LENSES, PROJECTION THERE ARE two general classes — the condenser lens, which focuses the projection light on the aperture (See Condensers) ; and the objectives. The latter are commonly referred to as the projection lenses ; they focus the light upon the screen. . They are made in four standard diameters, with focal length as determined by the size of the screen image desired, and its distance from the projector. Kiiowing these factors, the supply dealer or the lens manufacturer readily determines the focal length required. In ordering projection lenses, one should also name the type of light source, projection angle and the make and model of the projector. Stock focal lengths are usually in quarter sizes from 3 to 7 inches, 7^ and 8 inches. In addition to the regular optical glass projection lenses corrected for color and flatness of field, so called "coated" lenses are available. They differ in that the optical components have inner and outer surfaces chemically treated so as to effect a certain disintegration of surface and a resultant film or "coating" of pure silica. Focus is also sharpened by such coating. Bausch & Lomb Optical Company, 652 St. Paul Street, Rochester, N. Y. Ilex Optical Manufacturing Company, 726 Portland Avenue, Rochester, N. Y.

LENS ASSEMBLIES, SOUND OPTICAL UNITS are composed of lenses or lenses and prisms, and include either a slit opening or a wedgeshaped prism, by means of which the exciting light of the sound system is locussea on the sound track, and reduced to the height determined by the smallest frequency to be reproduced.

LETTERS AND FRAMES FOR ATTRACTION ADVERTISING FOR ADVERTISING the Current program in luminous display on a marquee or adjoining location, changeable letter equipment is available in frame design and in styles and sizes of letters and accessories that allow forceful as well as highly legible announcements. Modern practice predominantly employs lighted white backgrounds with black aluminum silhouette or translucent colored plastic letters. Frames designed to fit into marquee or comparable structures, with white translucent glass panels, variously provide for convenient servicing of the lamp box and for attachment of letters. In all, however, bars for letter attachment are spaced 7 inches and all letters (above 4-inch types) are designed to fit interchangeably. Regular sizes (though plastic letters have not yet been produced in all of them) are 8, 10, 12, 16 or 17, 24 and 30 inches. Four-inch letters are attached by means of a special interlinear frame. Plastic letters are obtainable in red, blue and green, and other colors may be had to order. Aluminum silhouette letters in color are also available. Advertising accessories include pictorial transparencies (such as star portraits) and clip-on plastic colored letters for interior signs (such as coming attraction displays). Additionally, the opal glass letters (luminous letters on black metallic backgrounds) once generally used for attraction advertising, are still available, largely on special order.

For the public areas of the interior, lighting facilities are to be divided into two general classifications — (1) built-in sources, and (2) fixtures. Built-in sources include coves and troughs, recessed light boxes (usually having a diffusing FLOOR MATTING for Promoting Safety • Providing Comfort • Reducing Fatigue I Furthering Sanitation EZY-RUG RUBBER Traps all dirt at the door, Iceeps It out of sight and provents tracking through the building, reducing cleaning costs and frequency of redecorating, necessitated by dirt whirled into the air by the heating system.

Both classes of light sources are suited to modern interior treatments; indeed, even though built-in sources be used in the auditorium, or perhaps the foyer as well, fixtures may serve the needs of the lobby, or the lounge more economically. Either method, of course, may well be used throughout the interior, for each embraces a vast array of practicable devices for efficient illumination and effective decoration. Modern fixtures are available in stock designs of great variety — bracket or pylon luminaires, flush-type ceiling drums and boxes, suspended troughs, ceiling bowls, wall urns, etc., constructed of metal or glass or both, variously ornamented in the same materials, in direct, indirect and direct-indirect types, or with light emission through decorative louvers, in sizes to suit every location, and at prices to make modern luminaires accessible to theatres of the most modest budgets. Specially designed luminaires are obtainable at relatively moderate cost. While incandescent lamps (as distinguished from the gas tube sources generally referred to as neon) are more flexibly adapted to theatre interior illumination, and also have maintenance advantages, neon has its interior applications, confined largely to cove and trough lighting.

LIGHTS, SPOT AND FLOOD SPOTLIGHTS AND floodlights are available in many sizes and light capacities, "and in both incandescent and arc types — incandescent for use on and near the stage, for display and architectural lighting ; arc sources for stage lighting from the projection room. Incandescent spot and floodlights (most spotlights are adapted to flood applications) are designed for wattages of from 75 to 2,000. Arc equipment is available in capacities of from 25 to 140 amperes. 46 BEHER THEATRES. MAY 4. 1946
