Abstract: Provided is an apparatus for connecting two sub-flow systems (e.g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.

Abstract: An adjustable fuel nozzle assembly [1000] for spraying fuel into a recovery boiler [13] includes at least two fuel nozzle assemblies [1100, 1300]. An adjustment section [1500] adapted to adjust the relative orientation between the nozzle assemblies [1100, 1300] and hold them at the desired orientation relative to each other to create a desired spray pattern. The adjustment section [1500] also adapted to simultaneously aim several fuel nozzles at a target location, retaining their relative orientation between the nozzle assemblies [1100, 1300]. This allows the nozzle assemblies [1100, 1300] to spray fuel with a desired spray pattern to a desired location to properly control combustion of the recovery boiler [13], thereby increasing stability of combustion minimizing the creation of pollutants such as NOx gases.

Abstract: A battery assembly may include a cooling system assembly having first and second battery modules and a coolant manifold in fluid communication therewith. The first battery module may include a first coolant flow path and the second battery module may include a second coolant flow path. The coolant manifold may include first and second ports and a main body portion to provide expansion and contraction between the first and second ports. The first port may be in communication with the first flow path and the second port may be in communication with the second flow path.
