Patent CA-2288420-C (CA)
Title: Gas incinerator
Inventor: MOTYKA DANIEL R
IPC: F23L3/00
Filed: 1999-11-03
Granted: 2007-05-01
Abstract: There is provided a gas incinerator having a combustion chamber above a lower chamber and communicating therewith. Combustion air flows into the lower chamber, thence upwardly toward the combustion chamber.    Vanes are provided in the lower chamber, to impart a rotational movement to the air as it rises toward the combustion chamber. Nozzles are located toward the bottom of the combustion chamber for injecting the fuel, in the form of gas, into the combustion chamber so as to cause the injected gas to rotate oppositely to the air rotation, in order to provide substantial turbulence and mixing. The injection direction of the gas also lies substantially parallel with a hypothetical plane transverse to the axis of the cyclonic movement of air, thus avoiding an axial component in the injection direction of the gas, and therefore minimizing the expulsion of gas, air and combustion products from the combustion chamber.

Title: Loop allocation for optimizing compilers
Inventor: BLAINEY ROBERT JAMES
IPC: G06F9/45
Filed: 1999-11-08
Granted: 2004-05-11
Abstract: Loop allocation for optimizing compilers includes the generation of a program dependence graph for a source code segment. Control dependence graph representations of the nested loops, from innermost to outermost, are generated and data dependence graph representations are generated for each level of nested loop as constrained by the control dependence graph. An interference graph is generated with the nodes of the data dependence graph. Weights are generated for the edges of the interference graph reflecting the affinity between statements represented by the nodes joined by the edges. Nodes in the interference graph are given weights reflecting resource usage by the statements associated with the nodes. The interference graph is partitioned using a profitability test based on the weights of edges and nodes and on a correctness test based on the reachability of nodes in the data dependence graph. Code is emitted based on the partitioned interference graph.

Title: Bandpass reactive collision cell
Inventor: BARANOV VLADIMIR I
IPC: H01J49/42
Filed: 1998-06-02
Granted: 2004-08-10
Abstract: A method of reducing isobaric interferences by transmitting ions from an ion source through an ion transmission device, typically a quadrupole collision cell, and then into an analyzing mass spectrometer, in which the collision cell is operated with a pass band which rejects intermediate ions which would otherwise tend to react to form isobaric interferences. Preferably ammonia is used as a reaction gas in the collision cell. Depending on the chemistry involved, the collision cell may be operated to set the low mass cutoff at an appropriate level, or more usually, the pass band will have both high and low mass cutoffs determined by applying both RF and DC to the collision cell. The collision cell may also be operated with a pass band to transmit ions into a time-of-flight (TOF) mass spectrometer, thus limiting the mass range of ions entering the TOF and thereby improving the duty cycle of the TOF.

Filed: 2000-02-04
Granted: 2006-04-11
Abstract: A communication line not affected by natural and artificial obstructing objects is established between mobile objects and stationary stations surrounded by such obstructing objects. Economical artificial satellite service capable of efficiently performing satellite broadcast, mobile satellite communication, satellite-to-satellite communication and earth surveillance is provided by constructing the system with a small number of satellites using the communication line. Six orbital elements of a plurality of artificial satellites at a reference time are determined, and a plurality of elliptical orbits corresponding to the determined six orbital elements are combined. Each of the satellites is then appropriately arranged on each of the orbits to form a group of artificial satellites. Satellite communication or satellite broadcast is performed using the group of artificial satellites.

Patent CA-2305793-C (CA)
Inventor: ECKHARD CHRISTIAN
IPC: A62B33/00
Filed: 1999-07-30
Granted: 2004-10-19
Abstract: Search devices fitted with only one send and receive antenna do not enable buried persons to be found in a quick and reliable manner because the strongest signals can only be detected at extremely short distances when the antennae of the transmitter and reception devices are placed in a parallel position. The invention uses four antennae in order to pinpoint the exact position of the transmitter, especially at a clue distance. The four antennae form two pairs of antennae placed at a specific angle to each other. The pairs of antennae are respectively comprised of two antennae that are also placed at a specific angle to each other. The direction of the field line of the send antenna can be detected by comparing the signal intensities of the antenna pairs. Lateral deviations and forward or rear deviations from the shortest distance point can be recognised by comparing the signal intenisties of the corresponding antennae. All signals have the same intensity at this point. Search devices are mainly used by wilderness skiers and those choosing to ski off piste.

Title: Gas turbine aeroengine control system
Inventor: MURAMATSU HIRONORI
IPC: F02C9/00
Filed: 2000-07-28
Granted: 2003-11-18
Abstract: In a control system for a gas turbine aero engine, without using the engine inlet sensors, the engine inlet condition data including the intake air temperature and the intake air pressure is estimated based at least on the detected rotational speed of the turbine, the detected inlet pressure of the turbine and the detected atmospheric pressure, etc. through reasoning. Thus, the system can remove the engine inlet sensors (which are generally expensive) and instead, enables to estimate the engine inlet condition data necessary for controlling the engine with a relatively simple configuration.

Abstract: A network node of a SONET ring is provided with a tributary line interface that receives packets from LAN users. A packet switch performs a switching operation on the LAN packets. An aggregate line interface establishes an STM path on a communication link and a number of packet paths within the STM path. An STM switch connects the packet switch between the tributary line interface and the aggregate line interface so that the switched packets are transported over the packet paths. Monitoring circuitry monitors the LAN packets and produces a warning signal if an abnormal condition is detected in one of the packet paths and transmits the warning signal to the communication link. Preferably, the monitoring circuitry is provided in the tributary line interface.
