Title: System, method and apparatus that employ virtual private networks to resist ip qos denial of service attacks
Inventor: MCDYSAN DAVID E
IPC: H04L29/08
Filed: 2002-03-20
Abstract: A network architecture (30) in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs) (44, 46). The communication network includes a plurality of boundary routers (40, 42) that are connected by access links (35) to CPE edge routers (34) belonging to the one or more VPNs (44, 46). To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS (Quality of service) provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN  traffic. Granting precedence to intra-VPN traffic over extra-VPN traffic in this manner entails special configuration of network elements and protocols, including partitioning between intra-VPN and extra-VPN traffic on the physical access link using layer 2 multiplexing and the configuration of routing protocols to achieve logical traffic separation. By configuring the access networks, the VPN boundary routers (40, 42) and CPE edge routers (34) and the routing protocols of the edge and boundary routers in this manner, the high-level service of DoS (Denial of Service) attack prevention is achieved.

Title: Procede de production en continu d'elastomere halogene et dispositif pour mettre en oeuvre ce procede
Inventor: IVANOVA SVETLANA ROMANOVNA
IPC: C08F8/20
Filed: 2001-04-02
Abstract: Le procédé de production en continu d'élastomère halogéné consiste à amener un agent halogénant dans un courant continu d'une solution d'élastomère, ledit agent se mélangeant et interagissant avec cette dernière de façon à produire l'élastomère halogéné, à neutraliser l'élastomère halogéné à l'aide d'un milieu neutralisant et à le laver au moins une fois au moyen d un milieu de lavage. On effectue l'halogénation, le lavage et la neutralisation dans des conditions turbulentes, sous l'effet d'inversion, qui sont suivies par l'évacuation successive de l'excédent d'agent halogénant et par la décantation des milieux de neutralisation et de lavage de l'élastomère halogéné. Ce procédé est mis en oeuvre par le dispositif de production en continu d'élastomère halogéné qui comprend des réacteurs d'halogénation, de lavage et de neutralisation. Chaque réacteur est muni de moyens statiques et dynamiques servant à assurer la turbulence sous l'effet d'inversion. En amont de chaque réacteur on monte un réservoir qui sert à évacuer l'excédent d'agent halogénant et à décanter les milieux de neutralisation et de lavage de l'élastomère halogéné.

Inventor: MASSENGALE ROGER DILLARD
IPC: A61M5/14
Filed: 2002-05-31
Abstract: A device and method for the infusion of medicinal fluid at a controlled flow rate to a wound site or the blood stream of a patient is disclosed. A pump (102) delivers fluid under pressure from a fluid source through a continuous and substantially constant flow path (106) and through a supplemental bolus dose flow path (108). A large volume bolus dose reservoir (110) accumulates a large quantity of fluid from the bolus dose flow path (108) and holds the fluid under pressure. A flow regulator (128) controls the fill rate of the large volume bolus reservoir (110). The large volume supplemental bolus dose is released from the bolus reservoir (110) upon patient activation of a valve (112). The release rate of the bolus dose is controlled by the decompression of an elastomeric sphere or spring chamber (210), by the pressure gradient at the valve and/or by optional flow control tubing. In one embodiment, a source of fluid under pressure is pumped at a continuous and substantially constant rate to a wound site or the blood stream of a patient and into a bolus syringe (302), which is capable of holding a large quantity of fluid under pressure. A  plunger (314) on the bolus syringe (302) may be depressed to release a bolus dose of fluid into a chamber accumulator (318) and then to the patient at a controlled release rate.

Inventor: KITTLE KEVIN JEFFREY
IPC: B05D1/00
Filed: 2002-06-06
Abstract: A process for forming a coating on a conductive substrate, including the steps of: establishing a fluidised-bed of a powder coating composition, thereby effecting tribostatic charging of the powder coating composition, the fluidised-bed including a fluidising chamber at least a part of which is conductive, applying a voltage to the conductive part of the fluidising chamber, immersing the substrate wholly or partly in the fluidised bed, whereby charged particles of the powder coating composition adhere to the substrate, the substrate being either electrically isolated or earthed, withdrawing the substrate from the fluidised-bed and forming the adherent particles into a continuous coating over at least part of the substrate. The process offers advantages in terms of coating substrate areas which, because of the Faraday cage effect, are incaccessible in conventional electrostatic powder coating processes, and also enables the formation of thinner coatings than are obtainable by conventional fluidised-bed processes. Further advantages include uniformity and speed of coating.

Abstract: An electrodialysis method and apparatus include a source of concentrate fluid, a source of dilute fluid, a collector of treated concentrate fluid, a collector of dilute fluid, an anode and a cathode. A plurality of generally planar spacers (12, 20, 28, 32) are interleaved with a plurality of membranes (18, 29, 40, 52) to define a plurality of cells providing electrically conductive fluid connection between the anode and the cathode. Each of the spacers comprises a gasket that defines a first aperture (22, 34, 36) and a second aperture (22~, 34~, 36~). Each of said first (22) and second apertures (22~) define an independent cell between interleaved membranes.
