CMaBs reports on: 254,000 square feet, with tailor shop . . . crystal growers' Silver Nitrate · • . how Bob Sinclair passed the time on the way down For the customers' customers' customers A little party was held in Kingsport, Tenn. recently to cele brate our dedication of 254,000 square feet of laboratory space. The sober mind can find such affairs dull until, beneath the mood of innocent self-congratulation appropriate to the occasion, it sees the situation realistically. The day-to-day material life of the nation is to be consider ably affected from these 254,000 square feet, not surreptitiously but anonymously for the most part. Eastman Chemical Products, Inc. (Subsidiary of Eastman Kodak Company lo cated there) prefers to see all the credit radiate out to its cus tomers, and its customers' customers, and its customers' cus tomers' customers. Some of the chains extend out quite long. Each link draws some reasonable quota of technological support from the next one inward. An outfit like us, working the center position, is expected to generate answers on its own but steal no thunder from manufacturers of swimsuits, Mars probes, or fudge when they put a product of ours into theirs. The newly dedicated acres comprise three laboratories charged with making this aspect of present-day industrial society work properly. We don't call them research labora tories, because those are entirely separate and concern them selves more with next decade's business than this one's. These service laboratories belong right in the midst of the production hurly-burly, right where our people who manufacture the stuff will get themselves wound up in the customer's problems. That's where they have been put. "The stuff" includes polyester fibers, acetate fibers, modacrylic fibers, butyrate plastics, propionate plastics, acetate plastics, poly ethylene plastics, polypropylene plastics, polyallomer plastics, a re markable adhesive, plasticizers, textile dyes and finishes, lacquer ingredients, aircraft functionalfluids,food-grade antioxidants, rubber antiozonants, gasoline additives, paper-coating compounds, and tankcar industrial alcohols, aldehydes, acids and anhydrides, inter alia. Anybody in a position to order any of this marvelous array of materials in industrial quantities has the right to see what happens when fair questions are asked about their use. Phone 615-246-2111. Incidentally, the new setup includes a tailor shop, which makes sense, but you wouldn't want it in a research laboratory.
of perfection to be interesting. That's how come much solidstate literature continues to deal with silver chloride. The experimenter acquires the purest AgNC>3 he believes in, reacts it with HC1, melts the AgCl powder, and from the melt grows crystals many centimeters in diameter. Nowadays he usually also zone-refines. If he chooses to place his faith in our Specially Selected Silver Nitrate (EASTMAN X-491), he has our assertion that it contains less than 5 parts per Mlion of Hg and in parts per million, less than the following limits of spectrographic measurement: Cu, 0.1; Fe, 0.1; Pb, 0.3; Ni, 0.2; Sn, 0.1; Bi, 0.1; Pd, 3.0; Zn, 10.0; Cr, 0.2; Mn, 1.0; Cl~, 4.0; SO4", 6.0. The $6.20 premium he pays over the price of 500 grams of plain Silver Nitrate (EASTMAN 491) seems a modest share of the cost of the technology that supports the assertion. And we do not assert that plain EASTMAN 491 does not meet the above-quoted specification. Orders should be placed with Distillation Products Industries, East man Organic Chemicals Department, Rochester 3, Ν. Y. (Division of Eastman Kodak Company). For reprints of two of our publications on the preparation of high-purity silver halide crystals or to engage in brotherly banter on subjects like optical absorption edges and inter stitial ions, address Eastman Kodak Company Research Laboratories, Physics Division, Rochester 4, Ν. Y. This camera can also be loaded without the use of a parachute The proper thing to do to dramatize a new type of household camera is to mount a professional movie camera atop your crash helmet, jump out of an airplane from 7,000 feet with Mr. Bob Sinclair, and while in free fall with Mr. Sinclair, photo graph him for a TV commercial in the act of loading one of the new cameras.
The fraternity of purity To conform to the spirit and letter of our charter, we go through the motions here of making a pitch for business on extraordinarily pure silver nitrate at $38 for 500 grams. We know all too well we won't sell enough to pay for this advertis ing space. We also know in our hearts that we are not here squandering funds entrusted by the shareowners. Our longrange goals will be well served if a few sales of this material should open up friendly relations with solid-staters whose acquaintance we have not yet made. We have an abiding in terest in the physics of the solid state and need all the company we can get in the pursuit of that interest. More than 50 years ago, well before "solid-state" became a label for a discipline, the founder of the business was per suaded that to go on any longer than necessary treating photo graphic emulsion-making as an art form would prove folly. As a result of both long-range and short-range thinking, he created an atmosphere around the place that had the effect, years after his departure, of making the silver halide crystal one of the more readily prepared objects of study for those who feel deep curiosity about the nature of purity just short enough
After Mr. Sinclair is sure the cam era is all set for picture-taking, he snaps Miss Donna Abrescia, another former passenger in the aircraft, on the film so loaded, with the accom panying result (but in color). Then ripcords are pulled. Honest! While it remains possible and even permissible to purchasefilmin rolls, to retire with it to a place of subdued light, and there to thread the mechanism, such behavior becomes lovably quaint with the advent of the new KODAK INSTAMATIC Camera demonstrated by Mr. Sinclair. In "electric-eye" models, the mere act of dropping in afilmcartridge even automatically sets the exposure control for the speed offilmcon tained within. Only in the processing laboratory does the film finally emerge from its cartridge. INSTAMATIC Camera prices range from less than $16 upward. See nearby dealer. Prices subject to change without notice.
