Abstract: A cartridge includes a segmented elastomeric projectile and associated motion transfer member. The motion transfer member includes a cutting surface to separate the projectile segments when deployed. In a preferred embodiment, a cartridge includes a plurality of segmented elastomeric projectiles, each with its own motion transfer member. A piston element which is deployed by expanding gases, includes a force transfer element which engages an overlying motion transfer member which, in turn, engages its overlying transfer member. As each transfer member engages an overlying transfer member, its projectile is severed into its constituent segments.

Abstract: A highly pliant projectile intended to be deployed from a firearm is adapted to be elongated during transit through the firearm. The propellant gases act upon a piston element which is coupled to a force transfer member that is positioned in a cavity within the projectile body so that propulsion forces are applied to the forwardmost part of the projectile, causing it to elongate, thereby reducing its diameter so as not to interfere with the walls of the firearm.

Abstract: A less lethal ammunition round (10) includes a highly pliant projectile (24) that may impregnated with fine heavy particles. The projectile has an interior void (32) into which is placed a force transfer member (30) that engages an interior surface at the forward end of the projectile in front of the center of gravity. Upon ignition of a powder charge, a piston (26) in the cartridge chamber engages the transfer member which, in turn, elongates the projectile as the projectile forward end is driven, pulling the remainder of the projectile, reducing its diameter. This allows a release from the cartridge and passage through the barrel of the weapon from which it is being fired. Stabilizing fins (39) at the projectile base deploy as the projectile exits the muzzle. A breaching round is impregnated with a greater weight of heavy particles and its transfer member has an initial large diameter portion and a terminal smaller diameter portion.

Abstract: A demountable door securing device includes a door edge engaging plate with a right angled bend adapted to rest against one face of the door and an extended portion terminating in a hinge on the opposite side of the door. A rotating door engaging member including a planar portion and a right angled portion can be rotated to engage a face of the door. A security bar through apertured tabs in the extended portion prevents rotation of the planar portion. The right angled bend includes an extended bar portion parallel to the door face at the free end of which a hasp is pivotally mounted. The hasp rotates into engagement with the door frame and is held in place by a securing bar extending outward from the right angled bend. A tongue on the free end of the securing bar fits through an aperture in the hasp and holes in the tongue can receive a locking device.

Abstract: A protective casing for removably retaining an environment-sensitive object such as a recording tape cartridge or a tape cassette and protecting such object from contamination as by dirt, dust, magnetic radiation, humidity, and temperature. The illustrated casing comprises rectangularly shaped upper and lower case sections which are hingedly connected together along one edge and maintained in that relationship by means of an elongated resilient wire torsion spring. The spring and portions of the case section edges combine to form the hinge for the casing. The case sections form a "clam-shell" construction, with the spring also serving to continuously bias the sections to a closed position against one another. The case may be manually opened and held open against the biasing force of the spring which will automatically reclose the casing as soon as it is released.
