Motion Picture Herald (May-Jun 1946)

ot disagreeable odors that cannot readily be eradicated, the use of perfumes especially prepared for such conditions is often indicated. Among products of this type available are liquid perfumes to be sprayed before and between performances ; powders that may be placed in ornamental wall holders made of porous material ; and also highly aromatic pellets, which are placed in a small receptacle that clasps on an incandescent lamp, the heat from the lamp evaporating the perfume oil in the pellet. All of these deodorants are obtainable in a wide variety of odors. Compounds to be sprinkled, sprayed or added to cleaning water are obtainable under a number of trade names and in various strengths. They are requisite to the proper cleaning of toilet rooms. Solvent for scale in urinals and water closet bowls greatly facilitate the thorough cleansing of such equipment. Paradicholorobenzene crystals or cakes are commonly placed in the basin of urinals or in nearby evaporators to minimize the disagreeable odor.

DIMMERS THESE ELECTRO-ME chanical devices for controlling stage and auditorium illumination permit fading out of any desired set of lights and fading in of others. They are necessary to the production of stage lighting effects commonly desired ; their chief application to motion picture theatres, however, is gradually to raise or lower auditorium illumination before and after performances. Dimmers are available in types and capacities varying according to purpose. Resistance types without interlocking features are suited to small circuits subject to individual control (spotlight, floodlight, etc.). Interlocking models are for multiple-circuit installations (as needed for complex stage lighting). There are also reactance (electronic) dimmers for installations like the latter. Autotransformer dimmers are adapted to simple auditorium house-lighting circuits ; they may be installed for single-switch remote control (as from the projection room), or be bankmounted in various interlocking assemblies for flexible control of a number of circuits (as for illumination of different colors or locations). Due to transformer action, dimming is smnotli regardless of lamp load. Dimming of cathode type light sources ("neon" and "slimline" fluorescent) is possible with equipment especially installed for this purpose according to the characteristics of the lighting installation (with regular dimming equipment, a flicker effect occurs just before the blackout).

DISPLAY FRAMES, POSTER POSTER FRAMES built tO desired size and in plain or moulded styles, are available in extruded aluminum, in decorative natural wood finish, and in metal-on-wood (kalamein). Extruded aluminum frames cost most (about 75% more than natural wood), but they require practically no BEHER THEATRES, MAY 4, 1946 maintenance, are not affected by normal settling of the building wall, and last indefinitely. All-wood frames are obtainable in natural grains (such as walnut and bleached mahogany), with or without a protective coat of clear lacquer ; and in common wood lacquered in desired color. Kalamein frames may be had with finish in stainless steel, chromium, aluminum, bronze and other metals, also in plastic, such as Formica. Recommended lamping is that which is concealed behind the frames, with distribution such as to prevent shadows on the poster. The most efficient type of lamp for the purpose is the lumiline {see Lamps, Incandescent for Theatre Lighting). It is preferable to place them entirely around the poster in cases 40x60 inches or larger ; otherwise, the lamps should extend along the edges of greatest dimension. Poster frames of all types are available complete with frames mounted on veneer case ready for installation in wall recess (the most desirable method) or on the surface of the wall.

EFFECT MACHINES PATTERNS AND SCCnic cf fect.s with or without animation (such as moving clouds, flames, etc.) are ingeniously obtainable with these special light projection machines, essentially stereopticons, employing various types of effect slides and gelatines. Backgrounds for stage shows, in color, can be projected and changed at pleasure, or the opening of a feature picture be framed in color or given a superimposed, changing pattern. Simple and relatively inexpensive spotlights, with color wheel attachment, are also available in models for both short and long throws.

EXPLOITATION MECHANISMS VARIOUS DEVICES are available for the presentation of scenes from a current attraction or special advertising stills or motion pictures in the vestibule or lobby of the theatre, or in stores and other locations for which suitable arrangements can be made. The simplest type provides for the automatic display of a series of stills or advertising cards. More impressive is the showing of motion pictures by means of an automatic projector mounted for the rear projection of advance trailers or other advertising films on a small screen. Such equipment may be obtained either with or without sound reproduction facilities. Posters can be quickly and conveniently made, often by persons of little or no training in poster art, with the aid of a poster projetcor, which enlarges exploitation material, such as that in press books and other accessories, on the poster sheet, in the original colors, and the image may be readily sketched or painted in. For quick and easy cutting of patterns out . of paper, compo.iition or wooden board, in makink atmospheric lobby displays, etc., electric saws are available designed for such purposes.

They should be distributed throughout the theatre in accordance with the directions of fire department officials, care being taken that any extinguisher likely to be used in the presence of electrical apparatus is safe for that purpose, and not capable of electrocuting the user.
