Abstract: This invention provides devices, compositions and methods for determining the concentration of one or more metabolites or analytes in a biological sample, including cells, tissues, organs, organisms, and biological fluids. In particular, this invention provides materials, apparatuses, and methods for several non-invasive techniques for the determination of in vivo blood glucose concentration levels based upon the in vivo measurement of one or more biologically active molecules found in skin.

Abstract: An apparatus for correcting an initial measurement of the concentration of a first water soluble species dissolved in a water-based component of a biological fluid that also includes a second water soluble species and a volume occupying component, the initial measurement having been taken using an original sample of the fluid that had been diluted by an amount of additional aqueous solution to form a diluted sample is disclosed; the concentration of the second water soluble species is measured in an undiluted sample of the biological fluid to obtain a direct concentration and is measured using a diluted sample of the fluid to obtain an indirect concentration, and the initial measurement of concentration of the first species is adjusted based on a combination of the direct and indirect concentration determination of the second species.

Abstract: A replaceable insert cutter comprising a cutting body, a plurality of insert pockets in the periphery of the body, each pocket having an insert back locating wall establishing insert circumferential position, a V-shaped support seat establishing a radial and axial position of the insert in a radial threaded screw hole extending through from the V support seat, a cutter insert mounted in the pocket having a back surface engaging the back locating wall, a V base of the insert seated on the support seat, a screw hole and screw extending radially through the insert and retaining engagement with the threaded screw hole, and a radially outermost cutting edge facing circumferentially away from the back surface.

Abstract: Hematocrit level of a blood sample is measured by flowing the sample along a liquid flow path and using electrodes in the flow path to obtain electrical signals representative of the sample's electrical conductivity and of the concentration of an ion species in the path, either before or after the sample measurement. Electrical signals are obtained for standardizing solution conductivity and ion species concentration. A tentative sample hematocrit value is derived from the sample and standardizing conductivity signals. Then the tentative hematocrit value is corrected with reference to the sample and standardizing ion concentration signals and to the known standardizing solution ion concentration value. A control solution of the ion species at known concentration is used for evaluating the hematocrit detection apparatus; the solution also includes an ion activity enhancing agent.

Abstract: A method of making bags of the automatic or self-opening satchel-bottom type having an outer sheet of paper and a plastic inner liner in which a tab portion is formed with a portion of the inner liner removed so that when the bag bottom is formed a paper surface of the tab portion can be adhered to a paper portion of a diamond fold when the bag bottom is completed.

Abstract: A threading tool is disclosed featuring the combined utilization of a multi-toothed thread chaser insert with a single point indexable thread chaser insert. In generating a desired thread form, successive teeth of the multi-toothed chaser perform the initial cutting passes on a workpiece, while the tooth of the single tooth chaser performs the final finishing cutting operation.

Abstract: A transducer unit which includes a backing member formulated from a water activated ceramic to which is added a powdered metal.
