The New Electronic projection lamp Electronic Timers control production of actuating impulses. These timing units are replaceable in a matter of seconds. Solenoids actuate individual carbon feed mechanisms. Over 300 parts have been eliminated — no fast moving cams, gears or gadgets to wear out. Unit construction of entire assembly is demonstrated here. Note simplicity of design and ease of maintenance. Now Available Quick Delivery The Forest ELECTRONIC Projection Lamp is in production, available for quick delivery. This is the ONLY Electronic Carbon Arc Lamp. It is simple in design, faultless in performance. Carbon feed is controlled electronically. Individual solenoids actuate both positive and negative carbons. A constant gap is maintained, thus making possible maximum brilliance of screen image regardless of the throw. Unit construction means quick and easy maintenance. Electronic timing of actuating impulses means a steady arc without continual manual adjustment by the operator. Low-cost operation means more profit for the house. Specify the Forest ELECTRONIC for your next lamp installation.
