  • Patent number: 6846371
    Abstract: A method of producing a high-strength high-toughness martensitic stainless steel seamless pipe which includes heating a martensitic stainless steel raw material to an austenitic range and subjecting the raw material to piercing and elongating to form an original pipe. The original pipe is cooled to form a structure substantially composed of martensite in the original pipe. The original pipe is reheated to a temperature in the dual-phase range between the Ac1 transformation point and the Ac3 transformation point, and is subjected to finishing rolling at an initial rolling temperature T (° C.) between the Ac1 transformation point and the Ac3 transformation point. The original pipe is then cooled to form a processed pipe. The processed pipe is tempered at a temperature below the Ac1 transformation point. The reduction in area R in the finishing rolling step may be in the range of 10% to 90%, and the initial rolling temperature T and the reduction in area R may satisfy the relationship 800?T?0.625R?850.

  • Patent number: 6845953
    Abstract: A train control system includes a control module that determines a position of a train using a positioning system and consults a database to determine when the train is approaching a portion of track monitored by a track circuit. When the train is near a track circuit, but while the train is still far enough away from the track circuit such that the train can be stopped before reaching the portion of track monitored by the track circuit, the train transmits an interrogation message to a transceiver associated with the track circuit. When the track circuit receives the interrogation message, a test is initiated. The test results are transmitted back to the train. The train takes corrective action if the track circuit fails to respond or indicates a problem.
