Patent CA-2358662-A1 (CA)
Inventor: CHEN JAMES
IPC: A61K41/00
Filed: 2000-01-14
Abstract: The present invention is drawn to methods and compositions useful for targeting and treating target tissues affected by or involved in metabolic bone disorders and bone metastases with photodynamic therapy (PDT) in a mammalian subject. The compositions are bisphosphonates, pyrophosphates or bisphosphonate-like compounds conjugated to photosensitive agents which are optionally further conjugated to ligands which are target tissue specific antibodies, peptides or polymers. The methods of PDT treatment utilize these  compositions to target the tissues or cells of a mammalian subject to be treated. The methods comprise irradiating at least a portion of the subject with light at a wavelength absorbed by said photosensitizing agent that unde r conditions of activation during photodynamic therapy using a relatively low fluence rate, but an overall high total fluence dose results in minimal collateral tissue damage.

Title: Method and apparatus for treating leach fields
Inventor: POTTS DAVID A
IPC: C02F3/02
Filed: 2000-03-16
Abstract: The functioning of the leach field (40) of a septic tank (20) type sewage system is maintained or rejuvenated by flowing air or other active gas into the system's conduits (34, 56), for instance, leaching chambers or perforated pipes in stone filled trenches. Differential pressure created by an air mover (71) forces air or other active gas to flow through the soil (38) adjacent the conduits (34), to an extent sufficient to push water from any saturated soil and engender desirable aerobic biochemical conditions in the soil. In alternate embodiments, conduits may be pressurized or evacuated. Valves (70) and other plumbing (68) are provided to control air flow and enable continued function of the sewage system during air flow treatment. Auxiliary piping is buried adjacent the trenches of the leach field and pressurized or evacuated to cause air flow through the soil and or the conduits of the leach field.

Title: Engine protecting apparatus for vehicle
Inventor: ITO NOBUYASU
IPC: F02D17/00
Filed: 2001-11-09
Abstract: A vehicle having a power assist device and an engine protecting apparatus is capable of steering and braking after any abnormality of the engine is detected. The engine protecting apparatus includes a battery, a key switch, a condition switch, a timer and a timer-operative switch. The battery supplies an electric current to the ignition circuit of the engine.      The key switch is disposed between the battery and the ignition circuit and has an ignition terminal. The condition switch turns on and off based on engine conditions. The condition switch is connected to the ignition terminal of the key switch. The timer is connected to the ignition terminal of the key switch and has a predetermined period of time. The timer measures a time period from when the condition switch is turned on. The timer-operative switch is actuated by the timer. The timer-operative switch interrupts the electric current flowing to the ignition circuit when the timer measures the predetermined time period. Therefore, the engine continues to run for a while even after an engine abnormality is detected.

Title: Agencement de preaccentuation mettant en oeuvre des melangeurs dans des applications electro-optiques non lineaires
Inventor: KRASULICK STEPHEN BRADLEY
IPC: H03F1/32
Filed: 2000-03-29
Abstract: L'invention concerne un agencement de préaccentuation, destiné à l'utilisation d'un signal d'entrée pour entraîner un dispositif non linéaire comportant une entrée de commande. D'abord, des premiers moyens échantillonnent une portion du signal d'entrée, puis la portion échantillonnée est introduite au niveau d'au moins un trajet de préaccentuation comprenant un mélangeur sensible à la portion échantillonnée du signal d'entrée, de manière à produire au moins des produits d'intermodulation du second ordre du signal d'entrée, lesquels produits sont conditionnés. Des moyens de combinaison combinent les produits d'intermodulation du second ordre, conditionnés, avec le signal d'entrée échantillonné, de manière à produire un signal préaccentué compensé pour une distorsion du second ordre servant à exciter l'entrée de commande du dispositif non linéaire. Dans un aspect de l'invention, les moyens d'échantillonnage et ceux de combinaison peuvent être fournis par des circuits résistifs. L'utilisation de tels circuits élimine le recours à des coupleurs directifs incorporant des composants magnétiques. En conséquence, cet agencement de préaccentuation comprenant le mélangeur et les circuits résistifs peut se présenter sous la forme d'un circuit intégré.

Title: Sootblower nozzle assembly with an improved downstream nozzle
Inventor: KELLER DAVID L
IPC: F28G1/16
Filed: 2002-01-08
Abstract: The present invention discloses a new design of the nozzle and the lance tube of a sootblower to clean the interior of a heat exchanger by impingement of a jet of cleaning medium. In accordance with the teachings of the present invention the sootblower design developed, incorporates a nozzle at the tip of the distal end of the lance tube (downstream nozzle). The lance tube also includes an upstream nozzle positioned opposite and longitudinally apart the distal end nozzle. This design allows for the flow of the cleaning medium to enter into the inlet end of the nozzle without coming to a haft at the end of the lance tube. Further, the present invention also provides for a converging channel to be disposed in the interior of the lance tube to direct the flow of cleaning medium passing the upstream nozzle into the inlet end of the downstream nozzle with minimal hydraulic losses and flow maldistribution. The present invention also discloses an airfoil body to be placed around the upstream nozzle to minimize the flow disturbances caused by the bluff body of the converging channel.

Patent CA-2369805-A1 (CA)
Inventor: DZIAWA MICHAEL
IPC: H01M8/02
Filed: 2002-01-31
Abstract: This disclosure describes a Network Synchronization Architecture, which allows the synchronization hardware component to be co-located with the Optical Network Interface component. This architecture is used to provide network timing for a Network Element (NE) such as a BLC (Broadband Loop Carrier System). A Broadband Loop Carrier system is similar in functionality to a DLC (Digital Loop Carrier), the primary difference being the ability to provide some form of high speed data service such as ADSL (asymmetric digital subscriber loop). To accommodate this network timing architecture, the NE provides redundant timing paths between the combined Optical Network Interface/Synchronization Units of which there are two for each system. A control function monitors the hardware and signal conditions to maintain functionality in the presence of hardware faults or input signal faults.

Title: Animal carcase analysis
Inventor: BENN ALAN
IPC: G06T7/60
Filed: 2000-09-20
Abstract: The process for analysing an ovine animal carcase comprises capturing an ima ge of a dorsal view to generate colour image data for the carcase (10). Predetermined anatomical points (21 - 24) of the carcase are identified to then derive dimensional measurements for the carcase. Also characterising parameters such as yield and fat depth of the carcase are derived by processing colour data included in the captured image data in conjunction wi th the derived dimensional measurements. The colour data processed are the colo ur data for predetermined selected surface areas, especially the chump, the loi n and the shoulder areas (30 - 32) of the carcase (10) known or determined to have a significant correlation to the characterising parameter related to fatness. Desirably the tail (17) of the animal carcase is identified and its  width determined since this is useful as a variable in a carcase yield predictive equation. The colour data comprises average RGB values representi ng red, green and blue colour components which are intensity normalised colour values.
