Übersetzung für "Phasenumkehr" in Englisch

During the addition of the water, a phase reversal occurred and an oil-in-water emulsion was formed.

Phase inversion takes place in the jet disperser 4.

Upon phase reversal, the same amplification as in the non-inverting mode is then obtained.

The emulsion polymer already contained the wetting agent for the phase inversion.

A phase reversal takes place at the half bit transition between two half bits belonging to one RDS bit.

So, by using light outside of the visible spectrum and reversing the phase, we get this.

The viscosity passes through a maximum during the phase reversal process.

In addition, the Lehle Dual SGoS also incorporates gold-plated phase-reverse and ground switches.

Emulsions with phase inversion are prepared using suitable pharmaceutically acceptable emulsifiers that are well known in the art.

The compositions may also be prepared under heat or through phase inversion.

One possibility is the phase inversion or reversal method.

Phase inversion can be observed due to the drop in homogenisation pressure.

A sharp drop in viscosity is characteristic of the phase inversion.

The Lehle P-Split II also features a gold-plated phase-reversing and ground switch.

A white gel was formed upon phase change of the W/O emulsion with an increase in viscosity in the mixture.

The W/O emulsion is thereby retained, that is to say no phase inversion takes place.

A sudden increase in viscosity occurs, brought about by the phase inversion and the rapid dissolution of the polymer.

According to the invention, the aqueous dispersion can also be converted by phase reversal from a water-in-oil to an oil-in-water emulsion.

Particularly fine dispersions are obtained when phase reversal is displaced into the shearing zone.

The conjugate was analyzed by reversed-phase HPLC on a NUCLEOSIL (high surface area spherical silica) C 18 250*4.6 column.

Through increasing of the amplitude of R 4, the time interval of phase reversal can be reduced to increase efficiency.

The pre-emulsion was passed through a multi-stage jet disperser at a pressure of 60 bar with phase inversion.

Other methods for the determination of the 1-octanol/water partition coefficient (POW) are the “shake-flask” method (2), and the determination of the POW from reversed phase HPLC-retention behaviour (3).

The invention relates to a process for the production of photographic emulsates consisting of dispersions of water-immiscible or water-insoluble particles in aqueous binder solution, characterized in that the entire non-aqueous phase is initially introduced at a temperature above the liquefaction temperatures of the aqueous and non-aqueous phases, after which a relatively small volume of aqueous phase is emulsified continuously or in portions into the non-aqueous phase by known methods and then more aqueous phase is introduced while emulsification is continued in such a quantity that the viscosity of the emulsion passes through a maximum (indicating phase reversal into an emulsion of non-aqueous particles in aqueous dispersion medium (FIG. 1)).

A reversal of the phases thus took place in this process, that is to say the aqueous phase which was initially present as the outer phase became the inner phase during dispersion.

The sinusoidal voltage at the output 6 of oscillator 4 is shifted in phase through 180° by means of a phase inversion (or reversal)--and attenuation installation 8, and is simultaneously attenuated to approximately half the amplitude. (The amplitude attenuation of apparatus 8 is variably adjustable.)

It is preferred that the conversion be performed in the presence of activators for the phase conversion of the W/O polymer dispersions or W/O emulsions of the metal salts, respectively.
