Abstract

873,565. Electrostatic precipitation. SOC. FINANCIERE D'EXPANSION COMMERCIAL ET INDUSTRIELLE S.A. SFINDEX. Feb. 29. 1960 [March 6, 1959], No. 7111/60. Class 39(1). A field emission electrode system for ionising air or the exhaust gases of an internal combustion engine comprises a tubular electrode 1, a second electrode 2 having a pointed end 2a projecting a short way within the tube and a dome Shaped tip on the pointed end having a radius of less than 10<SP>-5</SP> cms. The short distance may be between 1/3 and 1 / 5th of the length of the tubular electrode such as “ and the radius of the dome shaped tip is preferably 10<SP>-6</SP> cm radius. The electrode 2 is a wire and may be the ionising electrode of an electrostatic precipitator. A thin Cu or Ni coating may be evaporated on to the stem of the W or Ti wire electrode 2 to prevent it from oscillating. An alpha or beta radiator of radioactive material may be evaporated on to the dome shaped tip of electrode 2, e.g. thallium 204 is a beta radiator. Either electrode may be earthed.
