Title: Ultrafiltration et microfiltration de suspensions aqueuses
Inventor: CRAGG GEORGE ALFRED
IPC: B01D71/32
Filed: 2000-06-02
Abstract: L'invention porte sur un procédé d'ultrafiltration et de microfiltration qui consiste à mettre en contact une suspension de particules dans une suspension aqueuse avec une structure membranaire microporeuse dont la taille des pores est efficace pour rejeter des particules comprises entre 0,01 et 10 µm. Au moins une partie de la structure membranaire en contact avec la suspension a une tension superficielle inférieure à celle du polytétrafluoroéthylène. Il est possible d'obtenir une faible tension superficielle en recouvrant un substrat microporeux d'une substance tel qu'un polymère de dioxole substitué par le fluor. Ce procédé de filtration a une bien meilleure résistance à l'encrassement et peut produire un écoulement de filtrat continu supérieur à 100 L/(m?2¿-h) sur plus de 150 heures. Ce nouveau procédé est utile dans de nombreuses applications, utilisant des membranes d'ultrafiltration et de microfiltration susceptibles de s'encrasser, telles que la filtration de déchets des eaux usées provenant des bateaux.

Title: Immunomodulation by genetic modification of dendritic cells and b-cells
Inventor: CURIEL DAVID T
IPC: A61K39/00
Filed: 1999-09-28
Abstract: A gene delivery vector is used to generate genetically modified dendritic cells and B-cells central to the immune system. As a result, genetic modification of cells bearing the CD40 target antigen on its surface can be used to modulate immunity. Previously, both dendritic cells and B-cells have  been resistant to gene transfer. The present invention serves to mediate dramatic enhancements in gene transfer to these cell types. Simultaneous wit h gene transfer, the vector system described herein matures dendritic cells an d B-cells to a more potent immunoregulatory status. This invention provides technology for genetic manipulation of dendritic cells and B-cells.

IPC: H04B7/26

Abstract: A method and apparatus for detecting forward and reverse link imbalances in a digital cellular communication system. The method preferably uses an indication of "maximum access probes" (104) to determine whether a link imbalance caused a reverse link failure to occur. The maximum access probes condition indicates that a wireless unit has attempted to access a base station a pre-defined maximum number of times. The method preferably uses an, indication of a lost paging channel (132) and a traffic channel initialization (TCI) time out (160) to determine whether a link imbalance caused a forward link failure to occur. If the wireless unit did not lose the paging channel (132), the method determines whether a TCI time out occurred (160). If the wireless unit lost the paging channel, or it did not lose the paging channel but a TCI time out occurred, the method determines the cause for the forward link failure. There are two potential causes in this scenario: (1) either the wireless unit is a significant distance from the base station; or (2) the paging channel suffers from significant interference. The method determines the cause and either instructs the wireless unit to perform an idle handoff to a neighboring base station or to exit the digital system.
