Abstract: A Metal-Clad cable includes at least two conductor assemblies and a non-linear bonding/grounding conductor within a metal sheath. Each conductor assembly has an electrical conductor, an insulation layer extending around and along the length of each of the electrical conductors, a jacket layer disposed around the insulating layer and a polymeric protective layer disposed around the jacket layer along the length of each of the electrical conductors. The bonding/grounding conductor includes a plurality of undulations disposed along a length thereof, and is disposed within the metal sheath so that it is in contact with an interior surface of the metal sheath. The bonding/grounding conductor is in cabled relation with the conductor assemblies. The undulations of the bonding/grounding conductor provide a degree of resiliency to the connection between the conductors and the metal sheath to facilitate easy removal of the metal sheath when making terminal connections.

Abstract: A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16) with a cartridge case (26) therein and countermass main body (18) movable in opposite directions. Gas from a deflagrating propellant moves the movable members and applies directionally opposite forces upon the breech end surface (40) and the stand pressure surface (32), which results in the force cancellation and ensures that the barrel (12) remains stable during firing. This solves the problem of the angle of departure and contributes to a high accuracy of shooting.
Abstract: A method of firing of arms which utilizes both action and reaction forces in the process of firing. The action force propels the projectile (14) while the opposite in direction reaction force is used with an independent freely moving inert mass (20) in which a cartridge case (18) resides. Since the movement of the inert mass (20) does not affect the position of the barrel (12) prior to the projectile (14) leaving the muzzle, the barrel (12) remains steady during firing, thus achieving very high accuracy of shooting.
