A mixing and paint-making device and method for making paint are described. Embodiments of the paint-making device include a first and second palette hingedly coupled to a base. The base includes a paint pot shaking component configured to agitate and/or translate a paint pot. The paint pot shaking component includes a series of gears and pistons that interact to produce a shaking motion for a paint pot coupled to the paint pot shaking component. In one embodiment, the paint pot shaking component includes a crank gear adjacent a combination gear that contacts a slide crankshaft. The slide crankshaft is coupled to a slide crank arm that is secured by slide bracket coupled to the base. A paint pot harness holds a paint pot during agitation and moves in an upward and downward motion corresponding to the motion of the slide crank arm.

A unit for grinding biological samples, comprising a grinding device including at least two tubes having different volumes, suitable for being mounted on a support of the grinding device, each tube comprising an inner space having a height (h) along the axis of the corresponding tube, and being intended to contain samples to be ground, means for driving the support in a precession movement, the support having an axis the position of which varies by describing a cone, each tube being subjected to a movement (d) defined by the projection, onto the axis of said cone, of the distance between the extreme positions of a same point of the tube during the precession movement.

A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.

A system and a method that utilizes wet proppants when creating fracturing fluid by receiving wet fracturing sand at a surge tank, vibrating the wet fracturing sand located within the surge tank, liquefying the wet fracturing sand within the surge tank based on the vibration, and metering the liquefied wet fracturing sand from the surge tank to a blending tub.

Apparatuses and methods for generating a chemical gradient within a flow channel include providing at least one bubble support structure within the flow channel. A bubble support structure helps maintain a bubble at a predetermined location in flow channel when a fluid flow passes therethrough. Oscillations are induced in the bubble using acoustic waves, which may be provided by a piezoelectric transducer located proximate the flow channel. Two or more inlets provide fluids of different chemical compositions into the flow channel, and bubble oscillations are used to generate a dynamically controllable mixing process.

An ultrasonic mixing reactor configured for mixing of plant nutrients for greater absorption using cavitation. The reactor includes a venturi nozzle fluidly connected to a nozzle device having at least one annular shaped plate comprised of a plurality of apertures constructed and arranged to create cavitation. The nozzle device is fluidly coupled to a first ultrasonic reactor having a plurality of variable frequency ultrasonic transducers mounted within the first ultrasonic reactor for generating acoustic cavitation of the bulk mixed plant nutrients. The first ultrasonic transducer is fluidly connected to a second ultrasonic reactor having a plurality of variable frequency ultrasonic transducers mounted within the second ultrasonic reactor for generating acoustic cavitation of the bulk mixed plant nutrients. The second ultrasonic reactor discharge is fluidly coupled to a plate static mixer constructed and arranged to create hydrodynamic mixing.

The present application is directed towards systems and methods for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.

A bubble generator includes a diaphragm, a piezoelectric vibrator, and a light source. The diaphragm includes multiple micro apertures, a first surface to be in contact with the water in the water tank and a second surface to be in contact with the gas. The diaphragm transmits ultraviolet light. The piezoelectric vibrator vibrates the diaphragm. The light source emits ultraviolet light to the water in the water tank from a side region of the diaphragm near the other surface.

A light emitting device mixer includes at least two bowl feeders, each including a bowl capable of holding workpieces, and a driving unit capable of causing vibration to the bowl. The bowl feeders include a moving passage through which the workpieces may move from one bowl feeder to an adjacent bowl feeder.
