Abstract: A frangible projectile, and weapon cartridge containing same, is provided, in which the frangible projectile is comprised of a hollow outer body composed of, for example, a plastic or polymeric material, configured to provide a payload material. Preferably, the hollow outer body has an interior surface having a divider formed or disposed therein, for controlling the movement of the payload material after firing. The hollow outer body of the frangible projectile, upon impact, rapidly fragments upon impact into relatively harmless pieces, and releases/mixes the payload material. However, the payload material may be chosen to provide sufficient mass, and accordingly sufficient kinetic energy, to provide desired target effects, such as powder metals. Alternatively, payload materials, such as reactive chemical components, marking agents, chemiluminescent compositions, incapacitants, multi component reactive compositions, etc., preferably contained within one or more payload containers, are provided.

Abstract: A method of preventing initiation of an explosive device. The method comprises substantially encasing an explosive device with a conductive foam. The explosive device is configured to be initiated by an electromagnetic radiation signal, such as that emitted by a transmitter of a wireless door bell device. Deactivated explosive devices are also disclosed.

Abstract: A fuel-storing ordnance canister for release from military aircraft that does not explode upon impact, its collapsible accordion-like structure instead forcefully dispersing atomized fuel in an upwardly direction in the impact zone after descent for dispersal in, around, and beyond the impact zone. When the fuel from multiple canisters is released into a drop zone and later ignited by a dropped or ground-based incendiary device, all life in the dispersal area is eliminated. Tail fins assure nose-down flight and provide handles for easy canister handling and loading onto airplanes. The configuration of a pop-open tail plug allows for its partial release upon canister collapse to create a spray nozzle that atomizes the fuel stored in the canister as it is being dispersed. The most preferred application is by the U.S. Military to eliminate terrorists hiding in caves, hidden ordnance, and other areas previously resistant to air-released ordnance.

Thus the incendiary 10 is in the form of a flexible belt having a plurality of containers 12 which are mutually held together until separated by a dispensing/initiating machine. Each container 12 includes a flat surface 22 and a receptacle 18 having an opening 20 which opens onto the flat surface 22. A seal 24 extends across and closes the opening 20.

Abstract: A gas-phase warhead for use against a hardened and deeply buried target containing a payload that is ignitable when combined with air. After the warhead is delivered near an air intake of a target, the payload is expelled from the casing of the warhead in a slow, controlled manner so as to allow the formed payload-and-air mixture to infiltrate the areas of the target. After a predetermined amount of time, the payload-and-air mixture is ignited and a detonation or a deflagration within the target occurs.

Abstract: A method for creating coherent masses of burning matter for countermeasures purposes such as for protecting an aircraft and other vehicles from infrared “heat seeking” hostile missiles and also from high power Laser beams and Laser radar. One or more spurious sources of radiation are created controllably in the general vicinity of the aircraft being protected; in missile countermeasures, each of these spurious sources is capable of emitting infrared energy comparable in wave length and at a higher intensity than that emitted by the target aircraft itself such that the hostile missile will be decoyed away from its intended target by the spurious radiation sources. In this method, the spurious source of radiation is created by igniting a small amount of aircraft fuel that is gelled and controllably ejected from the aircraft.

Abstract: An aerial fireworks display device includes a plastic bottle for holding a quantity of combustible liquid, such as diesel fuel, and a one piece plastic lid structure which is threadable onto the bottle and has an open-topped depending well portion in which a quantity of flash powder may be placed. After the flash powder has been placed in the lid well portion a fuse-containing plug structure is snap-fitted into the top end of the lid well. The diesel fuel is poured into the bottle and the lid is screwed onto the bottle so that the flash powder-containing well extends into the bottle interior, and a portion of the fuse extends outwardly through the upper end of the plug structure. The assembled device may then be inverted and placed in a mortar tube for launching.

Abstract: The invention relates to the chemical initiation of detonation of a fuel-in-air (FAE) cloud such as might be used in a minefield breaching system. A component of the system is adapted to carry fuel to the breaching site and is also adapted to carry a compatible chemical, either gaseous or liquid. Upon detonation of a suitable explosive within the component the fuel is dispersed outwardly to form the cloud and the chemical is jetted outwardly into the cloud in a turbulent manner. A chemical reaction between the chemical initiator and the fuel-air mixture leads almost instantaneously to an explosive shock wave that propagates through the cloud causing detonation thereof. Such detonation neutralizes the minefield along a desired path. With the invention it is not necessary to utilize secondary charges and hence a more efficient and reliable breaching system is achieved.

Abstract: An arrangement for propelling liquids over long distances involves enclosing liquid in a plurality of thin plastic spheres having a dimpled surface. The liquid containing spheres are propelled over substantial distances by shooting them from a pipe by means of compressed air.

Abstract: A fuel composition in the form of a gel is particularly adapted for use in a fireplace or a heater and offers the advantages of increased stability, reduced burn rate, decreased noxious by-product generation, and enhanced safety. Comprised of a combination of water, alcohol and ethyl hydroxyethyl cellulose, the miscibility of these components is accomplished by lowering the pH of the mixture. Once in solution, the pH of the mixture is then raised to increase its viscosity in forming a stable gel. Various low carbon alcohols, or blends thereof, may be utilized to provide a range of combustion characteristics. In addition, various salts may be incorporated in the stable gel fuel to provide a desired flame characteristic.

Abstract: An air burst munitions simulator which provides for the aerial dissemination of readily dispersable substance.
