Abstract: A bearing housing in a bowl of a vertical turbine pump for a lower bearing of a rotatable pump shaft on which an impeller is mounted includes a separable hollow substantially cylindrical housing body with upper and lower ends, having a radial flange at its lower end adapted for sealing attachment to a bottom face of the bowl such that it is capable of installation in and removal from the bottom face of the bowl, the housing body also having an inside diameter greater than an outside diameter of the shaft to provide a clearance therebetween. A bearing is fixed within the lower end of the housing body for journaling the shaft therein, and provision is made for sealing between the upper end of the housing body and an internal axial bore in the bowl. A seal is also provided between the lower end of the housing body and the shaft for excluding pumped fluid from the clearance. Pumped fluid pressure against the seal, as well as particle size of solids carried by the pumped fluid, is limited by a close clearance between the impeller hub and a restriction bushing mounted in the bearing housing. Flushing with clean fluid may be provided, flow of which fluid being permitted out of the clearance, between the housing and the shaft, through the seal.

Granted: 2005-06-07
Abstract: The present invention relates to a device which is used in the floating roofs of tanks for storing liquids and is intended to prevent the formation of a vacuum between the stored liquid and the floating roof (5). More particularly, the device of the invention is intended for a liquid storage tank which has operating heights which are much lower than the maintenance height. There are two possible ways in which the device of the invention can operate. When the floating roof (5) is in operating mode and reaches its minimum operating height (Figure 2), a lower shaft stop (10) of a sliding shaft of the valve comes against a lower stop (8) of the body (2) of the device, causing the device (30) to open. When the floating roof (5) is placed in the maintenance mode, use is made of a locking pin (4) for rigidly fastening the sliding shaft (3) to the body (2) of the device (30), which enables the assembly to open when the floating roof reaches the maintenance height.

Abstract: L'invention concerne une fonction de survol permettant de visualiser des données représentant un texte, des images, des sons, des mondes virtuels, des liaisons ou d'autres objets, et organisées dans une structure hiérarchique. Cette fonction est destinée à afficher et interagir avec les liaisons menant aux données. Un ensemble de données extrait est affiché dans une lentille et, par la suite, des ensembles de données extraits plus bas dans la structure hiérarchique sont affichés dans d'autres lentilles empilées, ce qui crée une représentation visuelle de la hiérarchie. Chaque lentille possède une étiquette qui fournit des informations relatives aux données initialement affichées dans la lentille. Un utilisateur peut choisir de visualiser sur l'écran les contenus initialement affichés de toute lentille. Un utilisateur peut également modifier une structure de données hiérarchique personnelle comportant des liaisons vers des ensembles de données de la première structure hiérarchique. Ainsi, un utilisateur crée une structure hiérarchique entièrement nouvelle qui personnalise l'organisation des données en fonction de ses préférences personnelles et exploite l'association naturelle dans le but de réduire le nombre de niveaux perçus de la nouvelle structure hiérarchique de données.

Abstract: Cette seringue est pourvue d'un dispositif interdisant une réutilisation, en l'occurrence, la tige support du piston (26) et l'embout de l'aiguille (38) sont détruits et l'aiguille (64) se retire dans la tige. Cet agencement, qui n'exige que l'application de davantage de force le long de la même ligne d'action que celle de la course d'injection, permet de procéder en toute sécurité à une injection d'une seule main, ce qui est essentiel dans certaines situations. Cet agencement permet également de réduire la quantité de produit médicamenteux gaspillé et ce, dans la mesure où la pointe (28) de la tige support du piston occupe tout le volume du cylindre (20). Il est possible d'utiliser cette seringue à aiguille rétractable qui fait appel à des systèmes de raccordement Luer-lok normalisés avec diverses aiguilles classiques pourvues d'une canule rétractable. Il est possible d'utiliser une grosse aiguille indicatrice pour remplir la seringue dans un flacon ou tout autre récipient avant de fixer l'aiguille de sécurité pour procéder à une injection. Le piston est, en dernier lieu, entièrement encapsulé par le cylindre, ce qui interdit la réutilisation de la seringue et permet de la jeter facilement et en toute sécurité.
