Abstract

1,020,042. Arc blow-torches. HITACHI SEISAKUSHO KABUSHIKI KAISHA. March 14, 1963 [March 14, 1962], No. 10188/63. Heading H5H. [Also in Division H1] An arc source, e.g. for use as a light source for spectral analysis, comprises a hollow electrode 1 having a nozzle 2; a rod electrode 4; means for creating an arc between these electrodes ; and means, e.g. the bar magnet 6, for creating a magnetic field to fix one end of the arc to a given spot on the surface of the hollow electrode. A stream 7 of a carrier gas, e.g. argon or nitrogen, is passed through the electrode 1, and a second gas stream 8 carries a sample, in powder or spray form, into the arc. The magnet 6 fixes the arc root so that chemically active components of the sample do not come in contact with the heated electrode wall at the arc root, and also so that a constant intensity of light source is obtained. The permanent magnet 6 may be replaced by a coil, and the light output of the device may be modulated by the coil.
