  • Patent number: 7239843
    Abstract: The participants of a friendly communication system use so-called time windows in the interference pattern for the communication and transmission among each other. These time windows are preset ahead of time in the communication system by the jamming transmitter or are created and/or adapted individually and short-term with the aid of software programs. Since only the communication-system participants can recognize and/or detect these time windows, they are the only ones that can receive and/or transmit corresponding information during these time windows. The information is compressed in the known manner, such that it can be transmitted and received completely during the brief time window provided. The information can then be decompressed and read during the time of interference in the known manner.

  • Patent number: 7178443
    Abstract: A wedge-type breechblock is provided for a weapon having a barrel that recoils relative to a cradle, the barrel having a bore with an axis, and a breech plate. The breechblock includes a closing wedge for arranging in the breech plate such that the closing wedge can be displaced transverse to the axis of the bore. A pin-type carrier, through a control lever and a breech mechanism shaft, activates the closing wedge. An ascending curved track is located on a guiding device, and guides the pin-type carrier during a counter-recoil motion of the barrel from an intake region to a highest point, so that the control lever is pivoted during the counter-recoil motion of the barrel and the breech mechanism shaft is turned to move the closing wedge to an opened position.

  • Patent number: 7171886
    Abstract: To seal a pipe mortar, a sealing element (3, 6) is inserted between the pipe (1) and the base (2), with the element elastically balancing out the axial relative movements between the pipe (1) and the base (2). The sealing element (3) is preferably prestressed, with the gas pressure supporting the sealing effect. The sealing element (3, 6) can be a U-shaped or L-shaped steel ring. In the U-shaped sealing element (3), the legs (3.1) are axially prestressed to the extent that the sealing ring (3) and the pipe (1) or the base (2) are pressed together to produce an adequate seal. In the L-shaped sealing element (6), the inside leg (6.1) produces the gas-tight connection when the pipe (1) and the base (2) are screwed together. A sealing lips (6.2) of the sealing ring (6) elastically absorbs changes in length between the pipe and the base that occur during firing.

  • Publication number: 20050018261
    Abstract: The invention relates to a method for transferring the wave front of primary light pulses with a specifiable first pulse duration and/or energy to secondary light pulses with a specifiable second pulse duration and/or energy. For an easy realization of a wave front transformation of this type, it is suggested according to the invention to store respectively in a first time segment the wave fronts of the primary light pulses with the aid of reference light pulses as spatial hologram in a holographic memory. In a following second time interval, this stored, spatial hologram is then read out with the aid of reconstruction light pulses, having the second pulse duration and energy, wherein the reconstruction light pulses for reading out the hologram have the same wavelength and wave front as the reference light pulses.

  • Patent number: 6827206
    Abstract: A packaging container is provided for a large-caliber cartridge having a thin-walled cartridge case and a projectile, whose projectile head projects out of the front of and is connected to the cartridge case. The packaging container has an outer container and an inner container, which receives the cartridge. To secure the projectile of the cartridge inside the packaging container, with respect to a possible displacement of the projectile toward the rear end of the container, the projectile head of the cartridge is disposed in the inner container in a frictional lockup. For this purpose, the inner container has a one-piece projectile-head shaped receptacle at the front, to which a first half-shell that partially surrounds the cartridge case is connected, and a second half-shell, that is hinged to the first half-shell and can be secured to it.

  • Patent number: 6819298
    Abstract: A high-power microwave antenna in which, in order to radiate a pulse (8), the antennas (4) of the high power microwave are actuated by a pulse-generating source (3) and are embodied normally as wire antennas, horn antennas or the like. In particular for HPM active systems (1) to be conveyed, the antenna aperture of the antenna (4) is limited by the geometric edge dimensions of a carrier system (2) for the HPM active system (1), which further leads to a reduction in the efficiency of the antenna (4). According to the present invention, the antenna (4) is integrated into an airbag (5) that is inflated for operational use and thereby simulate the antenna (4). The antenna airbag (5) is inflated near a target (100) onto which at least one pulse (8) must be radiated.

  • Patent number: 6815701
    Abstract: A method and a device for measuring wear on the internal surfaces (12) of barrels (1), in particular weapon barrels. For a very precise determination of the wear on the internal surfaces (12) of barrels (1), a non-contacting scanning of the internal surface (12) of the respective barrel (1) to be checked is carried out with a light-spot triangulation sensor (6), to determine the respective distance between the internal surface (12) and the barrel axis (7) for selected sensor positions. The contour of the internal surface (12) of the respective barrel (1) is then determined from the detected distance changes. It has proven advantageous if the measured distance values are displayed on a monitor (23) in the form of a C-image, wherein different distance ranges are characterized with different colors, so that faulty surface areas can immediately be recognized optically.
