Inventor: BUSUIOC MARIUS NICOLAE
IPC: H04M15/00

Granted: 2002-04-30
Abstract: Un système permettant de détecter une fraude dans un réseau de télécommunications fait correspondre les informations concernant des appels individuels à une série de règles (18). Pour chaque règle (r), un seuil (T¿r?) est défini et, si la correspondance d'un appel individuel à cette règle est meilleure que T¿r?, une alarme est générée. Tous les enregistrements d'appels provoquant une alarme sont mis en mémoire dans un fichier de correspondance positive. De même, les appels qui manquent de peu à satisfaire aux critères, dans une certaine marge de tolérance .THETA., sont mis en mémoire dans un fichier de correspondance négative distinct. Les entrées dans les fichiers de correspondance positive et négative sont ensuite vérifiées par des opérateurs entraînés, qui déterminent laquelle en réalité représente une véritable fraude. Sur la base de ces validations, un module de décision incorporé au système calcule et met en oeuvre automatiquement les modifications nécessaires pour les seuils (T¿r?) au moyen d'une boucle de rétroaction.

Patent CA-2282640-C (CA)
Inventor: COMBS GEORGE
IPC: C08G65/10
Filed: 1998-03-02
Granted: 2007-06-19
Abstract: A process for making substantially non-crystalline double metal cyanide (DMC) catalysts having improved activity and performance is disclosed. The process comprises using a metal salt having an alkalinity within the range of about 0.2 to about 2.0 wt.% as metal oxide based on the amount of metal salt to prepare the catalyst. Surprisingly, important polyol properties such as viscosity and unsaturation improve when the alkalinity of the metal salt used to make the DMC catalysts is properly controlled. The process allows catalyst producers to enjoy the benefits of substantially non-crystalline DMC catalysts even when relatively inexpensive, technical-grade metal salts are used to make the catalyst.

Abstract: In a power transmission system for a four-wheel drive vehicle, a multiple disk clutch for distributing a proportion of the torque of the front wheels to the rear wheels is provided between a driving shaft which is connected to the front wheels which are main driven wheels and a driven shaft which is connected to the rear wheels which are auxiliary driven wheels. Between the driving shaft and the driven shaft a torque cam mechanism, a hydraulic pump and a bidirectional clutch mechanism are provided, in that order. When the rotational rate of the front wheels exceeds the rotational rate of the rear wheels, the bidirectional clutch mechanism is engaged, a first rotor of the hydraulic pump which is operatively connected to the front wheels and a second rotor which is operatively connected to the rear wheels rotate relative to each other, and a rotational load is generated by a hydraulic circuit. A first cam element and a second cam element of the torque cam mechanism rotate relative to each other as a result of the above-mentioned rotational load so as to generate a thrust force, and this thrust force causes engagement of the multiple disk clutch so as to put the vehicle into a four-wheel drive mode. It is thus possible to decrease the torque transmission capacity of the bidirectional clutch mechanism so reducing its size and cost.

Title: Flow modifier for submerged intake screen
Inventor: MAXSON RICHARD C
IPC: E02B5/08
Filed: 1999-09-24
Granted: 2002-05-14
Abstract: Improved flow modifier assembly (40, 60) for a water intake system having a cylindrical intake screen (44, 64) prevents damage to fish and other aquatic organisms by providing a controlled velocity profile which causes the average flow velocity (58) to closely approach the peak flow velocity. By extending two or more concentric tubular flow modifiers (42', 52) or (62', 67, 68, 69) into one end of the screen, it is possible to achieve flow uniformities of more than 90 %, as compared to a maximum of about 72 % for a prior art configuration utilizing a single tube flow modifier (22). In addition, the size, weight and cost of screen required can be greatly reduced for a given peak flow velocity as compared to prior art devices.
