Abstract: A method for the isolation of a substantially pure L-isomer of an amino acid from its D,L racemic mixture does not require the use of a resolving agent, the formation of a derivative of the amino acid or additional enzymic reactions. The method is based upon the concept of the equal saturation point wherein the L-isomer can be separated from the D-isomer by precipitation of the L-isomer when the relative concentration of the D-isomer is less than 7.0% or by precipitation of the D,L racemate when the relative concentration is greater than 7.0%. Selective crystallization through seeding allows for further isolation of pure L-isomer when its relative concentration in solution is very low.

Abstract: The method comprises, as a first stage, feeding a thermoplastic, thermosetting or elastomeric resin (10) in solid and preferably powder state into only a part (6) of the suitably preheated mould (2), this being achieved by separating the residual part in which a different colour is to be obtained, by the use of a special gasket (4). Said gasket is prepared by moulding, for example in the same mould (2), and is therefore able to perfectly follow the contour between the two colours. In the stage following the first filling, the mould is filled with powder material of the second colour and then emptied in accordance with the normal procedures of slush moulding. The mould (2), to which the two different colour materials have adhered to the required thickness, then passes to a further stage for completing gelling or fusion, before being cooled for extraction of the finished article. <IMAGE>

Abstract: Carbothermally reduce a metal oxide to its corresponding metal nitride or metal carbide powder in a vertical gravity flow reactor by adding precursor pellets containing the metal oxide, a thermally decomposed binder material and carbon or a source of carbon directly to a heated reaction zone within the reactor. The pellets form a pellet bed, the top of which must be maintained within the heated reaction zone. The binder material is a blend of wheat and corn starches, optionally in conjunction with another binder such as melamine. The binder material thermally decomposes to a carbonaceous residue which functions both as an additional source of carbon and as a binder for the precursor pellets. The reactor may be modified by adding an internal vent line to remove volatile materials from the heated reaction zone before they have an opportunity to condense on internal reactor surfaces.

Abstract: The invention relates to charge-coupled shift registers.
