Patent CA-2362881-C (CA)
Inventor: NOBLE STEPHEN DUNCAN
IPC: F02M21/02
Filed: 2001-11-30
Granted: 2004-01-27
Abstract: This invention relates to an apparatus for pressurizing a fluid and delivering a gas comprising a pump, an accumulator and a heater such that the pump pressurizes a quantity fluid received from a fluid store and delivers that pressurized fluid to an accumulator. The accumulator then delivers a quantity of the pressurized fluid to a heater that, in turn, warms the fluid to a gas within a specified temperature and pressure range to be delivered to the end user as required. The invention further relates to a method of delivering a gas at a desired pressure and temperature wherein a quantity of fluid is received, pressurized and stored as a fluid in an accumulator storage vessel at a desired pressure. The fluid is then delivered from the accumulator to a heater where it is warmed and delivered to the end user as a gas at specified temperature and pressure.

Title: A control method for copper density in a solder dipping bath
Inventor: NISHIMURA TETSURO
IPC: B23K1/00
Filed: 2001-02-23
Granted: 2011-04-05
Abstract: This method controls a copper density in a dip solder bath holding a molten solder alloy containing at least copper as an essential composition thereof during a dip soldering step of one of a printed circuit board with a surfaced copper foil and a component part having a copper lead attached thereto. The method includes a step of introducing a replenished solder containing no copper at all or a copper content having a density lower than that of the molten solder in the bath prior to the supply of the replenished solder to the bath so that the copper density in the bath is controlled to a predetermined constant density or lower. The molten solder alloy in the bath contains tin, copper, and nickel as the major compositions thereof, and the replenished solder contains nickel and balanced tin, for example. Alternatively, the molten solder alloy in the bath contains tin, copper, and silver as the major components thereof, and the replenished solder contains silver and balanced tin. The copper density of the molten solder in the bath is controlled to less than 0.85 weight % at a solder temperature of about 255 ~C.

Title: Method for regional system wide optimal signal timing for traffic control based on wireless phone networks
Inventor: MYR DAVID
IPC: G08G1/08
Filed: 2002-07-05
Granted: 2010-09-21
Abstract: A method for the system wide control of signals in a traffic network in real time to provide an overall reduction in congestion is described. In the method, signals obtained from vehicular-based cellular phones provide location information on moving vehicles and are input into an Intelligent Traffic Control System to provide position information that is stored in the form of records. Mathematical models use those records together with detailed digital maps and algorithms to compute actual travel times consumed by traveling along road sections, by queuing near signalized intersections, and by making various allowed turns and go-throughs in the vicinity of signalized intersection areas. The actual travel times measured for a fixed control time period are compared to the corresponding theoretical travel times and form a basis for a mathematical optimization model. Maximization of that model allows computation of adjusted phase timings for signalized intersections within a given area to optimize vehicular flows for the next control period.

IPC: H04W4/16
Filed: 2002-07-25
Granted: 2006-03-21
Abstract: In a multimedia communications system (100), a conference establishment server coordinates the scheduling of a conference call. The server receives request for conference calls (202). The request includes a list of participants and may include an indication of the resources necessary and any rules for the conference call. The request may indicate critical resources or participants that are required for the call. Based on the request, the server determines a conference time and notifies participants of the time (204, 206, 210). Prior to conference time, participants are reminded of the time and automatically connected to the call. The server may check the status of users on the telecommunications network to determine availability. If a critical participant or resource is unavailable at conference time, the conference may be cancelled with notification to the participants.

IPC: C04B28/02

Granted: 2014-04-01
Abstract: Concrete's durability to freeze-thaw cycles is dependent on its level of air entrainment, the appropriate level of which is achieved with the aid of surface active or air entraining agents. These agents promote the fragmentation of large air voids into smaller ones and stabilize air voids in the concrete. The carbon matter found in fly ash when used as a pozzolanic component of concrete, adsorbs the air entraining agents, reduces the air voids and concrete's ability to withstand many freeze- thaw cycles. This invention teaches a process for a partial removal of the carbon from the coal ash, used in concrete, through a partial combustion of only a fine carbon fraction of the carbon residue of the coal ash responsible for adsorbing the air entraining agents, in a reactor with a controlled ignition system. The process of the invention thus limits the adsorption of the air entraining agents and improves the freeze-thaw properties of the concrete produced.

Abstract: L'invention concerne un laser d'émission par la surface à cavité verticale (VCSEL) ayant une région de bande interdite (PBG) photonique formée dans, ou contiguë à un premier et/ou à un second miroir, ou dans une couche d'espacement placée entre une région de gain et au moins un miroir. La région PBG a une périodicité prédéterminée qui empêche sensiblement la lumière produite de se propager dans la région et définit un orifice de passage de lumière sans la périodicité de façon à permettre à la lumière produite de se propager par ledit orifice. La région PBG ne traverse pas la région de gain, ce qui permet d'utiliser la région de gain entière et de réguler l'efficacité de l'effet laser en supprimant ou en empêchant cet effet laser dans certains modes sans pertes, plutôt que d'interdire les modes. L'énergie dégagée des modes interdits est en fin de compte couplée au(x) mode(s) autorisé(s). L'invention concerne une séparation du confinement de la région de gain et de la commande de mode sans introduction de pertes d'énergie.
