Abstract: A hollow charge construction comprises a housing which has an interior chamber with an explosive material in the chamber which is covered on at least one side by a hollow charge liner. A range spacer for the hollow charge extends ahead of the charge and serves to time its firing and/or detonation setting at a specified range ahead of the target, and it comprises a material which is destructible by impact dispersion to piece parts.

Abstract: Shear transfer elements can be formed by winding or weaving unidirectional fibers on a support structure. In a winding operation the support structure consists of two intersecting planes of winding mandrels with the planes arranged in angularly spaced relation. Each plane has two pair of mandrels with the mandrels in each pair located on the opposite sides of the line of intersection between the two planes. After the fibers are wound on the mandrels, each mandrel is axially disposed in the opposite direction relative to the other mandrel in the pair and also to the adjacent mandrel in the other pair in the same plane. Next, the fibers are pressed to form the shear transfer element. In a weaving operation, the support structure consists of a pair of pivotally interconnected frames. The fibers are woven onto holders on the sides of each frame extending parallel to the pivot axis of the frames.

Abstract: The analog output signals of a photoelectric image converter or transducer are passed through an analog-to-digital converter and then corrected to take various irregularities of the optical sensor elements of the transducer into account. A reference signal and a dark signal are subtracted from the individual image point signals. The difference is then multiplied by a factor representing the slope of the characteristic response curve of the respective optical sensor element. The so corrected signal may be used for further processing or it may be subjected to a further correction operation.

Abstract: A method of stopping out interfering radiators in a device for optically viewing the radiation produced by a missile through a lens aperture and for steering the missile as a result of the radiation viewed, comprising setting the opening of the lens aperture in a wide opening position during the launch of the missile and viewing the radiation through the opening set, determining the off position of the missile relative to the optical axis of the device by means of a modulator disc disposed in the image plane of the device and a radiation detector which is disposed behind the image plane on which the image of the entrance pupil of the device is formed and, after the off position is determined, reducing the image field of the lens of the device to an image area immediately surrounding the missile.

Abstract: The corner of a structural member has first, second, third and fourth surfaces which converge to form the corner with first, second and third layers of fiber reinforced material successively applied to the corner surfaces to form the walls of the corner. The first layer of fiber reinforced material completely covers the first and second surfaces and partially covers the third and fourth surfaces. The second layer completely covers the second and fourth surfaces and that part of the third surface which remained uncovered by the first layer, and the third layer completely covers the first and third surfaces and that part of the fourth surface which remained uncovered by the first layer. The three layers arranged in this manner therefore produces corner walls having a thickness corresponding to two of the layers. The fibers in the two layers forming the walls extend in directions transverse to each other and form patterns different from each other.

Abstract: The present invention relates to an electrical connector designed for use inside a tube such as an ejector tube for the expulsion of bodies from the tube, whereby the electrical connector is ejected from the tube together with the respective body, such as a mine. As soon as the body leaves the tube, the connector automatically separates itself from the ejected body and falls apart. For this purpose the components of the electrical connector are so shaped that they cooperate for making electrical contact only inside the tube.
