Definitions

  • the double cut shown by the dotted line will isolate none of the illustrated electrodes even if it is powered through one only of the two ends; there are however some positions where a double cut would then isolate some part of the electrode, but this can be avoided by employing more clips. It may be noted that the number of clips that achieves this preferred level of protection is five as illustrated, ie. equal to the number of loops 8a.
  • the surface area of the recess is preferably at least 25 mm2 more preferably at least 50 mm2, more preferably at least 100 mm2, particularly at least 200 mm2, especially at least 300 mm2.
  • the value chosen will depend on the tendency of the materials in question to react and on their resistivity.
  • the member 15 provides electrical interconnection and some mechanical interconnection.
  • the blocks 16 serve merely to locate the member 15 with respect to the electrode portions. If member 15 is a metal, it should preferably be a passivating metal such as titanium, tantalum, or niobium.
  • Figure 11 shows an additional securing means 17 which may retain or help to retain the electrode portions in the recesses 9.
  • the recesses need not of course be reentrant (ie. have a neck) in cross-section to stop the electrode portions falling out.
  • Figure 11 also shows means such as a pin extending from the base of the clip or a screw or bolt that extends through the clip, by means of which the clip maybe secured to some other article, for example a layer of concrete. Any of the clips illustrated may be provided with such a connecting means.
