Abstract: Aus Lactobacillen, insbesondere aus Lactobacillus kefir wird eine zur Reduktion von Acetophenon zu R(+)-Phenylethanol in Gegenwart von NADPH befähigte Phenylethanol-Dehydrogenase isoliert. Diese ist zusätzlich zur Reduktion von aromatischen, alicyclischen und aliphatischen Ketonen wie insbesondere von p-Brom-acetophenon, Methylcyclohexanon, Aceton, Methyl-hexylketon, 4-Phenyl-2-butanon, 1-Phenyl-1,2-propandion, Ethylpentylketon, Pinakolin, Propiophenon, p-Chlor-acetophenon befähigt. Durch EDTA erfolgt eine rasche Desaktivierung, jedoch haben übliche Inhibitoren, Chelatoren und SH-Schutzreagenzien nur einen geringen Einfluß auf die Aktivität. Der KM-Wert für Acetophenon liegt bei 6 x 10<-><4> M. Die Dehydrogenase ist für die enzymatische Reduktion von Oxo-Verbindungen unter Bildung optisch aktiver Hydroxy-Verbindungen in Gegenwart von NADPH geeignet, wobei vorzugsweise mit gleichzeitiger NADPH-Regenerierung innerhalb der Reaktionsmischung, insbesondere mittels Glucose-6-P/Gluxose-6-P-Dehydrogenase oder Isopropanol, gearbeitet wird. <IMAGE>

Abstract: A massively parallel processing system comprising a plurality of processing nodes (10) controlled in parallel by a controller. The processing nodes are inter-connected by a plurality of communications links. Each processing node comprises a memory (12), a transposer module (21) and a router node (15L-15H). The memory stores data in slice format. The transposer module is connected to the memory and generates transpose data words of selected ones of the data slices from the memory. The router node (15L-15H) is connected to the transposer module (21) and to the communications links and transfers transpose data words over the communications links to thereby transfer the data slices between processing nodes. Finally, the controller controls the memories (12), transposer modules (21) and router nodes (15L-15H) of the processing nodes (10) in parallel, to facilitate transfer of data slices among the processing nodes in unison.

Abstract: A method of mass spectrometry and a mass spectrometer for the analysis of a sample (5), the mass spectrometer comprising means (1) for producing ions (6) from the sample and a magnetic sector (12) for analyzing the ions, wherein the magnetic field of the magnetic sector is generated by passage of a magnet current controlled by a digital control signal representative of a sequence of integers generated by a computer (15). According to the invention, means (16,17,18) are provided for generating the magnet current in exponential relation to the sequence of integers. In contrast to prior spectrometers, the invention provides peak switching and mass selection across the mass range with a constant number of integer steps per mass peak, thereby facilitating the digital selection of any particular mass peak, particularly those at low mass.

Abstract: Disclosed is a volume managing system for computer storage devices. Physical volumes are logically partitioned, with multiple copies of data being maintained for system recovery purposes. A scheme for monitoring, updating, and recovering data in the event of data errors is achieved by maintaining a volume group status area on each physical volume, the status area reflecting status for all physical volumes defined for a given volume group. Updates to this status area occur serially, thereby protecting against all volumes becoming corrupted at once. A method of updating subsequent status changes, while the first status change is still in progress, provides for improved system throughput.

Abstract: A reverse osmosis system includes a sediment filter which cleans feed water from a source and from which that feed water is fed to a reverse osmosis membrane filter. Permeate from the latter is fed to a bladder within a storage tank. Concentrate from the membrane filter is fed to and used within the storage tank as squeeze water for the bladder. When a faucet that delivers permeate to the user is open, squeeze water is used to cause permeate to flow out of the storage tank through an impurity filter to supply the faucet. A valve unit is included to control the amount of squeeze water fed to the storage tank and to regulate permeate flow so that the water outletted from the faucet remains at a constant pressure and provides relief as against overpressure in the system. A proportioning valve within the valve unit serves to maintain at all times a constant ratio of concentrate to permeate flow through the membrane filter for adequate cleansing of the membrane. Also included are input-side and output-side flow monitors which provide signals to a processor that serves to indicate the status of filter conditions. There also is an advantageous faucet assembly for controlling the delivery of permeate to the user with flexibility and convenience.

Abstract: This invention relates to an alkaline battery in which hydrogen gas evolution and deterioration of battery performance can be prevented by using a collector having an outermost layer coated with zinc or metal having a higher hydrogen overvoltage than that of zinc and adding an inhibitor selected from an indium compound, lead oxide, a hydroxide of alkaline earth metal and polyoxyethylen alkylamide to an electrolyte solution or a negative electrode active material. 
     According to the present invention, it is possible to manufacture an alkaline battery in which evolution of hydrogen can be restrained without involving deterioration of battery performances. Especially, the present invention is effective in a coin type and a button type battery which is sensitive to the evolution of gas and is required to have high performance. 
     Further, the inventive collector which is plated with zinc alloy more than 3 µ m in thickness and used for low drain such as watches can attain a capacity equivalent to or more than that of a battery using amalgamated zinc. Further, watches loaded with the inventive alkaline batteries which are discarded do not pollute the environment, as they do not include mercury to be a pollution material.

Abstract: A process for the production of methyl formate by carbonylation of methanol in the presence of sodium methoxide or potassium methoxide as a catalyst is improved by reduction of the catalyst consumption and intensification of the process. For this purpose, a certain amount of sodium oxaperfluoro-alkanesulfonate or potassium oxaperfluoroalkanesulfonate and up to 10% by weight of strongly organic bases are added to the mixture for carbonylation. The reaction is carried out in a reactor having a circulation pump. The sodium salts, which are reaction products of the sodium methoxide, are removed by means of a filter. The filtrate is separated with the aid of rectification and the bottom product again subjected to carbonylation. The methyl formate results as the distillate, a high yield being achieved.
