Abstract
The non-rotating high-intensity d-c. arc is considered in conjunction with equipment that has been developed for applying it to motion picture projection. The current and consumption ranges and the crater opening of carbons when used in this equipment are tabulated. The effect of burning the arc at various currents, arc lengths, and positions is shown graphically in relation to the light upon the projection screen. The important features of the lamp mechanisms and optical systems are discussed. The sources of power used with this new type of arc are grouped in relation to arc stability and general characteristics. The influence of external magnetic flux upon arc stability and appearance of the arc is also illustrated.
