TEXV, Electrical conductivity determinations are suggested
as a rapid means of determining the stability of additives in
oils to transitions between the colloidal and truly ionic states.
Conventional electrolytic type cells are used, being concentric
aluminium cylinders, 50 mm high, and 20 and 35 mm diameter
respectively. Py incorporating a thermostat bath, thermal
stability to temperatures up to 2500C may be investigated. By
studying change of conductivity with time alone, storage stability
may be determined. Molybdenum blue is found to be indefinitely
stable at room temperature,,-but after a short period of heating
to 1000C, the conductivity suffers a sudden and permanent decrease.
By contrast, the conductivity of molybdenum nonyl-xanthen,,ate

solutions increases to a maximum after-about 400 hours storage,
then falls to a lower, but stable, value after about 600 hours.
On taking a series of straight lubricating oil fractions from a
high-sulphur crude, and plotting their conductivity versus
viscosity a distinct curvature is obtained-,,in apparent violation---"
,of Waldenis Rule. It clearly shows that the~concentration of
electrically conducting material increases with boiling point. On
heating straight oils with or without thermally stable additives
to 250*'C, little change in conduotivity is found on cooling, but
with unstable additives, the heating curve is much higher than the
cooling curvo over a cortain bigh temporaturo range, but rojoine
It at lower temperatures, thus exhibiting a hyateresia-type curve:
this is attributed to a shift at high temperatures of the reaction
between colloidal micelles and ions. By plotting conductivities
versus conGentrations, the conductivity of phenolate solutions is
~seen to be iol.Lic, but that of sulphonate solutions micellar. There

known correlation between good anti-wear properties and high

additive components should overcome the effect of delayed E.P.
action in high-speed friction tests. in surfaces subject to high
speed friction there is not always time for the E.P. additive to
operate. For laboratory tests of two component additives the

authors developed radiotracer methods of determining the chemical
~ac,tivlty of E.P. additives in oils in the presence or absence of
friction. The chemical activity of the E.P. additives was
assessed by determining the kinetics of solution of radioactive
steel In oil or of copper which was activated with A9110.
Determination of the chemical activity relative to radioactive
copper and steel were made with various sulphurised and
chlorinated organic compounds and mixtures of these. For example,
in tests with copper foil at a temperature of 150 OC it was found
that chemical activity of the sulphur-containing additive
dibenzyl disulphide and that of chlorinated wax were both much
less than the chemical activity of a mixture of these additives.
.A mixture containing base oil plus 3% d1benzyl disulphide plus
7% chlorinated wax -gave the beat E.P. protection in the four ball.
test. When 6% of barium alkyl phenolate dissolved in
oxpropylated alkyl-phenol was.added to the oil containing
dibenzyl disulphide and chlorinated wax there was a marked
diminution in corrosivity of the oil without impairment of the
E.P. properties. However, the reduced corrosivity to copper
lasted for only ton hours, The anti-corrosion propertioB of

phosphorus-containing compounds wer6 also tested on the
assumption that effective protection of metallic surfaces against
corrosion by atoms of chlorine and sulphur can be achieved by
creating$ not a molecular, but a more continuous atomic film which
is less penetrable. To create such films the~phosphorus-
containing compounds must be soluble in the base oil and release
phosphorus at considerably lower temperatures than the
,decomposition temperatures of the E.P.,components. It was indeed
found that the use of phosphorus-containing additives ensured
effective reduction of corrosion of steel at an oil temperature
of 200 OC in the presence of a mixture of dibenzyl disulphide and
chlorinated wax. Moreover, four ball machine tests showed that
the E.P, properties were not impaired. Tricresyl phosphate had
no anti-corrosive effect, whilst triphenyl phosphate caused a
marked reduction in corrosion. By using phosphorus-containing
anti-corrosion components in blends with more chemically active
E.P. additives, effective-blends may be made using chemical
compounds that hitherto have been rejected because of their high
corrosivity. E.P. oils were tested on a friction machine in which

-the rubbing surfaces are the ends of two hollow cast iron
cylinders of.116 mm external diameter, one of which was radioactive.
The tests were made at a speed of 600.r.p.m. with a load of
2.5 kg/CM2 for a period'of-one hour. Typical teat results show,
that the base oil gave a mean wear rate of 66o impulses/min of the
counteri the base oil Plus 316' of additive J13-6/9 (LZ-6/9) plus
.7% chlorinated wax gave a wear rate of 1920 impulses/min. The same
plus 0.5% triphenyl phosphite gave'a wear rate of-840 impulses/min.
Thus the triphenyl ph.osphite reduced tho corrosivity of the E.P.
oil to the level of the base oil. - There are 3 figures, I table

which-indicated that the additive mixtures dissociated to a
considerably higher degree.than the single additives. Experiments

deposition of 'soot particles labelled with T-`204 on the hot plate
and adsorption of the add�t!vez.wIth labelled Ca atoms on the metal

the degree of additive dissociation, the more effective its
detergent activity. For a number,of alkyl phenate additives the

conductivity, pr esumably due to their.low solubility. All batches

TITLEt Large-scale mechanization of the sinking of vertical shafts
PERIODICALs Gornyy zhurnal, no. 1, 1960, 44-46
TEXTs The sinking of shaftei (usually to a depth of from 700 to 1000 m) in
the Krivorozhakiy basin largely determines the total construction time of
the mine. :In 1957, the trent Krivbassahakhtoprokhodka (Krivbass-
shakhtoprokhodka Trust) was established in the Krivorozhskiy basin,
similar to the other trusts in the coal mining industry, in order to in-
crease the speed of sinking vertical shafts. Starting in August 1957,
the collective of engineers and technicians has taken a number of important
measures on thebasis of experience made at home and abroad. Concrete of
high early strength is used for reinforcing the.shafts, Metal casings
(Fig.1) developed by engineers of the Trust are used for this purpose.
In most oases concrete is fed to a depth of up to 650 M through a pipeline
as is shown in Fig. 2. Fig. 3 shown a mechanized mixing installation

operated by two to three persons, The control of the loading equipment
in the Novaya-Rakhmanovskays mines, Yuzhnaya Gleyevatskaya mines, and
others was centralized from a control column with automatic blocking of
the loading equipment and the hoist. Despite the rook hardness of 10 to
20 (according to Protod'yakonov), the measures indicated resulted in an
increase in production. Fig. 4 shows equipment for shaft sinking
according to the parallel process without provisional reinforcing,
developed by the engineers of the Trust. The collective of the Trust

