Abstract:
A low-cost getter material comprising palladium and manganese oxide and methods of making the same. A tank including said getter material, and a method of removing hydrogen gas.
Abstract:
A cryogenic fluid delivery system includes a tank (22) adapted to contain a supply of cryogenic liquid (26), with the tank (22) including a head space (36) adapted to contain a vapor above the cryogenic liquid (26) stored in the tank (22). A liquid withdrawal line (28) is adapted to communicate with cryogenic liquid (26) stored in the tank (22). A vaporizer (32) has an inlet that is in communication with the liquid withdrawal line (28) and an outlet that is in communication with a vapor line. A pressure building circuit (55) is in communication with the vapor delivery line and the head space (36) of the tank. The pressure building circuit (55) includes a flow inducing device (52) and a control system for activating the flow inducing device (52) when a pressure within the head space (36) of the tank drops below a predetermined minimum pressure and/or when other conditions exist.
Abstract:
A nozzle includes a nozzle bayonet with a warm seal positioned at a distal end and a nose seal positioned at a proximal end so that a distal passage is defined between tire warm and nose seals. The nozzle also includes a nozzle poppet valve. Purge and vent lines are in fluid communication with the distal passage. A receptacle includes a receptacle poppet valve, a receptacle inner tube and a receptacle outer tube with a receptacle insulation space defined therebetween. A coupling space is defined between an outer casing and the receptacle outer lube. The receptacle coupling space receives the nozzle bayonet. The receptacle sequentially engages the warm seal and the nose seal of the nozzle during insertion of the nozzle bayonet into the receptacle coupling space with the nozzle and receptacle poppets engaging to open the nozzle and receptacle poppet valves when the nozzle bayonet is fully inserted into the receptacle coupling space.
Abstract:
A body structure includes an inlet port (15) that receives fluid from a delivery device, a first outlet port (12) that connects to a top-fill line in communication with a cryogenic tank, a second outlet port (13) that connects to a bottom-fill line in communication with a cryogenic tank and a slider tube cylinder (19). A cylinder housing (22) is connected to the body structure and has a pressure comparison cylinder with an upper volume (23) and a lower volume (27), with the latter in fluid communication with a cryogenic tank. A piston (21) slides within the pressure comparison cylinder and a piston shaft is connected to the piston. A pressure regulator (24) is in fluid communication with the upper volume of the pressure comparison cylinder and the slider tube cylinder. A slider tube (29) is connected to the piston shaft and slides within the slider tube cylinder. The slider tube cylinder directs fluid to a top-fill line through the first outlet port when a pressure in the lower volume exceeds a pressure setpoint and fluid to a bottom-fill line through the second outlet port when the pressure in the lower volume is below a pressure setpoint.
Abstract:
A cryogenic fluid delivery system includes a main tank system with a main tank adapted to contain a first supply of cryogenic liquid, and reserve tank system with reserve tank adapted to contain a second supply of cryogenic liquid. A pressure building circuit is adapted to delivery vapor to the head space of the main tank to build pressure in the main tank and a fuel delivery line supplies cryogenic fuel from either the main tank or the reserve tank to a use device. The reserve tank stores saturated cryogenic fuel that is delivered to the use device via the fuel delivery line while the cryogenic liquid in the main tank is being saturated. The fluid delivery system automatically switches to delivering cryogenic fuel from the main tank to the use device via the fuel delivery line upon saturation of the cryogenic liquid in the main tank.
