    Abstract: The present disclosure is directed toward a suction nozzle operable to remove solid contaminants from a fluid without causing a substantial increase in fluid resistance. The suction nozzle has a vertical flow path, a contaminant precipitation recess opened upward under the vertical flow path, and a lateral flow path extending laterally from the vertical flow path at a position above the contaminant precipitation recess. The fluid sucked from a suction opening in the lower surface is led to the vertical flow path through the lateral flow path and flows upward through the vertical flow path to reach a connection port. With fluid flowing through the vertical flow path, solid contaminants contained in the fluid settle down by gravity and precipitate in the contaminant precipitation recess and are separated and removed from the fluid.

    Abstract: An apparatus for controlling an internal pressure of a hermetically sealed chamber (pass box 4) at a prescribed pressure level serves to relax pressure changes in the hermetically sealed chamber. The hermetically sealed chamber 4 is connected to an inlet passage 12 for supplying air from an external environment through an aseptic filter 14, an outlet passage 20 for discharging a gas through an aseptic filter 22, and an inlet valve 18 and an outlet valve 26 for selectively opening and closing the inlet passage 12 and the outlet passage 20, respectively. The apparatus also includes a controller 46 for controlling the inlet valve 18 and the outlet valve 26 to keep the internal pressure of the hermetically sealed chamber at a prescribed positive pressure level. An elastic membrane 48 of silicone rubber which is expanded or retracted depending on a change in the internal pressure of the hermetically sealed chamber to relax the pressure change is connected to the outlet passage 20 between the aseptic filter 22 and the outlet valve 26.

    Abstract: The present invention provides an improved solids removal and concentrating unit. The solids removal and concentrating unit comprises a tank, an inlet line, an outlet line, and a sludge removal line communicating with the tank. The solids removal unit further has a plurality of linear baffles positioned in the tank forming a baffle row, with the baffles being positioned in a substantially vertical orientation. Finally, the tank further has a plurality of baffle rows. The baffles operate to reduce the velocity of a carrier liquid behind the baffles. The baffles also operate to form slight vortexes in the carrier liquid behind the baffles and thereby facilitate the downward movement of solids.

    Abstract: The subject matter of this specification can be embodied in, among other things, a fluid flow trim apparatus includes an outer housing defining a cavity having an interior surface and an end wall having an orifice therethrough, a valve body comprising a first valve portion disposed at least partly within the cavity, the first valve portion and the interior surface defining a first fluid flow path, a second valve portion in contact with the interior surface and defining a second fluid flow path. A third valve portion is disposed at least partly within the cavity between the first and second valve portions. The second fluid flow path fluidically connects the third valve portion to a trim cavity. A filter media extends from the first valve portion to the second valve portion and divides a third fluid flow path fluidically connecting the first and seconds fluid flow paths.
