Abstract
Barrel assemblies (1) each include a plurality of projectiles (11) arranged in-line within barrel (12) and associated with discrete selectively ignitable propellant charges (13) for propelling projectiles (11) through the muzzle of barrel (12). Projectiles (11) are arranged with one another and barrel (12) so as to prevent rearward travel of an ignited propellant charge to the trailing propellant charge. The matter or objects contained within holding body (17) may include explosive charges for scismic exploration, fire retardants, fire extinguishing means, pyrotechnics, herbicide, insecticide, fertilizer or seeds. Methods of delivering loaded projectiles (11) for civilian purposes are claimed.
Claims18
A method of seismic exploration of a remote land or marine site, said method including the steps of:
- providing a barrel assembly comprising a barrel having a plurality of projectiles arranged in-line within the barrel in sealing engagement with the barrel and which projectiles are associated with discrete selectively ignitable propellant charges for propelling the projectiles sequentially through the muzzle of the barrel, wherein said sealing engagement prevents rearward travel of an ignited propellant charge to a trailing propellant charge, which barrel assembly is capable of firing a plurality of seismic signal instigating projectiles;
- and
- firing said plurality of seismic signal instigating projectiles from said barrel assembly to the ground or water at a selected rate and/or directions to propagate a desired seismic signal.
A method of seismic exploration of a remote land or marine site, said method including the steps of:
- providing a cluster of barrel assemblies, each barrel assembly of the cluster comprising a barrel having a plurality of projectiles arranged in-line within the barrel in sealing engagement with the barrel and which projectiles are associated with discrete selectively ignitable propellant charges for propelling the projectiles sequentially through the muzzle of the barrel, wherein said sealing engagement prevents rearward travel of an ignited propellant charge to a trailing propellant charge, which barrel assemblies are each capable of firing a plurality of seismic signal instigating projectiles;
- and
- firing individual ones of said plurality of seismic signal instigating projectiles from selected ones of said barrel assemblies to the ground or water at a selected rate and/or directions to propagate a desired seismic signal.
