plodder the current consumption being measured by means of a
self-recording wattmeter of the system D-333. The test results &.n)
repreawted in figure 1 till 5 and subsequently explained, The
Influence of the pept1wation on the prooessing o0nditiona is
evident both from the former investiamtions of the withnrs of thi:a
paper and F D, Oveharenko (Footnote 4) &Yid from the investigations
of ',. V Kukolev and Ya. M. Syrkin (Footnote 5) The m&xim=
output of the plodder is attained by constant number of revolutions
of the worm shaft at the optimum suspension viscosity. The teat
results agree with the former studies of the authors of this paper
and G. V. Kukoley and A N, Korolt (Footnotta6 and 7). Conclusions,
Bantevnite additior,3 to kaolin suspensions and faience materials
inorease the outmt of plodders considerably and lower the c-urrent
consumption. An even g-eater affect is cauSed bv the addition cf
some peptizers. There are 5 figures, 2 tables, &-id 11 references,

OSTRACT The authors d(iscribe their experiments in determining the
wator tetontion properties of various materials such as
kaolin, bentonite obtained from different rogionu clay
and faience masses The experiments have shown that ben-
tonite possess the greatest retainability These experi-
ments were carried out under various pressures and their
results are represented by graphs showing the amount of
water (V) plotted versus the pressure applied (P). The
P V curves of kaolin suspensions and falence masses show
horizontal or 41oped BOC-tiona In cortain ranges of pres-
sure Peptizers increase the water retention properties

PERIODICAL: Ogneupory, 1960, No. 0, pp. 552-356
TEXT: It was the authors' task to elaborate a 1 0adle nozzle lining, which
undergoes only slight wash-out, is not clogged by metal, and warrants a
satisfactory jet without spattering or eddies. Highly aluminous zirconium-
and magnesite iy.serts for the compound pouring ladle nozzle lining were
produced at the Opytnyy zavod (Experimental Plant) of the UNITO (Ukrainskiy
nauchno-iorledovatellskiy institut ogneuporov - Ukrainian Scientific
Research Institute of Refractories). The pouring ladle nozzle linings were
produced at the Chaaov Yarekiy kombinat ogneupornykh izdeliy (Chagov Yar
Kombinat of Refractories), the working processes having been previousiy
elaborated at tne t;xperimental Plant of the Ukrainian Scientific Research
Institnte of Refractories. Technical alumina of ty-pe r 1 (G1) and Chasov

Yar clay 4 1 (Chl ) were used for the production of highly aluminous lb inserts.
Zirconium inserts were produced from finely ground Zirconium witK-a ZrO 2
content of 69%. Chamotte pouring ladle nozzle linings were produced at
the Experimental Plant of the Ukrainian Scientific Research Institute of
Refractories from a mass containing 40% chamotte from Chasov Yar clay 4 1
(Chl), 40% Chasov Yar clay 4 I(Chl) and 20% foundry coke. The highly
aluminous and magnesite inserts, as well as chamotte pouring ladle nozzle
linings were pressed in the "Tagilets" friction press. A press mold
(Fig. 1) was used at the Chasov Yar Kombinat. A total view of the two parts
of the compound pouring ladle nozzle lining is shown in Fig. 2. The inserts
and linings were fired in periodic furnaces. The firing curves are shown
In Fig. 3 and the properties of the fired producto are tabulated. The com-
pound linings were tested at the Stalinekiy metallurgioheakiy zavod
(Stalino Metallurgical Plant) and the zavod "Krasnoye Sormovo" ("Krasnoye
Sormovoll Plant) during the casting of rimmed steel. The experiments were
conducted by collaborators of the Ukrainian Scientific Research Institute

shows highly aluminous inserts after their use In 50 t pouring ladles.
They were tested at the "Krasnoye Sormovoll Plant with apertures of 30 mm
diameter. The aperture of the insert was washed out by 1-2 mm in diameter
when casting rimmed steel of type 30r (3kp). The wear amounts to 4-6 mm 6-1-
when casting weld steel of type CB 06A (SvOBA), which is explained by its -
higher content of iron oxides. The authors state in conclusion that the
production technology of compound nozzle linings was elaborated for con-
tinuous rimmed-steel casting. The compound lining consists of a porous
chamotte pouring ladle nozzle as a carrying part, and a highly aluminous
magnesite- or zirconium insert as working part. The highly aluminoua
inserts showed the beat wear resistance during tests. There are 4 fi&nireB,

