  • Patent number: 11150060
    Abstract: A base body for a metal-sealing material-feedthrough subject to high pressures in an igniter for an airbag or a belt tensioning device. The base body for the metal-sealing material feedthrough is an element formed by a process of cold forming and having a ring-shape or a plate-like shape. The element includes a feedthrough opening extending from a front side of the element towards a rear side of the element. There is a metallurgic section in the element of the base body with structure-lines or flow-lines that are bent due to a reshaping process of the process of cold-forming.

  • Patent number: 11150064
    Abstract: A radar-absorbing material projectile system including a projectile with an outer layer of radar-absorbing material (RAM). A carrier or armature is disposed around the projectile, protecting the layer of RAM during the firing sequence. In some embodiments the carrier is a discarding carrier which falls away after firing, rendering the projectile low-observable with regard to radar detection due to the layer of RAM.

  • Patent number: 11150068
    Abstract: A stemming plug (60) for stemming a blast hole in a mine is disclosed. The plug has first and second wedge-shaped members (62?, 62) manufactured from a suitable plastics material. The first wedge-shaped member (62?) has a first sloping face received in sliding relationship with a matching face of the second wedge-shaped member (62) wherein, in use, when the first wedge-shaped member (62?) is positioned nearest to an explosive material in the blast hole it has a larger surface area facing the explosive material than the second wedge-shaped member (62). In use, when a Shockwave from initiation of the explosive material in the blast hole encounters the first wedge-shaped member (62?) it acts as a piston, sliding on the second wedge-shaped member (62) so that both wedge-shaped members exert diametrically opposed forces against the wall of the blast hole to lock the plug (60) in place. The two wedge-shaped members (62?, 62) may be substantially identical, thus significantly simplifying the manufacturing process.

  • Patent number: 11073368
    Abstract: The present invention comprises a novel device, a ceramic cap that is firmly attached in a manner that prevents relative rotation axial movement or separation between the modified tip of an existing bullet and said cap to allow the modified bullet to shatter the glass of an automotive or truck windshield on contact, thus allowing the bullet to pass through the glass with a reduction of deflection incurred by non-modified bullets while producing larger bullet holes and areas of glass disruption than non-modified rounds and increasing the quantity and size of injury inflicting shrapnel.

  • Patent number: 11067376
    Abstract: Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

  • Patent number: 11053782
    Abstract: According to some embodiments, a shaped charge inlay includes an upper edge that extends inward and horizontal to an edge of a shaped charge casing associated with a shaped charge. The shaped charge includes an existing liner and the shaped charge inlay further includes a body that extends inward toward an apex of the existing liner. The shaped charge inlay may be disposed above the existing liner in the shaped charge, to disrupt collapse of the existing liner upon detonation of the shaped charge and thereby change the geometry of a perforating jet and resulting perforation created by the shaped charge. The perforation holes formed by shaped charges having the shaped charge inlay may have geometries that include constant open areas to flow in the target when the perforating gun is centralized or decentralized in a wellbore casing.

  • Patent number: 11047666
    Abstract: Embodiments employ venting features and damping components both inside and concentric to a fuzewell to improve munition fuze survivability. Damping components are selected based on their densities and stiffness properties. A shock damping liner with longitudinal grooves is affixed to an inner surface of the fuzewell and envelops the fuze. At least one shock damping collar constrains and attenuates shock experienced by the fuze. A shock damping ring is concentric about the outer surface of the fuzewell and attenuates shock between the outermost munition system layer (the casing) and the fuzewell. Longitudinal vents in the fuzewell wall and radial apertures oriented transverse to the longitudinal vents are used for off-gassing. The venting and component orientation combination provides increased damping, resulting in impedance mismatches across multiple interface surfaces in the munition, which reduces shock vibrational pressures and stresses transferred to the fuze.
