A storage drum assembly is described. The storage drum assembly is typically cylindrical, and comprises an outer wall portion, a top portion having a port or ports thereon, and a base having a generally conical sump portion with a frustum base. The storage drum assembly can also include an extended upper chime with a support lip, which enables attachments secured within the port or ports of the storage drum assembly to remain in place and protected from damage when multiple storage drums are stacked when not in use.

A container having a recess or a series of projections on the interior side of its wall to catch or restrain a magnetic stir bar during the pouring of contents from the container. The recess or series of projections may extend along the full interior circumference of the container or may be vertically aligned with a spout located at the opening of the container. One or more drainage channels extending from the recess towards the opening of the container may be provided to assist in pouring the contents out of the container.

A method for controlling pressure in a blending apparatus includes sealingly coupling a blade platform to a rim of a vessel including foodstuffs to form a blending chamber. The blade platform includes a blade assembly. The method includes injecting fluid via an opening defined within the blade platform into the blending chamber while the blade platform is sealingly coupled to the vessel. The injection of fluid causes a change in pressure in the blending chamber. The method includes rotating blades of the blade assembly to process the foodstuffs in the blending chamber. The method includes introducing air into the blending chamber to decrease a difference between the pressure within the blending chamber and a pressure external to the blending chamber. The method includes decoupling the blade platform from the rim.

Provided is a container for preparing a diluted solution of a biological sample to be used for biological sample analysis. Specifically, provided is a container for specimen dilution, including: an open; a first bottom; a second bottom formed on an inner side wall of the container; and a groove upwardly formed, on the inner side wall of the container, from the second bottom, in which the groove has a constant width equal to a width of the second bottom, or the groove has, at a lower end thereof, a width equal to the width of the second bottom and upwardly widens.

In one example, a build material supply system for additive manufacturing includes a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material.

In one example, a container includes expandable and contractible air free interior volumes joined by a passage through which liquid may pass from one volume to another volume, an inlet different from the passage through which liquid may enter into one of the volumes, and an outlet different from the passage through which liquid may leave another of the volumes.

Provided is a water carbonation unit including: at least one water feed and at least one pressurised carbon-dioxide feed; a merging duct extending between a first, closed end and a second end, the at least one water feed and at least one carbon-dioxide feed opening into said duct at said first end; said second end opening into a mixing chamber linked to a carbonated water outlet; the carbonated water outlet configured to restrict outflow of carbonated water from the chamber to thereby maintain pressure within the chamber while carbonated water flows out of the carbonated water outlet.

A conical mixer with two conical bodies that are sloped downward toward a discharge opening on a bottom, middle portion of the conical mixer. The conical mixer has a horizontally placed agitator axle with a plurality of agitator arms extending from the agitator axle. At least one paddle is attached to each agitator arms. As the agitator arms get closer to the middle, the length of the arms is increased. The conical mixer ensures proper mixing of the contents as well as using the slope of the conical bodies to assist in pushing the contents toward the discharge opening.

A reactor apparatus includes a reactor having a tubular shape, and a plurality of first cooling pipes arranged inside the reactor, for circulating a coolant. Each of the plurality of first cooling pipes has a serpentine portion that extends while repeatedly bending. The serpentine portion includes a plurality of extending portions that extend linearly or extend while curving, and a plurality of bending portions which couple ends of two adjacent extending portions, among the plurality of extending portions. At least two of the plurality of first cooling pipes have different distances from an inner wall surface of the reactor.

Liquid effluent treatment module comprising at least one tank portion suitable for receiving a plurality of packing elements that may receive a biological material, the tank portion defining a horizontal longitudinal axis and comprising at least one effluent feed, characterized in that the tank portion further comprises: at least one line for collecting treated effluent arranged in a central part of the tank portion and parallel to the horizontal longitudinal axis, at least one air injection line arranged in a lower part of the tank portion, off-centered and parallel to the line for collecting treated effluent so as to give rise to a spiral movement of the liquid effluents.
