Spectroscopist Perkin-Elmer is engaged in t h e development of advanced instrumentation for ultraviolet analysis. W e have an unusual opportunity for a man with an M.S. or P h . D . degree who has specialized in ultraviolet spectroscopy. This man must have a basic knowledge of the general application of ultraviolet techniques and a strong interest in instrumentation. H e will be responsible for field liaison and the interpretation of field requirements. H e must be capable of directing application research programs on an independent basis. • Salary will be commensurate with ability. Excellent opportunities exist in other areas of instrumentation at Perkin-Elmer, including infrared and emission spectroscopy. Send your resume to Mr. H. M. Moran

impressive, b u t still expanding, list. On May 2 9 , Bob Cuber, in charge of rotary operations for Mack Printing, leaned out to take a final look toward the far e n d of t h e 70-foot maze of machinery that makes u p Mack's n e w Cottrell rotary press. Then, glancing over his shoulder, h e reached back and pressed a button. A loud klaxonlike

C&EN reaches another high point in its 35-year history. Production Manager Joseph H. Kuney, Editor Richard L.Kenyon. Editorial Director Walter J. Murphy, and Mack Printing's Robert Cuber inspect first copies off the new press warning signal pierced the clatter of flat-bed presses operating nearby. Slowly, almost ponderously, a ribbon of paper started threading its way from roll to folder. Cuber again pressed the button and the ribbon picked up

speed. Finally, several minutes and several pushes of the button later, the huge rotary reached its "cruising" speed. Seven hundred feet of paper strip were racing through the machine each minute to produce about 14,000

UNION The assembled press is about 72 feet long, 13 feet wide, and 17 feet high. Two rolls, over 2000 pounds each, are simultaneously printed under the operation of a four-man crew. Twenty rolls are needed for a 128-page issue. At the folder end the printed, cut, and folded pages are collected for stitching. Ink imprints are instantaneously dried in the press by passage over multiple gas-burning jets

CIETY the switchover to rotary means savings in those two increasingly precious commodities, money and time. O n paper alone, for example, costs will b e lowered by 2 1 / 2 cents a pound. Using paper rolls rather than sheets makes the difference—paper cutting costs come high. Until now, a 128page issue required the simultaneous use of at least eight flat-bed presses. At 50 hours per press, press run time for the issue was 400 hours or more.

Curved plates, shown being mounted, are the biggest single cost item in rotary printing. The electroplating operation was set up in Easton by a Reading firm mainly for Mack's needs

In two runs of 64 pages each, a 128page issue goes through the new rotary equipment in 14 hours. Thus, the elapsed "in press" time is cut by almost 70%. This machine, says D . W. Riddagh, Mack vice president and plant manager, is the first unit-type, short-run magazine production press to be built by The Cottrell Co. Editorial Director Walter J. Murphy, watching the startup of the new halfmillion dollar press, commented, "This is a somewhat different order of magnitude from the 12-page News Edition first published on Jan. 10, 1923. "Interestingly enough," reminisces Murphy, "the single article in the first issue was on the subject 'Research as a Basis for Credit/ A lot of research, along with a lot of credit, has been reported in the past 35 years. Of course the author, John Teeple, was talking about the relationship of research and financial credit. "Truly C&EN stands alone as 'The Newsmagazine of the Chemical World.' The first issue reached 15,000 chemists and chemical engineers—today's total is approximately 100,000. An extrapolated curve showing future growth as seen in the crystal ball indicates possible need for a second rotary press in the not-too-distant future." Mack Printing agrees. And it will b e ready. When installing new utilities for the present unit, it provided enough capacity for the day when another similar unit will be purchased. m
