摘要： In an electrode suitable for electrolysis of aqueous sodium chloride or potassium chloride solutions, at least the outer layer contains spinels, specifically a mixture of the individual spinels of iron and of cobalt, the weight ratio of iron spinels: cobalt spinels being from 30:70 to 90:10.The electrodes are produced by applying a powder mixture of iron spinel and cobalt spinel to a substrate by a plasma spraying process wherein argon is used as the plasma gas and the spraying energy is from 6 to 30 kW.

摘要： A gas-evolving metal electrode consists of profiles which are arranged parallel to one another in a horizontal plane and are connected to one another by means of current distributors. The profile surfaces which face the counter-electrode are curved, the curvature at the sides being more pronounced than that in the middle. The profile is terminated above by means of two lateral surfaces tangential to the curvature. The electrode is useful as an anode for mercury cells for the chloralkali electrolysis.

摘要： A process is described for cleaning in each case part of a plurality of filter elements arranged in a filter chamber (1 to 6), which are used for removing the dust from a pressurized dust-laden gas using scavenging gas supplied in the opposite direction to the normal flow direction. The scavenging gas flows from the clean gas side through the filter elements from which the collected dust is to be removed. The scavenging gas is branched from the pressurized clean gas flow removed from the filter elements not subject to the cleaning process. The scavenging gas from the particular filter chamber is supplied to the dust-laden gas side. The mixing of the scavenging gas with the dust-laden gas takes place with the aid of a compressed gas jet pump (8), which also exerts a suction action on the scavenging gas.
