Patent DE-4040447-A1 (DE)
Inventor: LOTZE MARION DR
IPC: C07F1/12
Filed: 1990-12-18
Abstract: The preparation of gold(I) mercaptides, which is known per se, by reaction of a gold(I) halide-dialkyl sulphide complex, which is obtainable from gold(III) halide or gold(III) halogen complex and a dialkyl sulphide, with a mercaptan can be improved if a (C1- to C8-)-alkylmercapto-(C3- to -C6-)amino acid or a water-soluble salt thereof is used as the dialkyl sulphide. The advantages of the dialkyl sulphides according to the invention compared with the dialkyl sulphides employed hitherto lies in their water-solubility and insolubility in organic solvents and thus a simplification of the purification of the gold(I) mercaptides, irrespective of their structure and solubility. A further advantage of the alkylmercaptoamino acids, D,L-methionine being particularly preferred, is their much lesser odour compared to the di(C1-C8)alkyl sulphides previously preferably used.

Title: Automatic procedure for handling bottles in champagne mfr. - by taking bottles from storage container to treatment containers in gps. so bottles have same orientation
Inventor: THIERION MICHEL
IPC: C12G1/09
Filed: 1991-06-13
Abstract: Bottles (7) are transferred from a storage container (6), in which they face in opposing direction, to a treatment container (8,9) in which they all face in the same direction. At least two treatment containers are used with each storage container. A number of bottles of similar orientation are taken from the storage container and transferred to a treatment container in which this orientation is maintained. This procedure is then repeated for bottles having the opposite orientation. During the transfer the bottles have their necks inclined downwards at up to 45 degrees. An intermediate table (11,12) may be used on which the sets of bottles taken from the storage container are placed and from which the required number of bottles for the treatment container can then be selected. USE/ADVANTAGE - Used in wine mfr. by the champagne method for loading bottles into the treatment containers in which they undergo 'remuage' - i.e. collection of the deposited yeast in the necks of the bottles. The yeast depositing process is not disturbed during the loading procedure, and a suitable speed of loading is achieved, in spite of the mechanical impact necessarily involved in an automatic handling system.

Title: Time-saving method for fixed immunoassays in diagnostics - comprises covering pin-surfaces with the substrate to be measured and immersing the pins in plate with complementary cavities
Inventor: FAULDE MICHAEL DIPL BIOL DR
IPC: G01N33/543
Filed: 1991-06-19
Abstract: A fixed-phase enzyme-immuno assay method for routine diagnostics comprises (i) the immersion of pins of a grid-plate whose surfaces support bound antigen (Ag) or antibody (Ab) to be measured, in a plate with complementary cavities, these cavities being filled with cognate Abs or Ags; (ii) washing of the pins in the cavities with wash soln.; (iii) incubation of the pins in cognate Ag-enzyme or Ab-enzyme solns. (iv) washing as in (c); and (v) measurement of the fixed enzyme-Ag or enzyme-Ab. Also claimed is an assay set of pin- and cavity plates, which pref. can only interlock in a single orientation and which pref. consists of strips of 8 pins. USE/ADVANTAGE - Compared to micro-titre plates used in the prior art for routine diagnostics the diffusion speed of the reactants is decreased and the washing steps are reduced to a dip of the pins into wash solns., abolishing the time-consuming prior art steps of removal of fluid from individual wells. The time saving is about 100 minutes. As all pins are immersed into the cavities for identical times, the time differences of the prior art caused by pipetting times are omitted. Therefore, the results are reproducible and can be standardised.
