Abstract: Process for the preparation of an optically active N-acyl-indoline-2-carboxylic acid in which a mixture of enantiomers of N-acyl-indoline-2-carboxylic acid is contacted with an optically active resolving agent and the optically active N-acyl-indoline-2-carboxylic acid is liberated from the resulting diastereomeric salt, as resolving agent use being made of a compound of formula 1, where R1 represents an alkyl group and R2 a (hetero) aryl group or where R1 and R2 together with the C atoms to which they are bound form a cycloalkyl group with 5-8 C atoms, fused with a (hetero) aryl group. Preferably, a mixture of enantiomers of an N-acyl-indoline-2-carboxylic acid is prepared in a process comprising the steps of Fischer indole cyclization of a 2-phenylhydrazone propionic acid or a derivative thereof in the presence of an acid catalyst, if necessary hydrolysis of the derivative to the corresponding acid, acylation at the N-position and reduction of the indole compound to the corresponding indoline compound, after which the resulting N-acyl-indoline-2-carboxylic acid is subjected to the resolution. The 2-phenylhydrazonopropionic acid or a derivative thereof is preferably obtained from phenylhydrazine and pyruvic acid or the corresponding derivative thereof.

Abstract: The invention relates to a method and a device for a graphical user interface for a navigation system. The graphical user interface includes a display having several groups of symbols with each group arranged in a unique pre-determined direction relative to a start position. A user manipulatable directional input device permits a user to select any one of the groups with a single keystroke. Once a group has been selected, the directional input device permits a user to activate any one of the symbols within a group with a single keystroke. An activated symbol can be selected with one keystroke by the user. Selection of a symbol then re-activates the start position.

Abstract: A method and apparatus are provided for generating bridge segments to enable editing jumps to be made from one A/V segment to another while handling timing and frame constraints imposed by the A/V segment compliance with coding conventions, such as MPEG. The bridge segment is constructed by copying data from the two sequences to be bridged, with some demultiplexing, decoding, remultiplexing and re-encoding of this data to maintain the validity of the edited data stream. Different procedures in terms of copying and/or re-encoding are applied in dependence on the picture encoding types at the source and destination of the edit via the bridging segment.

Abstract: A process for producing a biodegradable polymer having free carboxyl at the  omega -end charcterized by polymerizing a cyclic ester compound in the presence of a hydroxymonocarboxylic acid derivative having protected carboxyl or a hydroxydicarboxylic acid derivative having protected carboxyl, and then deprotecting the thus obtained polymer having protected carboxyl at the  omega -end. Use of the above process makes it easy to control the molecular weight of the target biodegradable polymer and the content of free carboxyl therein, thereby enabling the efficient production of a polymer having a high purity and being contaminated with littel catalyst remaining therein.

Title: Process for removing color bodies from hydrocarbon-based fuels using actived carbon
Inventor: JOSEPH JOSEPH T
IPC: B01J20/20
Filed: 2006-03-30
Abstract: An activated carbon, disclosed as useful in purification and decolorization of hydrocarbon fuel, particularly gasoline, is characterized by inclusion therein of polymerized phosphoric acid or reduced transition metals. Phosphoric acid may be added to a non-phosphoric acid-activated carbon (such as steam activated coal-based) prior to the subsequent heat treatment or one can take advantage of residual phosphoric acid present in, for example, a phosphoric acid-activated wood-based carbon. Similarly, transition metals such as copper may be added to an activated carbon in a salt form in addition to whatever is already present therein as impurities. The conversion of phosphoric acid to a polymerized phosphate content or reduction of transition metals to a reduced form results from the activated carbon having been treated with inert gas or carbon dioxide at from about 1200° F. to about 1800° F. for at least 5 minutes. Alternatively, the conversion of phosphoric acid to a polymerized phosphate content can occur during phosphoric acid activation of carbon at activation temperatures in the range of 1150°-1600° F.
