Patent CA-2236308-A1 (CA)
Title: Separator screen and screening method
Inventor: ROTH ELDON
IPC: A22C17/04
Filed: 1996-11-06
Abstract: A screen (12) for use in a separator device (10) includes an inner portion (22) opening onto the screen inner surface (24) and an outer portion (26) extending the re-mainder of the way through the screen material. The outer portion (26) of the screen opening (20) al-lows the desired material to pass therethrough, while blocking the entry of large pieces of hard ma-terial. The inner portion (22) of the screen opening (20) includes a deflecting surface (40) forming an acute deflecting angle (B) with the inner screen surface (24) in the direction at which a cutting ele-ment passes over the screen open-ing (20). Large pieces of hard material that may partially enter the screen opening (20) are pressed against the deflecting surface (40) as the cutting element passes over the screen opening (20), the deflect-ing surface (40) serving to deflect the hard material out of the screen opening (20) without chipping off or cutting off any of the hard mate-rial, which could then pass through the screen opening (20) along with the desired material.

Title: Blood heat exchange system employing micro-conduit
Inventor: HIER PETER J
IPC: A61M1/36
Filed: 1997-01-10
Abstract: Micro-conduit (102) with enhanced wetting characteristics for use in providing a blood heat exchanger apparatus (300) with improved heat exchange capability.

Title: Solid-liquid countercurrent extraction continuously separating apparatus
Inventor: NISHIZAWA HIDEYUKI
IPC: B01D15/02
Filed: 1998-03-02
Abstract: A row of (n + m) powder containers which contain powder for chromatography and a row of (n + m) solvent containers which contain solvent for partition are arranged closely in parallel to each other. 0): A predetermined quantity of sample solution is added to the m-th solvent container from the left. 1): The powder containers and the solvent containers of the same numbers from the left in the rows are coupled with each other to form a row of (n + m) pairs of the powder containers and the solvent containers. 2): The powder and solvent of each pair are mixed and stirred until components to be separated come into partition equilibrium. 3): The powder and solvent of each pair are separated and made to exist in the original containers of each pair. 4): The pairs are decoupled to form the row of the powder containers and the row of the solvent containers again, and the rows are shifted from each other by one container in the opposite directions alternately. The steps 1) -4) are repeated, completing one process composed of the steps 0) - 4) + steps 1) -4). The process is repeated. Each time the rows are shifted, the leading container containing separated sample component is removed, and a new container is added to the rear of the row to keep the number of containers in the row constant.  By this method, the samples can be separated by relatively small number of partition equilibrium steps.
