NEW EQUIPMENT Contirtued from preceding page invented by Buford Grigg, operator of the Sunset Drive-In Theatre, Gastonia, N.C. It has been displayed at recent conventions, including the Theatre Owners of America in Miami. Grigg has been working toward development of the unit since 1949 and now holds a patent and pending patents for its manufacture. Sounair uses a specially designed, eight-inch, dual-coned speaker with ranges from 50 to 1,800 dbs; 3.16-oz. Alnico V magnet, V.C. impedance 3.2 ohms; V.C. diameter, three-fourths inch; air gap surfaces cadmium plated with moistureresistant and fungicidal treatment. Each unit serves two cars, and is fully equipped with safety thermostats. In summer, the condensing unit using a Tecumseh compressor slides into the regular unit which provides sound and heat. All-Transistor Optical-Sound Amplifier System A new, all-transistor, optical-sound amplifier system is available from Eprad, Inc. Conceived and designed in Eprad’s sound and engineering laboratories, the amplifier system is the culmination of two years of research and development efforts to provide the theatre industry with a quality and highly reliable amplifier system at a low price. Key features include alltransistor design and plug-in construction. The system is self-contained in one cabinet and is complete with pre-amps, power amplifiers and power supply. A standby amplifier, optional at extra cost, fits into the same cabinet. The optical-soimd amplifier system is compatible with all soundheads including photocell, photodiode, photo-transistor and magnetic. Four inputs, film, phono, mike, tape or radio can be selected by means of a selector switch. New Liquid Solvent to Eliminate Urinal Odors Urinal odors in theatre restrooms are difficult to combat because 90 per cent of the odors are caused by urine salts that cake in the pipes below floor level. In order to eliminate this problem, a pint of “Gone,” which may be obtained from Regan Supply Co., Inc., is poured into the urinal at night and allowed to stand overnight. Gone acts as a urine solvent and odor suppressant, since it eliminates the cause of odor, removing the urine scales. Since Gtone does not mix with water, but floats on top and does not become diluted, it works at full strength. Application is once every two to three weeks. Gone, according to Regan, is harmless to plumbing, contains no acids or alkalies. BUY DIRECT FROM allantyne Save on equipment from one of the oldest equipment companies.
