Happy 4th of July
The Management would wish to convey to you and your family a most happy Fourth of July!
For those Exhibitors who want to feature a sing-a-long with their show....
DEVELOP HIGH-INTENSITY ARC SLIDE PROJECTOR
Projecting pictures of a size and brilliancy comparable to large-screen theatre projection, a universal high-intensity arc slide projector which accommodates 2x2-inch, 3 1/4-inch and 4x5 slides has just been developed by Strong Electric Corp. of Toledo.
This new projector fills a long-standing demand for an arc slide projector capable of projection pictures to the mammoth size screens of drive-in theatres. It is also ideal for school, college and and church auditoriums and classrooms, particularly where there is difficulty in darkening the room.
In projecting 4x5-inch slides it will largely be employed by TV and motion picture studios for projecting background scenes before which the play is enacted. A 50 C.F.M. capacity blower cools the slides so effectively that even dense slides may be projected for an hour or more without damage, it is claimed.
As compared to the yellow light of the Mazda, heretofore relied upon for slide projection, this high-intensity arc projects a snow-white light that gives the picture real brilliancy and sparkle. The projector is extremely simple to operate. It can be plugged into any 110-volt A.C. convenience outlet.
Economical of carbons, the motor-driven arc burns 6mmx7-inch copper-coated carbons at 45 amperes and 21 volts to project 7,500 lumens of light. The burning time for one carbon trim is 80 minutes. The optical system includes three lenses and a 3 1/4-inch focus polished glass reflector of 24-inch working distance and 10 1/4-inch diameter.
The length of the projector is 78 inches and adjustable legs permit establishment of the optical center at a height of from 36 to 55 inches. A projection angle of as much as 27 degrees downward of 10 degrees upward is afforded.
