  • Patent number: 11313655
    Abstract: A rear slip base plate for a round carrying a guidance and control unit payload, which round is launched from a rifled launch tube. To prevent the guidance and control unit payload from also being rapidly spun with the round, the slip base plate unit mechanically isolates the guidance and control unit payload from the round spin rate.

  • Patent number: 11312729
    Abstract: The present invention is directed to a process for continuous production of copper (I) nitrotetrazolate (DBX-1) by reacting aqueous copper salt with aqueous 5-nitrotetrazolate salt in the presence of a reducing agent. All the reactants are introduced into a continuous flow reactor system, which is composed of a temperature controlled tubular reactor and a mixer that allows for radial mixing. An optional stirred tank reactor may also be incorporated into the process to complete the reaction and allow for crystal growth.

  • Patent number: 11313656
    Abstract: A fin deployment mechanism for a projectile to release the fins laterally or radially. This pop-out type of mechanism therefore avoids need for a sabot for projectile launching purposes. By avoiding the weight and space usage of a sabot, there can be increased length and volume for the warhead and projectile, at the same weight burden.

  • Patent number: 11298689
    Abstract: Disclosed are various combinations of three different metal-oxide photocatalysts with three different bandgaps that can be used to harvest multiple wavelengths of incident solar radiation and to thus efficiently degrade recalcitrant contaminants. The photocatalysts are from the class of transition metal oxides and are non-toxic compounds based on earth-abundant materials. In some embodiments, particles of the photocatalysts are formed to be greater in diameter than about 0.1 ?m in order to make them easier to filter out after treating the contaminant. In some embodiments, the metal-oxide photocatalysts are zinc oxide which is ultraviolet active, hematite which is active in the visible spectrum, and copper oxide which is active in the near infrared spectrum. Various combinations in various embodiments achieve measured contaminant degradation rates greater than the sum of the degradation rates of the individual photocatalysts that make up the combination.

  • Patent number: 11293724
    Abstract: Enclosed structures, such as guard towers, are provided which are designed to be easily transportable, constructed easily onsite and erected in a manner which produces an exceptionally blast resistant structure that is also advantageously designed for positioning within a perimeter wall. In particular, in some embodiments, the guard towers have a pentagon shape and are comprised of a plurality of composite panels. Each panel is able to be constructed onsite. The panels typically have a rectangular shape with at least one half of the panel constructed as a solid composite of concrete and metal. Once the panels are constructed, the panels are erected and arranged in a pentagon shape. The panels are bolted together with the use of vertical face connections. These connections provide better structural integrity, retained over time, particularly after subjection to a blast. In addition, the pentagon shape provides improved safety when positioned along a perimeter wall.

  • Patent number: 11287229
    Abstract: The present invention is directed to a process for making combustible foam celluloid munition parts having high aspect ratios, different densities or having an insert embedded into the foam celluloid munition part. The process for making such foam celluloid munition part requires pre-soaking dry particles of celluloid, placing the celluloid particles into a munition part mold, exposing the celluloid particles to high heat and pressure until the celluloid particles expand and fuse into the shape of the mold. Varying the density or the size of the celluloid particles used in the process produces munition parts having different densities. In addition, the placement of inserts into the particles prior to exposure to high heat and pressure produces munition parts having inserts that are useful for identification and tracking of such parts.

  • Patent number: 11290181
    Abstract: Measurement of entangled photon quantum wavefunction properties is vital for studying the fundamentals of entanglement and for future applications in quantum communications, quantum metrology, quantum sensing and imaging. Despite its importance, measuring the wavefunction is difficult, particularly in pulsed and other systems with system features and wavefunctions changing in space and time. This invention uses ghost imaging techniques to directly measure the entangled photon wavefunction of pulsed origin temporal and polarization entangled photons. The invention may be used to improve wavefunction quality after propagation through turbulent or scattering media.

  • Patent number: 11287237
    Abstract: In a projectile launch environment, a fuzing safety device independently generates its own voltage upon setback which then is then used to arm the projectile. The arming is done independently of any on board battery rise time, and setback scenarios are detected free of false impacts such as dropping or jostling. The fuzing safety device includes a piezoelectric sensor for detecting motion in the projectile.

  • Patent number: 11280588
    Abstract: Ready armor modular protective systems that can be rapidly deployed in an urban environment. Exemplary armor systems include a container, and a wall assembly that fits inside of the container when in a collapsed configuration. The wall assembly includes a first end section, a second end section, a constraint mechanism, and first and second locking mechanisms. The first end section has a first space frame unit, and the second end section has second and third space frame units. A locking mechanism prevent relative vertical displacement from occurring between adjacent second and third space frame units. The constraint mechanism keeps the first and third space frame units at a fixed distance from one another. The constraint mechanism, when coupled with the first and third space frame units, keeps the locking mechanism from being removed from the second end section.

  • Patent number: 11273574
    Abstract: A scalable three dimensional printing apparatus capable of movement along three axes includes a tractor assembly movable along a selectively extendable rail component. Wheels in the tractor assembly surround part of the rail component to enable movement of a gantry bridge in a longitudinal direction along the rails. A movable printing trolley moves horizontally along a gantry bridge and has a printing column which can move vertically. Because the gantry bridge, trolley, and printing column move orthogonally to each other, users may print in three dimensions. Selective extension of the rails allows a user to alter lengthwise printing scale.
