Abstract: A method and apparatus for fluid flow straightening and measurement introduces a high beta nozzle or venturi in-line with existing conduit. A fluid velocity measuring device is positioned in the throat of the high beta nozzle and measurements of velocity at multiple points in a plane perpendicular to the direction of fluid flow are taken. The velocity data points are then averaged and produce an output signal from which fluid flow rate can be determined.

Abstract: A method and device for sequencing at least a fragment of a linear polymer. The device comprises a well for placement of a rotaxane comprising the combination of a cyclic molecule and a linear polymer threaded through said cyclic molecule; a probe having the ability to move the linear polymer relative to the cyclic molecule while producing a signal resulting from the interaction of the cyclic molecule and a unit attached to the polymer; and means for reading said signal. The process comprises formation of the rotaxane, attachment of the probe, movement of the cyclic molecule relative to the linear polymer and the reading of signals. The device and method are especially useful for the sequencing of DNA.

Abstract: A flow meter for determining the flow rate or mass of a moving stream of fine particles comprises a guide means for guiding the material to be measured along a predetermined path having an entry end and an exit end. A transducer is operatively associated with one end of the guide means and includes a mechanical column connected between a load cell and the exit end of the guide means. The load cell produces an electrical output signal proportional to the flow rate of the material on the guide means. A means for vibrating the guide means is provided and serves to keep the flow stream moving and wherein the plane of vibration is perpendicular to the plane of measurement, thus eliminating measurement error due to the vibrational forces.

Abstract: A method and apparatus for detecting the presence of an impurity within a substantially spherical object, such as a pit within a piece of stone fruit as it passes through an inspection zone. An infrared point source light emitting diode positioned on one side of the inspection zone transmits a single light beam across the inspection zone.

An infrared filter is positioned between the lens and the CCD array. Thus, as the fruit passes through the inspection zone and is illuminated by the infrared light source and the intensity of the light transmitted through the fruit is received by the CCD array, a two-dimensional analyzable bit map representative of the cross-section of the object's density is produced.
