| 30 | SYSTEMS AND METHODS FOR CHEMICAL AND/OR MECHANICAL REMEDIATION OF NITRO COMPOUNDS AND NITRATE ESTERS | US12822730 | 2010-06-24 | US20110041718A1 | 2011-02-24 | Carl Hermanus Lubbe; Delana Harris; Jose Manuel Botija González; Fernando María Beitia Gómez De Segura |
| Systems and methods for chemoremediation or mechanical destruction of undetonated explosive materials. An explosive apparatus contains an explosive material in close proximity to a chemical reagent selected for its chemoremediative properties. A barrier is interposed between the explosive material and the chemical reagent to delay the chemoremediation of the explosive material.Alternatively a water expandable material may be incorporated into the explosive material, whereby upon exposure to moisture the water absorbing material will expand sufficiently to fragment the explosive material into initiation insensitive particles. Initiation insensitivity is achieved by incorporation of water, which acts as a desensitizing agent as well as fragmenting the explosive material into particles sufficiently small that they are below the critical diameter for explosive initiation.The present invention also relates to self-degradable, shaped explosive formulations, comprising an explosive material and a water expandable material. | ||||||

| 32 | STACKED ORDNANCE | US11789510 | 2007-04-24 | US20100011953A1 | 2010-01-21 | Steve Hines |
| A stacked ordnance device provides a disposable and non reusable projectile weapon for passive area defense or denial. A stacked ordnance device has multiple projectiles and charges positioned sequentially in a barrel. A sensing module triggers a control module to enter a firing sequence. The firing sequence is the order and timing by which an electronic ignition system ignites firing charges and thereby shoots the projectiles. A mount positions the stacked ordnance device. The controller can also trigger a disabler that renders the stacked ordnance device unfit for subsequent use. | ||||||

| 34 | FUZE EXPLOSIVE ORDNANCE DISPOSAL (EOD) CIRCUIT | US11284511 | 2005-11-22 | US20080035004A1 | 2008-02-14 | Robert Keil |

| 36 | Supplement to mines by which the time period is limited within which the activation of mines after their placing is possible | US10595347 | 2004-10-15 | US20070101890A1 | 2007-05-10 | Boris Pervan |
| The invention consists of initial part (2B), which at the lower side is made in pyramid form and is part of mine activating mechanism (1). At its screwing into mine body (3), ampoule (D2) containing the aggressive matter is broken by the sharp point, the matter spills and comes to initial part (2B) that gets immersed in it. The aggressive matter slowly corrodes the walls of initial part (2B) and, when it corrodes them through, it mixes with the initial explosive placed inside initial part (2B), soaks it and neutralizes it, in such a way the initial explosive looses its explosive properties, and the mine cannot be activated any more. Cylindrical housing (D) serves for placing ampoule (D2) and retaining the aggressive liquid after breaking ampoule (D2). | ||||||

When an integrity threshold is not met, engagement of the munition with a predetermined target is aborted. Also presented is a methodology for gating the engagement of the munition with the target. The methodology includes performing an integrity check of the munition after it is deployed. The method further includes aborting the engagement of the target when the integrity check of the munition fails. | ||||||
| 39 | Projectile launch detection system utilizing a continuous wave radio frequency signal to confirm muzzle exit | US10709448 | 2004-05-06 | US06967614B1 | 2005-11-22 | Ronald G. Wardell; John I. Nickel; Dennis W. Ward |
| A projectile launch detection system utilizes a continuous wave radio frequency signal (CW/RF) to confirm muzzle exit. The projectile launch detection system can be used in smoothbore, fin-stabilized, non-air breathing projectiles. The gun tube appears as a waveguide to the projectile launch detection system during projectile launch. The projectile launch detection system transmits a CW/RF signal down the gun tube during launch of the projectile. A portion of the CW/RF signal is reflected back by an impedance mismatch at the boundary between the muzzle of the gun tube and free space. Upon exit by the projectile from the gun tube, an exit signature is detected that is defined by the impedance of the gun tube and by a ratio of the diameter of the gun tube to the frequency of the CW/RF signal. The projectile launch detection system processes the exit signature to detect a muzzle launch of the projectile from a specific gun tube. | ||||||
| 40 | Electronic self-destruct device | US10258235 | 2001-03-22 | US06865989B2 | 2005-03-15 | Bertram Kölbli |
| A device provides for time-controlled self-destruction of a projectile by a batteryless, electronic self-destruct device. Several capacitors charged by a piezo element or a surge generator during firing are used in the flight phase for operational purposes. At least two of the capacitors are connected to the input of a comparator, so that the influence of a constantly modifiable operational voltage and the influence of a discharge of modifiable voltage levels by the piezo element or surge generator does not affect the time function. | ||||||
