摘要:
The system includes a hair color packet assembly having several individual hair color packets and one developer packet, each packet having a pump for delivering selected amounts of material to a mixing assembly. A control assembly operable in response to a user's input controls each of the pumps to deliver selected amounts of color material and developer material to a mixing assembly which mixes the colors and the developer and delivers it to a brushhead/distributor, which has openings through which the selected hair color formulation is delivered. The brushhead/distributor is mountable in a handle having a motor which drives the brushhead/distributor in a linear oscillating manner.

The present invention relates to an apparatus and method for mixing and atomizing a hydrocarbon stream using a diluent/dispersion stream. The apparatus comprises an inner conduit having an inlet for receiving the diluent/dispersion stream; an outer conduit having an inlet for receiving the hydrocarbon stream and an outlet for dispensing a mixture comprising the hydrocarbon and the dispersion/diluent streams; said outer conduit concentric to the inner conduit to define at least a first annular space and a second annular space; the first annular space being located downstream of the inlet of the outer conduit, said first annular space enabling formation of a thin film of the hydrocarbon stream between an outer surface of the inner conduit and an inner surface of the outer conduit; the second annular space being located downstream of the first annular space, said second annular space having a width greater than a width of the first annular space; and the inner conduit located at about the second annular space comprises a first set orifices disposed on a periphery thereof for dispensing a first portion of the dispersion/diluent stream into the thin film of hydrocarbon stream to cross-shear the thin film and form the mixture comprising the hydrocarbon and the dispersion/diluent streams.

A microfluidic device for on-site quantitative detection of marijuana in body fluids has a body fluid collecting reservoir for receiving a body fluid and an anti-THC antibody reservoir that retains anti-THC antibodies. A first micromixer receives the body fluid from the body fluid collecting reservoir and the anti-THC antibodies from the anti-THC antibody reservoir to form a sample mixture. The device further comprises a fluorescein-THC conjugate reservoir that fluorescein-THC conjugate; a second micromixer that receives the sample mixture and the fluorescein-THC conjugate to form a test mixture; and at least one light source to emit an excitation wavelength and at least one detector to receive an emission wavelength.

摘要:
A method for mixing at least two materials is provided. The method comprises introducing the at least two materials into a physical system and combining the at least two materials to form a mixture thereof. The method also comprises independently controlling a desired characteristic of the mixture and a desired parameter of the physical system, wherein the controlling is based in part on estimating a disturbance, wherein the estimating the disturbance is based on processing an error term determined by subtracting a modeled parameter of the physical system from a corresponding sensed parameter of the physical system.

A method for producing powder paints which comprises the steps of: a) preparing a paste comprising at least one thermosetting plastic resin, at least one curing agent, at least one pigment and water and making the paste flow in the form of a thin layer and under conditions of high turbulence in contact with a wall at a predetermined temperature; b) drying the paste by making it flow into a thin and turbulent layer in contact with a heated wall and optionally with a flow of heated gas.
摘要:
A method of producing ceramic slurry capable of producing uniformly dispersed ceramic slurry without excessively damaging a ceramic powder, and a method of producing a ceramic slurry composition used for producing a multilayer ceramic electronic part, from which an undissolved binder is precisely removed. Also provided is a method of producing a ceramic green sheet, and a method of producing a multilayer ceramic electronic part. A ceramic powder having an average particle diameter of about 0.01 to 1 &mgr;m is mixed with a dispersion solvent (solvent) and disintegrated by a medium-type dispersion method using a dispersion medium such as balls, beads, or the like to obtain mixed and disintegrated slurry, followed by high-pressure dispersion under a pressure of about 100 kg/cm2 or more. The ceramic slurry composition contains a ceramic powder, a dispersant, a binder, and a solvent, wherein a binder solution prepared by mixing a solvent and the binder to form a solution, and dispersing the binder under a high pressure of about 100 kg/cm2 or more is used as the binder to decrease the content of the undissolved binder.
