Abstract: A charge is injected at an intermediate point in a cell assembly and two phases alternate, with a first phase of duration t1 where the lighter solvent is injected at a first end of the device and a first component is received at the second end, and a second phase of duration t2 where the heavier solvent is injected at the second end and a second component is received at the first end : The charge in liquid solution has at least two components (A, B) of different partage coefficients such that they are entrained at unequal speeds respectively by a light solvent and a heavier solvent, in a device comprising at least one liquid-liquid centrifuge chromatography column (col) made by interconnection in series of at least one separation cell assembly (CE). The durations t1 and t2 and the rates of injection of the solvents are adjusted as a function of the components of the mixture, to obtain an optimal separation. A number of separations in cascade are used to isolate the components from each other in a mixture of more than two components. Two optical isomers are separated by injecting into a first device a charge containing the optical isomers and a chiral selector to obtain a first isomer and a mixture of the second isomer and the chiral selector. The mixture is then injected into a second device to separate the second isomer from the chiral selector. The charge can be injected continuously or discontinuously. An independent claim is made for a device to carry out the above process, which includes column(s) (col), a chain of separation cells (CE), a charge injection pump (P1), valves (V1, V2), receivers for the two separated components (FA, FB), and solvent injection pumps (P2, P3) for the lighter solvent (L) and the heavier solvent (l). The valves are alternated to change between the two phases. For mixtures with more than two components, at least two separation columns in cascade are used.

IPC: G10L21/038
Filed: 2004-06-25
Abstract: The present invention relates to a method of encoding and decoding an audio signal. The invention further relates to an arrangement for encoding and decoding an audio signal. The invention further relates to a computer-readable medium comprising a data record indicative of an audio signal and a device for communicating an audio signal having been encoded according to the present invention. By the method of encoding, a double description of the signal is obtained, where the encoding comprises two encoding steps, a first standard encoding and an additional second encoding. The second encoding is able to give a coarse description of the signal, such that a stochastic realization can be made and appropriate parts can be added to the decoded signal from the first decoding. The required description of the second encoder in order to make the realization of a stochastic signal possible requires a relatively low bit rate, while other double/multiple descriptions require a much higher bit rate.
