Title: Method and apparatus for controlling traffic flows in a packet-switched network in order to guarantee service performance
Inventor: DAVIS TOM
IPC: H04L47/21
Filed: 1998-02-12
Abstract: A scheduling device for use in a packet-switched network, belonging to the class of non-work conserving or idling weighted round robin (WRR) arbiters, assigns a new connection N new slots in a fixed-length repeating scheduling frame by selecting free slots which are close to idealized slots that would, if assigned, eliminate fitter or cell delay variation. The scheduler is able to simultaneously determine if a new constant bit rate connection requiring a predetermined bandwidth conforms to a leaky bucket or GCRA algorithm characterized by a peak packet or cell emission interval T=1/PCR and a packet or cell delay variation time, CDVT, i.e., whether the new connection is GCRA (T, CDVT) conformant. This determination is made by comparing the quantity ME + ML against the CDVT, where ME is a time equivalent to the maximum number of slots by which any assigned slot is earlier than a corresponding ideal slot and ML is a time equivalent to the maximum number of slots by which any assigned slot is later than a corresponding ideal slot. The scheduler can thus also carry out connection admission control (CAC) functions in an ATM  network switch.

Abstract: Procédé servant à déterminer l'activité d'une enzyme de polymérisation de nucléotide dans un spécimen et mise en application de ce procédé afin de déterminer l'activité d'ADN polymérase de HIV 1 RT et Herpes Simplex. On capture cette enzyme au moyen d'un anticorps monoclonal immobilisé sur un support solide et capable de fixer l'enzyme sans exercer d'effet négatif sur son activité. On retire les contaminants et les facteurs de perturbation et la polymérisation du nucléotide commence par l'apport d'une solution de réaction contenant un produit de recombinaison composé d'une amorce et d'un gabarit, ainsi qu'un substrat de nucléotide, les conditions de la réaction étant sélectionnées de façon à promouvoir l'association permanente entre les produits de recombinaison anticorps-enzyme et amorce-gabarit. Si nécessaire, on effectue le lavage du substrat de nucléotide, du produit de recombinaison amorce-gabarit et de la solution réactionnelle, afin de les éloigner du polymère venant d'être synthétisé et on détermine la quantité de nucléotide qui a été incorporée dans le polymère, ce qui permet de déterminer l'activité de l'enzyme.

Inventor: RAITH ALEX KRISTER
IPC: H04B1/16
Filed: 1996-10-18
Abstract: A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.

Patent CA-2251836-A1 (CA)
Title: Valve timing system
Inventor: ROBERTS FREDERICK WILLIAM
IPC: F01L13/00
Filed: 1997-04-16
Abstract: A variable valve timing system applicable for vary the opening and closing cycle of the inlet and outlet valves of an internal combustion engine. The system comprises a cam follower (4) and a cam (1) which is rotated about the cam shaft (3) to move the valve between its open and closed position. To vary the cycle of the opening and closing of the valves, a rotational means (11 and 12) is connected to the cam follower (4) to rotate the cam follower (4) such that the cam follower (4) and cam (1) are out of alignment such that the cam lobe engages the contact surface (2) at a higher point and hence earlier than if the cam follower (4) and the cam (1) are aligned. Therefore the valve is opened sooner and closed later, increasing the degrees of cycle for which the valve is open, for example, as the engine revolutions increase.

Title: Method for minimizing hydrogen halide corrosion in a partial oxidation process
Inventor: WINTER JOHN DUCKETT
IPC: C01B9/00
Filed: 1997-07-14
Abstract: The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone (14) of the gasifier (10). The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The salt-free water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations.
