Coals of increasing rank contain a mixture of solid fragments and particles which look liquid. The first ones are a fractions insoluble in boiling anthracene-oil, the others are /I fractions (soluble in anthracene-oil but insoluble in toluene). The content of fi fraction passes by a maximum as softe

β¦ Synopsis
Letters to the Editor 619 molecular-weight residues at relatively high temperatures can be regarded as a general condition for producing carbon spherules. The results obtained in the series of our works on pressure carbonization [ 1,5,6,7] imply the possibility to control the structure and texture of the resultant carbons by the interaction between these two carbonaceous products from different precursors.

The emissivity of soot particles makes an important contribution to heat transfer by radiation from industrial flames. This investigation has involved the measurement of the size distribution of aggregates of soot particles from both a soot generator and a flame. The techniques involved sampling by
calls for comment to clear away certain misunderstandings. These authors remark 'The present results indicate that vitrinifes of the same level of rank as those studied by R. L. Bond, D. Chandra and I. G. C. Dryden', which were suggested as being isotropic and remaining so during carbonization, are
