THIS IS UNEVALUATED INFORMATION
The ultra=-sonic device for material testing .U tra~.hal -.yea t --t. ff+.rT?ji.fger 'L
n .w being developed at. Oarl Zeiss Jena* is based on the ultra -scni-,;
picture Tr:ethod., Its purpose is to test relatively thick -meta 1 tod', el
su h as rails, cables, crank shafts, pistons connecting rods _ etc
estin ; ower'of the Zeiss model is to be adequate for iron f:i tes ~f
up to 15 centimeter thickness and. for alumininn plates up to 3(, cent.Lmee ers
thick If is, however, also to test very thin r2eta.1 sheets.
The main, body of the device is a cast aluminum cylindric :? fray: e w?_ .h a
diameter of about one meter and a height of two meters; the top; ;.f ,ht
f ra?ne is dor e--shaped.. A large aluminum tub is partially inserted
the lov.er part, of the frarkin such a way that it takes up ahcrl~t tw=) thirds
of the fr?ame's width and half of its height., The 'pub contains i'aYls ?.,
About: 7. 1.--tway between the bottom of the frame and the upper e.c f--e of ~,,.hr
tub, a tube 10 centimeters in diameter Leads from the frar-,e jer they Luba
The testing, object is placed in the water o;iposite the tube e er,.inf
The ,b je:t., thus, is between the opening and an ultrasound source on the
far side of the tub- at the same height, Ultrasound waves emanating
from the source will pass through the testing object and thrcv;;t the
o_oeni.np into the interior of the frame; there they will nee-, .'til"
.
under w ter, e plate glass mirror suspended at an angle of 45 degrees
in the middle of that part of the tub which is inside the frame, 1'-on.
there? tre ..dyes are reflected onto a thin cellophane foil p.Lgrced ab-eve
the ? + rrrcr at some distance from it. Passing through the foil,, the
waves retch the water surface where they form a relief picture,. This
picture is lighted by an incandescent larp of 100 watts.

For the ' functionin , of the device, it is essential that the foil hr: ve

rad-Fation, If it has this strength. the picture of the object ill

wi-Join the tub allows the horizontal and vertical shi ti:if of the object,
so t,hnt the whole piece cart be examined by gradually shi'tinp the
section exposed to ultra-sonic radiation,
Through an arrangement of mirrors placed between the ultra-sound source
and the tube opening, the ultra=sound beam can be passed through
the testing :Eject obliquely, This ha to be done when, testing very
thin objects in order to prolong the peth of the ultra-sour,d beam..
