inches high, mounted on an iron frame. Rectifying elements are mounted on the front of the panel, and a rheostat for each section to permit adjustment for variations in line voltage, and a voltmeter for checking both sections, are provided.
NEW RECTIFIER
• A rectifier designed for use in motion picture projection has been brought out by the Baldor Electric Company of St. Louis. Principal features of the design are described as follows :
The transformer is made of laminated electrical sheet steel, the laminations tightly compressed to reduce vibration. Windings are of single cotton enamel magnet wire, insulated from the core and saturated with insulating varnish. The case is constructed of heavy gauge sheet steel and is mounted on short legs. Louvers in the sides and top provide ventilation. The case is finished in green lacquer.
The panel is made of sheet steel having a two-tone finish. Mounted on the panel are an "on and off" snap switch, an 0-50 d. c. ammeter (if desired), and a sevenpoint control dial, which varies the amperage at the arc between 15 and 30 amperes.

Silver Screens
T N addition to being seamless as pointed out in this section in the last issue, Da-Lite Silver Screens have a high reflective value for the medium size theatre. A more brilliant surface would limit its usefulness to the more narrow houses where the Da-Lite Beaded Screen is now supreme.
