Abstract: L'invention concerne une construction à traverses et montants, notamment pour façades ou toits à puits de lumière dans les champs de cadre desquels des panneaux de verre (100) peuvent être insérés. Ladite construction comprend plusieurs montants (1) entre lesquels sont fixées des traverses (2). Les montants (1) présentent sur leur face extérieure, côté bord, dans chaque cas une rainure (3, 4) destinée à recevoir une garniture d'étanchéité (5, 6). Il est prévu à proximité de ladite rainure (3,4) une rainure de drainage (7, 8) pour dévier des liquides. La traverse (2) située sur la face tournée vers la face extérieure d'une garniture d'étanchéité (12) présente côté bord, dans chaque cas, une rainure (10, 11) destinée à recevoir une garniture d'étanchéité (12), ainsi qu'une baguette de retenue (13), entre les rainures (10, 11). Selon l'invention, une pièce d'assemblage (40) montée côté avant sur la traverse (2) prolonge les rainures (10, 11) et la baguette de retenue (13) de la traverse (2) et recouvre au moins en partie la rainure côté bord (3) du montant. Cette configuration permet de monter aisément la traverse sur le montant. Une pièce d'assemblage peut être montée aisément pour obtenir la construction par chevauchement, sans qu'il soit nécessaire de pratiquer des entailles d'assemblage, de manière complexe, dans la traverse (2).

Abstract: Naturally occurring CD4+CD25+T regulatory cells (Treg) activily participate to the mechanisms of peripheral tolerance by negatively regulating autoimmunity.  However, the molecular mechanisms of in vivo induction of T reg remain largely unknown.  Regulatory T cells (Tr1) can be generated in vitro from human naive T cells by repetitive stimulation with immature or IL-10-treated DC. We previously reported that CD47 ligation by either CD47 mAb or a peptide of its natural ligand, i.c thrombospondin, induced naïve T cell anergy. Herein, we demonstrate that the CD47 mAb- induced anergic T cells were actively suppressing the proliferation and cytokine production of syngeneic effector T cells. T anergic/suppressors cells (Tas) produced little or no cytokine. The suppressive function required physical contact with the responder T cells and was IL-10 and TGF-.beta. independent. Tas displayed :1) increased expression of CTLA-4, OX40 and GITR;  2) decreased levels of CD40L and CD28 and 3) similar levels of FAS, FASL, CCR4 and CCR7 and CD25 compared to effector T cells. Both CD4+ and CD8+Tas suppressed effector T cells proliferation and none of them regulated DC maturation. Our findings demonstrate that ligation of an endogenous receptor, i.e CD47, on naive cells generates a distinct type of regulatory T cells (Tas) which produce no IL-10 but share phenotypic and functional features with both Treg and Tr1 described in human and mice. TAS  may be re-infused to patients suffering from a large variety of chronic inflammatory diseases, graft versus host disease, graft rejection and allergic diseases. Compounds inducing in vivo the activity of TAS may be used to treat the same patients.

Title: Trap and method for trapping flying insects
Inventor: PAZIK KAROL
IPC: A01M1/10
Filed: 2002-06-13
Abstract: A trap for insects, particularly for wasps, comprises a vapour chamber (2) having at least one insect entrance (26) defined in a wall of the vapour chamber (2), and a bait or collection chamber (6) couplable to the vapour chamber at a restriction (16). The restriction (16) is sized to control the movement of insects between these two chambers. In operation, attractant vapour from a bait source accumulates in the vapour chamber (2) and is released through the entrance (26). Insects attracted by the attractant vapo ur enter the vapour chamber (2) and are maintained in flight within it, the restriction (16) delaying their entry into the collection chamber (6) . Once tired, insects drop down into the collection chamber (6) where, in a preferr ed embodiment, they are immersed in a fluid and drowned.

