MIXING DEVICE AND METHOD OF MIXING FLUIDS

Номер: US20220001343A1
Автор: Neverov Daniel A
Принадлежит:

The present invention is a method of mixing various viscous fluids. The mixing device is comprised of a shroud with helical blades inside connected to the central shaft and the shroud in spiral direction. By rotating the device in the fluid or paint, helical blades create a vortex like movement of the fluid and thus create suction of the fluid through the shroud, mixing viscous fluid at a greater rate. Field test showed that the devise is very effective in mixing viscous fluids by braking solids in the paint/fluids and lifting the settlements from the bottom of a container due to the radial and axial movement of the fluid. Device was found very easy to use due to the fact that the kickback of the mixer was minimized. It also showed that the splatter of paint was almost eliminated in the open container. 11. Reduction in RPM, splatter and oxidation of the fluids.2. Decreasing the kick-back of the mixer during the process of mixing.3. Creating radial and axial mixing simultaneously, thus mixing solids and resins in fluids at a greater rate.. The improvements of the said device are—faster, thorough and at a greater rate of mixing fluids. Due to the design of the helical blades placed inside the shroud, the mixer can mix the fluids in two combined methods of mixing, radial and axial, simultaneously. The design and placement of the shroud over the blades creates a jet like mixing effect and serves as elimination of kick-back of the mixer during the mixing process. The combination of the shroud and the helical blades internally positioned between the shroud and the central shaft create an improved mixing method of fluids: Provisional Patent Application No. is 62/870,158, filing date Jul. 3, 2019. Filing license granted Jul. 9, 2019 Country code and number U.S. 62/870,158.Field of inventionThis present invention relates to a method of mixing paint and other various viscous fluids by rotating a helical bladed mixing device.The mixing of viscous fluids is more complicated ...

The present invention generally relates to droplets and/or emulsions, such as multiple emulsions. In some cases, the droplets and/or emulsions may be used in assays, and in certain embodiments, the droplet or emulsion may be hardened to form a gel. In some aspects, a heterogeneous assay can be performed using a gel. For example, a droplet may be hardened to form a gel, where the droplet contains a cell, DNA, or other suitable species. The gel may be exposed to a reactant, and the reactant may interact with the gel and/or with the cell, DNA, etc., in some fashion. For example, the reactant may diffuse through the gel, or the hardened particle may liquefy to form a liquid state, allowing the reactant to interact with the cell. As a specific example, DNA contained within a gel particle may be subjected to PCR (polymerase chain reaction) amplification, e.g., by using PCR primers able to bind to the gel as it forms. As the DNA is amplified using PCR, some of the DNA will be bound to the gel via the PCR primer. After the PCR reaction, unbound DNA may be removed from the gel, e.g., via diffusion or washing. Thus, a gel particle having bound DNA may be formed in one embodiment of the invention. 120-. (canceled)21.

Bead incubation and washing on a droplet actuator

Номер: US20190011443A1
Автор: Arjun Sudarsan, Michael G. Pollack, Ramakrishna Sista, Vamsee K. Pamula
Принадлежит: ADVANCED LIQUID LOGIC INC

Methods are provided for separating magnetically responsive beads from a droplet in a droplet actuator. Droplet operations electrodes and a magnet are arranged in a droplet actuator to manipulate a bead-containing droplet and position it relative to a magnetic field region that attracts the magnetically responsive beads. The droplet operations electrodes are operated to control the droplet shape and transport it away from the magnetic field region to form a concentration of beads in the droplet. The continued transport of the droplet away from the magnetic field causes the concentration of beads to break away from the droplet to yield a small, concentrated bead-containing droplet immobilized by the magnet.
