The intermediate ring is positioned between the measuring membrane and the platform; the active hard solder, or braze, is heated in a soldering, or brazing, process, wherein the intermediate ring remains essentially solid during the soldering, or brazing, process. | 10-10-2013 |
| 20130305829 | METHOD FOR CONDITION MONITORING OF HYDRAULIC ACCUMULATORS - The invention relates to a method of condition-monitoring hydraulic accumulators. The gas content of the accumulators is monitored by the gas volume being calculated on the basis of the weight and working pressure of the accumulators. The working pressure of the accumulators and a relevant operational history are recorded with an electronic logging system which stores data for use in connection with condition-based maintenance of the accumulators. | 11-21-2013 |
| 20140060198 | Combination Static and Dynamic Pressure Transducer Employing a Micro-Filter - A pressure transducer assembly that uses static pressure compensation to capture low-level dynamic pressures in high temperature environments. In one embodiment, a method comprises receiving, at a first tube, a pressure, wherein the pressure includes a static pressure component and a dynamic pressure component; receiving, at a micro-filter, the pressure; filtering, by the micro-filter, at least a portion of the dynamic pressure component of the pressure; outputting, from the micro-filter, a filtered pressure; receiving, at a first surface of a first sensing element, the pressure; receiving, at a second surface of the first sensing element, the filtered pressure; measuring, by the first sensing element, a difference between the pressure and the filtered pressure, wherein the difference is associated with the dynamic pressure component of the pressure; and outputting, from the first sensing element, a first pressure signal associated with the dynamic pressure component of the pressure. | 03-06-2014 |
| 20140102205 | PIPELINE INSPECTION GAUGE (PIG) ALERT SYSTEM - The pipeline inspection gauge (PIG) alert system provides a method and apparatus for effectively locating a pipeline inspection gauge (PIG) as it traverses a pipeline. The method and apparatus incorporates hollow, empty tubes spaced along the length of the pipeline. The tubes are provided with lower ends that extend into the pipeline. The tubes are closed at their lower ends and connectable to respective pressure detection devices or the like at their upper ends. When a PIG passes through the pipeline, it contacts the lower end of the tube that extends into the pipeline, causing the tube to break, and thus opening the interior of the tube to the pressurized flow of the product flowing in the pipeline. The change in pressure is registered by the pressure detection device to indicate the passage of the PIG. | 04-17-2014 |
| 20140216162 | Sensor for High Pressure Processing of Articles - A pressure sensor device and its use for confirming achievement of a selected pressure in a high pressure process (HPP) for sanitizing food is disclosed. The device includes at least a base and a sheet, each of which is substantially impermeable to the working fluid of the HPP and is deformable at the selected pressure. Microcapsules interposed between flat overlapping portions of the base and sheet contain a color former and burst upon pressurization of the environment surrounding the device. Release of the color former is detected to confirm that the pressurization occurred. The device can be associated with one or more foodstuffs (e.g., a packaged food product or a group of such packages) and remain associated therewith to continuously indicate that the foodstuff(s) have been subjected to the selected pressure and are therefore sanitized. | 08-07-2014 |
