摘要： A nozzle for delivering fuel from a fueling station that can be remotely triggered to shut-off prior to the receiving fuel tank being filled. The nozzle includes a valve that can be opened by a lever and latched into the open position for continuous filling. The nozzle handle has an actuator positioned to cause the latch to release the lever and a controller that can energize the actuator in response to receipt of a wireless signal indicating that the delivery of fuel should be terminated. A wireless communication interface of the nozzle is in wireless communication with a fuel management system that can monitor a fuel flow meter to signal the nozzle to shut-off when the amount of fuel that has been delivered reaches a predetermined amount.

摘要： A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

摘要： A computer controlled locomotive brake (CCB) configured for setting and releasing the retainer valves of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the retainer valve release pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all retainer valves are released and the train has sufficient braking system recharge to safely control movement of the train.

摘要： A system for waking up a dormant car control device of rail car braking system that provides a sufficient wake up voltage in response to pressurization of the brake pipe of the transit car. A supercapacitor is used to output a predetermined voltage when a pressure switch responsive to a source of brake pipe pressure moves to a closed position in response to a charging of the brake system. A first circuit boosts the predetermined voltage of the supercapacitor and energized the contacts of a relay that can selectively provide the boosted voltage to an input of a car control device. A second circuit controls the relay to select when boosted voltage should be provided to the input of a car control device. A third circuit selectively provides power to the first and second circuits based on whether the car control device should receive the boosted voltage.

摘要： A system that allows an electronically controlled pneumatic (ECP) railcar to be optionally selected as the ECP End of Train (EOT) device when that car is positioned at the end of a train regardless of its physical orientation. This eliminates the requirement to use and install a traditional End of Train (EOT) device at the end of an ECP train while maintaining the same train integrity monitoring functionality that is typically provided for train brake-in-two detection and closed cut-out cock detection. The system also eliminates the requirement for a dedicated EOT device at the end of the train for ECP “RUN” Mode operation, and allows any ECP car to function normally as part of the train or act as the EOT device when selected.

摘要： A brake cylinder maintaining system that combines a brake cylinder maintaining check valve and a quick service limiting valve into a single unit to have lower hysteresis, and thus more precise BCM regulation pressure and a smaller pressure offset. The check valve and quick service valve are coupled to provide a single system having multiple valve seats for selective communication between quick service pressure and brake cylinder pressure on one hand, and between a brake cylinder maintaining pressure and brake cylinder pressure on the other hand.

摘要： A gladhand coupling that prevents inadvertent separation of the coupling halves without the need for additional structure or manipulation to connect and disconnect the halves. Each half is equipped with a lug having a ramped pad and a flange defining a channel having a corresponding ramped pad. When two halves are positioned together then rotated into the locked position, the ramped pad of the lug is positioned proximately to the ramped pad of the flange to prevent inadvertent lateral compression of the two halves that could cause unintentional uncoupling. The coupling may be disconnected by simple rotation of one coupling half relative to the other and by pulling the coupling apart as done by current rail car decoupling procedures without the need for manual manipulation of extraneous locking mechanisms.

摘要： A replacement cartridge for repairing rather than replacing an angle cock. The cartridge has a ball key with a ball and a shaft. A unitary ball seat that has first and second internal bearing surfaces for engaging the ball is used to support the ball key when installed in the angle cock body that is being repaired. A cover is positioned over the ball seat and defines a bore through which the shaft of the ball key extends. A handle is coupled to the shaft of the ball key so that a user may rotate the ball between the internal bearing surfaces between an open position and a closed position.

摘要： A train control system that can be integrated into a locomotive having a distributed power mode. The train control system includes a router interposed in a communication link between the locomotive computer and the distributed power module that is responsible for telling the locomotive computer whether distributed power mode is active or inactive. The train control system controls the router to obtain any locomotive operational data sent from the locomotive computer to the distributed power module for use by the train control system. The router may additionally intercept and block communications from the distributed power module to the locomotive computer and replace the communications with messages that cause the locomotive computer to provide locomotive operational data that is would not otherwise output in a particular distributed power state.

摘要： An intelligent, on-board, train brake safety monitoring and fault action system is disclosed. The system compares measured dynamic train brake performance using on-board train control system, such as a LEADER® system. Using the measured dynamic train brake performance, the brake monitoring system can determine whether the train is capable of stopping within a particular required distance, such as a stop distance set by a positive train control system in which the train is participating. The ongoing ability to meet external braking criteria, such as compliance with positive train control stop distances, may be used to extend the interval between any mandated train brake inspections and tests.
