Patent CA-2215779-A1 (CA)
Inventor: AOKI TAKASHI
IPC: H04M3/48
Filed: 1997-09-18
Abstract: A CPU calls in accordance with a MW call-back request one of MW call-back candidates registered in a MW call-back candidate memory region to correspond to a called extension terminal issuing a MW call-back request.  When a plurality of MW call-back candidates are registered to correspond to the called terminal, one of the MW call-back candidate terminals which corresponds to one of the count values stored in the count value memory region, which corresponds to the requesting terminal issuing the MW call-back request, is determined as destination terminal.  When no response to the MW call-back is obtained, the CPU changes the destination terminal to be called back the next by the same requesting terminal by changing the count values of the MW call-back candidates, which are provided to correspond to the requesting terminal.

Patent CA-2228159-A1 (CA)
Inventor: MELCHNER HARALD VON PROF DR
IPC: A61K48/00
Filed: 1996-02-23
Abstract: Cette invention concerne la production de vecteurs pour thérapie génique somatique. Ces vecteurs transduisent une unité de transcription complète contenant un promoteur, une séquence de codage de protéine et une séquence de polyadénylation, en un génome de cellules de mammifères. Lors de l'intégration, les vecteurs suppriment la plupart des séquences virales et non virales qui ne sont pas liées à l'unité de transcription, ce qui permet d'éviter les problèmes courants que l'on rencontre avec des vecteurs de rétrovirus classiques, tel que la répression de l'expression génique par l'atténuation de transcription, la mobilisation de rétrovirus endogènes, l'activation d'oncogènes ou le développement d'une réponse immunitaire. Cette invention utilise, d'une part, (i) le cycle de vie naturel des rétrovirus, ce qui implique la duplication des zones témoin terminales U5 et U3 de manière à produire des répétitions terminales longues (LTR), et d'autre part, (ii) la capacité de recombinases spécifiques à un site à exciser du génome de mammifère toutes les séquences se trouvant entre deux séquences cibles spécifiques. Les rétrovirus décrits dans la présente invention transduisent ainsi les séquences de codage d'une recombinase spécifique à un site et au moins une séquence cible spécifique à la recombinase en ce génome, ainsi que l'unité de transcription exprimant un gène thérapeutique.

Title: On-board refueling vapor recovery system
Inventor: PALVOELGYI SANDOR
IPC: B60K15/04
Filed: 1998-04-30
Abstract: The present invention is an on-board refueling vapor recovery system for a motor vehicle comprising a fuel tank constructed to store a quantity of liquid fuel. A nozzle-receiving portion has a nozzle-receiving opening fluidly communicated with the fuel tank. Closure structure is constructed to be moved into closing engagement with the nozzle-receiving portion to close the nozzle-receiving opening. An exhaust passage communicates the fuel tank to an atmosphere outside of the motor vehicle to thereby allow fuel vapor to vent from the fuel tank to the atmosphere. The exhaust passage includes a filtration device communicated with the fuel tank to filter environmentally harmful elements from the fuel vapor as it vents from the fuel tank to the atmosphere. A closure structure sensing device is configured to transmit electric signals based on whether the closure structure is in closing engagement with the nozzle-receiving portion. A valve control unit is configured to control whether the valve is opened or closed. The control unit is responsive to the electric signal from the closure sensing device and to a signal from the motor vehicle indicating whether the motor vehicle ignition has been activated. The valve control unit opens the valve to communicate the fuel tank with the filtration device to thereby allow the fuel vapor to be filtered and vented from the fuel tank to the atmosphere through the exhaust passage in response to the signal indicating that the motor vehicle ignition has not been activated in combination with the electrical signal from the closure structure sensing device indicating that the closure structure has been moved out of closing engagement with the nozzle-receiving portion. The valve control unit closes the valve to prevent communication between the fuel tank and the filtration device in response to the signal that the motor vehicle ignition has been activated.

