  • Solid state laser and material
    Patent number: 4301426
    Abstract: Broadly tunable, c.w. laser action in the ir(infrared) spectral region is obtained from (F.sub.2.sup.+).sub.A color centers in an alkali halide crystal having F.sub.A, F.sub.B, F.sub.A ', F.sub.B ' (F.sub.2).sub.A and (F.sub.2.sup.+).sub.A color centers in a dynamic equilibrium. The laser material is prepared by additively coloring an alkali halide crystal, exposing the colored crystal to light in the high-energy edge (i.e., between 450-300 nm) of the F-center absortion range at a temperature from about 253K to about 300K, cooling the crystal to a temperature not greater than 100K, and re-exposing the crystal to the same light to create a dynamic equilibrium state in which (F.sub.2.sup.+).sub.A centers are present.

  • Rotary locking mechanism
    Patent number: 4296689
    Abstract: A mechanism for immobilizing an arming shaft to preclude axial movement of he shaft until its release is desired, comprising a base and rotor mounted thereon. The rotor holds hardened metal balls in engagement with a circumferential groove on the shaft to lock the shaft in position. The base, rotor and shaft are held in locked position by an arming wire. Compression springs acting between the base and rotor cause relative rotation thereof, when the arming wire is removed, to an unlocked position where the balls can be forced into apertures in the base and release the shaft for axial movement.

  • Module to prevent sympathetic detonations in munitions
    Patent number: 4286708
    Abstract: The sympathetic or chain reaction detonation of stacked munitions is preved by confining any random explosion essentially to a single explosive unit or container. Frangible inhibitor plates are located between adjacent munitions, such as artillery shells, so as to isolate the adjacent explosive units from a residual shock wave or case fragment that would otherwise trigger sympathetic detonation. The inhibitor plates may be constructed as part of a container in which an artillery shell may be stored, or the plates may be separately inserted between any adjacent warhead in any conventional storage pallet or transporting configuration. The plates are designed to absorb only that amount of explosive energy required to prevent sympathetic detonation, without requiring that the explosive forces be redirected away from adjacent shells, thus reducing the problem of redirected blast.
