摘要： A method and apparatus for inspecting the profile of the inner wall of a conduit, such as a heat exchanger in a steam generator by a probe body that includes eddy current sensing coils. The number of eddy current sensing coils is increased for more completely sensing the conduit surface without a corresponding increase in coaxial cables by the use of a bank switch which switches respective banks of coils to existing conduits.

摘要： A method of effecting an examination by eddy current means (24) of the surface of a coated component (58) for cracks having at least a preset minimal dimension. The subject method can be used to detect such cracks in the surface of metal components (58) that are coated or covered with a nonmetallic material. Further, through the use of the subject method such cracks are detectable without necessitating the removal of the nonmetallic coating or covering from the surface of the metal component (58). The subject method encompasses the steps of establishing calibration readings for cracks of the desired dimension utilizing the eddy current means (24) with which the desired surface examination of the given component (58) is to be effected, performing a preexamination validation of the operativeness of the eddy current means (24), and conducting with the eddy current means (24) the surface examination of the given metal component (58) that is coated or covered with a nonmetallic material.

摘要： A probe (10) for scanning the interior of a curved conduit (28) has a carrier (12) with a rotatable portion (12b). Sensor means (18) are secured to the rotatable portion (12b) and are aligned with respect to the curvature of the conduit by means of an elongated flat strip (20), secured to the rotatable portion (12b) and extending longitudinally therefrom. Driving means (14) is provided to urge the probe (10) longitudinally through the conduit (28).

摘要： A support framework has casters which enable it to be moved into position for receiving the studs of nuclear reactor vessels so the studs may be cleaned and inspected. A housing on the framework isolates the stud while it is cleaned to control the radioactive debris removed from the stud surfaces. Brushes for the internal bore and external surface of the stud are mounted for simultaneously moving over the stud surfaces. Eddy current and ultrasonic inspection devices are substituted for the brushes and the internal and external surfaces simultaneously inspected while an encoder connected to both the inspection devices and stud manifest the location of any detected flaws.
摘要翻译：支撑框架具有脚轮，能够将其移动到接收核反应堆船柱的位置，从而可以对螺柱进行清洁和检查。框架上的外壳在清洁螺栓时将螺柱隔离，以控制从螺柱表面移除的放射性碎屑。螺柱的内孔和外表面的刷子被安装以同时移动在螺柱表面上。涡流和超声波检测装置代替同时检查的电刷和内外表面，同时连接到检查装置和螺柱的编码器显示出任何检测到的缺陷的位置。

摘要： A "caseless" rocket having a solid propellant grain body which as a result of its shape and surface burning creates, in effect, an outer case or barrier formed by the surrounding airstream and the burning propellant. An exhaust "nozzle" is generated as an annulus in which the air stream serves as one surface while the propellant grain serves as the other. Stores or a payload are enclosed within the propellant body.
