摘要： A coupling mechanism for a sealing structure having interacting seals in non-parallel planes includes a male portion of a mechanical joint and a female portion of the mechanical joint. The male portion is coupled with a first sealing member contained in a first plane. The female portion is coupled with a second sealing member which is contained in a second plane. The second plane is different from the first plane. The male portion and the female portion of the mechanical joint are configured to mate for coupling the first sealing member with the second sealing member.

摘要： A system for adjusting wheel adhesion levels on multiple locomotive axles in a rail vehicle consist is provided. The system includes a first controller associated with a lead locomotive and a second controller associated with at least one trailing locomotive. A wheel adhesion level sensor is configured to detect a low wheel adhesion level at an axle and transmit that information to the first or second controller. The first controller adjusts the load being delivered to the axles by the motor in response to the low wheel adhesion level.

摘要： A valve assembly of a fuel supply system includes a first body defining a first bore, an inlet port to receive fuel into the first bore, and an outlet port. The valve assembly further includes a pneumatic chamber disposed in fluid communication with the first bore. The valve assembly further includes a first piston to move between a first position and a second position. The first piston restricts and allows flow of fuel from the inlet port to the outlet port, in the first position and the second position, respectively. The valve assembly further includes a vent passage located upstream of the pneumatic chamber and configured to receive fuel leaked from a flow path defined between the inlet port and the outlet port. The valve assembly also includes a check valve disposed in the vent passage and configured to selectively vent the fuel entering the vent passage.

摘要： A fatigue monitoring system is disclosed for use with a machine. The fatigue monitoring system may have an input device configured to generate a first signal indicative of an activity performed by a machine operator, a scanning device configured to generate a second signal indicative of a recognized characteristic of the machine operator, and a warning device. The fatigue monitoring system may also have a controller in communication with the input device, the scanning device, and the warning device. The controller may be configured to determine a time between generations of the first signal, to make a comparison of the recognized characteristic with a threshold characteristic, and to selectively activate the warning device based on the time or the comparison.

摘要： A method of operating a cryogenic fuel system for supplying fuel to an engine is provided herein. A cryogenic fuel pump is operated to pump fuel to be supplied to the engine. At least a portion of the pumped fuel is diverted to be supplied to an accumulator, when a fuel demand of the engine is less than a discharge output of the cryogenic fuel pump. Further, the supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped, when a pressure within the accumulator reaches a first predefined pressure limit. Furthermore, the fuel is supplied to the engine from the accumulator, when supply of the pumped fuel from the cryogenic fuel pump to the engine and the accumulator is stopped.

摘要： A rail conditioning system associated with a locomotive is provided. The locomotive operates on a rail. The rail conditioning system includes a fluid supply tank. The rail conditioning system also includes a first nozzle coupled to the locomotive. The first nozzle is adapted to direct a first beam of fluid received from the fluid supply tank towards a first portion of the rail. The rail conditioning system further includes a second nozzle coupled to the locomotive. The second nozzle is adapted to direct a second beam of fluid received from the fluid supply tank towards a second portion of the rail. The rail conditioning system includes a valve element provided in fluid communication with the first and second nozzles. The rail conditioning system further includes a control module in communication with the valve element.

摘要： An assembly for preventing abuse of a pump mounted to a driver equipment is provided. The driver equipment and the pump have a mutually intermeshed driver gear and a driven gear respectively. The assembly includes a coupler splined to a shaft of the pump and configured to transmit torque from the driven gear to the shaft. The assembly also includes fasteners that are configured to releasably fasten the coupler to an end face of the driven gear. The fasteners are configured to shear, and disconnect the coupler from the driven gear when a torque on the driven gear exceeds an operational torque of the pump.

摘要： An access point for a communication network is disclosed. The access point may have a communications processor configured to receive signals from a different access point of the communication network, a cable connected to the communications processor, and at least one attenuator connected to the cable upstream of the communications processor. The at least one attenuator may be configured to selectively attenuate incoming signals received via the cable before the incoming signals are received by the communications process. The access point may also have a transmission amplifier connected to the cable downstream of the communications processor and configured to amplify outgoing signals generated by the communications processor by about 3:1.
