The Bioscope (Jul-Sep 1931)

THE BIOSCOPE MODERN CINEMA TECHNIQUE August 26, 1931 viii NEGATIVE (Contin ued from CARBONS page vii) tolerance) the conditions of running laid down for the product in question. For example, the normal current for a mirror arc using 12 millimetre positive and 8 millimetre negative is to the order of 20 to 25 amperes. A current of double this value will naturally cause the shell of the negative to burn away more rapidly than was intended, with the result that the arc will become unsteady or, in extreme cases, uncontrollable. ► Fig. 5 This is illustrated clearly in Fig. 5, which shows two brands of 8 millimetre lowintensity negative carbons, which, for comparative purposes, were each run up to the same overload. You will notice in both cases that “ spindling ” has set in, although this is very much more pronounced in one of the examples. This demonstrates very clearly the necessity not only for exercising due care in the choice of the carbons employed in your lamp, but also for using those carbons in accordance with the rating for which they were designed. These remarks, however, belong rightly to the operation and characteristics of the lowintensity arc, which forms the subject of our next chat.
