  • Patent number: 10955226
    Abstract: A hand grenade for producing smoke, having a housing provided with outflow openings for the smoke to be produced. The hand grenade also has a fuse head having an igniter for igniting the hand grenade and an ignition and delay line. An active charge can be ignited via the fuse head and the ignition and delay line, creating a carrier gas in the housing. An effect region is also provided in the hand grenade, by means of which at least one effect module of the hand grenade can be supplied. The effect module contains an active ingredient that can be converted into its gaseous state of aggregation by the action of heat and can flow out of the outflow openings with the carrier gas.

  • Patent number: 9513094
    Abstract: An ammunition is proposed with an explosive-free missile that releases, upon dismantling at the target a fuel or fuel mixture as flammable air-fuel mixture, being caused to spontaneously react by at least one, by impact dismantling triggered, explosive-free, spark-generating ignition mechanism. The thus produced optical and thermal target signature can be detected with the naked eye, as well as with rifle scopes or other optical target detection systems, as well as with night-vision and thermal imaging devices.

  • Patent number: 8888936
    Abstract: A powdery pyrotechnic mixture is proposed that comprises a binary or ternary inorganic oxidizing agent mixture composed of one or two metal oxides, a nitrate totaling 50.0% by weight to 85.0% by weight, an elementary inorganic fuel or a mixture of elementary inorganic fuels totaling 15.0% by weight to 40.0% by weight, a stabilized nitrocellulose or a nitrocellulose-based propellant powder from 0.0% by weight to 25.0% by weight, graphite from 0.0% by weight to 5.0% by weight as well as. Optionally. a further processing aid from 0.0% by weight to 5.0% by weight. The powdery pyrotechnic mixture excels in that it contains no chlorate-containing compound and/or perchlorate-containing compound as an oxidizing agent and no sulfur or a sulfur-containing compound as fuel. The proposed pyrotechnic mixture is used in pyrotechnic objects and ammunition for the production of a bang-effect and/or flash effect.

  • Publication number: 20120272853
    Abstract: A plastic-bonded pyrotechnical mixture is provided that includes at least one oxidatizer, one carbonate and/or phosphate from the group of alkali metals or earth alkali metals, a chlorinated rubber and a softener. An additional bonding agent and/or graphite can be added thereto as needed. The oxidatizer can be a perchlorate or a mixture of perchlorates from the group of alkali metals or earth alkali metals, or alternatively, ammonium perchlorates can also be integrated as an oxidatizer. The softener is an organic substance or substance mixture from the group of adipates or phthalates, or can be an organic phosphoric acid ester or a phosphoric acid ester mixture. As an additional bonding agent, an organic titanate or an organic titanate mixture is preferred. All components are mixed with one another at such a ratio that a neutral smoke in the pH range of 5-7 (bases on aerosol) is created.

  • Patent number: 6216196
    Abstract: A computer system for controlling the operation of a multifunction device, including a central processing unit, a memory device connected to the central processing unit, a plurality of device drivers, wherein each of the plurality of device drivers issues commands to control the multifunction device and an arbitration mechanism connected to the plurality of device drivers and further connected to the multifunction device, wherein commands issued by the plurality of device drivers are received by the arbitration mechanism, and wherein the arbitration mechanism determines a sequence for the commands to be issued to the multifunction device.
