  • Patent number: 5425311
    Abstract: A hybrid fuel-air warhead having a housing containing a cylindrical body of reactive liquid surrounded by a housing containing a cylindrical body of reactive dust. A means to burst the two housings is provided along with a number of disks and end caps used to facilitate the turbulent mixing of the reactive liquid and reactive dust and to provide control of the cloud height.

  • Patent number: 5386778
    Abstract: A process for visualization of a blast wave, which is the shock wave resulting from an explosive charge, is practiced by observing disturbance contours on a liquid-air cloud and interpreting resulting graphical and calculated data to evaluate matters related to the explosive blast wave.

    Inventor: John D. Sullivan, Jr.
  • Patent number: 5331896
    Abstract: Steps of a process for visualization of a detonation wave involve examini measuring, and confirming a fuel-air explosion by using a ground-based fuel bottle oriented horizontally whereby the explosive dissemination creates a fuel-air cloud with its diameter in the vertical plane and a timed delay, proximate charge explodes within the created cloud. A ground-based high speed camera with a line-of-sight, end-on position with respect to the bottle, photographically records the existence of any occurring detonation wave.

  • Patent number: 4892597
    Abstract: A liquid explosive composition having a density of about 1.282 grams/millter and comprising a mixture of (a) nitromethane, (b) trinitrotoluene, and (c) pyridine. Said ingredients being present in a weight ratio of about 60-64 parts nitromethane; 34-29.5 parts trinitrotoluene; and 6-6.5 parts pyridine.

  • Patent number: 4815385
    Abstract: A blast focusing technique for producing high pressure on a ground plane, in which a right circular cylinder of explosive material is positioned adjacent the ground plane with the cylinder axis orthogonal to the ground plane. The cylinder is simultaneously detonated at both ends by detonators disposed on the cylinder axis at each end of the cylinder.

  • Patent number: H161
    Abstract: The invention comprises a plastic bottle having a threaded cap with a hole n its center and two hollow plastic tubes having the same diameter. One of the hollow tubes is empty and is used to seal the device in transit. The other hollow tube is filled with an explosive fluid and capped with a detonator with wires that connect to a power source. The device is designed to create a volatile mist of air and combustible fluid by dispersing the combustible fluid by means of an explosive charge. The explosive charge is made up of an explosive fluid and is an integral part of the device. The device can be manufactured from commercially available, inexpensive materials and requires no skill or tools. The device can be safely operated. It is made entirely of plastic materials; there is no metal which may fragment.

  • Patent number: H162
    Abstract: A system and method for wide-area mine clearance employs a plurality of f-containing plastic containers disposed a horizontal distance apart which permits an overlap between adjacent aerosol clouds formed therefrom when explosive bursters are simultaneously detonated within each container. At least one detonation charge is exploded within one of the aerosol clouds following a predetermined time delay for detonating the line of overlapping clouds whereby a line of ground surface is exposed to a fuel-air explosion capable of detonating susceptible mines therein. The distance between adjacent containers and the height each container is suspended above the ground is related to the weight of the liquid fuel contained in each container. In the preferred embodiment, each plastic container is suspended from a tripod having a hook or other means for permitting attachment and detachment of a crane hook whereby the tripod may be positioned over uncleared ground from a location well within cleared ground.