In this paper, the authors describe experiments with sleeve
bricks with different sleeves (Fig 1). N. P. Mayorov,
N. S. Agazorlyants, A. V. Khribkov, A. M. Makushin, L.B.Shen-
derov, V. G. Baraukov, an&__Z_._T_._A))uladz~ partf-cipated in the
experiments. Table 1 shows the chemical composition of the
sle*ve bricks and the sleeves. The casting conditions of steel
and the wear of the sleeve bricks in a plant for continuous
steel casting are given in table 2. Figure shows a biceramic
sleeve brick with a layer of high aluminalcontent after use.
In conclusion, the authors mention that unbor nt sleeve bricks
with a magnesite layer show a higher wear resistance than
those with a clay-graphite layer, Sleeves of highly re-
fractory materials showed the highest durability. There are
2 figures and 2 tables.

ABSTRACT The authors are inclined to look upon the good qualitative
agroemost of theory with the experiment, which was obtaired
by S.R. Hall and W.F. Vines (Proo. Roy. goo., Vol. 1, 23B,
pp. 204, 215) as largely due to chance. Besides, an in-
definite empirical constant oocurs in this calculation.
The authors compu*ed the scattering of rotons by the
vortox threads in ju&siolassical approximation. For the
force acting upon the unit of length of the thread the
following result is obtaimed (the method of denotation
being the same as with H.E. Hall and W.F. Vines):

On the Absorption of the Second Sound in Rotating Helium II.
56-2-35/47
Circulation round the vortex is assumed to be equal to
9, a 2R I/a. Next, two further coefficients are computed.
Comparison with experimental data is, 6f course, possible
only in that domain in which it is possible to speak
of a "roton gas" and in which the range of the rotons Is
small in comparison with the spacings between the vortex
threads. The computed values of coefficients are mhown in
form of a diagram. Though they agree well with the
measurements carried out by Hall and Vinen at high
temperatures, they are already too low at 1,30. This
tends to confirm the complicated character of the later-
action of the rotons with the vortices, which is not
reduced to simple scattering. When the rotons fly past
at a small distance from the axis of the vortex processes
apparastly take place which have the character of "strong
intoractiol". They lead to the transmission of an impulse
of the order of the total rotou impulse. Also the "smearing
out" of the vortex because of its eigemosoillationa may plV
an essential part. The attempt can be made to describe
this interaction in a phenomenological manner by intro-
ducing a temperature-independent cross section ("breadth")

PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959, Vol 37,

ABSTRACT: The authors find general formulas for the determination of the
thermodynamic quantities (chemical potential) of a liquid film,
and they find the limiting laws for the dependence of the chemi-
cal potential on the thickness of the film. The difficulties
in the generalization of the formulas derived for the vacuum in
the case in which the interspace between the bodies is filled
with any medium, are now eliminated because of the general for-
mulae (Ref 2) already derived for that part ol the thermodynamic
quantities of any absorbing medium which is conditioned by the
electromagnetic fluctuation field with the wave lengths X.~>a
(a denoting the interatomic distances). This field corresponds
to those forces which have the same nature as the van der Weals'
forces between the single molecules at large distances. At
Card 1/3 first, the stress tensor in a stratified absorbent medium is

