Patent number: 7836812Abstract: A propellant charge feed or supply system for automatic introduction of modular propellant charges into the weapon tube of a heavy weapon having a breech assembly and a propellant charge chamber in front of the breech assembly. An oblong propellant charge feed tray is pivotable into position behind the weapon tube such that propellant charges disposed on the propellant charge feed tray are disposed coaxial relative to the axis of the bore of the weapon tube. A providing device is adapted during a feed stroke to move the propellant feed tray into the breech assembly up to the propellant charge chamber. An introduction device is adapted during an introduction stroke to move the propellant charges from the feed tray into the propellant charge feed tray.Type: GrantFiled: June 26, 2006Date of Patent: November 23, 2010Assignee: Krauss-Maffei Wegmann GmbH & Co.

Patent number: 7475626Abstract: A device for feeding propellant charges to a heavy weapon, comprising a fixed propellant charge magazine having guides for receiving propellant charge modules such that their longitudinal axes extend horizontally. The guides are disposed parallel to one another and in horizontal planes above one another. A propellant charge feed mechanism for removing propellant charges from the magazine and transferring them to a propellant charge transfer arm includes an automatic feed mechanism disposed adjacent to the magazine and having a propellant charge chain driven in a vertical plane and provided with receiving elements for propellant charge modules. A portioning unit is disposed at the removal position at the upper end of the chain and axially relative to a respectively uppermost receiving element. The portioning unit has a mechanism for transferring and joining propellant charge modules. A mechanism is provided for transferring joined modules from the portioning unit to a propellant charge feed tray.Type: GrantFiled: May 14, 2005Date of Patent: January 13, 2009Assignee: Krauss-Maffei Wegmann GmbH & Co.

Patent number: 6840622Abstract: The invention relates to a method and system for determining the topography for reaction signals of an eye. The reaction signals of cyclic luminous excitations are simultaneously measured on partial surfaces of the retina by using, for each partial surface, another integer number of oscillations in a predetermined time segment. These oscillations are derived from a clock rate. In the time segment, a smaller number of oscillations occur by prolonging a clock pulse by an appointed interval, and a greater number of oscillations occur by shortening the clock pulse by an appointed interval. The cumulative signal recorded on the patient contains the sum of the reaction signals and is digitized in an amplified and filtered manner with the clock pulse for generating the oscillations. The reaction signals of the individual partial surfaces are recovered by cyclic summation.Type: GrantFiled: December 11, 2000Date of Patent: January 11, 2005Assignee: Medizin & Service GmbHInventors: Johanna Jutta Kutschbach, Jens Grünewald, Ernst Kutschbach

Publication number: 20010015126Abstract: A multiple-barrel mortar assembly for launching grenades and similar items and mounted on the side of a combat vehicle. Several modules that can rotate in azimuth are mounted in a mount. Each mount is provided with a barrel accommodated in a block. Each barrel extends at a prescribed acute angle to the base of the block. The angle establishes the assembly's elevation. Each block is secured in a frame. The frame can rotate around an axis perpendicular to the base of the block. A drive mechanism can rotate all the frames simultaneously through a prescribed range of angles around the axis.Type: ApplicationFiled: February 9, 2001Publication date: August 23, 2001Inventor: Jens Grunewald
