Title: Process for the chemical resolution of 5-alkoxy-substituted(+_)-1,3-dimethyloxindolylethylamines
Inventor: LEE THOMAS B K
IPC: C07B57/00
Filed: 1990-09-18
Abstract: A process for chemically resolving a mixture of enantiomers of primary amines, such as enantiomers of 1,3-dimethyl-5-methoxyoxindolylethylamine, provides one of the enantiomers in the form of a tartaric acid salt. In carrying out the process, an enantiomeric mixture is contacted with a chiral acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The resulting precipitate can then be recovered. The chiral acid is selected from the group consisting of dibenzoyl-D-tartaric acid, dibenzoyl-L-tartaric acid, ditoluoyl-D-tartaric acid, and ditoluoyl-L-tartaric acid. The precipitates can be used in the synthesis of stereospecific forms of physostigmine.

Title: 3-and/or 4-substituted derivatives of quinic acid and a process for the production of 3-and/or 4-substituted derivatives of quinic acid
Inventor: HUYNH-BA TUONG
IPC: C07C67/29
Filed: 1993-07-16
Abstract: 3- or 4-Mono-, 1,3- or 1,4- or alternatively 3,4-disubstituted derivatives of quinic acid are prepared by reacting a derivative of a hydroxycinnamic acid, in which the phenol group(s) is(are) protected, with a quinic acid derivative so as to form an ester, taking advantage of the different reactivities of the OH functional groups in the 3 and 4 positions in order to carry out the esterification selectively under low temperature conditions, and then the protective groups are cleaved under controlled acidity and temperature conditions. These conditions prevent any degradation or isomerisation. The process makes possible the preparation of new quinides with a good yield.

Title: Downhole activatable annular seal assembly
Inventor: KREUGER SVEN
IPC: E21B21/00
Filed: 2004-06-23
Granted: 2008-01-16
Abstract: Devices and methods are described for establishing an effective annular seal about between an active pressure differential device and a surrounding wellbore sidewall. In other aspects, the invention provides a means of selectively activating such a seal during drilling operations or other operations wherein drilling mud is flowed through the drill string and returns through the annulus.

Abstract: PCT No. PCT/GB89/01497 Sec. 371 Date Jul. 23, 1991 Sec. 102(e) Date Jul. 23, 1991 PCT Filed Dec. 14, 1989 PCT Pub. No. WO90/07020 PCT Pub. Date Jun. 28, 1990.A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid while avoiding a significant loss of current efficiency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt. % N2O5 and less than 2 wt. % N2O4.

Granted: 1987-09-23
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.
