Patent CA-2267801-A1 (CA)
Title: Traffic hot spot locating method
Inventor: VAARA TOMI
IPC: H04W24/00
Filed: 1997-10-07
Abstract: The present invention relates to a method and an arrangement for determining a hot spot of telephone traffic in a cell. The invention uses simltaneously two basic measurements of digital radio systems: timing advance and adjacent cell measurement. Timing advance informs the distance (n0-n10) of the mobile station from the base station (BTS3) but not the direction. On the basis of the measured signal strengths of adjacent cells it is possible to determine a set of possible locations (T1, T2) of the mobile station when there is information about the coverage area of individual adjacent cells. When these measurements are used simultaneously, they exclude the inaccuracies of each other and enable very accurate location determination for monotoring traffic distribution. Timing advance is utilized to determine a set of circular, base-station-centric areas (n0-n10) and adjacent cell measurements are utilized to determine the direction of the mobile station to the base station (BTS3).
Patent CA-2267818-A1 (CA)
Title: Brayton or brayton-rankine combined cycle with hot-gas recirculation and inverse mixing ejector
Inventor: STANKOVIC BRANKO
IPC: F02C1/10
Filed: 1999-04-06
Abstract: An open/closed gas-turbine simple Brayton cycle or Brayton-Rankine gas- and steam-turbine combined-cycle power-producing system is disclosed, with the gas turbine recirculating a large portion of partly expanded high-temperature gas into an inverse mixing ejector. The inverse mixing ejector uses an injected-gas velocity that is necessarily greater than the jet-gas velocity to rise the hot-gas pressure up to the compressor-discharge level. This is a necessary condition for achieving very high cycle thermal efficiency. Maximum combined-cycle thermal efficiency can be expected to reach up to about 80%, that is, up to an appropriate temperature-level Carnot-cycle efficiency. The gas turbine cycle can operate in either simple-cycle, single-intercooled-cycle or multi-intercooled-cycle mode. The inverse mixing ejector can operate in either supersonic or subsonic regions of gas velocity; however for higher efficiencies supersonic velocities of injected and jet gas are recommended. For closed versions of the cycle, coal can be used as a fuel, as well as any other solid, liquid or gaseous fuel or waste material. Also, dry air or any other suitable gas, such as helium, can be used as a working gas-turbine fluid of a closed version of the cycle. High-temperature nuclear reactor cooled with helium (or any other suitable gas or gas mixture) can be used as a heat source for closed versions of the cycle. Open simple gas-turbine versions of the cycle are very suitable to be applied as highly effective aircraft engines. There are two possible configurations: (1) "MIXEJECT" in which hot recirculated partly expanded gas-turbine gas flows directly into the inverse mixing ejector, whereas at the outlet of the ejector there is a combustor (or any closed gas heater) for heating mixed gas up to a designed gas-turbine inlet temperature; and (2) "COMEJECT" in which hot recirculated partly expanded gas-turbine gas flows into the combustor (or any closed gas heater) for heating mixed gas up to a temperature higher than the designed gas-turbine inlet temperature, which is achieved at the outlet of the ejector by mixing with a stream of colder gas, compressed by a compressor. Both closed cycle configurations can be used without compressor. Instead of compressor, steam pressurized by a water pump can be mixed with a working gas in the inverse mixing ejector and expanded in the gas turbine. Exhaust gas would then be cooled in a high-temperature regenerator (or regenerative heat exchanger), heating both gas-turbine working gas and water/steam. These two fluids would be separated in an additional condenser, while water would then be pressurized by a pump. Corresponding cycle configurations are named "MIXEJECS" ("mixing ejector to combustion chamber - steam"  configuration) and "COMEJECS" ("combustion chamber to mixing ejector - steam" configuration).
Patent CA-2269976-A1 (CA)
Inventor: RUTZ RENE
IPC: B29B11/16
Filed: 1999-04-23
Abstract: The invention relates to a process for the manufacture of fibre-reinforced pressure vessels and the product produced therefrom. A vessel liner is wrapped with resin-impregnated fibres and cured according to conventional technology. The cured, fibre-wrapped liner is then subjected to elevated temperature and pressure over time. The elevation in temperature allows the resin to soften. The increased pressure imparts a tensile load in the fibres. The tensile load causes fibres to stretch and straighten in the resin. After cooling and when pressurised for duty, the now straightened fibres are capable of responding immediately to the tensile load and the burst strength of the vessel is increased as a result. The process can be combined with autofrettage in series or simultaneously to achieve even greater final strength.

Patent CA-2284418-A1 (CA)
Title: Arc fault circuit interrupter without dc supply
Inventor: MACBETH BRUCE F
IPC: H02H3/44
Filed: 1999-09-30
Abstract: Arcing faults are detected by sensing a voltage signal proportional to the rate of change, or di/dt, of the line current when the current steps into an arc fault. A current transformer is used to create the di/dt signal.  The transformer has a selected core type, number of windings, and size which saturates at a pre determined level of primary current. The saturation acts to clamp the maximum di/dt voltage signal at the transformer output, and produce a constant output voltage. The constant output voltage eliminates a signal with a high di/dt, which may occur during a lamp burnout, from producing a much larger di/dt signal than that caused by an arc fault at a lower level of step current. The di/dt signal is passed through a high pass filter, which attenuates 60hz sinusoidal signals, after which the signal is integrated. The integrator acts to delay circuit interruption means until a predetermined number of arcs has occurred. When the integrator voltage reaches a predetermined voltage level, a trigger device activates an electronic switch, which in turn activates circuit interrupting means. One of the novel aspects of this invention is the elimination of the need for a DC power supply.
