length of time and the labor spent in testing the test is carried Out on
one and the same small lot of bearings, for example ten units,, which oper-.'

TOPIC TAGS.- self lubricating bearing, ball bearing, solid lubricant, teflon
ABSTRACT: Based on the work of Soviet and foreign authors developing self-lubricat
ball bearings\/6nd on the experimental work performed at MIM, the following
conclusions are reached. Ball bearings with massive separators made of teflon
4 and a special lubricant are acceptable for unlubricated operation under-aTm-ospheric
conditions at normal temperatures. They provide a useful life of 100 and more hours
at a speed parameter of d-l' IL n 40 000 mm/rev/min. Lubrication is provided by
gradual wearing of the separator. Characteristics of a failing unlubricated bearing
are increased noise during operation and a rapid rise in or-~rating temperature,
measured on the outer rings (by 10-15C or more), -which is due to destruction of the

bearing separators are discussed. The gyroscopic torque of the ball is given as

ABSTRACT: The determination involved the use of a-reaction forming a phosphora
to establish the op-!
niobium-molybdenum complex (PNMC). ThIe object of the study was
timum conditions for the formation of PNMC at highnioblum concentrations. 1he effect
of various factors * on the formation of PNMC was followed by measuring the optical
density of the yellow form, of this complex in sulfuric acid solutions containing oxalate and
tartrate tons. The optimum temperature was found to be 20C (at higher temperatures,
only apbo8phorus-molybdenumcomplex (PMC) is formed). The formationof PNMC was
complete in 45 min. The optimum content of phosphate, NaZ"04,42HgO, and mdybdate,
(NH4)2MOO4, was also determined. The IbIlowing elements were found to Interferevith

PERIODICAL- Vestnik mashinostroyeniya, no. 11, 1961, 50 - 54
TEXT.- The author developed a new high-production. met-h-od. of
helical cross-rolling of components with a profile as used for
spiral drills. This can be applied to diameters from 1.5 to 12 mm
or more- It consists of a single pass rolling of the entire profile
by one or two pairs of opposing rollers, inclined in respect of t Ile
blank by an angle corresponding to the helice of the drill. Fou_r
rollers in theoworking position form a closed drawing plate of the
profile with insignificant clearances between the adjacent- rollers.
This ensures an axial drawing of metal by all-round radial compres-
sion, and improves the plastic properties of the metal, permit-tIrIg
a single pass rolling of drills from P18 (R18) high-s-peed steel.

the great closeness of the melting temps. (1074. 1074.

nitich by the ionic banding in the solid crystal, but by the
changes of bonding that take place after fusion; stronger
lionding in the wild state seems to give fist to weaker
tk)luting In the liquid state. The Increase of volatility
from Na to Rb Is attributed to polarization of the cation
by the 0 atoms of the 80a- anion and corresponding
shift from ionic to polar bond, which effect increases from
N*a to Rb, but plays no role in the cose of the very small Li.

Temperature," Lab. of Inorg. Chem., Moscow State U., Zhur. Obahch. KUM... !a
No.5, pp 758-765, 1952
The temp, condtns of the beginning of visible evaporation of chlorides of
alkaline elements in gaseous media (air, hydrogen chlorlde,water vapor) were ttudied.
In air, volatilization starts at the following temp: LiCl 5500, NaCl 75000 KC1 65001
RbC1 6500, CsCl 5500. The volatilization temps in a flov of hydrogen chlorideor
water vapor were the same within a gange of = 500. The above compda become
visibly volatile at temps 50 to 1220 lower than their malting points. Vaporization
proceeds considerably faspr in a stream of water vapor than under heating in air
or in hydrogen chloride. At the temps of the acpt (550-8000) this process is not
accompanied by hydrolysis. 258T15

Abstract To study the isobaric and isother=al dehydration of the
hydrates of 4-substituted silicotungstate of potassium
f quartz spiral balance. The existen-
(1) use was mde o
ce of hydrates containing 10, 5j 1.5, 1.25 and 0.5 H 20
was ascertained. Most strongly are retained 0-5-1
mole H20- With such a degree of dehydration the salt
adds reversibly 8 raoles of H 0. Final dehydration and
2
complete decomposition of the salt occur at 500P.
Results of teasinetric investigation are in agreement
with the data on dehycU-ation on the quartz balance.
Thermal analysis of I reveals 4 endotherml effects

Abst By a thermographic study of mixtures of Nb.,,05-(I) and
NaOH (II), taken in different proportions by weight, it
was ascertained that I reacts with II at.130 to form
KayNbOs-(III), which Ts present in the PlIkall melt in
equilibrium with the excess of II. It is shown that the
niobates: NaNbOj-3-5H.-,.O, Na,#WAO.77-32H,~-O (17) and
NaNbO3 interact at above 1000 with II to form III& Thus
III is formed in melts containing excess II. The authors
assume that the process of interaction of Na-niobates
with II takes place with a slight exothermic effect but
the latter is masked by the endothermic effect of the
