Dmitrovskiy zavod frezernykh stankov.(Dmitrovsk Milling Machine Plant) could'
not manufacture the pilot model of the modernized "692A" key groove milling
machine. The Kolomenskiy,zavod tyashelogo stankostroyeniya (Kolomna Heavy
Machine Tool Plant) developed a new vertical turning and boring-machine.for
components up to 40000 mm diameter, the Bolshevskiy mashinostroitellnyy zavod
-(Bolshev Mechanical Engineering Plant),manufactured a numberof new pasteurizers
and refrigerators for milk the klimovskiy mashinostroitel'nyy zavod (Klimovsk
Mechanical,Engineering Plant) brought out five new models of looms forzotton,
and linen fabrics, The'efficiency of the new "AT-17.5-V automatic loom exceeds
that of theold~"AT-175-V' model by 12.5%. The author points out that,more thmn.

ABSTRACT: Unipromed'-Institute made extensive research
into the
aeration.of pits and mining rooms at
.
the Dzhezkazgarl Mine. All the tested and pre-
sently-used aeration schemes were found to be
quite inadequate. Only about 15 - 2 Oto' of the
pumped air reached the-side drifts, and it
took 5-10 hours to evacuate fumes and dust
caused by..'Uhe blast.. In principle all the:
.air
aeration schemes are similar. The fresh

is based on the requirement that with a sensitivity of 2 x 10 Oe
the magnetometershould-veliably measure precessionfrequency

in order to ensure,this accuracy in the measurement of frequency,
use was made of the method described by Waters and Francis (Ref.13).
