economic aspects of these methods and presents information on
non-Soviet methods of reconditioning of machine parts. The author
states that expenses for repairing represents 10 to 12 percent
of the cost of equipment; and the cost of spare parts is 25 percent
of total repair osts. Five to six percent of the machine tool
capacity is engaged in making spare parts. No personalities are
mentioned. There are 73 references: 40 Soviet, 23 English,
8 German, 1 Czech, and 1 French.

TITLE: The Life-expectancy of Metal Parts With Metal Coatings
(D61govechnost', -detaley s metallicheskimi pokrytiyami)
PERIODICAL: Tr. Leningr. inzh.-ekon.in-ta, 1956, Nr 13, pp 69-85
ABSTRACT: The Author examines coatings applied by smelting, metal
plating, chrome plating, steel plating (electrolytic precipitation
of iron) and electric spark treatment. The life expectancy is
determined in terms of the wear resistance and fatigue strength.
Comparative data on the effect of coatings on the fatigue strength
of steel parts are presented. It is noted that all types of coatings
contribute to a decrease in fatigue strength. The most unfavor-
able effect occurs during the preparation of a surface for metal
plating and the tapping of lacerated threads (its endurance limit
is 49 percent lower than in the basic metal). To increase the
endurance limit of untempered and uncemented cylindrical parts,
the preparation for metal plating can be obtained by knurling;L'the
preparation of hard-surfaced parts is best accomplished by
Card 1/2 electric spark treatment. The best wear resistance for parts in

contact with babbit, bronze, and cast iron is provided by the
porour and smooth chrome, the next is metal plating, then
smelting and, lastly, steel plating. Data regarding the wear
resistance of coatings in terms of the coating thickness are pre-
sented. The wearing properties were determined by the wear
exerted on a coating by a disc made of a hard alloy. It is noted
that smooth chrome is suitable for the coating of parts operating
under relatively low specific pressures. Steel metal coatings
are expedient for machine parts working at small slippage speeds
and relatively low pressures under conditions of liquid friction;
electric spark plating can be effectively used for parts wnrking
in moving connections; steel plating is suitable for use in piirt@
operating in immobile fittings. For parts jointcd in moving con-
nections, steel plating with subsequent chromplating and cement-
ation is recommended.

ABSTRACT: Observations made at a hydrological experiment station on a
7-hectare area are compiled. The study of the migration of
moisture is performed by means of an examination of the moi-
sture balance and the ground-water balance linked with it. A
vertical prism bounded on the top by the earth's surface and on
the bottorh by the deepest level of the ground water is isolated.
The amount of the feeding of the ground water from above is
calculated by the equation of the nonstationary flow in terms of
finite differences (taking into consideration the annual fluctua-
tions of the ground-water level, data on the volume of the flow,
the permeability and the volume of the ground-water outflow).
The balance of moisture is calculated from the volume of the
Card I/Z surface feed and the change in the level of the ground water

SOV/124-58-7-7784
On the Migration of Moisture in the Earth and in Soils
for a known period of observation. -'he volume of the moisture exchange be-
tween the earth and soil and the atmosphere is determined from the equation
of the earth and soil moisture balance of the prism. Using the z-noisture-ex-
change value and the variation in the moisture capacity in the different layers
of the balance prism, a diagram of the moisture migration is plotted. The
investigations have shown that the top layer of the soil-ground prism is char-
acterized by the greatest mobility of the moisture. The middle layer (below
0.9 m) has a relatively stable moisture content. In summer this layer is the
principal conductor of upward and downward currents and during the autumn
and winter periods it accumulates the moisture, storing it until spring when
it is released into the grOUnd-water flow. Bibliography: 5 references.

