Patent number: 11021936Abstract: 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.

Patent number: 10229756Abstract: 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.Type: GrantFiled: August 22, 2014Date of Patent: March 12, 2019Assignees: PRINCETON SATELLITE SYSTEMS, INC., THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Michael A.

Patent number: 7771549Abstract: 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.Type: GrantFiled: October 7, 2003Date of Patent: August 10, 2010Assignee: United States of America as represented by the Secretary of the Air ForceInventors: Karl O. Christe, Greg W. Drake

Patent number: 7763133Abstract: 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.Type: GrantFiled: March 26, 2004Date of Patent: July 27, 2010Assignee: Orica Explosives Technology Pty Ltd.Inventor: Stephen Thomson

Patent number: 7749344Abstract: 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.Type: GrantFiled: February 27, 2007Date of Patent: July 6, 2010Assignee: CFO Research CorporationInventor: Debasis Sengupta
