TL;DR: In this paper, the phase diagram of the anthracene-acridine system by thermal analysis revealed the compositions of terminal solid solutions amounting to 2 and 88 mole % of Anthracene respectively.
Abstract: The revision of the phase diagram of the anthracene-acridine system by thermal analysis revealed the compositions of terminal solid solutions amounting to 2 and 88 mole % of anthracene respectively, and a eutectic at 8% of anthracene and 384.4[ddot]K. Relatively stable binary single crystals of composition ranging from 0 to 45 mole % of acridine in anthracene and from 2 to 10 mole % of anthracene in acridine have been obtained by the vapour growth technique. The lattice constants of the mixed crystals have been determined.

TL;DR: In this article, the authors proposed to make the transformer's magnetising inductance relatively low to improve the performance of the transformer during transients, which enables an optimisation of the PCT transformer to be made by adjusting both the core cross-section and the air gap length to achieve the desired level of transient accuracy.
Abstract: The simplest way of improving protective-current-transformer performance during transients is to make the transformer's magnetising inductance relatively low. This method may diminish transient errors but always increases steady-state errors. If the maximum acceptable transient error is defined, the primary current that may be transformed during the transient within the error limits depends on the transformer's magnetising inductance. For certain values of the magnetising inductance, this current reaches its maximum. It enables an optimisation of the protective current transformer to be made by adjusting both the core cross-section and the airgap length to achieve the desired level of transient accuracy.
