Inventor: CARREAU JEAN-CLAUDE
IPC: B01J20/14
Filed: 1999-06-15
Abstract: The invention mainly concerns a method for regenerating used infusorial earth, said infusorial earth being used as filtering auxiliary and being retained in a filter chamber (1), said method comprising a step which consists in introducing an alkaline solution inside the filter chamber, while contacting said solution with the infusorial earth to be regenerated. The invention is characterised in that said method is followed by a step which consists in recuperating, outside the filter chamber, regenerated infusorial earth for reuse when subsequently filtering beer, as filtering auxiliary, said regenerated infusorial earth being introduced in the filter chamber in the form of a mixture with the beer to be filtered.

Title: Appareil servant a desactiver des micro-organismes
Inventor: MELLBIN HAKAN
IPC: A23L3/26
Filed: 1997-09-11
Abstract: L'invention concerne des procédés et des appareils utiles pour la conservation de produits alimentaires, mise en oeuvre au moyen d'une désactivation de micro-organismes et d'enzymes par l'application d'impulsions de lumière polychromatique à large spectre de courte durée et de forte intensité à des surfaces de matières de conditionnement. Dans certains modes de réalisation, on emploie une photodiode pour détecter l'intensité de la lumière, et un circuit de commande pour régler la puissance fournie à une lampe-éclair si l'intensité de lumière nécessite un réglage. Dans certains modes de réalisation, un verre extérieur de sécurité est utilisé pour protéger les lampes-éclair. Le verre extérieur de sécurité peut comporter des matières de revêtement à des extrémités de celui-ci. De plus, plusieurs variations de géométries d'ensemble lampe contiennent des tubes de matières de conditionnement de faible diamètre; celles-ci utilisent par exemple un tuyau de remplissage qui présente une première et une deuxième parties décalées comportant au milieu une zone de transition; ou n'emploient pas de chemises d'eau, mais un verre extérieur de sécurité pour contenir l'eau lorsqu'elle passe au-dessus des lampes-éclair. Dans un autre mode de réalisation supplémentaire, un dispositif porte-lampe comporte un cylindre support présentant un premier rebord qui, en coopération avec un cylindre de compression, permet de comprimer le premier joint torique à l'intérieur de la lampe. Dans un autre mode de réalisation encore, un dispositif porte-lampe est placé dans un réceptacle, dans lequel on insère une électrode d'une lampe en U. Le dispositif porte-lampe permet à une partie proximale de se déplacer par rapport à une partie distale de celui-ci. Dans un autre mode de réalisation enfin, un guide de lumière est placé de façon recevoir de la lumière émise par une lampe-éclair linéaire, et la transmettre dans une coupe de matière de conditionnement.

Inventor: GERBERICH H ROBERT
IPC: B01D3/36
Filed: 2000-06-06
Abstract: Gamma-Butyrolactone (GBL) is recovered from a mixture containing GBL and other heavy organics by a process of azeotropic distillation in the presence of a C8-C10 hydrocarbon as an azeotroping agent, wherein an azeotrope of GBL and the hydrocarbon is obtained as a distillate, which forms immiscible GBL-rich and hydrocarbon-rich phases, and the hydrocarbon-rich phase is decanted or isolated from the GBL-rich phase. By this process GBL can be efficiently separated from a large proportion of various compounds having boiling points close to that of GBL, e.g., the methyl-.gamma.-butyrolactones (MeGBL's).

Title: Actuating arrangement with interlock to prevent unintended actuation when in a non-operating position
Inventor: GUIET LIONEL
IPC: G05G5/28
Filed: 2000-07-07
Abstract: An actuating arrangement (14) for a front end loader or the like is provided with a locking bar (52), an adjustable carrier (46) and an interlock (44).

Filed: 1999-01-11
Abstract: L'invention concerne une gaine protectrice (10) destinée à un substrat allongé tel qu'un faisceau de câbles, des tuyaux ou analogues. Cette gaine consiste en un corps (11) en matériau élastique pourvu de cannelures sensiblement circonférentielles (12, 13) et d'une paroi latérale fendue sur sa longueur (25) de manière à permettre l'installation de la gaine sur les substrats. Les côtés de la fente sont définis par des bords (21, 22) de la paroi cannelée du corps poussés l'un vers l'autre et contigus pour permettre la fermeture de la fente. Un élément de fixation (30) sous la forme de bandes à fermeture auto-agrippante complémentaires (14, 15) est placé sur les bords contigus (21, 22) de la fente, de manière que les boucles et les crochets de la bande à fermeture auto-agrippante entrent en prise lorsque l'on ferme la fente. La bande à fermeture auto-agrippante protège les doigts du travailleur lors de l'ouverture de la fente en vue de l'installation de l'article tubulaire, et empêche tout mouvement relatif des bords de la fente provoqué par des efforts de rotation et de torsion, éliminant ainsi le bruit indésirable lors de l'utilisation, et évitant de devoir fermer l'installation avec un ruban.

IPC: G01N21/47
Filed: 2000-10-19
Abstract: An optical paper sorting system uses diffuse reflectance to identify a sheet of paper, conveyed on a conveyor, as either white or groundwood grade. A  light source illuminates a sheet of paper and an optical collection system collects and filters the light diffusely reflected from the sheet of paper. The reflected light strikes a detector which produces a photoelectric current proportional to the intensity of the filtered light in a specific region in the electromagnetic spectrum, preferably ultraviolet. The signal from the detector may be digitized and processed by a computer which classifies the sheet as either white or groundwood, and activates an ejection device to produce an air blast for diverting whichever grade is selected for ejection.

Filed: 1999-08-06
Abstract: Un système de radiocommunications supporte des techniques de correction d'erreurs sans voie de retour (FEC)/de demande de retransmission automatique (ARQ) permettant de traiter des blocs de données reçus de manière erronée. Des numéros de séquences associés à chaque bloc de données sont transmis indépendamment des blocs de données eux-mêmes, ce qui, entre autres avantages, réduit la latence et améliore l'utilisation de la mémoire. Une structure de redondance variable, plus robuste, est créée par découplage d'une transmission des données utiles provenant de l'identité de bloc ou de sous-bloc. Un groupe de numéros de séquence de bloc peut être transmis, par exemple en mode point, les numéros de séquence individuelle n'ayant pas besoin d'être complètement spécifiés. A l'inverse, un numéro de séquence individuelle peut être complètement spécifié, des numéros de séquences supplémentaires étant ensuite représentés par des décalages ou incréments ultérieurs à partir du numéro de séquence de départ.
