A distributor element comprising: at least two fractal plates each defining a level below an adjacent fractal plate, an uppermost fractal plate comprising a first number of first openings, each of the first openings surrounded at a lower side by one of a plurality of first walls and, in the first level between the first walls, one or more first hollow spaces defining one or more first fluid paths, a second fractal plate comprising a second number of second openings, each of the second openings surrounded at a lower side by one of a plurality of second walls and, in the second level between the second walls, one or more second hollow spaces defining one or more second fluid paths, the second number being higher than the first number, and each of the first fluid paths and each of the second fluid paths having substantially a same length.

There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.

The invention relates to an apparatus for aerating a pasty product. The apparatus comprises a housing (1) with an inlet (4) for the pasty product to be aerated and an outlet (5) for the aerated product.

The apparatus comprises at least a first set of a rotor and a stator (21) and a second set of a rotor and a stator (22). The apparatus further comprises a gas injector (6) for injecting, upstream of the first set of a rotor and a stator (21), a gas into the pasty product to be aerated.

The apparatus further comprises an intermediate mixing chamber (7) provided in the housing between the first and the second sets of a rotor and a stator (21,22). A secondary product introduction means protrudes into the intermediate mixing chamber (7) so as to issue into said intermediate mixing chamber (7).

A method for aerating a pasty product is also provided.

The invention discloses a low-energy consumption solvent dilution device for pre-treating samples comprising an accommodating unit, the accommodating unit including a case and an accommodating portion arranged inside the case; an input unit, which including an inlet, a second outlet and a third outlet extending into the case; a cleaning unit, which including a receiving assembly arranged below the second outlet and the third outlet, and a conveying assembly communicated with a receiving assembly. The input unit including a first tube connecting with the inlet, and a second tube and a third tube extending out of the second outlet and the third outlet, respectively.

The present invention completes dispensing and diluting the sample fixative in the box, the dispersion of the fixative is reduced. Avoid unnecessary contact for operators. It improves the safety and accuracy of the experiment, and significantly reduces energy consumption and labor costs.

Apparatus for mixing polymer, the apparatus comprising (i) a mixer housing including an internal chamber, said internal chamber having first and second sections in fluid communication with each other through a passageway; (ii) a first ram received in said first section; and (iii) a second ram received in said second section, where the apparatus is adapted to receive a composition including polymer within said internal chamber and move said composition between said first and second chambers through said passageway by operation of said first and second rams.

An apparatus to prevent formation of a vortex has a ring-shaped gasket having a bottom surface and a top surface; and a blade assembly mounted on the top surface and comprising a center portion and plural blades of a defined height. Each of the blades extend from the center portion to the top surface, with each pair of the plural blades defining a filter based at least in part on spacing between the pair of plural blades.

An apparatus includes a housing with an inlet for a pasty product to be aerated and an outlet for the aerated product. The apparatus includes at least a first set of a rotor and a stator and a second set of a rotor and a stator. The apparatus further includes a gas injector for injecting, upstream of the first set of the rotor and the stator, a gas into the pasty product to be aerated. The apparatus further includes an intermediate mixing chamber provided in the housing between the first and the second sets of the rotor and the stator . A secondary product introduction member protrudes into the intermediate mixing chamber so as to issue into the intermediate mixing chamber. A method for aerating a pasty product is also provided.

The material intake device includes a housing, an inlet port is provided at a first end of the housing, and an outlet port is provided at a second end of the housing, and the housing is further provided with an exhaust port used for exhausting an air in the housing; a separation plate is provided within the housing to isolate the inlet port from the exhaust port, an air inlet duct and an exhaust ductexhaust duct are formed respectively between the separation plate and sidewalls of the housing, the exhaust port is communicated with the exhaust ductexhaust duct, and an overflow port connecting the air inlet duct to the exhaust ductexhaust duct is provided between a bottom of the separation plate and the sidewalls of the housing.

A multi-component fluid mixing device for mixing two or more fluids which can be used with an applicator tool, such as a spray gun. The mixing device is used with a removable cartridge that is pressure fitted into the body of the mixing device using an actuation mechanism that elevates a cartridge engagement base to create a fluid-tight seal.

The present disclosure is directed to an agitating system having a sub-hopper configured to receive particulate material, an agitator disposed within the sub-hopper and configured to promote movement of the particulate material through the sub-hopper, and a deflector configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper. The deflector is positioned such that the agitator extends beyond a first distal edge and a second distal edge of the deflector along a lateral axis.
