Abstract: Packaging container for beer or other pressurized filled goods are conventionally manufactured in the form of metal cans. Attempts to use less expensive material, such as paper, has thus far been unsuccessful due to the material's lack of strength and difficulties in sealing gable tops and the jacket.This invention provides a packaging container and a method of manufacturing the same that eliminates the aforementioned difficulties in that the jacket (1) is made of several material layers (4) that are not sealed together except for the gable and the longitudinal seals. The gable is additionally fastened via the refolding of the unsealed material layers and subsequent sealing, which results in the different layers of the packaging container being evenly loaded and thereby able to absorb and distribute great stresses without damage.<IMAGE>

Abstract: A tube is connected via a feed control to a fluid tank. The tube is also connected to a level sensor which during the filling process automatically activates the feed control so that when a required level of fluid is reached in the cell, fluid flow is interrupted. - The sensor comprises a second tube running parallel to the first one, and with a lower aperture which during the filling process is positioned at the required level in the cell. The tube is connected to a gas source via a pipe on which a pressure gauge is connected. This gauge on increase of pressure caused by the electrolyte level increasing to cover the lower aperture of the sensor tube, activates the feed control to terminate filling.

Abstract: The novel dialkanoyl, diaroyl or alkanoyl-aroyl L-tartaric acid-O-monoesters of 3-morpholino-4-(3'-tert-butylamino-2'-hydroxypropoxy)-1,2,5-thiadiazol e correspond to the formula <IMAGE> (R = the alkyl or aryl group). They are intermediates in the preparation of S-3-morpholino-4-(3'-tert-butylamino-2'-hydroxypropoxy)-1,2,5-thiadiaz ole, i.e. of S-timolol, which has useful  beta -blocking activity, as well as of its acid addition salts. The said L-tartaric acid-O-monoesters are prepared from the corresponding L-tartaric anhydride and R,S-timolol, and their resolution is carried out by crystallising the racemic ester from an alcohol or from a mixture of alcohol and water in a pH range from 7 to 2, resulting in the isolation of the L-tartaric acid-O-monoester of S-timolol in optically pure form, from which ester S-timolol is liberated by acid hydrolysis and can be converted to the desired acid salt.

Abstract: The invention relates to a method for the control and/or monitoring of the drying process of a web (W) taking place on the Yankee cylinder, the air distribution system of the Yankee cylinder being divided, expediently into three parts, and a computer being used in the method for the control of the process. In the method, a process model is applied which is put forward on the basis of trial runs, on-line measurements and/or drying theory of the process to be controlled or its equivalent. Grade-specific desired value parameters corresponding to the web grade to be run are input from a so-called grade card file or recipe card file. New output values are input into the simulation programme at specific time intervals, measured values of the process parameters obtained from various measuring transmitters of the drying process and, possibly, web samples and coating samples analysed in the laboratory, are used for this. For the purpose of minimising the inaccuracies of the process model, an adaptive process model is applied in the method, for which purpose one specific or several specific parameters in the process are left as variables which are adapted in the correct direction, based on the new output values of the process, in such a way that the process model, as a result, gives values for the measured parameters corresponding to the measured results.
