| 181 | Line charge insensitive munition warhead | US944049 | 1997-09-12 | US5932835A | 1999-08-03 | Robert Woodall; Felipe Garcia; Gilberto Irizarry |
| A warhead has a pair of shells, each having an annular rim at one end and opening at the other end. The rims abut one another and are fastened together to define a chamber filled with explosive having a bore aligned with the openings. The explosive has sensitivity to detonation that requires axial detonation in the bore by a detonating cord to initiate explosion thereby preventing detonation by lesser stimuli. A tube extends through the openings and bore and is sized to receive the detonating cord. Opposite ends of the tube are crimped to hold the shells together. A line charge provided with a plurality of such warheads has significant pressure, shock, fragmentation energy, wire cutting ability and mine neutralization capacity as compared to contemporary devices. These improved capabilities are directly attributed to the explosive type and density of this design. In addition, the materials selected for fabrication have the appropriate toughness hardness, and thickness to generate these capabilities upon detonation of the explosive. When tested against anti-personnel mines and wire obstacles, this lightweight design was efficient and effective. Furthermore, as an added feature, this warhead was found to comply with all insensitive munitions requirements. | ||||||

| 187 | Explosive auto-enhancement device | US185076 | 1980-09-08 | US4372214A | 1983-02-08 | Edward T. Toton; Elihu Zimet |
| An explosive auto-enhancement device for providing higher detonation pressure than can be achieved with conventional explosives by the use of magnetic precompression for enhancing the detonation wave. A cylindrical armature containing an explosive charge is coaxially spaced within a helical field generator winding with a first end of the armature being electrically coupled to the helical winding. A "seed" magnetic field is provided to the helical winding prior to the initiation of the explosive charge. When the explosive charge is initiated, forming a detonation wave, the other end of the cyclindrical armature expands and is coupled to the helical winding, thus completing the electrical circuit between the winding and the armature. As the detonation wave continues through the explosive charge, more of the coils of the helical winding are short circuited which reduces the inductance and results in increased magnetic flux within the winding. A magnetic pressure appears ahead of the detonation wave due to the increased magnetic flux and compresses the undisturbed armature and contained explosive, causing the detonation wave to increase in velocity and pressure. The detonation wave is thus continually accelerated by the generation of magnetic pressure preceeding the detonated explosive wave. | ||||||

| 192 | Explosive container | US628214 | 1975-11-03 | US4023494A | 1977-05-17 | Leslie W. Barton; Don H. Smith |
| A container capable of withstanding pressures having a longitudinal cord-receiving groove and a detonator-receiving groove formed as integral parts of the container. Radially projecting, substantially deformable, grooves are formed on the container at its upper and lower portions to retain a substantially non-deformable tubular sleeve positioned on the container, thereby covering the cord-receiving groove and the detonator-receiving groove. The threaded cap for the container has a projecting member which forms with the interior side walls of the cap, an annular slot for maintaining a resilient, deformable gasket. Upon threadedly engaging the cap with the threaded neck of the container the projecting member protrudes into and is adjacent the interior surface of the neck and the gasket cooperates with the edge portion of the neck to form the improved seal for the container. | ||||||
| 193 | Explosive booster casing | US483212 | 1974-06-26 | US3955504A | 1976-05-11 | Russell H. Romney |
| A casing or shell for explosive material to be used as a booster for detonating massive charges of blasting agents of low sensitivity is formed in two generally hemispherical half shell or casing members which are formed with sufficient precision that the two parts may lock together in telescoped relationship after filling, to form a liquid-tight joint. The two half shells are quite similar in size and shape but not identical, one bearing a flange having a hollow cylindrical inner surface into which a mating flange on the other is received; interlocking elements inside the outer flange and on the exterior surface of the inner flange hold the parts securely together by friction and without adhesive after full assembly. Each half shell includes a thin-walled tubular element which projects through and frictionally engages an opening in the other half shell as the two members are assembled, the parts being so arranged that a filling port and an air outlet port are provided when the parts are brought together but only partially closed to final position, these ports being closed completely when the two half shells are finally forced tightly together. The tubular elements are designed to receive and hold a primary detonator, such as an electric blasting cap or a length of detonating cord, and to hold such detonator securely in place after the booster is filled and sealed. | ||||||

| An intrinsically non-explosive liquid constituent of an explosive composition is contained within a can. The can is located inside of a plastic bottle. In the field an intrinsically non-explosive solid constituent of the explosive composition is poured from a separate container into a space in the bottle above the cam. The user presses down on the capped top of the bottle to move a downwardly projecting cutter carried by an upper portion of the bottle downwardly and through the top of the can. Following cutting the bottle is turned upside down and/or shaken to cause a mixing of the two constituents of the explosive composition. The resulting explosive is a liquid which can be poured from the bottle and then detonated by a conventional detonator, or detonated while still in the bottle.
