摘要： A cover for a manhole (10) including panels (4) movable within and parallel to a frame (1) attached to a flange (12) of the manhole (10). The panels (4) are readily movable so that the manhole may be selectively sealed or left slightly ajar, especially when the panels (4) include facing notches (5).

摘要： A digital oscillator including an oscillator (40), a counter (41), a memory (42), a digital-to-analog converter (43) and a low-pass filter (44) is disclosed. The memory is able to store a complex signal directly, such that a real-time computing unit is no longer required. The oscillator is particularly suitable for eddy current measurements.

摘要： An eddy current sensor (22a) including two transmitter windings (26) and a receiver winding (28) is provided for non-destructively testing an electrically conductive part (T). The three windings are arranged symmetrically relative to a reference plane (P1) extending perpendicularly to the surface of the part (T). The receiver winding (28) is positioned between the active portions (26a) of the transmitter windings (26) and perpendicular to the plane (P1), whereas the transmitter windings (26) are substantially parallel thereto. The coils and connections of the transmitter windings are such that no current flows through the receiver winding in the absence of a defect. Equipment for testing a tube (T) such as a steam generator tube includes two sensors at right angles to one another.
摘要翻译：提供包括两个发射器绕组（26）和接收器绕组（28）的涡流传感器（22a），用于对导电部分（T）进行非破坏性测试。三个绕组相对于垂直于零件（T）的表面延伸的参考平面（P1）对称布置。接收器绕组（28）位于发射器绕组（26）的有效部分（26a）之间并且垂直于平面（P1），而发射器绕组（26）基本上与其平行。发射器绕组的线圈和连接使得在没有缺陷的情况下没有电流流过接收器绕组。用于测试诸如蒸汽发生器管的管（T）的设备包括彼此成直角的两个传感器。
