Abstract: A decompression panel is releasably secured in a decompression opening of a partition structure by means of mounting elements that can release the panel in either a blow-in or a blow-out direction. A perimeter frame bridges the area at the perimeter of the panel and overlaps the edges of the panel and of the partition structure around the decompression opening. Respective pairs of mounting elements are arranged near the edge of the panel and the edge of the partition structure to releasably secure the perimeter frame to the partition structure and to the decompression panel. Each mounting element includes a bolt and a retaining device including two conical sleeves arranged one within the other. The bolt is screwed into the inner sleeve and the inner sleeve is releasably connected to the outer sleeve by frangible safety tabs, which break at a rated force to release the bolt and thereby free the decompression panel and allow it to be displaced out of the decompression opening.

Abstract: The present invention is directed to an optical proximity fuse for missiles with laser transmitters and optical receivers, whose optically bundled beam paths are oriented in such a way at a small angle to the direction of flight that they intersect in predetermined measuring segments, wherein the radiation reflected from objects in these measuring segments is utilized for deriving the firing pulse, wherein at least two laser transmitters oriented at angles different from each other and a common optical receiver are arranged at different points of the front side of the missile. The measuring segments where the transmitter beam paths intersect the receiver beam path lie at different distances from the missile and at differing side spacings from the longitudinal axis of the missile, wherein the measuring segment lying closer to the missile corresponds to the predetermined target segment. The laser transmitters are modulated at identification response codes differing from each other.

Abstract: The invention relates to a gasoline engine having a catalyst for reducing the emission pollutants, with an oxygen absorption device located in the exhaust line upstream of the catalyst. According to the invention, the gasoline engine is operated in a first operating range with a lean air/fuel ratio (.lambda.), and oxygen is removed from the exhaust by the absorption device. In a second operating range, the gasoline engine is operated at .lambda.=1, and the absorption device is bypassed or deactivated. In the case of a gasoline engine with a Denox catalyst the gasoline engine is operated constantly with a lean air/fuel ratio, with the active surface of the Denox catalyst being "depoisoned" temporarily by activating the oxygen absorption device.

Abstract: An intercept device for flying objects is formed of a lightweight, small-volume, packable structure made of a tear-resistant, pliable material, which can be stretched to a large, two-dimensional or three-dimensional expansion by means of a deployment device.

To end the intercept procedure, elements are integrated into the structure, which consist of material that can be destroyed from outside by means of high-energy beams and/or chemical reagents, or that destroys itself, or the structure as a whole consists of such material.

Abstract: A separation wall for dividing a cabin space inside a passenger aircraft is constructed of two wall elements rigidly connected to each other in an overlap area. The transition between the overlap area and a respective wall portion of the corresponding wall element is formed by an off-set (27B, 28B; 31B, 32B).

For this purpose the respective lateral edge tapers or curves upwardly to accommodate the aisle or the curvature of the body wall. The overlap area provides an improved strength and wall extensions (28D or 31D) form a space (19) for storage of items or mounting of equipment.

Abstract: A process for stripping of used parts or reject parts, in particular of polycarbonate (PC) or of a polycarbonate blend, preferably with polybutylene terephthalate (PBT/PC), for the purpose of recycling the plastic. In this process the plastics parts are first mechanically comminuted to a pourable size and then are circulated together with anhydrous alkalified diethylene glycol or propylene glycol in a mass with mutual abrasion of the plastics chips at elevated temperatures of at least 50.degree. C., preferably from 80.degree. to 100.degree. C., until complete removal of the paint. Thereafter the stripped plastics chips are separated from the stripping agent, flushed and then dried. The quantity of glycol added corresponds to from 1 to 10% of the volume of the mass to be treated, so that the circulated parts are only wetted by the glycol, but with stripping agent being circulated continuously through the treatment space of the mass from a relatively large reservoir.
