Patent CA-2260377-A1 (CA)
Inventor: JAMES CLIVE A
IPC: F04F5/54
Filed: 1999-01-25
Abstract: An automatic system for draining the water out of a boat, consisting of a rigid tube clamped in a vertical position to the anti-cavitation plate on an outboard motor or outdrive. The discharge end of the tube sits below water level behind the propeller. A flexible tube is connected to the infeed end of the rigid tube and it is connected to the discharge end of a pressure release valve that is clamped to the transom. A flexible tube is connected to the infeed end of the pressure release valve and the infeed end of this tube sits on the interior bottom of the boat.      When the boat is in forward operation, the rapid flow of water generated by the action of the propeller reduces the pressure of the water outside the tube (Bernoulli's Law) and the since the water in the tube is at a higher pressure, it flows out the discharge end, drawing water out of the boat. This may also be refered to as a venturi effect. The pressure release valve prevents water from being siphoned back into the boat when the boat is not in forward operation.

Patent CA-2280249-A1 (CA)
Inventor: SAVARD PIERRE
IPC: A61K33/24
Filed: 1999-08-12
Abstract: This invention describes the use of vanadium compounds as anti-angiogenic s. Biperoxovanadium compounds are preferred since they are more potent than the  "oxo" compounds and less toxic than the latter. Anti-angiogenic activity has been verified in vitro against human umbilical vascular endothelial cells as well as ex ovo i n the chicken chorioallantoic assay membrane. The vanadium compounds also inhibit the endothelin plasmatic increase after insulin stimulation in rats. It is proposed that vanadium compounds are valuable therapeutically active anti-angiogenics by acting int er alia either on the proliferation of endothelial cells, or the secretion of endothelins, or both.
Patent CA-2281254-A1 (CA)
Title: Method and apparatus for eliminating background interference signals from multichannel detector arrays
Inventor: SIMOLA JUHA
IPC: G01R33/035
Filed: 1999-08-27
Abstract: A method and apparatus is described for making multichannel measurements of weak signals in noisy environments. The method is based on an adaptive compensation technique in which the large interfering background signal is first recorded by using the apparatus itself. By a statistical analysis of this multichannel measurement the independent components of the interference are determined. The apparatus is provided with compensator elements which are properly coupled to individual sensors for both to collect and distribute information on the interference during the measurement. The proper couplings are derived from the interference measurement mentioned above. In this way the output of the device can be made immune to the large amplitude interference components present in its environment. This reduces the dynamic range requirement for the data transport and storage systems.

Title: Railcar load tie-down belt winding and storage apparatus
Inventor: LITTLE HEWARD CECIL
IPC: B60P7/08
Filed: 1999-09-13
Abstract: A belt winding and storage compartment is fixed to an outward facing railcar surface. An aperture is provided in a front wall portion of the compartment. A belt winder is removably insertable through the front wall aperture to coil at least a portion of the belt inside the compartment. The belt winder incorporates first and second rods which are fixed at a right angle. A spaced-apart pair of belt-receiving members are fixed to and extend outwardly from an upper end of the first rod, parallel to the second rod and in a direction opposite to the direction at which the second rod extends relative to the first rod. In one embodiment, an aperture is provided in the railcar surface, in alignment with the front wall aperture. The aligned apertures rotatably support opposed ends of the belt-receiving members as the belt is coiled inside the compartment. In an alternative embodiment, a belt winder support and belt guide plate is fixed to the outward facing railcar surface. An aperture is provided in the plate in alignment with the front wall aperture. The aligned apertures rotatably support opposed ends of the belt-receiving members as the belt is coiled inside the compartment. The belt winder support and belt guide plate is preferably spaced apart from an opposed front wall portion of the compartment by a distance which is just sufficient to accommodate a width dimension of the belt between the belt winder support and belt guide plate and the front wall portion. This prevents the belt edges becoming jammed against the front wall and/or railcar surface.      Preferably, the compartment has a removable cover to prevent penetration of water, snow or ice inside the compartment.
