The patent number you quoted seems to relate to= electrodes for resistivity tomography in coal mines.

Nevertheless, there is some general disc= ussion in the specification on the theory of arrays of earth spikes and re= ference 2 on page 4 is to the very document I am trying to get permission= to place online. =20 73 F5VLF *********** REPLY SEPARATOR *********** On 19/04/2010 at 12:13 cricri wrote: >Hello All, >I think the paper is here : >http://www.ipo.gov.uk/p-find-publication-getPDF.pdf?PatentNo=3DGB2443246&= DocType=3DA&JournalNumber=3D6206 > >Best 73 >F1VL
