  • Publication number: 20240118062
    Abstract: The present disclosure relates to a pyrotechnic object, in particular an irritation body, irritation projectile or ammunition, comprising an ignition device, comprising a delay chamber extending along a delay path, in which chamber a delay charge is accommodated, and comprising at least one and preferably a plurality of effect chambers in which or in each of which an effect charge to be ignited is accommodated, wherein the delay chamber is transversely connected to a respective effect chamber via a respective over-ignition opening which branches off from the delay chamber and forms an over-ignition path, wherein in the case of a plurality of effect chambers the plurality of over-ignition openings are arranged successively downstream along the delay path in the order of the effect charges to be ignited.

  • 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.

  • 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.
