Magnetic means to control the angle are claimed. Methods and apparatus include sequential steps that utilize one or more orbiting abrasive surfaces together with an abrasive disk sharpener where in each step there is a guide, preferably magnetic, to control the sharpening angle and where the angle is progressively greater in those sharpening steps where the orbiting abrasive elements are employed. Also claimed are means in a disk sharpener to prevent accidental contact of the face of the blade with the moving abrasive surface.

Abstract: A viability test device wherein the viability of a test composition for the determination of an analyte of interest can be determined by simply wetting the device with ordinary water. The viability device can be prepared in three formats: a control or calibrator device, an internal control device and a self indicating device. Unreacted analyte, or an analog thereof, can be incorporated in a limited defined portion of a dried carrier matrix incorporated with a test composition to provide an internal control test device. When wetted with water, a positive optical response, usually color, indicates the test composition can provide a viable test for the analyte. The internal control test device is particularly advantageously used by diabetics in their own homes where a negative test response could be due to the desired control of the user's condition or due to deterioration of a test composition because of unfavourable storage conditions.

Abstract: A flushable electrochemical reference cell (10) is disclosed, in which clogging of junctions of the cell by contaminants can be prevented or minimized. The cell incorporates a triple junction (22,24,26) design with dual, independently operative flushing systems (28,32;34,38). The first flushing system (28;32) flushes the interior of the first junction (22) and the exterior of the second junction (24), and the second flushing system (34,38) flushes the interior of the second junction (24) and the exterior of the third junction (26). When the cell (10) is used in-line on a chemical process stream, pressure equalizing means (40) are employed between the stream and the standard electrode, of which the third junction (26) is an element. Elevation of the exits (30,36) of the flushing systems (28,32;34,38) above the junctions (22,24,26) releases air from the cell which may collect at the junctions and impair the accuracy of the readings.
