| 141 | 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 | US07849799B2 | 2010-12-14 | 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). | ||||||

The method further includes aborting the engagement of the target when the integrity check of the munition fails. | ||||||
| 146 | Fuze explosive ordnance disposal (EOD) circuit | US11284511 | 2005-11-22 | US07331290B1 | 2008-02-19 | Robert E. Keil |
| The present invention comprises an electronic Explosive Ordnance Disposal (EOD) circuit which is desirably used with fuzed explosive weapons, such as projectiles having a nominal mission time. After expiration of the mission time, if the explosive has not detonated, the inventive circuit controls the energy supplied to the fuze detonation circuit to a level that is less than a threshold level required by the fuze for detonation, thereby preventing subsequent detonation of the explosive. | ||||||
| 147 | SELF-DESTRUCT FUZE DELAY MECHANISM | US11383116 | 2006-05-12 | US20070261586A1 | 2007-11-15 | William Chamlee; Jerry Smith; Berry Flournoy |
| An exemplary self-destruct fuze delay for a submuntion includes an ampoule filled with an activation fluid, a spring-loaded pin to break the ampoule upon deployment of the munition, and a wick to collect and retain the activation liquid in contact with a spring loaded restraining link having an embedded firing pin. The activation liquid contacts the restraining link, preferably via the wick. The action of the activation liquid on the restraining link over time causes the link to fail at the predetermined location, allowing a severed portion with the embedded firing pin to move under force (e.g., spring, gas) and impact or initiate a secondary detonator. The secondary detonator is in close proximity to a primary detonator typically used to initiate a main charge of the submunition. Initiation of the secondary detonator destroys the primary detonator and, depending upon slide location, either sterilizes the submunition, or destroys the entire submunition. | ||||||

| 152 | System for controlling activation of remotely located device | US10318140 | 2002-12-13 | US20040112238A1 | 2004-06-17 | Edward B. Talbot |
| A system for controlling activation of a payload, particularly a high value, high consequence payload, such as a weapon of mass destruction, cannot be activated until it confirms that it has arrived at the correct destination. The system stores information that sufficiently identifies the location where the system should be activated or detonated. Sensors identify characteristics of the current location of the payload. A correlation is performed between the measured characteristics of the current location and the information stored that identifies the desired activation location. When the information sufficiently correlates, the system is allowed to activate. | ||||||
| 153 | Pyrotechnical impact detonator | US09178815 | 1998-10-26 | US06257145B1 | 2001-07-10 | Norbert Wardecki |
| A projectile includes a pyrotechnical detonation chain arranged to be ignited in response to a launching of the projectile. The chain includes two successive spaced-apart portions that are spaced apart to prevent ignition from being transferred therebetween. One of the portions is movable into contact with the other. A holder imposes a yieldable retaining force (e.g., friction, or shear pin) against the movable portion. That force can be overcome by momentum of the movable portion when the projectile strikes a target, whereupon the movable portion moves into contact with, and ignites, the other portion. | ||||||
| 154 | Air-safed underwater fuze system for launched munitions | US206939 | 1998-12-08 | US6131516A | 2000-10-17 | Matthew J. Sanford; Keith B. Lewis |
| An air-safed underwater fuze system is provided for munitions that are to launch-deployed and water-detonated. A housing defines a first bore contiguous with a second bore. Radial ports in the housing communicate with the first bore. A first piston is slidably mounted in the first bore and a second piston is slidably mounted in the second bore and positioned flush with the first bore. Piston control means are coupled between the munitions and first piston for positioning the first piston in a first position prior to launch in which the first piston seals off the radial ports while being spaced apart from the second piston to define a chamber. The piston control means moves the first piston at launch to a second position so that the chamber expands and the radial ports are in communication with the chamber. The piston control means further drives the first piston from its second position towards its first position at a specified time after launch. Once the first piston seals off the radial ports, the first piston pressurizes the water in the chamber. As a result, the second piston is driven along the second bore as actuating movement. A firing mechanism is provided in communication with the second bore and coupled to the munitions. The firing mechanism is responsive to the actuating movement of the second piston to generate detonation energy for the munitions. | ||||||
| 155 | Self neutralizing fuze | US204224 | 1998-12-03 | US6050195A | 2000-04-18 | Frank Diorio |
| A fuze self-neutralizing system is used for munitions having fuzes with sng-forced sliders (13) and stab detonators (19). The self-neutralizing components include an auxiliary battery (5), a auxiliary timing circuit (3) and a physical barrier (11) that prevents the firing pin (18) from contacting the stab detonator (19). Once the barrier (1) is in place, the munition can be handled with relative safety. | ||||||
