Abstract
The application of the copper-oxide rectifier as a d-c. power supply for projection is by no means new. A fan-cooled type of copper-oxide rectifier was developed by the General Electric Co. in 1930, and applied successfully to the low-intensity type of lamp as well as the Hi-lo lamp.<sup>1</sup> With the advent of the Suprex type of arc an entirely new field has been opened up. The characteristics of the copper-oxide rectifier have been found to be admirably well adapted to the special voltage and current requirements of the Suprex arc and in this service it is rapidly supplanting other types of equipment.
