Abstract: A fuel flow limiter assembly includes a limiter body forming a central bore, and including a shutoff piston within the central bore having a closing hydraulic surface exposed to a fluid pressure of the fuel inlet, and being movable from an open position, to a closed position based on a fuel pressure drop from a fuel inlet to a fuel outlet in the limiter assembly. A fuel filter is resident in the limiter assembly and supported in a connector coupled to the limiter body. The fuel filter is elongate and projects from the connector into a fuel flow path from the fuel inlet to the fuel outlet.

Abstract: A hydraulic actuator for a cryogenic pump is provided. The hydraulic actuator includes a piston. The hydraulic actuator also includes a base housing. The hydraulic actuator further includes a push rod assembly. The push rod assembly includes a tube guide. The push rod assembly also includes a push rod. The push rod is adapted to reciprocate within the tube guide. The hydraulic actuator also includes a sealing assembly having a hollow cylindrical configuration. The sealing assembly includes a first static seal portion. The first static seal portion being connected to the base housing. The sealing assembly also includes a second static seal portion. The second static seal portion is connected to the push rod. The sealing assembly further includes an expandable annular bellow extending between the first and second static seal portions. The sealing assembly is adapted to prevent flow of a first fluid in a first direction.

Abstract: An example multichannel video player includes a digital processor, random access memory coupled to the digital processor, a plurality of video outputs coupled to the digital processor and non-volatile memory coupled to the digital processor. The non-volatile memory includes program instructions which are transferrable to the random access memory and are executable on the digital processor. The non-volatile memory also includes a plurality of multichannel video tracks. An example method for providing a multichannel video system includes storing on a server a plurality of video tracks, where each video track includes a plurality of synchronized video segments, transferring at least one video track from the server to a player computer over the Internet and storing the at least one video track in non-volatile memory of the player computer.

Abstract: The present invention generally provides an anchor for providing an attachment point on a surface. In one embodiment, the anchor includes a center shaft having a first member and a second member pivotally coupled thereto. The center shaft has an attachment end and a piercing end. The piecing end is driven through the surface allowing the first and second members to pass therethrough. Once through the surface, the first and second members rotate away from the center shaft to an open position, thus preventing the anchor from disengaging the roof. A collar may be slidably disposed on the center shaft. The collar may be slid against the surface to lock the members in the open position.

Abstract: A coil-type vasoocclusion device (10) for establishing an embolus or vascular occlusion in a human or veterinary patient is adapted for introduction into the patient via a catheter (32). The device (10) first includes a coil (12) having proximal and distal coil ends (16,18) and a coil lumen (20). The device (10) also includes a core (22) disposed in at least part of the coil lumen (20), the core having proximal and distal core ends (24,26). Only one core end (24 or 26) is directly affixed to a respective end (16 or 18) of the coil (12); the other core end (26 or 24) is not directly connected to either end (16 or 18) of the coil (12). The core (22) is preferably nitinol in a superelastic state, being in other than its stress induced, martensitic condition. The device (10) can include a thrombogenic material (38) connected to or carried by the coil (12). The coil (12) is preferably adapted to achieve a suitable secondary shape (60) when deployed from the catheter (32).
