Patent CA-2416532-A1 (CA)
Inventor: CARR J SCOTT
IPC: G06Q10/00
Filed: 2001-07-24
Abstract: La présente invention concerne des systèmes permettant de créer et d'authentifier des objets imprimés à l'aide d'un filigrane de détection de copie et d'authentification. Par exemple, un système de vérification comprend un décodeur de filigrane et un module de vérification. Le décodeur de filigrane détecte un filigrane de détection de copie dans un objet imprimé afin de déterminer si l'objet imprimé a été reproduit. Le module de vérification traite un message décodé à partir du filigrane d'authentification sur l'objet imprimé de manière à authentifier l'objet imprimé ou le détenteur de l'objet imprimé. Les filigranes de détection de copie et d'authentification peuvent être réunis en un seul filigrane ou ils peuvent être des filigranes différents. Par exemple, le filigrane de détection de copie peut être un filigrane fragile qui contient le message et qui se dégrade après une opération de reproduction, telle que la photocopie ou la lecture par balayage de l'objet puis la réimpression de l'objet. Dans un mode de réalisation différent, les filigranes de détection de copie et d'authentification peuvent être des filigranes séparés incorporés dans une image imprimée sur un objet. Dans certaines applications, le filigrane d'authentification comprend un identificateur qui relie l'objet à une entrée de base de données contenant des informations relatives audit objet. Ces informations peuvent être utilisées pour vérifier le détenteur de l'objet par comparaison de ces informations avec les caractéristiques du détenteur (par exemple, une photographie ou un identificateur d'utilisateur) ou pour vérifier la validité de l'objet par comparaison de ces informations avec les caractéristiques visibles ou pouvant être lues par une machine sur l'objet.

Patent CA-2434530-A1 (CA)
Inventor: KIMURA KEIICHI
IPC: D21F3/02
Filed: 2003-06-30
Abstract: In a shoe press belt of a papermaking machine, the part of the paper web-facing layer in which water-holding grooves are formed is composed of a surface sublayer, having a relatively low hardness, and an underlying layer having a relatively high hardness. The higher hardness of the underlying layer prevents cracks from forming where the cross-sectional shape of the grooves tends to change as the belt is compressed. The lower hardness of the surface sublayer prevents the formation of cracks as a result of forces acting on the belt in the direction opposite to the machine direction at the nip location in a papermaking machine.
Patent CA-2436070-A1 (CA)
Title: Fiber cooling of fuel cells
Inventor: BUNKER RONALD SCOTT
IPC: H01M8/12
Filed: 2003-07-24
Abstract: Fuel cells [50] for example solid oxide fuel cells require cooling to maintain temperature levels and remove thermal energy generated by the fuel cells [50].  The present invention provides a fuel cell assembly [10] comprising at least one fuel cell [50]. The fuel cell comprises an anode [22], a cathode [18], an electrolyte [20] interposed therebetween, an interconnect [24] which is in intimate contact with at least one of the anode [22], the cathode [18] and the electrolyte [20], at least one fluid flow channel [95] which is disposed within the fuel cell [50], and at least one fiber [40] which is disposed within the fluid flow channel [95]. The fiber [40]  disposed within the fluid flow channel [95] disrupts a fluid flow during travel of the fluid within the fluid flow channel [95] to generate unsteady wakes [501]. These unsteady wakes [501] enhance the local heat transfer characteristics adjacent to at least one fiber [40]. A higher Reynolds number enhances the heat transfer characteristics proportionately. Enhanced heat transfer characteristics increase the ability to remove heat more efficiently and more effectively. The enhanced heat transfer characteristics thus improve cooling ability and enable the maintenance of predetermined thermal gradients and temperature levels across the fuel cell assembly [10].

Title: Structure for accommodating cd changer
Inventor: ENOMOTO KENICHIRO
IPC: B62J11/00
Filed: 2003-08-06
Abstract: In a structure of accommodating a CD changer, in which the CD changer biased for turning toward a protruding position is covered with a lid plate closing an open end of an accommodating recess in a state in which the CD changer is in an accommodated position, an engagement portion is provided on the lid plate mounted to a support frame so that it can be slid between a disengaged position and an engaged position. A locking portion is provided on each of base plates so that the locking portion engages with the engagement portion in a state in which the lid plate is at the engaged position, and the engagement with the engagement portion is released in response to the sliding of the lid plate toward the disengaged position. A locking mechanism capable of locking the lid plate in the engaged position and releasing the locked state by a manual operation is provided between the lid plate and the support frame. Thus, it is possible to ensure that the CD changer cannot be turned undesirably to the protruding position.

Title: A reinforced flexible pipeline having a thermal barrier
Inventor: WEDEL-HEINEN JAKOB
IPC: F16L11/08
Filed: 2002-04-30
Abstract: A reinforced flexible pipeline, which has an inner liner whose inner side engages an inner reinforcement layer that may be formed by a so-called carcass, and on whose outer side at least a strength-imparting reinforcement layer is provided, has an additional barrier layer which is arranged between the inner liner and the inner reinforcement layer. The additional barrier layer is thermally insulating and/or chemically protecting. The additional barrier layer may be formed as a tape which is wound around the inner reinforcement layer, or may be composed of locking profiles which are wound around the flexible pipeline in a helix. The additional barrier layer may be made completely or partly of a polymer which may be thermoplastic, or is cross-linked completely or partly. Hereby, the pipe may be protected against temperatures above e.g. 130°C and may also be protected against attacks from methanol that contains water. By constructing the additional barrier layer of profiles it is additionally ensured that it can transfer great compressive forces to the inner reinforcement layer, without any risk of the liner being caused to float since it is supported evenly by the additional barrier layer.

Patent CA-2452434-A1 (CA)
Inventor: ROBERIE TERRY G
IPC: C10G11/05
Filed: 2002-07-09
Abstract: The sulfur content of liquid cracking products, especially the cracked gasoline, is reduced in a catalytic cracking process employing a cracking catalyst containing a high content of vanadium. The cracking process involve s introducing at least one vanadium compound into a hydrocarbon-sulfur containing feedstock to be charged to a fluid catalytic cracking reactor operating under steady state conditions and containing an equilibrium fluid craking catalyst inventory within the reactor. The amount of sulfur in the liquid products, in particular gasoline and LCO fractions, is reduced as a result of the increased vanadium content on the equilibrium catalyst. Advantageously, sulfur reduction is achieved even in the presence of other metal contaminants, such as nickel and iron, on the equilibrium catalyst.</S DOAB>
