摘要： A system and method of communicating via digital radio between a train and a device positioned at the wayside of a railway system, wherein the device detects defects at the wayside and information related to the defects is transmitted from the wayside to the train for display in the locomotive cab. A communications unit having a microprocessor control circuit and a transceiver is electrically coupled, preferably by serial connection, to the defect detector along the wayside. The transceiver of the communications unit is in radio communication with an existing transceiver in the head-of-train (HOT) unit located in the locomotive cab at the head-end of the train. The head-of-train unit has a microprocessor control circuit that drives a display which is preferably alphanumeric, for the purpose of displaying messages related to the defects detected by the defect detector at the wayside, and subsequently transmitted between the transceiver of the communications unit and the transceiver of the HOT unit. In a preferred embodiment, the HOT unit includes recording apparatus for recording the messages displayed and an alarm for notifying an operator that a message is being displayed.

摘要： A cleaning device for an endless conveyor of the type comprising an endless belt having an upper conveyor run and a lower return run which are guided over rollers at each end of the conveyor. The cleaning device is arranged to exert a cleaning action on the underside of the return run of the conveyor belt and to be driven directly or indirectly by the linear motion of the conveyor belt and/or from a drive train coupled with the conveyor belt. The cleaning device includes a rotatable brush having its axis of rotation extending below the return run and transversely of the direction of travel of the return run. The brush has cleaning elements extending outwardly of the brush axis and in which the outer ends of the elements are engageable with the underside of the return run upon rotation of the brush. A cradle is located at one end of the brush on which the brush is rotatably mounted. The spacing of the brush axis relative to the underside of the return run can be adjusted. Biasing devices are provided to urge the brush axis towards the underside of the return run to press the outer ends of the cleaning elements into cleaning contact therewith.
