Motion Picture Herald (Sep-Oct 1936)

display cases and decorative plaques often are made of modern, ornamental bronze. Brass rails are used for control of traffic in separating sections of the lobby and foyer, for protection at the edge of the balcony, for hand rails on stairways, and to set off the orchestra pit.

CARBONS, PROJECTION motion picture projection carbons are required for projection in most motion picture theatres (all except those using Mazda light sources). The type and size of carbons required depends upon the type of arc, and in this connection the reader is referred to the several articles in The Equipment Index on projection lamps. The newer development of a positive carbon of different core composition than previous types, smaller in diameter, and non-rotating, has resulted in the attainment of a much whiter projection light at low and medium amperages than is obtainable from low-intensity and hi-low arcs. This carbon, used with a negative carbon of adapted type, is the source of the socalled "suprex" arc. A report of the Projection Practice Committee of the Society of Motion Picture Engineers, has stated : "A comparison of the Suprex carbon arc with the high-low arc at a current of from 50 to 60 amperes, showed that the Suprex carbon arc provides a light of equal intensity, but with a more even field, and of course at a much lower operating cost." This carbon is used with a special lamp and certain rectification facilities developed for it. A still later development in projection carbons (in the United States) is a superhigh-intensity carbon for use in very large theatres where the size of screen demands utmost illumination for the best presentation of the picture. It has an effective current capacity of 180 amperes. Bond Electric Corporation, Lancaster, O. Display Stage Lighting Company, 442 W. 45th Street, New York City.

CARBON SAVERS THESE DEVICES, which permit use of carbons down to a very short stub, consist in a metal rod that is clamped into the carbon jaws of the lamp house, one end of the rod being provided with means for holding a stub of carbon that is too short for use in the normal way. There are several methods of attaching the stub to the carbon saver, some of them permitting use of the carbon down to one inch. Best Devices Company, 200 Film Bldg., Cleveland, O.

Appearance, which should be in harmony with the general decorative scheme. 2. Durability. It has been found that because of the extreme wear to which theatre carpets are subjected, no economy is effected by buying the cheaper grades. 3. Acoustic considerations — installation of carpet (or of heavier carpet) may aid in overcoming certain acoustical defects in an auditorium. The standard weaves, in order of cost, from the most to the least expensive are Chenille, Saxony, American Oriental, Winton, A xminster, Velvet and Tapestry. Padding under the carpet provides a softer and more comfortable footing; increases carpet life very materially by reducing friction and keeping the carpet out of direct contact with the floor; and im W, IH WOLVERINE...

CHAIRS, THEATRE chairs and general seating arrangements are chosen to provide the optimum compromise between six requirements: maximum seating, maximum comfort, facility of entrance and exit, proper sight lines, local building regulations, and acoustics. Upon the last point, the ideal chair is one that has precisely the same sound absorption as the human body; in a theatre thus seated it is never necessary to change sound volume with changing audience conditions, and sound quality is always equal to that obtained with a full house. Veneer chairs should never be used. The importance of well designed chairs to the comfort of the theatre patron — and all possible comfort must be provided — advises careful selection of chairs in the first place, expertly supervised installation, constant maintenance and periodical reseating. Much scientific research with respect to posture and materials has gone into the designing and production of modern theatre chairs, and a similar, painstaking attitude toward seating is indicated on the part of the theatre owner. Chairs may be procured with full spring construction, or spring-edge seats, and with padded backs. Row end standards may be obtained in special designs to suit a particular decorative scheme. Coverings, of course, are always selected according to the interior treatment of the auditorium {see also articles in The Equipment Index on Chair Covers, Chair Refinishina Materials and Upholstering Materials) .