| 156 | Device for arming and disarming a directional mine | US176867 | 1988-04-01 | US4856431A | 1989-08-15 | Jens Seidensticker |
| A directional mine for combatting armored vehicles includes a projectile having a propelling device and a warhead; a support structure positioning the projectile prior to launching the projectile therefrom and electric circuitry for serving the projectile. There is further provided an arming unit including a battery, and an igniter accommodated in a housing insertable into and removable from the support structure; an ejector for pushing the housing out of the support structure; a locking device for retaining the housing in the inserted position and for preventing the ejector from becoming effective; a timer for placing the locking device in a releasing state after a predetermined period for allowing the ejector to push the housing outwardly; and electrical contacts mounted in the support structure and on the housing. Respective contacts are in engagement with one another in the inserted position of the housing. | ||||||
| 157 | Self-sterilizing safe-arm device with arm/fire feature | US256445 | 1988-10-12 | US4854239A | 1989-08-08 | Peter H. Van Sloun |
| A safety apparatus to safe or to arm and fire a munition, utilizes a rotor containing an aligned adjacent firing pin and detonator in holes extending completely through the rotor perpendicular to the axis. A first explosively powered piston actuator, when fired, will unlock the rotor and enable a second explosively powered piston actuator, when fired, to rotate the rotor to align the detonator with an explosive charge and to cause a firing pin to fire the detonator. The detonator will fire a transfer lead which, in turn, will fire the main charge. As assembled, a third explosively powered piston actuator is aligned with the detonator and, when fired, will cause the detonator to explode and translate the rotor with part of the axis extending out of the munition where it is held in this position to indicate a safe condition. | ||||||
| 158 | Projectile impact fuze containing de-arming device | US939870 | 1986-12-09 | US4726294A | 1988-02-23 | Robert Apotheloz; Georg Leutwyler |
| It happens time and again that a fuze does not function and that the projectile remains in the field or the place where it landed as a dud. When such a dud is found the danger exists that it might explode upon the finder's touch or when moved or lifted. To prevent this danger the impact fuze in a dud should be able to de-arm itself in a non-explosive manner. This is achieved by positioning a dud insert or de-arming device between an explosive or firing train and a booster charge. This dud de-arming device contains an escapement device which after a predetermined delay time following impact of the projectile moves a rotor from its armed or live position into its de-armed or inert position. The dud de-arming device contains structure which, by virtue of the impact delay or deceleration, that is a delay in ignition of the booster charge upon the projectile hitting the target or ground, activates the escapement mechanism. | ||||||
| 159 | Safety means for an ordnance fuze | US24961 | 1987-03-12 | US4722277A | 1988-02-02 | Kenneth Sundvall; Stig Risberg |
| A safety means for an ordnance fuze. The arrangement includes an arming rotor (1) which is held in a safe position (A) by means of a half-shaft (6) which in the safe position of the rotor engages a first recess (7) located in the rotor. A clock mechanism (9) is provided so as to rotate the half-shaft (6) about its axis to a rotational position in which it no longer engages the rotor (1), thereby enabling the rotor to be rotated to its armed position. The rotor has provided therein a second recess (11) into which the half-shaft (6) is able to rotate should it be rotated at an excessively high speed, thereby returning the rotor to its safe position. | ||||||
| 160 | Safety fuse with automatic underwater self-disarming | US472003 | 1983-03-04 | US4487126A | 1984-12-11 | Hermann Schaper |
| A pressure-actuated fuse has a housing formed with an inner chamber and with a passage having an outer end opening to the exterior and an inner end opening into the chamber. A plug in the passage has a porosity sufficient to allow slow liquid flow through itself. An actuating element is exposed inwardly in the chamber and outwardly to the exterior and is displaceable in the housing by a pressure differential between the chamber and the exterior along an actuating axis between an outer position and an inner position. The chamber is substantially closed to the exterior except through the passage. A valve in the passage connected to the actuating element blocks liquid flow along the passage only when the actuating element is in its outer position. Thus, when the element moves out of its outer position liquid can flow through the plug and limitedly along the passage into the chamber. A spring braced between the housing and the actuating element urges it into its outer position so that only when the exterior pressure effective inwardly on the element is greater than the spring force can the element move into its inner position. A firing member is displaceable in the housing into firing position engaging and exploding a detonator therein. A link mechanism blocks the firing member from moving into the firing position except when the actuating element is in its inner position. Thus the interior of the device is cut off from the outside until the actuating member moves into its inner position, which normally only is when the device has been submerged fully. | ||||||
