  • Publication number: 20250035419
    Abstract: Rocket-assisted artillery rounds and methods for firing the same are described herein. In one example, a rocket-assisted artillery round includes a projectile body, rocket fuel disposed in the projectile body, an ignitor positioned to ignite the rocket fuel, and an ignition control system. The ignition control system includes a controller coupled to first and second sensors. The first sensor is configured to detect a first metric. The first metric is indicative of rotation of the projectile body. The second sensor is configured to detect a second metric. The second metric is indicative of setback of the projectile body. The controller is configured to output an activation signal to the ignitor based on the first metric and the second metric.

  • Patent number: 12202978
    Abstract: Methods of making a hybrid crude oil using man-made or natural petroleum-based waste stream products. The hybrid crude oil is composed of an oil-based solution and petroleum-based coatings that were extracted from a petroleum-containing material. This hybrid crude oil is created by elevating the temperature of the oil-based solution to or above an elevated temperature, i.e., the melting or phase-change temperature of the petroleum-based coating so that it can become liquified and dissolve into the oil-based solution and create the hybrid crude oil. The petroleum-containing material is submerged into the heated oil-based solution to cause the petroleum-based coatings to dissolve into the heated oil-based solution at the elevated temperature.

  • Patent number: 11892276
    Abstract: Embodiments of the present disclosure relate to the field of ammunition rounds for training or tactical purposes. In one or more embodiments, the projectile is equipped to transmit an improved visual signature upon impact, including one or both of flash and smoke signatures. In one example, a projectile includes a projectile body, an ogive coupled to the projectile body, and a boat tail having a degree of transparency coupled to the projectile body. The boat tail having a degree of transparency and the projectile body define a cavity within the boat tail having a degree of transparency and the projectile body. A flash producing material is disposed within the cavity.

  • Patent number: 10640712
    Abstract: A method is disclosed for the retrieval and recovery of organic-based or organic-containing materials, including naturally occurring substances such as crude oil, and other petroleum-based or containing materials, natural gas, and the like, from environments where they are entrained within or otherwise admixed or complexed with other organic or inorganic materials, such as rock, sand, shale and the like. The method comprises: retrieving a quantity of the petroleum-containing mixture, treating the petroleum-containing mixture with a solvent for the petroleum material to separate the petroleum material from the mixture, and recovering the separated petroleum-containing material. The solvent may be at approximately ambient temperature and may be, for instance, heptane, hexane, naphtha, kerosene, gasoline or a petroleum based solvent or any other suitable solvent in which the asphalt binder is soluble.

  • Patent number: 8997773
    Abstract: The present invention relates in general to a pressure discharge mechanism for closed vessels having an internal chamber designed to hold volatile and/or explosive substances in a sealed manner comprised of an at least one eutectic composition and a threaded joint designed to open or vent the closed vessel when the contents of the closed vessel reaches a predetermined temperature while maintaining full structural integrity during normal operation. In one aspect, the closed vessel is a munitions casing which functions as intended under normal operating environments, but then when exposed to extreme temperatures, reduces the munition's high order explosion capability, and is transformed into a safe, low order reaction with significantly less reactive potential. In one aspect, the closed vessel is a transport tanker which should not release substances contained therein. However, if the tanker catches fire, the pressure relief mechanism of the present invention reduces risk of explosion.

  • Patent number: 8776689
    Abstract: A detonator formed entirely from a plurality of discrete segments of an insensitive energetic composition, each of the segments employed in the detonator being compacted at different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments. Initiation of a main charge can only be effected when a last segment in the detonation train is initiated. Detonation starts with a first segment in the detonation train which is produced under the lowest compaction pressure, and then detonation progresses to a last segment compacted under a higher compaction pressure. The first segment can be detonated by a safety fuse or detonating cord, and the last segment can only be detonated by the next to the last segment in the detonation train.
