| 073450500 | With immersion | 6 |
| 20090078028 | INTELLIGENT UNDERWATER LEAK DETECTION SYSTEM - A subsea leak detection system is disclosed which includes a plurality of subsea leak detection sensors and a leak detection controller adapted to receive leak detection data from the plurality of subsea leak detection sensors and direct the sensing activities of the plurality of subsea leak detection sensors based upon the received leak detection data. | 03-26-2009 |
| 20100089129 | Apparatus and Method for a Seal Immersion Test with Aerated Fluid - A test apparatus for testing fluid seals within an aerated fluid includes a container and a fluid located within the container. A plurality of seal coupons are submerged within the fluid in the container. An air supply is connected to the container to aerate the fluid within the container. Testing the seal coupons includes flowing air from he air supply through the fluid to contact the seal coupons. After the air has contacted the seal coupons then the plurality of seal coupons are removed from the fluid. A value for at least one characteristic of the seal coupons is then compared with a standard value. | 04-15-2010 |
| 20100212404 | METHOD AND APPARATUS FOR LEAK DETECTION IN HORIZONTAL CYLINDRICAL STORAGE TANKS - A safe, precise, and cost effective storage tank leak detection system. Embodiments include two highly precise quartz crystal type pressure transducers held at a constant temperature. A bubbler to achieve access to the hydrostatic pressure at the tank bottom and just below the liquid surface. First transducer and bubbler are used to measure fluid mass while second transducer and bubbler are used to measure fluid density then used in combination with data correction and regression techniques to yield a storage tank leak detection system for use in horizontal cylindrically shaped tanks with an extremely low leak detection threshold. The storage tank leak detection system is thought to be most useful for detecting and measuring very small leaks in large horizontal cylindrical storage tanks. | 08-26-2010 |
| 20130312494 | LIQUID SUBMERGED PORTION FUEL LEAKAGE DIAGNOSTIC APPARATUS - A liquid submerged portion fuel leakage diagnostic apparatus includes a tank internal pressure detection portion; a liquid level detection portion; to reference-state liquid level extraction portion configured to extract, as a reference-state liquid level, a liquid level detected by the liquid level defection portion, when a tank internal pressure detected by the tank internal pressure detection portion becomes equal to a reference internal pressure; a fuel consumption detection portion configured to detect consumption of fuel in a fuel tank; and a fuel leakage diagnostic portion configured such that if the fuel consumption is not detected by the fuel consumption detection portion during a period between extraction timings at which the reference-state liquid levels are extracted by the reference-state liquid level extraction portion, the fuel leakage diagnostic portion diagnoses presence or absence of fuel leakage from a liquid submerged portion based on comparison of the reference-state liquid levels. | 11-28-2013 |
| 20140250982 | IMMERSION INSPECTION SYSTEM FOR A MACHINE AND RELATED METHOD OF OPERATION - Systems, devices, and methods, adapted to immersively test/inspect machine components (e.g., tubes, conduits, etc.) in an in-situ manner are disclosed. In one embodiment, a system includes: a first seal member configured to sealingly engage a first portion of a machine component; a base system connected to the first seal member and configured to extend within the machine component, the base system including: a housing; and a inspection device disposed within the housing and configured to inspect the machine component; and a second seal member connected to the base system and configured to sealingly engage a second portion of the machine component. | 09-11-2014 |
| 073450600 | Pneumatic tire | 1 |
| 20090241643 | TIRE PRESSURE MONITORING SYSTEM - Tire pressure monitoring system for a vehicle includes sensor units mounted in each tire of the vehicle, each sensor unit being operable to output an RF signal indicative of the pressure in the tire in which it is mounted; a pair of communicator units for receiving signals from said sensor units, said pair of communicator units being provided at different locations on the vehicle; and a control unit connected to said communicator units wherein said control unit is operable to determine which sensor unit is associated with which tire by monitoring the strength of the RF signal received from each respective sensor unit by each communicator unit. | 10-01-2009 |
