Embodiment Construction

[0004] A device for the rapid and controlled destruction of a large number of valuable documents is described. The device comprises a primary incineration charge, a propellant charge and an extinguisher charge. The two former are electrically triggered by an external signal, and the latter is triggered once a precise portion of the propellant charge has been consumed. In addition to the charges, the device includes electrically triggered igniters and initiators, a fully-sealed long lifetime battery, fully-sealed trigger reed switches, and associated circuits and wiring.

[0005] The primary destruction mechanism is by high-temperature incineration, caused by well known, localized, Metal / Metal-Oxide exothermic redox reaction. The invention utilizes a single composite pyrotechnic charge and housing to destroy a specific portion of every document in a stack. Since the design is linearly scalable to arbitrary limits, only one charge is required for any number of stacked documents. This is...

Abstract

A pyrotechnic device for destruction of valuable documents in which a primary incineration charge and a propellant charge are electrically triggered by an external signal, and an extinguisher charge is triggered when a precise portion of the propellant charge is consumed.

Description

FIELD OF THE INVENTION [0001] This invention relates a device for destruction of valuable documents and more particularly to a pyrotechnic device for destruction of valuable documents which is capable to destroy efficiently the documents contained therein, independently of the amount and / or thickness. BACKGROUND AND PRIOR ART [0002] Prior pyrotechnic based techniques for the rapid and reliable destruction of valuable documents are severely limited in the thickness of the document stack which they can reliably destroy. Protection systems based on prior art which are intended to destroy large quantities of notes therefore require multiple pyrotechnic charges and their associated multiplicity of ignition systems and circuits. They also require that large stacks of documents be split into many smaller stacks in order not- to exceed the maximum thickness constraint. [0003] Documents to be potentially destroyed are more conveniently arranged in large piles or stacks however, whether for s...
