Publication number: 20100155543Abstract: A system (10) for sensing a condition of a rail vehicle undercarriage component (e.g., 18) includes a sensor (e.g., 12) comprising an array of infrared sensing elements (29). Each of the elements may be aimed at a different region of a target area (e.g., 32) of a rail vehicle undercarriage component to generate respective scanning waveform signature data corresponding to each different region. The sensor may be oriented so that at least one of the elements receives unobstructed infrared emissions (e.g., 33) from the undercarriage component of a rail vehicle passing the sensor. The system also includes a memory (42) for storing characteristic waveform signature data corresponding to known undercarriage components.Type: ApplicationFiled: March 3, 2010Publication date: June 24, 2010Inventors: Peter Hesser, Thomas Strecker, Miles Metschke, Thomas Shanahan, Daniel Kurt Stevens, Mathias Hartmann

Patent number: 4757945Abstract: A device to be placed on a railway sleeper (1) or some other foundation for a railway rail (3) includes a pad (2) and two upstanding portions (6A). The pad (2) is of resilient and electrically insulating material and the upstanding portions (6A) are of stiffer electrically insulating material. At least two-thirds of the area of the pad (2) has none of the stiffer material above or below it. Preferably the upstanding portions (6A) are at least 150 mm. long and are on elongate members (6) which have ears (6B) at opposite ends which extend under only corners of the pad (2), where they are secured by spigots (2E) projecting into holes (6C).Type: GrantFiled: January 27, 1987Date of Patent: July 19, 1988Assignee: Pandrol LimitedInventor: Geoffrey G. Leeves

Patent number: 4569478Abstract: A system for fastening a rail to a foundation such as railroad ties or sleepers to form a railroad track. The system includes L-shaped inserts which are imbedded into the foundation and extending above it, supports which are laterally located with respect to the rails, and a fastening member or clip securing the rails. The main portion of each clip is mounted between the insert and the foundation, and one end contacts the upper surface of the supports. The other end of the clip contacts the flange of the rail, and has an offset lower surface which applies vertical and lateral pressure to the edge of the flange. The clip is made of a metal material and is a resilient spring having a multiple curved cross-section in order to apply compressive forces to the rail flange, the curved portions having undulating portions which make the various contacts.Type: GrantFiled: August 20, 1984Date of Patent: February 11, 1986Assignee: Dayco CorporationInventor: James S. Bryan

Patent number: 4111361Abstract: The device comprises a metal fastener which bears against the flange of the rail and against the rail support. An insulating element is combined with the fastener for insulating the fastener from the support and insulating the fastener from a fixing bolt which extends through an aperture in the fastener and is anchored in the rail support. The insulating element is in one piece and comprises a planar branch having an aperture for the passage of the fixing means and a loop portion which is so shaped as to ensure the elastic mounting of the insulating element on the fastener and to be interposed between the fastener and the support.Type: GrantFiled: March 24, 1977Date of Patent: September 5, 1978Assignee: Suprotec S.A.Inventor: Roger Paul Sonneville

Patent number: 4061270Abstract: A unitized insulating element for use with a steel cross tie is provided. The insulating element is operative to electrically insulate the rail from the steel tie, from retaining elements associated with the tie which prevent lateral movement of the rail relative to the tie and from rail anchors which prevent longitudinal movement of the rail relative to the tie. The insulating element permits use of the rail as an on-line signal control conveying device when steel ties are used and is configured as a tie plate substitute from providing an inwardly-directed cant for the rail to be retained thereon.Type: GrantFiled: April 9, 1976Date of Patent: December 6, 1977Assignee: United States Steel CorporationInventor: Joseph M. Wandrisco
