Granted: 2002-09-10
Abstract: Cette invention a trait à un système rendant possible l'évacuation de liquides indésirables, en phase aqueuse, d'une manière générale, précipitant au fond de cuves de stockage de produits liquides. Le dispositif de vidange (30) utilisé comporte un corps concave (31), un siège (26) et un flotteur de séparation (8) pourvu d'un partie d'obturation (25). Ce flotteur (8) est conçu pour plonger dans le produit en phase aqueuse et y flotter. Lorsque le niveau de produit en phase aqueuse descend, la partie d'obturation (25) se fixe de manière hermétique sur le siège (26) faisant, de la sorte, cesser le processus de vidange puisque tout le produit en phase aqueuse accumulé a déjà été évacué. Le système de vidange peut être automatique ou manuel. Dans le premier cas il est fait usage d'un capteur (12) destiné à déceler la présence d'un produit en phase aqueuse et à commander la procédure d'ouverture d'une vanne de fermeture (11) et, partant, à permettre la vidange du produit en phase aqueuse accumulé. Dans le cas d'un fonctionnement commandé manuellement, un opérateur inspecte périodiquement, grâce à une ouverture (28), la cuve de stockage (1) afin d'y déceler la présence d'un produit en phase aqueuse. Si celui-ci est en train de s'y accumuler, il ouvre une vanne de fermeture (11) à commande manuelle (29) afin de procéder à son évacuation.

Granted: 2006-06-20
Abstract: The multi-layer film structure having an inner sealing layer which comprises metallocene resin, a core which includes polypropylene copolymer and an outer layer and wherein the multi-layer film structure has a thickness within a range between about 50 and 70 microns (2.0 - 2.75 mil). By utilizing this thin film with specific properties the sealers may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10.degree.C to 15.degree.C and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This results in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength. The machine accomplishes better seals with less energy, requires less downtime for roll changes and maintenance and increase throughput.

Granted: 2007-09-04
Abstract: A thermal barrier coating system for a superalloy substrate is disclosed. The superalloy is preferably of the type that is capable of forming an adherent alumina layer. A bond coat is applied to a local area of the substrate, so that a portion of the substrate remains exposed. The localized area is defined to be the area(s) at which a TBC typically fails first, e.g., the leading and trailing edges of an airfoil, or other area. An alumina layer is formed on the remaining portion of the substrate, and also on the bond coat. A ceramic layer is then applied on the alumina layer. Even if the ceramic material is removed, the localized bond coat remains, and reduces the rate at which the underlying substrate oxidizes. A coated article is also disclosed, as is a system that utilizes a conventional superalloy and aluminide coating with the localized bond coat.

Filed: 1999-07-20
Granted: 2003-03-25
Abstract: According to the two party authentication method, a first party generates and transfers a random number to a second party as a first challenge. The second party increments a count value in response to the first challenge, generates a first challenge response by performing a keyed cryptographic function (KCF) on the first challenge and the count value using a first key, and transfers the count value, as a second challenge, and the first challenge response to the first party. The first party verifies the second party based on the first challenge, the second challenge and the first challenge response. The first party also generates a second challenge response by performing the KCF on the second challenge using the first key, and transfers the second challenge response to the second party. The second party verifies the first party based on the second challenge and the second challenge response. For instance, the first and second parties can be a network and mobile, respectively, in a wireless system. Also, based on the first and second challenges, both the first and second parties may generate another key.

Abstract: A workflow-manager (150) reserves a resource for processing an anticipated real work item by sending a simulated, artificial, work item to the resource before the real work item becomes available. The resource does not process the simulated work item, but rather awaits the real work item. When the real work item becomes available, it is substituted for the simulated work item, and the resource processes it.      For example, in an ACD system (101) that processes various types of communications, it is anticipated on a per-type basis how many agents (102-104) will be needed (202) versus how many are available (204). Any shortfall is cured by generating (210) tokens representing that many simulated communications of that type and enqueuing, dequeuing, and assigning the tokens to agents like any other arriving communications. Any excess is cured by canceling (210) that many outstanding, pending, tokens of that type. When a real communication of that type arrives (300), it is substituted (312,314) for the oldest token of that type, either in queue or at an assigned agent. To be fair to all agents, an assigned token is periodically reassigned from one agent to an available another agent.
