...ifclfj Strong Develops New Arc Lamp For 35mm Portable and 16mm Projector A new high intensity reflector type projection arc lamphouse and associated rectifier equipment for use with 35mm portable and semi portable projectors and 16mm projectors has been developed by the Strong Electric Corp. The 2600 lu mens of light produced for 16mm projection and 4000 lumens produced for 35mm projection is approximately four times that of a mazda light source, in both instances sufficient for showing brilliant pictures up to 18 feet in width. The snow white character of the light makes it ideal for the projection of colored films. The type 48600-1 lamp for 16mm projectors uses a 6mm x 8%" positive and a 5%mm x 6" copper coated Pearlex negative carbon to burn for an hour at 30 amperes and th<> type 48400-2 lamp for 35mm pro jectors utilizes a 6mm x 9" negative and a 7mm x 12" copper coated positive to burn one hour and twenty minutes at 40 amperes. Known as the Univarc, the lamphouse weighs only 55 pounds, and shipping weight is 70 lbs. The 40 ampere type measures 29 29/32" long x 14 3/8" high x 11 7/16" wide and the 30 ampere type measures 28 13/16" long x 14 3/8" high x 11 7/16" wide. Direct current for the 40 ampere 29-30 volt arc is supplied by a 4-tube Type 16200 rectifier which measures 13" x 20" x 21" and weighs 125 pounds and the 30 ampere 26-28 volt arc is supplied by a two-tube Type 26,000 rectifier which measures 20" high x 12" wide x 11" deep and weighs 100 pounds.

The masterpiece of the most experienced projection lamp designer. No other lamp has even remotely approached its perfection from every point of view— mechanically, electrically, optically, hydraulically or its fine air-conditioned system. Its durability and stamina have been proved. More and more fine theatres and drive-ins are re-equipping with Ashcraft Super Cinex daily due to their fine reputation for perfect screen light and service. Current range with 1 3.6 mm carbon, 125-165 amperes. CORE-LITE ... the latest and most phenomenal producer of white light at lowest possible operating cost in the family of Great Ashcraft Arc tamps. Same arc burner and arc controls as the SUPERCINEX. Same quality and built-in reliability. The lamp is optically designed to give greater white light distribution at less cost for carbons and electricity. There is none better— anywhere! 70-110 amp. CINEX 35/70 SPECIAL ... The Great of the Ashcraft Arc tamps is a modified Super Cinex. tike the Super Cinex no third element or relay lens is necessary regardless whether 35 mm or 70 mm film is being projected. Uses a 13.6 mm high intensity positive carbon at current ranges between 1 25 and 140 amperes. RECTIFIER . . . THE SPECIAL CORELITE 1 2 PHASE HIGH REACTANCE RECTIFIER . . . designed for the requirements of the Core-Lite lamp, this rectifier will give the best results. Low reactance 6 phase rectifiers should not be used. Certain motor generators, but not all, are acceptable. The special Core-Lite S/1212 rectifier will give you long, excellent service with an absolute minimum of expense. Other Ashcraft rectifiers available for every power need. The cost is no more than for inferior rectifiers. SOlD *"«»WHE«E IN THE UNITED STATES BT LEADING AUTHORIZED THEATRE SUPPLY DEALERS C.S. ASHCRAFT MFG.
