Show Million-Volt X-Ray to Find Defect in Metal ROCHESTER, N. Y. A giant million-volt industrial X-ray machine, capable of disclosing defects in thick metal castings in a matter of min- utes, soon will be in operation at the University of Rochester. The machine, described as one of the "most powerful in the world," is being installed with the co-opera- : tion of eight local industrial firms, which will share its facilities. Robert E. Frederickson, vice president pres-ident of one of the collaborating firms, described the apparatus, which is housed in a special building build-ing of extra-thick concrete walls, as "completely shockproof." Heavy castings will be moved inside the X-ray room by a 10-ton overhead crane. |
