    摘要： The present invention relates to a method of inhibiting the formation of and/or breaking of preformed mercury butter in chlor-alkali cells. The method comprises introducing at any one of the numerous stages of the electrolytic process an aqueous solution of a surfactant material which enables the interfacial tension of the sodium-amalgam interface to be increased to or maintained above a value of 180 dynes/cm. The surfactants may be extracts of decaying vegetation, solutions of carboxylic acids or chlorohydrocarbons. Extracts containing lignite or humic acids are most effective.

    摘要： The present invention relates to an electrochemical process for synthesizing carboxylic acids by reduction of gaseous oxides of carbon in which a gas transfer electrode is used as the cathode.The gas transfer electrodes are preferably used as hydrophobic gas transfer electrodes. In carrying out the process it is particularly preferred to use porous, hydrophobic gas transfer electrodes made from an electrocatalyst e.g. carbon, bound in a polymer such as polyethylene or polytetrafluoroethylene (PTFE). In the case of some reactions another electro-catalyst may be added to the carbon/polymer mixture.The process is particularly suited to producing acids such as formic acid and oxalic acid.

    摘要： This invention relates to a method of producing metal electrodes by treating a metal electrode substrate so as to coat the substrate surface with a homogeneous solution of the compounds of (i) at least one metal selected from a first group of iron, cobalt, nickel and manganese (ii) at least one other metal selected from a second group of molybdenum, tungsten and vanadium, each of which compound is capable of thermal decomposition to the corresponding metal oxide. The coated substrate is then thermally decomposed and the oxide-coated substrate is cured in a reducing atmosphere at elevated temperature. Substrates coated with Ni-Mo oxides are preferred. The electrodes thus produced exhibit very low overvoltage, are of high stability with respect to their activity and can be used as cathodes for the electrolysis of water or brine.

    摘要： A mask-forming film has a transparent layer between the imageable layer and the carrier sheet, which transparent layer has a refractive index that is lower (by at least 0.04) than that of the carrier sheet or any immediately adjacent layer between it and the carrier sheet. This lower refractive index layer modifies the path of incident radiation during mask image transfer so as to provide steeper shoulder angles in the relief image solid areas. This mask film is used to form a relief image such as in a flexographic printing plate.

    摘要： Hyperclusters are a cluster of clusters. Each cluster has associated with it one or more resource groups, and independent node failures within the clusters are handled by platform specific clustering software. The management of coordinated failovers across dependent or independent resources running on heterogeneous platforms is contemplated. A hypercluster manager running on all of the nodes in a cluster communicates with platform specific clustering software regarding any failure conditions, and utilizing a rule-based decision making system, determines actions to take on the node. A plug-in extends exit points definable in non-hypercluster clustering technologies. The failure notification is passed to other affected resource groups in the hypercluster.
