  • Patent number: 11021936
    Abstract: Electrically ignitable and electrically controllable explosive material (EIECEM) may be disposed within a shaped charge for deployment downhole. An explosion of the EIECEM is controlled by limiting the duration of excitation at the EIECEM, for example, the duration that an electrical source provides an electrical charge, electrical current or electrical signal. The shaped charge may be insulated from an electrical source to prevent explosion of the EIECEM and coupled to the electrical source to create ignite or explode the EIECEM. A plurality of shaped charges may be disposed downhole and may be ignited or exploded in any suitable order. The EIECEM may be ignited multiple times such that multiple explosions are created. The explosion of the EIECEM creates or extends a perforation or fracture in a formation. The shaped charges may be excited in a predetermined sequence and for a predetermined duration of time.

  • Patent number: 10229756
    Abstract: The invention is for a startup system for nuclear fusion engines in space. The combustion of hydrogen and oxygen produces heat that is used by a heat engine to produce electricity. This can be supplemented by electricity from other operating engines. The exhaust from the combustion is condensed and electrolyzed to produce hydrogen and oxygen once the engine is in operation. This provides a constant source of energy for future startups. The engine is started up at partial power in electricity generation mode and this power replaces the power from the combustion as it grows. The combustor uses the same heat engine as the nuclear engine uses for power generation.

    Abstract: Oligoesters including residues of alk(en)yl succinic anhydrides and polyols having at least 3 OH groups, optionally further esterified with fatty acid residues are surfactants which can be used for emulsifiers or similar uses. The surfactants are usually made from C8 to C30 alk(en)yl succinic anhydride and polyols having at least 4 hydroxyl groups and are particularly of the formula (I): R1—[OR2O(O)C.C(HR3).(HR4)C.C(O)]m—R5 (I), where R1, R2, R3, R4, R5, R6, R7 and m have defined meanings. The surfactants are useful as emulsifiers, particuarly oil in water emulsifiers.

  • Publication number: 20100269964
    Abstract: An explosive device and methods for forming same, the device comprising a portion of nitrous oxide and a portion of fuel. In one example, the explosive device may include a first storage area containing said portion of nitrous oxide, and a second storage area containing said portion of fuel, wherein the first storage area selectively maintains the portion of nitrous oxide separated from the fuel in the second storage area prior to detonation of the explosive device. In another example, in the event the explosive fails to detonate, the explosive device may include a vent valve for discharging the nitrous oxide from the explosive device to reduce or eliminate its explosive characteristics. The explosive device can be used for various applications, including but not limited to military weapons, pyrotechnic devices, or civil blasting explosives, for example.

  • Patent number: 7807000
    Abstract: A thermobaric explosive composition is provided that includes coated fuel particle, a nitramine, and binder. The coated fuel particles preferably have a magnesium core and an aluminum coating. Upon detonation, the nitramine disperses the coated fuel particles over a blast area during a first overpressure stage. The aluminum coating of the fuel particles has a thickness selected to provide an amount of aluminum that is stoichiometrically less than an amount of ambient-air oxygen available in the blast area for aerobic combustion with the aluminum during the first overpressure stage. Once exposed, the magnesium cores may combust to increase the impulse generated in the first overpressure stage. Also provided are articles of manufacture and related methods.

  • Patent number: 7771549
    Abstract: Provided are energetic materials of low vapor pressure in the form of ionic liquids having fuel and oxidizer ions including, substituted pyridinium or imidazolium cations paired with nitrato-, perchlorato-, or nitramido-based anions, to form such ionic liquids or salts. The salts of the present invention are low melting and have essentially little or no vapor pressure over a wide temperature range. The salts of this invention are thus an important breakthrough since they can serve as high-performing monopropellants which are not complex mixtures and have no vapor toxicity. Such salts also find use as munitions, liquid explosives, reaction media for the synthesis of other high-energy materials, and as plasticizers.

  • Patent number: 7763133
    Abstract: A method of transporting a liquid product down a vertical conduit having an inlet provided at the top of the conduit and an outlet provided at the bottom of the conduit, which method comprises feeding the liquid product into the inlet of the conduit and contacting the liquid product with means for dissipating potential energy released by the liquid product as it is transported down the conduit so that turbulence in the liquid product at the outlet of the conduit is reduced.

  • Patent number: 7749344
    Abstract: Disclosed is a group of tertiary amine azides useful as hypergolic fuels for hypergolic bipropellant mixtures. The fuels provide higher density impulses than monomethyl hydrazine (MMH) but are less toxic and have lower vapor pressures that MMH. In addition, the fuels have shorter ignition delay times than dimethylaminoethylazide (DMAZ) and other potential reduced toxicity replacements for MMH.
