摘要:
The present application is directed towards systems and methods for continuously reacting a combination of materials by use of an acoustic agitator and a continuous process vessel. The system can react, fluidize, mix, coat, dry, combine or segregate materials. The continuous processing system can include an acoustic agitator capable of being removably coupled to a continuous process vessel. The continuous process vessel can include a first inlet for introducing at least one process ingredient, a plurality of plates configured for directing a flow of the at least one process ingredient through the continuous process vessel and capable of transferring acoustic energy generated by the acoustic agitator into the at least one process ingredient, an outlet for discharging a product of the at least one process ingredient, and a fastener for removable coupling the continuous process vessel to the acoustic agitator.

A biocompatible and biodegradable material is applied to a tissue region, e.g., to seal a vascular puncture site, or to arrest the flow of blood or fluid from body tissue, or to arrest diffuse bleeding. The material preferably includes a protein comprising recombinant or natural serum albumin, which is mixed with a polymer that comprises poly(ethylene) glycol (PEG), and, most preferably, a multi-armed PEG polymer.

A mixer for a vehicle exhaust system includes a mixer body defining a mixer central axis and having an inlet configured to receive engine exhaust gas and an outlet. The mixer further includes an upstream baffle positioned within the mixer body and a downstream baffle positioned within the mixer body to be spaced from the upstream baffle in a direction along the mixer central axis. A doser defines a doser axis and is positioned to spray a reducing agent into an area between the upstream baffle and the downstream baffle such that a mixture of reducing agent and exhaust gas exits the outlet. The mixture moves through a rotational flow path that is at least 360 degrees before exiting the outlet.

摘要:
A fluid separation device and in-line orifice mixer system is disclosed. The fluid separation device utilizes a syringe (10), which is used for obtaining a fluid sample such as blood, in a centrifugation device; and further utilizes the syringe as a source of a separated fluid portion for storage and transfer for subsequent applications. The syringe containing the separated portion source, and a second syringe (50) containing a second source, are connected to the in-line orifice mixer device. The mixer device (44) comprises a plurality of orifice walls (58) each providing an orifice nonaligned with adjacent orifices to homogeneously mix the plurality of components. The mixer device may further comprise an exit orifice wall with one or more orifices for discharge of the homogeneous mixture.
