Photoelasticity is an experi— mental method of determining Stress by applying loads to trans- arent models of real objects in a polariscope and analyzing quan- titatively the pattern produced by the inteiaction of the polmized light with the model. . Until recently photoelastic- ity has been confined mainly to two dimensions, the stress in depth assumed to be con- stant. In three-dimensional work, studies have been limit- ed to symmetrical objects. The study today rests, in the ain, on the ability to permanently reeze or fix a pattern into a ma— erial after the loads have been Progress in three- photoelasticity has en accelerated by the develop- ent of “Foster-ite” a material of stability than previous been tarts veins cocci [appointment fiam Levin, ME 6, has received 11 appointment to the U.

It is highly probable that few people realize the scope of the Armour Research Foundation's operations, including not only domestic but foreign operations. Standing out among its foreign projects is the “El Plan Armour,” successfully operating ever since; This plan has given technological assistance which enables nations, such as those in Latin America, to import U. 8. technology with a minimum depletion of, dollar re- serves. ’I‘he latest step in the plan was the construction of a new labora— tory building in Mexico City (pic— tured above). This modern struc- ture, occupying 1,500 square feet, was built by the Banco de Mexico, SA. It is run by the Armour Research Foundation in the interests of Mexican technou- logical development, giving Mexi- can enterprises the same level of scientific aid that is enjoyed by in- dustries in the United States. The “El Plan Armour" was brought to Mexico in 1944. at the request and sponsorship of the Banco dc Mexico. Its first step was a nation-wide technological audit conducted by U. S. and .Mexl~ can scientists. ARF sent a care— fully selected group of its staff who made their homes in Mexico and did reflect your good taste!

Then, upon specific recom~ inendation by this group, lab- oratory rcsearch and develop- mental pro tarts were started, some of these including the m- dustiialization of cascolate tan— nin, the domestic extraction of quinine, improved methods for the production of oils for leather treatment and finish- ing and the development of tortilla flour. As these technological problems were successfully solved, private Mexican industrial firms began pos- ing a steady stream of research problems on glass, textiles, vita- mins, corn products, and other items. Both the sponsoring agency and the Foundation’s international division work together closely dur» ing the progress of any technical program to guide the work into the most effective channels. The Foundation is continually_ helping Mexico develop its own technical facilities. At the. same time Mexican engineers are being brought to the United States for additional training. ARI“ conducts such pro- grams as “El Plan Armour” on a non~profit basis. In addi— tion, special arrangements are made to reduce operating costs and conserve dollar require- ments by accepting a consider~ able percentage of domestic currency from countries fac~ ing a shortage of dollars. Thus the Foundation’s coopera— tive and economical method of at— tack‘ng‘ diflicult research problems is furthering technological advance in international industry. ital!
