Patent CA-2472663-A1 (CA)
Inventor: BETCHER TRAVIS P
IPC: E04G21/32
Filed: 2004-06-25
Abstract: A reusable concrete anchor strap includes a strap having a first end, a second end, a middle portion, and an intermediate portion. The fast end and the second end are proximate a connector end and the middle portion forms a first loop member proximate an anchor end. The intermediate portion is a first segment between the first end and the middle portion and a second segment between the second end and the middle portion. A securement member secures and interconnects the foal segment and the second segment to form a second loop member thereby allowing for reuse of the strap when the fast loop member is disconnected to create a second anchor end proximate the second loop member. The first loop member and the second loop member are configured and arranged to engage at least one anchor member of a concrete structure.

Title: Capping board with separating walls
Inventor: DUFRESNE ROBERT P
IPC: C25D17/12
Filed: 2004-06-29
Abstract: Disclosed in a capping board for use to support hanging legs of anodes and cathodes within adjacent electrolytic cells. This capping board has a main body having a bottom surface shaped to fit onto upper edges of the adjacent cells, and a top surface. A first set of spaced part insulating blocks project from the top surface. This first set of blocks extends in line all over the length of the capping board on one side of the main body. A. second set of spaced part insulating blocks also projects from the top surface. This second set of blocks also extends in line all over the length of the capping board at a given lateral distance from the first set of blocks. Thus, the two sets of blocks form two rows that together define a central path on the top surface. Each of the blocks has a recess forming an upwardly and laterally opening compartment to receive and support one of the hanging legs of the anodes and cathodes. Advantageously, a plurality of separating walls project upwardly from the top surface of the main body so as to extend transversally across the central path and dividing this central path into a plurality of separate segments in which separate contact bars may respectively be positioned. Due to such a division of the contact bars into separate segments, any short circuit that occurs by accident is no more "transferred" to all the electrodes of the cells. It is actually transmitted only to the few electrodes in contact with the segments) to which is connected the electrode that is at the origin of the trouble.

Title: Method of and apparatus for cleaning runoff water
Inventor: MEYERMANN AUSTIN
IPC: B01D21/00
Filed: 2004-10-20
Abstract: Runoff water from parking lots and filling stations is cleaned by first passing it via an inlet pipe tangentally into a vortex chamber where the swirling action helps to separate the contaminants from the water. Floating contaminants are stored in the vortex chamber, trapped at the top of the chamber by the roof of that chamber and at the lower part of the chamber by a skirt which is part of the chamber and extends downwardly for a limited distance from the inlet pipe. That roof has an access opening to permit removal of the floating contaminants, The body o~ the fluid thereafter moves downward into a settling chamber where heavier-than-water contaminants settle to the bottom where they can be removed during regular cleaning. As the fluid in the settling chamber builds up it passes through clearing screens to a clean water outlet. A by-pass overflow pipe to process very large volumes of water extends upward from the settling chamber and ultimately feeds the outlet pipe. Each screen may have louvers projecting from the screen for preventing contaminants from blocking the screen.

Patent CA-2502895-A1 (CA)
Inventor: SPILKA DAVID G
IPC: A61F2/06
Filed: 2003-10-15
Abstract: A stent compression method for particular use in pre-surgical securing and conforming of a vascular stent upon an angioplasty balloon. One variation of the stent compression method comprises inflating an agioplasty balloon inside a vascular stent in order to secure the vascular stent upon the balloon;  applying uniform compression pressure around the balloon/stent unit; and adjusting the internal balloon pressure and the compression pressure so that the balloon/stent unit is compressed. A pressure chamber with an elastic cylindrical membrane mounted inside the chamber may be used to provide the compression pressure. The inflated balloon provides the balancing pressure from inside the stent. The maintenance of internal balloon pressure during the stent compression process may provide uniform distribution of pressure along the stent and even radial compression rate around the circumferential surface of the stent.
