  • Patent number: 10458852
    Abstract: A system for detecting a temperature of a railroad train wheel or bearing includes a thermal line scanner and a processor. The thermal line scanner is positioned to capture a plurality of thermal line scans of the wheel or bearing. The processor is configured to analyze each of the plurality of thermal line scans, identify a selected line of the plurality of thermal line scans, and calculate the temperature of the wheel or the bearing based on the selected line. Thus, the system and method disclosed herein reduce the acquired thermal data first to a single line for one or both of the wheel temperature and bearing temperature and then to single values.

  • Patent number: 10392754
    Abstract: A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5? of lateral support along the side of the rail base while the traditional e clip fastener provides only 3? of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

  • Publication number: 20190144020
    Abstract: A device attached to a railcar of a train is provided. The device comprises a radio frequency (RF) transceiver to transmit and receive a RF signal. The device includes a RF modem configured to convert the received RF signal into a low frequency (LF) analog signal. The device includes a digital signal processor to process the LF signal. The digital signal processor includes a phase detector, a loop filter, and a digitally controlled oscillator. The phase detector compares the LF signal and a reference signal to generate an error signal. The phase detector also determines a state of the digital signal processor, the state being one of a lock state or an out of lock state. Further, the phase detector detects an event that the RF signal is lost and generate a loss signal. The loop filter filters the error signal and generates an error control signal. The digitally controlled oscillator generates the reference signal based on the error control signal, the state, and the loss signal.

  • Publication number: 20180291854
    Abstract: A nozzle assembly for a fuel injector includes a nozzle body and a needle tip positioned within the nozzle body. The needle check includes a terminal end surface positioned in spaced, facing relation to a sac surface of the nozzle body, to form a sac cavity. The terminal end surface and sac surface each have spherical shapes, and are centered about a longitudinal axis of the nozzle body. Structures of the terminal end surface and the sac surface are such that a clearance between them is nowhere less than along a line segment between centers of the terminal end surface and the sac surface, the sac cavity has a reduced volume, and wall thickness at the nozzle tip is sufficient for improved fracture resistance.
