Exhibitors Herald and Moving Picture World (Apr-Jun 1930)

April 12, 1930 Exhibitors Herald-World 109 Stereopticons CTEREOPTICONS are used for the ^ projection of lantern slides and effects, illumination being supplied by incandescent or arc lamps. They are made in single units and also for double and triple dissolving. Many unusual effects are possible with the modern stereopticon as developed for theatre use. They can be obtained for as low as $26.00 for Mazda type. BEST DEVICES COMPANY, Film Building, Cleveland, O.

Sweeping Compound 'T'HERE are a number of these on the market, many of which are very efficient. They are made from a composition impregnated with oil so that in sweeping the theatre very little dust is raised. These compounds also have in them disinfecting material which disinfects the floor as it is swept. They come in 75-lb. drums, 100-lb., 200-lb. and 300-lb. barrels. Prices range at about $2.50 per 100 lbs. The Huntington Laboratories, Inc., Huntington, Ind. Switchboards /CONTROL of lighting through the use ^ of switchboards makes possible the wonderful lighting effects achieved in motion picture theatres today. Switchboards for this work are built in many capacities. Scenes for unusual lighting effects may be pre-selected by such a board and the theatre flooded with appropriate lighting scheme at a proper cue, by the simple method of throwing a switch. Lighting control systems are being adopted by theatres of lesser size that heretofore have considered such installations as being only for the larger metropolitan houses. Manufacturers of this type of equipment are glad to furnish engineering service and consult with exhibitors and architects on various phases of these lighting control systems. A new device for automatic and preset control of stage and house lighting has recently been developed. The principle is very similar to that employed in the playing of pipe organ music and may be operated manually or automatically from the player roll. Novel and spectacular effects are thus produced with the possibility of synchronization with the program. FRANK ADAM ELECTRIC COMPANY, 3650 Windsor Avenue, St. Louis, Mo.

BORDERS FOOTS COVES FLOODS BEAM-2FLOODS SPOTS OLIVETTES YOU CAN GET BEL-CROME ONLY IN Only in Bel-Sun-Lite can you get Bel-Crome, the alloy of chromium that is the most efficient reflect' mg material ,as well as being tougher, lighter and stronger. It is tarnish-proof, too hard to scratch, and reduces the weight of lights so much that more economical rigging and easier handling result. Bel-Crome is now used in all Bel-Sun-Lites, though the older styles are still carried for those who desire them. In securing Bel-Crome for Bel-SunLite users the unvarying Belson policy of always being first to introduce the latest proven improvement is again evident. Bel-Crome has been exhaustively tested by both lighting engineers and stage illumination experts. Therefore we urge your investigation of Bel-Crome before deciding upon new equipment. Our representative, whose name is in the classified phone book of the nearest listed city, will gladly give you all information. Belson Manufacturing Go. 802 Sibley Street Chicago, 111. Atlanta, Ga.

From projection room to stage and to manager’s office, electricity to a large extent runs the show. With the program on a minute schedule, electrical switches in turn have an important duty to perform. FRANK ADAM ELECTRIC COMPANY, 3650 Windsor Avenue, St. Louis, Mo.

Telephones, Inter-Communicating Refer to INTER-COMMUNICATING TELEPHONES Temperature Control Apparatus rT'EMPERATURE control apparatus A are devices for automatically controlling the temperature of the auditorium, organ chambers or any part of the theatre where a uniform heat must be maintained. In a control for an auditorium the device is a small thermostat, which actuates a valve on an air-line, which in turn operates the shutters in the air ducts. In the average size theatre several of these will be located at various places and each will operate independently of the other, thus relieving hot or cold spots in any one section. Controls for organ chambers turn on or off electric heaters and also work on the thermostatic principle. The Electric Heat Control Company, 5902 Carnegie Avenue, Cleveland, O.

Terra Cotta, Architectural nPHEATRE architecture and decoration A today reflects both the freedom of individual expression and the character of the showplace itself. Not least in the material forms of that expression is terra cotta, with the variety of structural decoration it affords. Midland Terra Cotta Company, 105 W. Monroe Street, Chicago, 111.
