  • Patent number: 4422616
    Abstract: A support arm for fastening to a wall features four longitudinally extending grooves displaced at 90.degree. intervals around its periphery and a central bolt for fixing the support arm by one end face to a wall.

  • Patent number: 4394227
    Abstract: An electrochemical process for the preparation of benzanthrones and planar, polycyclic aromatic oxygen-containing compounds is described. The process is carried out in an acid medium in an electrolytic cell which is separated by a diaphragm into a cathode compartment and an anode compartment.In the cathode compartment, anthraquinone or an anthraquinone derivative is reduced electrolytically to oxanthrone and the latter is reacted with glycerol to give the corresponding benzanthrone.In the anode compartment, a transition metal ion is simultaneously converted electrolytically from a lower oxidation stage into the next higher oxidation stage. The metal ion of higher valency is then used in the anolyte as an oxidizing agent by means of which the corresponding oxygen-containing compounds are obtained, starting from planar, polycyclic aromatic compounds.

  • Patent number: 4311565
    Abstract: An electrochemical process for the production of benzanthrone by reaction of anthraquinone as, starting material, with glycerol, which process comprises reducing anthraquinone, which may additionally contain electronegative substituents, at the cathode in an electrolytic cell in acid medium, and simultaneously cyclizing the reduced semiquinone form with glycerol to produce the corresponding benzanthrone. The novel process affords numerous advantages compared with chemical reduction methods.
