International Classification:

B64D 104

US Classification:

89 113, 86 50, 102364

Abstract:

A projectile for the destruction of unexploded ordnance comprising a dart shell having a core region which contains a reactive composition comprised of a reactive metal and an oxidizer. The reactive metal is selected from the group consisting of titanium, aluminum, magnesium, lithium, beryllium, zirconium, thorium, uranium, hafnium, alloys thereof, hydrides thereof, and combinations thereof. The oxidizer is selected from the group consisting of lithium perchlorate, magnesium perchlorate, ammonium perchlorate, potassium perchlorate, chlorates, peroxides, and combinations thereof. In an alternative embodiment, the reactive composition is located on the outside of a center penetrating rod. Also included is a disposable apparatus for delivering a projectile to destroy unexploded ordnance. The apparatus is comprised of a block having a top and a bottom, the block comprised of a material selected from the group consisting of wood and polymeric resin. Within the block is a barrel disposed on the bottom of the block, the barrel comprised of a material selected from the group consisting of fiberglass and polymeric resin.

International Classification:

H05H 3/02

US Classification:

250251

Abstract:

The device for producing laser-cooled atoms comprises a two dimensional trap or a three-dimensional trap, or a combination of two- and three-dimensional traps. The two-dimensional trap comprises: three or more permanent magnets arranged around a perimeter of a loop, wherein a plane of the loop is perpendicular to a free axis of the two-dimensional atom trap, and the three or more permanent magnets bracket an internal volume of the two-dimensional atom trap; and one or more laser beam input ports enabling access for one or more laser beams to the internal volume of the two-dimensional atom trap.
