Title: Method for reducing load of traffic plane function
Inventor: WU YAJUAN
IPC: H04W4/24
Filed: 2005-08-10
Granted: 2011-02-08
Abstract: The present invention discloses a method for reducing the load of Traffic Plane Function (TPF). The key of the method is that, according to the obtained indication on whether to perform charging, the TPF determines whether to perform charging operation for the service data flow using appropriate charging rules, if yes, the TPF  performs the charging operation for the counting result of the service data flow and submits the charging information to the charging associated entities; otherwise, the TPF  does not perform the charging operation for the counting result of the service data flow. By applying this invention, operation in the TPF is optimized such that the TPF  only needs to perform necessary charging instead of performing charging operation for the service data flow which does not need to be charged. As a result, the load of the TPF is reduced, so is the load of network devices, and system efficiency is improved. Meanwhile, it is possible to avoid the waste of network resources aroused by various charging policies adopted by the operators, e.g., free of charge policy.

Title: Procede et appareil de separation des interferences isobariques
Inventor: LITHERLAND ALBERT EDWARD
IPC: H01J49/04
Filed: 2005-10-28
Granted: 2016-12-06
Abstract: Cette invention concerne un procédé et un appareil servant à séparer les isotopes stables ou radioactifs rares de leurs isobares atomiques ou moléculaires en spectrométrie de masse (MS). Dans cette invention, l'approche choisie pour éliminer les isobares atomiques utilise un dispositif de transmission élevée pour décélérer les ions en association avec des réactions de faible énergie, telles que des réactions ions-molécules ou le transfert d'électrons quasi-résonants, dans des guides d'ions RF. L'isobare est appauvri sélectivement par transfert d'électrons ou par d'autres réactions entre les ions négatifs et les cibles gazeuses dans les guides d'ions RF sous pressions à de faibles énergies. L'énergie est régulée de façon à empêcher la réaction de l'ion d'intérêt, tout en produisant des réactions avec l'interférence isobarique non souhaitées. Cette technique est particulièrement pertinente pour la spectrométrie de masse par accélérateur (AMS) qui permet des réductions sensibles de la tension nécessaire aux bornes. Cette technique a pour effet de permettre des réductions de la taille et du coût des installations (AMS).
Patent CA-2592568-C (CA)
Title: System and method for on-line cleaning of black oil heater tubes and delayed coker heater tubes
Inventor: GIBSON WILLIAM C
IPC: C10B43/08
Filed: 2007-06-20
Granted: 2011-03-22
Abstract: A system and method whereby on-line cleaning of black oil heater tubes and delayed coker heater tubes may be effectuated by injecting a high pressure water charge through the tubes during normal process operations so as to prevent tube fouling and heater downtime. The high pressure water charge begins the on-line cleaning process once it enters the heater tube by undergoing intense boiling and evaporation. The cleaning occurs by two methods - a scrubbing action and a shocking action. The scrubbing action occurs because of the complete turbulence caused by the water charge's intense boiling within the heater tubes. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes.
