What's more, if youneed it (even while employed by your currentemployer), you can withdraw all the money you haveaccumulated by surrendering your contracts. Or, youcan withdraw $1,000 or more every six months. Thereis never a cash surrender charge.

Contributions are tax-deferred,so you pay less income taxes now.

The federal income tax on your contributions isdeferred until they are paid to you as benefits. So, youpay less tax now.

Changing employers? Take SRAs with you.Since you own your Supplemental Retirement Annui-ties, you take them with you if you' leave your currentemployer. You can make contributions through anyinstitution that makes Supplemental RetirementAnnuities available to staff members. Contributionscan be as little as $25 a month.

Some chemical engineersrarely get towear hard hats.

Film differs from Rembrandt's better film can be widely afforded.medium. Most who expressthemselves with it do not know orcare how it is made. Before 1880,no one knew how to make it.Today, no one is remotely inter-ested in using the kind of filmmade in the 1880s. For today's filmis so incomparably more respon-sive. It contains minute quantitiesof various molecules we weren'tputting in as recently as 1975. Andby 1985, we'll probably be puttingin other molecules that work evenbetter.

Beauty resides in these mole-cules themselves. Beautiful alsoare the methods by which chemi-cal engineers quickly cut the costof a "new composition of matter"(as patent lawyers put it) so that

There is practiced here atKodak a kind of chemical engi-neering that does not think ton-nage. It operates equipmentlocated in small, quiet rooms. Itobserves biological processeswhich use membranes for separa-tion in either aqueous or non-aqueous solutions. It often preferscontinuous processes to batchprocesses, as in copolymeriza-tions where the end propertiesresult not from just the ratio ofthe reactants but from the preci-sion with which they are broughttogether.

That's why we believe thathardheaded (but not necessarilyhard-hatted) chemical engineer-ing is needed in a temple of

science like the Kodak ResearchLaboratories. A fractional-crys-tallization process like this oneneeds no scaling up to meet theneeds of the factory. But chemi-cal engineering on such a scale isscarcely as common as the analo-gous fractional distillation thattakes place in plumed towersagainst the sky, a sight whichcaptivated countless photo-graphic artists seeking to depictthe essence of industry.Of course, this isn't the only

kind of chemical engineering wepractice, but isn't all engineeringa bridge between science and art?
