Abstract From the Canadian patent
In a regenerative liquid propellant gun there is provided a passageway extending from a dispensing reservoir through the gun barrel to an opening into the bore of the gun at a location within the extent of that portion of the projectile to be fired which is in contact with the bore surface when the projectile is in its ready for firing position whereby the projectile acts as a valve to initially block flow of liquid propellant from the passageway into the bore and to subsequently permit such flow when the projectile moves down the barrel of the gun beyond said opening.

Why it's free to use
- Granted November 26, 1991. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended November 26, 2008.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
