Patent CA-2523386-A1 (CA)
Inventor: FORD MICHAEL BRENT
IPC: B04C9/00
Filed: 2005-10-14
Abstract: A pumping apparatus and method incorporates at least one and preferably as many as four components that are configured to improve debris removal capabilities as compared to prior art apparatuses. The apparatus and method impart cyclonic motion to pumped fluid, in a manner that tends to separate entrained solids and other impurities, and further that helps draw solid impurities away from the pump barrel. In a preferred embodiment, a cyclonic effect first occurs in a seat plug having a funnel- shaped accumulator region leading to an interior passage therethrough, and at least one off-center opening extending from the interior passage to the exterior of the plug, In one embodiment, that effort is continued at a plunger adapter that has a plurali ty of inward-angled rings, and that also features off-center openings through whic h debris may pass to the interior of the plunger adapter. A top plunger adapter may also be provided, having angled veins and openings therethrough to impart cyclonic motion to the pump ed fluid as it exits the interior of the top plunger adapter. Finally, it may also be desired to provide a cage having angled veins, to continue the cyclonic effect on the fluid as it travels northward and into the pump barrel.

Title: Plasma arc torch
Inventor: GRIFFIN DAVID CHARLES
IPC: H05H1/32
Filed: 2006-01-25
Abstract: A plasma torch is provided having a movable member carrying an electrode and movable along a tubular member bore having a nozzle at one end. A piston member engaged with the movable member moves the electrode between inoperable and operable positions within the bore, the movable member being biased outwardly of the one end of the bore. A first sealing member engaged with the piston member allows a fluid flow into the bore to act on the piston member to move the electrode to the operable position when the nozzle/electrode is engaged with the tubular member. A second sealing member, engaged with the bore, engages the piston member when the nozzle/electrode is removed. The fluid flow enters the bore between the sealing members, the second sealing member thus preventing torch operation when the nozzle/electrode is removed by preventing the fluid flow from acting on the piston member.

Title: Frequency-independent spatial processing for wideband miso and mimo systems
Inventor: KETCHUM JOHN W
IPC: H04L27/26
Filed: 2004-08-17
Abstract: Frequency-independent eigensteering in MISO and MIMO systems are described.  For principal mode and multi-mode eigensteering, a correlation matrix is computed for a MIMO channel based on channel response matrices and decomposed to obtain NS frequency-independent steering vectors for NS spatial channels of the MIMO channel. ND data symbol streams are transmitted on ND best spatial channels using ND steering vectors, where for ND=1 for principal mode eigensteering and ND>1 for multi-mode eigensteering. For main path eigensteering, a data symbol stream is transmitted on the best spatial channel for the main propagation path (e.g., with the highest energy) of the MIMO  channel. For receiver eigensteering, a data symbol stream is steered toward a receive antenna based on a steering vector obtained for that receive antenna.  For all eigensteering schemes, a matched filter is derived for each receive antenna based on the steering vector(s) and channel response vectors for the receive antenna.

Title: Method and system for enhanced data searching
Inventor: MURUA ALEJANDRO
IPC: G06F40/00
Filed: 2004-02-12
Abstract: Methods and systems for syntactically indexing and searching data sets to achieve more accurate search results and for indexing and searching data sets using entity tags alone or in combination therewith are provided. Example embodiments provide a Syntactic Query Engine ("SQE") that parses, indexes, and stores a data set, as well as processes natural language queries subsequently submitted against the data set. The SQE comprises a Query Preprocessor, a Data Set Preprocessor, a Query Builder, a Data Set Indexer, an Enhanced Natural Language Parser ("ENLP"), a data set repository, and, in some embodiments, a user interface. After preprocessing the data set, the SQE parses the data set according to a variety of levels of parsing and determines as appropriate the entity tags and syntactic and grammatical roles of each term to generate enhanced data representations for each object in the data set. The SQE indexes and stores these enhanced data representations in the data set repository.  Upon subsequently receiving a query, the SQE parses the query also using a variety of parsing levels and searches the indexed stored data set to locate data that contains similar terms used in similar grammatical roles and/or with similar entity tag types as indicated by the query. In this manner, the SQE is able to achieve more contextually accurate search results more frequently than using traditional search engines.
