  • Electrochemical hydroxylation of certain aromatic compounds
    Patent number: 4096052
    Abstract: This invention provides a process for the electrochemical hydroxylation of aromatic compounds ring-substituted with an electron-withdrawing moiety and having a replaceable nuclear hydrogen. An aqueous liquid comprising the aromatic substrate and the anion of a strong carboxylic acid provided by a strong carboxylic acid or the salt of a strong carboxylic acid is electrolyzed to produce a nuclear-substituted hydroxy derivative of the aromatic substrate wherein the hydroxy group replaces a nuclear hydrogen.

  • Blood filter unit
    Patent number: 4038194
    Abstract: A blood filter unit comprising an assembly for supporting a filter cartridge, a filter cartridge, and a housing for the assembly and cartridge. The assembly for supporting the cartridge comprises a permeable cylindrical core with a bottom member and a top cap. The filter media, in the form of a cartridge, is disposed about the periphery of the core and extends between the bottom member and top cap. The core contacts the media only at intermittent areas spaced longitudinally and circumferentially about the core. The core, media and walls of the housing are tapered with respect to each other.
