RHEOSTATS THESE ARE deviccs that introduce an electrical resistance into any circuit, the value of the resistance being variable at will. There are several methods oi varying resistance, one being to move a contact lever over a series of switch points, one being to move a slider over the coil of the resistance wire itself, and one being to compress carbon or graphite discs or powder.

Although no standards have yet been fixed, it is authoritatively regarded that the width of the image should be not greater than the distance between the first row and the screen, nor less than about one-sixth the distance between the last row and the screen. Technically, screens are of three general types : Diffusive, for auditoriums having a ratio between width and depth of approximately or more, to 5; Semi-Diffusive, for auditoriums tending toward the narrow; and Specular, for auditoriums definitely elongated. Another type is Translucent, used with rear projection. In surface treatment (which is more or less associated with the critical materials used in general fabrication) screens are "white," "silver" (metallic) or "beaded" (glass.) Specular screens are either "silver" or "beaded." A special type of curvilinear screen, constructed with characteristics of curvature according to the visual angles of an auditorium, is also obtainable.

SIGNS (ELECTRIC) FOR THEATRE NAME ELECTRIC SIGNS (metal framework with illumination provisions) are available in a wide variety of designs more or less closely associated with the architecture of the theatre front. While they are commonly especially designed by the architect or sign construction company, there are also stock designs adaptable to the theatre front Gas tube (neon) and incandescent lamp illumination have been found effective for these signs in combination as well as alone, and either type of lighting can be flashed. Horizontal name signs have normally been more closely associated with the marquee than the vertical sign has, but often the vertical sign can be eflFectively related to the marquee and entrance by continuing the sign illumination scheme down to the marquee and even across its sofiit.
