This disclosure relates to a plasma generation device particularly adapted to an electrothermal-chemical propulsion system. The device comprises a membranous conductive substance having structural compositions which enable the formation of a continuous and volumetrically distributed plasma arc. The membranous substance is versatile and operates, inter alia, as a fuse wire, plasma incubator, plasma container, plasma distributor, plasma infusion and permeation media as well as a fuel container.

Annular plasma injector

A firearm cartridge with a pre-pressurizing charge and a main propellant charge. The pre-pressurizing charge is located adjacent the rear end of the projectile. The pre-pressurizing charge can burn and exert pressure on the main propellant charge without igniting the main propellant charge.

Firearm cartridge with pre-pressurizing charge

A pressure vessel (12) contains a source of inflation fluid for inflating an inflatable vehicle occupant protection device (11). The pressure vessel (12) includes a surface (52) which defines a passage (54) for inflation fluid to flow from the pressure vessel (12) into the inflatable vehicle occupant protection device. A device (68 and/or 96) inside the pressure vessel (12) sends or receives electrical signals. An energy transmitting device (70) transmits energy into or out of the pressure vessel (12) through a wall portion (24) of the pressure vessel (12). The energy transmitting device (70) includes a first portion (72) outside the pressure vessel (12) and a second portion (74) inside the pressure vessel (12). One of the first and second portions (72, 74) of the energy transmitting device (70) converts the energy into electrical current. The second portion (74) of the energy transmitting device (70) is electrically connected with the device inside the pressure vessel (12). In one embodiment, the device inside the pressure vessel (12) is a squib (68) which is actuated by electrical current to cause inflation fluid to flow from the pressure vessel (12).

Inflator for inflating an air bag having magnetically coupled internal ignition

A firearm including a barrel having a combustion chamber for receiving propellant and at least one projectile, includes an electrically switched propellant igniting element disposed within the chamber for igniting propellant dispensed into the combustion chamber. A trigger switching assembly, electrically coupled to the igniting element, applies an electrical current pulse to the igniting element when the trigger assembly is operated in a firing mode, the pulse having a duration which causes the igniting element to ignite propellant dispensed into the combustion chamber.

Firearm having an electrically switched ignition system

An ammunition system for a rapid fire gun. The ammunition system includes a bullet (200) having a tip that is stored in a retracted position and during flight is deployed to create an aerodynamic shape. Another aspect of the ammunition system is that the bullet has a cylindrical body (199) having a first length in storage and a second longer length after ignition of the propellant.

Projectile for rapid fire gun

The device for firing ammunition has a combustion chamber (3) which accommodates several propellant charge bodies (11) containing a propellant charge (21) and an ignition means (35) for the ignition of the propellant charge (21). There is provided at the combustion chamber (3) a fixed primary coil (17) which receives an ignition signal, while in each propellant charge body (11) there is arranged a secondary coil (31) which is connected to the ignition means resistor (33) initiating the ignition means (35). The temporally variable magnetic field generated by the primary coil passes through the combustion chamber (3) and induces a current in the secondary coils (31) in each of the propellant charge bodies at the same time, so that the ignition means (35) of all the propellant charge bodies are activated simultaneously and all the propellant charges (21) ignite at once. Due to the simultaneous ignition of the propellant charge bodies, rapid firing sequences can be achieved.

Die Vorrichtung zum Verschiesen von Munition weist einen Verbrennungsraum (3) auf, der mehrere eine Treibladung (21) und ein Zundmittel (35) zum Zunden der Treibladung (21) enthaltende Treibladungskorper (11) aufnimmt. The apparatus for firing ammunition comprises a combustion chamber (3) which receives a plurality of containing a propellant charge (21) and an ignition means (35) for igniting the propellant charge (21) the propellant charge body (11). An dem Verbrennungsraum (3) ist eine ortsfeste ein Zundsignal empfangende Primarspule (17) vorgesehen, wahrend in jedem Treibladungskorper (11) eine Sekundarspule (31) angeordnet ist, die an einen das Anzundmittel (35) initiierenden Zundmittelwiderstand (33) angeschlossen ist. To the burning compartment (3) has a stationary, an ignition signal receiving primary coil (17) is provided, while in each propellent charge body (11) having a secondary coil (31) is arranged, which at one hand, the igniter (35) initiating Zundmittelwiderstand (33) is connected. Das von der Primarspule erzeugte sich zeitlich andernde Magnetfeld durchsetzt den Verbrennungsraum (3) und induziert in den Sekundarspulen (31) jedes Treibladungskorpers einen Strom, so das die Anzundmittel (35) samtlicher Treibladungskorper gleichzeitig aktiviert werden und alle Treibladungen (21) auf einmal zunden. The time-varying magnetic field of the primary coil generated itself passes through the combustion chamber (3) and induced in the secondary coils (31) of each propellent charge body a current, so that the means of ignition (35) of all the propellant charge bodies are activated simultaneously and all the propellant charges (21) ignite at once. Aufgrund der Simultanzundung der Treibladungskorper konnen schnelle Schusfolgen erzielt werden. Due to the simultaneous ignition of the propellant charge fast shot sequences can be obtained.
