Abstract: L'invention concerne un procédé et un dispositif permettant de déterminer les paramètres de classement d'une carcasse. Selon le procédé, on trace le contour d'une image de la carcasse et on identifie des points de référence représentant les caractéristiques anatomiques de ladite carcasse. Puis on identifie des seconds points de référence placés à des positions prédéterminées par rapport aux premiers points de référence. On divise l'image de la carcasse en une pluralité de sections, dont les limites sont déterminées en fonction de la position des premiers et des seconds points de référence, et on calcule la surface de chaque section. On calcule une équation prédictive des paramètres de classement, le paramètre de classement étant pris comme variable dépendante et au moins une surface d'une section de l'image de la carcasse comme variable indépendante. La solution de l'équation prédictive donne une valeur pour le paramètre de classement de la carcasse. Parmi les autres mesures pouvant être obtenues à partir de l'image de la carcasse et utilisées comme variables indépendantes dans des équations prédictives, on trouve la distances comprise entre les régions dorsale et ventrale du contour de l'image de la carcasse et l'axe de la carcasse, les largeurs de la carcasse, les mesures angulaires entre les points de référence et les mesures de la courbure du contour de l'image. Des techniques améliorées de repérage du faux-filet permettent de mesurer précisément les paramètres de ce dernier. Ces paramètres mesurés peuvent être utilisés pour déterminer la classe de qualité de la carcasse, ou comme paramètres indépendants dans une équation prédictive du paramètre de classement, seuls ou associés aux mesures prises à partir de l'image de la carcasse.

Abstract: A Z-fold mailer type business form intermediate using patterns of pressure activated cohesive has the cohesive in patterns for both sealing along the end and side edges of the final form in the form of discrete elements spaced from each other in such a way that when the business form is in either roll or stack format the individual cohesive elements substantially do not overlap each other. The cohesive elements typically are in the form of rectangles for example those along the end edges and the fold lines having a length of about .9 cm with space in between them of about 1.3 cm. The cohesive patterns along the side edges may be spaced from each other not only in a dimension parallel to the end edges, but also where cohesive patterns are provided on opposite faces of the second panel of the intermediate, they may be positioned so as not to overlap in a dimension parallel to the side edges

Abstract: L'utilisation d'un procédé de turbo-séparation par cyclone pour séparer efficacement, à partir d'un repas fondu pour animaux, une fraction à faible teneur en cendres contenant moins de 11 % en poids de matières non protéique, permet d'obtenir un rendement de matière à faible teneur en cendres, supérieur à 50 % en poids, en tant qu'aliment utilisable pour chiens et chats. Ce procédé consiste à créer, dans un premier turbo-séparateur (10) un double tourbillon d'air, l'un (20) extérieur et descendant et l'autre (22) intérieur et montant, et à ménager dans ce cyclone une chambre supérieure (11) pourvue d'un dispositif rotatif de rejet (13) de particules. La charge alimentaire animale fondue est fournie dans le tourbillon d'air montant (22), lequel entraîne et porte la fraction pauvre en cendres à travers le dispositif rotatif de rejet (13) de particules, en direction d'un second appareil (26) de nettoyage par tourbillon d'air. Puis on récupère la matière pauvre en cendres (23a) à partir de cet air d'entraînement, les particules les plus grosses et les plus denses et à forte teneur en cendres (41) étant récupérées à partir du premier turbo-séparateur.

Abstract: We have found that foam generated from an aqueous medium can have a thermal insulating effect. The creation of a substantial volume of foam on the surface of an aqueous medium can reduce the apparent thermal 1R emission substantially when compared to that of the aqueous medium free of foam. This difference in infrared emission can be used to control the addition of a defoaming agent to control foam in the aqueous medium. In the foam control method of the invention, an infrared detector is used to measure the infrared emission of an aqueous medium free of foam and during operations such a measurement is compared to the infrared emission of the aqueous medium under foaming conditions. As foam develops on the surface of the aqueous medium, the apparent thermal infrared emission from the foam is less than that of the aqueous medium free of foam. As the thermal IR emissions drop as foam develops, the difference between the apparent temperature of the foam and the aqueous medium, as measured as infrared thermal emissions, drops. Such a drop in temperature can be used to trigger the addition of a defoaming agent which can substantially reduce foam volume. As the foam volume is reduced, the thermal infrared emission of the aqueous medium returns to a value near the thermal inverting emission of the aqueous medium without foam. At this point, the addition of a defoami ng composition is substantially reduced or stopped. During the control method, a predetermined limit is established at which the defoaming composition is introduced into the aqueous medium. As long as the thermal infrared emission of the foamed aqueous medium is different than the thermal infrared emission of the aqueous medium without foam, the defoaming agent is continually added to the aqueous medium . Further, the method permits the amount of defoaming agent added to the aqueous medium to be in proportion to the difference in infrared emission above the preset predetermined limit.

Abstract: Procédé permettant d'obtenir des endoprotéases (ou zonases) ayant une valeur commerciale à partir d'oeufs de saumons de l'Atlantique produits dans des écloseries. L'éclosion synchronisée, par exemple par élévation de la température, est suivie par le filtrage à travers des toiles à fromage. Le filtrat (fluide d'éclosion) peut être stocké pendant des mois ou des années (selon les conditions) sans perte d'activité. Les matières étrangères sont éliminées par centrifugation (16.000g, 2 x 15 mn) après ajout d'urée (2 ou 4 M, ou plus). On obtient ainsi des zonases extrêmement pures par des procédures chromatographiques simples (filtration sur gel, chromatographie d'affinité, isoélectrofocalisation) qui permettent d'atteindre une pureté élevée une fois que ces trois phases ont été effectuées en séquence. Toutes les préparations de zonases de saumon possèdent des propriétés enzymatiques précieuses pour ce qui est de la protolyse, à la fois en termes de catalyse et de stabilité.

Abstract: L'invention concerne un procédé de commande de sondage d'une perforatrice. Dans ce procédé, un capteur de pression (20) mesure la pression dans un espace situé derrière des pistons (4a, 4b, 14a, 14b) supportant une tige (2). On utilise la valeur de pression mesurée pour surveiller une impulsion de retour réfléchie par la roche vers le trépan, puis, à travers l'appareil de forage, vers les pistons (4a, 4b, 14a, 14b). Cette impulsion de retour fait reculer les pistons, augmentant ainsi la pression dans l'espace derrière les pistons (4a, 4b, 14a, 14b), ce qui, à son tour, se traduit par une impulsion de pression (B) pouvant être détectée par le capteur de pression (20), et différant de la variation de pression normale (A) causée par le mouvement de percussion. Une unité de commande (21) utilise l'impulsion de pression (B) pour régler l'alimentation et la puissance de percussion de la machine de forage, ainsi que d'autres paramètres ayant un effet sur le forage. L'invention concerne également un appareil comportant des moyens pour mettre en oeuvre la mesure des impulsions de pression (B) selon ce procédé.
