20080209943 | Setting for gemstones, particularly diamonds - A novel setting for a gemstone including a girdle, a crown on one side of the girdle, and a pavilion on the opposite side of the girdle, characterized in that the setting mounts the gemstone in an inverted orientation by prongs received in grooves formed in the crown of the gemstone such that the pavilion faces outwardly of the setting and the crown faces inwardly of the setting. Such a mounting is particularly useful when mounting a plurality of gemstones contiguously, in which case the prongs mounting each gemstone are concealed by the girdles of the gemstones. One embodiment is described wherein a plurality of gemstones are all mounted in the inverted orientation with the pavilions facing outwardly, and another embodiment is described wherein alternate gemstones are mounted in the inverted orientation with the pavilions facing outwardly, and with the remaining gemstone being mounted in the normal orientation with the crowns facing outwardly. | 09-04-2008 |

20090049926 | Triple Redundancy Vortex Flowmeter System - A system includes a first shedder that is at least partially disposed in a fluid conduit and that generates vortices within the fluid conduit, a first flow sensor system that is responsive to the vortices generated by the first shedder and a second flow sensor system that is responsive to the vortices generated by the first shedder. The system further includes a second shedder that is at least partially disposed in the fluid conduit, that generates vortices within the fluid conduit, and that is separated from the first shedder by a distance. A third flow sensor system is responsive to the vortices generated by the second shedder. | 02-26-2009 |
20100307220 | FLOWMETER CALIBRATION TECHNIQUES - Descriptions are provided for implementing flowmeter zeroing techniques. In operating a flowmeter, it may be the case that, if not properly calibrated, the flowmeter will produce erroneous measurements, e.g., will indicate a non-zero flow during a period of zero flow. By determining a magnitude of such erroneous measurements, calibration values may be determined, which may later be used to adjust a measurement that is output by the flowmeter and thereby improve an accuracy of the flowmeter. Such calibration values may be determined for a plurality of operational conditions associated with the flowmeter, such as densities of materials being measured, and/or configurations of flow elements associated with transporting material to the flowmeter. Then, the calibration values may be correlated with the relevant operational conditions, and stored for later use. In this way, during an actual operation of the flowmeter, a number of calibration values may be made available, and an optimal calibration value may be selected for an existing operational condition of the flowmeter. | 12-09-2010 |
20110005337 | SINGLE AND MULTIPHASE FLUID MEASUREMENTS - A first property of a process fluid is measured using a differential pressure flowmeter. A second property of the process fluid is measured using a Coriolis flowmeter. A third property of the process fluid is determined based on the measured first property and the measured second property. | 01-13-2011 |
20110016984 | Multiphase Coriolis Flowmeter - A flowmeter is disclosed. The flowmeter includes a vibratable flowtube, and a driver connected to the flowtube that is operable to impart motion to the flowtube. A sensor is connected to the flowtube and is operable to sense the motion of the flowtube and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to determine a first flow rate of a first phase within a two-phase flow through the flowtube and determine a second flow rate of a second phase within the two-phase flow. | 01-27-2011 |
20110016988 | MULTI-PHASE CORIOLIS FLOWMETER - A flowmeter is disclosed. The flowmeter includes a vibratable flowtube, and a driver connected to the flowtube that is operable to impart motion to the flowtube. A sensor is connected to the flowtube and is operable to sense the motion of the flowtube and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to determine an individual flow rate of each phase within a multi-phase flow through the flowtube. | 01-27-2011 |
20160123781 | SPLIT FLOW VORTEX FLOWMETER - A vortex flowmeter has first and second process connections with a meter inlet and outlet, respectively, therein. The first and second process connections are configured to connect, respectively, to upstream and downstream segments of a fluid pipeline. A fluid conveyance system conveys fluid from the inlet to the outlet and divides the fluid into separate fluid streams that flow through separate passages. Each of the passages has its own vortex metering unit configured to generate and detect vortices in the respective fluid stream. A processing system is configured to calculate a sum of the flow rates through all of the fluid streams. | 05-05-2016 |
