Abstract: A three component bullet with an improved core retention feature and a method of manufacturing the bullet includes a cylindrical jacket having an open end and a closed end containing a malleable metal core which is forced into a forming die having a bottleneck shaped interior, wherein the outside diameter of the open-ended forward portion of the jacket is smaller than the outside diameter of its closed rearward portion. The open end of the pre-form may be dropped through or forced through a malleable non-rigid locking band. A relatively tight-fitting punch enters the open end of the pre-form, to radially swell the core and subsequently portions of the jacket fore and aft of the non-rigid locking band, thereby securing the non-rigid locking band in place. An inwardly-extending annular band of jacket material embeds itself into the core material to lock the core inside the jacket.

Abstract: A method and apparatus for intentionally slowing the speed at which detachable ammunition magazines can be interchanged in a firearm receiver. A magazine catch assembly includes a latch adapted to engage a recess of a standard magazine in the magazine well. A hand-activated crank interacts with threads of a push-rod portion of the latch so that manual rotation of the hand crank in one direction (e.g., counter-clockwise) displaces the latch after a sufficient number of turns. Reverse rotation of the hand crank returns the latch to its engaged condition ready to automatically re-engage the next magazine inserted into the firearm receiver. Alternatively, viscoelastic foam or other mechanical time-delay feature can be used instead of screw threads to introduce a mechanically transmitted dwell period before the latch is actuated.

Abstract: A gun safety device on a gun automatically prevents the gun from firing when it is inside a registered area, which includes: a positioning device for determining the geographic position of a gun; a data processing device for identifying whether the gun is located within a registered area by comparing the gun's position with the stored geographic positions of the registered areas, and for generating a disable signal when the gun is identified to be inside a registered area; and a safety seizer operable to prevent the gun from discharging in response to receiving the disable signal from the data processing device. The automatic gun safety device may further include a communication device for communications with external networks. Optionally, the data processing device sends the gun's location to a monitoring center. The practice of this invention will ensure the community safety meanwhile defend the constitutional right of gun ownership.

Abstract: The problem of penetrating through nets and other objects is solved by cutting the object using concentric cutters in which a rotatable cutter having floating teeth rotates concentrically about a stationary cutter having fixed teeth. The object is cut by a severing action caused by the floating teeth of the rotatable cutter sliding against the fixed teeth of the stationary cutter. Embodiments of the invention include a UUV system for penetrating through fishing nets and other objects, concentric cutting assemblies for use in the UUV system and other systems, and a method for penetrating through fishing nets and other objects. A UUV system in accordance with an embodiment of the invention has a concentric cutting assembly at the forward end and a propulsor at the aft end. The concentric cutting assembly integrates seamlessly within the UUV housing and is deployed from the forward end of the UUV, enabling the UUV to quickly and efficiently penetrate through objects blocking its path.
