    摘要: The present invention concerns the inspection of rail tracks. A rail inspection device comprises a compliant, approximately circular spacer, and a spring-loaded electromagnetic sensor positioned within the approximately circular spacer. The spacer has an inner surface and an outer surface, with the distance between the inner surface and outer surface defining the thickness of the spacer. The thickness of the spacer varies around the circumference of the spacer, and the electromagnetic sensor is urged against the inner surface of the spacer such that, in use, the outer surface of the spacer is in contact with the rail under inspection.

    摘要: A method includes positioning a coil antenna in a first pipe concentrically arranged within a second pipe, the coil antenna having a first terminal, a second terminal, and one or more wires that exhibit a winding density proceeding radially between the first and second terminals according to a given function. The first and second terminals are then excited with an alternating current or voltage, and a signal is measured between the first and second terminals. A characteristic of at least one of the first and second pipes is then calculated based on the signal.

    摘要: A method for inspecting an object. A support structure physically associated with a first sensor and a second sensor is moved to an area for inspection. The support structure is in a first configuration and the first sensor and the second sensor are positioned about an axis extending through the support structure when the support structure is in the first configuration. The support structure is changed from the first configuration to a second configuration. The first sensor and the second sensor are configured to generate information when the support structure is in the second configuration.

    摘要: A group of inventions related to geophysical well logging, in particular to magnetic imaging defectoscopy of well casings including magnetised ones, that can be used to identify and classify defects in production and intermediate casing and tubing strings in oil and gas wells. An electromagnetic multi-sensor defectoscope for surveying casing pipes containing a source of the electromagnetic field in the form of a central exciter coil designed to transmit current pulses from a current pulse generator, a system of measuring elements placed on bow springs to be forced against the inner surface of a casing pipe, and a unit for signal recording, control and data processing connected to the system of measuring elements through communication lines, with the system of measuring elements designed to record signals proportional to the longitudinal component of the electromagnetic field consisting of at least three compensated sensors, each placed on the inner side of a bow spring and being equidistant from one another along the circumference of the cross-section of a casing pipe to ensure reliable detection of defects within its surveyed section. A method of multi-sensor electromagnetic defectoscopy for surveying casing pipes, in which an electromagnetic field is generated within the surveyed section of a casing pipe by current pulses, and mainly response signals of the secondary electromagnetic field are measured in the intervals between excitation pulses using a system of measuring elements, while most response signals of the primary electromagnetic field are compensated, and the signals are then transmitted into a signal recording, control and data processing unit recording the time dependence of the output EMF of the signal of the system of measuring elements. Two independent claims, eight dependent claims and two figures.
