INRICHTING VOOR HET REGELEN VAN DE GEMIDDELDE WAARDE VAN DE SPANNING BIJ EEN ELEKTROLYTISCH KLEURPROCES VAN GEANODISEERD ALUMINIUM. |
| 摘要 |
<p>The present invention provides a system for autocontrolling and regulating the average value of the voltage applied to processes for the electrolytic colouring of anodized aluminium, essentially characterized in that the wavy and symmetrical alternating current is fed from a power transformer, one of whose phases is directly connected to the charge, while the other phase is connected to the charge through two anti-parallel thyristors.</p> |
