Patent number: 5580515Abstract: An igniter for an exothermic lance has an inner peripheral wall about the lance, the inner peripheral wall defining dual purpose teeth for centering the lance relative to the igniter and holding various lances of differing diameters. The teeth space the inner wall from the lance so as to form a flue between the inner wall and the lance. Outside the inner peripheral wall and concentric therewith is an outer peripheral wall thicker than the inner wall. A flammable substance is between the inner and outer walls, the flammable substance being more rapidly combustible than the inner wall and outer walls. A match head element at the fore end of the igniter is the mechanism to initiate combustion of the flammable substance, which can be a Thermit mixture. A gap between the match head element and the lance allows oxygen from the lance to enter the flue and accelerate lance ignition.Type: GrantFiled: August 22, 1995Date of Patent: December 3, 1996Inventor: Paul A.

Patent number: 5388500Abstract: Applicant's device improves rapidly firing guns. When such a gun fires, applicant's device delays departure of the gun bolt from the chamber or barrel zone holding a spent round's casing until barrel pressure drops to a safe level. The device has a hollow piston which is translatable fore and aft along the barrel and which has an orifice communicated to a duct from an inner barrel diameter to an outer barrel diameter. The duct slants forward toward the gun muzzle in a radially outward direction so as to direct expanding propellant gas from the barrel against a forward internal surface of the piston. Momentum of the gas keeps the piston in its most forward position and the piston solidly connects to the bolt so that the bolt stays at the chamber when the piston is pressurized.Type: GrantFiled: March 7, 1994Date of Patent: February 14, 1995Inventor: Paul A.

Patent number: 5365853Abstract: Disclosed is a projectile that has high velocity at short range. The projectile has a body of material that is lighter, more lubricous and more deformable than a partial Jacket on the rearward portion of the projectile. The jacket defines an annular array of apertures on the outer diametrical surface of the jacket and the body has peripheral zones that extend into the apertures far enough to be flush with the outer diametrical surface. The peripheral zones not only provide a physical lock between the body and jacket but also lubricate the interface between the projectile and the gun barrel along which the projectile travels during firing of a gun. The apertures are configured to allow the body to erupt radially outward through the jacket's side wall and form a relatively wide, shallow dispersal pattern when the projectile impacts a target. An optional core within the plastic body enhances the body's radially outward dispersal upon the projectile's impact with a target.Type: GrantFiled: February 14, 1994Date of Patent: November 22, 1994Inventors: Robert M. Petrovich, Paul A. Petrovich
