Abstract: A non-discarding sabot projectile consists of a projectile core; a lower core casing for insertion into a bore of a muzzleloader firearm; and an upper core cap fastly engaged with the lower core casing. Such an engagement between the upper core cap and the lower core casing defines a jacket so that, upon assembly of the lower core casing and upper core cap, the projectile core is encapsulated within the jacket.

Abstract: The invention comprises water desalination methods and a system for such, which includes treatment of water in cation and anion ion exchange columns, and regenerating the columns after treatment of the water to set them up again for a further treatment cycle, and also providing recoverable by-products during the regeneration of the ion exchange columns instead of waste.

Abstract: A process for providing water with a lowered salinity and which produces at least one recoverable waste stream containing a useful by-product, the process including treating raw water which includes an undesirably high concentration of cations, including Ca2+ and Na+, in a cation exchange stage which includes first and second cation exchangers. The first cation exchanger having a selectivity towards di-valent cations and the second cation exchanger being downstream of the first cation exchanger, to retain at least a portion of the cations of the raw water in or on the first and second cation exchangers, thereby providing upgraded water of a lowered salinity containing no or a low concentration of the cations of the raw water.
