Abstract: A method of forming a gun ammunition projectile 52 including a leading end defined by an ogive 53 including the steps of admixing a quantity of a first powdered metal having a first melting point and a first density, with a quantity of a second powdered metal having a second, and lower, melting point and a second, and lesser, density, pressing a quantity of the admixed metal powders into a self-supporting compact having at least an outboard end disposing the compact in a cup-shaped jacket, heating the compact in the jacket, in a vertical attitude, to a temperature of at least the melting point of the second metal but less than the melting point of the first metal, for a time sufficient to result in a liquefied portion of the second metal migrating to and accumulating at the one outboard end of the compact.

Abstract: A bullet for law enforcement and personal defense use capable of meeting current FBI and IWBA standards and comprised of a jacket of malleable metal having a cylindrical side wall, tapered nose portion, an open forward end, and a plurality of deep longitudinally extending scores formed in the nose portion and defining petals therebetween which extend rearwardly from its mouth, and a malleable core mounted within the jacket and having a plurality of separate segments extending forwardly from its cylindrical base into the nose portion of the jacket and terminating adjacent said open jacket end in a shallow hollowed point, the bullet being capable of piercing substantial barrier materials before entering its target and thereafter expanding radially to about 1.5-2.0 times its diameter, while traveling 9-16 inches within its target.

Abstract: A method of monitoring reactivity changes in a nuclear reaction when the nuclear reaction is subcritical. The method controls the parameter of the nuclear reaction that affects reactivity of the reaction to slightly alter the reactivity while monitoring an output of a source range detector. The Inverse Count Rate Ratio from the output of the detector is determined periodically during a transient portion of the output. A correction factor is applied to the Inverse Count Rate Ratio data and the data is plotted as a function of time. The correction factor linearizes the Inverse Count Rate Ratio data so that the curve can be predictably extrapolated.

Abstract: An automatic choke system for automatically adjusting the amount of choke applied to a series of shots discharged from shotgun. The automatic choke system includes a tube assembly with a plurality of longitudinal slits within the distal end thereof, a collar unit attached about the tube assembly, and a swedge assembly slidably positioned between the tube assembly and the collar unit. A latch unit attached to the collar unit selectively allows the swedge assembly to move forwardly one position after each shot fired. The latch unit is operated by gas flow from the interior of the barrel of the shotgun during a shot.

Abstract: A method and vehicle occupant restraint system for a motor vehicle, in which the webbing movement of a seat belt wound on a belt reel 1 caused by the body of the belted-in vehicle occupant is scanned and corresponding measurement data are fed to an evaluating device 3, wherein measurement data relating to the rotating movement of a rotor 2, in particular the electric motor rotor, which serves in tightening the seat belt webbing, may additionally be fed to this evaluating device 3.
