Abstract:

The patent is concerned with the problem of causing detonation of a mine which is sown from the air. Shortly after such a mine strikes the ground, small wires are shot out from the mine. Subsequently, a tension of two to three ounces in any one of the wires will result in detonation of the mine. The invention is concerned with providing an electrical system which can be contained within the mine and which is such that mere proximity to a tripwire is sufficient to explode the mine.
