Definitions

  • the sealing of the cell may be achieved in a surprisingly effective manner by providing a thin sheet of flexible material, resistant or made resistant to the cell gases, wide enough to span the width of the cell and of a convenient length to form the As the electrolytic process pros claims. (c1. 204-219) cov-er thereof, the said thin sheet having holes to t Ythe supporting rods of the anodes and being provided with sealing means adapted to prevent the escape of gas through the hole and past the anode supporting rod.
  • the supporting rods may be machinecl so that the diameter of the upper portion is less than the lower, thus forming a horizontal shoulder on the supporting rod, the joint between the supporting rods and the ilexib1e sheet being thenmade by means of a joint-ring of resilient material between the horizontal shoulder thereon and the inside surface of the flexible cover andA another similar joint-ring between the .outside surface of the flexible sheet and a metal coverdome over the upper end of the anode supporting'.
  • Electrical contact with the anode supporting rod may be made by means of a vertical copper conductor tted into the supporting rod and passing through the metal -cover-dome, the whole assembly being maintained tight by means of a nut on the copper conductor, which nut holds.
  • FIG. 1 shows a vertical section through a cell Aconstructed accordingl to the invention and Figure 2 is a vertical section showing in detail a suitable means of sealing the anode supporting rods to the flexible cell cover.
  • Figure 3 shows a vertical section through a pre-- ierred means of sealing the supporting rod to the cell cover.
  • the flexible cover I is is tightly secured to the ilange of the lower part of the cell by means of a metal strip 2, which strip is held in position by bolts 3, 3.
  • the anode 4 of the cell has an undersurface substantially parallel to cell base plate 2
  • This method of supporting the anode is more fully described in copending application No. 20,564 of G. T. Meiklejohn, now U. S. Patent No. 2,596,583.
  • the upper ends of the anode supporting rods 1, 'l are so machined that they are provided with a horizontal shoulder 8, between which shoulder and the exible cover I there is located a joint-ring 9 made of soft rub- -ber neoprene or other resilient material.
  • Witlfr'regard. to the celll cover which may beef any suitable flexibler and resistant' material; it'V isi to, ⁇ benoted that" this may be constructed from several! nexi-ble' sheets, suitably jointedftogethertomaintain the gas-tightness of the cell?, polymerised methyl methacrylatebeing particularly'. sui-table'k for building uptheI celll coverl this way', ⁇ since the individual sheets maybe cemented ⁇ together at: their' edges b'y mea-nsof'fcement vcomprising the: monomer containing' the polymer solution.
  • a ilovving;.mercuryv cathode electrolytic cell havingfcontinuous andi-automatici adustment of the height of the anode comprising in combination a substantially horizontal cell base plate for supporting a owing mercury cathode, side walls, an; anodehaving'anl undersurface substantially parallelto said.
