Abstract: An omni-directional recoil energy absorption mechanism has a slipping disk supported by a support plate carrying a weapon; and a cover plate covering the slipping disk and capturing it to create a sandwich structure of cover plate, slipping disk and support plate. Bolts act in conjunction with pressure springs to press the cover plate to the slipping disk toward the support plate and create friction forces in a plane of the slipping disk. Tension springs connect the slipping disk to the support plate under recoil force configured to return the slipping disk and the weapon to an initial position, in a center of the support and cover plates. The springs are preloaded to a pre-defined level to oppose, flexibly, the recoil forces in any vertical and radial directions, while absorbing the recoil energy by allowing the slipping of the slipping disk in between the cover and support plates.

Abstract: The invention relates to safety components/modifications for a firearm barrel for preventing discharge of live ammunition from the firearm. The invention includes one embodiment of a modified barrel including a rod member transversely positioned within a portion of the bore of the barrel adjacent to the chamber to prevent chambering or loading of a live round. The modified barrel further includes a standard blank-firing adapter (BFA) fixedly coupled to the distal or muzzle end of the barrel.

Abstract: A simple ammunition casing resizer helps eliminate the problem of the casing becoming frictionally stuck with the resizing die. The ammunition casing resizer is a table top secured base that has a die plate located above the base with the resizing die removably secured within the die plate. A resizing frame reciprocates in up and down fashion under the guidance of either a manually controlled handle or an electrical motor. A ram is positioned below the resizing die while a push rod is positioned above the die such that the ram and push rod, each attached to the frame, travel in up and down reciprocating lockstep. As the ram travels upwardly, the ram presses a casing into the die for resizing and as the ram travels downwardly, the push rod passes through the top of the die and into the interior of the casing, pushing the casing out of the die.

Abstract: A linking device has a bearing and is suitable for use with a weapons system. The device provides adjustable rotational resisting torque of two coaxial cylindrical parts which are rotatable relative to one another about a shared axis. The bearing includes two rings made of a resiliently deformable material and is capable of respectively engaging with the two cylindrical portions, and between which rolling elements are arranged such as to be in contact with raceways of said rings. The device further includes a controllable member for adjusting the tightening of the rings, wherein the controllable member is capable of engaging one of said parts in order to engage with said bearing.

Abstract: Mine neutralization provides for radio control of a small boat having associated therewith: a projection mounted onto the boat and pointing forward; a primary magnet; a housing holding the primary magnet and joined at the front end of the projection; a fluid-dynamically shaped explosive device detachably attached underneath the boat; at least one secondary magnet affixed to the explosive device; and, a rope or cable tautly connected at its upper end to the primary magnet and at its lower end to the explosive device. The boat journeys near a floating mine to bring about magnetic interaction between the primary magnet and the mine. The primary magnet magnetically attaches to the mine, and a pulling force is exerted on the explosive device. The explosive device detaches from the boat, moves toward the mine, and magnetically attaches (via at least one secondary magnet) to the mine.

Abstract: A toy launch apparatus for discharging soft foam darts, the launch apparatus having a cylinder, a piston, a launch spring and a dart tube. An air chamber with variable volume is formed between the cylinder and the piston and is divided into two or more sections, a first section where there is little or no resistance to relative movement between the cylinder and the piston so that there is a momentum gain, and a second section where there is rapid compression and increasing pressure to cause a loaded dart to be discharged.

Abstract: An adjustable free-float forend/handguard mounting assembly for a small arms weapon, for attaching a forend/handguard to the small arms weapon.
