Method for producing dispersions of a defined particle size, a liquid mixture dispersion (Dm) being continuously separated into a coarse fraction dispersion (Dg) and a fine fraction dispersion (Df), comprising the following steps: A) continuously or discontinuously producing the mixed dispersion (Dm) in a pre-dispersion process, in which a particle mixture (Pm) of a disperse phase is mixed with a continuous liquid phase to form the mixed dispersion (Dm) and is intermediately stored in at least one mixing tank (Tm), B) introducing the mixed dispersion (Dm) from the pre-dispersion process into at least one continuously operating separating device (VT), C) separating the particle mixture (Pm) of the mixed dispersion (Dm) in the at least one separating device (VT) into coarse particles (Pg) of the coarse fraction dispersion (Dg) and into fine particles (Pf) of the fine fraction dispersion (Df) in accordance with a threshold value for the particle size, D) discharging the fine fraction dispersion (Df) from the at least one separating device (VT) into at least one storage tank (Tv), E) discharging the coarse fraction dispersion (Dg) from the at least one separating device (VT) into at least one disperser (DP), F) crushing the coarse particles (Pg) of the coarse fraction dispersion (Dg) in the at least one disperser (DP) into a dispersed particle mixture (PDm) and returning the dispersed particle mixture (PDm) into the at least one mixing tank (Tm), to the pre-dispersion process, and G) mixing the dispersed particle mixture (PDm) returned to the pre-dispersion process with the mixed dispersion (DM) produced in the pre-dispersion process in the at least one mixing tank (Tm).

A downhole tool includes a housing configured to be placed into a subterranean environment and a mixer disposed in the housing. The mixer includes a first inlet configured to receive a fusible metal or alloy component and a second inlet configured to receive a solid metal or semi-metal component. Additionally, the mixer includes a mixing chamber configured to mix the fusible metal or alloy component and the solid metal or semi-metal component to form a liquid or partially liquid alloy. Further, the mixer includes an outlet configured to discharge the liquid or partially liquid alloy into the subterranean environment. The liquid or partially liquid alloy is configured to harden into a solid alloy over time.

The present invention provides a method of producing an olive leaf extract that contains a high concentration of oleuropein. A method of producing an olive leaf extract comprises a first step of grinding dried olive leaves and a second step of mixing grapes with the ground olive leaves and then extracting an olive leaf extract using an extraction solvent. In the second step, the extraction solvent is water, alcohol, or a combination thereof, and extraction is performed at 70 C. or higher.

Disclosed herein are instruments and methods for performing both sample homogenization and sample clarification by centrifugation with a single instrument without transferring the sample to a new sample container and without removing or repositioning the sample container within the instrument. In some embodiments, the instrument may automatically perform centrifugation after homogenization. In other embodiments, the instrument may perform both homogenization and centrifugation simultaneously.
