A computer-implemented system and method for obtaining product related information. Information related to a product obtained from a plurality of different sources is transformed into processed product data with a plurality of levels. Callouts and contexts are identified in the processed product data. A product-to-chemical continuum is generated by creating callout-context pathway segments between the plurality of levels of the processed product data based on the callouts and contexts identified. A query request for product information is transformed into a set of context search parameters, which is used to traverse the product-to-chemical continuum through the callout-context pathway segments that span the plurality of levels. The product information that matches the set of context search parameters is extracted from the product-to-chemical continuum. The callout-context pathway segments reduce processing resources and time needed to obtain the product information.

An improved and simplified system for densifying a cryogenic liquid for space vehicles is provided, which includes a heat exchanger having heat exchange tubes therein for receiving a flow of liquid from a storage tank, for example a liquid propellant in a vehicle storage tank. The heat exchanger is filled around the exchange tubes with a two-component bath, the volume of a primary component substantially exceeding the volume of a secondary component. The secondary component has a boiling temperature that is lower than the boiling temperature of the primary component, and both are lower than the boiling temperature of the cryogenic liquid. In one example, the liquid to be densified is oxygen, the primary component is liquid nitrogen, and a secondary component is liquid hydrogen. The secondary component is preferably injected into the heat exchanger in separate flows to prevent localized freezing of the first component. A manifold having a plurality of injectors may be used for introducing the second component to the heat exchanger. A control system receives inputs from one or more sensors within the heat exchanger and operates valves that control the flow of the first and second components of the heat exchange bath.

Methods and apparatus for liquid densification

A temperature-responsive actuator for a sealing assembly comprises first and second annular members each having a camming surface for engagement with one another, the first and second annular members being positioned against each other so that they are nested and together exhibit a height 'h' at ambient temperatures, the first annular member having a coefficient of thermal contraction less than the coefficient of thermal contraction of the second annular member so that when the thermal actuator is subjected to temperatures less than ambient temperatures, the first and second annular members contract different amounts such that the 'effective' height of the actuator becomes 'h+.tangle-solidup.h'.
