Abstract: A device for transferring ammunition from a magazine to a transfer arm of an adjustable weapon rotatable about a trunnion. The transfer arm is movable together with the weapon and tilts up to a maximum predetermined angle (.beta.') during azimuth adjustment of the weapon. Two angle compensating elements are rotatable relative to one another about a common axis in planes that are inclined by half the predetermined angle (.beta.'/2) and are operatively disposed adjacent the magazine. A planar turntable is rotatably mounted on the two angle compensating elements for rotation relative thereto about the common axis. The plane of the planar turntable is adjusted by the two angle compensating elements. An ammunition receiving and pivoting device is supported on the turntable for receiving ammunition from the magazine and pivoting the ammunition so that the ammunition can be received by the transfer arm of the weapon.

In order to remove heat, the side (14) of the circuit board (10) which is not provided with the circuit components can be directly wetted with coolant.

Abstract: A fin stabilized ballistic projectile comprises a projectile body having a plurality of stabilizing fins and an ejectable projectile tip detachably attached to the front of the projectile body. An ejection mechanism is operatively disposed for ejecting the projectile tip. A sensor is disposed in the projectile tip for scanning a target area. A warhead is disposed at the front of the projectile body behind the projectile tip and includes a curved fragmentation plate for discharging fragments at a target, with the fragmentation plate being openly exposed when the projectile tip is ejected, and an explosive charge disposed behind the fragmentation plate.

Abstract: A warhead having hollow charge, such as a bomblet as well as a large caliber armor-piercing projectile has an improved detonation wave guide arrangement which preferably produces a high pyrophoric effect at target impact.The detonation wave guide itself is made of an incendiary-active (flamable) material, whereby a strong exothermal reaction is released by shock waves at target impact in the binding substances which form the wave guide. By exclusively initiating this exothermal reaction and incendiary effect by means of shock waves a rapid and simple introduction of the reaction in a few microseconds is achieved. The binding substance consists of metal particles and gases embedded in matrix. These metal particles have a high combustion enthalpy and the matrix is made of an organic polymer.

Abstract: A subcaliber projectile assembly includes a subcaliber projectile; a supporting member engaging the circumferential surface of the projectile; a guide band supported on the supporting member; and a propelling cage supported on the circumferential surface rearwardly of the guide band. The propelling cage is formed of a plurality of segments mounted in a circular array and each segment is a stamped sheet metal component. Each segment has a bottom portion shaped as a circular cylinder section having opposite longitudinal edges and an underside being in engagement with the circumferential surface of the projectile. Each segment further has two longitudinal ribs connected to the bottom portion along the longitudinal edges and rising radially from the bottom portion. Each segment also has a transverse wall portion extending transversely to the bottom portion and the ribs and interconnecting the ribs with one another at a front-side longitudinal end of the segment.

Abstract: An ammunition container (1) for large caliber ammunition (2) includes two shells (5, 6) that are arranged parallel to the ammunition, with one shell (5) being fixed and the other shell (6) being movable. A rotatable control lever (7, 7') is mounted at least one end (10, 11) of the ammunition container (1), the control lever having a pivot axis that coincides with the longitudinal axis (12) of the ammunition container (1). The movable shell (6) and the control lever (7, 7') are connected with one another by way of a releasable holding mechanism (9) so that, upon pivoting of the control lever (7, 7') from an open position to a closed position, the movable shell (6) also rotates about the longitudinal axis (12) of the ammunition container. In addition, the control lever (7, 7') has a cam (70) on which the movable shell (6) is mounted so as to be freely rotatable.

Abstract: A device is provided for reducing the rate of rotation of a spinning submunition unit having a tail end provided with a deployable braking device, from a time after the submunition unit is ejected from a spin stabilized carrier projectile until the braking device is deployed. The device includes a plurality of bands arranged to form a star-shaped symmetrical band structure for placement around the braking device. Each of the bands has a free end provided with a wind pocket.

Abstract: In known droppable mines it customarily becomes necessary, because of the consistency and slope of the ground, to right the mine into a position favorable for its action, with such a position being fixable, if possible, for the entire duration of deployment independently of extraneous influences.Since in the past such fixing was realized in the known mines only in a complicated and unsatisfactory manner, the mine (10) according to the invention includes a sack (18) which is arranged below a righting balloon (16) and is filled with a hardenable foam. In this way, the stability of the mine (10) is decisively improved. Due to the underside (22) of the sack (18) being kept permeable, the foam is also able to escape into a zone (34) between the ground (12) and the sack (18) and cause the mine (10) to adhere to the ground (12) in its position.

