4. "Since l 52.the 'telegraph-building' battalions of the Soviet communications
troop8 have 'been provided ' with `the 'Apparatus 'IL-1' - (rmpulany Zzmeritel
Linii - impulse-"measurer of the line).
5. "By means of the IL-1 apparatus one can find in one minute where a telegraph
or telephone line has been damaged. The range of the apparatus is up to 50
IQs. The IL-i apparatus is connected with the line (wire). The generator of
the apparatus sends impulses into the wire. On the radar principle, the
impulses are fully or partly reflected from the damaged spot any show the
distance between the damage and the place where the apparatus is connected to
the line-on the screen of the apparatus.
6.."The IL-i. has been constructed by the Ts1NNILL (Tsentrelnaia IQauchno-Issledova-
telnaia Elektrotekhnicheskaia Laboratoris - Central Electrotechnical ScientilIc
Research Laboratory in Moscow by the enf;ineers Ye. L. Bykhovski and V. L.
Bakinovski.
7. "The main parts of the IL-1 apparatus are: a N.aliarov magnetron arid an
electronic-ray tube, which has a :,Cale on its screen, on which the distance
of the impulse reflection is noted'."