ABSTRACT: Rxpensive chrome-nickel steels with,a nickel content of
12 - 18% are used in the manufacture of the plates (hearths)
of chamber-tgpe electric furnaces working at temperatures of
850 - 1 000 C. The design office of the Blektropech' Trust
souE;ht a cheaper heat-resistant alloy for this purpose which did
not contain nickel or other scarce constituents. A literature
survey on the chemical composition and heat-resistance of steel
and cast iron was first made. Hearth castings of the selected
alloys were tested in industrial furnaces to determine their
life and in the laboratory to.establish their resistance to
scale formation and to heat. This article gives tho test results
on tho different alloys. Chrome-manganese stee34 some contiin-
ing titanium, proved quite unsatisfactory because scale from

them., High chromium steel (22-33%) was rejected on account of
its ansatisfactory casting properties. This also applied to
similar steels containing aluminium. Chrome-Sopper steels opera-
ted satisfactorily at a temperature of 1 000 0 with a lo4ding
of 150 kg/m for more than 500 hours without distortion. The
quantity of scale formed was negligible. High-chrome cast iron
had impossibly bad casting characteristics. However, after te
manganese content.had been raised to ?%, the casting properties
became good. The results of scaling tests at high temperatures
on chrome-magnesi~m.. cast irons are tabulated together with their
composition. Some of these materials worked for periods up to
a year in furnaces. In comparing the mechanical properties of
these steels with steel DIA-417 which contains 18% nickel, it
should be rememberedthat the 30-417 samples were made from
rolled material and the others from cast sheets. When steel
with a minimum nickel content of 12% is replaced by nickel-free
steel or cast iron, the saving is not less than 2.50 RoubleS Der
kg. The various.steels and cast irons were melted in induction
furnaces*with capacities up to 150 kg. It is concluded that

TITLEt Bar.reinforcement
PERIODICALs Tekhnika molodezhi, no. 5, 1961, 12
TEXTt The author points out the difficulties arising from inorenning strata
'
pressure on the roofs of workings in mining.
Among the various systems emp-
loyed for mine roof reinforcement, ouch as props, walls and arches made of
wood, metalq and reinforced concrete, bar reinforcement is considered the most
. Although this method is not new and was men-
dependable reinforcing method
.
tioned in 1878 for the first time, extensive use of the principle started
only recently and is Coing to replace all other methods of reinforcement.
For maximum protection against cave-in of the working roof, metal bars are
inserted into holes drilled in the roof. The bars have a wedge-type or split-
type lock on one end for fantening within the rock and are threaded on the
other end. A nut screwed on the threaded end prensea a thrust plate atainat
the roof of the working-to absorb the pressure of the upper rock layers.
The bars can also be inserted into concrete mortar pumped under pressure into
boreholes drilled in the rock.. The concrete mortar penetrates also into

small cracks and thus binds the rock into one monolithic mass. The nut and
plate are attached to the threaded end of the bar protruding from the bore-
hole. -The main advan.tagos of bar reinforcement are operational safety and
economy in materialg cost and manpower. Fifteen million cubic moteraof tim-
ber can be navad annually, the prime costs xeduced 4 to 5 times, and the work
can- be - mechanized. - A machine ,','or setting bar reinf oroomen'.s - (Fig* 2) is be-
ing tested. It is to drill boreholes, set wooden or metal bars into themq
wedge the bareg-and screw on the nuts. If the bars are to be inserted into
concrete mortars the machine w'JU1 also pump the concrete into the boreholes.

TEXT: The problem of the utilization of nitrogen oxide waste developing
during the manufacture of some products of the organic synthesis is dealt
with in the paper under review. The development of a simple method for
the utilization of nitrogen oxide waste in industry is desirable. The
principal reactions which determine the forming of nitric acid from nitro
gen oxide are mentioned and equations for the reaction rate are given*
The utilization of highly concentrated nitrogen oxides permits the pro-
duction of 55~ nitric acid1lin accordance with the equation of equilibrium
of the secondIreactio.n .(Kp- 1) NO/pN02). The absorption takes place in a
bubbling column which represents an absorber of improved type in the

given case. The high nitrogen oxide oontent in the gas permits also a
simplified gas flow through the eyetem,the gas flow being obtained with
the aid of a vacuum pump of the type RKK (from aoid-resisting alloys).
The arrangement is given schematically (Fig.) and its characteristic
values are given. The oxygen consumption for a daily production of 55%
of HNO amounts to 14 M3/h in alli the dimensions of tha second cooler

are reduced to two servenths, the weight of the column to one fourth, the
number of bottoms to 8, and the consumption of electric power to one
fifth. There is I figure.

TEXT: The authors studied the effect of an addition.of a natural radio-
active substance, uranium, on the catalytic activity of an industrial
catalyst. They compared the catalyst with uranium addition with an In-
dustrial catalyst of the type "Sit ("Bit) (2~6 K2 0 and 4% A1203) and with
the catal yst of the type "ST', ("BT11) with increased Al 203 content
