Abstract: To increase the fuel tank capacity particularly in a tractor, the tank (2') is provided with a cavity (12) for housing the engine air filter (3) within the overall outline of the tank, the filter (3) being fixed in the cavity (12) in such a manner as to leave the air intake port (10) and delivery port (11) of the filter free. The cavity (12) can pass through the tank (2') between its side walls (13, 14) and the wall of the cavity (12) can form a wall portion of the filter, which can consist simply of two endpieces (8', 9') fixed to the ends of the cavity (12) and housing the filter cartridge (6). The reduction in tank volume by virtue of the filter housing is compensated by the greater extension of the tank to the side of and/or above the engine because of the absence of the conventional filter.

Abstract: Procédé et système de régulation de commande de processus par réseau neuronal informatisé permettant d'éliminer un opérateur humain de la commande en temps réel du processus. Cette invention fonctionne suivant trois modes qui sont: apprentissage, fonctionnement (prédiction), et nouvel apprentissage. En mode apprentissage, les données d'entrée d'apprentissage sont produites par le réglage de commande effectué par l'opérateur humain sur le processus. Le réseau neuronal de cette invention apprend en générant des données de sortie utilisant les données d'entrée pour la prédiction. Les données de sortie sont comparées aux données d'entrée d'apprentissage pour générer des données d'erreurs qui sont utilisées pour ajuster le ou les facteurs de pondération du réseau neuronal. Lorsque les données d'erreurs sont inférieures à un critère préselectionné, l'apprentissage est terminé. En mode de fonctionnement, le réseau neuronal de cette invention fournit des données de sortie basées sur les prédictions en utilisant les données d'entrée. Les données de sortie sont utilisées pour commander un état du processus par l'intermédiaire d'un actionneur. En mode de nouvel apprentissage, on détermine les données de nouvel apprentissage en surveillant les actions supplémentaires de l'opérateur humain. Les données de nouvel apprentissage sont utilisées par le réseau neuronal pour ajuster le ou les facteurs de pondération du réseau neuronal.

Title: Process and device for closing an aperture in a tubular container.
Inventor: KULLBERG WILHELM JR
IPC: B65D5/08
Filed: 1991-11-16
Abstract: A process and a device for closing an aperture in a tubular container designed especially for fluids and consisting of paper or cardboard with a sealing coating on at least one side, involve closing the upper container aperture by folding the four container sides at the top over one another and securing them. To allow the closure to be easily opened by pulling up one side of the closure to form a pouring lip and to sealingly secure the four folded container sides, a foil-like sealing component is adhesively secured to the inner surface of the front of the container after folding of the sides. Thus, in particular, the free folded edges of the container sides are sealed and firmly secured to the bordering regions of the adjacent sides without the surfaces folded on top of one another being stuck together. When the container is opened by pulling up the pouring lip side of the closure, the sealing component is easily separated along the folded sides to which the pulled-up side is attached, thus facilitating opening the closure.

Abstract: In the adsorptive elimination of contaminants from water, a procedure is followed so that at least a majority of the solid, fine-grained adsorbents experience a size reduction during the adsorption process, in order thus to create fresh surfaces, which are brought into contact with water immediately on their formation and are thus brought into contact with the pollutants contained therein. As a result, a relatively large loading of the fine-grained adsorbents is achieved. This has a favourable effect on the loading itself and on the adsorption isotherms. The adsorptive purification can additionally be combined with biological purification. <IMAGE>
