A pursuit vehicle carries a projectile housed within a launcher mounted on its front end. The projectile is able to be directed at high speed from the launcher toward a tire of a pursued vehicle. A tether line is coiled about a tether reel within the chase vehicle and is fixed to the projectile. The projectile has folded barbs that extend once the projectile has entered the tire and which keeps the projectile from flying out of the tire due to centripetal force. Being penetrated, the tire quickly looses pressure and deflates while the tether line wraps itself around the wheel's axle and brakes which can cause the wheel to stop spinning.

A cyclonic chamber for use in air filtration devices. The chamber includes an apex opposite a base with sidewalls extending therebetween. The cyclonic chamber is preferably parabolic in cross-section or tubular with a hemi-spherical cap. The base contains an outflow passage and a conical filter extending therefrom. An inflow passage is provided proximate the apex. The inflow and outflow passages are parallel but not aligned. The chamber interior is smooth. The smooth interior and offset relationship of the inflow and outflow passages causes air to take a cyclonic path between the inflow passage and the filter. Debris in the airstream is pushed outward—away from the filter—by centripetal force. Eddies form proximate the base. Debris escapes the airstream there, where it either remains or, depending upon the chamber's orientation relative to gravity, falls back into the airflow where it is again directed away from the filter.

The present invention relates to a rotating fluidized bed apparatus for powder particle. A gas circulation path is formed at the periphery of the treatment chamber 2 via the circumferential faceplate 202, 212, and the circumferential faceplate is adapted to rotate around an axis.
