Definitions

  • WITNESSES 1/7 44 ATTORNEY Sept. 8, 1942.
  • My invention relates to a vapor electric device and particularly to a lead-in connection for the make-alive electrodes of vapor electric valves.
  • the make-alive electrode is mounted by means of a flexible diaphragm sealed in vacuumtight relation to the container of the valve and means provided for flexing the diaphragm to shift the location of the make-alive with respect to the cathode surface.
  • Figure 1 is an elevation partially in section of a vapor electric valve showing my improved make-alive connection.
  • Fig. 2 is a detailed sectional View of an entrance bushing referring to my invention.
  • Fig. 3 is an elevation showing in detail the construction of the adjusting screws.
  • the illustrated embodiment of my invention of a vapor electric device comprises a suitable container I having a mercury cathode 2 and a cooperating anode 3 therein. If desired, the anode 3 may be protected by a suitable shield 4.
  • a make-alive electrode 5 is mounted in an opening 6 in the side of the container I which is preferably provided by welding a tubular sleeve 1 into the side of the container I, said sleeve 1 having a flange 8 adjacent the outer end thereof.
  • the flange 8 is provided with a mounting ring 9 for receiving the bushing presently to be described.
  • the entrance bushing comprises a tubular supporting member I0 to the outer end of which is secured preferably by projection welding an annular flexible diaphragm ll, preferably of a metal, such as Kovar, to which a glass seal may be readily attached.
  • a hub I2 is interposed between the supporting sleeve 10 and the diaphragm H in order to facilitate making the weld and to add a proper bearing surface on the diaphragm ll.
  • a suitable insulating bushing 13 Adjacent the inner end of the supporting sleeve l0 a suitable insulating bushing 13 is provided for spacing the lead-in conductor i l from contact with the metal sleeve I0.
  • the insulator I3 is, in turn, provided with shielding members l5 and Hi to prevent the bridging of the insulator It by material sputtered into or onto the lead-in or insulating member.
  • the shields l5 and I6 form a labyrinth disposed in two spaced-apart annular members, one being spaced from the lead-in conductor and secured to the inner end of the sleeve and the other being secured in any suitable manner to the lead-in conductor.
  • the outer end of the lead-in bushing is composed of a cap-like metallic member I? preferably welded to the lead-in conductor l4 and being joined in insulating relation to the flexible diaphragm H by means of a glass seal l8.
  • a guide sleeve I9 is secured to the exterior of the flexible diaphragm ll preferably by means of a hub in spaced relation to the lead-in conductor I l and the glass seal l8 therefor.
  • is applied to the outer end ll of the lead-in conductor [4 in any desired manner preferably by welding or brazing to the external end ll of the lead-in conductor M.
  • the flange 8 is provided with suitable grooves 22 in which endless rings 23 of suitable deformable metal are placed.
  • the mounting ring 9 is placed on a seat 24 on the flange 8 after which the diaphragm II is placed in position and pressed into firm contact with the deformable rings 23 by means of a cap 25 preferably secured to the flange 8 by means of bolts or screws 26.
  • the ring 9 not only positions the support 10 but reenforces the diaphragm against excessive distortion by the atmospheric pressure.
  • the cap 25 is provided with lugs or projections 21, in which setscrews 28 are placed which make contact with pivot blocks 29 on the guide sleeve l 9.
  • the make-alive electrode 5 can then be adjusted with respect to the oathode surface by changing the position of the setscrews 28.
  • the external end of the bushing may be closed by a suitable insulating member 30 to prevent mechanical damage by accidental contact with the protruding connection 2
  • An adjustable mounting for carrying a leadin connection for a make-alive electrode through an opening in a metal container comprising a flange about the opening, a flexible metal diaphragm mounted in vacuum-tight relation to said flange, a reenforcing ring for said diaphragm, a hub welded to said diaphragm, a tubular supporting member rigidly connected to said hub, a lead-in rod extending through said supporting member and said diaphragm, a makealive electrode mounted on said rod, a glass seal between said rod and said diaphragm, an insu- I lating bushing for holding said rod in spaced relation to said supporting member, a shield for said insulating bushing, a second hub secured to said diaphragm, a tubular guide secured to said second hub and screws contacting said guide member for adjusting the position of the makealive electrode.
  • a vapor electric device comprising a container having an opening therein, a liquid cathode in said container, a make-alive electrode having a tip portion immersed in said cathode, a
  • said rod extending through the opening in the container, a flexible metallic diaphragm sealed in vacuum-tight relation to said opening, a tubular support secured to said diaphragm, the tubular support being spaced from said rod, an insulating bushing between said support and said rod,
  • shield members for said insulating bushing, a vacuum-tight insulating seal between said diaphragm and said rod, a guide member secured to said diaphragm and adjusting means cooperating with said guide member for controlling the amount of immersion of said make-alive electrode in said cathode.
  • a lead-in bushing for adjustably passing the lead-in connection of a make-alive electrode through an opening in a container comprising a flexible diaphragm sealed to the container, a supporting member connected to said diaphragm, a lead-in rod extending through said diaphragm, a make-alive electrode mounted on said rod, an insulated bearing between said rod and said supporting member, a vacuum-tight seal between said rod and said diaphragm, a guide member secured to said diaphragm and adjusting means cooperating With said guide member.
  • a lead-in bushing for passing a make-alive lead-in through an opening in the container of an electric valve comprising a flexible diaphragm sealed to the container, a supporting member connected to said diaphragm, a lead-in rod extending through said diaphragm, a make-alive electrode carried by said rod, an insulated bearing between said rod and said supporting member, a protective shield for said rod, a Vacuumtight seal between said rod and said diaphragm, a guide member secured to said diaphragm and adjusting means cooperating with said guide member for controlling the position of the makealive electrode.
  • a lead-in bushing for the make-alive electrode of a Vapor electric device having an opening for insertion of the lead-in comprising a leadin member, a make-alive electrode supported thereby, a flange connected to the vapor electric device about the opening, a reenforcing ring seated on the flange, a flexible diaphragm mounted adjacent said reenforcing ring, means for sealing said diaphragm in vacuum-tight relation to said flange, a supporting member rigidly secured to said diaphragm, an insulating member maintaining said lead-in in spaced relation from said supporting member, a guide member rigidly secured to said diaphragm and means for adjusting the guide member to control the position of the make-alive electrode in said vapor electrode device.
