摘要： PURPOSE: To heighten sensitivity for detecting the crack of a steam pipe of a nuclear reactor. CONSTITUTION: Beams emitted from a convertor 1 proceed along transmission routes 7, 8, 9 toward the wall 4 of a pipe with certain angles. The angles are larger than an incident critical angle in respective cases, and as the result parts of the beams further enter the wall 4 insides of the pipe. The two transmission routes 8, 9 are such routes as two beams join in a zone of the wall 4 of the pipe. A sound wave reflected from the route 8 at a place of the inner wall face 5 of the pipe returns to the converter through the route 9, and the reverse is conducted regarding the route 9.

摘要： A method is described for producing a building element in which a hardenable binder-material is mixed with a coarse particles comprising material after which the mixture is used for forming unhardened building elements. The building elements are subsequently hardened at a temperature up to 100°C and at atmospheric pressure in a water-vapour containing atmosphere. The hardenable binder material is constituted by a separately prepared mixture of fly ash; Ca(OH) ? or a substance which may be converted into Ca(OH) 2 , and water.Optionally the hardenable mixture may be partially granulated before use.

摘要： Ultrasound pulses from an emitter-receiver (1) are sent along a transmission path (7) parallel to the pipe under examination and are reflected by a multiple reflection device with 2 planes of reflection (2,3) which define 2 other transmission paths (8,9). The ultrasound beam is therefore projected onto the wall (4) of the pipe, making an angle of incidence less than 90 deg. but greater than the critical angle so that the beam partially penetrates the wall. The beam reflected at the internal (5) or external (6) face of the wall (4) arriving by one path (8) returns to the emitter-receiver (1) by the second path (9) and vice versa, except for any reflections caused by cracks in the wall, allowing the presence of cracks to be detected.

摘要： An apparatus is provided for carrying mobile means of inspection in the interior of a tubular body, the means of inspection being adapted to emit and receive at least one sweeping radiation beam for inspection purposes. The apparatus includes a pair of carrier assemblies (1,2), coupled together by a bridge which has at least two linking pieces (3,4) and a coupling piece (5) therebetween. The apparatus also has a reflector (7) with at least as many reflection planes (10,11) as the bridge has linking pieces (3,4), each of which reflection planes defines a transmission path. The reflector (7) is rotatable about a longitudinal axis (20) through the carrier assemblies (1,2), the reflection planes (10,11) being so arranged that at least one transmission path extends to the interior of the tubular body at any one time. Part of each transmission path is longitudinal and part is perpendicular to the longitudinal axis. The reflection planes are arranged so as to partially overlap.
