Definitions

  • the compressible watertight ring 4 is of any cross section and is introduced in groove 3 which has a substantially rectangular cross section, these cross sections being substantially equal in order to permit the placing of the ring 4 in the groove 3 by compression.
  • the depth of groove 3 equals about 2/3 of the room necessary for ring 4 in order that the latter be driven by the crystal during its extraction by means of a tool engaging in groove 2.
  • this joint is positioned under strong pressure.
  • groove 12 can be rectangular or rounded.
  • the cross section of joint 4 is also of any shape.