Abstract: L'invention concerne un système et un dispositif de blocage de communications de service spéciales frauduleuses (Fig. 3) dans un système téléphonique longue distance. Les enregistreurs automatiques de numéros (ANI) relatifs aux numéros de départ chez les exploitants de centraux urbains (LEC) sont bloqués de manière à empêcher les communications de certains numéros d'appel spéciaux de service comprenant l'ANI, pour l'enregistrement de numéros d'appel de service spéciaux, dans la base de données du système de gestion de service d'exploitants longue distance (SMS). Les ANI devant être bloqués sont sélectionnés par le contrôle des fraudes sur la base de seuils de certains flux d'utilisation des réseaux. Lorsque les éléments de commutation, en exploitation longue distance, récupèrent un enregistrement SMS pour une communication de service particulière, on détermine si l'origine de la communication correspond à un ANI dans l'enregistreur SMS. Si tel est le cas, la communication est bloquée.

Title: Precoordination de liaison retour permettant de realiser un transfert entre zones de couverture traversees par une plate-forme emettrice-receptrice mobile
Inventor: HEILMAN RICHARD A
IPC: H04B7/185
Filed: 2002-07-24
Abstract: L'invention concerne un système et un procédé permettant de réaliser un transfert de liaison de communication par satellite avec une plate-forme mobile, telle qu'un aéronef, sortant d'une première zone de couverture et entrant dans une deuxième zone de couverture. Une liaison de communication terrestre connecte des stations terrestres dans chaque zone de couverture pour qu'elles communiquent entre elles et également avec une centre d'exploitation de réseau (NOC). A mesure que l'aéronef entre dans la zone de chevauchement entre les deux zones de couverture, une séquence de communication est lancée entre les stations terrestres et également entre chaque station terrestre et l'aéronef pour assurer la réception par l'aéronef de nouvelles attributions de liaison aller et de liaison retour, avant que ce dernier abandonne sa liaison de communication avec la première station terrestre pour commencer à communiquer avec la deuxième station terrestre. Le transfert de communication est réalisé en un temps inférieur à environ 30 secondes après qu'une des stations terrestres a détecté l'entrée de l'aéronef dans une zone de chevauchement prédéterminée entre les deux zones de couverture.
Patent CA-2453828-A1 (CA)
Title: Anti-knock device for vehicles with post-production turbochargers
Inventor: RIZUN PETER R
IPC: F02D41/00
Filed: 2004-01-14
Abstract: The invention is an electronic device that prevents engine knocking in aftermarket turbocharged vehicles. The device intercepts the crankshaft position/speed signal from a sensor typically mounted near the engine's crankshaft and sends a delayed version to the ECU, making the ECU believe that the crankshaft has not rotated as far as it really has.      The position/speed signal is digitally processed in a unique way that allows a low-cost microcontroller to be used to perform the signal retardation. The invention retards the timing by variable amounts in response to the turbocharger boost pressure. The retarded timing makes the engine run slightly cooler and prevents auto-ignition of the fuel - known as knocking - in the combustion chambers.

At a predetermined torque shear, the shearing element fails and the nut is freed to advance on the threaded member portion from the first temporary operating position to a second permanent operating position. The first fixed operating position is located at the top end of the member-threaded portion. The second operation position is located at the bottom end of the member-threaded portion so that the bearing plate is in abutting contact with the face of the rock formation.

Title: File splitting, scalable coding and asynchronous transmission in streamed data transfer
Inventor: DUNNING TED E
IPC: H04L29/06
Filed: 2002-11-09
Abstract: Files (2750) are divided into parts (2716, 2718) and at least some of the parts are transmitted to a client using a communication channel. At least so me of the transmitted parts are cached locally. This allows subsequent streamin g playback of the file while using 'less bandwidth by transmitting the part of the file that hasn't been cached, and combining the cached parts with the tramitted parts. In some embodiments, files may be represented at a low quality level by a first data set (2804), and at higher quality levels with additional data sets (2806). Data sets are cached locally, so that during subsequent streaming playback of the file, the quality level of the playback may be improved by sending additional data sets using bandwidth that would otherwise be dedicated to transmitting the cached data sets.
