Definitions

  • Fig. 1 shows a discharge tube comprising a tightening member according to the invention
  • Figs. 4, 5, 6, 7 and 8 show the manufacture of several tightening members embodying the present invention.
  • a tightening device for filaments of an electrical apparatus comprising a support, a securing element being provided with a linking member fixedly secured to said support thus forming a unitary structural piece, a resilient member having one end secured to said securing element and the other end operatively connected to said filament thus tensioning the latter, and a part of said resilient member intermediate of the ends thereof being spirally wound about said support, and a stay pole, means connecting said securing element to said stay pole.
