摘要： A cast-in-place and lithographically shaped mobile, monolithic polymer element for fluid flow control in microfluidic devices and method of manufacture. Microfluid flow control devices, or microvalves that provide for control of fluid or ionic current flow can be made incorporating a cast-in-place, mobile monolithic polymer element, disposed within a microchannel, and driven by fluid pressure (either liquid or gas) against a retaining or sealing surface. The polymer elements are made by the application of lithographic methods to monomer mixtures formulated in such a way that the polymer will not bond to microchannel walls. The polymer elements can seal against pressures greater than 5000 psi, and have a response time on the order of milliseconds. By the use of energetic radiation it is possible to depolymerize selected regions of the polymer element to form shapes that cannot be produced by conventional lithographic patterning and would be impossible to machine.

摘要： A drive unit for a motor metering pump and a metering pump, including a drive chamber and a drive shaft arranged in the drive chamber. The drive shaft is rotated about a longitudinal axis in a direction of rotation during operation of the drive unit, the drive unit includes a bearing in which the drive shaft is mounted. The drive chamber is filled with a lubricant up to a filling level during operation of the drive unit, and the bearing is arranged above the filling level in the direction of the longitudinal axis. The drive shaft has a conveying channel for the lubricant, which extends from a first point below the filling level to a second point above the filling level and is arranged in such a way that, during operation of the drive unit, lubricant is transported from the first point to the second point.

摘要： A fluid flow meter is described, that includes intermeshing gears that may rotate synchronously. The fluid flow meter may produce a pulsed output that can be normalized to suitable values according to a method of normalizing input pulses generated in response to the rotation of gears. A volume counter can be incremented by an amount equal to a volume per input pulse each time an input pulse is generated. When the volume counter exceeds a first reference volume, a normalized output pulse can be generated until the volume counter exceeds a second reference volume.

摘要： The present invention provides apparatus for measuring volumetric or mass flow of fluid. The apparatus comprises a capsule that is adapted to move upwardly and downwardly within a housing and receive fluid from a tube. The apparatus further comprises force exerting means and preferably a magnetic means that is adapted to exert force on the capsule, the force is proportional to a position of the capsule within the housing. The force is measurable and controllable. A seal is provided in the capsule's bottom opening so as to fluidically block the capsule and a pin is provided so as to push aside the seal when the capsule is downwardly positioned and is filed with fluid so as to drain it. The number of times the capsule is drained in a predetermined time can be calculated so as to attain the volumetric flow rate of the fluid through the apparatus.

摘要： The fluid flow meter includes a flexible membrane formed of a flexible material and containing an apparatus for providing the membrane with resilience for undulation. The membrane is mounted in the fluid flow path such that the pair of faces simultaneously define with the housing fluid impermeable seals at least two different locations along the flow path. The membrane flexes so as to permit passage of discrete quanta of fluid, each having a known volume. The flow meter generates electrical signals corresponding to flexure of the membrane, and the electrical signals are monitored for determining a fluid flow rate.

摘要： A measuring device is provided for measuring a mass flow composed of bulk material, in particular grain, in a continuous, circulating conveyor enclosed in part by a housing, having planar conveyor elements, which conveys the bulk material from a lower bulk material receiving area to a higher bulk material delivery area. A substantially circular movement course is imposed on the bulk material delivered by the respective conveyor element in a substantially radial direction of an inner surface of a cover section of the housing by a guide surface formed in the upper region of the conveyor. The bulk material is deflectable toward a sensor surface of the measuring device. At least the sensor surface of the measuring device is disposed in the upper region of the conveyor such that there is a tangential course in the transition from the guide surface to the sensor surface.

The system includes an inlet, a main line comprising a line section, an outlet fluidically connected with the inlet via the main line, a displacement device arranged in the main line, a circuitous line which branches off the main line between the inlet and the displacement device and to enter the main line between the displacement device and the outlet, a pressure difference transducer arranged in the circuitous line, an evaluation and control unit which controls the displacement device, and a bypass line comprising a pump and a sensor. The bypass line branches off from the main line or from the circuitous line and ends at a same side of the displacement device and the pressure difference transducer to bypass the line section or the circuitous line from which the bypass line branches off.
