    Abstract: A device applies a coating to a surface of an turbomachine annular casing, wherein the casing has an abradable layer obtained by polymerising a resin. The device includes first support means and, optionally, second automated means movable relative to the first support means. The automated means includes means for depositing said resin on the surface of the casing. The automated means further includes means for spreading the resin on the surface of the casing, and means for unwinding a plastic film that is intended to be interposed between said spreading means and the resin.

  • Process for the preparation of citral
    Patent number: 5177265
    Abstract: An improved method for preparing citral in liquid phase from prenol and prenal, wherein, in a single reaction enclosure, the prenol and prenal are condensed in the presence of a mineral acid at a concentration of about 5.10.sup.-3 mole for one mole of prenal, 90 to 95% of the acid is neutralized, and once excess prenal and prenol is eliminated, the citral is distilled.
