Abstract: La présente invention a trait à un outil pour façonner une pièce comportant une fente prévue entre une paire d'extrémités à son extrémité distale. Les extrémités sont montées de tranchants. La fente est conformée pour la réception d'une plaque. L'outil comporte un conduit s'étendant selon son axe pour la communication de fluide sous pression à la fente et à la plaque. La plaque oriente le flux de fluide sous pression vers l'extérieur en direction des extrémités. La force vers l'extérieur conséquente entraîne la flexion vers l'extérieur des extrémités, sollicitant ainsi le tranchants vers l'extérieur pour la découpe, l'alésage, ou autre traitement de la pièce. La résilience de l'outil entraîne le retour vers l'intérieur des extrémités lors de la réduction de la pression de fluide. Une plaque peut être conformée pour la réception d'une plaquette pour le transfert de force depuis le fluide sous pression vers les extrémités.

Abstract: This invention is in the field of animal feed, more in particular in the field of fish feed. Surprisingly, it has been found that the seasonal mobility period of fish may be lengthened by interfering with the diet of the fish. We found that it is possible to increase the seasonal mobility period of fish to such an extent that it is even active at temperatures as low as 2 degrees Celsius. Such may be accomplished by adding naturally occurring substances to the feed of the fish. Examples of these naturally occurring substances are immune enhancing ingredients like beta-glucans and/or small amounts of phytohormones like auxin or gibberellic acid. Also, combinations of these substances, in particular the combination of beta-glucans and phytohormones, were shown to have a synergistic effect in that they lengthened the seasonal mobility period of the fish more than the individual components on their own.

Title: Scroll compressor with bifurcated flow pattern
Inventor: WEHRENBERG CHRIS A
IPC: F04C18/02
Filed: 2004-02-09
Granted: 2011-12-13
Abstract: A scroll compressor includes various features that promote a bifurcated flow pattern of gas through a compressor shell to reduce oil entrainment. After entering the shell, some gas travels upward, which reduces the volume of gas traveling downward toward an oil sump. To accomplish this, the compressor's motor can be surrounded by a sleeve having upper and lower apertures for directing the flow to the motor's upper and lower stator end turns. In some embodiments, a suction inlet is strategically positioned relative to two gas passageways that are between the stator and the compressor shell. The inlet's position is such that one passageway receives incoming gas and divides the flow in opposite directions: upward and downward. The other passageway only conveys the gas upward. In addition, a suction baffle, a diffuser, a streamlined counterweight and/or a suction line oil trap can also help promote gas/oil separation or minimize oil entrainment.
