Abstract: A reactor with minimal dead volume especially suited to reverse-flow applications comprises: a) a reactor body; b) a first head engaged with said reactor body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the reactor body. The reactor is especially suited for use in a process for rapid stream-switching of at least two streams in a reverse-flow reactor.

Abstract: A service that provides for setting up game sessions for a plurality of game players. A number of game players that each have a computing device capable of playing a computer game are linked together by the service. The service allows a player to set up a common game session so that a subset of the players can simultaneously start playing the game at the same level. Additionally, the service allows game competitions to be structured and played among a subset of the game players.

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 method and system for accumulating data to match and matching a user, based upon a play style and/or personal attribute, in an online gaming environment is described. One aspect of the invention provides a matchmaking system that matches players based upon a play style of the players. The system matches players who are looking for games with players who prefer similar play styles. Similarly the system can match players based upon a personal attribute of the player. The system can be built into existing general skill level and technical capabilities based matchmaking systems to provide more user desired matchmaking parameters, allowing a user to choose based upon play style, personal attribute, general skill level, and/or technical capabilities.

Abstract: A collapsible wheelchair comprises a pair of interconnected side portions and a seat mounted on the side portions. The seat comprises a rigid base plate which is padded. A plurality of hooks are mounted on the rigid base plate for removably supporting the base plate on the side portions of the wheelchair by loosely hanging the hooks thereon. The hooks are vertically adjustable such that the elevation of the seat may be varied. The seat is removable whenever the wheelchair is collapsed by simply lifting the hooks from the side portions of the wheelchair.

Abstract: A foot support structure adapted to be used with a seat of an oscillating lawn chair swing is disclosed. The foot support structure is provided with impact absorbing means preferably secured parallel to and spaced away from at least one edge portion of said support means to cushion the impact of the foot support. The impact absorbing means preferably comprises polyethylene tubes arranged generally parallel to an axis of oscillation of the lawn chair swing.

Abstract: An integrated transistor circuit arrangement provides a multicollector transistor with Schottky diodes and ohmic connections selectively formed at the collector terminals. In the illustrative example, a vertical transistor is formed in an N-type epitaxial layer overlying an N+ substrate. A through-extending region of P+ material encircles the region of the epitaxial layer in which the vertical transistor is formed. The base of the vertical transistor is formed by the implanting of P-type impurity in a location spaced apart from the surfaces of the epitaxial layer. The resulting base has a symmetrical profile relative to the faces of the epitaxial layer. Therefore, the transistor may be operated with the collector at the surface without penalty of electrical operation. In the illustrative example, a PNP lateral transistor is utilized as a current source for the vertical transistor.
