International projectionist (Jan 1963-June 1965)

Equalizing Sight and Sound (Continued from page 9) the "dim" lamp should be adjusted by trial and error to see if shortening or lengthening this distance by small increments steps up the brightness to the level obtained with the other lamp. (It may be necessary in the case of some lamps to move the entire lamphouse forward and back on the projector lamp table.) As a rule, moving the mirror closer to the mechanism distributes the light more evenly over the screen; moving it farther away increases the brightness at the center of the screen. The arc (crater) position must be readjusted each time the working distance is changed, of course; and FIG 2 — The light transmission of a 2-blade shutter depends upon the angular width of the blades, measured with a protractor. The shutters in both projectors of an installation should have blades subtending the same number of degrees. you should wait until both lamps are perfectly adjusted before setting the arc-indicator cards or arcoscope screens. Very slight brightness differences can often be eliminated by adjustment of the arc (geometric focus) in one of the lamps; but this method should not be relied upon to "iron out" gross differences because changing the arc focus changes the color of the light. iP B Er K Opens First Chicagoland House Since Late 30fs The first new Balaban & Katz theatre to be erected in the Chicago area in 27 years is due to open this fall at a site adjoining a shopping center in suburban Oak Brook, 111. Ground-breaking ceremonies last month were attended by Oak Brook Mayor, Ted A. Mehlman, David B. Wallerstein, president of Balaban & Katz, Richard M. Bennett of Loebl, Schlossman & Bennett, architects, Douglas Kramer, vice president of Draper and Kramer, Inc., agents, and Miss Helen De Witt, executive secretary of the Oak Brook merchants association. Also on hand were Norman Cohn, president, and Bernard Blake, vice president of the Inland Construction Company of Morton Grove, contractors for the project. The design and decor of the new theater will conform generally to that of the shopping center it adjoins. iP Ampex Names Robt. Hill Ad Sales Promotion Mar, Robert G.

ERROR International Projectionist is doubly regretful about its error in reporting the recent 25-30 Club dinner dance in New York. It was erroneously reported that Local 306 makes up the bulk of the club's roster; in fact, most of its members are not New York area people, but belong to locals all over the U.S., Canada, England and New Zealand. It is also regretful that more of these members couldn't attend the party, as it was reportedly one of the nicest functions yet held by the group.
