  • Projectile dispensing system and use
    Patent number: 9339855
    Abstract: In one embodiment the present invention is a system comprising a feeder to feed projectiles. There is a conveyor for metering the projectiles, and that conveyor is in communication with the feeder. A pipe is in communication with the conveyor, for impelling projectiles through the pipe. In another it is use of a barrel internally lined with a helical blade for unconfined metering of projectiles to clean a gas pressurized pipe.
