Abstract: A  disposable   sterile   plastic   bag   is proposed for holding samples in blenders during the mixing  thereof  comprises  a  two-ply  sheet  flexible material  integrally  joined  at  opposed  side  edges thereof  and  joined  at  the  upper  and  lower  ends thereof respectively by upper and lower heat seals with a sealed sample receiving chamber being defined between the two plastic sheets inwardly of the bag's side edges and upper and lower seals. Inwardly of the upper  seal,  there  is  defined  a  tear  off  line transversally across the two sheets and parallelly to the upper seal  thereby forming  a detachable  strip outwardly of the tear off line. When the sample is ready  to be  introduced  in  the bag,  the  strip  is removed from the bag by pulling it so as to cause rupture of the two sheets at the tear off line. The bag's  chamber  is  thus  sterile when  the  sample  is introduced therein and the bag and its contents can then be inserted in the blender. The bag's sterility does not depend on how the bag is package or on the integrity  of  the  packaging's  seal  as  the  bag  is itself sterile until the strip is removed therefrom, that is until the bag is ready to be used.

Abstract: A temporary multimedia ELAN is formed on top of one or more existing ELANs between those end-stations (121-1, 121-2, 111-1) participating in a multimedia session, such as a video conference, at the time of initiating the session. At the end of the session the temporary ELAN is torn down. When the temporary ELAN is created an available LAN Emulation Server (LES) (241) and an available Broadcast and Unknown Server (BUS) (243) are allocated to serve those end-stations participating in the multimedia session. The BUS also serves as a multicast server to multicast a multimedia stream from one end-station to each other end-station on the temporary ELAN. The initiator of a session accesses a Multimedia Session Manager (401), which oversees and manages the session and coordinates the necessary resources. An ELAN Configuration (402) serves to dynamically assign IP addresses to end-stations to ensure that each end-station on the temporary ELAN is on a single subnet, to receive the configuration attributes of each end-station that is to be connected on the temporary ELAN, to find an available LES and BUS to serve the temporary multimedia ELAN, and to coordinate establishment of the temporary ELAN between the end-stations. Once the temporary ELAN has been formed, a Conference Configurator (403) starts executing a multimedia application already existing on each end-station or sends the executables of the selected multimedia application in real time to each end-station. During the session the Multimedia Session Manager is used to add a new end-station, drop an end-station, and terminate the session.

Abstract: Procédé permettant d'inhiber la formation d'hydrates de clathrate dans un liquide contenant des composants formant des hydrates, qui consiste à traiter le liquide avec un inhibiteur constitué d'un polymère pratiquement soluble dans l'eau ayant un squelette polymère comprenant un groupe alkyle C1-C3 pendant; le polymère ayant un poids moléculaire moyen se situant entre 1.000 et 6.000.000. De préférence, le groupe alkyle pendant est un groupe méthyle. On réduit le taux de nucléation, de croissance, et/ou d'agglomération des cristaux d'hydrate de gaz dans un flux d'hydrocarbures en utilisant l'inhibiteur à squelette polymère alkylé, de manière à inhiber la formation d'un blocage d'hydrates dans le conduit transportant le flux d'hydrocarbures. Des résultats d'expérimentation ont montré de façon inattendue que l'alkylation du squelette polymère avec un groupe méthyle va provoquer un sous-refroidissement du polymère alkylé qui est supérieur à celui de son homologue non alkylé d'au moins 2  DEG F (environ 1,1  DEG C). L'inhibiteur s'utilise facilement à basses concentrations, par exemple à des concentrations s'échelonnant d'environ 0,01 % à 5 % en poids de l'eau présente dans le flux d'huile ou de gaz, pour traiter efficacement un hydrocarbure à phase aqueuse.
