Abstract: The system may comprise a Proton Exchange Membrane Fuel Cell (PEM FC) stack that is connected to and provides energy to a microgrid for back-up applications, is connected to and provides energy to a fast-charge battery electric vehicle station (BEV) for fast charging of Electric Vehicles (EVs) and is connected to and provides hydrogen to a hydrogen dispenser for fueling Fuel Cell Vehicles (FCVs). Utilizing an integrated forecourt to support several different energy delivery applications and technologies may result in improved overall project economics and may accelerate the transition to a low/zero carbon economy for transportation and stationary back-up power.

Abstract: Aircraft, enhanced flight vision systems, and methods for displaying an approaching runway area are provided. In one example, an aircraft includes a display disposed in a cockpit area. A radar imaging and post-processing arrangement is in communication with the display via a processor. The radar imaging and post-processing arrangement is operative to generate a radar image of an approaching runway area, generate a symbology corresponding to the approaching runway area and/or compare the radar image to a synthetic vision (SV) database to align an SV runway area with the radar image to define an aligned SV runway area, and to communicate the symbology and/or the aligned SV runway area to the display.

Abstract: A system and a method for drone detection and collision avoidance, particularly for use in an aircraft, is provided. The system includes, but is not limited to a sensor, a processor, and an avoidance unit comprising a control unit. The sensor is configured to detect a drone signal in a predetermined space and to transmit the drone signal to the processor. The processor is configured to determine the presence of a drone in the predetermined space based on the drone signal. The processor is configured to transmit a command to the avoidance unit when the processor determines the presence of a drone. The control unit is configured to receive the command and to generate a warning signal in response to receiving the command.

Abstract: A communication node, such as a line replaceable unit and/or a sensor for use in a distributed communication network in a vehicle, particularly an aircraft, is provided. The communication node includes, but is not limited to a communication module and a processor unit. The communication module is configured to communicate with a target communication module of a target communication node of a plurality of communication nodes in the distributed communication network in the vehicle. The processor unit is configured to automatically and dynamically determine an optimum communication path through the communication network for communication between the particular communication node and a target communication node and to configure the communication module to exchange data with the target communication node over the optimum communication path through the distributed communication network.

Abstract: An actuating system for manually operating the doors of a railroad hopper car. An operating shaft having a handle is rigidly coupled to an actuating lever. A door opening lever, which is rotatably coupled to said actuating lever, is rotatably coupled to the door for a hopper chute. To operate the system, an operator rotates the handle of said operating shaft, rotating said actuating lever and said door opening lever, shifting said door from the closed to the open position.

Abstract: An apparatus for automatically opening and closing the covers of a covered hopper railroad car. After the covers are unlatched, the car is driven through the apparatus. The covers of the car are contacted by the bars of the apparatus, which lifts the covers to the open position. The car can then be filled. Continued advancement of the car causes the apparatus to close the hopper doors.

Abstract: An actuating system for operating sliding gates of a railway hopper car in which the mechanism contains an overcenter latch for insuring that the door remains closed when in the closed position for safety purposes.

Abstract: Base treated aluminas exhibit improved CO2 capacity over untreated aluminas. Base treated aluminas prepared by physically mixing alumina and base during forming have (1) a higher surface area, (2) less hydrothermal aging, (3) improved CO2 capacity and (4) lower cost than base treated aluminas produced by aqueous impregnation. A method for removing at least CO2 and water from a gas stream includes providing an adsorbent formed from a process comprising physically mixing activated alumina solids and solid salts of alkali metals, alkaline earth metals or ammonium ion; and contacting the gas stream with the adsorbent.

Abstract: A process and an apparatus for removal of radon from indoor air. The process having the step of contacting indoor air with an adsorbent, that is a silver-exchanged zeolite. The apparatus for the removal of radon from indoor air comprises a silver exchanged zeolite.

Abstract: An actuating system for operating the doors of a railroad hopper car while dumping the contents outside of the rails. A main lever is rotatably coupled within the center sill with a rod extending from an arm of the lever to a door which covers the hopper. As the lever is rotated, the rods act to move the doors away from the hoppers.

Abstract: An actuating system for operating transverse doors of a railroad hopper car. The mechanism includes an operating member which is coupled to a door or doors of the car by a shaft and a linkage which couples a power source to the operating member, where the operating member rotates to move the door away from the hopper. The mechanism can operate doors which open in opposed direction with a single power source. The mechanism can be used in new car construction, and can be retrofitted onto existing hopper cars.

Abstract: An actuating system for operating the doors of a railroad hopper car. The mechanism includes an air cylinder which is coupled to a first lever that is fixed on a shaft. The shaft is coupled to a second shaft through a pair of levers. Supplying air to the cylinder causes the first lever to rotate the shaft which causes the second shaft to rotate. The doors of the hopper are coupled to the two shafts, such that when the shafts rotate, the doors open from the hopper.

Abstract: A wayside electrical pick-up shoe for operating the discharge of a railcar. The shoe includes a counterweight for biasing the shoe against the rail. The pick-up shoe uses no springs in the design.

Abstract: A door position indicating mechanism for use with a railroad car. The mechanism includes a shaft which extends across the longitudinal direction of the car. An offset section of the shaft has a roller which contacts a lever which is shifted by an air cylinder when operating the door mechanism. At least one counterweight biases the roller into constant contact with the door operating lever. Indicators are mounted on either end of the shaft such that the position of the doors can be noted from either side of the railroad car.

Abstract: A system for operating the hopper doors of a railroad car as the car is in motion. The system includes an actuating device which is mounted on the surface adjacent the railroad tracks, and a mechanism mounted on the railcar which is contacted by the actuating device as the railcar rolls past the device. A first lever of the mechanism contacts an arm of the actuating device to open the hopper doors, while a second lever contacts the arm to close the hopper doors. The operation is accomplished without the use of powered cylinders or valves. The system can be used with railcars having either transverse hopper doors or longitudinal hopper doors.

Abstract: A mechanism for selectively operating hopper doors of a railroad car. A fulcrum coupled to the operating cylinder includes channels within which levers can be selectively activated to open specific doors of the car, thus allowing the contents of the railcar to be sequentially emptied. The mechanism can be installed on railcars having either transverse hopper doors or longitudinal hopper doors.

Abstract: An actuating system for operating longitudinal doors of a railroad hopper car. The mechanism includes an operating member which is coupled to each end of the door set of the car by a shaft and a linkage which couples a power source to the operating member, where the operating members rotate to move the doors away from the hopper. Reversing the rotation of the operating members closes the door set of the hopper. The mechanism can be used in new car construction, and can also be retrofitted onto existing hopper cars.