Van der Waals' Forces in Liquid Films SOV/56-37-1-36/64
calculated, and in the next part the forces of molecular inter-
action between solids are determined. In the case of a metallic
"intermediate layer" between the bodies, the force of molecular
attraction passes from the law 1- 3 at "small" distances to the
law 1-5 at "large" distances. The authors then investigate a
liquid film on the surface of a solid body. This film is as-
sumed to be applied to a wall vertically arranged in the field
of Cravity. F(l) + FCZ - const is the condition for the con-
stancy of the chernical potential along the system, for F(l) is
the part of its chemical potential p depending on the film
thickness. Thus, p - 4 0 + P(l), Po denoting the chemical po-
tential of the "massive liquid". Further, p(1) + Fgz - 0, the
function p(l) determining all thermodynamic properties of the
film. The authors then investigate some typical cases which
ma~ be present according to the character of the function p(l):
(a if p(l) is a monotonely falling, everywhere positive func-
tion, the liquid does not moisten the solid surface, and no
field is formed. (b) If p(l) is a monotonely increasing, every-
Card 2/3 where negative function, this usually corresponds to a liquid

which completely moistens a solid surface. On a vertical wall,
a film with a thickness tending to zero at z --~ m is particu-
larly formed. This decrease in thickness takes place at first
-1/4 -1/3 -
according to the law 1 -z , then according to z . Subse
quently, the contribution to the chemical potential caused by
forces of nonelectromagnetic origin is estimated. Finally, some
films of liquid helium are specially investigated. The authors
thank the Academician L. D. Landau for the discussion of the
problems investigated here, and Professor B. V. Deryagin for
the supply of his papers. There are 3 figures and 21 references,
10 of which are Soviet.

A~_'TRACT: The prejent "Letter to the Editor" is intended to derive a
formula deucribing the interaction energy of particles suspend-
ed in a liquid, which is in interrelation with the Van der Waals
forces. The distance separating the particles from one another
should be large compared to their dimenaions. In princiFle, this
task ma~ be solved on the basis of the general theory of Van
der Wapla forces in diolectrica. The expression I or th- In t. r-
action :orces of an arbitrary body in a mediuz may be ottalned
by a sim;le transformation from the corresponding expreasi~,n for
the interaction forces in the vacuum. The expression for the
additional presaure in a medium with the dielectrio consta-rit 6
atay be obtained from the expression for the pressure In the
vacuum. By uaing the formulas by Landau and Lifshite for the

Boltzmann, Fokker-Planck and Landau in the case of a Coulomb
Interaction betwepn the particles. The knowledge of these
fluctuations is essential to the theory of scattering of electro-
Magnetic waves in rarefied gases and electron plasma. The method
employed is analogous to that used by L. D. Landau and Ye.M.
Lifshits (Ref`,2~ Electrodynamics of uniform media M., Gostekhizda~
1957, Ref.3: ZhETF v.32 61b, 1957). It consists in the

to know n4. n4 may be determined by formulas of A. V. Gurevich, but here it
q q
is shown thatit is easi-er to determine it directly from the equation of motion.
The method brought here to determine n4 is also more exact, and it is Pos-
q
aible to take into account effects occurring at small q , which is not pos-
eible with the Wrevich method. General formulas are first derived for the
case wher.e the body is moving much slower than the thermal electrons
(V -~ IkT m) .In this case the electron density is a function of the potential
ac2ording to Boltzmann: n p(e,s/kT). After extensive calculations the
fo-iowing expressions are .;t'ain"ed:

V4 + V*'0 is the ion velocity in a coordinate system moving with the
body, M is the ion mass. The electron donsity decreases in proportion to
1/ 2; this agrees with Gurevich. Furthermore, a formula is derived for
I(i); its calculation requires the knowledge of the law of ion scattering on
a body with the electric field being taken into account. Though this

TITLEt General theory of the Van der Waals forces
Pl:-fiIODICAL: Uspekhi fizicheskikh nauk, v. 73,- no. 3, 1961, 381-422
TEM A brief report is first given of the methods of the quantum field
theory, and the general theory of the Van der Waals forces is then ex-
plained on this basis. Such a theory has beer developed for the first
time by Ye. ... Lifshits. The application of the methods of the quantum
field theory to the problems of statistical physics at finite temperature
is based on a paper by Matsubarn. According to it, the free energy can be
calculatel by the rules of Feynman's graph technique. Matsubara's
technique can be appreciably improved by taking account of some general
properties of the Green functions (A. A. Abrikosov, L. P. Gor'kov,
I. Ye. Dzyaloshinskiy, ZhETF .31, 799 (1959), Ye. S. Fradkin, ZhETF 6,
