Abstract: The invention provides a process for fractionation of compounds, which in essentially non-polar solvents form mixed or co-micelles, and hence cannot normally be fractionated by membrane filtration. By dissolving a mixture of such compounds in a solvent system in which selective micelles formation occurs, and contacting the solution under pressure with a semipermeable membrane to separate the mixture into a permeate and a retentate, fractionation of the compound mixture can be achieved, i.e. a fraction enriched in one of said compounds can be recovered from the permeate and/or retentate by removing solvent therefrom. The new process is in particular useful for fractionating phosphatides-containing mixtures into a fraction enriched in phosphatidyl choline by ultrafiltration of a solution of the mixture in a solvent system comprising an essentially non-polar solvent and a polar solvent, e.g. hexane-ethanol, etc. through a semipermeable membrane, and recovering a fraction enriched in phosphatidyl choline from the permeate. A fraction enriched in phosphatidyl inositol can be recovered from the retentate.

Abstract: In a combination of an amplifier (2, 5, 6) and a signal-dependent voltage supply source (16-23) coupled thereto a portion of the signal from the signal source (1) is applied by an amplifier (9) to a comparator (16), the output signal of which controls a limiter (20-21). A portion of the output signal thereof is applied as a feedback signal to a second input of the comparator (16) by means of a low-pass filter (22) and a feedback network (23) in series. The feedback loop thus formed is such that it oscillates at a comparatively high frequency. Then a signal-dependent modulation of the pulse width and/or the pulse density occurs at the limiter output. A supply voltage for the amplifier is derived from the output of the filter (22). Owing to the high feedback factor of the feedback loop at the signal frequencies the supply voltage can adequately follow the output signal of the amplifier, independently of component tolerances and any load variations.