ume of t-i--,e chamber is surrounded by a hydro-en bath connect-
ed to the hydrogen reservoir. In this way good screening
of the chamber from thermal radiation is achieved and th@?
problem of temperature stability is simply resolved by tLe
stabilisation of the pressure in the reservoir. An important
feature of the cha-mber is the method of mounting of the glass

walls of the chamber. This is illustrated in Fig.2. The
Pyrex windows are mounted on copper washers as shown in the
latter figure a-ad this was found to be very satisfactory,
The method of illumination is described and is illustrated
in Fig.3. A typical oscillogram. of the workling cycle is
shown in Fig.4. The chamber can be kept at the lower press-
ure for 30 to 40 millisees but this time can be varied. The
re-establishing of the pressure to the upper value takes
approximately 15 millisecs, Normally, the upper pressure is
7 atm and the lower 3 atm. A series of photographs was also
taken with pressure reductions down to 1 to 2 atm. Special
experiments have shown that the sensitive time is not less
than 40 milli sees. The repetition frequency of the working
cycle is about 7 to 10 cycles per minute. Fig-5 shows a
photograph of tracks obtained in the neutron beam of a

ABSTRACT: A photographic setup for hydrogen bubble chambers of
large dimensions is quite different from that for Wilson
and diffusion chambers. In particular, a gas bubble in
liquid hydrogen scatters light mainly in the forvard dir-
ection, most of it between 0 and 1.00, say (cf Fig.1)0 so
that it is impossible to photograph*the tracks at go to
the incident light as is done in the usual chambers. For
small bubble chambers the photographs may be taken with
direct transmission in which the source of light is on the
one side of the chamber and the photographic camera on the
other (Refs-3-5). However, it is very difficult to use
this system with a large hydrogen chamber since it is des-
irable not to employ large glasses as it is difficult to

authors have therefore developed a method of illuminating
and photographing on one side of the chara-ber only. This
method was tried on the working hydrogen chamber described
in Ref.5 (this issue) and is shown in Fig.2. The back wall
of the ciamber was in -the form of a spherical mirror, at the
centre of c-jxvature of which the source of light was placed.
The li-ht reflected from this mirror is focussed back again
at the so-Lrce am-d does not enter the objective of the photo-
gra-phic, camera (B in Fig,2). The light which after raflect@-
ion is scattered by the bubbles does enter the photographic
camera qrd ;:,-ives rise to -the track images (Fig.3, facin
:F' 9
p-35). The main disadvanta,-re of this method is that in
addition to the real ima-es one -ets the virtual ima-es as
well but these can be reco-nised by inspection or by a
measurement of track co-ordinates by means of 2 stereo-
photop-raj@..hs (the virtual iMaSe lies behind the mirror). A

normal superheating of the liquid is effected [takes place]
when the pressure in the chamber up before expansion 1.3
equal to two-thirds of the critioal pressure. This con.-
dition may be easily satisfied if the chamber and the bath
is filled with liquid deuterium. However, if the bath is
filled with liquid hydrogen and the chamber with liquid
deuterium, then it is impossible to obtain pressures
greater than 8 atm in the chamber. For this reason it
was feared that on expansion the superheating of the
deuterium would be insufficient and the liquid would be
insensitive to radiation. Exper 'iments made to elucidate
all these points have shown that it is possible to use
deuterium as the working liquid in the bubble chamber
without Any special purification. The construction and
operation of the deuterium chamber is similar in many
ways to that of the dydrogen chamber. The bath was
cooled down to, liquid nitrogen temperature and was filled
with liquid hydrogen. The chamber was then filled with
technical deuteriwa which was not sp@cially purified to
i,emove tritium. The pressure in the hydrogen bath was in-
creased to 12.4 atm and was kept at that level. After the

correlations were obtained in the three-particle processes M-and
(4); these characteristics could not be obtained by earlier pro-
cedures. The liquid-hydrogen bubble chamber makes it possible to
carry out an exhaustive study of all pp scattering processes in a
single experiment. It was confirmed that the cross section for pion'
1 p@Lir production in this energy range is negligible. "In conclusion ,
we thank the technicians and laboratory assistants for good operation
of the liquid-hydrogen bubble chamber, the scanning group of ITEF
