  • Patent number: 10220443
    Abstract: The invention relates to a method for producing a steel shaped body, particularly, for example, a component for common rail fuel injection valves, comprising the method steps of: forming a powderous composition based on iron oxide, from oxide particles, with the addition of carbon and micro-alloy elements so as to adjust a bainitic microstructure; heating the powderous composition to a sinter temperature; reducing the shaped body obtained by sintering; and cooling the sintered shaped body to room temperature. As a result, from the three essential state phases in a state diagram (10), specifically the ferrite-perlite state range (11), the bainite state range (12) and the martensite state range (13), preferably the bainitic state phase is formed in a medium temperature range by the ferrite-perlite state range (11) being shifted to longer cooling periods and the martensite state range (13) being shifted to lower temperatures.

  • Publication number: 20040231552
    Abstract: A method to increase the penetration of kinetic energy penetrating weapons designed to engage hardened and hardened deeply buried targets. The concept utilizes a projecting nose pin on the front of the penetrator to establish a terradynamic cavity similar to hydrodynamic cavities generated when certain projectiles penetrate water at velocities sufficient to penetrate in a supercavitation mode. The creation of a terradynamic cavity in which only the nose pin is in contact with the material being penetrated significantly reduces the drag of the penetrator enabling it to penetrate deeper into various media than other more conventional designs. The invention uses two modes of penetration. A guided mode is employed where the penetrator, with its projecting nose pin, normally would be unstable and is maintained stable in a straight-line trajectory utilizing an inverse, angle-angle rate guidance law and jet reaction control system.

  • Patent number: 6439127
    Abstract: A specially designed projectile is disclosed which provides an initial cruciform-shaped slit or cut, followed by the creation of a round hole into a target. This controlled entry creates a very high localized pressure during initial impact to a target for a very short duration, followed by a longer sustained lower-impact pressure. This creates a fragment-free hole into the container and can allow the projectile to penetrate sensitive explosives inside the container without shock-initiating or igniting the explosives. The projectile can disable bomb circuitry itself or provide a controlled entry hole to allow low-pressure water or other projectiles incapable of penetrating the steel container to enter freely. The leading end of the projectile can, with a high degree of accuracy, sever wires, destroy batteries, capacitors, and other components within a bomb or select military ordnance. The projectile can be used alone or in tandem with water or other disablement projectiles.

  • Patent number: 6305292
    Abstract: A bullet comprised of a jacket of malleable metal having a closed nose portion and a rear end portion defined by a cylindrical wall, the closed nose portion having wall-weakening areas encapsulating a forward core made of a deformable material which promptly deforms, collapses axially, and expands radially to a substantial extent along with the weakened wall areas, when the bullet strikes a target. The nose portion has wall-weakened areas which are ruptured by the core material to produce a collapsing and radially expanding action. These weakened wall areas are in the form of longitudinally extending, deep, internal or external, circumferentially spaced grooves with underlying web areas which are ruptured by the core material, to produce the collapsing and expanding action. This core is preferably made of rubber, urethane, silicone, or one of a substantial number of plastics, each of which has a hardness within a range of Shore A 20 to Rockwell 122.

  • Patent number: 6276277
    Abstract: A target-penetrating aerial bomb includes a penetrator of hard steel or similar material that contains an explosive charge. A rocket motor is formed as an annular chamber and surrounds the penetrator. The bomb includes a guidance and control unit that guides the bomb on a glide path after release from the delivery aircraft, and steers the bomb onto a dive line. Once the bomb is aligned on the dive line, the guidance and control unit fires the rocket booster to accelerate the bomb to the target. A fuse ignites the explosive after target penetration.

  • Patent number: 6244187
    Abstract: A mushrooming bullet having a highly improved performance in the retention of the lead core within the bullet jacket subsequent to impact, and in performing effectively over a substantially wider velocity range, the bullet retaining its lead core within its jacket substantially 98-100% of its firings at high velocities, and mushrooming more effectively at lower velocities than conventionally manufactured bullets. The jacket is characterized by a base portion which has a substantially larger interior diameter than its shank portion, and a mouth portion which is substantially softer than its shank portion. The mushrooming of the nose portion of the core and the mouth portion of the jacket is effectively arrested by the harder thick shank portion when the bullet strikes a target, and thereby minimizes the loss of lead from the core.

  • Patent number: 6240850
    Abstract: An improved bullet featuring a large, heavy non-aerodynamically shaped projectile that is to be used in short range life or death situations. This projectile and cartridge would be used in large game applications where the intent is not to fire unless in imminent danger. The projectile and cartridge combination of this invention would cause immediate destruction and transfer energy rapidly. The projectile is shaped to increase aerodynamic resistance by redirecting the displaced air into its preferred path. The large cross section and short body height further limit aerodynamic ability. The casing is machined from solid stock to provide a stronger more stable enclosure. This large diameter personal defense bullet uses a soft projectile body of high mass and improved shape, in conjunction with a high capacity casing of one piece precision machined construction to deliver maximum stopping power.

  • Patent number: 6186072
    Abstract: The present invention is a monolithic ballasted penetrator capable of delivering a working payload to a hardened target, such as reinforced concrete. The invention includes a ballast made from a dense heavy material insert and a monolithic case extending along an axis and consisting of a high-strength steel alloy. The case includes a nose end containing a hollow portion in which the ballast is nearly completely surrounded so that no movement of the ballast relative to the case is possible during impact with a hard target. The case is cast around the ballast, joining the two parts together. The ballast may contain concentric grooves or protrusions that improve joint strength between the case and ballast. The case further includes a second hollow portion; between the ballast and base, which has a payload fastened within this portion. The penetrator can be used to carry instrumentation to measure the geologic character of the earth, or properties of arctic ice, as they pass through it.

  • Patent number: 6085661
    Abstract: A small caliber non-toxic penetrator projectile has a first core and a second core tandemly aligned and enveloped by a jacket. The first core has a hardness greater than the hardness of the second core that has a Brinell hardness of between about 20 and about 50. The hardness of the second core is significantly higher than the hardness of lead and when the first core strikes a target, the second core resists compressive bulging. As a result, more kinetic energy is transferred to the first core rather than diffused along the surfaces of an armored target. The more efficient transfer of kinetic enables the use of lower density second cores, such as annealed copper.

  • Patent number: 6041712
    Abstract: The invention is a non lethal weapon cartridge comprising a projectile and means for propelling the projectile through a weapon barrel. A munition of this type can be employed by soldiers during operations-other-than-war, such as riot control during humanitarian missions, or by law enforcement personnel when a lethal response is not warranted. The projectile comprises a full-bore projectile body fitted with a compliant nose. The projectile is designed to be spin-stabilized such that it will fly, and impact, nose first, while describing a ballistic trajectory. The projectile is intended to be launched from a rifled weapon tube. The rifling imparts the spin necessary to achieve dynamic stability. The propulsion system utilizes a modern smokeless propellant in combination with a high-low technique to produce consistent interior ballistics.
