Abstract: A cartridge case for a telescoped ammunition round has a generally tubular case wall and an axially extending elongate score line in said wall to provide pressure relief during firing of the round. The elongate score line has a radial depth less than the radial thickness of the wall.

Abstract: An ammunition round has a plastic molded driving band on a projectile. The driving band is mechanically attached to the projectile by opposing curved hooks bent toward one another and defining a restraining area therebetween. The seating area for the driving band has a plurality of pairs of such hooks circumferentially and longitudinally displaced from one another.

Abstract: A discarding sabot projectile comprises:a subcaliber projectile;a discarding sabot means for providing a full caliber carrier for the projectile;a discarding sabot base abutting a rearwardly facing surface of the aft end of the projectile, which base is free of direct positive coupling to the projectile;sabot/projectile coupling means for direct connection of the discarding sabot means to the projectile to prevent axially forward displacement of the projectile relative the sabot; andsabot/base coupling means for direct and positive connection of the discarding sabot means to the sabot base, locking the projectile into position within the cavity defined by the discarding sabot means and sabot base.

Abstract: A method for enhancing the development of mycorrhizae in the root system of a plant. A quantity of a nutrient mixture is applied to the outside surfaces of the foliage of a plant rooted in a growth medium containing propagules of a fungus capable of mycorrhizal infection of the roots, the nutrient mixture containing a source of nitrogen and a source of at least one other element selected from among potassium, phosphorus, zinc, magnesium, boron, manganese, molybdenum, copper, and iron, in an aqueous vehicle. Such application is repeated at intervals over a period of time during which the supply of nutrients by fertilization is provided predominantly through such foliar application.

Abstract: An armor-piercing projectile comprises a penetrator core carried within a scarding segmented sabot equipped with a plastic spinner band. While the core-sabot assembly is traveling through a rifled gun barrel the plastic band interengages with the rifling to impart spin to the assembly. The rifling severs the spinner band so that when the assembly exits from the barrel the sabot segments are centrifugally slung off of the penetrator core. The core continues its flight toward the target. Improved separation of the segments from the core is achieved because the sabot is constructed so that the severable band is the initial mechanism for retaining the sabot segments on the core during feeding and chambering. The separation lines between the core and sabot segments are pre-established by molding alternate segments in two sequential steps. Also, the segments are mechanically locked together, providing a predictable separation mechanism.
