Patent CA-2736589-A1 (CA)
Inventor: FANG ZHIGANG ZAK
IPC: C22C29/08
Filed: 2009-10-28
Abstract: A method for manufactur-ing functionally graded cemented tungsten carbide with hard and wear-resistant sur-face and tough core is described. The said functionally graded cemented tungsten car-bide (WC-Co) has a surface layer having a reduced amount of cobalt. Such a hard sur-face and tough core structure is an example of functionally graded materials in which mechanical properties are optimized by the unique combination of wear-resistance and toughness. WC-Co with reduced-cobalt surface layer may be fabricated through a carburization heat treatment process fol-lowing conventional liquid phase sintering.  The graded WC-Co thus obtained contains no brittle .eta. phase.

Title: Foreground region extraction program, foreground region extraction apparatus and foreground region extraction method
Inventor: ONAI RIKIO
IPC: G06T7/00
Filed: 2009-09-17
Abstract: Foreground and background pixels designated by a user are used as reference pixels. Ones of three-dimensional divided color spaces to which the reference pixels belong are used as reference divided color spaces. The color distance between each of the reference pixels and a respective one of adjacent pixels is calculated, and further it is determined whether the adjacent pixels belong to the reference divided color spaces. The costs of the adjacent pixels are calculated based on the foregoing calculated color distances and also based on the weighting based on the determination of belongingness to the reference divided color spaces. One of the adjacent pixels exhibiting the smallest cost is defined as a foreground or background pixel. The color distance calculation, the determination of belongingness, the cost calculation and the definition are repeated with the defined adjacent pixel used as a reference pixel, thereby extracting a foreground area from an image at a high speed.

IPC: A61B17/064
Filed: 2009-10-07
Abstract: A system for the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular tissue each fixed by a retaining clip is described. The system includes four devices to achieve such percutaneous direct plication annuloplasty.  The first is a prolapsable crossing catheter. Second, a deflecting guide catheter is used to provide a means for guiding the plication device into proper position at the subvalvular region of the mitral valve annulus. The plication device is then used to make placations in the subvalvular region of the mitral valve annulus. Fourth, a formable linear retainer clip is deployed by the plication device in order to retain the plicated tissue in the plicated form. The formable linear retainer is formed into a reverse "C" clip by the jaws of the plication device acting in conjunction with a retainer pusher.

Title: Oil isolation and decontamination apparatus
Inventor: BILHETE LOUIS
IPC: B03B9/02
Filed: 2009-09-11
Abstract: There is provided a portable oil isolation and decontamination system comprising a plurality of high heat energy generators that supply high heat energy to an oil isolation and decontamination unit. Each heat energy generator comprises a chamber for gasifying used rubber tires, waste oil, coal or other combustible materials for the production of volatile gases and high energy heat. The oil extractor unit comprises a pair of parallel, elongate rotating cylinders that each rotate within a common closed housing. Oil-rich material such as oilsands, oilshale, contaminated soil or used oil is introduced into one end of each rotating cylinder and is caused to migrate to the opposite end in cascading fashion as the cylinder rotates. High energy heat from the generators is directed at the rotating cylinders to indirectly heat the oil-rich material therein to vaporize the hydrocarbons as the rotating drum migrates the oil-rich material towards its collection end. Vacuum pressure withdraws the vaporized hydrocarbons from the cylinder, and the cleaned sand or other solid material exits the collection end of each rotating cylinder and housing. The vaporized hydrocarbons condense and are collected within a forced-air condenser for recycling. An optional second stage refrigeration unit condenses any residual vaporized hydrocarbons that may be missed by the forced-air condenser.
