An exhaust apparatus using a gas curtain instead of a mechanical opening / closing structure is provided. The exhaust apparatus includes: a first region; a second region connected to the first region; a third region connected to the first region; and a first gas line connected to the second region, wherein when gas is supplied to the first gas line, the first region does not communicate with the second region but communicates with the third region.

Various systems, methods, and devices are provided for focusing particles suspended within a moving fluid into one or more localized stream lines. The system can include a substrate and at least one channel provided on the substrate having an inlet and an outlet. The system can further include a fluid moving along the channel in a laminar flow having suspended particles and a pumping element driving the laminar flow of the fluid. The fluid, the channel, and the pumping element can be configured to cause inertial forces to act on the particles and to focus the particles into one or more stream lines.

A connector for interconnecting two building members together. The connector, in one embodiment, includes first and second plates secured together. Each plate includes one or more elongated slots wherein the elongated slots of one plate are oriented at an angle of approximately 90° with respect to the slots formed in the other plate. Fasteners extend through the slots in the plates and connect the plates of the connector to two building members such as a horizontal building member and a vertical building member. Once connected, one of the building members is free to move with respect to the other building member while the connector is connected to the two building members. In another embodiment, the connector is slidable within a track. In this embodiment, a portion of the connector extends from the track and connects to one of the building members while the track connects to the other one of the building members.

A plurality of studs (14) are spaced apart relative to each other. Upper end portions (32) of the studs fit into an upper channel space (22) and lower end portions (34) fit into a lower channel space (30). The lower channel space (30) is defined in part by a pair of spaced apart sidewalls (24, 26). Screw fasteners (52) extend through the sidewalls (24, 26) and connect them to the lower end portion (34) of the stud (14). The studs (14) have upper ends that are spaced from a web (20) forming the upper boundary of the upper channel space (22). Vertical elongated slots (48, 50) are provided in the sidewalls (38, 40) of the studs (14). Screw fasteners extend through the sidewalls (16, 18) of the upper channel member (10) and then extend into and through the slots (48, 50). The heads of the screw fasteners (52) bear against the sidewalls (16, 18) when the screw fasteners (52) are tightened. This firmly connects the screw fasteners (52) to the sidewalls (16, 18), but there is no connection of the screw fasteners (52) to the upper end portions of the studs (14). When the screw fasteners (52) are tightened, there is no clamping action between the heads (54) of the screw fasteners (52) and the upper end portions (32) of the studs (14). As a result, the studs (14) are completely free to move up and down relative to the upper channel member (10), within limits established by the lengths of the slots (48, 50).

A missile flow line is assembled in a frac manifold to manifold the discharge from a plurality of pumps. The missile comprises at least two junction fittings joined by a flange union to at least one spooled pipe to form a conduit. The junction fittings comprise a fitting body having a primary bore and at least two feed bores. The primary bore extends axially through the body between primary union faces adapted for connection to a flowline component by a flange union. The feed bores extend radially through the body from a feed union face to an intersection with the primary bore. The feed union faces are adapted for connection to pump discharge lines by a flange union. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore.

An aseptic fluid connector having a first connector including a first fluid passageway for receiving a fluid therein; a first port in fluid communication with the first fluid passageway for passage of the fluid therethrough; and a first deflecting member. The first deflecting member includes a first engaging portion radially spaced relative to the first port, and a first valve movable between a closed position and an open position with movement of the first engaging portion between a non-deflected position and a deflected position, respectively. In the non-deflected position, the first valve is located in the closed position forming a fluid-tight seal between the first valve and first port and preventing the passage of fluid therethrough, and in the deflected position, the first valve is located in the open position allowing the aseptic passage of fluid through the first port.

A tubing fitting for use in microsurgery including a female tubing fitting and a male tubing fitting. The female tubing fitting has an external surface with a pair of opposing projections disposed thereon and an internal bore. The male tubing fitting has a second internal bore and a collar at least partially surrounding the second internal bore. The collar has an internal surface with two pairs of opposing sloping ramps disposed thereon. The pairs of opposing sloping ramps are arranged so as to create a pair of opposing spaces for removably receiving the pair of opposing projections.
