Patent CA-2260354-A1 (CA)
Title: Network controller and method of establishing a logical connection in a synchronous digital communications network
Inventor: SIGLOCH RAINER
IPC: H04J3/16
Filed: 1999-02-12
Abstract: Conventional synchronous digital communications networks are static networks which can be adapted to short-time load fluctuations only to a limited extent.      This situation is improved by a network controller (NSE) which serves to establish logical connections in the synchronous digital communications network. The network controller comprises access means for receiving a request for a logical connection from a customer, selecting means for selecting a path for the logical connection to be established, and means for initiating the establishment of the logical connection over the selected path.

Title: Method and telecommunications unit for establishing a telecommunications link in superposed digital radio networks
Inventor: SPERBER CHRISTOPH
IPC: H04W76/10
Filed: 1999-02-16
Abstract: In a method for establishing a telecommunications link by means of bursts in a digital radio network having at least one other digital radio network superposed thereon, the bursts of the two digital radio networks have the same bit structure but differ in a specific bit sequence (training sequence), and this training sequence of a burst is checked during the establishment of the telecommunications link. By processing only bursts with the training sequence(s) of the desired digital radio network, erroneously received other bursts are filtered out and discarded.

Title: Protein inhibitor of neuronal nitric oxide synthase
Inventor: JAFFREY SAMIE R
IPC: G01N33/50
Filed: 1997-08-29
Abstract: An nNOS associated protein designated PIN-1 (Protein Inhibitor of nNOS) has been identified. It physically interacts with nNOS and inhibits its activity.  Multiple lines of evidence indicate that PIN-1 is a regulator of nNOS: it is physiologically associated with nNOS, and it inhibits its catalytic activity.  The extraordinary evolutionary conservation of PIN-1 and preliminary evidence that it interacts with multiple proteins, suggests that it may be a major biological regulatory protein influencing numerous physiological processes.

Title: Gasoline vapour recovery method and apparatus
Inventor: VERBEKE RODNEY R
IPC: B65D90/30
Filed: 1999-04-15
Abstract: This invention relates to an improved gasoline vapour recovery method and apparatus used in association with underground or inground gasoline storage tanks normally vented to atmosphere. The operation of filling the underground tank creates pressure creating gasoline vapours which either directly exhaust to atmosphere or are collected by means of a recovery system in the gasoline delivery truck. According to this invention an apparatus is provided for installation on the venting system comprising a chamber having a first valve means adapted to close in response to a first pre-determined pressure in the chamber. This closure enhances and improves the gasoline vapour recovery operation. A second valve means is provided adapted to open in response to a second and higher pre-determined pressure in the chamber in order to exhaust the pressure creating gasoline vapours to atmosphere through a whistle alarm as required.
Patent CA-2269560-A1 (CA)
Inventor: GREWE TIMOTHY M
IPC: B60L50/15
Filed: 1999-04-20
Abstract: A controller for a hybrid electric system such as a hybrid electric vehicle includes a load, a battery, and a controllable source of auxiliary electricity. The state of charge (SOC) of the battery is estimated, and an error signal is generated which represents the difference between a desired and actual SOC. The SOC error signal is processed by at least integration, to produce a source signal representing the desired auxiliary source current. A second error signal is generated between the actual current from the auxiliary source and the desired current from the auxiliary source. The second error signal is processed, at least by integration, to produce a control signal for controlling the auxiliary signal source.
Patent CA-2271425-A1 (CA)
Inventor: RAHMAN AKBAR
IPC: H04W36/12
Filed: 1997-11-11
Abstract: La présente invention concerne un certain nombre de logiques permettant de remettre des messages numériques de données à des stations mobiles (18) pour lesquelles le canal de commande actuellement sélectionné est un canal analogique. L'un des procédés consiste à envoyer à la station mobile un signal (104) lui demandant de faire une resélection de serveur (106) et de choisir le meilleur canal de commande numérique disponible. Une fois que la resélection est effectuée, la remise du message numérique de données se fait de façon conventionnelle (110) en passant par le canal de commande numérique. Un autre procédé consiste à reformater (126) le message numérique de données en vue d'une remise en mode analogique, puis à envoyer le message reformaté, soit via le canal de commande analogique (128), soit via un canal vocal analogique (142) sélectionné. Un procédé encore différent consiste à établir avec la station mobile une liaison téléphonique (150) via un canal vocal et à émettre via le canal vocal un message audible synthétisé (154) correspondant au message numérique de données une fois que l'abonné considéré à réagi à la liaison téléphonique. Lorsque la remise de message via le canal de commande est interrompue en raison du déplacement de la station mobile, on procède à un nouvel enregistrement forcé faisant suite à la resélection du nouveau serveur, ce qui permet de déclencher la poursuite de la remise de messages via le nouveau canal de commande.

Patent CA-2277023-A1 (CA)
Inventor: BEGIN LAURENCE C
IPC: C06D5/06
Filed: 1998-01-29
Abstract: High nitrogen gas generant compositions, useful for inflating passenger restraint gas inflator bags, comprise a nitrogen rich coordination compound selected from coordination complexes comprised of anionic nitro and nitrito ligands coordinated with a transitional metal template, and nonmetallic or nonmetallic/metallic cations. The gas generant compositions generate relatively more gas and less solids, and are safer than known gas generant compositions. Certain gas generant compositions ignite at lower autoignition temperatures thereby facilitating the use of an aluminum or light weight metal pressure vessel. Other gas generants self-deflagrate eliminating the need for other constituents in the composition. Novel methods for the synthesis of nonmetal derivative coordination complexes, guanidine and hydrazine for example, are also presented.

Title: Method and apparatus for cascading frequency doublers
Inventor: KIYOKAWA MASAHIRO
IPC: H03B19/14
Filed: 1999-09-03
Abstract: This invention provides a multistage frequency multiplier having a plurality of frequency doubters. Each doubter incorporates a three-terminal transistor device and is connected to an adjacent doubter via an interstage network. The network comprises a transmission line having its electrical parameters selected to achieve conjugate impedance matching at the intermediate harmonic frequency generated by the corresponding doubter. This network also includes a quarter-wavelength open-ended stub for suppressing a main input frequency component received by the corresponding frequency doubter. A  shunt resistor on the transistor gate is preferably used to stabilize the network.  This interstage network simplifies overall circuit topology to reduce total circuit size, and provides increased drive power levels to permit broader bandwidth and stabilize required output level from a local oscillator. This invention is particularly useful in high-speed, large-capacity communications systems and in microwave and millimeter-wave radar applications.
Patent CA-2282285-A1 (CA)
Title: Storage system
Inventor: LAROCQUE JEAN-LOUIS
IPC: B65G1/02
Filed: 1999-09-17
Abstract: The invention relates to a system for storing a plurality of loads within a storage bay. The system comprises a pair of primary rails, and at least one pair of auxiliary rails positioned between the pair of primary rails. Carts of progressively narrowing widths are nested together at the front end of the rails. The carts are moved along the rails as loads are stored thereon. The widest cart is uppermost in the nested cart configuration and has wheels which roll along the outer edge of the pair of primary rails. The adjacent cart rolls along the inner edge of the pair of primary rails. Carts of successively decreasing width are adapted to roll on the outer edges and inner edges respectively of each successive pair of auxiliary rails. To prevent a cart from moving rearward of an adjacent wider cart, a lip may extend upwardly from the front of a cart to abut the adjacent upper cart. This system allows storage of five or more successive loads within a storage bay.
