Explosive logic network

An explosive logic network comprising:

• a first explosive path extending from a first end to an opposite second end;
• second and third explosive paths which are disposed on opposite sides of the first path and which intersect the first path at a first intersection, the second and third paths extending from respective outer ends to the first intersection, the second and third paths intersecting the first path at respective acute angles such that a detonation propagating along either the second or third paths into the first intersection is allowed to propagate along the first path toward the second end of the first path but is not allowed to propagate along the first path towards the first end of the first path;
• and
• fourth and fifth explosive paths which are disposed on opposite sides of the first path and which intersect the first path at a second intersection intermediate the first intersection and the second end of the first path such that a detonation propagating along the first path towards the second end of the first path is also allowed to propagate along both the fourth and fifth path away from the second intersection, the fourth path being disposed on the same side of the first path as the second path and the fifth path being disposed on the same side of the first path as the third path, the fourth path intersecting the second path at a third intersection such that a detonation propagating along the fourth path away from the second intersection is allowed to propagate along the second path towards the outer end of the second path, and the fifth path intersecting the third path at a fourth intersection such that a detonation propagating along the fifth path away from the second intersection is allowed to propagate along the third path towards the outer end of the third path, wherein the portion of the second path extending between the third intersection and a first intersection is shorter than the explosive path between the third intersection and the first intersection which passes through the second intersection, and the portion of the third path extending between the fourth intersection and the first intersection is shorter than the explosive path between the fourth intersection and the first intersection which passes through the second intersection.

An explosive logic network, comprising;

• a first explosive path extending from a first end to an opposite second end;
• second and third explosive paths which are disposed on opposite sides of the first path and which intersect the first path at a first intersection, the second and third paths extending from respective outer ends to the first intersection, the second and third paths intersecting the first path at respective acute angles such that a detonation propagating along either the second path or the third path into the first intersection is allowed to propagate along the first path towards the second end of the first path but is not allowed to propagate along the first path towards the first end of the first path;
• fourth and fifth explosive paths which are disposed on opposite sides of the first path and which intersect the first path at a second intersection intermediate the first intersection and the second end of the first path such that a detonation propagating along the first path from the second end of the first path toward the first end of the first path is also allowed to propagate along both the fourth and fifth paths away from the second intersection, the fourth path being disposed on the same side of the first path as the second path and the fifth path being disposed on the same side of the first path as the third path, the fourth path intersecting the second path at a third intersection intermediate the first intersection and the outer end of the second path and the fifth path intersecting the third path at a fourth intersection intermediate the first intersection and the outer end of the third path, the fourth path intersecting the second path at an acute angle such that a detonation propagating along the fourth path into the third intersection is allowed to propagate along the second path towards the first intersection but is not allowed to propagate along the second path towards the outer end of the second path, the fifth path intersecting the third path at an acute angle such that a detonation propagating along the fifth path into the fourth intersection is allowed to propagate along the third path toward the first intersection but is not allowed to propagate along the third path toward the outer end of the third path, the fourth path being the shortest explosive path between the second intersection and the third intersection, and the fifth path being the shortest explosive path between the second intersection and the fourth intersection.

An explosive panel including a plurality of interconnected explosive tile assemblies, each tile assembly comprising:

• a tile of explosive material;
• a peripheral path of explosive material extending about the tile;
• a plurality of connecting links of explosive material, each extending from a inner end across the peripheral path at a first intersection to an outer end which is connected to a link outer end of at least one adjacent tile assembly, the number of links being sufficient to connect the tile assembly to every adjacent tile assembly, portions of the peripheral path on opposite sides of each link being directed inwardly of the tile as the peripheral path approaches the first intersection such that the link and the portions of the peripheral path on opposite sides of the link intersect at respective acute angles between the peripheral path portions and an outer portion of the link extending outwardly from the first intersection, such that a detonation propagating along the peripheral path in either direction towards the connecting link will propagate inwardly along the link to open the outer portion of the link;
• a like plurality of first explosive logic means, associated respectively with the connecting links, for propagating an incoming detonation to the tile assembly along the associated link from an adjacent tile assembly in opposite directions away from the associated link along the peripheral path;
• and
• a like plurality of explosive delay means, connected respectively between the inner ends of the connecting links and the tile, for delaying an incoming detonation along any link so that the detonation will be propagated about the peripheral path and all other connecting links of the tile assembly will be cut before the detonation can be propagated through the tile to any other of the connecting links.
