  • Publication number: 20140373983
    Abstract: A process of producing an infrared radiation-generating decoy for protecting against heat-seeking missiles and other heat-seeking devices comprises the step of decomposing a metal carboxy compound in the substantial absence of gaseous oxygen, to produce a pyrophoric material as a decomposition product of the metal carboxy compound, which pyrophoric material is arranged to combust spontaneously upon contact with air when the decoy is used. The metal carboxy compound may be iron oxalate, and the pyrophoric material may be ferrous oxide. The pyrophoric material may be coated onto a substrate, and a plurality of coated substrate pieces may be used in a decoy.

  • Publication number: 20140373984
    Abstract: Disclosed are hypergolic salts with borane cluster anions that ignite spontaneously upon contact with nitric acid (from 70% to 100% in water) with short ignition delay. The salts, when added as trigger additive to combustible solvent or ionic liquids, make the resulting formulation hypergolic. The salts with borane cluster anions also shorten ignition delay in hypergols, such as RP-1, and additionally allow nitric acid to be used to replace liquid oxygen as an oxidizer. In some examples, the borane salts are formed in situ in an ionic liquid.

    Abstract: This invention relates to the construction of a rocket motor and fuel system thereof and, in particular to a new and useful Viscous Liquid Monopropellant (VLM) rocket motor containing a liquid propellant that is pumped into the combustion chamber, atomised and then ignited. The atomisation step significantly increases the surface area of the propellant, delivering faster burn rates and smoother combustion. VLM is a non-Newtonian fluid containing both oxidisers and fuels. These monopropellants are comprised of a variety of liquid and solid components, mixed together to form a homogenous fluid, although heterogeneous in composition. The solid constituents are retained within the liquid phase by dispersion, suspension, bonding or chemical emulsification techniques, so as when a motive force is applied to the propellant, all the constituents are also transported, and held in correct proportion whilst doing so.

  • Patent number: 7707819
    Abstract: Hollow RX-08HD cylindrical charges were loaded with boron and PTFE, in the form of low-bulk density powders or powders dispersed in a rigid foam matrix. Each charge was initiated by a Comp B booster at one end, producing a detonation wave propagating down the length of the cylinder, crushing the foam or bulk powder and collapsing the void spaces. The PdV work done in crushing the material heated it to high temperatures, expelling it in a high velocity fluid jet. In the case of boron particles supported in foam, framing camera photos, temperature measurements, and aluminum witness plates suggest that the boron was completely vaporized by the crush wave and that the boron vapor turbulently mixed with and burned in the surrounding air.

  • Patent number: 6843868
    Abstract: A non-/low-toxic, non-hypergolic, propellant formulation generally comprising metal nanoparticles, such as boron, aluminum, or carbon, and one or more fluoro-polymers mixed in in particulate form. The present invention takes advantage of the increased surface area provided by nano-sized metallic particles to enhance the metal's combustion efficiency, or ignitability. The inclusion of fluoro-polymers also aids in increasing the combustion efficiency of the metallic nanoparticles due to the presence of halogenic oxidizers. The thermal degradation of a halogenated fluoro-polymer additive in the propellant combustion zone serves to release halogens, thereby improving the combustion of the metallic nanoparticles and increasing the propulsion system's energy output. The present invention's formulation is safe to store and handle, environmentally-friendly, and may be economically manufactured to provide for widespread, cost-effective use.

  • Publication number: 20040231768
    Abstract: The invention relates to a pyrotechnical composition which is intended both for a hybrid gas-generating material and for a purely pyrotechnical gas-generating material for use in gas-actuated car safety devices, and which comprises a first obligatory constituent in the form of 5-95 wt % of guanyl urea dinitramide and a second obligatory constituent in the form of 5-50 wt % of an oxidizing agent (calculated on the total amount of solids), together with—if it is necessary to increase the rate of burning—a combustion moderator in the form of 0-90 wt % of guanidine dinitramide or up to 10 wt % of finely divided metallic boron, as well as up to 10 wt % of a binder. The pyrotechnical composition according to the invention is characterized e.g. by a low pollutant emission, low smoke formation, and the fact that its rate of burning can be adjusted to suit any type of car safety device by varying the ratio between the constituents within the limits specified in the invention.

  • Patent number: 6723190
    Abstract: A communication system comprises an input-output processor IOP (11) coupled to a plurality of network devices (10) and a protocol processor PP (12), both processors being coupled to a common memory (15). Memory access control means (16) resolves competition between the processors for memory access. Normally, if one of the two processors is accessing the memory, the memory control unit (16) allows that access to be completed before allowing the other processor to access the memory. But if data loss in a network device is imminent, the IOP, is granted a higher priority memory access, the memory access controller aborts (interrupts) any memory access by the PP, allowing the IOP to access the memory immediately.

  • Publication number: 20040045647
    Abstract: A method of folding a gas bag for a vehicle occupant restraint system comprises the following steps: first, the gas bag is unfolded between a base and an opposing surface. A spacing is provided between the base and the opposing surface, which corresponds to a height of a housing into which the gas bag is to be inserted after folding. Then, a folding funnel is provided which comprises one end having a large cross-section and one end having a small cross-section, the large cross-section being larger than or equal to a cross-section of the gas bag when unfolded between the base and the opposing surface, and the small cross-section corresponding to a cross-section of the housing; beginning with its large cross-section. Finally, the folding funnel is placed over the unfolded gas bag and moved relative thereto such that the gas bag is pushed together on the base by the folding funnel to the small cross-section.

  • Patent number: 6652682
    Abstract: The present invention is a propellant composition comprising from about 2 percent to about 46 percent, by weight, boron particles having a diameter of less than about 500 nanometers. Liquid or gel embodiments of the invention may also include adding the boron particles to a liquid fuel in order to form a liquid fuel system. Examples of such liquid fuels include ethyl ammonium nitrate (EAN), triethyl amine nitrate (TEAN), Cyclotetramethylenetetranitramine (HMX), trinitrotoluene (TNT), jet fuel formula (JP-10), kerosene, RJ-4, or other hydrocarbon based fuels. These liquid fuel systems can be part of bipropellants wherein the liquid fuel system is stored separately from an oxidizing agent and the two are mixed during operation. Examples of oxidizing agents may include nitrogen tetroxide, oxygen, hydrogen peroxide, hydroxyl ammonium perchlorate (HAP), hydoxyl ammonium nitrate (HAN), ammonium perchlorate, ammonium nitrate, ammonium dinitramide (ADN), or a combination of said chemicals.

  • Patent number: 6562497
    Abstract: A new fuel composition useful for catalytic fuel cells is made up of at least two components. The primary fuel component is a surface-active compound, such as methanol, that is a source of and acts to prevent unwanted decomposition of the auxiliary fuel. The auxiliary fuel is a hydrogen-containing inorganic compound with a high reduction potential, such as NaBH4, which acts as a highly reactive source of energy and serves to catalyze the catalytic oxidation of the primary fuel.
