STRONG LAMP
from page 10
transformer for reducing the high line voltage to a potential correct for operating the arc. an overload circuit breaker, line relay which is connected to a lamphouse automatic door switch and the necessary sockets, switches, voltmeter and terminals, all of which are housed in a substantial metal case whicb is provided with handles for easy portability. The a-c load, or rectifier input, does not exceed the 15ampere iimit provided by any 110volt convenience outlet.
The live parts of the lamp are effectively insulated from the grounded line current by use of a separate primary and secondary winding in the transformer. There is also a smoothing reactor which is connected in the direct current circuit to the arc. This reduces the a-c componen' so as to eliminate light flicker.
The lamphouse is provided with horizontal, vertical and focus adjustments for the reflector; manual controls for carbon alignment: an adjustable-speed motor for feeding the carbons; an arc imager; and an ammeter for reading the current a., the arc.
The reflector is 10V4 inches in diameter and has a working distance of 24 inches for 35mm projection and 18 inches for 16mm projection. The geometric focus is S1/^" for the 40 ampere and 4" for the 30 ampere to result in an f value of f 2.3 on the 40 ampere and f 1.6 on the 30 ampere to match the commonly used lenses of modern projectors.
