Title: A turbo-charged internal combustion engine with in-cylinder egr and injection rate shaping
Inventor: SUDER TIMOTHY ANDREW
IPC: F01L9/20
Filed: 2003-02-27
Abstract: A turbo-charged internal combustion cylinder assembly includes a combustion chamber which may be communicably connected to a compressor via an intake port through an intake manifold and aftercooler so the compressor may provide pre-combustion gases to the combustion chamber when the intake valve is open. An exhaust port communicably connects the combustion chamber to an exhaust manifold. An exhaust valve may open to exhaust post-combustion gases to the exhaust manifold while an intake valve is substantially closed, and the exhaust valve may open to admit post-combustion gases to the combustion chamber while the intake valve is substantially open and an exhaust port pressure in the exhaust port is higher than a combustion chamber pressure in the combustion chamber. A fuel injector may admit fuel to the combustion chamber. A spill valve may control a rate of fuel injection to the combustion chamber, the spill valve having a first position providing a maximum fuel injection rate, a second position providing a substantially zero fuel injection rate, and at least one intermediate position providing an intermediate fuel injection rate between the maximum fuel injection rate and the zero fuel injection rate.

Inventor: PAUL JAMES ROBERT
IPC: A47C13/00
Filed: 2003-04-23
Abstract: A modular furniture unit is disclosed. The furniture unit includes a base which is capable of releasably securing various furniture modules. The base frame has walls with a plurality of slots for accommodating the insertion of tongue portions extending from the furniture modules. The slots are accessed through the base's cover by means which allow the cover to be opened and sealed at various locations. The cover is opened in selected locations to allow insertion of the tongue portions into the slots, but is otherwise sealed to hide the unused slots. The furniture modules can be easily and conveniently removed and repositioned allowing the units to be reconfigured. The tongue portions may be retained in the slots by a downwardly angled relationship between the slots and the tongue portions.

Title: Retractable debarking apparatus
Inventor: POROPAT MICHAEL
IPC: B27L1/00
Filed: 2003-05-01
Abstract: A retractable debarking block for a debarker having an enclosure to receive logs for debarking in order to vary the aggressiveness of the debarking process. The block member has a debarking surface with projecting teeth and is positionable within the enclosure of the debarker to be movable between a retracted position in which the debarking surface does not contact logs in the enclosure and an exposed position in which the debarking surface is exposed to engage logs. The block member is fittable into a rotor or drum type debarker. An actuator is provided to move the debarking surface between the retracted and exposed positions. The actuator is adapted to permit automatic movement of the debarking surface toward the retracted position if the force exerted by the logs exceeds a pre-set limit to prevent damage to the blocks and the logs. Preferably, the actuator is an airbag or telescoping cylinder operable over a range of pressures to permit adjustment of the pre-set limit. Alternatively, the actuator may be a spring that moves the block member to the extended position by default.

IPC: G01V1/02
Filed: 2001-10-26
Abstract: A method for identifying optimal seismic energy source configurations for a selected seismic survey area. Physical properties of the surface or near-surface soil or rock are assessed and are tested to determine the response of such soil to energy source characteristics and geometries. A test model for a source is generated and is projected to create a far-field seismic response model. A seismic event is initiated within the survey area to measure seismic data, and such measured data is compared against the far-field seismic response model. Differences can be assessed to permit modifications to the model, and the model can be tested for different types and configurations of seismic source energy sources.

IPC: A61F2/90
Filed: 2001-12-21
Abstract: A braided stent (10) includes coiled distal and proximal anchors (21), (22) adapted to be disposed in the kidney and bladder, respectively. The stent is threaded onto an elongate member which is advanced distally to position the stent through the ureter. The stent may be releasably coupled to a guidewire (34) and advanced distally by a tubular positioner (30) threaded over the guidewire. Retracting the guidewire into the positioner releases the stent and completes deployment. The stent may include a distal nosepiece (121) which may be inserted through a side port and nto a first lumen tube (123). A road (138) in the first lumen is advanced forward to engage the nose piece and thus move the stent distally. Retraction of the rod disengages the stent and thus completes deployment. A second lumen in the tube receives a guidewire which may be moved independently of the rod and stent.

Title: Multi-sample fermentor and method of using same
Inventor: MCMULLAN DANIEL TERENCE
IPC: B01L99/00
Filed: 2002-02-08
Abstract: A fermentation apparatus is described to produce known and repeatable amount of untainted fermentation product using multiple fermentation vessels. To facilitate compatible processing with other processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame (Figure 14). The container frame is configured to hold the sample vessels during fermentation and transport of the vessel array to, or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because of its design, this fermentation apparatus is applicable for simultaneous optimization of a number of process parameters (e.g., cell growth rates).

Patent CA-2446829-A1 (CA)
Inventor: MAYER YARON
IPC: B01D1/16
Filed: 2003-10-27
Abstract: Many areas in the world already suffer shortages of water, and others will suffer from it in the coming years. Therefore more efficient water sweetening is essential for our survival on this planet. The most commonly used water sweetening methods are: Reversed osmosis, distillation, electrodyalisis, and partial freezing. However, these methods suffer from low efficiency and high energy consumption, thus making them significantly more expensive than naturally obtained water. The present invention describes a system & method for efficient and low energy sweetening of water, based on borderline fast fluctuation between liquid to gaseous state and back, by using centrifugal forces to make water droplets fly at a high speed, so that they evaporate for a split second, the salt is separated, and they condense again. The present invention tries to make the process energy-efficient by enabling the use of lower speeds and smaller droplet sizes and solving various problems involved with that, while preferably using a parabolic plate with a preferably vertical axis of rotation. Other solutions covered are for example automatically collecting the salt particles into larger molecules, for example by the use of Chelating agents, so that the larger molecules can be removed for example by magnetic forces or with a larger-hole sieve that requires considerably less energy than reverse osmosis.
