Title: Explosive assembly and method

Abstract

An explosive assembly includes a first explosive unit having a first longitudinal end portion having a first mechanical coupling feature, a second explosive unit having a second longitudinal end portion having a second mechanical coupling feature, and a tubular connector having a first end portion mechanically coupled to the first mechanical coupling feature and a second end portion mechanically coupled to the second mechanical coupling feature, such that the first explosive unit, the connector, and the second explosive unit are connected together end-to-end along a common longitudinal axis. Each explosive unit can contain a high explosive material and a detonator, and the connector can comprise a detonation control module electrically coupled to the detonators and configured to detonate the explosive units.

Method for enhancing stability of high explosives, for purposes of transport or storage, and the stabilized high explosives

Patent Nutt, Gerald L [Menlo Park, CA]

The stability of porous solid high explosives, for purposes of transport or storage, is enhanced by reducing the sensitivity to shock initiation of a reaction that leads to detonation. The pores of the explosive down to a certain size are filled under pressure with a stable, low melt temperature material in liquid form, and the combined material is cooled so the pore filling material solidifies. The stability can be increased to progressively higher levels by filling smaller pores. The pore filling material can be removed, at least partially, by reheating above its melt temperature and drained off so that themore » « less

Wiring assembly and method of forming a channel in a wiring assembly for receiving conductor and providing separate regions of conductor contact with the channel

Patent Stelzer, Gerald; Meinke, Rainer; Senti, Mark

A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method provides a first insulative layer tubular in shape and including a surface along which a conductor segment may be positioned. A channel formed in the surface of the insulative layer defines a first conductor path and includes a surface of first contour in cross section along a first plane transverse to the conductor path. A segment of conductor having a surface ofmore » « less
