  • Patent number: 11835326
    Abstract: The invention relates to an igniter with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter has, in a delay section, preferably in the fuse head, a relief bore that can be closed or opened.

  • Publication number: 20230003497
    Abstract: An igniter system for a piece of ammunition, having at least one propellant igniter and at least one igniter element designed for transmitting ignition power and extending away from the propellant igniter. The igniter element is arranged spaced apart from the propellant igniter.

  • Patent number: 10889530
    Abstract: A pyrotechnic delayed-action composition and primer charge made of REACh-compliant components that are safe for humans and the environment. The delayed-action composition comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. The performance parameters thereof, in particular the burning time, can be set variably within a wide range. The composition clinkers on its own, thus preventing extinction at the front of the burning material even in dynamic conditions. The primer charge comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. It is easy to ignite and, due to its clinker structure, transfers its energy well to the compositions to be ignited. The delayed-action composition and the primer charge have the same structure and can easily be combined and adapted to each other in delayed-action units.

  • 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.
