cutting apparatus or a high power igniter or both. The combustible pellet is compacted to be resistant to mechanical damage, resistant to unintentional ignition, and free from a loose powdered form of combustible material when ignited in the cutting apparatus or the high power igniter. In certain instances, the combustible pellet is compacted to between 90 percent and 99 percent of its theoretical density. The combustible pellet may be capable of being transported separate from the cutting apparatus or the high power igniter or both. The combustible pellet may also be capable of being stored separate from the cutting apparatus or the high power igniter or both. The combustible pellet may comprise a circular cross-section and tubular length. The combustible pellet may comprise an axial hole.

Compositions, devices, and methods for destroying chemical warfare agents, independent of their chemical make-up, include (i) at least one reactive metal; (ii) at least one oxidizer; and (iii) a binder. In one embodiment, the self-sustaining reactive composition includes magnesium powder, iron oxide powder, potassium perchlorate powder, and silicone gel. In another embodiment, the self-sustaining reactive composition includes manganese powder, lithium perchlorate powder, lithium peroxide powder, and silicone gel. The reactive metal(s), oxidizer(s), binder, and their respective amounts, are selected such that, following ignition of the composition, the composition is capable of producing a solid mass of ash (wicking composition) that increases the surface area of the chemical agent material and provides a site for combustion and/or thermal degradation of the chemical agent to occur.

An igniter composition has (i) a source of copper selected from basic copper nitrate, copper oxide, copper hydroxide, and/or copper complex of guanylurea nitrate, (ii) one or more oxidizers, (iii) a binder selected from guanidine nitrate and/or guanylurea nitrate, and (iv) an inorganic fuel comprising an elemental metal or metal hydride selected from the group consisting of: titanium, silicon, aluminum, magnesium, iron, and combinations thereof. The igniter composition may be substantially free of boron or contain minimal amounts of boron. A minimum flame temperature at combustion (T.sub.c) of about 2300K (2,027 C.). Such a mixture may be spray dried to form a powder that is compacted to form a solid igniter composition, such as a pellet or grain. The mixture that is spray dried may have a heat of explosion (HEX) of about 1,000 calories per gram (cal/g). Inorganic fuel can then be added to the spray-dried powder.

The invention is a multi-layer thermite block, encased in an exterior protective shield with one face exposed. The exposed face is carved out to accommodate a target device such that the block encompasses the target device when placed atop the device. When receiving a data-destruction signal, the block is ignited producing a short-duration blast of heat sufficient to severely damage or destroy all physical data-storing facilities of the target device.

This present invention is directed to a powder comprising a composite of primary nanoparticles of aluminum and/or aluminum oxide, the nanoparticle being separated from the others by an intervening organic or polymeric material, and formed into secondary particles that are substantially larger than the primary nanoparticles.
