Definitions

  • the best cure is, of course, to ensure a selenium layer of uniform thickness and free from impurities on all plates manufactured.
  • the object of the present invention is to provide a palliative which will largely prevent short circuits occurring even when the conditions which normally produce them are present.
  • thermo-setting resin such as a v phenol formaldehyde
  • a thermo-setting resin such as a v phenol formaldehyde
  • the proportion is not critical, but 13% gives the best' results.
  • I is the base plate of nickelplated mild steel, with roughened surface on which a layer of selenium 2 is formed in intimate contact therewith.
  • a counter-electrode layer l of a known alloy is prayezd or otherwise deposited on the selenium ayer
  • the selenium before being deposited on the base plate I in powder form is mixed with 13% of a thermo-setting resin such as phenol formaldehyde.
  • the remainder of the resin will be distributed in grains throughout the selenium as indicated.
  • a selenium cell of the type wherein a layer of selenium is provided upon a metallic base element the improvement that comprises including in the selenium layer a powdered thermosetting synthetic resin distributed throughout the selenium layer.
  • thermo-setting synthetic resin is of the phenol-formaldehyde type.
  • thermo-setting synthetic resin is present in an amount of one to three weight percent, based on the selenium.
  • thermo-setting synthetic resin is of the phenol-formaldehyde type and is present in an amount of one to three weight percent, based on the selenium.
