摘要： Process for making a fragmentation warhead using hot isostatic pressing where tungsten spheres, powdered steel, and interlock features on a mandrel are consolidated in a matrix. Then in the finished part, the front fragmentation cap, rear and interior geometries are machined, resulting in a finished warhead with an enhanced performance fragmentation cap integrally bonded to it.

摘要： A gun barrel with piecewise helical barrel fluting comprises a single start non-stop feature of alternating and intersecting right hand and left hand helical segments. Piecewise helical barrel fluting combines the ease of manufacture of a single start fluting with the improved performance benefits of a multi-start approach, namely increased barrel stiffness and resulting performance with respect to firing accuracy and firing precision.

摘要： A wet chemistry method for preparing spherical celluloid beads by mixing a water-based suspension solution and a solvent based celluloid solution that is immiscible in the suspension solution. The two combined solutions create an “oil-in-water” type mixture where the dispersed phase consists of celluloid dissolved in solvent and co-solvent that is suspended in the continuous water phase. Agitation and removal of the solvent and co-solvent mixture produces spherical shaped celluloid beads.

摘要： A suppressed muzzle brake for automatic and semi-automatic weapons provides mitigation of recoil, muzzle climb and increased sound pressure levels while overcoming the deleterious effect of increased blast overpressure on the shooter. The suppressed muzzle brake includes a plurality of suppressor baffles for providing quick blowdown of the weapon and some muzzle brake function, a baffle brake which redirects the propellant gas in a direction and manner so as not to increase blast overpressure to unsuitable levels. In addition, openings in a can of the suppressed muzzle brake provide a compensator effect by inducing a downward force on the suppressed muzzle brake.

摘要： A sub-projectile carrier which uses aerodynamic drag to delay the release of a payload in a tailorable manner to control the spread of the payload over a desired range. A 40 mm shotgun style cartridge is shown for use for counter unmanned aerial systems, and for short range anti-personnel applications.

摘要： Methods, systems and devices for diffractive waveplate lens and mirror systems allowing electronically focusing light at different focal planes. The system can be incorporated into a variety of optical schemes for providing electrical control of transmission. In another embodiment, the system comprises diffractive waveplates of different functionality to provide a system for controlling not only focusing but other propagation properties of light including direction, phase profile, and intensity distribution.
