Abstract

1473622 Electric resistance heating BODEN SEEWERK PERKIN-ELMER & CO GmbH 21 March 1975 [22 March 1974] 11964/75 Heading H5H [Also in Division G2] The electrodes 16, 18 of a resistance heated graphite tube 10 in an apparatus for generating an atomized sample for spectrography, are in contact with a conductive cooling jacket members 28, 30 on a cylindrical surface and the respective materials are of such co-efficients of thermal expansion that the contact pressure between the cooling jacket members and the electrodes is increased when the apparatus heats up.
