Patent DE-3701763-A1 (DE)
Inventor: LUYT BALTHASAR ANTONIUS GERARD
IPC: G11B20/12
Filed: 1987-01-22
Abstract: A method and apparatus for storing and reading digital information, in which the recorded information is protected by a double symbol correcting code involving interleaving between the codes and also employing an additional, optional error correcting code. The information is organized in sectors, which are arranged such that following the synchronization and header information sub-header information is provided to indicate different sub-modes of operation of the playback apparatus. During playback, when a first sub-mode indication value is detected, this means the sector contains further error protection information, that is, the optional error correcting code, for which purpose a special decoder is activated. When the sub-mode detector detects a second sub-mode indication value, this means that further user information is present at the location where the optional error protection information would have been, and the special decoder is not activated.

Title: Appliance for fractionating solutions
IPC: B01D57/02
Filed: 1987-10-23
Abstract: Appliances for the electrophoretic separation of solution fractions are known in principle and are used in practice particularly in the separation of proteins. The separation process can be carried out, for example, in a duct which is bounded on both sides by gel layers and through which an eluent-buffer solution flows, the gel layers being in contact with buffer solutions, one of which contains the particles to be fractionated. Under the effect of the electric field, some of the charged particles penetrate through the one gel layer and are discharged from the system with the eluent-buffer solution. An appliance according to the invention is characterised by three ducts (9, 10, 11) arranged underneath one another, the central duct being used to carry a starting solution, whereas the two on the side each serve to carry an eluent-buffer solution. Under the influence of an electric field, charged particles are transferred from the starting solution, according to their polarity, either into the one or the other duct, so that three fractions are obtained, namely one containing positively charged particles, one containing negatively charged particles and one containing electrically neutral particles. <IMAGE>
