An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a switching device that detects a chemical compositional component as a switching property of a switching signal that is transmitted to the detonator system, with the switching device being capable of switching the initiating device, on detection of the chemical compositional component, to a standby condition in which the initiating device accepts the detonation initiating signal when it is transmitted thereto. |

Method and device for mixing and initiating a pyrotechnic charge, comprising at least one coherent porous fuel structure (16) and at least one oxidizer (8). According to the invention, the coherent porous fuel structure (16) and the oxidizer (8) are placed apart in a mixing device (1, 20) to prevent unintentional ignition, and in which the oxidizer (8), in response to the action of a force upon the mixing device (1, 20), for example upon firing of an artillery shell, is transported into the coherent porous fuel structure (16), after which the obtained pyrotechnic charge is initiated after a set time delay. |

An apparatus for the generation of electricity that may be in a “standby” mode for long periods of time, i.e. many years. Thus, in one embodiment of the invention, a fuel cell may include at least one of the following features or components: a membrane, and/or storage tanks or cells for hydrogen and oxygen, and/or an “inertial” switch, which may optionally be assembled in close proximity to a membrane. The inertial switch, when activated, may rupture the membrane and allow the hydrogen and oxygen to mix in a fuel cell. |

A safe and arm device, which has an explosive train interrupted by a void establish a safe condition, has the void filled with a liquid explosive to establish an armed condition. The void may be in a device in which the liquid explosive is motivated by fluid pressure corresponding to free-fall or other velocities. The void may be a chamber portion filled with the liquid explosive by expansion of a bladder. Premature arming may be prevented by forming the explosive liquid from nonexplosive liquids mixed by rupture of a bladder or by melting a solid explosive. |

An arming fuze for ordnance type munitions having but one movable part comprising a solvent desensitized liquid explosive contained in a ported (ventilated) cavity that is normally sealed by a sleeve. Upon movement of the sleeve and exposure of the liquid explosive within the cavity to the air, the liquid explosive loses a volatile solvent, the desensitizing agent, and becomes progressively more sensitive. A first embodiment is that of an inertia armed nose fuze for a projectile wherein the desensitized liquid explosive is enclosed in the cavity in a porous solid matrix. Upon rapid acceleration, as when the projectile is fired, the sleeve undergoes set-back thereby exposing the porous matrix to a violent slip stream of air and to a strong desiccating action. The liquid explosive rapidly loses solvent to the air, rapidly becoming more sensitive whereby it is impact sensitive by the time impact on the target occurs. A second embodiment is that of a contact fuze for mine munitions wherein the fuze is armed by manually moving the sleeve to uncover the ventilation ports thereby to allow the solvent to leave the explosive liquid. When the explosive liquid has "dried", it is rendered sensitive to pressure or shock whereby detonation occurs upon striking or crushing the fuze. |

An arming fuze for ordnance type munitions having but one movable part comprising a solvent desensitized liquid explosive contained in a ported (ventillated) cavity that is normally sealed by a sleeve.

An article for use as a solution releasing control device in a fluid conting medium, such as air containing water vapor, is provided including an inner material composed of solid substance capable of sorbing this fluid and also capable of dissolving in this sorbed fluid, for example a hygroscopic, deliquescent agent such as lithium chloride or a mixture of lithium chloride and the tetrasodium salt of ethylenediaminetetraacetic acid. This inner material is enclosed in a container fabricated of a material which is substantially impermeable to the fluid in the medium surrounding it and is substantially nonwettable by the solution formed from the sorbed fluid and the sorbing agent, for example an essentially hydrophobic film, such as polyethylene. The container is provided with perforations of pre-determined number and size to provide an accurately controlled fluid sorbing and solution releasing device. |

Disclosed is a chemiluminescent ordnance timer. The device comprises essentially of a first ampule which contains a first reactive component, a second ampule containing a second reactive component, a mixing chamber for receiving both reactive components and for transmitting chemiluninescent light which is created by the mixture, a plurality of capillary tubes for imparting a predetermined time delay to the reactive components on their way to the mixing chamber, and finally, means for detecting the chemiluminescent light and for actuating an appropriate mechanism. Each of the ampules containing the reactive components are designed to break upon the application of a predetermined force such as a setback or a spin force which may be encountered in a projectile. Several safety features in the form of fluid sump means are provided along the capillary path to ensure that the detonator will activate only upon a predetermined sequence of events.

SELF-STERILIZATION CAPABILITY IS IMPARTED TO A CHEMICALLY ORIENTED MINE BY THE INCORPORATION INTO THE ACTIVE EXPLOSIVE OF A MATERIAL WHICH IS HYGROSCOPIC AND DELIQUESCENT. THE LATTER MATERIAL ABSORBS MOISTURE FROM THE ATMOSPHERE AND DELIQUESCES INTO AN AQUEOUS SOLUTION WHICH REACTS WITH THE ACTIVE EXPLOSIVE RENDERING IT LESS SENSITIVE AND ULTIMATELY STERILIZED AND SAFE TO HANDLE.
