Professional Skills, Modern Equipment Make Walter Reade Theatre's Screen Lighting Tops In the projection room of the new Walter Reade Community Theatre. Cherry Hill. N. J., there is a combination of professional skills and modern screen lighting equipment which is unique. Our cover photo starts a very interesting story. Frank Hauss, business manager of Local 418, Camden. N. J., and his son, Allen, are the projectionists in this newest of Walter Reade Theatres. Father-and-son projectionists on the same job is not a new situation, but when Ashcraft Core-Lite arc lamps are added, the result is a combination of professional skills and modern equipment. Projection conditions at the Community are not ideal. The picture is large and the projection distance is short and when such conditions exist, problems develop. Very short focal length lens must be used with all their attendant faults. Screen lighting and other projection problems at the Community were overcome through the use of new Ashcraft Core-Lite arc lamps. 214" E. F. Kollmorgen SuperSnaplite F:1.7 X lenses are used on the flat or wide screen picture and • >1i" Kollmorgen Super-Snaplite F:1.9 lenses are used as backup lenses for CinemaScope. The secret of the light-making capabilities of the Core-Lite arc lamp is in optical projection distances. 6-5/8" to 6-13/16" is the prescribed distance from the positive carbon crater to the rear surface of the reflector (depending upon the 10 focal length of projection lenses.) 29-1/2" is the prescribed distance from the rear surface of the reflector to the aperture plate. A 16" diameter reflector is used because a reflector of larger diameter is neither needed nor optically necessary at these operating distances which are exclusive with Ashcraft Core-Lite arc lamps. "We are proud of the new Ashcraft Core-Lite arc lamps." said Frank. "'They are fine new modern tools in the hands of the projectionist in his never-ending effort to put a better picture on the screen for the added entertainment of the theatre patron and satisfaction of the owners." Frank further commented: "These new arc lamps, with our new Simplex XL projectors and Simplex XL alltransistor sound system form a fine combination of everything that is needed to deliver the absolute best in sight and sound entertainment to our patrons free from all interfering mechanical and audio faults." The complete equipment installation was made by the Philadelphia office of National Theatre Supply Co. under the supervision of Bill Hutchins. manager, and Mickey Lewis, installation engineer. Frank and Allen Hauss assisted in the installation. Frank states that a Cinemascope picture, 40 feet wide is projected with a back-up lens of only 3% in. and a flat picture of 30 feet wide needs only a 2*/> in. lens. He compliments the Walter Reade Circuit for equipping this theatre with most modern light producing systems which enable patrons to see pictures as perfectly as they are photographed in Hollywood studios. In case there are readers who are not yet familiar with a few of the outstanding features of the Ashcraft Core-Lite, we herewith briefly outline some. The Core-Lite is a 35mm projection lamp into which is incorporated an entirely new optical system that can be integrated with the projection lenses now being used. Because the particular shape of the Core-Lite conical light beam eliminates the losses in your lenses due to vignetting, the light on the sides of the screen is increased to any degree desired. It is also designed to use only one size positive carbon, the 11mm x 17% inch high intensity carbon combined with the 5/16 x 9 inch negative projection carbon which is operated at recommended current range of 72 to 95 amperes. Because of these and other important features it burns the carbon slower and eliminates projection losses. It also reduces the carbon consumption and use of high speed lenses. Besides the present National Projector Carbon other firms will soon make available suitable carbons for CoreLite. Both Ashcraft mirrors and rectifiers are recommended for use with any Core-Lite projection arc lamp system. iP International Projectionist November. 1963
