Title: A process for the reactivation of active carbon which has been used for the removal of carbon disulphide from exhaust air
IPC: C01B31/08
Filed: 1957-10-25
Abstract: Active carbon which has been used in the removal of carbon disulphide from air, e.g. from a viscose process, and has become fouled with sulphur, e.g. 20% of sulphur, is reactivated by extraction of the sulphur with carbon disulphide and removal of the carbon disulphide from the treated carbon.  The carbon may be regenerated in the carbon disulphide absorption chamber or in a separate chamber to which the carbon may be transferred after removal of fines.  The fouled carbon may be cooled, e.g. to a temperature of 35 DEG C., by flushing with cold air and the cooled carbon may be flushed with an inert gas before extraction. Carbon disulphide may be removed from the fouled carbon by flushing with steam, the steam treated carbon being subjected in succession to drying, e.g. by flushing with hot air, cooling, e.g. by flushing with cold air, and optionally flushing with inert gas before extraction.  Sulphuric acid may be removed from the fouled carbon before extraction by washing with water, the washed carbon being dried, e.g. by flushing with hot air followed by cold air, and optionally flushed with an inert gas before extraction.  In the extraction step two thirds of the fouled carbon may be covered by the liquid carbon disulphide for a period of 0.5-2 hours.  After draining off the carbon disulphide, residual carbon disulphide may be removed in known manner by means of steam.

In making roll-type capacitors, the roll is strengthened by a rigid core during the moulding of an insulating case around it, the core being then removed and impregnant forced into the dielectric through the central hole. A rigid wire, rod or tube B of metal or plastic is inserted into the mandrel hole of roll capacitor A or the mandrel may be retained and the flanges of flanged hollow metal eyelets C which are pushed over the ends are soldered or welded to the electrodes. The assembly is then placed in a mould supported by the protruding ends of rod B and a casing E of e.g. thermosetting plastic moulded around it. Alternatively, an eyelet C is used only at one end, the other electrode connection being via a spiral or wire soldered to the electrode, or else ordinary terminals off the axis may be used at both ends. After the moulding the rod &c. B is removed, bushes being inserted between case and rod in the latter case, if the case and rod are adherent, to facilitate removal. After drying by treating in vacuo the dielectric is impregnated with hydrocarbon oil, jelly, or wax, through the central hole, which is then sealed by soldering a wire into the eyelet.

Abstract: Epoxyalkyl esters of monocarboxylic acids are made by heating an epoxy halogen alkane with a salt of the carboxylic acid which is in the form of a suspension in an organic solvent, said suspension being made by adding an aqueous solution of a hydroxide to a solution of the acid in an organic solvent and distilling off the water. Suitable solvents are hydrocarbons, halogenated hydrocarbons and ethers. It is preferred to use a solvent which forms an azeotrope with water.  Specified hydroxides are alkali hydroxides and quaternary ammonium hydroxides.  Tertiary amines or quaternary ammonium salts may be used as catalysts.
