Improved Equipment for Drive-in Theaters
Present trends in drive-in theaters, particularly as applied to light sources, projectors, sound systems, power supply units and projection lenses, are contrasted with those of several years ago. Current drive-ins favor the use of 9-mm and 10-mm positive carbons in reflector-type arc lamps in combination with the new 4-in. diameter lens. Comments are offered on the impact of three-dimensional pictures on drive-ins.
