MANAGERS AND PROJECTIONISTS 557 THE WOTTON VERTICAL REXOLUX.— This machine is made by the Electric Products Company, Cleveland, Ohio. It was the first vertical type (armature standing on end) motor generator set used for motion picture projection work. The Rexolux receives A. C. at line voltage, and delivers D. C. to the arc, at arc voltage, without resistance in series and the loss incident thereto. The machine is built in three sizes, viz. : One designed to operate a single lamp ; one to operate two lamps alternately, and one to operate two lamps continuously. Where two lamps are operated continuously, only the 70 ampere machine is available. The 50 ampere machine, of either MA, or twin type (the meaning of these different types will be explained later o n) occupies a floor space 17 by 20 inches, and has a vertical height of ^4 inches, to the top of cap 14, P. 1. The switchboard, supported by angle irons, is immediately over the machine, so that the entire space required for the 50 ampere equipment is 17 by 20 inches on the floor, by 5 feet in vertical height.
