Abstract: An apparatus and method for vaporizing liquid are provided which employ a plurality of rods disposed within a storage vessel that serve as the heat transfer element. While the plurality of rods are generally submerged by the liquid fuel to facilitate heat transfer and vaporization of the liquid fuel, the rods may be packed closely together such that the liquid inventory required to maintain the rods in a submerged state is substantially less than required by conventional fuel supply systems, thereby permitting the weight of a fuel supply system that incorporates the apparatus and method to be reduced while still permitting effective vaporization of the fuel.

Abstract: An apparatus and method for gas/liquid separation on an array of jets or streams of liquid is provided. Layers of structured packing material are configured to “quiet” high-velocity liquid flow with entrained gas to provide a flow at moderate or low velocity from which the gas has been substantially separated from the liquid.

Abstract: A hydrogen sensor having a palladium film layer used for the detection of hydrogen, e.g., in an environment susceptible to the incursion or generation of hydrogen. The palladium film layer is coated with a thin zeolite membrane that minimizes palladium surface poisoning that can occur due to the presence of atmospheric contaminants such as water vapor, ammonia, methane, carbon monoxide, and/or carbon disulphide. This improves the performance and reliability of the sensor to pinpoint hydrogen leak locations.

Abstract: A hidrogen detection system (14) includes a hydrogen sensor(16) that detects contamination within a reaction member and generates a hydrogen contamination signal. A surface spectroscopic system (18) is operational in conjuction with the hydrogen sensor (16) and determines contamination of the hydrogen sensor (16) and generates a sensor contamination signal. A controller (20) is electrically coupled to the hydrogen sensor (16) and the surface spectroscopic system (18) and compares the hydrogen contamination signal to the sensor contamination signal and generates a corrected hydrogen contamination signal.

Abstract: A magnetic sector for a non-scanning mass spectrometer includes a high permeability yoke with opposing faces to which are attached high energy product magnets and shaped pole pieces separated by a gap so that a high magnetic flux exists in the gap. The high magnetic flux in the gap enables very small surface areas of the pole pices faces forming the gap so that the overall magetic sector volume and weight are reduced.
