Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a liquid anesthetic agent container includes a base region, an interior of the base region configured to hold liquid anesthetic agent, an adapter region, and a capillary force vaporizer (CFV) housed in the adapter region. The adapter region includes a coupling end configured to couple to a patient breathing circuit to supply anesthetic agent vaporized by the CFV to a patient.

A gas-air mixer assembly is described that helps mix fuel and air within an HVAC system. The mixer assembly can also achieve lower pressure drops than seen in other solutions. A mixer assembly can comprise a mixer body through which air is supplied. An orifice body can extend into the stream of air within the mixer body and then point upstream. A tip of the orifice body, disposed in the airstream, can provide fuel through one or more orifices. The flow of air around the orifice body helps to cause mixing, as does an elbow bend in the mixer body, downstream of the orifice body.

An aerating and liquid agitating device to efficiently introduce high velocity, agitating air into a water line for mixing and aerating water tanks. An illustrative embodiment of the aerating and liquid agitating device includes a device fitting having an ingress end configured to be coupled to a liquid pump, an egress end and an opening between the ingress end and the egress end. The device fitting may be configured to accommodate flow of a liquid from the ingress end to the egress end. An air inlet fitting may extend through the opening in the device fitting and terminate inside the device fitting. The air inlet fitting may be defined by a terminal angled profile sloped between from about 35 to about 90. An air inlet hose may be coupled to the air inlet fitting. The air inlet hose may be configured to introduce air through the air inlet fitting into the device fitting.

Systems are provided for a mixer configured to be used in either an intake or exhaust passage. In one example, a mixer in the intake passage may be adapted to mix EGR with intake air and a mixer in the exhaust passage may be adapted to mix urea with exhaust gas.

An axial infuser assembly for use in a water treatment system is provided. The axial infuser assembly includes a first segment in fluid communication with a first inlet pipe. The first segment is further configured to receive a slurry flow. A second segment is in fluid communication with the first segment and is connected to an outlet pipe. The second segment receives the slurry flow from the first segment. A third segment is connected to the first and second segments and is also connected to a second inlet pipe. The third segment receives a motive flow. A jet assembly is in fluid communication with the third segment and conveys the motive flow in the third segment to the slurry flow. The motive flow exiting the jet assembly is configured to infuse with the slurry flow and further configured to urge the slurry flow into flowing raw, untreated water.

A mixer, a mixer assembly and a mixing method in which the mixer comprises a shell defining a first space, the first space receives engine exhaust, and the shell has a mounting area located on a wall of the shell; a doser mounting base arranged in the mounting area for mounting the doser, wherein the doser mounting base comprises a spray inlet as an inlet end for the spray that is sprayed by the doser entering the first space, and the doser mounting base further comprises a first swirl structure that surrounds the spray inlet to make the exhaust form a swirl around the spray inlet.

Provided is a chemical injection system for connection to a chemical tank and a process line. The system includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

A quenching process for quenching a flowing first fluid with a flowing second fluid may involve a first hollow pipe for containing the flowing first fluid and a second hollow pipe for containing the flowing second fluid; dividing the flowing second fluid into a first baffle flow along a first side of a longitudinal baffle and a second baffle flow along a second side of the longitudinal baffle within the second hollow pipe; providing a transverse baffle protruding from the longitudinal baffle for directing the first baffle flow from a first baffle flow outlet and the second baffle flow from a second baffle flow outlet in the second hollow pipe and into the flowing first fluid in the first hollow pipe; and configuring an area of the first baffle flow outlet area to be greater than or equal to an area of the second baffle flow outlet area.

A counterflow mixing device for a process chamber is disclosed, comprising an injection tube that introduces a fluid in a manner counter to a flow of a post-plasma gas mixture traveling downward from a plasma source. The invention allows for proper mixing of the fluid as well as avoiding recombination of generated ions and radicals.

A mixing spool is utilized to mix a liquid coagulant into water flowing through a large conduit. The mixing spool is inserted as a segment into the conduit. The mixing spool utilizes a pair of opposite facing nozzles which extend through a wall of the spool into the interior of the spool. The nozzles receive a pressurized liquid flow through a manifold. A chemical injection quill has an open end positioned between the opposite facing nozzles, wherein the chemical injection quill is configured to deliver the liquid coagulant into the water flowing through the conduit.
