  • Patent number: 6384276
    Abstract: The invention relates to a process for the preparation of high purity lactic acid from an aqueous solution containing said acid in the form of salt(s), characterised in that the aqueous solution is treated with a strong acid in order to liberate lactic acid in the free form and to produce salts of the corresponding strong acid, said salts of the strong acid are crystallised by evaporative crystallisation and lactic acid is recovered in the free form in solution.

  • Patent number: 6280985
    Abstract: The present invention relates to a process for the separation and purification of lactic acid from a fermentation medium wherein the lactic acid is totally or partially in the form of a salt or salts. The lactic acid producing microorganisms are separated from the other components of the fermentation medium. This solution is concentrated and then acidified to a pH below or equal to 3. The acidified solution is passed over a cation exchange resin to give a fraction that has maximum of 25% lactic acid salts relative to the dry weight of the solution. This fraction is subjected to bipolar fractionating electrodialysis. The resulting lactic acid is further purified, concentrated and then recovered.

  • Patent number: 5413325
    Abstract: A device for unpiling sheets one at a time from a pile of sheets placed perpendicular to a supporting surface, includes a pressure arm engaging a first face of the pile. A single friction drive roller has an axis perpendicular to the supporting surface, arranged at a predetermined distance from the supporting surface. The second face of the pile is engaged with the roller along a first edge. A low-friction abutment is arranged in the vicinity of the roller, separated from the supporting surface by the roller and has a surface parallel to the roller axis and offset relative to the roller. A pad is disposed substantially perpendicular to the supporting surface and is movable towards the abutment along a second edge located downstream of the first edge.

  • Patent number: 4829367
    Abstract: The present disclosure describes a color video signal encoding system for generating a NTSC color image composite signal for a television receiver. A luminance signal Y and two chrominance signals I and Q are modulated on a color subcarrier having a frequency F.sub.sc. The television receiver has an intrafield vertical sampling frequency F.sub.1. The encoding system comprises a first non separate two dimensional filter for low pass filtering the chrominance signal I, and a second non separable two dimensional filter for low pass filtering the chrominance signal Q. A third non separable two dimensional filter is used for band-stop filtering the luminance signal. The third filter has a stop band centered on .+-.F.sub.sc and .+-.F.sub.1 /2. The stop band has a shape similar to the shape of the band pass of the first filter so that said chrominance signals I and Q filtered by said first and second filter means can be inserted in the band covered by said stop band.
