Patent CA-2312102-A1 (CA)
Title: Integrated fluid manipulation cartridge
Inventor: CHRISTEL LEE ALLAN
IPC: C12M1/33
Filed: 1998-12-24
Abstract: A cartridge (101) for separating a desired analyte from a fluid sample includes a sample port (103) and a sample flow path extending from the port through the body of the cartridge. The sample flow path includes at least one flow-through component (122), e.g., filter paper or a microfabricated chip, for capturing the desired analyte from the sample as the sample flows through the cartridge. The cartridge also includes an elution flow path for carrying elution fluid through the component (122) to release captured analyte from the component into the elution fluid. The elution flow path diverges from the sample flow path after passing through the component (122). Flow controllers (41 A  and 41B) direct the remaining fluid sample into a waste chamber (139) after the sample flows through the component (122) and direct the elution fluid and eluted analyte into a reagent chamber (141) and reaction chamber (143). The continuous-flow design of the cartridge permits the rapid processing of a fluid sample that is larger in volume than any interactive region within the cartridge, allowing increased sensitivity in the detection of low copy concentrations of analytes, such as nucleic acid.
Patent CA-2314535-A1 (CA)
Inventor: MEHNERT DAVID WEBB
IPC: A23C19/028
Filed: 2000-07-25
Abstract: In accordance with the method of the present invention, dried grated Parmesan cheese particles are manufactured from milk. The fat level of the milk is standardized to about 2.0 percent. The milk is subjected to membrane processing by ultrafiltration and diafiltration to provide a retentate. The retentate is then fermented with a combination of lactic acid cultures, a flavor culture, and a lipase enzyme.  The fermentation is carried out at a temperature between about 90 and about 120°F. The fermented retentate is then evaporated to a solids level desired in the finished dry grated Parmesan cheese, which is generally in the range of from about 18 to about 24 percent moisture. A clotting agent is added to the fermented retentate immediately before the initiation of the evaporation step. Evaporation is preferably carried out in a drum drier under quiescent conditions. The Parmesan cheese is removed from the drum drier and is transferred to a disintegrator, such as a Fitz mill, to provide a grated Parmesan cheese product. The grated Parmesan cheese may be then blended with an anticaking material and an antimycotic material prior to packaging for consumer use without further aging or curing.

The data storage unit is reliably engaged on the flat support by means of a collar disposed close to a centering through hole of the storage unit. As a result, the central opening of the storage unit can be coupled, by forced fitting, with the through opening of the flat support.

Inventor: STEPANEK MICHAEL J
IPC: G03H1/30
Filed: 2000-10-23
Abstract: A cardboard support has an adhesive layer and a metallized holographic image, wherein the metallized holographic image includes at least two holograms, such that the first hologram is visible only by non-coherent light and the second hologram is visible only by coherent light. The holographic images are formed on a photosensitive element on a polymeric support by imaging steps, which include metallizing the holographic images and overcoating the holographic images with an adhesive layer. Next, the metallized holographic images are transferred to the cardboard by laminating the adhesive layer to the cardboard at a predetermined temperature and pressure, and subsequently delaminating the polymeric support from the cardboard, such that the holographic image remains on the polymer support for reuse.

Title: Bone repair composite material
Inventor: HEALY DAVID MICHAEL
IPC: A61L27/36
Filed: 1999-09-15
Abstract: There is provided an admixture comprising morsellised bone particles and particles of water-soluble biodegradable glass. The particle size distribution and diameter range is pre-selected to produce an aggregate.  Addition of the glass enables an admixture having aggregate characteristics and thus increased shear strength to be produced whilst simultaneously enabling bone regeneration to occur within the treated defect. The admixture is therefore useful in the repair of bone defects, especially primary joint arthroplasties, such as hip replacement operations.

Title: Transient bubble remediation in coriolis flowmeters
Inventor: DUTTON ROBERT E
IPC: G01F1/74
Filed: 1999-09-09
Abstract: A Coriolis flowmeter (5) is operable as a vibrating tube densitometer where a flow tube (103A-103B) is driven to vibrate at a fundamental frequency from which density of the material flowing through the flow tube (103A-103B) may be calculated. The drive gain is monitored as an indicator of multiphase flow including gas and liquid components where a substantial increase in drive gain indicates gas damping of the flowtube vibrations due to a transient bubble entering the flowtube. The gas damping effects of the transient bubble and the correspondingly reduced density readings are remediated by the use of historical density measurements corresponding to periods of flow when no transient bubble has entered the flowtube.

Title: Variable focus optical system
Inventor: IMRIE DAVID A
IPC: G02B15/06
Filed: 1999-09-13
Abstract: A variable focus optical system is particularly suitable for use in acquiring digital images for subsequent processing in a hand held, omnidirectional symbology or bar code reader (12) by which linear and two dimensional (matrix, maxi-code) bar codes (28; 34; 40; 52; 54) may be imaged over relatively long working distances. The imaging system includes a focusing objective taking lens (92) and a two-dimensional photodetector (93) that operate to form an image of an object such as a bar code in X and Y directions simultaneously and generates an electrical signal representative of the object or code for subsequent downstream processing. Focusing is achieved via a rotating disk (94) that carries a plurality of optical shims (130) or other light controlling surfaces to provide for different focus zones. A through-the-lens (TTL) targeting system is provided to visually assist the user in positioning the system for a variety of objects to assure that an object will be captured within the field of view and be sharply imaged on the photodetector (93) when the lens (92) is focused. Two different forms of artificial illumination are provided to accommodate nearby objects that may be either specular or partially diffuse and more distant objects where the reflection characteristics have less impact on image contrast. Ranging through the lens (92) using elements of the photodetector (93) is included to provide information to set the focus of the objective lens (92) in one of many possible focusing zones.
