Abstract: A joint assembly is disclosed for connecting two spaced drive shafts, such as in a submergible pumping system. The joint assembly comprises a connecting shaft having enlarged bodies on each end thereof, a housing surrounding each enlarged body, each housing connectable to one of the drive shafts, lock devices for preventing relative rotational movement of the connecting shaft with respect to the drive shafts, and mechanisms within each housing acting upon the enlarged bodies to bias the connecting shaft into coaxial alignment with the drive shafts. With this joint assembly lateral displacement or "wobble" of the drive shafts is permitted, yet the bias mechanisms tend to restore the drive shafts to coaxial alignment.

Title: Redox and photoinitiator systems for priming for improved adherence of gels to substrates
Inventor: HUBBELL JEFFREY A
IPC: C09D7/00
Filed: 1996-03-22
Granted: 2008-11-25
Abstract: An improved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as "priming". the polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, "priming" can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other. A first surface and a barrier, or another surface, are prestained with initiator, and a thin layer of gelable monomer containing initiator is placed between them. Strong adhesion is obtained between the two surfaces on gelation of the monomer. In a similar fashion, tissue surfaces can be adhered to each other in repair of wounds and formation of anastomoses.  Methods for use of non-photochemical systems and combined chemical/photochemical systems are described.

Abstract: Using the Internet World Wide Web (WWW) network (320), a WWW client (310) ca n communicate  with a WWW Server (330) to request access to a user's voice mail. In order to satisfy this request, the user enters his voice mail mailbox number, and activ ates an appropriate hyperlink. The WWW Server then launches an application, MSG Clie nt (350), which in turn communicates with an application , MSG Server (370), that runs in conjunction with the voice mail system (380, 385, 390). In response to an initial message from the MS G Client, the MSG Server returns information about all voice mail messages wit hin the specified mailbox, which are displayed at the WW W Client. This display includes a hyperlink to each message in the mailbox. Th us a user can select a message from within the mailbox b y activating this hyperlink, which prompts the WWW Server to again launch MSG Client. This in turn sends a second message to MSG Server, which responds by returning the actual audio data for the selected m essage to the MSG Client, which is forwarded onto the WW W Client via the WWW Server. The WWW Client then plays out the audio data, all owing the user to hear his or her selected voice mail message.

Abstract: Procédé de fabrication d'immuno-essais à base d'épitopes à copies multiples qui consiste à: 1) identifier les séquences nucléotidiques qui codent plusieurs épitopes différents; 2) placer les séquences nucléotidiques dans une cassette d'expression; au moins deux copies d'une séquence codant pour le même épitope, provenant de préférence de souches différentes d'un pathogène, sont placées dans la cassette; 3) transformer un hôte convenable avec la cassette pour exprimer les séquences codant les épitopes; 4) purifier les épitopes exprimés; et 5) appliquer les épitopes à la surface d'un substrat. Les épitopes purifiés répondent à la formule structurale générale (A)¿x?-(B)¿y?-(C)¿z?, qui représente une séquence linéaire d'acides aminés, où B est une séquence d'acides aminés d'un épitope ou d'un groupement d'épitopes, chaque B comprenant au minimum cinq et au maximum mille acides aminés, où y est un nombre entier égal ou supérieur à 2, où A et C sont indépendamment l'un de l'autre des séquences d'acides aminés d'un épitope ou d'un groupement d'épitopes non adjacents à B de par sa nature, et où x et z sont égaux à 1 ou plus. Les épitopes de la présente invention sont plus solubles que les épitopes conventionnels et peuvent, de ce fait, être purifiés plus facilement. De plus, la présence de séquences répétitives d'épitopes (qui répètent au moins B dans la même séquence linéaire d'acides aminés provenant de souches différentes d'un pathogène) augmente la sensibilité et la spécificité de l'essai. Ladite présence de séquences répétitives d'épitopes dans un antigène linéaire isolé facilite également le masquage et permet d'inclure un nombre plus élevé d'épitopes dans une zone unitaire d'un substrat, ce qui augmente la sensibilité en matière de détection d'anticorps.

Abstract: Méthode de réalisation d'un pontage au moins partiel du coeur visant à suppléer aux fonctions de pompage du coeur et à permettre au chirurgien d'effectuer diverses opérations sur le coeur. On utilise à cet effet un système d'assistance circulatoire qui comprend une pompe axiale portable extracorporelle disposant d'un boîtier, d'un élément de pompage rotatif placé dans ledit boîtier et de canules d'entrée et de sortie, connectées aux orifices d'entrée et de sortie de la pompe. On accède à l'oreillette gauche du coeur du patient avec la canule d'entrée; on accède à l'aorte avec la canule de sortie; on met en marche l'élément de pompage rotatif pour attirer le sang oxygéné de l'oreillette gauche dans l'orifice d'entrée du boîtier de la pompe en passant par la lumière de la canule d'entrée. L'élément de pompage communique une énergie mécanique au sang oxygéné qui passe par le boîtier de la pompe et dirige le sang oxygéné, qui passe par l'orifice de sortie et par la lumière de la canule de sortie, vers l'aorte qui le transporte vers les artères systémiques. Cette disposition permet au côté droit du coeur de fonctionner; de cette manière, le sang appauvri en oxygène retournant par les veines systémiques dans l'oreillette droite est chassé à travers le ventricule droit vers les poumons du patient où il subit une oxygénation et fait ensuit le mouvement de circulation pulmonaire.
