Patent CA-2174172-A1 (CA)
Title: Continuous in-situ combination process for upgrading heavy oil
Inventor: BRONS GLEN
IPC: C10G67/02
Filed: 1996-04-15
Abstract: The invention relates to  an integrated, continuous  process for  the  removal  of  organically  bound  sulfur  (e.g.,  mercaptans, sulfides and thiophenes)  comprising the steps  of contacting a  heavy oil, sodium hydroxide,  hydrogen and  water at a  temperature of  from about 380°C to  450°C to partially  desulfurize the heavy  oil and  to form  sodium  sulfide,  contacting  said  sodium  sulfide  via   steam stripping to convert the  sodium sulfide to  sodium hydroxide and  the sulfur  recovered  as  hydrogen  sulfide.   The  sodium  hydroxide  is recirculated for reuse.  The  partially desulfurized, dewatered  heavy oil is  treated  with  sodium metal  under  desulfurizing  conditions, typically at a temperature of from about 340°C to about 450°C, under a hydrogen pressure of at least about 50 psi to essentially  desulfurize the oil,  and  form  sodium  sulfide.   Optionally,  the  sodium  salt generated can  be  regenerated  to  sodium  metal  using  regeneration technology.    The   process   advantageously   produces   essentially sulfur-free product oils  having reduced nitrogen,  oxygen and  metals contents and reduced  viscosity, density, molecular  weight and  heavy ends.

Title: Rear wheel suspension for a bicycle and bicycle equipped therewith
Inventor: HARRIS TREVOR LEE
IPC: B62K25/30
Filed: 1995-09-11
Abstract: A suspension assembly (10) that is formed of an essentially horizontal swing arm (SA) which is pivotally attached at one end to the underside of a bicycle frame (F) by a pair of short links (L1,L2) and which carries the rear wheel (5) at an opposite end. The geometry of the suspension assembly (10) is designed to produce a substantially straight line trajectory of the rear wheel in an upward and rearward direction at an angle that is preferably 20-30° with respect to a vertical line through the wheel axis of rotation to increase traction, making the acceleration forces apply an upward vertical force component to the frame, and a downward component to the frame under braking, independent of wheel position, that reduces rear frame lift (pitch). Furthermore, to obtain a constant pedal "feel", the suspension geometry is also designed so that the maximum vertical height movement of the pedal crank axis of rotation can be kept to less than 5% of the vertical wheel travel (e.g., a. 25" crank axis height increase for a 4" vertical wheel travel). The suspension (10) is designed to attach to a standard frame (F) leaving room for mounting of the derailleur between the frame and the rear wheel. In a particularly preferred form, the swing arm assembly is provided with a tubular derailleur mount and an upper tube to which the rear wheel brake assembly can be mounted.

Patent CA-2191731-A1 (CA)
Inventor: WEISSER FRANK J JR
IPC: H04M3/42
Filed: 1995-06-05
Abstract: La présente invention concerne un procédé passerelle applicable à un échange de paquets de données par une interface spécifique, entre d'une part un réseau intelligent évolué exploité par un fournisseur de service d'exploitation de central local, et d'autre part un opérateur d'exploitation de central à distance. L'interface est définie entre le réseau intelligent évolué et un opérateur, ou plus précisément un équipement du réseau dudit opérateur exploitant de central. Cet équipement est notamment un point de contrôle de service (SCP) donnant accès au réseau intelligent évolué par une liaison de données en protocole SS7 connectant un équipement d'un exploitant de central local tel qu'un point de transfert de service (STP). Une procédure passerelle mise en oeuvre au niveau STP permet de réaliser certaines opérations de mise en conformité concernant les paquets de données reçus pourvus d'élément réseau de l'exploitant de central à distance. Tout paquet de données avec des valeurs non conforme sera rejeté. Mais les paquets de données avec des valeurs conformes seront remis à un SCP d'accès à passerelle pour la suite du traitement passerelle. Avant de poursuivre le processus d'acheminement du paquet de données (à l'exception du rejet de paquet de données), le SCP d'accès à passerelle supprime du paquet de données des informations comme celles portant sur l'origine du paquet de données (les numéro de transaction du paquet de données par exemple). Le SCP d'accès à passerelle met en mémoire ces informations supprimées, établit la relation logique entre ces informations supprimées et les informations de substitution qu'il a en base de données, et munit le paquet de données de ces informations de substitution en remplacement des informations supprimées. Les informations de substitution ne fournissent au destinataire du paquet de données aucune information concernant le fonctionnement du réseau. En sens inverse, à la réception d'un paquet de données, le SCP d'accès à passerelle recherche dans ce paquet les informations de substitution. Si le paquet de données reçu en sens inverse ne comporte pas les informations de substitution, il est rejeté. Si le paquet de données reçu en sens inverse contient les informations de substitution, et qu'il est par ailleurs conforme, le SCP d'accès à passerelle établit la relation entre l'information de substitution et les informations supprimées, et se sert desdites informations supprimées pour la suite de l'acheminement du paquet de données.

Title: Self-quenching fluorescence probe and method
Inventor: MULLAH BASHER KHAIRUZZAMAN
IPC: C12Q1/68
Filed: 1995-11-15
Abstract: An oligonucleotide probe is provided which includes a fluorescent reporter molecule and a quencher molecule capable of quenching the fluorescence of the reporter molecule. The oligonucleotide probe is constructed such that the probe exists in at least one single-stranded conformation when unhybridized where the quencher molecule is near enough to the reporter molecule to quench the fluorescence of the reporter molecule. The oligonucleotide probe also exists in at least one conformation when hybridized to a target polynucloetide where the quencher molecule is not positioned close enough to the reporter molecule to quench the fluorescence of the reporter molecule. By adopting these hybridized and unhybridized conformations, the reporter molecule and quencher molecule on the probe exhibit different fluorescence signal intensities when the probe is hybridized and unhybridized. As a result, it is possible to determine whether the probe is hybridized or unhybridized based on a change in the fluorescence intensity of the reporter molecule, the quencher molecule, or a combination thereof. In addition, because the probe can be designed such that the quencher molecule quenches the reporter molecule when the probe is not hybridized, the probe can be designed such that the reporter molecule exhibits limited fluorescence until the probe is either hybridized or digested.          designed such that the reporter molecule exhibits limited fluorescence until the probe is either hybridized or digested.
