Patent CA-2134463-A1 (CA)
Inventor: LUOMA ROBERT P II
IPC: G01N33/49
Filed: 1993-04-23
Abstract: A method of partitioning a pre-selected phase of a sample of liquid having a plurality of phases of differing densities, and a tube. A sample of liquid is passed through a first end of a linear tube and into a first chamber of said tube. The first chamber is located at the first end of the tube and is separated from a second chamber located at a second opposed end of the tube by a separation device. The separation device slidably engages the interior surface of the tube in an essentially fluid-tight manner and has a flow-restriction orifice therein to permit fluid flow communication between the first and second chambers under the influence of force. The phases are then ordered within the tube using e.g.  axial centrifugation. The volume of the first chamber is reduced by movement of the separation device within the tube, such that one phase of the liquid in the first chamber flows through the flow-restriction orifice and into the second chamber.

Title: Molded partial pre-slit reseal
Inventor: GRABENKORT RICHARD W
IPC: A61J1/05
Filed: 1994-12-19
Abstract: This invention pertains to a reseal member made of a resilient material used for sealing a fluid access port.

Inventor: BERNARD JOHANNES GELEIJN
IPC: C22B19/04
Filed: 1995-06-07
Abstract: A method making pig iron employs an in-bath direct reduction performed in a metallurgical vessel which has above it a melting cyclone in which  iron-oxide-containing material fed thereinto is pre-reduced by hot reducing gas coming from the vessel.  Molten material passes downwardly from the melting cyclone into the vessel.  In order to recover zinc from a dust containing zinc and/or zinc oxide, the dust is fed into the melting cyclone.  Zinc is allowed to vaporize out of the dust into the hot gas in the melting cyclone.  The hot gas containing zinc is discharged from the melting cyclone, and zinc-containing material is extracted from this hot gas.

Patent CA-2159633-A1 (CA)
Inventor: GRAM ANKER
IPC: F04B19/06
Filed: 1994-03-29
Abstract: Cryogenic fluid piston pump functions as stationary dis-pensing pump, mobile vehicle fuel pump etc., and can pump vapour and liquid efficiently even at negative feed pressures, thus permitting pump location outside a liquid container. Piston in-ducts fluid by removing vapour from liquid in an inlet conduit faster than the liquid therein can vaporize by absorbing heat, and moves at essentially constant velocity throughout an induction stroke to generate an essentially steady state induction flow with negligible restriction of flow through an inlet port. Stroke dis-placement volume is at least two orders of magnitude greater than residual or dead volume remaining in cylinder during stroke changeover, and is greater than volume of inlet conduit. Cryo-genic tank has a liquid compartment, a vapour compartment, and inlet and overflow conduits. Inlet conduit receives liquid from dispensing pump and widely disperses liquid into liquid tank to contact and condense vapour. Overflow conduit restricts flow of excess liquid from liquid compartment to vapour compartment. Excess pressure in tank or temperature of overflow liquid from conduit is detected to automatically stop dispensing pump. As a fuel pump, the pump selectively receives cryogenic liquid and vapour from respective conduits communicating with tank, and pumps cryogenic liquid to satisfy relatively heavy fuel demand of engine, which, when satisfied, also pumps vapour to reduce vapour pressure in the tank while sometimes satisfying relatively lighter fuel demand.

Title: Method and apparatus for detecting surface features of translucent objects
Inventor: HECK RICHARD D
IPC: G01B11/28
Filed: 1995-09-06
Abstract: The topographic surface features of a translucent object, such as a citrus fruit with a peel, are scanned and evaluated to permit the classification thereof according to its surface features. In the case of citrus fruit, the coarseness or pebbliness, puff and crease, ridge and valley, cuts, punctures, scrapes and splits, clear rot or sour rot of the peel is optically identified through digital analysis of the pixel scans and sorted based upon the peel surface quality. The object is classified by separating the scanned image of the fruit from the background image and removing the background image. A statistical evaluation of the image of the object as a whole including both hemispheres of the object, is made to determine if there is any surface feature variation which might qualify as a defect or be a suitable basis upon which a classification judgement can be made. If there is, the object image is subject to high frequency or low pass filtering and thresholding of the pixel intensities to derive a refined image. The refined image is then tabulated or organized into neighborhoods contiguous to sharp transitions or gradual transitions to identify specific areas defined as blobs which, when compared against a given minimum area, shape requirement and/or width can be identified as one of the surface imperfections sought.