Title: Bras de securite
Inventor: LAMPARTER RONALD C
IPC: B60R21/34
Filed: 1998-05-13
Abstract: L'invention porte sur un bras de sécurité comprenant une ou deux tiges creuses et effilées, ayant la forme d'une canne à pêche, dont le talon est monté en porte-à-faux sur la partie de montage du profilé d'un pivot/bride combiné.  Un élément transversal relie les pointes des tiges.  Le pivot/bride combiné se fixe de façon rotative à un support sur la partie avant de l'autobus pour empêcher les piétons de traverser juste en avant de l'autobus lorsque ce dernier est arrêté.  Les tiges sont effilées du côté de la masse et de la coupe transversale, du talon jusqu'à la pointe.  L'effilement concentre la masse de la tige plus près du support afin d'atténuer la tendance des tiges en porte-à-faux de fléchir sous leur propre poids et/ou de pivoter vers l'avant au moment où l'autobus décélère.  Il accroît également la flexibilité des tiges pour prévenir toute déformation plastique et pour réduire les charges sur le support lorsque des forces externes sont appliquées sur les tiges.  Un volet est fixé de façon pivotante sur une des tiges pour rendre ces dernières plus visibles sans créer une importante résistance au vent.  Le pivot/bride combiné comprend un corps en forme de U ayant un profilé reliant intégralement les bras pivots supérieur et inférieur.  Une patte de montage des tiges se prolonge intégralement en s'éloignant du profilé.  Des logements supérieur et inférieur dans la patte de montage reçoivent les talons des deux tiges.

Filed: 1996-12-18
Abstract: A device in the form of a funnel (1) and comprising a holder (2) and a folded bag (36), for filling a container (8) such as an oil barrel or a standard container such as a type IBC, in such a manner that the bag forms an insulated lining between the product, e.g. oil, with which the container has to be filled, and the actual container. The device further comprises a lining (24) for mounting in the container's filling opening (10), and in the lining there is mounted a bottom member (22) which is surrounded by the bottom of the bag (36), the latter and the bottom member being pushed into the bag's main part from the top and down through the bag's opening (23). When the container is filled the funnel (1) is first screwed by means of the lining (24) into the filling opening (10), and a supply pipe (14) with enclosed push rod (18) is pushed down through the holder (2), passing the bag (36) in an evacuated state down to the bottom of the container. Special design of the bag (36), axial slots (16) at the bottom of the supply pipe (14) and guide elements (46, 46') ensure that the bag is expanded in the correct manner during filling. At the bottom of the push rod (18) there is a closing/push piston (20) which closes the supply pipe during the final phase of filling. After filling the lining (24) is kept screwed into the container and is closed by a lid (19), until the container is empty and a new funnel has to be mounted thereon.

Title: Methods for modifying 1,3,5-triazine derivatives
Inventor: TANAKA NORIO
IPC: C07D251/40
Filed: 1996-12-24
Abstract: A method for modifying 1,3,5-triazine derivatives characterized by reacting a 1,3,5-triazine derivative having at least one amino or monosubstituted amino group on any of the ring carbon atoms with an alcohol by heating in the presence of a metallic catalyst and hydrogen to thereby introduce an alkyl or alkenyl group into each amino or monosubstituted amino group; another method for modifying 1,3,5-triazine derivatives characterized by reacting a 1,3,5triazine derivative having at least one amino or monosubstituted amino group on any of the ring carbon atoms with a dihydric alcohol by heating in the presence of a metallic catalyst and hydrogen to thereby introduce a hydroxylated alkyl group into each amino or monosubstituted amino group; and 1,3,5-triazine derivatives obtained by the methods. The various modified substituted 1,3,5-triazine derivatives thus produced are generally obtained as a mixture. These derivatives can be isolated as high-purity compounds by a general separation method for organic compounds, and the compounds are usable in the various applications mentioned in the specification. According to applications (for example, use as modifier additives, in particular a flameretardant and a plasticizer for resins), the reaction mixture can be used as it is without being separated. Many of the substituted triazine derivatives obtained have been relatively difficult to synthesize or expensive. Since many of the derivatives are interesting with respect to their physical properties, e.g., solubility in water and in various organic solvents, high-temp. stability, melting point, boiling point, and basicity, they are thought to have a wider range of applications than conventional ones.
