The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.

A thermokinetic mixer for melt mixing plastics waste includes a housing enclosing a mixing chamber, and a shaft protruding through the mixing chamber and connectable to a drive unit. In the mixing chamber, Y-shaped mixing blades protrude radially from the shaft, wherein the free end of the mixing blades protruding into the mixing chamber is cuboid, and the end opposite the free end of the mixing blades has two legs in each case having at least one through bore. The shaft has polygonal recesses, in which recesses the legs can be fastened by a fastener protruding through the through bores.

The invention relates to a piston, in particular, for use as a discharge and/or locking piston of a cartridge comprising a base body (25) having a lateral wall provided with sealants (14, 17) and a front-end wall having a vent (21). A locking element (18) is mounted rotatable in the vent (21), whereby a venting channel (23, 24) can be opened or closed by the relative rotation of the locking element (18) in the vent (21). Additionally, the invention relates to a cartridge configuration having such a piston.

A food waste treatment apparatus in accordance with an exemplary embodiment of the present disclosure includes: a housing including a food inlet opening at its top surface; an inner chamber where food introduced through the food inlet opening is collected; a stirring unit provided within the inner chamber and configured to stir food waste; an outer chamber positioned outside the inner chamber; and a rotation driving unit configured to rotate the stirring unit and the inner chamber, and the inner chamber and the stirring unit are rotated by the rotation driving unit in opposite directions.

A container for fermenting bio-degradable substances, the container comprising: a base and a wall, wherein an interior of the container is enclosed by the base and the wall; a rotatable agitator that protrudes into the interior and is supported in an upper bearing and a lower bearing in an installed position of the rotatable agitator in the container, wherein the rotatable agitator includes a shaft that is drivable by a drive, wherein at least one stirring paddle is arranged at the shaft and configured to co-rotate with the shaft so that substances arranged in the container are stirrable, wherein the lower bearing is arranged at the at least one base of the container and a bearing device located at a lower end of the shaft is supported in the lower bearing in the installed position of the rotatable agitator.

An analyte identifying and sorting apparatus for sorting a target analyte based on an identification result of analytes dispersed in a liquid. The apparatus includes an identification unit including an analyte storage section configured to store analytes dispersed in a liquid, a pressure control section configured to feed the liquid to a flow path provided to extend downward from the analyte storage section, a light irradiation section configured to irradiate light to the analytes, an optical information measurement section measuring optical information of the analytes, and a determination section determining whether the analyte is a target analyte or a non-target analyte based on the optical information. Also included is a sorting unit that includes a sorting nozzle connected to the identification unit and sorts a sorted solution containing the target analyte to the vessel, an effluent collection section having a suction nozzle to suck and collect an effluent involving an effluent discharged from a tip of the sorting nozzle, and a collection vessel configured to collect the sorted solution containing the target analyte. A moving unit moves the sorting nozzle and/or the collection vessel, a control unit moves the sorting nozzle and/or the collection vessel based on the optical information, and a stirring unit including a stirring member in an inner space of the analyte storage section.

A method for applying a curable building material, in particular in an additive method, including the steps of: providing at least two separate components of the building material; adding the at least two separate components into a mixing apparatus, in particular into a mixing chamber of the mixing apparatus, by a supply apparatus; mixing the at least two separate components in the mixing apparatus to obtain a curable building material in a set, cured state; supplying the set building material via a conveying line to a printing head, which is movable in at least one spatial direction, using a conveying apparatus; applying the set building material by the movable printing head.

A system for applying a building material including: a mixing device for mixing individual components of the building material into a curable building material; a pressure head which can be moved in at least one spatial direction and by means of which the workable building material can be applied; a delivery line, with which the curable building material can be conveyed from the mixing device to the pressure head; at least one delivery device for delivering the curable building material from the mixing device through the delivery line to the pressure head; a feed device, which is designed in such a manner that at least two separate components of the building material can be fed via at least two separate inlets into the mixing device, more particularly into a mixing chamber of the mixing device.

A stirrer assembly for use with a vessel, such as a keg, having an access opening. The vessel includes a cover that is adapted to close the access opening and has a through-hole therein. A stirrer assembly is adapted to releasably engage the through-hole and to be engaged by a motor. The stirrer assembly includes a driven shaft that extends in to a lower portion of the vessel with a paddle releasably mounted at a distal portion of the driven shaft.
