  • Patent number: 4700574
    Abstract: An ultrasonic beam is made to penetrate into the rail from the median surface (A) of the rolling table of the rail along a direction forming in horizontal projection an angle (.alpha..sub.1) comprised between 10.degree. and 25.degree. with the longitudinal axis of the rail and in vertical projection an angle (.alpha..sub.2) with the symmetric plane of the rail comprised between 60.degree. and 80.degree.. The echoes reflected by a displaced oval flaw are detected either directly or indirectly.
    Type: Grant

  • Patent number: 4700564
    Abstract: The invention relates to the location of singular points in the automatic control of railway tracks. According to a possible embodiment, the railway carriage (11) carrying the control equipments is provided with radar antennas (25a, 25b) orientated to detect catenary posts (13) and more particularly their registration arms.

  • Patent number: 4689995
    Abstract: A device for inspecting a rail 2 of a railway track comprises a truck 1 running on the rail and carried by a railway vehicle. The truck carries at least one ultrasonic emitter and/or receiver probe 7, 8 in contact with the upper surface of the rail. At least one probe 8 is displaceable on a slide 6 while another probe 7 is fixed to the truck 1. The device comprises a jack 9 for displacing the probe 8 as a function of variations of the energy received by the receiver probe to compensate for fluctuations in the height of the rail.

  • Patent number: 4662224
    Abstract: Apparatus for the inspection of track rails. The device comprises a truck (4) capable of displacement on the track, and comprises at least two ultrasound emitter and/or receiver probes (V, O.sub.1, O.sub.2) emitting in different directions, applied against the rolling plane of the rail (1) and at least an ultrasound prove (SA) provided at the vicinity of the rail, laterally offset, emitting an ultrasound beam to the side of the rail web. Application particularly to the detection and recognition of rail fish-plates.

  • Patent number: 4467653
    Abstract: A transducer located in a reservoir that contains ultrasound-transmitting liquid directs and receives beams of ultrasound onto and from a rotating reflector which is also located in the reservoir. A diaphragm transmits the ultrasound from the liquid to a body which is to be analyzed. The results of the ultrasonic analysis are displayed on a cathode ray tube which is synchronized with the transducer and the rotating reflector.

  • Patent number: 4457178
    Abstract: Beams of ultrasound are transmitted into a rail. The transmission alternates between vertical and oblique beams. Transmission of the beams and reception of ultrasonic echoes is accomplished by a probe which includes a two channel ultrasonic transducer. The echoes are displayed simultaneously on two linear arrays of LED's which are arranged to resemble the relationship between a vertical beam and an oblique beam.
