Patent CA-2464586-A1 (CA)
Title: High throughput absolute flaw imaging
Inventor: GOLDFINE NEIL J
IPC: G01N27/82
Filed: 2004-04-16
Abstract: Apparatus and methods are described for the improved throughput and increased reliability for inspection of critical surfaces on aircraft engine disks. Eddy current sensor arrays allow two-dimensional images to be generated for detection of cracks in regions with fretting damage. Background variations due to fretting damage and stress variations are also accommodated. These arrays are combined with instrumentation that permits parallel data acquisition for each sensing element and rapid inspection rates. Inflatable support structures behind the sensor array improve sensor durability and reduce fixturing requirements for the inspection.

Patent CA-2475285-A1 (CA)
Inventor: PETIT KEVIN J
IPC: A62C33/00
Filed: 2004-07-19
Abstract: A stream shaper for reducing turbulent flow has a plurality of circumferentially-spaced vanes, with alternate vanes being axially-spaced from the remaining vanes. This axial separation of vane groups reduces the flow restriction caused by the vanes at any given cross section along the length of the stream shaper as compared to a stream shaper having the same total number of vanes extending the full length of the stream shaper. Axially spacing alternate vanes from the remaining vanes also permits a significant reduction in the overall length of the stream shaper while providing the turbulence reducing effects of a much longer stream shaper with vanes that extend uninterrupted the full length of the stream shaper.

Title: Lampe a consommation energetique reduite pour agriculture
Inventor: TREMBLAY FRANCOIS
IPC: A01G9/20
Filed: 2004-11-16
Abstract: Étant donné les problèmes environnementaux que l'on connaît aujourd'hui, beaucoup d'entreprises favorisent de plus en plus les technologies à faible consommation énergétique. De plus, le gouvernement encourage les entreprises en mettant à leur disposition des subventions pour l'obtention de technologies énergiquement économique. Par exemple, le milieu de l'agriculture en serre est une industrie énergivor e. Hydro Québec a effectué en août 2004 une demande à la régie de l'énergie pour le retrait du tarif « bi-énergie » dont la majorité des agriculteurs en serres bénéficient (voir en annexe le Richelieu agricole Vol. 8, NO 7, le 24 juillet 2004). Cela signifie pour eux le double du coût de l'électricité. Comment régler le problème de consommation d'énergie et quelle en est la source principale? Nous sommes venus à la conclusion que leur système d'éclairage consommait beaucoup trop d'énergie compte tenu de la proportion des spectres lumineux nécessaires à la photosynthèse. La solution: créer un éclairage sélectif émettant seulement les intervalles de spectres lumineux à haute intensité nécessaires à la photosynthèse. Utiliser deux types de led mono spectral en remplacement des ampoules. En comparaison, la quantité d'énergie consommée par le projet Soleil d'é té est de 250 watts pour une efficacité de 100%. Soit le 1/4 de l'énergie consommée par la 1000 watts au sodium.

Abstract: The operating frequency of a ballast is sufficiently far from resonance of a resonant tank circuit (430) that, when a compact fluorescent lamp (500) is dimmed to about one percent light output level, the ballast is operating wit h an open loop gain below a predetermined level, and is operating with an outp ut impedance greater than a predetermined and more preferably, greater than twi ce the absolute value of the maximum negative incremental impedance of the lamp . By changing the frequency to 85 kHz from 80 kHz through control circuit (418 ), for example, the gain is maintained about the same whether the light output is at five percent or one percent, for example.

Abstract: In accordance with this invention, there is provided a garden composter for decomposing garden waste in which the composter has a longitudinally extending cylindrical drum which is mounted to a support frame which is adapted to space the drum from a supporting surface. Tumbling means are provided for coupling the drum to the support frame for rotation of the drum relative to the support frame about an axis of rotation of the drum. The drum has at least two load openings formed in a cylindrical wall portion between two end wall portions and removable closure caps for selectively closing the load openings. At least one partition is provided in the drum to divide the drum into a number of chambers disposed side by side along the longitudinal axis. Each chamber communicates with a respective load opening. The partition has a fixed portion which is coupled to the drum and a relatively movable portion. Each portion has at least one flow control partition opening and the movable portion can be moved so that its associated flow control partition opening may be selectively brought into and out of registration with corresponding flow control partition openings in the fixed portion. In this way, the garden composter can receive organic waste through the load openings for decomposition in the chambers andthe waste can be aged selectively in the chambers to adjust its residence time before being discharged from the composter.</SD OAB>

Title: A polyester resin, a method of preparing the polyester resin, and a coating composition thereof
Inventor: RAMESH SWAMINATHAN
IPC: C09K23/00
Filed: 2005-01-26
Abstract: A polyester resin is the reaction product of plurality of a first compound and a plurality of a carboxylic acid anhydride. The first compound has hydroxyl groups. The carboxylic acid anhydrides react with the hydroxyl groups of the first compounds to form a plurality of first intermediate compounds. These first intermediate compounds have at least one hydroxyl group and carboxylic acid groups. A temperature of the first intermediate compounds is increased until the hydroxyl group of one first intermediate compound condenses with one of the carboxylic acid groups of another first intermediate compound. This condensing, or condensation, forms the polyester resin having an ester linkage and carboxylic acid groups. A second compound having at least one epoxy group and a carbamate compound can be subsequently reacted with the polyester resin. A  coating composition includes the polyester resin and a cross-linking agent reactive with the polyester resin.

Inventor: AMBROSE HARVEY
IPC: C05F17/00
Filed: 2005-02-25
Abstract: The process of the subject invention may be carried out by means of two or more vessels. The vessels are arranged in succession such that the outlet of one vessel is located above the inlet of the next vessel in succession. At the bottom of each vessel is a moving floor which causes the organic material to move from the feed end to the discharge end of the vessel.  Organic waste is fed into the first vessel and moves through each vessel in turn. As it moves from one vessel to the next it falls and as it does so it mixes and aerates. The process of the invention may also be carried out in a closed vessel having a number of compartments disposed end to end.  Organic waste enters the upstream compartment, travels downstream through each of said compartments in turn and discharges from said downstream compartment. The waste is agitated at the outlet of each compartment while being impelled into the next compartment in succession
