Abstract:
A partially combustible propellant charge igniter in which combustible ignition-conducting tubes can be more advantageously separated. The igniter includes a metallic bottom piece accommodating an igniter charge therein, a centrally arranged ignition gas guide chamber in communication with the igniter charge for guiding ignition gas therefrom and a combustible ignition-conducting tube accommodating a propagation charge. The ignition-conducting tube is inserted into the bottom piece and extends outwardly therefrom with the propagation charge being arranged in the region of the ignition-conducting tube which extends outwardly from the bottom piece. The igniter includes at least one cavity accommodating a separating charge and being at least partially delimited by a wall of the ignition gas guide chamber and the ignition-conducting tube inserted in the bottom piece, and a nozzle for establishing a communicating connection of the cavity to the portion of the ignition-conducting tube accommodating the propagation charge. The nozzle enables the escape of gases produced by the separating charge after ignition of the separating charge.
Abstract:
An arrangement for the contactless transmission of electrical energy to a missile during the firing thereof from a firing device including a transformer-like coil system having a primary coil system connected to the firing device and a secondary coil system connected to the missile. The primary coil system is supplied with electric energy and the secondary coil system is responsive to the electric energy developed in the primary coil system for developing electrical energy therein. A partition is arranged between the primary coil system and the secondary coil system and is formed of a nonmagnetic material capable of withstanding thermal and mechanical stresses of repeated firings by the firing device. The partition is fixedly connected with the firing device and disposed for sealing the primary coil system with respect to the missile at least during the firing of the missile from the firing device.

The invention relates to a pyromechanical disconnecting device, especially for disconnecting the battery in a motor vehicle. Said device comprises a housing (1) in which a current conductor rail is arranged, said rail being configured in such a way that it can be disconnected by a slitting chisel (6) in a disconnecting point, wherein the slitting chisel (6) can be accelerated by the propelling gases of an ignition element (5) and the ignition element (5) has electrical connecting pins (9). Said ignition element is arranged in the locating area (7) in the housing (1) and is supported on a support bottom (2) of said locating area (7). The support bottom (2) has passage holes (3) for the connecting pins (9). In order to provide easy and safe installation of the ignition element in the disconnecting device, an elastic sealing element (4) is arranged between the ignition element (5) and the support bottom (2).
Abstract:
What is described is the use of a microjet reactor for the production of initiating explosive, each of the starting solutions for explosive production in the microjet reactor being injected through a nozzle onto a common collision point into a reactor space enclosed by a reactor housing, a gas being admitted into the reactor space via an opening, and the resulting initiating explosive crystals being removed from the reactor housing together with the liquid and excess gas through a further opening.
Abstract:
The invention relates to a method for producing a cartridge consisting of a case and a projectile, characterized in that, once the cartridge is fully manufactured, a capillary active, acrylate-based adhesive sealing agent is applied in a controlled manner to the gap arising in the inner mouth of the case when the projectile is inserted therein, in a sufficient quantity as to guarantee full sealing of said gap.
Abstract:
Gas generator for an inflatable impact cushion for protecting an occupant of a motor-vehicle from injury, has a housing, in which is formed a storage chamber for liquid gas. The storage chamber is separated by a partition wall from a combustion chamber also formed in the housing. An ignition device is positioned in a precombustion chamber, and has an ignition charge to generate combustion gases during ignition. In the precombustion chamber there is guided, in a displaceable manner, a piston which, because of the combustion gases of the ignition charge, moves into and through the combustion chamber in a direction of the partition wall, in order to penetrate the partition wall. When the partition wall is penetrated there is a connection between the storage chamber and the combustion chamber by way of a liquid gas channel system so that liquid gas can flow into the combustion chamber. At the same time a connection is created between the precombustion chamber and the (main) combustion chamber by way of ignition channels formed in the piston. The hot combustion gases of the ignition charge ignite the liquid gas flowing in. The rising internal pressure in the combustion chamber causes a displacement of the longitudinally displaceably guided partition wall, which moves together with the piston and thereby continuously injects liquid gas from the storage chamber into the combustion chamber. The combustion gases emerge by way of annular chambers, connected in series, through outlet openings in the housing.
Abstract:
A device for igniting a propellant charge is provided with a housing defining a cavity wherein a piston is displaceably guided. The cavity is connected via a bore acting as a nozzle to a chamber wherein a case member of a cartridge is arranged for accommodating the propellant charge. A bottom wall of the case member is equipped with a bore aligned with the bore acting as a nozzle. A primer wafer is disposed on the inner surface of the bottom wall, this wafer being thinner in its central zone than in its marginal zone. The central zone of the primer wafer is a region under mechanical thermal stress during compression, the ignition energy being introduced to the primer wafer via this region in the form of hot compressed air from the compression chamber.
Abstract:
The invention relates to a propellant charge igniter comprising at least two series-connected combustion chambers separated from one another by choke disks, respectively one igniter mixture being housed in these chambers, these igniter mixtures differing from one another with respect to their combustion characteristics and thus exhibiting differing combustion behavior. The combustion chamber volumes are adapted to these igniter mixtures so that the mixture can burn up at the pressure level that is an optimum for the mixtures in each case.
