Abstract: A device for capturing humans or animals, comprises a pair of projectiles each having a forward head and a rear shank. Each shank is semi-cylindrical and offset to one side of its associated head, such that when the projectiles are placed together with their shanks contiguous to each other, the two shanks together form a cylindrical body and the two heads together form a flattened body disposed in a plane perpendicular to a mating plane of the two shanks. A flexible tether interconnects the two projectiles, whereby when the two shanks are disposed contiguous to each other and inserted in the bore of the barrel of a firearm, and the firearm is fired, the two shanks will impart thrust to their respective projectiles along lines of force disposed to one side of a center of gravity of each projectile.

Abstract: The invention comprises a package having a pair of concave mating portions and an elastic membrane secured in elastic tension to the periphery of the mouth of each mating portion, the tension being such as to permit the positioning of articles between the membranes. The package is adapted to function as a fluid damped device in which damping results from restricted gas flow and in which the membranes act as a damped compound spring to protect articles positioned therebetween from mechanical shock and vibration.
