the EPR method to determine the characteristic accumulation time and
the lifetime of the molecules in the triplet state after cessation
of the irradiation it becomes possible to determine the molecule
concentration in the triplet state without involving the probability-
ratio coefficients. In view of the uncertainty of the actual value
of this coefficient and this disparity with the theoretical value,
the elimination of this coefficient is considered an advantage. The

TITLE: Milling cutter for machining heat-resistant and titanium alloys
PERIODICAL: Mashinostroitel! no. 11, 1962, 29
TEXT: In forging and die-forging blanks of heat-resistant and: Ti-alloys,
surface cracks appear, which makes it necessary*to increase the machining allow-
ances. In the roughing of blanks with a machining allowance of 10 - 30 mm, the
milling cutters used cause the machine tool to vibrate at cutting depths of more
thim 10 - 15 mm. The Innovator V. G. Gulynin has.suggested a milling cutter hav-
