Embodiments of the method disclosed regard use of a torque sensor (e.g., transducer) and using the measured torque to detect the different fluid and mixing properties, conditions, and abnormalities in a mixing process. The torque produced in the mixing process relates to different fluid properties such as viscosity and density. It also relates to different mixing conditions such as presence of obstacles and changes or issues with gas sparging. Moreover, torque measurements enable determination of power transmitted to fluid by actual measurement, in contrast to using solely empirical impeller power number and speed, and allowing for actual mass transfer determination (i.e., gas transfer calculations).

A computer implemented method. The method includes generating, using a processor, a set of calibration data relating to a plurality of pigments that are present in a collection of coatings. Generating includes calculating an absorption/reflectance relationship of a plurality of samples coated with a plurality of the pigments, wherein calculating includes using a color matching calculation, and calculating a plurality of concentrations of a non-standard pigment. Generating also includes plotting a relationship between the concentrations and the absorption/reflectance relationships, and determining a correlation of the concentrations for a plurality of Fresnel coefficients relating to the samples. The method further includes determining, using the processor, a coating formulation of a target coating based on the correlation.

An airless pump container equipped with an impregnated member and an absorbing member includes: a container main body (10); a pushing plate (20); an impregnated member (30) installed inside of the container main body (10); a shielding member (40); a pump holder (60) coupled to the upper portion of the shielding member (40); an airless pump (50) installed on the inside of the shielding member (40) and the pump holder (60); an absorbing member holder (70) coupled to the upper end of the airless pump (50); an absorbing member (90); and a moving member (100) for fixing the absorbing member (90). The impregnated member is impregnated with content in a gel-state.

A mixer reactor apparatus comprising a plurality of baffles positioned within the reactor, the baffle comprising a hollow cylindrical structure with a substantially flattened baffle section between an upper section and a lower section. The apparatus further comprises a lever formed by a portion of the upper section bent at a perpendicular angle, the lever is configured to adjust an impact of the baffle by adjusting a position of the baffle member relative to an interior wall of the reactor.

A system for measurement of quantity (density) of particles/solid materials in wastewater, and dilution of particle quantity based on the intended application. Currently enabling quick and serial measurement of particle quantity in laboratory environment, this system is placed inside the desired step of the process of an industrial facility. This way, the system yields quick results and in turn reduces the analysis and evaluation costs.

A mixing unit (100) for mixing of fluids is disclosed. The mixing unit (100) includes a mixing chamber (102) for holding one or more fluids and a driving assembly (104) operatively engaged to the mixing chamber (102). The driving assembly (104) is configured to oscillate the mixing chamber (102) for mixing the one or more fluids. The mixing chamber (102) of the mixing unit (100) enables better mixing of fluids in a convenient manner. Further less amount of cleaning fluids may be only required for cleaning the mixing chamber (102) after the mixing process. The mixing unit (100) can be used for mixing amino acids with different fluids however this unit can be used for mixing other fluids as well.

A linear reciprocating actuator for mixing, agitating, separation, continuous sampling and/or harvesting or filtration, gas mixing, and various other applications. The actuator may have a housing closed on one end, and attached to a vessel in a hermetically-sealed manner such that it is part of the fluidic envelope of the vessel. An agitation device may be attached to a shaft which is partially surrounded by the housing, or the agitation device may surround the housing where the housing protrudes into the vessel. The actuator enables agitation of the contents of a hermetically-sealed vessel without mechanical coupling from outside the fluidic envelope of the process. The agitation device is solely acted upon by a magnetic field, is contained entirely within the fluidic envelope of the process, and is not attached to the vessel in any way. The magnetic flux which drives the agitation device passes through the housing.

The is provided an appliance including a food preparation container, an agitator assembly for attachment to a blending container, the agitator assembly including: an agitator nut configured to secure the agitator assembly to the blending container, an agitator base including at least one agitator blade mounted thereon and configured to be seated in the agitator nut prior to the agitator assembly being secured to the blending container, a groove formed in an inner wall of the agitator nut, and a seal having an outer periphery that when inserted into the groove secures the agitator base into the agitator nut.
