The Film Daily (1932)

THE Sunday, May 1, 1932 Theater EQUIPMENT Studio By M. P. BOOTH THREE-DIMENSION MOVIES DEMONSTRATED BYBELLCO. Washiiuiton Bureau of THE FILM DAILY Washington — Three dimension movies were described by Herbert E. Ives of the Bell Telephone Laboratories last week before the National Academy of Sciences, but Ives held out little hope that they would be available to the public soon. Ives said successful results depend upon such extreme accuracy of mechanical and optical parts and adjustments that commercial application appears remote. Ives told how projection of motion pictures in relief has been "experimentally realized" with a new huge projector. Pictures in relief are visible, he said, to a group of observers occupying a wide range of positions with respect to the screen, but demanding no special spectacles or other optical apparatus. "The individual pictures constituting the record of motion and relief are made up of narrow juxtaposed strip images," Ives explained, "each of which is a minute linear panorama of the scene presented to the camera. "The camera consists of a concave mirror four feet in diameter, at whose focus is a transparent screen consisting of approximately 200 minute concave grooves. The virtual images of the mirror formed in these groups are photographed by a single exposure on to a lantern slide plate. "Prints from negatives so made are then mounted on a large disc capable of slow rotation in the slide plane of a projection lantern coupled with another rapidly rotating disc with an aperture which flashes a bright beam of light through the projection system as each picture comes into position." The screen consists of 200 transparent rods, each one-quarter inch in width, having convex cylindrical surfaces in front and rear, of such curvatures that linear images on the rear surfaces are projected as parallel beams into the observing space, he said. "When the pictures are projected with each panorama strip in accurate register upon a rod," Mr. Ives declared, "a composite picture is seen on the screen. This image Equipment For Fire Safety Cincinnati — Fire fighfing equipment ot every description for use in theaters, studios, laboratories, etc., is now being offered by the Marker Manufacturing Co.. tire prevention engineers of this city. Hard-of-Hearing Device Washington — A new device which, when held in the mouth, permits hearing with bones ot the head, was shown for the first time before the National Academy ot Sciences at a meeting here last week. The device, developed by Frederick Bedell of Cornell University, changes sound into the special vibrations artificially and sends them to the inner ear by way of the bones of the head. Temperature Recorders Marketed by Foxboro Co. Foxboro, Mass. — A thermometer for recording temperatures inside the theater, and which not only tells what the temperature is but when that temperature occurred, is being put out by the Foxboro Co. of this city. With the use of these recording temperatures, which are being offered both in self-contained types for measuring room temperatures o\ atmospheric temperatures and in long-distance types for measuring temperatures at a considerable distance from the recorder, it is unnecessary to depend upon the handmade records of an attendant or operator, entailing a great saving in time, and enabling the manager, through accurate records of temperature, to maintain a most correct temperature in his theater at all times for the comfort of his patrons. Automatic Temperature Controllers for use in the manufacture of films, and recording psychroijieters and humidity controllers for use in connection with the conditioning of the air for the film laboratory, are also being offered by the company. INSTALLS COOLING SYSTEM An air cooling system, so arranged that hydro cooling can be added during the summer, has been installed in the Winthrop, 500-seat Brooklyn theater, by the Typhoon Air Conditioning Co. of New York. NEW PROCESSING CO A new film cleaning company known as the Standard Film Processing Co., under the direction of Albert Beck, formerly of the Denison Film Processing Co., has opened with headquarters at 723 Seventh Ave., New York. MOVES TO NEW QUARTERS Inglewood, Cal. — Universal Microphone Co., Ltd., formerly located at 1163 Hyde Park Boulevard, has moved into its new building at Centinela and Warren Lane. varies with direction and distance of observation, exhibiting stereoscopic relief. "Succession of such pictures at the rate of 15 to 20 a second provides motion pictures in relief. Successful results depend upon the extreme accuracy of all mechanical and optical parts and adjustments." New Curtain Carrier Developed by Bruckner An improved curtain carrier, with various features that include nonfouling, no friction, noiselessness, flexibility, ease of operation, aluminum carriers, steel construction and lignum vitae rollers, etc., has been developed and is being offered by Bruckner Mitchell, Inc., of New York, manufacturers of complete stage equipment. This new type of carrier, of which nine have already been installed in the RKO Palace, New York, are reported to be meeting with great success. Other equinment installations recently completed by the company include: Complete stage rigging in the New Capitol, Trenton, N. J.; T-Bar counterweight system, asbestos curtain and tracks in the auditorium. Hunters College, New York; T-Bar counterweight system, double asbestos curtains with motor drive, light bridges, freewheeling curtain tracks in the Roosevelt, Washington, D. C, and a new type of motor-driven shutter of special design in the Thalia theater New York. Beaded Screen Making Instana,tions in Canada Installation of Super Vocalite and Chromolite screens in Paramount de luxe houses are now being made in Canada as well as in all parts of the United States, according to an announcement made by the Beaded Screen Corp. of Roosevelt, N. Y. The most recent installation reported by the company was that of a large Super Vocalite, in the Capitol, Windsor, Ont. This theater, recently damaged by fire, was able to continue the performance the following day owing to the cooperation and record time made by the Beaded Screen Corp. in making the installation. NEW ELECTRICAL LINE Racine, Wis. — A new and improved line of faders, tone compensators, microphone coupling units, power amplifiers, head amplifiers and power supply units for use in theaters, auditoriums and other sound installations and for use in adding sound-on-film to sound-ondisc installations, as well as for replacements of existing equipment, is being offered by the Webster Electric Co. of this city. HOLMES PROJECTOR CO. PUTS OOT NEW PORTABLE Chicago — A new and improved portable projector consisting of several novel and unique features including an entirely new optical system for Illumination, plus a straight monoplane filament thousand-watt lamp and a larger reflector, has been brought out by the Holmes Projector Co. of this city. The new monoplane filament type of lamp is equipped with a prefocus base, that fits into a prefocus socket which has been provided in the lamphouse to accommodate this lamp. When the new lamp is placed in the socket no adjustments are necessary. The reflector unit is unique in itself in that it has screw adjustments for both the up and down also forward and back movements. The entire lamp and reflector units are easily accessible as the lamphouse slides completely off the lamphouse base enabling replacements to be made instantly. The bottom of the lamphouse is equipped with a hole placed directly above the fan blower to permit the blast of air from the fan blower to pass up into the lamphouse which forces the hot air generated by the lamp out through the ventilated top. A special arc lamp has been constructed by the Strong Electric Co. for use on the improved projector for permanent installation. With this arc lamp equipment it is said a throw of 135 feet from machine to screen is obtainable. The entire unit is packed in two pieces making for easy portability. It has but three plug connections to make and the entire unit is ready for operation and can be operated by anyone after a few minutes of instruction, the company declares. The sound-on-film projector is being distributed by the Ruby Camera Exchange of New York, sole distributors in the Eastern states.
