Patent CA-2422723-A1 (CA)
Inventor: SMITH GEORGE A
IPC: C11D1/22
Filed: 2001-09-19
Abstract: This invention is directed to detergent compositions which employ sulfonated  alkyltoluenes as surfactants, wherein the sulfonated alkyltoluenes have a higher content of the sulfonated 2-phenyl alkyltoluenes isomers than was previously available in sulfonated alkyltoluene surfactants of the prior art . Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonate d alkyltoluenes having lower contents of the 2-phenyl alkyltoluene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkyltoluenes are also provided, including dry cleaning formulations containing same. The alkyltoluenes of this invention may be combined with alkylbenzene surfactants in order to provide detergent blends having increased water hardness tolerance, lower Krafft temperature, and increased cleaning performance over what was previously afforded by the prio r art.

Title: Square bale feeder attachment for flat-bed vehicles
Inventor: HEINIGER CEDRIC C
IPC: A01D90/08
Filed: 2003-03-31
Abstract: A preferred embodiment of a bed assembly for flat bed trucks has a square bale retriever at the rear of the flat bed that includes a pair of lift arms adapted to grasp a bale by its opposite ends and lift it up off the ground and onto a transverse feeder located at the front of the bed. Once deposited on the feeder, a pusher engages one end of the bale and pushes the bale along the feeder to progressively advance successive flakes of the bale into a discharging position off the remote end of the feeder. The bale can thus be progressively distributed one flake at a time, the frequency of flake discharge being controlled by the operator in the cab of the truck. Alternative embodiments for pushers for engaging and advancing the bale toward the discharge point are disclosed. The feeder may be utilized separate from the bed assembly and includes a ramp that causes the bale to move up an incline during feeding operations.

Abstract: La présente invention concerne un procédé qui permet d'inhiber, de stimuler, de moduler ou de réguler la réabsorption du glutamate. Dans ce procédé, on utilise des composés qui sont des ligands des récepteurs de glutamate, y compris de nombreux agonistes ou antagonistes des récepteurs de glutamate. On a remarqué que ces composés peuvent se lier aux vecteurs de glutamate ou bien peuvent moduler ces derniers et affecter les taux de glutamate extracellulaire en altérant l'activité des vecteurs. Les composés selon l'invention peuvent produire divers effets sur l'activité du vecteur de glutamate, y compris l'activation ou l'inhibition. Ces composés sont utiles pour traiter diverses maladies et troubles neurologiques impliquant l'activation des vecteurs de glutamate ou des récepteurs de glutamate. Par exemple, une quantité excessive de glutamate extracellulaire est une cause d'une activation excessive des récepteurs de glutamate. La stimulation de la réabsorption du glutamate par des vecteurs de glutamate peut améliorer l'activation excessive des récepteurs de glutamate au moyen de la réduction de la teneur en glutamate extracellulaire. Des formes de précurseurs de médicaments des composés de vecteurs peuvent être utilisées en tant que médicaments.
Patent CA-2431732-A1 (CA)
Inventor: STEFANOIU DAN CONSTANTIN
IPC: F28F3/02
Filed: 2003-06-11
Abstract: A turbulizer is formed that has corrugations that each have side walls with openings and offset portions in them.      A strip is rolled longitudinally to form a corrugated strip that has longitudinally extending corrugations. Openings and the above-mentioned offset portions are formed in the corrugated strip. This allows turbulizers to be formed with increased length dimensions as compared with conventional methods, without requiring complex and expensive equipment. A fin or turbulizer for a heat exchanger has a strip that has longitudinally extending side edges and longitudinally extending corrugations.      There are openings through the corrugations in a region that is intermediate the side edges. An imperforate side edge portion extends between the side edge and the intermediate region. The corrugations extend in a general plane. The imperforate side edge portion inclines with respect to that general plane outwardly away from the intermediate region. The side edge portion may incline with respect to the general plane outwardly away from the intermediate portion and may have a distal portion extending inwardly generally toward the intermediate portion. These arrangements permit increased heat exchange efficiency in use, while avoiding problems of defects, leaks, or of a heat exchanger assembly becoming propped apart in the event of increased width of the fin or turbulizer, for example because of tolerances in the starting materials.

Title: Technique for communicating concierge-type information to users of an information assistance service
Inventor: TIMMONS TIMOTHY A
IPC: G06Q10/06
Filed: 2003-07-04
Abstract: Telephone users desiring concierge-type services may connect via standard telephone procedures to a directory assistance provider, such as an operator or voice server. For example, the users may communicate to the provider a concierge-type service request for making a restaurant reservation. The provider may process the request in real time through an on-line reservation system (ORS) or off-line. In processing the request off-line, a pool of fulfillment agents may engage in such action as necessary to fulfill the request.      Information concerning fulfillment of the request, e.g., a reservation confirmation, may be provided to a user offline, even sometimes in the case of real time request processing.      Such information may be recorded in the form of a voice mail, transmitted through a virtual network to a voice mail system, which may be maintained by the telephone carrier to which the user subscribes. The user in a conventional manner is prompted by the voice mail system to access the voice mail to learn the recorded information.

Title: Adaptive model-based control systems and methods for controlling a gas turbine
Inventor: BRUNELL BRENT JEROME
IPC: F02C9/28
Filed: 2003-09-04
Abstract: Adaptive model-based control systems and methods are described so that performance and/or operability of a gas turbine (51) in an aircraft engine, power plant, marine propulsion, or industrial application can be optimized under normal, deteriorated, faulted, failed and/or damaged operation. First, a model (52) of each relevant system or component is created, and the model (52) is adapted to the engine (51 ).  Then, if/when deterioration, a fault, a failure or some kind of damage to an engine component or system is detected, that information is input to the model-based control (54) as changes to the model, constraints, objective function, or other control parameters. With all the information about the engine condition, and state and directives on the control goals in terms of an objective function and constraints, the control then solves an optimization so the optimal control action can be determined and taken. This model (52) and control (54) may be updated in real-time to account for engine-to-engine variation, deterioration, damage, faults and/or failures using optimal corrective control action command(s).

Abstract: An optical network system having a global controller capable of controlling all the elements of the network. The controller receives performance data from each optical network element and calculates a performance value for each channel transmitting through the system. The controller then isolates the channel with the minimum performance value and tests possible changes in network element parameters to find a change which would increase this performance value. Once such a change is found, it is implemented and the system is reoptimized.