Abstract: A deceleration device for a submunition unit includes a cartridge releasably attached to the submunition unit. A releasable package including at least one pocket is disposed in the cartridge and is connected to the cartridge by a packaging line. An auxiliary parachute and a rotation parachute are disposed in the cartridge, with at least the rotation parachute being accommodated in the at least one pocket of the releasable package and the auxiliary parachute being disposed in a pocket separate from the at least one pocket. The auxiliary parachute is connected to the cartridge and the rotation parachute is connected to the submunition unit. A deployment mechanism causes the auxiliary parachute to be deployed in advance of the rotation parachute after the cartridge is released from the submunition unit and the rotation parachute to be deployed after the cartridge is decelerated by the auxiliary parachute for decelerating the submunition unit.

Abstract: A deceleration element is provided for attachment to a tail end of a submunition unit for deployment when the submunition unit is ejected from a spin stabilized carrier projectile for reducing velocity and spin of the submunition unit. The deceleration element includes two approximately circular, air-tight, planar textile fabric layers of essentially the same size having a diameter exceeding the diameter of the submunition unit and circumferentially sewn together to form an inflatable interior between the two fabric layers. The fabric layer disposed closest to the tail end of the submunition unit is clamped by fasteners to the tail end of the submunition unit and has a front side facing the tail end of the submunition unit for encountering air when the deceleration unit is deployed. At least four air capture pockets are disposed at the front side of the one fabric layer and are distributed at regular intervals in a circumferential direction.

Abstract: A deceleration device for a submunition unit ejectable from a spin stabilized carrier projectile includes a deployable deceleration element. The deceleration element is packaged in textile package including an essentially circular disc, at least three straps connected and arranged radially to the disc, with each strap having a free end and provided with a loop and a closing line received through the loops for pulling the loops together to close the package about the deceleration element. An activation line is connected to the closing line and held by the textile package for releasing the closing line for allowing the package to open for deployment of the deceleration element after the activation line is released from the package by being stretched in a controlled manner.

Abstract: A wall of, for example, a bombshelter or armored vehicle, is provided with an inner and outer armor spaced from each other. This armor protection is designed to provide a deflection, respectively destruction of an impacting projectile as soon as the projectile nose has penetrated the outer armor. The arrangement is designed to permit only a relative minor destruction of the outer armor in the impacted region, so that those regions adjoining the impacted region maintain their protective structural integrity.This object is achieved in that in the partial chambers which are divided by transverse walls defining closed intermediate chambers between both armors there is disposed a material insert which explodes or bursts as a result of the penetration of the projectile, for example, a material insert consisting of an explosive, glass or ceramic material. The outer armor consists of plates which are overlappingly arranged at one of the adjoining sides and which swing outwardly.

Abstract: A subcaliber projectile including a segmented discardable propelling cage sabot which encloses at least a portion of the projectile body and has a common form-locking zone for the transfer of acceleration forces from the propelling cage to the projectile body. The form-locking zone has mating annular grooves and counter grooves on the exterior surface of the projectile body and on the interior surface of the propelling cage, and is subdivided into several form-locking zone regions in which the annular grooves have a different groove spacing that is adapted to the locally occurring shear stresses. These measures enhance simplification of the manufacturing process and result in an improvement of the release of the propelling cage sabot from the projectile body and in an increase in the target impact velocity of the projectile body.

Abstract: A rotary parachute includes a canopy having an apex and comprised of triangular, sewn-together fabric segments each having a base edge along an outer circumference of the canopy, a tip opposite the base edge and longitudinal edges on either side of said tip with seams connecting together the adjacent longitudinal edges of adjacent segments and rotation slits existing in regions of the respective seams. The tip of each segment is offset laterally from the apex of the canopy to form an apex opening in the canopy having a shape of a regular polygon and the base edges are offset from one another so that each segment has a circumferentially projecting tip.

Abstract: A screen printing machine for imprinting hybrid circuit boards with thick-film pastes of the type including a horizontally movable printing table (12) and a vertically raisable frame (16), wherein a compressed air cleaner (2) is attached to the frontal or end surface (18) of the frame (16). This compressed air cleaner (22) is actuated by means of switches (28, 30), preferably proximity switches, as a function of the side to side movement of the printing table (12) and thus permits an automatized cleaning process for the hybrid circuit board (14).

Abstract: A submunition unit provided with a rotary parachute (3) as the sole parachute. The parachute, after release, initially is unable to be fully deployed due to reef loops (16) provided on the rigging lines (15) and held by a releasable holding device arrangement (4, 5, 6) and therefore acts as a deceleration and stabilization parachute at high flight velocities. The reef loops (16) are released after a predetermined period of time to permit the rigging lines (15) to fully extend and parachute (3) to become fully deployed or opened.
