Title: Method and system for measuring performance for computing electronic exchange and agreement of data
Inventor: WALSH CHRISTOPHER J
IPC: G06Q50/18
Filed: 2001-03-30
Abstract: A process for managing financial transactions involves defining the process as a series of steps that involve the transfer of information needed by each party to settle the transaction. A system for measuring the performance of participants in the management process tracks the information transferred between the parties and records the date and time that the information is transferred. Periodically, information including the date and time information is processed and used to determine measures of performance over the period.  These measures of performance can include the amount of time between the completion of any of the steps in the management process, for example, from the time when transaction was initiated (e.g. a trade is executed) to the time the information to be transmitted to or received by any of the participants to the management process or the management system in any of the steps of the management process. The performance information can be compiled into predefined reports which allow a party to compare and rank the performance of counterparties with which the party had completed transactions.
Patent CA-2405273-A1 (CA)
Title: Methods and device for percutaneous remote endarterectomy
Inventor: DEMARAIS DENISE M
IPC: A61F2/958
Filed: 2001-04-09
Abstract: The present invention provides devices, systems, methods and kits for the percutaneous removal of unwanted tissue or obstructive matter from body cavities or lumens, particularly from the vasculature. Blood vessels, including the coronary, peripheral and neurovascular circulation, which are narrowed or blocked by atheromatous material or plaque are often treated with traditional endarterectomy procedures. The present invention allows the benefits of such a procedure with an intraluminal approach, particularly a percutaneous approach. Generally, the present invention provides a set of catheters or tools which are percutaneously introduceable to the site of the blockage or occlusion. The tools dissect or cut through the innermost tissue layer of the lumen to an underlying tissue layer. The innermost tissue layer is then stripped away from the underlying layer with the occlusive material thereattached. The detached tissue layer and occlusive material is then removed from the lumen; this may include additional cutting, maceration and removal through mechanical aspiration. In any case, the resulting lumen is free of obstruction.

Patent CA-2421462-A1 (CA)
Inventor: LEFCORT MALCOLM D
IPC: F23N3/00
Filed: 2003-03-10
Abstract: In a two-stage wet waste burner, a first-stage combustion chamber has a symmetrical grate arrangement. The grate comprises spaced individual upright air supply tubes with flat horizontal upper surfaces swept by ash-removal plates. The height and width of the air supply tubes are selected to provide an upper surface profile approximating the natural angle of repose of the waste. Twin waste feed distribution augers span the chamber and rotate in mating troughs. The axis of rotation of each auger is sloped so that the discharge end of the auger is higher than the feed inlet end, and the trough sidewalls are inclined downwardly from the inlet end to the discharge end; these attributes promote even discharge of waste across the span of the chamber. Vertical walls of the air supply tubes are provided with air ports for supplying combustion air; the vertical orientation of the apertures and a degree of shielding of the upper surfaces of the air supply tubes inhibit clogging of the air ports. Drivers for the ash-removal plates comprise pendular arms each pivoting about an upper pivot point lying substantially in the vertical plane of symmetry, each arm being pivotally connected directly or indirectly to the ash removers. A burner of the foregoing type may be combined with a dryer for drying a portion of the waste and with a mixer that mixes dried waste with raw wet waste and feeds the mixed waste to the burner. The mixed waste can be efficiently burned yet can be efficiently conveyed. Such combination is particularly suitable for combustion of sewage sludge.
