Granted: 1999-08-02
Abstract: 2.1. A known device for photometric measurement of blood or blood plasma has a cuvette holder which is provided with one or more Küvette receptacles into which in each case one cuvette filled with an appropriate sample can be inserted from above. It has been necessary to date for the corresponding cuvette to be withdrawn upwards from the cuvette receptacle upon termination of the photometric measurement. During this time, no photometric measurement can be performed. It is therefore the object of the invention to shorten the temporal sequence of a photometric measurement. 2.2. For this purpose, the cuvette receptacle (3) is provided on its underside with a through opening which can end in a shaft (6). Furthermore, the cuvette receptacle (3) has a leaf spring (8) by means of which the sample to be measured can be locked in the cuvette receptacle (3). 2.3. The design permits a cuvette which is to be freshly inserted into the cuvette receptacle to be used to eject downwards the cuvette for which measurement has been concluded. A removal upwards is no longer required, and so the removal time is eliminated and the temporal photometric measurement is substantially shortened. <IMAGE>

Abstract: To produce methyl acetate, acetic acid, acetic anhydride in the same operation line, it is required to have five step : 1st step-methanol is changed to acetic acid and methyl acetate by gas phase CO carbonyl reaction under carbonyl catalyst and halide co-catalyst; 2nd step-from column bottom, acetic acid is seperated and recovered, low Bp.compound of co-catalyst and methyl acetate is seperated in column top section; 3rd step-seperated methyl acetate from 2nd step is distilled and unrecovered methyl acetate is sent to 2nd carbonyl reactor with co-catalyst; 4th step-by second carbonyl reaction, methyl acetate and co-catalyst from 3rd step is synthesized to acetic anhydride; 5th step - acetic anhydride is seperated from co-catalyst and seperated co-catalyst is recycled to 1st carbonyl reactor. Compared with a known process, this method is simple and increases productivity.

Title: Derivatives of advenced arylheptanne and its preparation
Inventor: AN BYUNG-JUN
IPC: C07C49/29
Filed: 1992-11-09
Granted: 1995-11-23
Abstract: The aryl heptenone derivative of formula(I) or formula(II) [R=substd. phenyl  is prepared by decarboxylation reacting a 5-ethoxy carbonyl-heptenone derivative of formula(III) with water and a lithium chloride in a solvent i. e. dimethyl sulfoxide at 150-200 deg. C for 10-20 hr. In the formulas, R is substd. phenyl, naphthyl, pyridyl, furyl thienyl, pyrrolyl, oxazolyl or thiazolyl; R1-R5 are each H, C1-4 alkyl, C1-4 alkoxy, halogen, trifluoromethyl or aryloxy. The aryl heptenone derivative (I) or (II) is used as an anti-cancer medicine.

Title: The method for preparing elastomeric yarn with high elastic
Inventor: KIM KWAN-TAE
IPC: D01F6/66
Filed: 1992-12-26
Granted: 1995-04-28
Abstract: A polybutylene terephthalate polyester as a hard segment and a polyoxybutylene glycol polyether as a soft segment were block copolymerized to give a polyether-ster copolymer. The copolymer was meltspun and slack heat- treated to show a shrinking percentage less than 20%. The obtained copolymer was drawn and secondary slack heat-treated to show a shrinking percentage less than 40% to give the high elastic polyester yarn.

Title: Liquid, low-colour polyisocyanate compositions, process for their preparation
Inventor: GEBAUER HERBERT
IPC: C08G18/80
Filed: 1993-01-06
Granted: 1999-11-15
Abstract: The invention relates to novel, pale, urethane-modified polyisocyanates or polyisocyanate mixtures from the diphenylmethane series, to a process for their preparation by reacting highly bicyclic polyisocyanates or polyisocyanate mixtures from the diphenylmethane series with highly functional polyether-polyols and optionally subsequently blending these modified products with polyisocyanates or polyisocyanate mixtures of the diphenylmethane series, and the use of the modified polyisocyanate mixtures in the production of pale, tough and rigid polyurethane foams.
