摘要： A method for locating gas leaks from underground gas pipelines in which a first acoustic sensor having a first signal output is positioned in ground disposed substantially above or at a distance from the underground gas pipeline. At least one second acoustic sensor having a second signal output is positioned in the ground at a plurality of locations substantially above the underground gas pipeline. The output signals from the acoustic sensors are measured for each location of the second acoustic sensor and the signals are adaptively filtered to remove common noise signal components. The statistical minima of these rms voltages are determined for both the first output signal and the adaptively filtered second output signals and the differences determined. The location of the second acoustic sensor corresponding to the largest positive said difference is the location closest to the leak site.

摘要： A quick set of procedures for diagnosing the cause of a failure in a vacuum system having a pump and a chamber is disclosed. If the base pressure of the system has failed, but the rate of rise has not, then the most likely cause of the failure may be in the pump. If the rate of rise has failed, but the base pressure has not, then the most likely cause of the failure may be in the chamber. If the base pressure and rate of rise have both failed, then the most likely cause of the failure is in the chamber, but there is a slight chance of a failure in the pump. Measurements of the partial pressures of certain residual gases in the system may indicate a leak in the system. Measurements of the partial pressures of certain residual gases while turning off and on the lamps in the system may indicate a leak in the lamps. Measurements of the partial pressure of helium or other relevant gas, while moving a source of helium around the outside surface of the system, may determine the location of a leak.

摘要： A system and method for eliminating confusion associated with checking valves, wherein additional test points are added to the measurement of a valve for ensuring the verification of the actual sources of leaks or turbulence. A base line measurement for the valve is established by measuring the level of ultrasonic sound at the two points upstream from the valve. The level of the ultrasound at two downstream points is then measured. The value of the ultrasound at the downstream test points is compared to the values of the ultrasound at the upstream test points. If the values of ultrasound at the downstream test points are higher than the values of the ultrasound at the upstream test points, then the valve is leaking. If the values of the ultrasound at the downstream test points are close to or lower than the values of the ultrasound at the upstream test points, then the valve is not leaking, i.e., the valve is good.

摘要： An apparatus for permanently or semi-permanently fitting to an underground water pipe 15, 16 for detecting leaks therein, comprises a hydrophone 26 mounted to acoustically monitor water flowing along the pipe 15, 16 and means 29 for analysing a parameter of the output signal of the hydrophone 26 and for generating an alarm signal, in the event that the parameter is above a maximum value or below a minimum value. The apparatus further comprises a radio transmitter for transmitting the alarm signal to a remote receiver, so as to indicate the detection of a leak. The maximum and minimum values are preferably calculated using historical data obtained from the hydrophone 26, so that the values are automatically adjusted to suit location of the apparatus. In use, a plurality of leak detection apparatus can be installed to pipes at various locations around a geographical area of supply. Once a leak has been identified in an area, it is then a relatively simple matter to more precisely determine where in the area should be surveyed using a conventional leak detector. Thus, the need to survey the whole of the area using a conventional leak detector is avoided.

The ultrasonic leakage inspection device according to the present invention comprises an ultrasonic wave emitting unit having at least one ultrasonic emitting element for emitting an ultrasonic wave of a predetermined frequency and an ultrasonic detector including an ultrasonic sensor for detecting an ultrasonic wave. For leakage inspection of the items, the ultrasonic emitting unit is put inside the item in a sealed condition so that the ultrasonic wave is emitted uniformly inside the item, and the ultrasonic sensor is moved around the item. Any leakage defects of the item can be detected by sensing any ultrasonic wave leaked therefrom by the ultrasonic sensor.

摘要： In order to determine parameters of closed containers, primary mechanical oscillations are excited in a container wall. The secondary oscillations which are excited in the container by the primary mechanical oscillations of the container wall and which occur within the space between a closure and the liquid are picked up and analyzed, the parameters being determined from the ascertained frequency characteristic of these oscillations. In addition, the primary oscillations of the closure can also be picked up and analyzed, the internal pressure prevailing in the container being determined from the frequency of these primary oscillations. The frequencies of the primary and secondary oscillations can be determined by analysis of the frequency spectrum. The secondary oscillations can be picked up separately from the primary oscillations in that only those oscillations are picked up which occur within a time measurement window within which the primary oscillations have already decayed.

摘要： The present invention relates to a sealed vessel and a method of testing air tightness of the vessel. In the sealed vessel, the vessel body and a lid are sealed with two O-rings. The sealed vessel has a hole communicating the space sandwiched by the O-rings and the outside of the sealed vessel and a hole communicating the inside and outside of the sealed vessel. In case of testing the air tightness of the inner O-ring, gaseous helium is injected into the space sandwiched by the O-rings and the gaseous helium spread into the vessel is measured. In case of testing the air tightness of the outer O-ring, the vessel is pressurized by the gaseous helium from the outside and the gaseous helium spread in the space sandwiched by the O-rings is measured.
