It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractAn otherwise conventional shell is provided with a load consisting of a plurality of axially stacked disks. The disks separate during flight and each strikes the target with a substantial portion of the initial momentum imparted to the disks thereby contributing to the stopping power of the load. In alternative embodiments, individual disks are scored so that on impact, the disks shatter into many smaller fragments, each capable of penetration into the target to impart additional wound trauma to the target. Disks may be made of lead, ceramic, or other dense material. Alternatively, plastic or a relatively soft elastomeric material is used when a non lethal but debilitating load is appropriate such as in crowd control situations.Other References
