Abstract: A system for remote washing, such as for truck washing, including a mat that can wick liquid run-off, a water suction system that includes multiple modules for resting on the mat, and a vacuum.

Abstract: An extractable, reusable, two piece, plactic cartridge, housing a compression nozzle, chamber and pusher disc, having at one end of cartridge an opening to receive a compressionable, halved, hollow point projectile sleeve which contains a soft, compressionable, liquid marking projectile. A solid pusher disc located inside the cartridge, is secured to the interior wall of the cartridge by an elastic tube. The disc having a flat forward side which makes complete surface area contact with projectile sleeve. The aft side of disc being concaved is seated forward of a thrust port, smaller in diameter than the concaved section of disc. The thrust port is the smaller opening of two openings of a conical shaped compression nozzle, which has four equally spaced channels extending from the thrust port longitudinal to the larger opening which joins a circumferencially identical, partially closed end propellant chamber. The chamber, channels and compression nozzle contain the propellant charge.
