Abstract: A social matchmaking service selects matches of on-line game players based on personal/social characteristics of the players. The social matching service evaluates several criteria to obtain a list of available, socially compatible, game sessions. Criteria about the player include a player's friends, positive feedback about the player, negative feedback about the player, games completed with other players, players to avoid, and the player's gamer zone, country and language. Criteria about hosts of potentially compatible game sessions are also considered. Social matching utilizes a multi-pass approach, applying rules for prioritizing social criteria at each pass. The multi-pass approach starts with a narrow search and broadens the search at each successive pass. At each successive pass, sessions are added to the list of potential sessions until a reasonable number of sessions is achieved. Game sessions are assigned session values in accordance with affiliations between players.

Abstract: A degasser includes a vessel having a series of chambers. Liquid containing a gas is directed through the vessel and the chambers therein. A stripping gas is injected into the vessel and moves through the vessel in a counter-current direction relative to the flow of liquid. More particularly, the stripping gas moves from one chamber to another chamber in an upstream direction (relative to the flow of the liquid) and is mixed with the liquid in each chamber, causing gas in the liquid to be displaced. Displaced gas is vented from the vessel at a location near where the liquid enters the vessel.

Abstract: Devices for the removal of gases and/or volatilizable contaminants from liquids are described. In one example device, a liquid fluid containing dissolved gases and/or volatilizable contaminants are passed through at least one local constriction in a flow-through chamber at a sufficient pressure and flow rate to create cavitation bubbles in the liquid flow. The dissolved gases and/or volatilizable contaminants migrate into the cavitation bubbles. The velocity of the liquid flow is then reduced, which allows for the cavitation bubbles in the liquid flow to coalesce. The velocity of the liquid flow can then be reduced further, resulting in additional coalescing of the cavitation bubbles. The cavitation bubbles that contain the gases and/or volatilizable contaminants can then be separated from the liquid flow. The separation generally leaves a liquid flow product that may have a concentration of one or more gases or volatilizable contaminants lower than the starting liquid flow.
