Title: Centrifuge clutch and blade design with control mechanism
Inventor: BEATTEY JEFFERY N
IPC: B04B11/04
Filed: 1999-06-02
Abstract: An improved centrifuge having a clutch mechanism (120) with a shifting coupling (122) which provides a positive lock for synchronous blade (170) and bowl (185) rotation during processing.  The scraper blades (310, 320, 330, 340) have recesses (314, 324, 334, 344) for inserts (315, 316, 325, 326, 335, 336, 345, 346) permitting a variable cutting edge geometry and the mixing and matching of cutting edge geometry while using the same base blade (300). The centrifuge has a tangential outlet (507) and an annular housing (502) to minimize spray and misting in the exiting centrifuged liquid. The centrifuge has a plurality of blades (610, 620, 630, 640, 710, 720) with radially overlapping edges (614, 624, 534, 644, 714, 724) to keep the fluid being centrifuged compartmentalized and thus quiet for maximum efficiency. The scraping assembly blades (610, 620, 630, 640) are angled (617, 627, 637, 647) in the scraping direction to force the solids towards the exit of the centrifuge. A  programmable logic controller monitors the load on the drive motor (207) to determine flow rate of injected fluid and/or to ascertain whether any dysfunction is occurring and to take appropriate steps to correct malfunction.

Title: Adhesion promotion
Inventor: LEACH ROGER JOHN
IPC: B05D7/00
Filed: 1999-10-08
Abstract: Adhesion of a thermosetting powder coating to a glass substrate surface using a silane adhesion promoter, is enhanced by modifying the pH of the glass surface to between 3.5 and 5, prior to, or during, the action of the promoter. The pH-modification may be effected during washing of the surface prior to spray-application of the promoter, or by including an acid or alkali modifier in the silane solution.  Alternatively, the silane, or the silane and the modifier, may be included in the thermosetting powder to become active during fusing of the powder to the glass surface. An acid or alkali solution dried on the surface prior to application of the promoter for activation with the promoter on heating, may be used instead or in addition.

Title: Biological individual sampler
Inventor: KENNING VANESSA M
IPC: G01N1/34
Filed: 2001-05-23
Abstract: A portable sampling unit capable of separating particulates, including biological organisms, from gaseous fluids such as air. A combined particle impact collector and fan is used to both move fluid through the sampling unit and to collect particulates. In one embodiment, the combined particle impact collector is a disposable unit that is removed and replaced with a fresh unit after each sampling period. The disposable unit is placed in a rinse station, where a liquid sample is extracted for later analysis. Alternatively, a disposable detection unit is incorporated in the sampling unit to provide real time detection of chemical toxins and/or biological pathogens. Preferably, the detector unit includes micro-fluidic channels so that a minimum amount of sample and test reagents are required. In another embodiment, the combined impact collector is integral to the sampling unit, rather than a separate disposable item.

Patent CA-2354804-A1 (CA)
Title: Method and solid phase calibration sample for calibration of analytical instruments
Inventor: GOLEDZINOWSKI MACIEJ
IPC: G01N27/64
Filed: 2001-08-07
Abstract: A method and a solid phase calibrant are provided suitable for use by untrained personnel to calibrate an analytical instrument under field conditions away from a laboratory. Filter discs or other suitable substrates are impregnated, by the process of adsorption, with solutions of known concentrations of analytes and chromatographic phase materials, such as polymers, in suitable solvents. The substrate material is selected to be chemically inert and to riot negatively interact with the analytes, the calibration process, or the analytical instrumentation. The polymers cause the analyte to adhere to the substrate until the solution is desorbed by heating, so that the impregnated substrates farm stable calibration solutions in solid phase which can be easily and reliably stored, transported, and used by operators with minimal training. The substrate is preferably contained in a card holder which can be easily inserted into and preferably mate with an inlet for the analytical instrument. Within the instrument, the solid phase calibrant is desorbed by heating the substrate to release a standardized amount of analyte calibrant into the instrument. The calibration technique is particularly suitable for ion mobility spectrometers which detect explosive or narcotic materials.

Title: Noise monitoring system
Inventor: FUKUDA EIJI
IPC: G01V1/22
Filed: 2001-11-16
Abstract: To transmit an actual sound (noise) when the noise level becomes higher than a regulation standard.      In each noise detecting unit 1, the level of noise is measured through a microphone 5 and a noise meter 6 and input into a radio set 7. At the same time, an actual sound as the noise is input through a microphone 8 and a microphone amplifier 9 into a PHS 10. In a noise monitoring unit 2, a PC 14 communicates with the radio set 7 in each noise detecting unit 1 through a radio set 13 to input the noise level measured by each noise detecting unit 1. The PC 14 determines whether or not the noise level is higher than a regulation standard. If the noise level is higher than the regulation standard, the PC 14 requests a PHS 15 to call the PHS 10 in the specified noise detecting unit 1 to establish the communication between the PHS 15 and the PHS 10. At this time, a maintenance worker 4 can hear the actual sound from the PHS 15. Further, the actual sound is recorded by an MD recorder 16.

Patent CA-2374113-A1 (CA)
Inventor: BURGERMEISTER ROBERT
IPC: A61F2/90
Filed: 2002-03-01
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent.      Finally, a new method is disclosed for making scents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process.      Further embodiments provide living hinge connectors and connections along the length of the radial strut member.
