Retrieving the data of the entry from the database for recycling the container.

Abstract: The invention relates to a method for coding a dimensionally stable packaging container or an associated component made of a plastics-based and/or paper-based material composition, the packaging container being suitable for storing consumer goods such as food, washing agents, etc., wherein, during a shape-forming process for forming the three-dimensional packaging container or the associated component by means of a shaping tool mold, at least one outer and/or inner side undergoes, in at least one position, a shape-changing treatment acting on its first surface in order to produce at least one three-dimensional code.

Abstract: A flexible press cover which has an additional strengthening element in at least one of its two end regions. As a result, in the end region, the tensile strength and the tensile rigidity in the circumferential direction are increased with respect to that hitherto known in such a way that it is no longer necessary to clamp the press cover end region in between two components. Instead, the press cover according to the present invention is suitable to be fixed to the outer circumferential surface of a rotatable supporting element belonging to the cover carrying disk without the aid of an outer ring, a clamping band, clamping filament or the like. In the most beneficial case, the arrangement for fixing the press cover to the aforementioned supporting element is completely free of any kind of fixing elements which would be associated with the cover outer surface.

Abstract: A method for the on the whole minimum-fuel, computer-assisted control of an optionally determined number of thrusters, arranged as desired on a spacecraft, is to be specified, which method solves this linear optimization problem within the shortest possible time by reducing the computation expenditure. The method depends on the dual simplex algorithm and a suitably provided dual permissible start table. The dual permissible start table is set up on the basis of a previously computed optimum table and the transformation of the actual forces-moments vector belonging to the selected start table. Specific processing steps in the dual simplex algorithm are either not needed at all or are substituted with processing steps that require considerably less computation expenditure. Finally, a reduced table is used in place of the simplex table.

Abstract: In optimization of combinatory optimization problems, it is possible to perform deterministic as well as more or less randomized searches. A new allocation matrix is generated, based on a more or less coincidentally selected, but valid allocation matrix. A check is made thereafter whether it constitutes a better solution than the old allocation matrix. If this is the case, this matrix is used as the new starting point for the further search. If this is not the case, the old allocation matrix is kept as the starting point for the further search. This process is continued until the time made available for the solution has expired, or until it is determined by the method itself that no better solution can be found in the course of the instantaneously realized search.

Abstract: An extended nip press for the dewatering of a fiber web has an endless flexible press element, like a press jacket or press belt. A press shoe has a concave slide surface for the flexible press element, and the slide surface is adapted to the curve of a backing roll. The shoe is displaceable toward the backing roll in order to press the pressing element against it. A stationary shoe bed, which is detachably connected to a stationary support, has a depression which is provided with a packing and receives the press shoe to form a pressure chamber so that the shoe bed and the press shoe form a cylinder-piston unit. The press shoe is coupled to the shoe bed by means of at least one connecting element. The connecting element is spring biased with respect to the shoe bed and may itself be flexible or be flexibly moved to permit the radial displacement as well as the tilting of the press shoe relative to the shoe bed.

Abstract: A press roll for a web includes a support body which is either stationary or rotatable and a press shell which is rotatable over the support body and against a mating roll. A respective shell support element or disc is disposed axially outward of both ends of the support body and the support element has an axially outward, face side. The flexible, liquid impervious endless belt press shell has lateral edge zones. Each edge zone has a respective plurality of outwardly projecting tongues and has cutouts between neighboring tongues. The edge zone is turned radially inward and its tongues are each respectively mounted on a holding element projecting from the face side of the shell support element. Centering elements also ono the face side of the shell support element are placed each for extending into and contacting the base of the cutouts between neighboring tongues for positioning the tongues.

Abstract: A long nip press roll for removing water from a traveling fiber web. A rigid support beam has at least one recess in its periphery for receiving a radially movable hydraulically operated press shoe. A flexible tubular press shell is wrapped around the support beam and the press shoe. The concave outer surface of the press shoe presses the press shell against a backing roll for pressing upon a fiber web against a felt belt passing through the nip. The press shell has a smooth outer surface in contact with the web. At its outlet side from the press nip, the press shoe has a convexly curved guide surface over which the press shell and the paper web travel together and that guide surface is also wrapped for a distance by the felt belt. This separates the web from the felt belt and the web travels around on the press shell. A ledge inside the press shell and/or a removal roll at the outside of the press shell separate the web from the outside of the press shell.

Abstract: A long nip press roll includes a stationary support member and a flexible, tubular, inflatable press shell which is supported to rotate around the support member by axially separated support discs rotatable around the support member. A radially displaceable press shoe is supported on the support member for pressing outward against the press shell against a counter roll in the press plane. To enable the press roll to be used in a press where it is disposed either beneath or above the counter roll, all of the internal lines in the support member, e.g. those for the supply and discharge of pressure oil, lubricant and cooling oil and press shell pressurizing air, include two sets of coupling for coupling them to external lines, a respective set of the couplings being located at each axial end of the press roll. During assembly, one of the sets of couplings at one end is connected to external lines, and the other set of couplings is closed.
