Ignition device

Internal combustion engines contain several features that pose ignition sources for hydrocarbon vapors. Most obvious is they exhaust hot combustion gases that can ignite vapors, secondary they have hot surfaces - primarily the exhaust manifold and piping, and finally and most overlooked, instrumentation and ignition devices may not be rated for use in an area where combustible gases may be present.

Solar Cells—Some nanotubes exhibit a photovoltaic effect and can replace material in solar cells acting as a transparent conductive film allowing light to pass to the active layers and generate photocurrent. It has also been shown that nanotubes can be used in conjunction with other materials to act as an ignition device that is triggered with a simple camera flash. 

Misch metal, an alloy of cerium with other lanthanides is a pyrophoric substance and is used to make gas lighters and ignition devices. Some other applications of the metal or its alloys are in solid state devices rocket propellant compositions as getter in vacuum tubes and as a diluent for plutonium in nuclear fuel.

Many chemical ignition devices have been used in sabotage devices and many of them were described by Stettbacher (Ref 18, pp 130-32 Ref 21, pp 164-66 and Addnl Refs Ad 34a Ad 52a). Ellern (Ref 57, pp 48-52) describes some chemical reactions which can be used in sabotage devices and on pp 216-23 are listed several fire starting and fire setting devices, some of which can be used as sabotage incen-diar ie s...

Accdg to Refs I R, Japanese Rocket Launchers were mostly wooden troughs, others were guide rails and steel barrels (tubes). Launchers were provided with some electric ignition device. The most practical launcher was used by the Japanese Army under the name Type 4 20-cm Rocket Launcher, described in Ref 1, p 204 and shown in Fig 320 on p 206. It consisted fo a metal tube on a mounting permitting fine adjustments in elevation and train. The launcher was in three parts which could easily be disassembled for transportation. A rate of fire of from 1 to 2 rounds per minute could be obtd... 

The rocket consists of a rocket motor (which also acts as a combustion chamber on ignition of solid propellant) with a nozzle on one end and an ignition device on the other end. (Figure 1.4)... 

IV. Rocket Ammunition is fired from a device called a "launcher, such as the "bazooka of WW II fame. Rocket launchers consist of either guide rails or guide tubes fitted wich some electric ignition device.

Chemical Fire Starters Devices intended for starting fires under adverse climatic conditions, such as in wet jungles or on snow -covered terrain. The Ml fire starter is a cylindrical NC container 1.25 in diam by 3.25 in length filled with 0.8oz of kerosene thickened to a gel and provided with an ignition device, consisting of a match-head attached to a disk which covers the filling. A scratcher is attached inside a metal cap which covers the match head of the fire starter. The cap is fastened to the container with adhesive tape(Ref, pp 51-4 ...

Timely ignition is critical, so there is a need for immediate or continual activation of the system being used. Devices that can be used for remote ignition include flare pistols, electric ignition devices, and propane burners. The location and spacing of the devices are typically functions of the material and facility however, it is critical that a release does not go undetected by the gas detectors (if there is no continual ignition source) or by the ignition system itself. 

The most attractive monopropellants are those whose exothermic reaction or decomposition can be catalytically initiated. The employment of monopropellants requiring thermal ignition results in the undesirable addition of an ignition device to the propulsion system. The recent development of a low temperature catalyst for the decomposition of hydrazine has made hydrazine and hydrazine based compounds among the most attractive monopropellants for propulsion purposes. 

Not all was lost. The process provided valuable instruction relative to ignition devices, bridge wires, drop wires, insulation, and crimping. In an attempt to hold all variables to an absolute maximum, wc did not try to make more than one component at a time, and no experiments were done with match-lit fuze and cap systems. Safety fuze is extremely difficult to make at home, and a successful electric cap could always be changed over to safety fuze if necessary, we reasoned. In the course of the discovery process, we were able to expose a great many fables and old wives tales regarding detonating explosives.
