摘要： The present invention allows for the fabrication of an EMAT system that eliminates static charge impulse noise. The EMAT system includes an EMAT, wear layer, and magnet. If the wear layer is made slightly conductive, the static charges slowly bleed off rather than build up to cause impulse discharges. This semiconductive wear layer does not attenuate the EMAT signals by introducing any additional distance between the EMAT coil and the conductive piping or by introducing any conductive material between the EMAT coil and the conductive piping. In the preferred embodiment, a wear layer of UHMW (ultra high molecular weight) polyethylene with a surface resistivity of about 10,000 ohms per square is utilized. The conductive UHMW polyethylene still acts as a wear layer, but now also acts as a semi-conductive static-dissipative interface between the EMAT coil and the piping.
摘要翻译：本发明允许制造消除静电荷脉冲噪声的EMAT系统。 EMAT系统包括EMAT，耐磨层和磁铁。如果磨损层略微导电，静电荷会缓慢渗出而不是积聚起来引起脉冲放电。该半导体耐磨层不会通过在EMAT线圈和导电管道之间引入任何附加距离或者在EMAT线圈和导电管道之间引入任何导电材料来衰减EMAT信号。在优选的实施方案中，使用表面电阻率为约10,000欧姆/平方的UHMW（超高分子量）聚乙烯的耐磨层。导电UHMW聚乙烯仍然作为耐磨层，但现在也作为EMAT线圈和管道之间的半导体静电消散界面。

摘要： An apparatus for non-intrusively indicating the passage of a pipeline pig having a housing adapted to be supported adjacent the exterior surface of a pipeline through which a magnet carrying pig moves, the housing containing an armature formed of pole pieces of paramagnetic material having a narrow gap therein that receives a solid-state magnetic sensing member, the sensing member providing changing electrical characteristics in response to changes in ambient magnetic field intensities, and an indicator pivotally attached to the housing and normally held in a ready position by a latch, the latch being operated by a circuit controlled by the magnetic sensing member so that the flag is released to move to an operative position in response to a changed magnetic field intensity caused by the passage of a magnet carrying pig, the armature within the housing serving to increase the sensitivity of the magnetic sensing member.

摘要： Two geophones located above an underground pipeline are spaced from each other and adjacent to both sides of a benchmark location. As a pig travels through the pipeline sound waves are generated. As a pig approaches a benchmark location, sound waves are received first by the geophone which is closest to the source of the sound waves, that is, the upstream geophone and then by the downstream geophone. The geophones generate electrical signals that are fed to a comparator circuit which is connected to upstream and downstream indicators, one of which is activated when a pig passes the benchmark depending on whether the sound was first received by the upstream or downstream geophone. An alternate embodiment adds a magnetometer at the benchmark location capable of sensing changes in the ambient magnetic field caused by the passage of a pig.

摘要： An apparatus for monitoring the motion of a railroad train includes an on-board unit which computes the speed, acceleration/deceleration, and distance traveled events of the train and stores such computed data for retention by a non-volatile memory after a power interruption or outage occurs. The apparatus also includes a portable unit to which the on-board unit, or the data retaining memory thereof, can be connected for conducting data transfers from the on-board unit memory to the portable unit. Once stored in the portable unit, the information can be formated and displayed as a history of the train operation for management and maintenance personnel, for example.
